阅读理解
A
On her first day teaching students from poor families at an after-school program in New York City, Alyssa Kapasi noticed how many kids were lining up for free sandwiches and fruit in the school cafeteria.One of the workers explained that many of these students don’t get enough to eat at home, so a school lunch or an after-school meal might be the most food they would get all day.
Kapasi, who attends private school, was very surprised. What’s more, she made up her mind to help.“I want other kids to understand that if you see a problem, you don’t have to wait to grow up to fix it，”says Kapasi. She and a group of friends are now putting their programming skills to work to create an app called Food for Thought, which will allow parents, students, and even kind-hearted strangers to donate to a lunch account for a student in need at a nearby school.
About 20 million American kids receive free lunches. Two million more can have low-price meals, and those students’ families have to pay for part of their food. When they don’t have the money on any given day，the students might have to settle__for an “alternative(可代替的) meal”such as a cheese sandwich.
The app—which is getting financial(财政的) support from a GoFundMe page—provides anonymity(匿名)to those who receive lunch and donors.To receive help，a family will need only a recommendation(推荐) from a school teacher, and no one else has to know.
“I want to make an app that all users feel no shame in using，”says Kapasi. She hopes to test the app in a school district this fall.
【解题导语】　本文是一篇记叙文。文章介绍了美国纽约市一名叫Alyssa Kapasi的女孩设计了一款应用程序来解决贫困家庭学生的饥饿问题。
1．Why does Kapasi want to create an app?
A．To teach kids how to help others.
B．To practise her programming skills.
C．To introduce her school to the public.
D．To solve the problem of hunger in schools.
D　解析：推理判断题。第一段介绍了Kapasi设计应用程序的缘由——她看到许多在学校餐厅排队领取免费食物的孩子，并了解到很多孩子在家吃不饱；再由第二段中的she made up her mind to help...to work to create an app called Food for Thought 可知，她致力于解决来自贫困家庭的学生的饥饿问题。
2．What does the underlined phrase “settle for” in Paragraph 3 probably mean?
A．Buy.　　　　　　　　　 B．Make.
C．Accept. D．Offer.
C　解析：词义猜测题。由前文中的About 20 million American kids receive free lunches. Two million more can have low-price meals...可知，本段介绍了美国孩子享受免费或者低价午餐的情况。对于那些没有钱支付低价午餐的孩子，他们可以得到诸如奶酪三明治之类的食物来替代午餐。
3．What should a family do if they want to get help from Food for Thought?
A．Visit a GoFundMe page.
B．Get in touch with Kapasi.
C．Be recommended by teachers.
D．Donate something else instead.
C　解析：细节理解题。由倒数第二段中的To receive help, a family will need only a recommendation(推荐) from a school teacher可知，想要获得Food for Thought帮助的家庭，只需被学校老师推荐即可。
4．What can we infer about the users of Kapasi’s app?
A．They won’t lose face in using it.
B．They will make money by using it.
C．They will know who offers them help.
D．They won’t meet their donors until this fall.
A　解析：推理判断题。由倒数第二段中的The app...provides anonymity(匿名) to those who receive lunch and donors和最后一段中的I want to make an app that all users feel no shame in using可知，该应用软件提供匿名服务，这样不会让使用者丢面子。
B
Animals are natural resources that people have wasted all through our history.
Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way.Thousands of kinds of animals have disappeared from the earth forever.Hundreds more are on the danger list today.About 170 kinds in the United States alone are considered in danger.
Why should people care？Because we need animals.And because once they are gone, there will never be any more.
Animals are more than beautiful or interesting or a source of food.Every animal has its place in the balance of nature.Destroying one kind of animal can create many problems.
For example, when farmers killed large numbers of hawks(鹰), the farmers’ stores of corn and grain were destroyed by mice.Why？Because hawks eat mice.With no hawks to keep down their numbers, the mice multiplied quickly.
Luckily, some people are working to help save the animals.Some groups raise money to let people know about the problem.And they try to get the governments to pass laws protecting animals in danger.
Quite a few countries have passed laws.These laws forbid the killing of any animal or plant on the danger list.Slowly, the number of some animals in danger is growing.
【解题导语】　本文是一篇关于动物保护的说明文。目前，世界范围内动物的数量正在不断下降，保护动物刻不容缓。保护动物不仅是为动物，也是为我们人类自己的生存考虑。幸运的是，现在有的国家已经开始行动，例如成立保护组织或制定法律等对动物进行有效的保护。
5．What is the best title for the passage?
A．Save the Animals
B．Useful Animals
C．Laws for Animals
D．Animals in Danger
A　解析：标题归纳题。文章提到动物面临的生存现状、保护动物的必要性以及目前一些国家对野生动物所采取的保护性措施等都体现了保护动物的主题，故文章标题应是“保护动物”。
6．Animals are important to us mainly because ________．
A．they give us a source of food
B．they are beautiful and lovely
C．they keep the balance of nature
D．they give us a lot of pleasure
C　解析：细节理解题。根据第四段中的Animals are more than...in the balance of nature.可知，每一种动物的存在都是有道理的，都是为了维持自然界的平衡。
7．What is the meaning of the underlined word “multiplied”in the passage?
A．Became more. B．Became less.
C．Turned black. D．Ate food.
A　解析：词义猜测题。由画线词所在的段落可以看出，当鹰的数量因人类的捕杀而减少时，粮食受老鼠的毁坏会加重。没有鹰对老鼠的捕杀，老鼠的数量自然是增长很快，即“变得更多”。
8．We can infer from the passage that ________．
A．people have known the importance of animal protection since a long time ago
B．animals play an important role in people’s life
C．the number of hawks is on the decrease
D．many countries passed laws forbidding the killing of any animal
B　解析：推理判断题。根据第一段和第四段的描述可知，此前人们对于动物的保护并不关注，当然也并未意识到保护动物的重要性，故可排除A项。通过对文章第四段的理解可知动物在人们的生活中起着重要作用，故B项正确。文中提到鹰的数量由于人类的捕杀而减少，但并非现在的情况，故可排除C项。D项中提到许多国家制定了法律来禁止对一切动物的捕杀，忽略了文中on the danger list这个说法，故该项是不对的。

