    Roosegaarde, an artist and designer from Dutch has thought of a device(装置). He hopes it will make Beijing's sky clear again and help the people with masks breathe fresh air again in Beijing.
    An electromagnetic field(电磁场) will pull the dirty particles in the air to the ground, and then they can be easily cleaned.
    Roosegaarde says, "It's like when you have a balloon which has static electricity(静电) and your hair goes toward it. Smog happens the same way as the hair."
    His workplace has reached an agreement with the Beijing government to test the technology in one of the capital's parks.  Beijing's skies are regularly covered by grey smog. Serious cases of air pollution are often reported in Beijing. Roosegaarde says an indoor test has already shown it works well and he is confident of the results. With the help of a team of scientists and engineers, he is sure that the device can be worked outside.
    "Beijing is a very good place to test the device because the smog in Beijing is quite low and there's not so much wind." says Roosegaarde. "We'll be able to make the air pure but the most difficult thing is to remove the smog. As a result, you can see the sun again."
    Roosegaarde also reminds us that his aim is not only to give a plan to solve Beijing's dirty air pollution but also to make people pay attention to the environment problem. He adds, "This is not the real answer for smog. The real answer to do with it is clean cars, different industry and different lifestyles. " However, he hopes the project will make the citizens realize the differences between clean air and smog-filled air.
    小题1:The device works by_______.
    A．helping keep the particles out with more masks
    B．pulling particles to the ground with an electromagnetic field
    C．absorbing hair with a balloon with static
    D．creating clean air and letting it out into the sky
    小题2:What does Roosegaarde use his device for?
    A．To make smog.B．To make the air clean
    C．To make static electricity.D．To make Beijing's parks beautiful.
    小题3:After reading the passage, we can know_______.
    A．the device doesn't work well indoors
    B．the people with masks can breathe fresher air
    C．Beijing government agreed to test the device
    D．clean cars aren't helpful to the environment in Beijing
    小题4:Roosegaarde hopes people in Beijing can_______.
    A．pay attention to air pollution and solve the problem finally
    B．invent more devices to clean the smog in Beijing
    C．drive modern cars and try different lifestyles
    D．realize how serious the pollution they're facing is

    小题1:B
    小题2:B
    小题3:C
    小题4:A

    Yang Nan, 17, was happy to move to her new home in a northern area of Beijing. She was told that her neighborhood used to be rich farmland planted with vegetables, corn and wheat. But looking at the new road, beautiful parks and supermarkets, to her surprise, Yang couldn't see any sign that food was once grown there.
    Yang is not alone. In recent years, many Chinese people have moved into new houses in country areas. Tall buildings have been built everywhere in the suburbs. The crops and fruit trees are no more grown there. But these changes have caused big problems too, warns Gan Zangchun, an official（官员）at the Ministry of Land and Resources(国土资源部）．
    "Chinese cities are growing very fast. This has made the area for farmland much smaller than before. This is really bad for the country's ability to grow food, not to mention the lives of farmers," said Gan last Monday.
    As the population of China is growing all the time, the country needs more farmland to grow food for the increasing people of China. But the recent rise in house prices has made selling land a good business. A lot of land has been used to build new houses for sale. So you can see, the shortage of the farmland is now a very serious problem.
    Pollution, such as, oil pollution, industrial(工业) pollution and water pollution, which makes land useless, is another reason for the big drop in China's farmland. About 2.67 million square kilometers of land in China have been polluted and turned into desert.
    Today, can we use less farmland to grow enough food for more people? Of course not! The government wants China to have at least 120 million hectares（公顷） of farmland. Only in this way can we raise such a big population. But there are only about 121.8 million hectares left. "It will be really difficult to reach the goal", Gan said. He said that the government would fight illegal(非法的) land use and something useful must be done to stop farmland from becoming desert.
    小题1:The article seems to tell us that_____________.
    A．farmland is in danger
    B．countryside is turned into towns
    C．farmland has been sold
    D．Chinese cities are growing fast
    小题2:From what Gan Zangchun said, we know he is worrying about ____________.
    A．China's development is too slow
    B．the population of China is growing fast
    C．Chinese people have worse life than before
    D．the reduction(减少) and pollution of the farmland
    小题3:What size of the land have been polluted and turned into desert?
    A．120 million hectares.
    B．121.8 million hectares.
    C．2.67 million square kilometers.
    D．Millions of square kilometers.
    小题4:Which statement of the following is NOT true?
    A．Yang Nan's new home is in a northern area of Beijing.
    B．The country needs enough farmland so that the farmers can grow enough food for the people of China.
    C．Chinese cities are growing too slowly so the government encourages people to change the farmland into towns.
    D．Pollution is also an important reason for the big drop in China's farmland.
    小题5:What will the government do with the problem of the drop in China's farmland?
    A．Government needs farmland to grow food for the people of China.
    B．Government will order not to build new towns any more.
    C．Government will stop the growth of the cities in order to stop selling farmland for business.
    D．Government will fight illegal land use and stop farmland from becoming dessert.

