For q

2、uestions 1-7, choose the best answer from the four choices marked A), B), C) and D). For questions 8-10, complete the sentences with the information given in the passage.Using Land WiselyA very important world problem-in fact I am inclined to say it is the most important of all the great world probl

3、ems which face us at the present time-is the rapidly increasing pressure of population on land and on land resources.It is not so much the actual population of the world but its rate of increase which is important. It works out to be about 1.6 per cent per annum net increase. In terms of numbers thi

4、s means something like forty to fifty-five million additional people every year. Canada has a population of twenty million-rather less than six months climb in the world population. Take Australia. There are ten million people in Australia. So, it, takes the world less than three months to add to it

5、self a population which peoples that vast country. Let us take our own crowded country-England and Wales: forty-five to fifty million people-just about a years supply.By this time tomorrow, and every day, there will be added to the earth about 120,000 extra people-just about the population of the ci

6、ty of York.I am not talking about birth rate. This is net increase. To give you some idea of birth rate, look at the second hand of your watch. Every second three babies are born somewhere in the world. Another baby! Another baby! Another baby! You cannot speak quickly enough to keep pace with the b

7、irth rate.Why is this enormous increase in population taking place? It is really due to the spread of the knowledge and the practice of what is coming to be called Death Control. You have heard of Birth Control? Death Control is something rather different. Death Control recognizes the work of the do

8、ctors and the nurses and the hospitals and the health services in keeping alive people who, a few years ago, would have died of some of the incredibly serious killing diseases, as they used to be. Squalid (肮脏的) conditions, which we can remedy by an improved standard of living, caused a lot of diseas

9、e and dirt. Medical examinations at school catch diseases early and ensure healthier school children. Scientists are at work stamping out malaria and other more deadly diseases. If you are seriously ill there is an ambulance to take you to a modern hospital. Medical care helps to keep people alive l

10、onger. We used to think seventy was a good age; now eighty, ninety, it may be, are coming to be recognized as a normal age for human beings. People are living longer because of the Death Control, and fewer children are dying, so the population of the world is shooting up.Imagine the position if you

11、and I and everyone else living on earth shared the surface between us. How much should we have each? It would be just over twelve acres-the sort of size of a small holding. But not all that is useful land which is going to produce food. We can cut out one-fifth of it, for example, as being too cold.

12、 That is land which is covered with ice and snow-Antarctica and Greenland and the great frozen areas of northern Canada. Then we can cut out another fifth as being too dry-the great deserts of the world like the Sahara and the heart of Australia and other areas where there is no known water supply t

13、o feed crops and so to produce food. Then we can cut out another fifth as being too mountainous or with too great an elevation above sea level. Then we can cut out another tenth as land which has insufficient soil, probably just rock at the surface. Now, out of the twelve acres only about four are l

14、eft as suitable for producing food. But not all that is used. It includes land with enough soil and enough rainfall or water, and enough heat which, at present, we are not using, such as, for example, the great Amazon forests and the Congo forest and the grasslands of Africa. How much are we actuall

15、y using? Only a little over one acre is what is required to support one human being on an average at the present time.Now we come to the next point, and that is, the haves and the have-nots amongst the countries of the world. The standard share per person for the world is a little over twelve acres

16、per head; potentially usable, about four acres; and actually used about 1.1 acre. We are very often told in Britain to take the United States as an example of what is done or what might be done. Every little American is born into this world with a heritage of the home country, the continental United

17、 States, of just about the world average-about twelve acres. We can estimate that probably some six acres of the total of twelve of the American homeland is cultivable in the sense I have just given you. But the amount actually used-what the Americans call “improved land“ in crops and pasture on far

18、ms-is three and a half acres. So the Americans have over three times the world average of land on which to produce food for themselves. On that land they produce more food than they actually require, so they have a surplus for export.Now suppose we take the United States great neighbor to the north,

19、 Canada. Every Canadian has 140 acres to roam around in. A lot of it is away in the frozen north, but there is still an enormous area of land in Canada waiting to be settled and developed. The official figure is twenty-two acres. The Canadians use at the moment four acres, and they too have a large

20、food surplus available for export.Now turn to our own country. Including land of all sorts, there is just over one acre per head in the United Kingdom of Great Britain and Northern Ireland. That is why we have to be so very careful with it. How much do we actually use? Just over half an acre to prod

21、uce food-that is as farm land. The story is much the same if you separate off Northern Ireland and Scotland and just take England and Wales. In this very crowded country, we have only 0.8 acres per head of land of all sorts to do everything with which we need. That is why we have to think so very ca

22、refully of this problem.（分数：70.00）(1).According to the passage, the most important problem in the present world is _.