野生动物是人类的朋友，是自然生态系统的重要组成部分，也是大自然赋予人类的宝贵自然资源，它关系着人类的生存与发展。让我们一起来了解一下吧！
Why Should We Help Protect Wildlife?
Every year, thousands of animal species become extinct.
Some wild animals are disappearing from our planet forever at a surprising speed.Scientists estimate that the current rate of extinction is thousands of times greater than it would normally be because of one factor—humans.
We are consuming the earth’s natural resources faster than ever.We destroy animals’ habitats，food，water and air, as well as the animals themselves.As more birds’ nests are cleared to build skyscrapers(摩天大楼)，rivers are drained for parking lots and elephants are killed to make decorations, the number of certain animals becomes smaller and smaller.
We may consider the animal world to be separate from our own，but in fact，our lives and theirs are connected in several aspects.Plants，animals，people and the environment together make up a biological
community—an ecosystem—in which each part depends on another for survival.When one part of the community is thrown off-balance(不平衡地) or disappears，the entire system will suffer.
Even though humans are wildlife’s greatest threat, we are also its only hope.Now, individuals and small groups from all over the world, as well as large organizations，companies and governments，are working to ensure a more secure future for wildlife and for us.Through cutting demands for animal byproducts, introducing laws against trafficking(非法贩卖)，and volunteering in organizations that help protect endangered species，people fight with the threats the earth’s wild animals are faced with.
No act of protection is too small.We may not be able to bring back the species we have already lost, but many others on the edge of extinction need our immediate attention and action.Don’t be part of the problem.Be the solution：Respect and protect the earth’s wildlife.

HOW DAISY LEARNED TO HELP WILDLIFE
Daisy had always longed① to help endangered species② of wildlife. One day she woke up and found a flying carpet③ by her bed. “Where do you want to go？” it asked. Daisy responded④ immediately. “I’d like to see some endangered wildlife，”she said.“Please take me to a distant⑤ land where I can find the animal that gave fur⑥ to make this sweater．” At once the carpet flew away and took her to Tibet. There Daisy saw an antelope looking sad. It said, “We’re being killed for the wool beneath⑦ our stomachs. Our fur is being used to make sweaters for people like you. As a result, we are now an endangered species.” At⑧ that Daisy cried, “I’m sorry I didn’t know that. I wonder what is being done to help you. Flying carpet, please show me a place where there’s some wildlife protection．”
◆此处为where引导的定语从句，修饰先行词a distant land。同时where引导的定语从句中又含有that引导的定语从句，修饰先行词the animal。
◆looking sad作定语，修饰an antelope。
◆此处为where引导的定语从句，修饰先行词a place。
The flying carpet travelled so fast that next minute they were in Zimbabwe. Daisy turned around⑨ and found that she was being watched by an elephant. “Have you come to take my photoB10？” it asked. In relief? Daisy burst into laughter?. “Don’t laugh，” said the elephant，“We used to be an endangered species. Farmers hunted us without mercy?. They said we destroyed their farms, and money from tourists only went to the large tour companies. So the government decided to help. They allowed tourists to hunt only a certain? number of animals if they paid the farmers. Now the farmers are happy and our numbers are increasing.So good things are being done here to save local wildlife.”
◆so...that...如此……以至于……，在此引导结果状语从句。
Daisy smiled. “That’s good news. It shows the importance? of wildlife protection, but I’d like to help as the WWF suggests．”The carpet rose again and almost at once they were in a thick rainforest. A monkey watched them as it rubbed? itself. “What are you doing？” asked Daisy. “I’m protecting myself from? mosquitoes?，”it replied.“When I find a millipede insect?， I rub it over my body. It contains? a powerful(drug which affects( mosquitoes. You should pay more attention to( the rainforest where I live and appreciate( how the animals live together. No rainforest(, no animals, no drugs.”
◆此处为as引导方式状语从句。
◆本句中where引导定语从句，修饰先行词the rainforest；how引导宾语从句，作appreciate的宾语。
Daisy was amazed. “Flying carpet, please take me home so I can tell WWF and we can begin producing this new drug. Monkey, please come and help.” The monkey agreed. The carpet flew home. As they landedB26, things began to disappear. Two minutes later everything had gone—the monkey, too. So Daisy was not able to make her new drug. But what an experience! She had learned so much! And there was always WWF...
戴茜是如何学会帮助野生动植物的
戴茜一直都渴望帮助那些濒临灭绝的野生动植物。一天她醒来后，发现床边有一条飞毯。飞毯问她：“你想去哪儿？”戴茜立刻做出回应。“我想去看看一些濒临灭绝的野生动植物，”她说道，“请带我到一个遥远的地方，在那里我可以找到为制作这件毛衣提供毛的动物。”飞毯立刻起飞，把她带到了西藏。在那里，戴茜看到一只羚羊，它看起来很是伤心。它说：“为了取得我们腹部下的羊毛，我们正在被屠杀。我们的毛被用来为像你一样的人们制作毛衣。结果，我们现在是濒危物种了。”听到这些，戴茜哭了：“我很抱歉，我以前不知道。我想知道(人类)为帮助你们正在做什么。飞毯，请带我去一个有野生动植物保护的地方。”
飞毯飞行得如此之快，以至于一转眼他们就来到了津巴布韦。戴茜转过身去，发现一头大象正看着她。大象问道：“你是来给我拍照的吗？”戴茜如释重负，突然笑了起来。“不要笑了，”大象说，“我们过去是濒危物种，农民们毫不留情地猎杀我们。他们说我们破坏了他们的农田，而且游客的钱都被大型旅游公司赚走了。于是政府决定帮助(我们)。如果游客付给农民钱的话，他们就允许游客猎取仅仅一定数量内的动物。现在农民高兴了，我们的数量也在增加。因此，为了拯救当地的野生动植物，人们正在做一些好事。”
戴茜笑道：“那可是个好消息。这体现了野生动植物保护的重要性，不过，我还是想按照世界野生生物基金会的建议来帮助(你们)。”飞毯再次起飞，转眼间他们就到了一片茂密的热带雨林。一只猴子一边涂擦身体，一边望着他们。戴茜问：“你在干什么呢？”它答道：“我正在保护自己不被蚊子叮咬。当发现一只千足虫时，我便把它擦在身上。它含有一种强效的药物可以驱蚊。你们应该更多地关注我生活的热带雨林，并且应该了解动物是如何在一起生活的。没有雨林，就没有动物，也就没有药物了。”
戴茜很惊讶。“飞毯，请带我回家去，我可以(将此事)告诉世界野生生物基金会，我们就可以开始生产这种新药了。猴子，请来帮助我吧。”猴子同意了，飞毯飞回了家。当他们着陆时，一切都开始消失。两分钟后，什么都不见了——猴子也不见了。这样，戴茜就不能制造新药了。但这是一次多么奇妙的经历呀！她学到了那么多的东西！而且，世界野生生物基金会一直都存在……
阅读理解
A
On her first day teaching students from poor families at an after-school program in New York City, Alyssa Kapasi noticed how many kids were lining up for free sandwiches and fruit in the school cafeteria.One of the workers explained that many of these students don’t get enough to eat at home, so a school lunch or an after-school meal might be the most food they would get all day.
Kapasi, who attends private school, was very surprised. What’s more, she made up her mind to help.“I want other kids to understand that if you see a problem, you don’t have to wait to grow up to fix it，”says Kapasi. She and a group of friends are now putting their programming skills to work to create an app called Food for Thought, which will allow parents, students, and even kind-hearted strangers to donate to a lunch account for a student in need at a nearby school.
About 20 million American kids receive free lunches. Two million more can have low-price meals, and those students’ families have to pay for part of their food. When they don’t have the money on any given day，the students might have to settle__for an “alternative(可代替的) meal”such as a cheese sandwich.
The app—which is getting financial(财政的) support from a GoFundMe page—provides anonymity(匿名)to those who receive lunch and donors.To receive help，a family will need only a recommendation(推荐) from a school teacher, and no one else has to know.
“I want to make an app that all users feel no shame in using，”says Kapasi. She hopes to test the app in a school district this fall.

