Have you ever imagined that you could be cloned like Dolly the sheep in the not too distant future?
The news that a human embryo (胚胎) has been 1 cloned for the first time has caused mixed reactions (反映).
The 2 was carried out by scientists from the Advanced Cell Technology Inc (ACT), in Massachusetts, US. The group 3 the news on November 25.
“This is 4 human being. A clone is alive, it walks, it breathes,” said Jamie Grifo, 5 on the study of cloning at New York University School of Medicine.
“This is a set of cells in a lab that will be used to 6 someone's life. ”
Such research could lead to treatment for 7 such as heart diseases, AIDS and even cancer, 8 scientists.
Despite high hopes from other scientists, the news raised concerns immediately from religious and political leaders. Several 9 in the US do not allow human cloning. President George W. Bush also made it clear that he is 10 any type of human cloning. However, the scientists at ACT said they have no interest at present in 11 an early embryo into __12__.
Animals have been cloned repeatedly since Dolly the sheep 13 in 1997. And there were no real technical 14 to stand in the way of scientists making a cloned human embryo.
This time the research group used traditional cloning technology with a human 15
16 it was given DNA from an adult cell, the egg began to __17__.__18__ it was stopped from becoming a baby--at a stage in which it was 19 a ball of cells. The 20 technology has been used to clone sheep, cattle and monkeys.

British scientists have done something that，many people thought，was impossible: they created the first clone of an adult mammal（哺乳动物）．The clone，named Dolly，is a seven-month-old sheep，grown from a cell of an adult female sheep.
What is a clone? A clone is a copy—a 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 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 make 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 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(细胞核）was removed.
（3)A cell was taken from the udder(乳房）of a pregnant(怀孕的）sheep. It was“starved”，so that it stopped growing.
（4）The two cells were combined into one，and then implanted 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 in a way to make the egg cell accept a new nucleus. 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 instead，should we clone humans?
59. What can replace the underlined word“despondent” in the fourth paragraph?
A. calmed down B. set down
C. cut down D. cast down
60. Dolly is a sheep________because she is grown from a cell of an adult female sheep.
A. that has no father B. that has no mother
C. that has no parents D. that has no tail
61. According to the passage we can know that__________．
A. only plants can be cloned
B. only strawberries and carnations can sometimes be cloned
C. animals and plants have quite a long history of cloning
D. genes can tell a cell what to do and how to do it during cloning
62. From the fourth paragraph we can know that__________．
A. a tadpole is the early stage of a grown-up frog
B. a tadpole is a frog without a tail
C. a tadpole is a kind of animal
D. a tadpole is a clone of an adult mammal

As I understand, if scientists produced a human clone, there would be a great risk of it having a disease. Nobody seems to understand the ageing process of a clone. It would be terrible if a baby was the age of its parent at 31 . Its cells would grow old fast and it would die young. 32 until the technique is perfectly safe, it should be 33 .
I'd love to have a clone of 34 . I often wish I had a twin sister, someone who 35 me in everything. So why not a clone? Well, the idea 36 be fun but I'm not sure if it would be 37 . I think we would be playing with fire if we let scientists go ahead with 38 cloning. There are so many 39
involved that all research in this area should be strictly controlled.
There are so many arguments 40 cloning that it is difficult to get anyone to consider the possible benefits. I am 41 that it is a technique which could be beneficial. The most obvious use would be for childless 42 . They would be able to have babies with their own genetic material. I don't see what's wrong with that.
Imagine a child 43 up knowing that his or her mother is really a sister or a brother. The emotional 44 on the child would be 45 . Or a child who was cloned from a dead brother or sister. What kind of emotional pressure would they feel, knowing they were made as a replacement for another? The whole idea
46 me!
It's all very good to ban human cloning but scientists should be allowed to 47
research. If they don't, we may 48 important benefits for our society, such as producing body organs. A clone is an 49 copy of a person with the same gene. Therefore, it is the 50 donor for an organ(器官) transplant.
