These days we hear a lot about how air pollution is changing temperatures on the earth. New evidence from a mountaintop in China now suggests that pollution can also change the amount of rain and snow that falls in some places.
Usually, more rain falls in mountainous places than in flat areas upwind from the mountains. That’s because air can hold a lot of water. When wind blows wet air up a mountainside, the air gets colder. This temperature change often forces water to fall as rain or snow.
In recent years, however, many mountainous areas in the western United States have been getting less rain than normal. Mountains that are downwind from cities have experienced the biggest drops.
Some scientists have theorized（推理）that pollution drifts （趋势）from the cities into the mountains, affecting rainfall, but proving this link has been difficult.
Searching for answers, a team led by a scientist from the Hebrew University went to s mountain in China called Mount Hua, which is 2,060 meters tall and lies about 120 kilometers east of the Chinese city Xi’an. Since 1954, scientists have been collecting details about rainfall, humidity（湿度）, and visibility（能见度）in the area.
Using this data, the scientists compared rainfall on Mount Hua to rainfall in the nearest city, Huayin, on days with different levels of visibility. When the air was clear and people could see as far as 20 km, the scientists found that 65% more rain fell on the mountain than in the city.
But when the air was smoggy, allowing only 8 km of visibility through the mist, the mountain received just 20% more rain than the city. The new data supports the theory that pollution affects rainfall.
Some scientists believe that there are other explanations for the numbers. It’s possible, for example, that natural particles（微粒）in the air, rather than particles produced by pollution, are affecting visibility.
According to the 1^st paragraph, air pollution is changing the following EXCEPT ______.

A．the temperature	B．the amount of rain
C．the habit of eating	D．the amount of snow

According to the passage, what will probably happen when the wet air in the sky gets colder?

A．It will probably rain or snow	B．It will probably be cloudy.
C．It will probably wind	D．It will probably become dry.

Why did the team led by a scientist go to Mount Hua?

A．They wanted to pay a visit to Mount Hua.

B．They wanted to collect the data for their theory.

C．They wanted to measure Mount Hua.

D．They wanted to have a good rest on Mount Hua.

You can most probably read the passage in _______.

A．a travel guide

B．a telephone book

C．a cartoon book

D．a science book

Although women lead healthier, longer lives, the cruel perception that they reach their sell-by date and become “old” sooner than men is widespread in the workplace, research shows.
A survey of more than 2,600 managers and personnel professionals showed that age discrimination is not only common in the workplace, but is full of inconsistencies(矛盾). Six in ten managers thought that they had suffered from age discrimination——usually because they were turned down for a job for being too old or too young. Yet more than a fifth admitted that they used age as a condition when they employ new workers.
Although the survey found widespread agreement that older workers were better than younger colleagues when it came to reliability, commitment, loyalty and customer service, these qualities were not necessarily considered to be worthy of advancement. More than half of respondents believed that workers between 30 and 39 were the most likely to be advanced in their company, with only 2 per cent citing (引证)50-year-olds or above.
Dianah Worman of the Chartered Institute of Personnel and Development said that there was anecdotal evidence that people were considered old at different ages in different sectors. “We heard of one man working in IT who said he was considered too old by the age of 28,”she said.“There was no evidence to suggest that older workers were less valuable to companies than younger workers, in fact the opposite was often true because older workers often brought experience.” she added.
The findings also suggested that the Government’s ideas on age in the workforce may also be out of step with reality.
68. The text is mainly about ______.
A. the government’s idea on age in workforce
B. age discrimination in the workforce
C. the people who find work
D. the discussion about who is worth promoting
69. The underlined word “sell-by date” in paragraph 1 probably refers to______.
A. the age when they retire
B. the age when they should be promoted
C. the date on which they’re sold
D. the date when they sell goods
70. The writer’s purpose in writing the text is to ______.
A. tell the government to employ older workers
B. criticize managers who treat workers unfairly
C. report the findings of a survey
D. show he objects to age discrimination

Fear and its companion pain are two of the most useful things that man and animals possess if they are used. If fire didn’t hurt when it burned, children would play with it until their hands were burned away. Similarly, if pain existed but fear didn’t, a child could burn itself again and again because fear would not warn it to keep away from the fire that had burnt it before. A really fearless soldier—and some do exist—is not a good soldier because he is soon killed; and a dead soldier is of no use to his army. Fear and pain are therefore two guards without which man and animals might soon die out.
In our first sentence we suggested that fear ought to be properly used. If, for example, you never go out of your house because of the danger of being knocked down and killed in the street by a car, you are letting fear rule you too much. The important thing is not to let fear rule you, but instead, to use fear as your servant and guide. Fear will warn you of dangers; then you have to decide what action to take.
In many cases, you can take quick and successful action to avoid the danger. For example, you see a car coming straight towards you; fear warns you, you jump out of the way, and all is well.
In some cases, however, you decide that there is nothing that you can do to avoid the danger. For example, you cannot prevent an airplane crashing into your house, and you may not want to go and live in a desert where there are no airplanes. In this case, fear has given you its warning, you have examined it and decided on your course of action, so fear of the particular danger is no longer of any use to you, and you have to try to overcome it.
60. Children would play with fire until their hands are burnt away if _________.
A. they were not well educated at school   B. they had never played with fire before
C. they had no sense of pain             D. they were fearful of pain
61. People sometimes succeed in timely avoiding danger because _________.
A. they have gained experience     B. they are warned of the danger and take quick action
C. they jump out of the way in time D. they are calm in face of danger
62. What is implied but not stated in the passage?
A. Too much fear is harmful               B. Fear is always something helpful
C .Fear is something that can be avoided
D. Fear ought to be used as our guide in our life
63.The best title for this passage should be __________.
A. No Pains, No Gains               B. Pain and Actions
C. The Value of Fear         D .The Reason Why People Fear