Animals are natural resources that people have wasted all through our history.
Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way.Thousands of kinds of animals have disappeared from the earth forever.Hundreds more are on the danger list today.About 170 kinds in the United States alone are considered in danger.
Why should people care？Because we need animals.And because once they are gone, there will never be any more.
Animals are more than beautiful or interesting or a source of food.Every animal has its place in the balance of nature.Destroying one kind of animal can create many problems.
For example, when farmers killed large numbers of hawks(鹰), the farmers’ stores of corn and grain were destroyed by mice.Why？Because hawks eat mice.With no hawks to keep down their numbers, the mice multiplied quickly.
Luckily, some people are working to help save the animals.Some groups raise money to let people know about the problem.And they try to get the governments to pass laws protecting animals in danger.
Quite a few countries have passed laws.These laws forbid the killing of any animal or plant on the danger list.Slowly, the number of some animals in danger is growing.
【解题导语】　本文是一篇关于动物保护的说明文。目前，世界范围内动物的数量正在不断下降，保护动物刻不容缓。保护动物不仅是为动物，也是为我们人类自己的生存考虑。幸运的是，现在有的国家已经开始行动，例如成立保护组织或制定法律等对动物进行有效的保护。
5．What is the best title for the passage?
A．Save the Animals
B．Useful Animals
C．Laws for Animals
D．Animals in Danger
A　解析：标题归纳题。文章提到动物面临的生存现状、保护动物的必要性以及目前一些国家对野生动物所采取的保护性措施等都体现了保护动物的主题，故文章标题应是“保护动物”。
6．Animals are important to us mainly because ________．
A．they give us a source of food
B．they are beautiful and lovely
C．they keep the balance of nature
D．they give us a lot of pleasure
C　解析：细节理解题。根据第四段中的Animals are more than...in the balance of nature.可知，每一种动物的存在都是有道理的，都是为了维持自然界的平衡。
7．What is the meaning of the underlined word “multiplied”in the passage?
A．Became more. B．Became less.
C．Turned black. D．Ate food.
A　解析：词义猜测题。由画线词所在的段落可以看出，当鹰的数量因人类的捕杀而减少时，粮食受老鼠的毁坏会加重。没有鹰对老鼠的捕杀，老鼠的数量自然是增长很快，即“变得更多”。
8．We can infer from the passage that ________．
A．people have known the importance of animal protection since a long time ago
B．animals play an important role in people’s life
C．the number of hawks is on the decrease
D．many countries passed laws forbidding the killing of any animal
B　解析：推理判断题。根据第一段和第四段的描述可知，此前人们对于动物的保护并不关注，当然也并未意识到保护动物的重要性，故可排除A项。通过对文章第四段的理解可知动物在人们的生活中起着重要作用，故B项正确。文中提到鹰的数量由于人类的捕杀而减少，但并非现在的情况，故可排除C项。D项中提到许多国家制定了法律来禁止对一切动物的捕杀，忽略了文中on the danger list这个说法，故该项是不对的。

