听力原文：W: Hi, Professor Smith. I hear you've written a book titled Visions.
M: Yes. It explains how science will revolutionize the 21st century.
W: Could I ask you some questions concerning the book？
M: Sure!
W: Are you optimistic about the future？
M: Generally, yeah! If we go back to the year of 1900, (22) most Americans didn't live beyond on the age of 50. Since then, we've had improvements in health care and technology. There's no reason why this won't continue far into the 21st century.
W: Are we ready for the changes that will come？
M: Changes are already happening. The future is here now. We have DNA, micro-chips, the internet. Some people's reaction is to say we are too old, we don't understand your technology. (23) My reaction is to say we must educate people to use new technology now.
W: Is world population going to be a big problem？
M: Yes and no. (24) I think that world population will stop increasing as we all get richer. If you are part of the middle class, you don't want or need twelve children.
W: Will there be a world government？
M: Very probably. We have to manage the world and the resources on the global level because countries alone are too small.
W: Will we have to control over everything？
M: I think we'll learn to control the weather, volcanoes and earthquakes, illness won't exist, we'll grow new livers, kidneys, hearts and lungs like spare parts for a car. People will live to about 230 or about 250. (25) For 2000 years, we have tried to understand our environment. Now we will begin to control it.

听力原文：W: Good morning
M: Good morning.
W: Well, what are your predictions about the world？ What is it going to be like in the year 2020？
M: Hum, if present trends continue, I'm afraid the world in 2020 will be more crowded and more polluted than the world we live in now.
W: Don't you think we will be able to cope with the increase in world population？
M: I don't think so. Even though production is constantly increasing, the people of the world will be poorer than they are today. For hundreds of millions of the desperately poor, the supply of food and other necessities of life will not be any better. And for many they will be worse, unless the nations of the world do something to change the current trends.
W: What is your estimate of world population in the year 2020？
M: If present trends continue, that is with the number of births by far exceeding the number of deaths. In 2020 the world population could approach 6,500 million people.
W: How many people are born every day？
M: About 250 every minute, but only 100 people die!
W: That's worrying! Will there be enough oil to satisfy our needs in the year 2020？
M: During the 2000s, world oil production will reach the maximum and the price of oil will begin to increase. At the next ten years of the century, the available supplies will not be sufficient for our needs. So, at lest part of these needs will have to be met by alternative sources of energy.
W: Well, that's a warning that we all need to take seriously. And with that warning, we end part one of this week's.
(23)
A．Increase food production.
B．Increase oil production.
C．Birth control.
D．All of above.
听力原文：W: In Britain we are often told that people are leaving the big cities to live in the countryside but is this tile case worldwide？
M: Not at all. If you look at the biggest cities in 1950, seven out of the top ten were in the developed countries. However, by the year 2000, the developing countries will have eight out of the top ten.New York, which in 1950 was number one with a population of around 12 million, will only be the sixth largest city in the world with an extra of 2 million.
W: And London？
M: London, which was number two, won't even be in the top ten. Its population in 1950 was about 10 million.
W: Why is this happening？ Why are people moving to tile big cities from the country in developing countries？
M: The reasons are complex but many are moving to look for jobs. And the problems this creates are enormous. Just imagine the kinds of difficulties this is going to cause in terms of health, transport and education.
W: Yes. What about the cities of Asia？ Will they be experiencing a similar sort of growth？
M: In some cases, yes. Calutta in India which was No. 10 in the league in 1950 is expected to be the fourth biggest city in the world with a population of 16 million, four times in its size in just 50 years.
W: What about Japan？
