A
Asda Living, a superstore in Cheetham Hill, Manchester is introducing a “quiet hour” to help autistic (孤独症的) and other disabled shoppers. It will turn off the in?store music and TVs to make the shop perfect for anyone who is troubled by loud noises.
Manager Simon Lea says “you'll be able to hear a pin (大头针) drop” when he starts his first quiet hour at 8 am on Saturday May 7.
He decided to introduce it after seeing a boy with autism crying on the shop floor two weeks ago.
“This boy was kicking and shouting. His mum just didn't know what to do. She told me he has autism，” said Simon, a 39?year?old father of two. “Then I gave him a￡1 football. This boy looked at me and he started playing with the football.”
Because of the event, the manager decided to talk to a member of staff (员工) with an autistic child and disabled shoppers to see if he could do anything for them.
The result is the “quiet hour”， which will mean staff coming in an hour early at 6 am to prepare the shop for the May 7 event.
“It's all about helping people really. Six months ago I would have said ‘control your child’ even though I've got children. But learning about autistic and other disabled people has helped me think about how I can make it a better place to shop，” said Simon. “I myself suffered for many years with anxiety (焦虑). I used to hate going into busy stores. There are a lot of people who have mental illness and we want to make the shop better for them.”

What do you usually do when a flying insect lands on your arm? Most likely you blow it away. But what if that bug were a ladybug (瓢虫)? Then chances are you would let it stay. What is it about ladybugs that we like?
Farmers once thought ladybugs were a good luck sign. A ladybug in the field meant that the crops (庄稼) would be successful and the weather would be good. The farmers may have been exaggerating (夸大) about what a very small bug can do, but in fact ladybugs do help out with the crops. They eat harmful insects.
Actually, it is not the adult ladybug that eats the other insects. It's the ladybug larvae (幼虫). Ladybugs lay their eggs on leaves that are covered with aphids or other insects. When the larvae come out of the eggs, they are very hungry and will eat mites, aphids, mealybugs, green flies, and other crop?destroyers.
A single ladybug larva can eat over 1,000 aphids in one day. In the 1800s, ladybugs were brought all the way from Australia to California and set free among orange trees that were dying from being eaten by insects. The little red and black “eating machines” completely saved all the trees.
Ladybugs go about their daily business without worrying much about anything. Very few birds or insects will eat a ladybug because it gives off something that is dangerous to eat. Ladybugs also protect themselves by playing dead.They fall off leaves and remain very still until their enemy goes away.
So next time you see a ladybug, think about what it may be up to. Maybe it is off to save an orange tree. Maybe its next move will be to fall off a leaf and play dead or stand_up_to a bird about 100 times its size. Maybe it's letting you know that the weather will be good tomorrow. Who knows? Ladybugs are special that way.
【读篇解读】 本文是说明文。文章是对瓢虫的介绍。
5．What do we know about mites and aphids?
A．They do harm to the crops.
B．They eat more than they should.
C．They are food for adult ladybugs.
D．They are the enemy of ladybug larvae.
答案与解析：A 推理判断题。由第三段中的“mites, aphids, mealybugs, green flies, and other crop?destroyers”可知，这些都是对庄稼有害的虫子。
6．Why were ladybugs brought from Australia to California in the 1800s?
A．To report the weather for farmers.
B．To increase their number.
C．To do research on them.
D．To save orange trees.
答案与解析：D 细节理解题。由第四段中的“ladybugs... set free among orange trees that were dying from being eaten by insects”可知，十九世纪瓢虫被从澳大利亚带到加利福尼亚州是为了挽救被害虫侵害的橘子树。
7．What does the underlined part “stand up to” in the last paragraph probably mean?
A．Play with. B．Worry about.
C．Get along with. D．Fight back against.
答案与解析：D 词义猜测题。由倒数第二段中的“Very few birds or insects will eat a ladybug because it gives off something that is dangerous to eat.”可知，很少有鸟或昆虫吃瓢虫。再由画线部分后的“a bird about 100 times its size”可知，当遇见比它大的鸟时，瓢虫会释放某种物质从而对鸟造成威胁。故此处的stand up to有“回击、抵御”之意。
8．What does the author think of the ladybug?
A．It is a crop?destroyer.
B．It is a good luck sign.
C．It is a little flying helper.
D．It is a big eating machine.
答案与解析：C 推理判断题。本文旨在介绍瓢虫这种能够吃害虫的昆虫，它们对于庄稼来说是得力的帮手，故C项中的helper最符合瓢虫的这一特性。

Ⅱ.阅读理解
A
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.
【语篇解读】 本文是一篇议论文。文章主要讨论了灭绝物种复活这一新技术。

A．They will die very soon.
B．They will create other problems.

