London used to be “foggy”( 有雾的) for the same reason that cities like Beijing or Chongqing are “foggy” today. The “fog” was in fact smog(烟雾), a mixture of smoke and fog.In other words, it was made by air pollution. In London, some of this pollution came from factories, but much of it came from the coal(煤)that people burnt in their houses to keep warm during the winter. By the 1950s, London’s smog problem had become so bad that the government decided to do something to clean the air. A new law was made and nobody could burn coal in any British city. In a few years, the air became much cleaner. There were no more “pea-soupers”.
Many Chinese cities now face the same sort of problem with air pollution that London faced 40 or 50 years ago. However, this problem is more difficult for Chinese cities to solve. One reason is that more of the pollution comes from the factories, rather than from coal burnt in people’s houses. If these factories were closed, this would harm the economy and lots of people would lose their jobs. Another reason is that changing from coal to cleaner fuel(燃料), like gas, is quite expensive.
However, the air in many Chinese cities is becoming cleaner and cleaner, as the government and people pay more and more attention to cutting down pollution. As a result, there are fewer “pea-soupers” in Beijing than there used to be.
小题1:What was the main reason for air pollution in London?
A.There was too much smoke in the sky.
B.There were too many factories in the city.
C.People burnt too much coal in the houses.
D.The city was too big for the cleaners to clean.
小题2:What does the underlined word “pea-soupers” refer to?
A.SmogB.Smoke
C.GasD.Coal
小题3:Which sentence is Not true?
A.Air pollution is serious in Beijing and Chongqing.
B.Using coal is much more expensive than using gas.
C.Factories made much more pollution in China.
D.The reasons of air pollution in London and Beijing are different

小题1:C
小题2:A
小题3:B

If you are one of those who want to know how to increase your vocabulary, there are some ways you may find useful. In fact, it is not that difficult to learn new words, but to remember them for a lifetime seems not to be so easy.
To make it easier, you can try word associations(联想). Try to find a connection between a new word and things or people you know. For example, if your neighbour is an unselfish person who cares about the needs of other people, think about this person every time you see the word, and very soon you'll start actively using it.
Try to use the words you learn as often as possible. Perhaps you are not sure which situations they should be used in, or whether you pronounce(发音) them correctly, but practice is the best way to understand that. It is not enough to find out the meaning of a word. You should hammer (敲打) it into your mind by using it in actual conversations in everyday life.
Also, it may be helpful to know the meaning of the word roots, prefixes (前缀) and suffixes (后缀), especially if they have a Greek or Latin origin(起源). Even if you meet a long unfamiliar word, it will be easy to know its meaning if you know the general meaning of its parts.  For example, if you see the word "philanthropy", it won't be difficult to surmise what it means if you know that "anthropo" means "human" and "philo" means "loving". Not only can ancient Greek and Latin be helpful, but a number of modern languages as well. So, if you speak French,  Italian, Spanish or Portuguese, guess the meaning of an unfamiliar English word if it sounds like  a word from another language you know.
小题1: Which of the following old sayings can show the main idea of Paragraph 3?
A.Every dog has his day.
B.Practice makes perfect.
C.Every coin has two sides.
D.Where there is a will there is a way.
小题2: According to the last paragraph, what does the writer think is important?
A.Learning to use several different modern languages.
B.Learning some very difficult words in the English language.
C.Knowing the meaning of the word roots, prefixes and suffixes.
D.paying more attention to words that have a Greek or Latin origin.
小题3:The underlined word "surmise" in the last paragraph means_______.
A.guessB.suggest
C.proveD.remember
小题4: what's the writer's purpose in writing the passage?
A.To tell us how he or she learnt English well.
B.To explain why it is not hard to learn new words.
C.To prove that learning new words can be really fun.
D.To tell us some good ways of remembering new words.

 Scientists have made the world’s first human-sheep----with the body of a sheep and half-human organs(器官). Amazing, but true. The sheep is15percent human and 85 percent sheep. The breakthrough(突破)makes it possible to use animal organs in human bodies in the future. Professor Esmail Zanjani of University of Nevada, US, has spent seven years And over $9 million on the work.

It is two months since MH730 first went missing in the early hours of March 8th, while flying from Kuala Lumpur to Beijing. Malaysia Airlines said it was terribly sorry that MH370 ended in the southern Indian Ocean. People are losing hope that the passengers on the      could return alive and realize they should know how to save themselves when accidents like this happen in the air.
  1985, an Australia professor, Ed Galea, has interviewed 2,000 survivors of 105 airplane accidents, searching for the keys to survival (n.幸存) and found out      golden rules after years of research.
First, make sure that the airline does not keep your family members too far away on the plane, if you are traveling in family group.     ? It’s natural that while feeling in danger, you’ll probably want to meet the family before you can calmly move out.
Second, how do you untie (解开) your seat belt on a plane? By lifting a latch.            you can’t untie your seat belt, you can hardly run away and your chances of survival will drop.
Third, the           to the exits (逃生口), the more likely you are to survive. Count exactly how many rows you are from the nearest two exits. Why two exits? Because this helps you find at least               even in the sudden dark during an accident.
Fourth, we would be safer if airline seats faced backward, according to Galea’s research. But the problem is that most of the passengers              traveling with their back facing the direction of travel.
Fifth, “Smoke is dangerous to your health. If you take in too much of it, your will die,” explains Galea. You must learn how to use a smoke mask. Without the knowledge of putting on a mask, you’ll              time trying to put it on—time that could be used to run away.
At last, listen to the flight attendants before flying and look      at everything shown on a video or a safety card. Always be prepared. Good luck to you.

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