106 leopards(豹) died in the first two months of this year in forest areas across India.According to the Wildlife Protection Society of India(WPSI)，which provided the data, many of the deaths were very likely caused by poaching(偷猎)．Only 12 of the big cats died of natural causes. Uttarakhand tops the list with 24 leopard deaths, followed by Maharashtra(18 deaths) and Rajasthan (11 deaths)．The incidents of deaths were reported from 18 states.
According to official records, a total of 431 leopards died in 2017. These included 159 incidents of poaching. Some 450 big cats died in 2016 and 127 of them were found poached.Leopards have been targeted by poachers for their expensive furs and other body parts. However, habitat loss, especially due to farming, has caused a new threat to them.
According to experts involved in tracking illegal wildlife trade, when an animal skin reaches a possible market, it can fetch around Rs.50 lakh(五百万卢比)—sometimes even higher than that.A poacher in India sells it to someone for about Rs.3－4 lakh. It reaches a trader in Nepal or other neighbouring countries, where it is sold for Rs.8－10 lakh. The traders in Nepal and other countries then send the animal skin to its final market. By the time it reaches the final trader, an animal skin can get Rs.40－50 lakh, experts said.
The WPSI said there are 10 possible general causes of leopard deaths. Of 106 leopard deaths so far this year, there were 18 cases of poaching.There were clear signs of gunshot wounds or trap marks or poison found on an animal’s body. The WPSI said eight leopards died in road or train accidents in January and February this year; five were killed by villagers; seven died during fighting with other leopards; five were killed by tigers or other animals. Beside this, four leopards were rescued alive，the WPSI said.

A．he will send it to the final trader
B．it will change hands many times

A
Various animals are respected and even worshipped(崇拜)in different cultures.In Hinduism, for example, cows are valued for their gentle nature.However, in ancient Egypt, crocodiles(鳄鱼) were regarded as living representations of the god Sobek.
During the serious drought in the 15th century, the Mossi were led to an undiscovered pond by the crocodiles. This not only allowed the Mossi to survive, but also led to the founding of the village Bazoulé.
As the villagers owe their survival to the crocodiles, they now care for and live side by side with them. The villagers even bury the crocodiles and hold funerals for them after their death.The crocodiles are not only regarded as protectors of Bazoulé， but also fortune-tellers that give best wishes to the villagers. It seems that the worship of the crocodiles has paid off. For over 70 years, there has never been a death from a crocodile attack in Bazoulé.It’s normal for women to wash their clothes in the water and gather plants nearby. And it is also normal to see children playing around the water where the crocodiles live.
Naturally, this strange relationship between the villagers and crocodiles has attracted a lot of attention. Tourists from all over the world come to the village, hoping to catch sight of this unlikely bond between humans and crocodiles.Visitors have the opportunity to buy a chicken, with which they can attract the crocodiles out of the water. You can pose for pictures, and if you’re brave enough, you can sit on a crocodile’s back just like the local children usually do.
The village is trying to develop its tourism, but unfortunately, it was found to be threatened by global warming.Lower annual rainfall means that the pond will vanish one day. Perhaps the legends are true, and when this happens，the crocodiles will lead the Mossi to a new water source.
【解题导语】　本文是一篇说明文。文章主要介绍了非洲的巴扎村里凶猛的鳄鱼和人类长期和平相处，这一和谐现象吸引了无数游客慕名而来。
1．Why were the Mossi so grateful to the crocodiles?
A．They never did harm to the Mossi.
B．They once happened to help the Mossi.
C．They led the Mossi back to their homes.
D．They provided clean drinking water for the Mossi.
B　解析：细节理解题。根据第二段的内容可知，十五世纪，在一次大旱中，摩西人外出寻找水源，跟随鳄鱼找到一个水塘。从此他们便在那里定居并把村庄叫作巴扎。这就是摩西人世代感激鳄鱼的原因。
2．What does the author intend to show in Paragraph 3?
A．The crocodile attacks cannot cause any death.
B．The villagers get along well with the crocodiles.
C．The crocodiles can bring good luck to the villagers.
D．The crocodiles can protect the villagers from danger.
B　解析：写作意图题。根据第三段的内容可知，在巴扎村，鳄鱼们死后，人们会埋葬它们并给它们举办葬礼，而且妇女在池塘边洗衣服，小孩在池塘边玩耍都没有危险，所以此段主要是想说明村民们和鳄鱼相处融洽。
3．What does the underlined word “vanish” in the last paragraph mean?
A．Move.　　　　　　　 B．Freeze.
C．Narrow. D．Disappear.
D　解析：词义猜测题。根据画线词前面说降雨量减少，后面说鳄鱼可能会带领人们找新的水源可推测，池塘可能会消失。
4．What can we infer from the last paragraph?
A．More and more tourists will visit the village.
B．The crocodiles will probably move to a new place.
C．Villagers will take measures to protect the crocodiles.
D．The crocodiles in the village are becoming less and less.
B　解析：推理判断题。根据最后一段的最后两句可推测，由于降雨量小，池塘可能会消失，所以鳄鱼有可能会搬走。

Starbucks says it uses one billion plastic straws(吸管) every year, but it plans to stop the use of plastic straws in each of its 28，000 stores across the globe. Starbucks’ announcement comes just a week after Seattle, the city where the first Starbucks opened, forbade plastic straws.
In order to replace the straws, Starbucks has developed a new lid(盖子) for some of its drinks like iced coffee and tea. Actually, the lid has a raised lip. Some people have compared the new lids to “adult sippy cups”， CNN Business reported.
Starbucks is always saying it is a company that cares much about the environment. In recent years, awareness about the effect that plastic is having on the environment—in particular, the ocean—has caused scientists to sound the alarm about a need to curb the use of plastics.
“What we realize is that these billions of little things in the ocean, such as one man’s toothbrush, one lady’s comb, all can cause the problem，” Emily Penn said. She is the co-founder of an expedition(探险队)．“But what makes us happy is that we can solve it well through our daily actions. We need billions of small actions—just little daily things to reduce the pollution.”
Customers who still want to enjoy a Starbucks drink with a straw will be able to request one, but it won’t be plastic.Instead, they will be given a straw made from paper or other eco-friendly materials.
In May, McDonald’s said it would experience a change from the use of plastic to paper straws in Ireland and the United Kingdom.The announcement from Starbucks could be a sign that more large chain restaurants will accept this kind of activity.

