Ladies and gentlemen, I returned to this year in a time machine.In the year 2500，we are able to travel through time to any year in the history of the earth.This year is your last chance to change your lifestyle to save the earth.
Beginning in the middle of the 20th century, a few people were worried about polluting the earth's water and air, but most people did not change their way of life.Instead, they continued to pour dangerous chemicals and other waste into lakes and seas, to drive more and more cars and trucks, and to cut down trees.
By the year 2200, the earth's water was completely polluted.People could no longer drink water, and they had to use other types of liquids.
So, by the year 2300, there were so many people that food became scarce.There was no water to grow food and all of the fish in the lakes and seas died because of pollution.Terrible wars broke out between the rich and the poor.Scientists were working very hard to find another planet in space where humans could live.
By the year 2400, the air was too polluted for humans to breathe.So we had to leave earth.But only the rich were able to leave.Where did we go Nowhere.The scientists did not find another safe planet, so now we must travel around the universe in our spaceships.We are still looking for a place to call our home.
So, it is up to you to change history.There is still hope.You must change your lifestyle now, before it is too late.
语篇解读：本文是一篇记叙文。文章从未来的角度指出人们如果不改变生活方式，地球在未来几百年将发生巨变。
1．Which problem is NOT talked about in Paragraph 2
A．Water. B．Air.

2．What's the meaning of “scarce” in Paragraph 4

B．There wasn't enough food for people to eat by the year 2200.

C．Look for New Home D．Return to the Earth
解析：选B 标题归纳题。整篇短文都是围绕“change your lifestyle to save the earth”这个话题展开的，故选B项。

Not all heroes wear capes — some wear hiking boots and work in America's national parks.

Lexie and her fellow hikers met a man whose dog was__2__ ill because of spending too much time in hot sunshine.Even though they__3__their water, the group was__4__that it wouldn't be enough to save the pup, after seeing how much the dog was__5__.Too tired to carry the dog himself，the__6__owner called the park rangers (公园管理员) quickly, and reported their__7__on Mount Tammany.