    People have known since ancient times that aspirin（阿司匹林） reduces pain and lowers high body temperature. But that is not all the drug can do. In recent years, it has been used in other ways, too. Small amounts may help prevent a stroke or heart attack. One recent study showed that some people who took two aspirin pills a day had lower rates of colorectal cancer. And, some researchers say aspirin may help patients with colon cancer live longer. So, how did aspirin become so important? The story begins with a willow（柳树）．
    2, 000 years ago, the Greek doctor Hippocrates advised his patients to chew on the bark and leaves of the willow. The tree contains a chemical called salicin. In the 1800s, researchers discovered how to make salicylic acid from the chemical. In 1897, a chemist named Felix Hoffmann at Friedrich Bayer and Company in Germany created acetyl salicylic acid. Later, it became the active substance in a medicine that Bayer called aspirin. The "a" came from acetyl. The "spir" came from the spirea plant, which also produces salicin. And the "in" ? That is a common way to end medicine names.
    In 1982, a British scientist shared the Nobel Prize in Medicine in part for discovering how aspirin works. Sir John Vane found that aspirin prevents the body from making the natural substances called prostaglandins. Prostaglandins have several effects on the body. Some cause pain and swelling（肿）． Prostaglandins also make the heart, kidneys(肾) and blood vessels work well. So there is a problem. Aspirin works against all prostaglandins, good and bad. It can also harm the inside of the stomach, and sometimes it can cause bleeding.
    But a British study released in 2009 suggested that taking another drug with a small amount of aspirin may help reduce the risk of bleeding. If this proves true, it would help thousands of people who are seeking to prevent life-threatening conditions.
    小题1: The writer wrote this passage to______.
    A．tell us the harm of aspirin
    B．help us know aspirin better
    C．explain why aspirin is useful
    D．prove that aspirin is a good medicine
    小题2:What do we learn about aspirin from Paragraph 1?
    A．It is not used until recent years.
    B．Using it for a long time may lead to cancer.
    C．It is very dangerous if it is used in the wrong way,
    D．It has gained important new uses in recent years.
    小题3:When was the acetyl salicylic acid created?
    A．about 2,000 years ago.B．In the early 1800s.
    C．In the late 1800sD．In recent years
    小题4:What is waiting to be solved according to the last paragraph?
    A．The bleeding caused by taking aspirin.
    B．How to reduce the risk of getting colorectal cancer.
    C．How to help patients with colon cancer live longer
    D．The problem of low body temperature caused by taking aspirin

    Everybody hates rats. But rats may soon be man’s new good friend.
    What happens after an earthquake? We send in rescue(援救)dogs. Why? Because they can smell people. Dogs save lives. They help rescuers to find living people. But dogs are big and they can’t get into small spaces. So now a new research project is using a smaller animal to save lives: the rat.
    How does it work? First, the rat is trained to smell people. When this happens, the rat’s brain gives a signal(信号). This is sent to a small radio on its back, and then the rescuers follow the radio signals. When the rat’s brain activity jumps, the rescuers know that someone is alive. The rat has smelled that person.
    Although there are already robots which can do this job, rats are better. “Robots’ noses don’t work well when there are other smells around. Rats are good at that.” Rats can also see in the dark, they are cheaper and quicker to train than dogs, and unlike robots, they don’t need electricity!
    The “rat project” is not finished, but a scientist says, “It would be great. A rat could get into spaces we couldn’t get to, and a rat would get out if it wasn’t safe.” Perhaps for the first time in history, people will be happy to see a rat in a building (but only after an earthquake, of course).
    小题1:In the writer’s opinion, rats may become man’s new friend because         .
    A．they can be food for people
    B．they can help rescuers to find living people
    C．they are lovely
    D．they can completely replace man’s rescue jobs
    小题2:What does the underlined word “this” mean?
    A．An earthquake.
    B．The rat has smelled a person
    C．The rat has smelled that someone is alive
    D．The rat has found a robot.
    小题3:Which of the following is NOT true?
    A．Rats don’t need electricity.
    B．Rats are better than robots when smelling.
    C．Rats are as clever as radios.
    D．Rats can see things in the dark when doing rescues.
    小题4:Why does the “rat project” sound great according to the passage?
    A．Because rats can get into very small spaces.
    B．Because rats have better noses than dogs.
    C．Because rats don’t like robots.
    D．Because rats are brave.
    小题5:Which is the best title of this passage?
    A．Ways of saving peopleB．Rats and robotsC．After earthquakeD．Rats for rescue

    We’ve all heard of mermaids. They are the beautiful half-human, half-fish creatures(生物). They have the head and body of a human and the tail of a fish. We also know that mermaids only exist in fairy tales. But where did all the stories about these creatures come from? If you have ever seen a manatee, then you might have an idea.