【解题导语】　本文是一篇夹叙夹议文。母亲问“我”身体最重要的部位是什么，“我”给出了几个答案，母亲说都不正确。爷爷去世时，母亲给了“我”答案，那就是身体最重要的部位是肩膀，因为每个人的一生中总有一些时候需要有个肩膀可以靠着哭泣。“我”最后明白了身体最重要的部位应该是无私的，它承载着对别人的痛苦的同情。
1．A.notice　　　　　　　　　　 B．believe in

恐龙，是出现在中生代时期(三叠纪，侏罗纪和白垩纪)的一类爬行动物的统称。它们主要栖息于湖岸平原(或海岸平原)上的森林或开阔地带。恐龙种类多，体形相差也大，其中最大的易碎双腔龙可能超过50米。恐龙在6 500万年前白垩纪结束的时候突然全部消失了，这成为地球生物进化史上的一个谜，而这个谜至今仍无人能解。
ANIMAL EXTINCTION①
Many animals have disappeared during the long history of the earth. The most famous of these animals are dinosaurs②. They lived on the earth tens of millions of years ago, long before③ humans came into being④ and their future seemed secure⑤ at that time. There were many different kinds of dinosaur and a number of⑥ them used to live in China． The eggs of twenty-five species have been found in Xixia County, Nanyang, Henan Province. Not long ago a rare⑦ new species of bird-like dinosaur was discovered in Chaoyang County, Liaoning Province. When scientists inspected⑧ the bones, they were surprised to⑨ find　that these dinosaurs could not only run like the others but also climb trees. They learned this from the way the bones were joined together．
◆that 引导宾语从句，作find的宾语。从句中含有not only...but also...结构。
◆the bones were joined together为省略了关系词that 或 in which 的定语从句，修饰先行词the way。
Dinosaurs died out suddenly about 65 million years ago. Some scientists think it came after an unexpected⑩ incident? when a huge rock from space hit the earth and put too much dust? into the air. Others think the earth got too hot for the dinosaurs to live on? any more. Nobody knows for sure?why and how dinosaurs disappeared from the earth in such a short time．
◆本句为主从复合句。it came after...into the air是宾语从句，作think的宾语，该宾语从句中又含有一个when引导的时间状语从句。
◆此处为why和how共同引导的宾语从句，作knows的宾语。
We know many other wild plants, animals, insects and birds have died out more recently. According to? a UN report, some? 844 animals and plants have disappeared in the last 500 years. The dodo is one of them. It lived on the Island of Mauritius and was a very friendly animal. Please listen to a story of the dodo and how it disappeared from the earth.
◆in the last 500 years 为介词短语，在句中作时间状语，相当于over/during the past 500 years，常与现在完成时连用。
动物灭绝
在地球漫长的历史中，许多动物都消失了。这些动物中最著名的就是恐龙。数千万年前，恐龙就在地球上生活，比人类的出现要早得多，那时它们的未来似乎是安全的。恐龙有许多不同的种类，其中有很多曾生活在中国。25个种类的恐龙蛋是在河南省南阳西峡县发现的。不久前，在辽宁省朝阳县发现了一种罕见的、形状像鸟的新的恐龙物种。当科学家们检查它们的骨头时，他们惊奇地发现这些恐龙不仅可以像其他恐龙一样跑，而且还可以爬树。他们是从恐龙骨头的连接方式上得知这一点的。
大约6 500 万年前，恐龙突然灭绝了。 一些科学家认为恐龙灭绝是发生在一次意外事件之后，当时太空中的一块巨石撞击地球，在空气中扬起了太多的尘土。另一些科学家则认为，地球变得太热了， 恐龙无法再(在地球上)继续生活下去了。没有人确切地知道恐龙是为什么及如何在那么短的时间内从地球上消失的。
我们知道最近有许多其他的野生植物、动物、昆虫和鸟类已经灭绝了。根据联合国的一份报告可知，在过去的500年里，大约有844种动植物已经消失了。渡渡鸟就是其中的一种。渡渡鸟生活在毛里求斯岛上，是一种非常友好的动物。请听一个关于渡渡鸟的故事，看看它是如何从地球上消失的。