When she got home，Lexie posted the__12__deed on the Internet and it spread with 35,000 people sharing the post and showing__13__for the ranger.
“This is a HERO，” Lexie wrote.“We are so__14__to have rangers like this who put even animals before themselves.This ranger__15__recognition for his bravery, selflessness, and strength.”
语篇解读：本文是一篇记叙文，主要讲述了一名男子的爱犬因为高温面临生命危险，于是这名男子向公园管理员求助，并在管理员的热心帮助下挽救了狗的生命。
1．A.reported B．stated
C．witnessed D．changed
解析：选C 根据第三段可知，Lexie和她的朋友遇到了一个男子，他的爱犬出现了问题；再根据下文管理员救狗的情节和Lexie回家后将事件发布在网上可知，当事件发生时她和她的朋友在场，目睹(witnessed)了这一善举。
2．A.slightly B．severely
C．casually D．hardly
解析：选B 由第二段中的“The temperature was rising to 90 degrees”及下文救狗的内容可知，它当时病得很严重。severely“严重地”；slightly“略微，稍微”；casually“不经意地”；hardly“几乎没有”。
3．A.bought B．threw
C．desired D．donated
解析：选D 根据下文“to save the pup”可知，为了救中暑的狗，Lexie和她的朋友把水赠送给了狗。donate“赠送”；desire“渴望”。
4．A.sorry B．afraid
C．ashamed D．glad
解析：选B 下文提到狗主人向公园管理员求助，由此可以推测出作者一行人送出去的水是不够的，因此不免会担心(afraid)。
5．A.sweating B．hurting
C．struggling D．starving
解析：选C 根据空前的“it wouldn't be enough to save the pup, after seeing how much the dog was”之间的因果关系可以推知，正是因为看到狗在挣扎，所以他们才担心这些水不够救狗，故“struggling”(挣扎)符合语境。sweat“流汗”；hurt“感到疼痛”；starve“挨饿”。
6．A.loving B．strong
C．unwilling D．generous
解析：选A 根据上文中的“Too tired to carry the dog himself”以及下文中的“called the park rangers (公园管理员) quickly”可知，这位主人一直在想办法挽救自己的爱犬，这说明他是一位有爱心的(loving)主人。generous“慷慨的”。
7．A.temperature B．wish
C．request D．location
解析：选D 狗主人联系了管理员，根据常识可知，如果想及时获救的话，就要告诉管理员他们所在的位置(location)。
8．A.found B．saved
C．took D．followed
解析：选A 根据后一句“Kris then lifted the huge dog onto his shoulders ...down the mountain”可知，管理员很快在山上发现了他们，然后把狗背下山进行救助，故此处found符合语境。
9．A.pushing B．asking
C．ordering D．carrying
解析：选D 参见上题解析。
10．A.center B．bottom
C．stream D．forest
解析：选C 由后面的“Kris laid him in the water”可以推知，他们走到了一条小河(stream)边。
11．A.had B．poured
C．held D．sneezed
解析：选B 在中暑的情况下，为了给狗降温，Kris把河里的水泼(poured)在狗的身上。pour“倾倒”；sneeze“打喷嚏”。
12．A.fair B．strange
C．familiar D．good
解析：选D 公园的管理员在天气炎热的情况下救助一只狗，这当然是一种非常好的行为。所以此处是说当Lexie回到家时，她把这一善举(good deed)发布在网上。
13．A.surprise B．admiration
C．mercy D．understanding
解析：选B 根据空前的“it spread with 35,000 people sharing the post”可知，这个帖子在网上快速传播，这也说明大家都对这个管理员表示敬佩(admiration)。surprise“惊讶，意外”；mercy“仁慈，宽恕”；understanding“理解，领悟”。
14．A.lucky B．poor
C．brave D．cool
解析：选A 此处是Lexie在帖子中对管理员救狗行为的评价，根据下文“put even animals before themselves”可知，能有这样的管理员，Lexie认为他们很幸运(lucky)。
15．A.requires B．demands
C．deserves D．reflects
解析：选C 根据空后的“recognition for his bravery, selflessness, and strength”可知，此处是说这位勇敢、无私、强大的管理员值得(deserves)大家的认可。require“要求”；demand“要求”； reflect“反映，表明”。

语篇解读：本文是一篇记叙文。作者在家乡的山里一边开车，一边欣赏秋天的景色，这时遇上了一头雌鹿和它的小鹿。作者等待它们安全离开后才继续行驶。
1．Driving 考查非谓语动词。此处为动名词短语作主语。
2．leaves 考查名词复数。leaf是可数名词，此处应用复数形式。
3．had become 考查时态。开车经过是发生在过去的事情，此处指过去的过去，所以用过去完成时态。
4．a 考查冠词。此处为泛指，所以用不定冠词。
5．Knowing 考查非谓语动词。know和逻辑主语I之间是主动关系，故用现在分词形式。
6．frightened 考查形容词。frightened意为“害怕的”。
7．them 考查代词。指代鹿妈妈和幼鹿。
8．safe 考查形容词。keep sb./sth.safe意为“保持某人或某物的安全”，此处用形容词safe作宾语补足语。
9．that 考查固定句型。It seems/seemed that ...意为“看来……”。
10．largely 考查副词。此处用副词修饰动词left。UNIT 2 课时跟踪检测（二） 语言运用综合练