答案与解析：B 推理判断题。根据第四段中的“He believes that bringing extinct animals back to life is bad for the earth... these animals no longer have a safe place to live.”和“they could cause other animals to die”可知，Stuart Primm反对灭绝物种复活是因为他认为这些复活的动物会造成一些其他的问题。
4．How does Stuart Brand feel about de?extinction?

B
One night in April, Corey Simmons got on the New York City subway, heading from Manhattan to Brooklyn to pick up his son from his grandmother. Simmons knew he needed to open the green folder (文件夹) on his legs, because inside lay his son's math worksheets that father and son were supposed to complete together.
His son, who was in third grade, had just failed a test on fractions (分数). Simmons, 40, was never great at math. He wasn't sure he remembered much about fractions. He opened the folder and started on a problem, but wasn't sure if he was doing it correctly.
Just then, a man got on the train and sat next to him.
“He looked like a professor or something，” Simmons said. “He looked kind of smart... like he knew something about math.”
Like most New Yorkers, Simmons did not often talk to other people on the subway. This time, he shared his problem with the stranger. To his surprise, the man offered to help.
The two men worked through the math problems. The stranger helped Simmons understand how to do the math, so he could later teach his son.
The moment was captured (捕获) by Denise Wilson, who was heading home from her job and saw the pair doing homework. She posted the photo on Facebook. “I really love seeing things like this especially in New York，” she wrote. “To be a dad... and put his pride aside and learn from a complete stranger... it was so cool.”
Simmons said he wasn't afraid to ask for help so he could help his son. “You have to ask questions to get information. I'm not shy to ask，” he said. “I was letting him know ‘I need help, you know, your assistance would be great here on the train.’”
The 20?minute subway lesson gave Simmons high hopes that his son would pass the next test. “He's going to knock it out of the park，” Simmons said.

