While students in Hainan are quite used to clear skies, Beijing teenagers are not so lucky. As another warm winter approaches, the city can expect the normal clouds of smoke caused by air pollution.
But things could start to get better soon. The government is co-operating with a US-based environmental protection agency to update existing buses and trucks with clean fuel technology. The new technology could reduce air pollutants in existing diesel vehicles (柴油机) by 40 per cent. The programme will begin by testing buses in Beijing to see if the technology can be applied to them.
“We encourage the development of public transportation. But at the same time we need to reduce pollution from them,” said an official.
Efforts are being made to improve the capital’s environment with tighter controls on emissions (排放). Some heavily polluting factories and construction sites, such as those owned by the steel giant Shougang Group, have been asked to cut production in November and December or be closed.
Beijing was the third polluted city in the world at the end of last century, according to the UN. But thanks to recent measures, the capital has made some progress. Last year 224 clear days were rated as having good air quality. In 1998 the air quality index (指数) gave just 100 days as good.
“I am glad to see an improvement,” said a Senior 1 boy living in the northwest of Beijing. “Compared to other places, the air quality of Beijing is still worrying though. I hate the pollution. Once I was riding my bike in the morning when I almost had a traffic accident because I couldn’t see a car only metres away from me in frog.”
In early October, the skies were covered by such a thick fog that a display show by the visiting French air force was called off.
Rapid development, industry, traffic fumes (烟) and sandstorms from the desert all contribute to the city’s bad air.The passage is mainly about ________?
| A．a programme to improve Beijing’s air quality |

A mouse looked through a crack in the wall to see the farmer and his wife opening a package: What food might it contain? He was astonished to discover that it was a mouse trap!
Retreating to the farmyard, the mouse declared the warning, “There is a mouse trap in the house, there is a mouse trap in the house.”
The chicken clucked and scratched, raised her head and said, “Mr Mouse, I can tell you this is a grave concern to you, but it is of no consequence to me, I cannot be bothered by it.”
The mouse turned to the pig and told him, “There is a mouse trap in the house.” “I am so sorry, Mr Mouse,” sympathized the pig, “but there is nothing I can do about it but pray; be assured that you are in my prayers.”
The mouse turned to the cow, who replied, “A mouse trap, am I in grave danger, huh?”
So the mouse returned to the house, head down and depressed to face the farmer’s mouse trap alone.
That very night a sound was heard throughout the house, like the sound of a mouse trap catching its prey. The farmer’s wife rushed to see what was caught. In the darkness, she did not see that it was an evil snake whose tail the trap had caught. The snake bit the farmer’s wife. The farmer rushed her to the hospital. She returned home with a fever. Now everyone knew to treat a fever with fresh chicken soup, so the farmer took his hatchet to the farmyard for the soup’s main ingredient. His wife’s sickness continued so that friends and neighbors came to sit with her around the clock. To feed them, the farmer butchered the pig. The farmer’s wife did not get well, in fact, she died, and so many people came for her funeral. The farmer had the cow slaughtered to provide meat for all of them to eat.
So the next time you hear that someone is facing a problem and think that it does not concern you, remember that when the least of us is threatened, we are all at risk.We may infer that the passage is most probably a ______.

Five years ago, David Smith wore an expensive suit to work every day. “I was a clothes addict(迷),” he jokes. “I used to carry a fresh suit to work with me so I could change if my clothes got wrinkled(皱的).” Today David wears casual clothes — khaki pants and a sports shirt — to the office. He hardly ever wears a necktie. “I’m working harder than ever,” David says, “and I need to feel comfortable.”
More and more companies are allowing their office workers to wear casual clothes to work. In the United States, the changes from formal to casual office wear have been slow. In the early 1990s, many companies allowed their workers to wear casual clothes on Friday(but only on Friday). This became known as “dress-down Friday” or “casual Friday”. “What started out as an extra one-day-a-week benefit for workers has really become an everyday thing,” said business adviser Maisly Jones.
Why have so many companies started allowing their workers to wear casual clothes? One reason is that it's easier for a company to attract new workers if it has a casual dress code. “A lot of young people don't want to dress up for work,” says the owner of a software company, “so it's hard to hire people if you have a conservative dress code.” Another reason is that people seem happier and more productive when they are wearing comfortable clothes. In a study made by Levi Strauss and Company, 85 percent of employers said that casual dress has a side effect on work. Supporters of casual office wear also say that a casual dress code helps them save money. “Suits are expensive, if you have to wear one every day,”one person said. “For the same amount of money, you can buy a lot more casual clothes.”David Smith refers to himself as having been “a clothes addict” because ______________.
| A．he often wore khaki pants and a sports shirt |
| B．he couldn't stand a clean appearance |
| C．he wanted his clothes to look tidy and clean all the time |
| D．he didn’t want to spend much money on clothes |
David Smith wears casual clothes now, because ______________.
| A．they make him feel at ease when working |
| B．he cannot afford to buy expensive clothes |
| C．he looks handsome in casual clothes |
| D．he no longer works for any company |
According to this passage, which of the following is TRUE?
| A．Company workers started to dress down about twenty years ago. |
| B．Dress-down has become an everyday phenomenon since the early 1990s. |
| C．“Dress-down Friday” was first given as a favor from employers. |
| D．Many workers want to wear casual clothes to impress people. |
In this passage, the following advantages of casual office wear are mentioned EXCEPT ______________.
| A．saving worker’s money | B．making workers more attractive |

On October 12, 1987, some Chinese scientists were working at the computers to look for information they needed. Suddenly they saw a lot of very bright spots(点 )crossing the computers’ screens. At the same time the computers were working much slower. To find out what was happening they stopped their work to check some parts of the computers. To their horror(恐惧), they found out that most of their stored information was got rid of( 除掉) by computer viruses! Obviously all these computers had been infected（感染 ） by computer viruses.
It is said that the computer viruses were made by a group of young man fond of playing tricks. They all had excellent education. They created the viruses just to show their intelligence.（才智）These kinds of computer viruses are named Jerusalem( 耶路撒冷 )Viruses. These viruses can stay in computers for a long time. When the time comes they will attack the computers by lowering the function(功能), damaging their normal programs or even getting rid of all the information.
We now come to know that Jerusalem Viruses often attack computers on Fridays and that they are spreading(传播) to a list of computers.

Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different sense, to find and choose their food. A few animals depend on only one of their senses. while most animals use more than one sense.
Although there are many different types of food, some animals spend their lives eating only one type. The giant panda (大熊猫) eats only one particular type of bamboo (竹子). Other animals eat only one type of food even when given the choice. A kind of white butterfly (蝴蝶) will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet (多样化饮食). The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health, Choosing the right food, therefore, has become an area of study in modern life.We can infer from the text that humans and animals - —.
| A．depend on one sense in choosing food |