    Manatees, which are also called sea cows, are mammals(哺乳动物) that live in the sea. Since they are mammals, they have to swim up to the surface to breathe air. Many people believe that the story of the mermaid began with the ancient sailors who saw the manatees putting their heads out of the water to breathe. Because manatees are upright when they do this, it looks like they are standing. If a sailor saw a manatee doing this from far away across the sea, it is possible that the sailor would mistake the manatee for a creature that is half-human, half-fish.
    Mermaids are described as having very long hair. This is probably because manatees like to swim up to the surface of the water in areas where there is sea grass. Manatees eat all kinds of plants in the sea, including sea grass. The sea grass around the manatee’s head when they eat could create a picture of long hair.

    Manatees also have powerful tails that are very similar to the fish-like tail of a mermaid. The sailors probably watched manatees come up for air and then swim back below the surface, using their paddle-shaped tails. This would explain why the sailors thought mermaids had fish-like tails.
    小题1:What are mermaids?
    小题2:Where do manatees live?
    小题3:Do manatees need to breathe air out of water?
    小题4:What do manatees eat?
    小题5:Why did the ancient sailors mistake manatees for mermaids?

    The largest animal ever to live on Earth is the blue whale（鲸鱼）. It weighs(重) about 80 tons-more than 24 big elephants. It is more than 30 metres long. A new baby whale weighs as much as a big elephant. Cats won't die if they fall off very high places because they can turn themselves up the right way so as to keep their bodies safe. One cat fell off 32 floors onto the street, but it was just hurt a little. A bear can run as fast as a horse.  A new-born panda is smaller than a mouse and weighs about 100 grams.  Elephants are the most careful animals in their love. A male（雄性） elephant may show his lady love for up to three years until the female(雌性) elephant takes his love. They often show their love by touching each other's body. Usually, wolves do not hurt people. For years a Canadian newspaper says that they would give anyone a lot of money if he or she could show that a wolf could hurt a person. But nobody could do that. Wolves do not usually go together though（尽管） they may do this in winter and they only hurt people at an unusual time.
    小题1:How much does a new-born blue whale weigh?
    A．About 10 tonsB．As much as a baby elephant
    C．About 80 tonsD．About 3 tons

    Have you ever stayed in a hotel? Most Chinese hotels often provide guests with things like disposable (一次性的) toothbrushes, toothpaste, shampoo and slippers. Many guests like the idea because they don't have to bring their own. But, if you travel to Beijing, remember to bring your own things. Starting from June, some hotels in Beijing will no longer provide guests with these disposables. They want to ask people to use less disposable things.
    Many disposable things are made of plastic. People throw them away after only using them once. It is a waste of natural resources and is very bad for the environment. Do you know, one Chinese person makes as much as 400kg of waste a year! Most of that waste comes from disposable things. In Beijing, people throw away about 19,000 tons of plastic bags and 1,320 tons of plastic lunch bowls every year! Plastic can take between 100 and 400 years to break down. So the less plastic we throw out, the better the environment will be. So, wherever you travel, bring your own things and use them again and again.
    Back at home and school, you can also do something to make our world a better place. Try to do these things in your daily life: Use cloth shopping bags, not plastic ones. After using a plastic bag, wash it out and let it dry. Then you can use it over and over again. Do not use paper cups. At your school canteen（食堂）, use your own bowl and chopsticks instead of disposable ones.
    小题1:Why do many hotels provide guests with some disposable things?
    A．Let their guests be convenient during their travelling.
    B．Hope their guests use less disposable things.
    C．Wish their guests to save money.
    D．Want their guests to use more disposable things.
    小题2:Some Beijing hotels will no longer provide guests with _______.
    A．cheap food and drinkB．disposable things
    C．good serviceD．free TV programmes
    小题3:Which of the following is NOT true?
    A．Many disposable things are made of plastic.
    B．Throwing disposable things away is a waste of natural resources.
    C．Plastic is very bad for the environment.
    D．Plastic breaks down easily.
    小题4:What can we do to make our world a better place at home and school?
    A．Use shopping bags made of plastic.
    B．Do not throw away paper cups.
    C．Use disposable plates, bowls and chopsticks.
    D．Do not forget to reuse daily necessities（日用品）.
    小题5:We can tell from the story that _________.
    A．people don't like disposable things at all
    B．we can't use paper or plastic bowls at school
    C．we should use less plastic things and protect our environment
    D．hotels won't provide disposable things because they want to save money
