| Text 2 A very important world problem — in fact, I think it may be the most important of all the great world problems which face us at the present time — is the rapidly increasing pressure of population on the land. The population of the world today is about 4,000,000,000. That is an enormous number, yet it is known quite accurately, because there are very few parts of the world which have not carried out a modem census. The important thing is not so much the actual population of twenty million — about six months’ increase in world population. Take Australia for example, there are ten million people in Australia. So it takes the world about three months to add to itself a population which peoples that vast country. Let us take our own crowded country, England and Wales — forty-five to fifty million people. This is just A. 40 million B. 4 billion C. 400 million D. 40 billion [单项选择]A very important world problem, if not the most serious of all the great world problems which affect us at the moment, is the increasing number of people who actually inhabit this planet. The limited amount of land and land resources will soon be unable to support the huge population if it continues to grow at its present rate.
In an early survey conducted in 1888, a billion and a half people inhabited the earth. Now, the population exceeds five billion and is growing fast—by the staggering figure of 90 million in 1988 alone. This means that the world must accommodate a new population roughly equal to that of the United States and Canada every three years! Even though the rate of growth has begun to slow down, most experts believe the population size will still pass eight billion during the next 50 years. So why is this huge increase in population taking place It is really due to the spread of the knowledge and practice of what is becoming known as "Death Control". You have n A. New inventions. B. Better hygiene. C. Improved food production. D. Better control of fatal diseases. 我来回答: 提交