Ⅰ.阅读理解
The world's tiger population has reduced in the last century.Today, fewer than 4,500 survive in the wild.But India is now home to 2,226 tigers in the wild.That's up from the 1,706 counted in the country's 2010 tiger survey.
“While the tiger population is plunging in the world, it is rising in India，” says India's Minister for Environment and Forests.“We have increased by 30 percent from the last count.That is a huge success story.”
India does a wild tiger count every four years.The 2014 survey was conducted using nearly 10,000 cameras placed throughout India's wildlife reserves and other tiger puter software sorted through the images to discover each tiger by its unique pattern of stripes.Nearly 80 percent of all the tigers counted were recognized this way.“The information is as correct as you can get，” says Belinda Wright.“So it's very good news for the tigers.”
Even so, the tiger remains one of the world's most endangered animals.At the start of the 20th century, about 100,000 tigers lived in the wild, and their natural habitat enlarged through much of Asia.About 93 percent of their habitat has been lost, mostly to human development.
Another major threat to the tiger's survival is poaching.Tiger tails, bones, eyes, and other body parts are still prized in Asia.India is an important member in an international effort known as Tx2 — a program that aims to double the worldwide number of tigers in the wild.
India takes that goal seriously.The government has set aside more than 40 tiger reserves — areas that are protected from poachers and development.
“It is heartening that India's tiger numbers are increasing，” the environment minister says.“This was not the situation a decade ago, and I am proud that we have risen to the challenge and turned the situation around.”
语篇解读：本文是一篇说明文。印度政府采取措施，积极拯救野生老虎，最终使得它们的数量显著增加。
1．The underlined word “plunging” may mean “________”．
A．limiting B．calculating
C．balancing D．decreasing
解析：选D 词义猜测题。根据第二段中的“While”及画线词后面的“it is rising in India”可知，这里的plunging表示与rising相反的意思，即“减少”。
2．We can infer from the third paragraph that________.
A．every tiger has its own special patterns of stripes
B．all Indian tigers are identified by software
C．India takes photos of tigers every four years
D．tigers are born with stripes in similar patterns
解析：选A 推理判断题。结合第三段的“Computer software sorted through the images to discover each tiger by its unique pattern of stripes.”可知，每个老虎身上的条纹是独特的。
3．What situation does Indians turn around
A．The tiger reserves have been damaged.
B．The number of tigers is reducing.
C．The hunting of tigers is illegal.
D．The habitats of tigers are enlarging.
解析：选B 细节理解题。从最后一段的“This was not the situation a decade ago, and I am proud that we have risen to the challenge and turned the situation around.”可知，印度已经扭转了老虎数量下降的情形。
4．What is the passage mainly about
A．Indian tigers are on the way back to their habitats.

Dear WWF，
There are wetlands in my hometown called Wucheng Town, on the lakeside of the Poyang Lake.When winter comes, many birds from the north fly to live here, including some rare and endangered ones, which adds a beautiful view to my hometown.However, the harm to the birds is various.Eggs are often picked up.Worse still, people even catch birds for meat.Pollution from chemical factories is also a big problem.Now the area of wetland is decreasing and fewer birds arrive here each year!
I strongly hope that our government should take effective measures to protect these migratory birds so that we can see a beautiful picture of the peaceful coexistence of human beings and birds.
Yours sincerely，

“No! Please wait for me.I want to go to the zoo，”Emma cried.“I'm sorry, Emma.I've told you a dozen times to clean your room and you ignored me.You can't find your shoe now.It's your own fault for not doing as I asked.You will stay home.”
Emma ran into her bedroom, crying.Her mom came to the door and said，“Emma，clean that room of yours before I get home.I've told grandma not to give you any sweets until you finish the work.” She went out to the car with Ryan and Emma's dad and then they drove away.