A
Various animals are respected and even worshipped(崇拜)in different cultures.In Hinduism, for example, cows are valued for their gentle nature.However, in ancient Egypt, crocodiles(鳄鱼) were regarded as living representations of the god Sobek.
During the serious drought in the 15th century, the Mossi were led to an undiscovered pond by the crocodiles. This not only allowed the Mossi to survive, but also led to the founding of the village Bazoulé.
As the villagers owe their survival to the crocodiles, they now care for and live side by side with them. The villagers even bury the crocodiles and hold funerals for them after their death.The crocodiles are not only regarded as protectors of Bazoulé， but also fortune-tellers that give best wishes to the villagers. It seems that the worship of the crocodiles has paid off. For over 70 years, there has never been a death from a crocodile attack in Bazoulé.It’s normal for women to wash their clothes in the water and gather plants nearby. And it is also normal to see children playing around the water where the crocodiles live.
Naturally, this strange relationship between the villagers and crocodiles has attracted a lot of attention. Tourists from all over the world come to the village, hoping to catch sight of this unlikely bond between humans and crocodiles.Visitors have the opportunity to buy a chicken, with which they can attract the crocodiles out of the water. You can pose for pictures, and if you’re brave enough, you can sit on a crocodile’s back just like the local children usually do.
The village is trying to develop its tourism, but unfortunately, it was found to be threatened by global warming.Lower annual rainfall means that the pond will vanish one day. Perhaps the legends are true, and when this happens，the crocodiles will lead the Mossi to a new water source.
【解题导语】　本文是一篇说明文。文章主要介绍了非洲的巴扎村里凶猛的鳄鱼和人类长期和平相处，这一和谐现象吸引了无数游客慕名而来。
1．Why were the Mossi so grateful to the crocodiles?
A．They never did harm to the Mossi.
B．They once happened to help the Mossi.
C．They led the Mossi back to their homes.
D．They provided clean drinking water for the Mossi.
B　解析：细节理解题。根据第二段的内容可知，十五世纪，在一次大旱中，摩西人外出寻找水源，跟随鳄鱼找到一个水塘。从此他们便在那里定居并把村庄叫作巴扎。这就是摩西人世代感激鳄鱼的原因。
2．What does the author intend to show in Paragraph 3?
A．The crocodile attacks cannot cause any death.
B．The villagers get along well with the crocodiles.
C．The crocodiles can bring good luck to the villagers.
D．The crocodiles can protect the villagers from danger.
B　解析：写作意图题。根据第三段的内容可知，在巴扎村，鳄鱼们死后，人们会埋葬它们并给它们举办葬礼，而且妇女在池塘边洗衣服，小孩在池塘边玩耍都没有危险，所以此段主要是想说明村民们和鳄鱼相处融洽。
3．What does the underlined word “vanish” in the last paragraph mean?
A．Move.　　　　　　　 B．Freeze.
C．Narrow. D．Disappear.
D　解析：词义猜测题。根据画线词前面说降雨量减少，后面说鳄鱼可能会带领人们找新的水源可推测，池塘可能会消失。
4．What can we infer from the last paragraph?
A．More and more tourists will visit the village.
B．The crocodiles will probably move to a new place.
C．Villagers will take measures to protect the crocodiles.
D．The crocodiles in the village are becoming less and less.
B　解析：推理判断题。根据最后一段的最后两句可推测，由于降雨量小，池塘可能会消失，所以鳄鱼有可能会搬走。
B

In order to replace the straws, Starbucks has developed a new lid(盖子) for some of its drinks like iced coffee and tea. Actually, the lid has a raised lip. Some people have compared the new lids to “adult sippy cups”， CNN Business reported.
Starbucks is always saying it is a company that cares much about the environment. In recent years, awareness about the effect that plastic is having on the environment—in particular, the ocean—has caused scientists to sound the alarm about a need to curb the use of plastics.
“What we realize is that these billions of little things in the ocean, such as one man’s toothbrush, one lady’s comb, all can cause the problem，” Emily Penn said. She is the co-founder of an expedition(探险队)．“But what makes us happy is that we can solve it well through our daily actions. We need billions of small actions—just little daily things to reduce the pollution.”
Customers who still want to enjoy a Starbucks drink with a straw will be able to request one, but it won’t be plastic.Instead, they will be given a straw made from paper or other eco-friendly materials.
In May, McDonald’s said it would experience a change from the use of plastic to paper straws in Ireland and the United Kingdom.The announcement from Starbucks could be a sign that more large chain restaurants will accept this kind of activity.

【解题导语】　本文是一篇夹叙夹议文。母亲问“我”身体最重要的部位是什么，“我”给出了几个答案，母亲说都不正确。爷爷去世时，母亲给了“我”答案，那就是身体最重要的部位是肩膀，因为每个人的一生中总有一些时候需要有个肩膀可以靠着哭泣。“我”最后明白了身体最重要的部位应该是无私的，它承载着对别人的痛苦的同情。
1．A.notice　　　　　　　　　　 B．believe in
C．doubt D．guess at
D　解析：此处表示“我”一直在揣测这个问题的正确答案。notice“注意到”；believe in“相信”；doubt“怀疑”；guess at “猜测”。故答案选D。
2．A.love B．health
C．sound D．sight
C　解析：从下文“My ears”可知答案。
3．A.blind B．deaf
C．invisible D．thoughtful
B　解析：由句意可知，当“我”回答耳朵最重要时，母亲说很多人是聋哑人。
4．A.discovery B．decision
C．attempt D．suggestion

5．A.learning B．thinking
C．growing D．changing
A　解析：由“but”可知，“我”虽然学得很快，但是回答得不正确。
6．A.Before B．Till
C．Beyond D．Over
D　解析：介词over表示在一段时间内。其他选项均无此意。
7．A.ways B．things
C．questions D．times
D　解析：由上文内容以及下文“always”可知，此处表示这些年来就这个问题母亲又问了“我”几次。此处容易误选C，依据文章，这里不是表示问更多的问题，而是表示就一个问题问了好几次。
8．A.stronger B．taller
C．smarter D．nicer
C　解析：因为“我”每次回答都与以前不同，所以母亲说“我”一年比一年聪明了。句中的“but”是重要的提示词。

C．died D．got wounded
C　解析：由下文“to say our final goodbye to grandpa”可知“爷爷去世了”。

A　解析：在此之前，“我”一直以为这是“我”和母亲之间的一个游戏，没想到在这样的场合她又提出了这个问题。
13．A.worry B．puzzlement

C．disliked D．lived
D　解析：live a(n)/one’s...life意为“过着……的生活”。其他选项用在此处均不符合句意。
15．A.shoulders B．feet
C．hands D．hair
A　解析：由下文“hold up your head”可知，母亲认为人体最重要的部位是肩膀。

