听力原文： About 70 million Americans are trying to lose weight. That is almost 1 out of every 3 people in the United States. Some people go on diets. This means they eat less of certain foods, especially fats and sugars. Other people exercise with special equipment, take diet pills, or even have surgery. Losing weight is hard work, and it can also cost a lot of money. But why do so many people in the United States want to lose weight？

Many people in the United States worry about not looking young and attractive. For many people, looking good also means being thin. Other people worry about their health. Many doctors say being overweight is not healthy. But are Americans really fat？

Almost 30 million Americans weigh at least 20 percent more than their ideal weight. In fact, the United States is the most overweight country in the world. "The stored fat of adult Americans weighs 2.3 trillion pounds," says University of Massachusetts anthropologist George Armelages. He says burning off that stored energy would produce enough power for 900,000 cars to go 12,000 miles.

Losing weight is hard work, but most people want to find a fast and easy way to take off fat. Bookstores sell lots of diet books. These books tell readers how to lose weight. Each year, dozens of new books like these are written. Each one promises to get rid of fat.

听力原文： In the past few years, millions of Americans have become suddenly enthusiastic about the bicycle as if it were a great new invention. Annual bicycle sales doubled between 1960 and 1970, and there are nearly 70 million bicycles in the United States today.

Of course, the bicycle has been around for more than 160 years and this isn't America's first bicycle passion. A wave of bicycle enthusiasm swept the land in the late 1800s and bicycle production was up to two million in 18917. Then with the coming of the automobile, bicycle declined, and for decades remained popular only with children and a few adults.

Now, a national concern with air pollution and physical fitness has brought the bicycle back to the forefront, particularly with adults. More than eight million bikes were sold in the United States last year, a third of which bought by adults. But the year before, only 15 percent of new bicycle sales were for adults.

(33)

A．Nearly 7 million.

B．Nearly 17 million.

C．Nearly 70 million.

D．Nearly 77 million.

The world has become a world of cities. With the present rate of urban growth（3. 8% in the

The world has become a world of cities. With the present rate of urban growth(3. 8% in the Third World) , the majority of the population of the world will be living in cities by the year 2000. This will transform the rural-urban equation which has marked the history of mankind up to now and will call for new example and a great deal of innovation to face this phenomenon. This being so, one must accept the fact that for some years to come, no policy will be capable of stopping or reversing the present migratory trend from the rural areas to the cities in the Third World. In Africa, the urban population will reach 330 million people by the end of the century as against 150 million in 1995. The number of people living in shanty-towns (贫富窟) will inevitably increase in spite of the efforts to improve housing conditions. Africa alone needs to build 12 million housing units between now and the year 2000 to meet its most basic needs. In an ILO study, M. S. V. Sethuraman estimates that in 70 Third "World cities the proportion of people living in shanty-towns varies from 15% to 70% and that about US $ 116 billion is required to give minimum comfort to these people by the turn of the century—less than US $ 10 billion per year. The world population is growing at a rate of about 90 million people per year, with the Third World accounting for 80 million of them. The pressure on cities can only go on increasing. The urban population of the developing countries will exceed 2 billion people by the year 2000 and since the main reason for the high demographic (人口统计的) growth is poverty, the additional population will be mostly made of people of very limited means. If the urban population of the developing countries exceeds 2 billion people by the year 2000, the main problem the additional people will face is______.

A.housing

B.food

C.poverty

D.limited land
