Reading Comprehension

　　Cloning technology made its first leap from science fiction to science fact in 1997. That year, Scottish researcher lan Wilmut created the world's first animal clone：a sheep named Dolly. In making Dolly, Wilmut defied(对…挑战) nature because Dolly was produced without the union of male and female sex cells.

The method that Wilmut used to create Dolly is neither a top-secret nor hard to understand. First, he removed an egg cell from an adult female sheep. Then, he used a fine needle to suck out(吸出) the egg' s nucleus(细胞核), the structure that houses a cell' s DNA(deoxyribonucleic acid(脱氧核糖核酸). DNA contains the biological material that determines what an organism looks like and how it functions.

　　Next, Wilmut removed a skin cell from another sheep－the sheep he wished to copy. Placing the empty egg cell and the skin cell side by side, he forced the two cells to fuse by zapping(用辐射线照射) them with a charge(电荷) of electricity. By doing that, Wilmut created an egg from one animal that contained the DNA of another.

　　The new egg cell divided and developed into an embryo(胚胎). Wilmut then implanted(移植) the embryo in he womb(子宫). In time, the embryo developed into a lamb sheep－Dolly.

　　For years later, a whole barnyard of animal clone, including sheep, mice, cows, pigs, and goats, has, come to life in labs around the globe. Now, the race is on how to produce the first human clone although many people are strongly against it.

Tony: These days, the word "clone" has appeared very often in the newspapers. Do you  know its meaning?

Lana: I read a report. It said that Dr.-Ian Wilmut successfully cloned a lamb named Doily from a grown-up sheep .So people call him the "father" of Dolly.

Tony: In fact, the word "clone" means to produce the "same" animal by taking cells from a grown-up one. I think, if we know how to do cloning, we need only to keep a small number of sheep, cows or horses.

Lana: What's more, these days some people even want to clone humans. They have asked:  Can we clone ourselves?

Tony: It seems interesting. But do you think it possible to do that?

Lana: No, impossible! First, I think we cannot clone a dead person, because the cells in his body are dead already.

Tony：Then can we clone a living person?

Lana：Again no! You might clone yourself one after another, but it is only a copy, not a real you．It is only something，not a“human”．

Tony：Well，you mean that it is not a real human．

Lana：True enough! l think Dr．Wilmut would most like to make better animals，and it has nothing to do with human cloning．

    C．Dr. lan Wilmut takes care of Dolly like a father

    D．Dr. lan Wilmut has a daughter whose name is Dolly

A．Scientists have successfully cloned humans．

B．Dr．Wilmut likes to do human cloning

C．Cloned animals are better than grown-up ones．

D．Lana thinks humans shouldn’t be cloned．