People with less education suffer fewer stressful days, according to a report in the current issue of the Journal of Health and Social Behavior.
However, the study also found that when less-educated people did suffer stress it was more severe and had a stronger effect on their health.
From this, researchers have concluded that the day-to-day factors that cause stress are regular. Where you are in society determines the kinds of problems that you have each day, and how well you will cope with them.
The research team interviewed a national sample of 1, 031 adults daily for eight days about their stress level and health. People without a high school diploma reported stress on 30 percent of the study days, people with a high school degree reported stress 38 percent of the time, and people with college degrees reported stress 44 percent of the time.
“Less advantaged people are less healthy on a daily basis and are more likely to have downward turns in their health.” leading researcher, Dr. Joseph Grzywacz of Wake Forest University Baptist Medical Center, said in a prepared statement. “The downward turns in health were connected with daily stressors (紧张刺激物), and the effect of daily stressors on their health is much more damaging for the less advantaged. ”
“If something happens every day, maybe it’s not seen as a stressor.” Grzywacz says. “Maybe it is just life.”
56.Stress level is closely related to           .
A. family size   B. social position      C. body weight         D. work experience
57.Which group reported the biggest number of stressful days?
A. People without any education.   B. People without high school degrees.
C. People with high school degrees.        D. People with college degrees.
58.The less advantaged people are, the greater            .
A. the effect of stress on their health is B. the effect of education on their health is
C. the level of their education is     D. the degree of their health concern is
59.Less-educated people report fewer days of stress possibly because          .
A. they don’t want to tell truth        B. they don’t want to face the truth
C. stress is too common a factor in their life D. heir stress is much greater

Waste to Energy—JUST BURN IT!
WHY BURN WASTE?
Waste-to-energy plants generate (产生) enough electricity to supply 2.4 million households in the US. But, providing electricity is not the major advantage of waste-to-energy plants. In fact, it costs more to generate electricity at a waste-to-energy plant than it does at a coal, nuclear, or hydropower plant.
The major advantage of burning waste is that it considerably reduces the amount of trash going to landfills. The average American produces more than 1,600 pounds of waste a year. If all this waste were landfilled, it would take more than two cubic yards of landfill space. That’s the volume of a box three feet long, three feet wide, and six feet high. If that waste were burned, the ashes would fit into a box three feet long, three feet wide, but only nine inches high!
Some communities in the Northeast may be running out of land for new landfills. And, since most people don’t want landfills in their backyards, it has become more difficult to obtain permits to build new landfills. Taking the country as a whole, the United States has plenty of open space, of course, but it is expensive to transport garbage a long distance to put it into a landfill.
TO BURN OR NOT TO BURN?
Some people are concerned that burning garbage may harm the environment. Like coal plants, waste-to-energy plants produce air pollution when the fuel is burned to produce steam or electricity. Burning garbage releases the chemicals and substances found in the waste. Some chemicals can be a threat to people, the environment, or both, if they are not properly controlled.
Some critics of waste-to-energy plants are afraid that burning waste will hamper (妨碍，阻碍) recycling programs. If everyone sends their trash to a waste-to-energy plant, they say, there will be little motive to recycle. Several states have considered or are considering banning waste-to-energy plants unless recycling programs are in place. Massachusetts, New Jersey, and New York City have delayed new waste-to-energy plants, hoping to increase the level of recycling first.
So, what’s the real story? Can recycling and burning waste coexist? At first glance, recycling and waste-to-energy seem to be at odds (不一致), but they can actually complement (弥补) each other. That’s because it makes good sense to recycle some materials, and better sense to burn others.
Let’s look at aluminum, for example. Aluminum mineral is so expensive to mine that recycling aluminum more than pays for itself. Burning it produces no energy. So clearly, aluminum is valuable to recycle and not useful to burn.
Paper, on the other hand, can either be burned or recycled—it all depends on the price the used paper will bring.
Plastics are another matter. Because plastics are made from petroleum and natural gas, they are excellent sources of energy for waste-to-energy plants. This is especially true since plastics are not as easy to recycle as steel, aluminum, or paper. Plastics almost always have to be hand sorted and making a product from recycled plastics may cost more than making it from new materials.
To burn or not to burn is not really the question. We should use both recycling and waste-to-energy as alternatives to landfilling.
