9、ult mammal.The clone, named Dolly, is a sevenmonthold sheep, grown from a cell of an adult female sheep.What is a clone？A clone is a copya genetic copy.Genes are the instructions for life.They tell a cell what to do and how to do it.Genes make each individual plant or animal different and unique.But
10、 a clone has the same genes as the original organism (生物体).Cloning is not new.Plants have been cloned for centuries.New plants are often grown from cutting from another plant.Also, plants like pineapples, strawberries and carnations (康乃馨) are sometimes cloned.One benefit of cloning is that we can ma
11、ke many copies of the best and healthiest plants.It has been much more difficult to clone animals.Frogs have been cloned, but they died as tadpoles, never living long enough to become adult frogs, which made the scientists despondent.Mice, sheep and cattle have been cloned from embryos.But Dolly is
12、the first healthy clone of an adult mammal.How did they do it?(1)An unfertilized egg was taken from a sheep.(2)The egg nucleus was removed.(3)A cell was taken from the udder (乳房) of a pregnant sheep.It was “starved”， so that it stopped growing.(4)The two cells were combined into one, and then implan
13、ted it in a third sheep, where it grew normally.(5)The clone was born.It was genetically identical to the pregnant sheep.This sounds much easier than it actually was.To end up with one clone, the scientists started with 277 udder cells.And they needed a way to make the egg cell accept a new nucleus.
14、They did that by starving the cell.It may soon be possible to clone many types of animals.Will we also be able to clone human organs, or even whole human beings？We have only begun to think about the morality of cloning technology.Maybe the question to ask is not whether we can clone humans, but inst
15、ead, should we clone humans?1.What can replace the underlined word “despondent” in the fourth paragraph?A.calmed downB.set downC.cut down D.cast down解析词义猜测题。由第四段前两句可推知科学家们很不高兴。cast down“使沮丧；使不愉快”。答案D2.According to the passage we can know that_.A.only plants can be clonedB.only strawberries and carna

22、However, in general the scientists were praised for their wonderful scientific breakthrough.The Scottish scientist, Ian Wilmut, is shocked that some scientists are now considering cloning human beings.Although he researches cloning, his intention has never been to create copies of humans.Instead, he
23、 thinks research efforts should concentrate on creating new tissue and organs that could eventually be used to cure diseases like cancer.However, some people consider that cloning human embryos with the intention of destroying them shows no respect for human lives.While cloning human embryos is ille