Ⅱ.阅读理解
A
The great success of Finding Dory is being met with mixed feelings by experts. That's because though the movie can draw attention to our weak coral reefs (珊瑚礁) that need protection, it may lead to further damage to life at sea.
After the movie Finding Nemo came out in 2003, the clownfish (小丑鱼) became popular with every kid in America. As a result, the number of clownfish in the wild greatly dropped. Blue tangs (蓝吊鱼) also became popular pets because of the movie. Sadly, most blue tangs are caught with the help of cyanide (氰化物)．
Cyanide works on the fish, allowing them to be easily caught and sold to pet stores. Cyanide is harmful to humans. It also harms coral and other life at sea. Even the fish that are caught by using cyanide are harmed. Many end up dying within months of being brought to the store.
It is not allowed to sell fish that have been caught using cyanide in the US. However, a 2008 study discovered that up to 90% of the 11 million pet fish brought into the country each year have been caught using this harmful fishing method. More recently, two researchers Craig Downs and Rene Umberger did a study to test if the fish sold in US pet stores had been harmed by cyanide. They found that of the 100 fish bought from stores in California, Hawaii, Maryland, North Carolina, and Virginia, over half, including the blue tangs, had cyanide in their body.
To help people make better decisions when looking for fish for their kids, the researchers made a free mobile app, called Tank Watch－the app helps people to know whether a fish has been caught using illegal fishing methods.
The World Wildlife Foundation is asking fans of the movie not to “Find” Dory, but to “Protect” the beautiful fish! This means not rushing out and buying a blue tang after watching the film. As Ellen Degeneres, voice actress for Dory, says, the movie is not about “Finding” Dory, but about “putting it back to the ocean”．
【语篇解读】 很多人喜欢把海里的鱼当宠物养，这使得一些人用化学药物来捕鱼，给海洋生态系统造成了威胁。
1．What makes experts worried after the movie Finding Dory came out?
A．That people may not like it.
B．That the clownfish will disappear.
C．That people may rush out to buy a“Dory”．
D．That coral reefs may not draw any attention.
答案与解析：C 推理判断题。根据文章内容可推断，Finding Dory这部电影使得Dory这种鱼很受欢迎，专家们担心人们会大量购买这种鱼，从而对海洋生态系统构成危害。
2．What do the two studies mentioned in Paragraph 4 tell us?
A．It's very hard to catch pet fish at sea.
B．Blue tangs are very popular in the US.
C．Cyanide is not allowed to use in the US.
D．Many pet fish in the US are caught by using cyanide.
答案与解析：D 细节理解题。根据第四段的“...up to 90% of the 11 million pet fish... have been caught using this harmful fishing method.”以及“of the 100 fish bought from stores... over half... had cyanide in their body.”可知，这两个研究表明美国的很多宠物鱼都是用氰化物捕捉到的。
3．Tank Watch would most probably be used by people who want to ________.
A．buy a pet fish online
B．catch fish more easily
C．talk about movies with others
D．avoid buying illegally?caught fish
答案与解析：D 推理判断题。根据第五段的“To help... the researchers made a．.. app called Tank Watch－the app helps people to know whether a fish has been caught using illegal fishing methods.”可知，那些想要避免买到使用非法途径捕捉到宠物鱼的人会使用这个软件。
4．What Ellen Degeneres says mainly shows that people should ________.
A．avoid keeping a blue tang
B．go to watch Finding Dory
C．help experts find blue tangs
D．return their pet fish to the sea
答案与解析：A 细节理解题。根据末段的“... says, the movie is not about ‘Finding’ Dory, but about ‘putting it back to the ocean’．”可知，这个人说的话表明我们应该让蓝吊鱼回归海洋，所以不应该养蓝吊鱼。
B
Moose (驼鹿), which weigh up to 700 kilograms, can be dangerous to people. They can cause deadly traffic accidents and also can harm people and other animals by stepping on them. Wildlife biologists in the US are trying to get a correct count of this kind of big animals.
The counting is being done in Alaska's largest city, Anchorage. Recently, many moose have been found in this city. The_officials_tried_to_get_their_count,_but_the_problem_is_that_the_animals_continually_move_and_the_city_covers_an_area_of_over_5,000_square_kilometers.
In the past, officials used low?flying airplanes to watch for moose on the ground to get their count. But rules from the city's airport now prevent such flights, so Alaska's Department of Fish and Game is experimenting with a new method for counting the city's moose. The researchers are trying to collect genetic material called DNA from moose. They say this will allow them to get a more accurate (精确的) result without having to catch them.
Biologists sought help from the public during their three?day project last month. They asked people to call or send text messages to report when they saw a moose. Teams of moose hunters then quickly drove to the areas. The teams shot the moose with special darts (飞镖) designed to get small pieces of skin and hair. The darts were weighted so that they could fall off the moose and then the material could be collected. The skin and fur were then taken to a laboratory to be studied. Researchers say the darts do not hurt the animals.
Biologist Dave Battle led the project. “There's really been no technique up until now. And it's something we've been beating our brains out to work on for the last couple of years，” he said. Battle says the technology is allowing officials to improve their knowledge and management of the moose population in the Anchorage area. But he adds that it will take some time to study the DNA material to come up with specific numbers.
【语篇解读】 本文是一篇说明文。在美国的Alaska，生活着大量的驼鹿，如何计算驼鹿的数量一直是个难题。现在，人们尝试用DNA掌握驼鹿的数量。
5．What can be inferred from the underlined part in Paragraph 2?
A．The city is known for its special moose.
B．The process of counting the moose is not easy.
C．The number of the moose in the city is increasing.
D．The officials regard the moose as a serious city problem.
答案与解析：B 推理判断题。画线句句意为：官员们想要知道驼鹿的数量，但是问题是这些动物一直在移动，而且这个城市总共有五万多平方公里。因此可推测，数驼鹿这个过程不容易。
6．Why do researchers collect DNA from the moose?
A．To study their movements.
B．To get the number of the moose.
C．To drive away the moose in the city.
D．To work out ways of making them live longer.
答案与解析：B 细节理解题。根据第三段的“so Alaska's Department of Fish and Game... They say this will allow them to get a more accurate result without having to catch them”可知，研究者采集驼鹿的DNA主要是想得到他们的数量。
7．What is mainly talked about in Paragraph 4?
A．The reasons for studying the moose.
B．The purposes of counting the moose.
C．The way of collecting genetic material from the moose.
D．The value of studying genetic material from the moose.
答案与解析：C 主旨大意题。根据文章第四段可知，人们用飞镖射击驼鹿，采集皮和毛送去实验室研究，所以可知，本段主要讲述了采集驼鹿基因物质的具体方法。
8．What can we know about the project led by Battle?
A．It didn't do any harm to the moose.
B．It cost lots of money and time.
C．It was based on a previous technique.
D．It was strongly supported by the public.
答案与解析：A 细节理解题。根据第三段的最后一句和第四段的“Researchers say the darts do not hurt the animals.”可知，这个项目不会对驼鹿有任何伤害。