17．A.respect B．favor

Passenger pigeons(旅鸽) were the most common birds in all of North America in the 1800s.It was common to see large groups of passenger pigeons—groups that made a sound like a storm.But today，they are extinct because of human behavior.Now，some scientists want to bring passenger pigeons back to life by using new technology and scientific ideas.They call this process de-extinction.
De-extinction has not happened yet.It is still just an idea.The process of de-extinction is not easy.First，scientists must collect DNA from the bodies of extinct animals.Then they will put it in the eggs of similar animal species.When these animals become adults，they will have babies.And these baby animals will have the DNA of the extinct animals.
Scientists believe it is possible to bring back passenger pigeons and many other animals.However，not everyone thinks this is a good idea.
Stuart Primm is the world’s leading expert on modern animal extinction.He believes that bringing extinct animals back to life is bad for the earth.On one hand, these animals no longer have a safe place to live.On the other hand, they could cause other animals to die.
Many other scientists do not agree with Stuart Primm.Stuart Brand，a writer and scientist，is one of them.He believes de-extinction is good for many reasons.
“The current generation(当代) of children will experience the return of some unusual animals in their lifetime.It may be part of what defines their generation and their attitude to the natural world.They will take their parents to zoos to see the growing populations of passenger pigeons, and maybe even dodo birds.This will provide a good deal of money for zoos busy with extinct species restoration(恢复). Humans killed off a lot of species over the last 10，000 years. So, it’s right to bring some back to life，” he said.

4．How does Stuart Brand feel about de-extinction?
A．Wrong.　　　　　　　　　 B．Difficult.
C．Important. D．Wasteful.

How many times do you wish you had time to pick up a new hobby or skill? Often, you hope to learn something new, but you may never get started. 1.________ Many people have such plans, but they just don’t get started. The common reason is that they feel they don’t have enough time.
Hobbies provide a number of important benefits(益处). They provide us with a break from work. 2.________ Many hobbies, such as group sports and book clubs, allow us to make new friends. Because of such hobbies, we have a social life outside of our families and classrooms.
So we’ve covered why hobbies are important, but how can we make time? First, find out what you can cut back on. Chances are that you don’t want to skip doing the laundry or helping your kids with homework. 3.________ Do you spend your weekends on the couch? Chances are that there’s more time than you think.
4．________ It may not sound relaxing for your free time to be on a schedule, but you’ll be glad that you set aside time for your hobby once you’re on a regular schedule. Otherwise, it’s too easy to put it off.
5．________ Much of the difficulty in doing something lies in getting started. Even if you don’t feel like it, or you have other things to do, get up and use the time you’ve scheduled. If your hobby is something you love, it won’t be long before you find yourself actually having fun!

1．were found　解析：考查一般过去时的被动语态。设空处所在句意为“一百多年前，从美国的西南部到南美的阿根廷都能发现美洲豹的踪影”，故find与jaguars之间是被动关系，应用被动语态，且由A hundred years ago可知，此处应用一般过去时，故填were found。
2．natural　解析：考查形容词作定语的用法。设空处作定语修饰habitat，表示“自然的”，故填形容词natural。
3．mostly　解析：考查副词。设空处作状语修饰谓语动词live，表示“主要地”，故填副词mostly。
4．to　解析：考查介词。according to意为“按照，根据……所说”。
5．is　解析：考查主谓一致。设空处所在句描述现在的情况，应用一般现在时，因为主语是habitat loss，故填is。
6．scientists　解析：考查名词的数。设空处作主语，表示“科学家”，因为scientist是可数名词，由Most及谓语动词agree可知，此处应填scientists。
7．an　解析：考查不定冠词。设空处所在句意为“树木在气候变化方面起着重要作用”，又因important的发音以元音音素开头，故填an。play an important role in...意为“在……方面起重要作用”。
8．trapped　解析：考查过去分词作表语的用法。设空处所在句意为“森林面积的减少意味着越来越多的温室气体停留在大气层里”，trap与greenhouse gases之间是被动关系，故填过去分词trapped。
9．have disappeared　解析：考查现在完成时。由since a hundred years ago可知，此处应用现在完成时，因为主语是half of the world’s wetlands，故填have disappeared。
10．or　解析：考查连词。either...or...意为“或者……或者……”。

Dear__Editor，
Here I write to tell you about my experience in the zoo last Sunday. I feel terribly sorry and ashamed of what people did to the animals.
It seemed that they were not being treated well. I saw many visitors throw stones at them.Some people just looked and laughed, but no one thought those actions were wrong.
I think it’s time that we should do something. First, we should make people know animals are our friends. Second, anyone who treats animals badly should be fined.
I hope you can help educate people to love and respect animals. Thank you.

Dear Sir/Madam，
I’m writing to express my opinion on how to protect the animals on the island I visited last weekend. The animals there are lovely, but it’s said that the number of them is decreasing year by year. If measures aren’t taken, they will be in danger of extinction.
As far as I’m concerned, laws concerning animals protection should be made to punish those illegal hunters. Besides, it is necessary to set up natural reserves. There is no doubt that animals living in safe environments are more likely to survive. What’s more, something should be done to raise people’s awareness of protecting animals.
To sum up, protecting animals is of great urgency and it is vital for us to take steps to protect them.
Please help the poor animals. I am sure that they will survive with your help.