When scientists go to a forest to study monkeys and their habits and behaviors, how do they know who's who
In the past, scientists had to make marks on each of the animals to distinguish them. But in the future, they may have a much easier way to tell them apart thanks to facial recognition technology.
A research team from China's Northwest University is using facial recognition technology to identify thousands of snub nosed monkeys that live on Qinling Mountain in Shaanxi Province.
Similar to human facial recognition, the technology that is used to identify monkeys uses their facial features to create a database that includes every monkey, Xinhua reported. “When the system is fully developed, we can connect it with cameras set up in the mountains. The system will automatically recognize the monkeys, name them and analyze their behavior，” said Zhang He, a member of the research team. “For each snub nosed monkey, we have 700 to 800 image samples, and the recognition success rate is 94 percent，” Zhang added.
“We used mobile phones and portable cameras with the monkeys in tests at distances ranging from about 3 to 10 meters，” said He Gang, a member of the research team and an associate professor in the College of Life Sciences at Northwest University. “There is no need to interfere with the monkeys. Such a method of sampling is clearly non invasive.”
Compared to humans, facial recognition technology for monkeys is more complicated because of their hairier faces. The color of their hair causes them to blend into their environment. These_factors make it harder for computers to identify them.
“Monkeys do not cooperate with researchers in the same way humans do. It is difficult to take high quality pictures and videos of them, which are needed to improve the system，” said Li Baoguo, leader of the research team.
Currently, there are about 4,000 snub nosed monkeys living on Qinling Mountain. The team's goal is to successfully identify every monkey that lives there.
语篇解读：本文是一篇说明文。文章主要介绍了一项区分猴子的新技术——猴脸识别技术。文章也介绍了这种技术的工作原理以及优势。
1．What problem do scientists face while studying monkeys according to the text
A．How to mark them.

When scientists go to a forest to study monkeys and their habits and behaviors, how do they know who's who
In the past, scientists had to make marks on each of the animals to distinguish them. But in the future, they may have a much easier way to tell them apart thanks to facial recognition technology.
A research team from China's Northwest University is using facial recognition technology to identify thousands of snub nosed monkeys that live on Qinling Mountain in Shaanxi Province.
Similar to human facial recognition, the technology that is used to identify monkeys uses their facial features to create a database that includes every monkey, Xinhua reported. “When the system is fully developed, we can connect it with cameras set up in the mountains. The system will automatically recognize the monkeys, name them and analyze their behavior，” said Zhang He, a member of the research team. “For each snub nosed monkey, we have 700 to 800 image samples, and the recognition success rate is 94 percent，” Zhang added.
“We used mobile phones and portable cameras with the monkeys in tests at distances ranging from about 3 to 10 meters，” said He Gang, a member of the research team and an associate professor in the College of Life Sciences at Northwest University. “There is no need to interfere with the monkeys. Such a method of sampling is clearly non invasive.”
Compared to humans, facial recognition technology for monkeys is more complicated because of their hairier faces. The color of their hair causes them to blend into their environment. These_factors make it harder for computers to identify them.
“Monkeys do not cooperate with researchers in the same way humans do. It is difficult to take high quality pictures and videos of them, which are needed to improve the system，” said Li Baoguo, leader of the research team.
Currently, there are about 4,000 snub nosed monkeys living on Qinling Mountain. The team's goal is to successfully identify every monkey that lives there.

Jaylynn Thorpe, 3，wandered away from his baby sitter at 4 pm Friday and was missing for 21 hours as hundreds of friends, family members and officials searched for him in the thick woods of Halifax County, fearing the_worst.
“The only thing we wanted to do was just keep searching until we found him，”Halifax County Sheriff Stanley Noblin told reporters.
“We didn't forget the issue that 17 degrees was almost unbearable，” said his father, James Thorpe.
Officials said the lost little boy and the two family puppies wandered up to a mile in the dark, even across a highway, but it wasn't until Saturday afternoon that members of the search team found him sitting by a tree, the two puppies nestled (依偎) against him.
The little boy didn't say anything, according to the rescue team member Jerry Gentry, but instead just opened his arms up like, “I'm ready to go.”
“When I first saw him, he was like, ‘Momma, I got cold.I slept in the woods last night.The puppies kept me warm.’He told me that the dogs slept up against him.And I'm sure their body heat kept him warm，” said his mother, Sarah Ingram.
As the child was placed in an ambulance to be taken to a local hospital for examination, the puppies were watching where he went.
As word went out that the child was alive and well, family members cheered and cried for joy.
Close to 300 people from North Carolina and Virginia joined in the search to find Jaylynn.
The boy spent Saturday night under observation at Halifax Regional Hospital and ate a double cheeseburger, a hot dog, strawberry ice cream and French fries.
Meanwhile, the furry heroes, their tails wagging, were rewarded with food.

