第二部分 阅读理解（共20小题：每小题2.5分，满分50分）
阅读下列短文，从每题所给的四个选项A、B、C、D四个选项中，选出最佳选项。
A very important world problem---- in fact, I tend to say it is the most important of all the great world problems which face us at 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 the most important. It works out to be about 1.6 percent net annual increase. In terms of numbers this means something like 40 to 55 million additional people very year. Canada has a population of 20 million, rather less 6 months’ climb in world population. And there are 10 million people in Australia. So, it takes the world less than three moths to add to itself a population, a population of that vast country. Let us come to our own crowded country---- England and Wales; 45--50 million people---- just about a year’s 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 city of York.
I am not talking about birthrate. This is net increase. To give you some idea of birthrate, 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 birthrate.
This enormous increase of population will create immense problems. By 2010 A. D., unless something desperate happens, there will be as many as 7,000, 000, 000 people on the surface of this earth! So this is a problem which you are going to see in your lifetime.
