题目内容

The advantages and disadvantages of a large population have long been a subject of

discussion among economists. It has been argued that the supply of good land is limited. To feed a large population, poor land must be cultivated and good land made full use of. Thus, each person produces less and this means a lower average income than could be obtained with a smaller population. Other economists have argued that a large population gives more opportunities for specialization such as ports, roads, and railways, which are not likely to be built unless there is a big demand to justify them.

One of the difficulties in carrying out a world-wide birth control program lies in the fact that official attitudes to population growth vary from country to country depending on the level of industrial development and the availability of food and raw materials. In a developing country where a vast expanding population is pressing hard upon the limits of food, space and natural resources, it will be the first concern of the government to place a limit on the birthrate, whatever the consequences may be. In a highly industrialized society the problem may be more complex. A decreasing birthrate may lead to unemployment because it results in a declining market for products. When the pressure of the population on housing declines, prices also decline and the building industry is weakened. Faced with considerations such as these, the government of a developed country may well prefer to see a slowly increasing population, rather than one which is stable or in decline.

54．According to the first paragraph, a smaller population may mean______ if land is limited.

A．lower productivity, and a lower average income

B．lower productivity, but a higher average income

C．higher productivity, and a higher average income

D．higher productivity, but a lower average income

55．In a developed country, people will perhaps go out of work if the birthrate_______.

A．goes up B．goes down C．remains stable D．is limited

56．It is not easy to carry out a worldwide birth-control program because______.

A．there are too many underdeveloped countries in the world

B．developing countries are short of food and raw materials

C．even developed countries may have some complex problems of population

D．different governments show quite opposite views to the population

This year some twenty-three hundred teenagers（young people aged from 13 —19）from all over the world will spend about ten months in U. S. homes. They will attend U.S. schools, meet U.S. teenagers, and form impressions of the real America. At the same time, about thirteen hundred American teenagers will go to other countries to learn new languages and gain a new understanding of the rest of the world.

Here is a two-way student exchange in action. Fred, nineteen, spent last year in Germany with George’s family. In turn, George’s son Mike spent a year in Fred’s home in America.

Fred, a lively young man, knew little German when he arrived, but after two months’ study, the language began to come to him. The school was completely different from what he had expected — much harder. Students rose respectfully^① when the teacher entered the room. They took fourteen subjects instead of the six that are usual in the United States. There were almost no outside activities.

Family life, too, was different. The father’s word was law, and all activities were around the family rather than the individual. Fred found the food too simple at first. Also, he missed having a car.

“Back home, you pick up some friends in a car and go out and have a good time. In Germany, you walk, but you soon learn to like it.”

At the same time, in America, Mike, a friendly German boy, was also forming his idea. “I suppose I should criticize^② American schools,” he says. “It is far too easy by our level. But I have to say that I like it very much. In Germany we do nothing but study. Here we take part in many outside activities. I think that maybe your schools are better in training for citizens. There ought to be some middle ground between the two.”

Notes:

respectfully adv. 尊敬地，谦恭地

criticize vt. 批评，责备

Choose the best answers according to the above:

This year __ teenagers will take part in the exchange programme between America and other countries.

A. twenty-three hundred B. thirteen hundred

C. over three thousand D. less than two thousand

What is particular in America schools is that __.

A. there is some middle ground between the two teaching buildings.

B. there are a lot of outside activities

C. students usually take fourteen subjects in all

D. students go outside to enjoy themselves in a car

After experiencing the American school life, Mike thought __.

A. a better education should include something good from both American and Germany

B. German schools trained students to be better citizens

C. American schools were not as good as German schools

D. the easy life in the American school was more helpful to students

Microsoft founder Bill Gates said that he planned to give away almost all of his vast^① fortune, largely to the cause of global health, during the course of his lifetime. With an estimated^② worth of more than $ 40 billion, according to Forbes, the project will be no small feat^③ for Gates. Having already provided the Bill & Melinda Gates Foundation with $ 24 billion to address global health issues, Gates said that eventually his entire fortune will be put towards the cause except “a few percent left for the kids.”

So what has made the richest man in the world to channel his resources so heavily into one interest? Gates believes that “the equality of opportunity” in which Americans take such pride needs to extend to other nations around the world. Improving the health of the populations, he says, has proven to be an essential method in helping poor countries to be financially^④ successful. “National borders allow inequalities,” said Gates, “We all need to take a more global view, rather than just saying my country is doing well. We have to step up these health issues, knowing how few resources are going into them.”

Gates said that both his parents set good examples to him as a child. His father, William H. Gates, was the head of the local Planned Parenthood, and his mother, Mary, volunteered for the United Way. As he gathered his fortune, Gates knew he would eventually want to give back as well, but he didn’t expect to devote himself whole-heartedly to one project until he was about 60.

However, Gates, 47, began to question his ability to wait that long. “It seemed there was a real time urgency,” Gates said, “I started to think, how many lives could I save before then?”

Notes:

vast adj. 巨额的

estimate v. 估计，估价

feat n. 功绩，壮举

financially adv. 财政上，金融上