Scientists in Australia thought they had developed a new tracker that cost dear and would not cause flying problems to help them monitor magpies (喜鹊), who are known to be quite clever and live in groups of up to 12 birds and work together to defend the area they live in, but these birds had other ideas.
The team equipped five magpies with small backpack like harnesses attached to the trackers, each of which weighed less than one gram. Once the trackers were on, scientists could guide the birds that previously received their instructions back to an outdoor ground “feeding station” where the trackers could charge wirelessly, and the team could download the data.
Scientists planned the pilot experiment to learn more about how far the highly intelligent creatures travel and if they have any patterns or schedules of travelling. The scientists are concerned that magpies may have a hard time adjusting as the world warms up because of climate change.
However, within ten minutes of placing the tracker on the fifth experiment, one clever female magpie without a tracker began picking at the harness of another younger bird. Finally, the female bird succeeded, and the behavior was repeated in the following hours. By day three of the experiment, none of the birds had trackers anymore. “The birds beat us，” said Dominique Potvin, one of the scientists.
The team didn't get the data they wanted, but they realized that the magpies had taught them an unexpected lesson that magpies are able and willing to help each other out, even if the bird that is helping doesn't get a reward. This is called “rescue behavior”， which is not that common in the animal world, especially among birds. The scientists think this is the first time rescue behavior has been reported for Australian magpies.
The scientists are glad they've learned about the fact. But now they need to try again to figure out a good way to track these clever birds to get what they really want.
语篇解读：本文是一篇说明文。文章主要介绍了澳大利亚科学家原本利用追踪器了解喜鹊的运动习性，但是却无意中发现了喜鹊的“合作救援”行为。

IKEA's research lab Space 10 has offered an open source design that allows everyone to build a bee home.
“For almost 80 years, IKEA has enabled people to create a better everyday life at home，” said Space 10 director Kaave Pour.“But our home is more than just four walls — our home is also the planet we live on.We want to make people everywhere help protect these tiny insects and rebalance our relationship with the planet.”
Space 10 designed the home mainly for solitary (独居的) bees, as they are important for pollination (授粉)— a single solitary bee provides as much pollination as 120 honeybees.These bees, however, are under threat of extinction.“Solitary bees are friendly，” said Space 10.“They don't produce honey, so they have nothing to protect, which makes them great guests that can easily be around your kids and pets.”
The Bee Home project makes use of digital fabrication (制造) technology to offer users a design process.First, the user chooses the size, height and style of his bee home on the Bee Home website, as well as where he will put his home — on a rooftop or in a garden.Then the design is completed, and the user can download the design for free, before finding the local maker space where he can have the bee home made on demand.The final step is to collect the bee home and place it in one's favorite place.He can also plant some flowers around it to provide the best environment for the yellow and black bees.Once placed, the bee home should be largely left untouched, aside from a quick cleaning every third year.
“It is important to me that the bee home should look amazing and it almost feels like you've added a piece of artwork to your garden or your rooftop，” says Klein, who is based in Copenhagen.“The project really shows how design can be good for both people and their environment.”

