听力原文：W: Air pollution is one of the most serious problems in the world. Polluted air can make us sick or even kill us. Why isn't more done to stop it？
M: Everyone wants to stop it, but it is a difficult problem to solve. Meat pollution is mused by things people need.
W: What do you mean？
M: Well, automobiles and airplanes cause pollution but they also provide transportation.
W: Right. And factories cause air pollution but they provide people with jobs and products.
M: Cities are the worst offenders. In crowded cities, factories and cars can add tons of pollution to the air every day.
W: Yes. When I drove, to town yesterday, the clear air changed. It seemed like a dark cloud hung over the city.
M: Nobody likes air pollution. It smells bad; it makes it difficult to breathe.
W: True, it even damages the plants that provide tis with food. No wonder we get sick. It's dangerous to everyone's health.
M: I think everyone knows it is a serious problem. When air pollution can even damage strong materials like steel and concrete; think what it does to poor humans.
W: It is terrible, and yet we do need some things that cause it. We'll have to try to figure out a solution.

A．Most people don't think it is a serious problem.
B．Most of our pollution is caused by things people need.
C．The government has not spent enough money to stop it.
D．The seriousness of pollution has not been realized by the government.

How many really suffer as a result of labor market problems？ This is one of the most critical yet contentious social policy questions. In many ways, our social statistics exaggerate the degree of hardship.
Unemployment does not have the same dire consequences today as it did in the 1930's when most of the unemployed were primary breadwinners, when income and earnings were usually much closer to the margin of subsistence, and when there were no countervailing social programs for those failing in the labor market. Increasing affluence, the rise of families with more than one wage earner, the growing predominance of secondary earners among the unemployed, and improved social welfare protection have unquestionably mitigated the consequences of joblessness. Earnings and income data also overstate the dimensions of hardship. Among the millions with hourly earnings at or below the minimum wage level, the overwhelming majority are from multiple-earner, relatively affluent families. Most of those counted by the poverty statistics are elderly or handicapped or have family responsibilities which keep them out of the labor force, so the poverty statistics are by no means an accurate indicator of labor market pathologies.
Yet there are also many ways our social statistics underestimate the degree of labor-market- related hardship. The unemployment counts exclude the millions of fully employed workers whose wages are so low that their families remain in poverty. Low wages and repeated or prolonged unemployment frequently interact to undermine the capacity for self-support. Since the number experiencing joblessness at some time during the year is several times the number unemployed in any month, those who suffer as a result of forced idleness can equal or exceed average annual unemployment, even though only a minority of the jobless in any month really suffer. For every person counted in the monthly unemployment tallies, there is another working part-time because of the inability to find full-time work, or else outside the labor force but wanting a job. Finally, income transfers in our country have always focused on the elderly, disabled, and dependent, neglecting the needs of the working poor, so that the dramatic expansion of cash and in-kind transfers does not necessarily mean that those failing in the labor market are adequately protected.
As a result of such contradictory evidence, it is uncertain whether those suffering seriously as a result of thousands or the tens of millions, and, hence, whether high levels of joblessness can be tolerated or must be countered by job creation and economic stimulus. There is only one area of agreement in this debate--that the existing poverty, employment, and earnings statistics are inadequate for one of their primary applications, measuring the consequences of labor market problems.
Which of the following is the principal topic of the passage？ ______
A．What causes labor market pathologies that result in suffering.
B．Why income measures are imprecise in measuring degrees of poverty.
C．Which of the currently used statistical procedures are the best for estimating the incidence of hardship that is due to unemployment.
D．How social statistics give an unclear picture of the degree of hardship caused by tow wages and insufficient employment opportunities.

听力原文： The climate of the west coast is the most moderate in Canada. Summers are coast and fairly dry and winters are mild, cloudy and wet. Even in mid-winter, average temperatures are usually above freezing.
The central plain from the Rocky Mountains to Great Lakes is characterized by cold winters, short but hat summers, and light snow and rain.The large water-surfaces of Central and Eastern Canada produce considerable modification in the climate. Southern Ontario and Quebec experience cold, damp winters and hot, humid summers.
Most of Atlantic Canada has a humid climate owing to its marine character. Nevertheless, it experiences weather systems arriving from the dry continental interior as well as from the sea. The combined influence of these systems creates some of the most variable day-to-day weather conditions to be encountered anywhere in Canada.
The north-central part of Canada is usually snow-covered for more than half of the year, with a frost flee period of barely two months. Rain is relatively light. Further north, on the islands along the Arctic coast and round Hudson Bay, the land is always frozen. Average temperatures stay above freezing for only a few weeks of the year. The Arctic Islands and the northern border of the mainland do not have a summer season of the kind known in Southern Canada.

