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： Dr. Allen Hersh designs smells for businesses. He says that it doesn't take a whole lot of smell to affect you. (29) Store owners can lure you to the candy aisle, even if you don't realize you are smelling candy. This idea scares a lot of peoplE.Groups that protect the rights of shoppers are upset.They say the stores are using a kind of brainwashing which they call 'smell-washing'. 'It's pretty dishonest,' says Mark SilbergelD.He runs an organization that checks out products for consumers. The scientists hired to design the scents disagreE.(30) 'There's soft background musiC.There's special lighting. There're all sorts of bells being used,' says Dr. Hersh, 'why not smells?' 'One reason why not,' says Silbergeld, 'is that some people are allergic to certain scents pumped into products or stores.'But there is a whole other side to this debate, 'do the smells really work?' So far, there is little proof one way or the other. But Dr. Hersh has run some interesting experiments. In one of Hersh's experiments, 31 volunteers were led into a shoe store that smells slightly like flowers. Later, another group shopped in the same store, but with no flower odor. (31) Dr. Hersh found that 84% of the shoppers were more likely to buy the shoes in the flower-scented room, but Hersh found out something even stranger. 'Whether the volunteers like the flower scent or not didn't matter,' Hersh says, 'Some reported that they hated the smell, but they still were more likely to buy the shoes in the scented room.'Questions:Why are some people against the use of smells to attract customers?What is Dr. Hersh's attitude to the use of smells for business?What did Hersh's experiment show?(30)A.Customers may get addicted to the smell.B.Customers may be misled by the smells.C.It hides the defects of certain goods.D.It gives rise to unfair competition.
