听力原文：Human cloning involves creating an embryo out of a cell taken from a fully developed human being. "Reproductive" cloning means growing an embryo into a second, genetically identical human being. "Therapeutic" cloning, by contrast, means using an embryo as a source of stem cells for the person who supplied the originally cell. The theory is that stem cells with DNA identical to yours would be more likely to develop successfully into replacement parts for you. Brain cells for people with Parkinson's are the most promising example, but ultimately even severed limbs might grow back this way.

Which of the following statement is NOT true of therapeutic cloning?

A．Therapeutic cloning is used mainly for research purposes and therefore should be allowed to continue.

B．Therapeutic cloning is used for medical purposes and not for reproducing full human beings.

C．Therapeutic cloning is used for replacing the diseased parts of human organs.

D．Brain cell can be used in the future to cure the Parkinson's disease.

听力原文：M: I've been reading about a new healthful fast food. It's made from fish. Have you heard anything about it?

W: No, I haven' t. But I don't like fish very much anyway.

M: Not to worry. Although it is made primarily from fish, it actually doesn't have a fishy taste. In fact, it can be flavored with tomato, cheese, or chocolate, for instance.

W: How could it not taste fishy? Do you know bow this fast food is made?

M: First, the fish is minced to pieces, and cooked. Then, water, flour and flavor are added to make it into cakes.

W: It sounds awful. But I suppose this product will at least be good for one's health.

M: Yes, it is. And it has a long shelf life, so it won't spoil quickly. It is also easy to digest.

W: Hm, have you got any .samples? I might be willing to try the cheese-flavored variety.

M: No, none of these seem to be available yet. As I understand it, this fish fast food probably won't be in the store for another couple of years. So you have a while to get used to the whole idea.

W: Er, a couple of years, ha? It may just take me that long, but thanks for telling me about it.