Dear_Henry，
I’m very pleased to receive your e-mail. It’s my great pleasure to offer you some suggestions on your visit to Chinese friends.
To begin with, you are supposed to arrive early, which shows you attach much importance to the visit. With regard to the presents, a box of local chocolates may be a good choice. You can also bring them a bottle of wine produced in England. What’s more, it’s necessary for you to know some table manners. For instance, you can’t start to eat before the most respected or the elderly begin. Anyway, please take it easy. I believe your friends will forgive you even if you don’t do well.
I would highly appreciate your consideration of my suggestions.
Best，
Li_Hua

Passenger pigeons(旅鸽) were the most common birds in all of North America in the 1800s.It was common to see large groups of passenger pigeons—groups that made a sound like a storm.But today，they are extinct because of human behavior.Now，some scientists want to bring passenger pigeons back to life by using new technology and scientific ideas.They call this process de-extinction.
De-extinction has not happened yet.It is still just an idea.The process of de-extinction is not easy.First，scientists must collect DNA from the bodies of extinct animals.Then they will put it in the eggs of similar animal species.When these animals become adults，they will have babies.And these baby animals will have the DNA of the extinct animals.
Scientists believe it is possible to bring back passenger pigeons and many other animals.However，not everyone thinks this is a good idea.
Stuart Primm is the world’s leading expert on modern animal extinction.He believes that bringing extinct animals back to life is bad for the earth.On one hand, these animals no longer have a safe place to live.On the other hand, they could cause other animals to die.
Many other scientists do not agree with Stuart Primm.Stuart Brand，a writer and scientist，is one of them.He believes de-extinction is good for many reasons.
“The current generation(当代) of children will experience the return of some unusual animals in their lifetime.It may be part of what defines their generation and their attitude to the natural world.They will take their parents to zoos to see the growing populations of passenger pigeons, and maybe even dodo birds.This will provide a good deal of money for zoos busy with extinct species restoration(恢复). Humans killed off a lot of species over the last 10，000 years. So, it’s right to bring some back to life，” he said.

How many times do you wish you had time to pick up a new hobby or skill? Often, you hope to learn something new, but you may never get started. 1.________ Many people have such plans, but they just don’t get started. The common reason is that they feel they don’t have enough time.
Hobbies provide a number of important benefits(益处). They provide us with a break from work. 2.________ Many hobbies, such as group sports and book clubs, allow us to make new friends. Because of such hobbies, we have a social life outside of our families and classrooms.
So we’ve covered why hobbies are important, but how can we make time? First, find out what you can cut back on. Chances are that you don’t want to skip doing the laundry or helping your kids with homework. 3.________ Do you spend your weekends on the couch? Chances are that there’s more time than you think.
4．________ It may not sound relaxing for your free time to be on a schedule, but you’ll be glad that you set aside time for your hobby once you’re on a regular schedule. Otherwise, it’s too easy to put it off.
5．________ Much of the difficulty in doing something lies in getting started. Even if you don’t feel like it, or you have other things to do, get up and use the time you’ve scheduled. If your hobby is something you love, it won’t be long before you find yourself actually having fun!
A．Actually, you’re not alone.
B．Finally, get up and truly do it!
C．Second, try your best not to put it off.
D．But how much time do you spend watching TV?

1．A　解析：根据下一句 Many people have such plans, but they just don’t get started. 可知，这里是指“你”不是唯一一个这样做的人。
2．G　解析：根据第二段中的 Hobbies provide a number of important benefits(益处). 以及后文的信息可知，这里是在列举有兴趣爱好的好处，故选G项。
3．D　解析：根据上文的 Chances are that you don’t want to skip doing the laundry or helping your kids with homework. 以及后文信息可知，我们虽然无法避开洗衣服和给孩子辅导功课的时间，但我们可以抽出看电视的时间。
4．E　解析：根据第四段中的 It may not sound relaxing ... on a schedule, but you’ll be glad that ... once you’re on a regular schedule. 可知，这里是建议我们给新的兴趣爱好安排出时间。
5．B　解析：根据下文的 Much of the difficulty in doing something lies in getting started. 可知，作者在本段主要鼓励我们要行动起来，故选B项。

The jaguar(美洲豹) is the largest cat in the Americas. A hundred years ago, jaguars 1.____________(find) everywhere from the southwestern United States to Argentina, in South America. Today, jaguars are an endangered species throughout their 2.____________(nature) habitat and have been lost from 50 percent of their territory(领土).

Trees also play 7.____________ important role in climate change. Fewer forests mean that more greenhouse gases remain 8.____________(trap) in the atmosphere, the mixture of gases that surrounds the Earth.

That means less space for animals to feed and raise their young.
1．were found　解析：考查一般过去时的被动语态。设空处所在句意为“一百多年前，从美国的西南部到南美的阿根廷都能发现美洲豹的踪影”，故find与jaguars之间是被动关系，应用被动语态，且由A hundred years ago可知，此处应用一般过去时，故填were found。
2．natural　解析：考查形容词作定语的用法。设空处作定语修饰habitat，表示“自然的”，故填形容词natural。
3．mostly　解析：考查副词。设空处作状语修饰谓语动词live，表示“主要地”，故填副词mostly。
4．to　解析：考查介词。according to意为“按照，根据……所说”。
5．is　解析：考查主谓一致。设空处所在句描述现在的情况，应用一般现在时，因为主语是habitat loss，故填is。
6．scientists　解析：考查名词的数。设空处作主语，表示“科学家”，因为scientist是可数名词，由Most及谓语动词agree可知，此处应填scientists。
7．an　解析：考查不定冠词。设空处所在句意为“树木在气候变化方面起着重要作用”，又因important的发音以元音音素开头，故填an。play an important role in...意为“在……方面起重要作用”。
8．trapped　解析：考查过去分词作表语的用法。设空处所在句意为“森林面积的减少意味着越来越多的温室气体停留在大气层里”，trap与greenhouse gases之间是被动关系，故填过去分词trapped。
9．have disappeared　解析：考查现在完成时。由since a hundred years ago可知，此处应用现在完成时，因为主语是half of the world’s wetlands，故填have disappeared。
10．or　解析：考查连词。either...or...意为“或者……或者……”。

Dear__Editor，
Here I write to tell you about my experience in the zoo last Sunday. I feel terribly sorry and ashamed of what people did to the animals.
It seemed that they were not being treated well. I saw many visitors throw stones at them.Some people just looked and laughed, but no one thought those actions were wrong.
I think it’s time that we should do something. First, we should make people know animals are our friends. Second, anyone who treats animals badly should be fined.
I hope you can help educate people to love and respect animals. Thank you.
Yours__sincerely，
Li__Hua