Scientists in Australia thought they had developed a new tracker that cost dear and would not cause flying problems to help them monitor magpies (喜鹊), who are known to be quite clever and live in groups of up to 12 birds and work together to defend the area they live in, but these birds had other ideas.
The team equipped five magpies with small backpack like harnesses attached to the trackers, each of which weighed less than one gram. Once the trackers were on, scientists could guide the birds that previously received their instructions back to an outdoor ground “feeding station” where the trackers could charge wirelessly, and the team could download the data.
Scientists planned the pilot experiment to learn more about how far the highly intelligent creatures travel and if they have any patterns or schedules of travelling. The scientists are concerned that magpies may have a hard time adjusting as the world warms up because of climate change.
However, within ten minutes of placing the tracker on the fifth experiment, one clever female magpie without a tracker began picking at the harness of another younger bird. Finally, the female bird succeeded, and the behavior was repeated in the following hours. By day three of the experiment, none of the birds had trackers anymore. “The birds beat us，” said Dominique Potvin, one of the scientists.
The team didn't get the data they wanted, but they realized that the magpies had taught them an unexpected lesson that magpies are able and willing to help each other out, even if the bird that is helping doesn't get a reward. This is called “rescue behavior”， which is not that common in the animal world, especially among birds. The scientists think this is the first time rescue behavior has been reported for Australian magpies.
The scientists are glad they've learned about the fact. But now they need to try again to figure out a good way to track these clever birds to get what they really want.

IKEA's research lab Space 10 has offered an open source design that allows everyone to build a bee home.
“For almost 80 years, IKEA has enabled people to create a better everyday life at home，” said Space 10 director Kaave Pour.“But our home is more than just four walls — our home is also the planet we live on.We want to make people everywhere help protect these tiny insects and rebalance our relationship with the planet.”
Space 10 designed the home mainly for solitary (独居的) bees, as they are important for pollination (授粉)— a single solitary bee provides as much pollination as 120 honeybees.These bees, however, are under threat of extinction.“Solitary bees are friendly，” said Space 10.“They don't produce honey, so they have nothing to protect, which makes them great guests that can easily be around your kids and pets.”
The Bee Home project makes use of digital fabrication (制造) technology to offer users a design process.First, the user chooses the size, height and style of his bee home on the Bee Home website, as well as where he will put his home — on a rooftop or in a garden.Then the design is completed, and the user can download the design for free, before finding the local maker space where he can have the bee home made on demand.The final step is to collect the bee home and place it in one's favorite place.He can also plant some flowers around it to provide the best environment for the yellow and black bees.Once placed, the bee home should be largely left untouched, aside from a quick cleaning every third year.
“It is important to me that the bee home should look amazing and it almost feels like you've added a piece of artwork to your garden or your rooftop，” says Klein, who is based in Copenhagen.“The project really shows how design can be good for both people and their environment.”
9．What is the purpose of IKEA's Bee Home project

A．The main causes of solitary bees' extinction.
B．The difference between solitary bees and honeybees.
C．The reason for designing homes for solitary bees.
D．The need for improving humans' relationship with bees.
11．What can we learn about the bee home
A．Its color is yellow.
B．It is designed by its user.
C．It needs to be cleaned every year.
D．It can be ordered on the Internet.
12．What does Klein care about when choosing a bee home
A．Whether it is beautiful.

Endangered species are animals that are on their way to becoming extinct.Some of the reasons why animals become endangered are caused by humans.__1__Forests and grasslands are being destroyed for farmland.Pollution is another leading cause of endangered animals.Air, water, and land pollution can harm animals by destroying their living environment.__2__For example, the arrival of new animal species in an area can endanger wild animals.All the reasons above have caused more and more animals to become endangered.So we should take action to help them.Here are some useful ways.
First, plant trees.Trees recycle oxygen, returning it to the air for us to breathe.__3__
Second，pick up trash.Picking up trash not only protects the environment and keeps our surroundings beautiful, but it can also save wild animals by giving them a safer and cleaner environment.__4__
__5__The population increase threatens the wildlife as our resources become fewer and fewer，which influences wild animals' living environment greatly.So keep an eye on the latest news about endangered animals and reach out our hands！By contributing money, things or just volunteering, we will play a valuable role in the protection of wildlife and in helping our earth!
A．Third, donate something.
B．One reason is the loss of habitat.
C．The third reason is the arrival of new animal species.
D．Third，learn about the latest information about wild animals.
E．They also help to create a complete and lively global ecosystem.
F．So pick up as much trash as we can to help protect wild animals.
G．Here are other causes of endangered species that are indirectly caused by humans.