听力原文：Why are college students so prone to sleep deprivation？ The problem often begins during the teen years. Most high school kids admit that they are often sleepy and 15 percent admit that they fall asleep in class.
Lack of sleep causes many problems, not the least of which is the difficulty it adds to learning. It's also detrimental to the immune system and motor skills. Students (and everyone else) need at least eight hours of sleep to maintain optimum health and learning capabilities. Yet, with the pressure of school, family and social life, few students are sleeping near the required amount.
College life only escalates the problem. Added to the above activities are more hours needed for studies. Some students also hold down a part time job to help defray college expenses. Some students are married and trying to support a family. Because of all these pressures there is also an increase in stress. Stress can lead to insomnia and even more lost sleep.
With the approach of finals, the problem can only grow worse. Students force themselves to stay awake to study. It's called cramming for exams, and it can eat away at sleep hours already far too meager. Too many nights of forced wakefulness can eventually lead to a case of full-blown insomnia and other sleep abnormalities.

A．Eating disorders, low immunity and poor motor skills.
B．Difficulty concentrating, poor motor skills, divorce.
C．Low immunity, poor self esteem, eating disorders.
D．Poor motor skills, difficulty concentrating, low immunity.

听力原文：A: About big international issues: what do you see as the most important environmental issues of the moment？
B: It’s quite difficult to make a kind of hierarchy of worry here, because so many issues are there, and so … and they’re all very very important. But I think it has to be said that as far as we we’re concerned, as a campaigning organization, it really is the rain forest that we are concentrating on most. If we don’t take action on that issue within the next five years, then environmental pressure groups won’t have anything to do in ten years’ time, because there won’t be any rain forests, really, for them to campaign about. So this is a critical period for the rain forests, the next five years, and there is enough flexibility in the system to allow us to hope that we’re going to be able to make some changes during that time. So that’s why we’ve made it our priority.
A: What’s so important about the rain forests, then？ Er, what’s, what’s the difference between having them or not having them？ Isn’t it just, you know, basically either there’re a lot of trees there or there aren’t a lot of trees there？
B: Uhh…well that’s what some people would like to think. Um, there, it’s important in many different ways, important firstly for the countries themselves, in terms of the fact that millions of people depend on the rain forests for their livelihood, and for their … the quality of their environment, through the protection of watersheds, and so on. Secondly, they’re important because of the biological richness of the rain forests. Um, a genetic chest … treasure chest is how they’ve been described. Um, more than 60% of the world’s species is to be found in the rain forests. Write that off, and you write off that genetic storehouse. Lastly, they’re important at international level because of the impact on climate patterns that one would find if the rain forests were destroyed. So, whether you’re looking closely at the tribal people who depend on them, the countries which depend on them, the international community which depends on them, indeed the, the, you know, the creatures themselves, um, it’s actually the most critical issue that we face. And our prime job is of course to try and get people to understand how it is, even in countries where there are no rain forests, that they still have a connection with that rain forest.

听力原文： The World Bank says air pollution is one of the worst environmental problems in large cities around the world. Air pollution causes breathing problems. It also threatens crop production in farm areas near huge cities.
The United Nations Environment Program says that air pollution reduces the amount of crops produced, h also reduces the nutrient level of crops. As a result, both the buyer and the seller of crops are hurt by air pollution.
The UN says dirty air is a major source of metal in crops. These metals include lead, zinc and copper. These metals can build up to dangerously high levels in the parts of plants that people eat. The German Appropriate Technology Exchange, GATE, reports that eating these metals can cause developmental problems and low intelligence levels among children. Some kinds of cancers and kidney damage have also been linked to metals in crops.
Who is hurt by air pollution？
A．The buyer.
B．The seller.
C．Both the buyer and the seller.
D．None.
