Scientist Says ‘No’ to Human Cloning
“I’ve never met a human worth cloning,” says cloning expert Mark Westhusin from his lab at Texas A&M University. “It’s a stupid endeavor.”
That’s an interesting choice of adjective, coming from a man who has spent millions of dollars trying to clone a 13-year-old dog named Missy. So far, he and his team have not succeeded, though they have cloned two cows and a cat.
They just might succeed in cloning Missy soon — or perhaps not for another five years.
Westhusin's experience with cloning animals leaves him upset by all this talk of human cloning. In three years of work on the Missy project, using hundreds upon hundreds of dog's eggs, the A&M team has produced only a dozen or so embryos carrying Missy's DNA. None have survived the transfer to a surrogate(代孕的)mother. The wastage of eggs and the many spontaneously aborted(流产,发育不全) fetuses(胎)may be acceptable when you're dealing with cats or bulls, he argues, but not with humans. “Cloning is incredibly inefficient, and also dangerous,” he says.
Even so, dog cloning is a commercial opportunity, with a nice research payoff. Ever since Dolly the sheep was cloned in 1997, Westhusin's phone has been ringing with people calling in hopes of duplicating their cats and dogs, cattle and horses. “A lot of people want to clone pets, especially if the price is right,” says Westhusin. Cost is no obstacle for Missy's mysterious billionaire owner; he's put up $3.7 million so far to fund A&M's research.
Contrary to some media reports, Missy is not dead. The owner wants a twin to carry on Missy's fine qualities after she does die. The prototype(原型;雏形)is, by all accounts, athletic, good-natured and supersmart. Missy's master does not expect an exact copy of her. He knows her clone may not have her temperament(气质、性情). In a statement of purpose, Missy's owner and the A&M team say they are “both looking forward to studying the ways that her clones differ from Missy.”
Besides cloning a great dog, the project may contribute insight into the old question of nature vs. nurture. It could also lead to the cloning of special rescue dogs and many endangered animals.
However, Westhusin is cautious about his work. He knows that even if he gets a dog pregnant, the offspring, should they survive, will face the problems shown at birth by other cloned animals: abnormalities like immature lungs and heart and weight problems~ “Why would you ever want to clone humans,” Westhusin asks, “when we're not even close to getting it worked out in animals yet?”
【小题1】By “stupid endeavor”, Westhusin means to say that ________.
A.human cloning is a foolish undertaking |
B.animal cloning is absolutely impractical |
C.human cloning should be done selectively |
D.animal cloning is not worth the effort at all |
A.Its success is already in sight. |
B.It is progressing smoothly. |

D.examine the reproductive system of the dog species |

He came into the room to shut the windows while we were still in bed and I saw he looked ill. He was shivering, his face was white, and he walked slowly as though it ached to move.
“What's the matter, Schatz?”
“I've got a headache.”
“You better go back to bed.”
“No. I'm all right.”
“You go to bed. I'll see you when I'm dressed.”
But when I came downstairs he was dressed, sitting by the fire, looking a very sick and miserable boy of nine years. When I put my hand on his forehead I knew he had a fever.
“You go up to bed,” I said, “You're sick.”
“I'm all right,” he said.
When the doctor came he took the boy's temperature.
“What's is it?” I asked him.
“One hundred and two.”
Downstairs, the doctor left three different medicines in different colored capsules with instructions for giving them. One was to bring down the fever, another a purgative(泻药), the third to overcome an acid condition. The germs of influenza(流感)can only exist in an acid condition, he explained. He seemed to know all about influenza and said there was nothing to worry about if the fever did not go above one hundred and four degrees. This was a light epidemic(传染病;传染性的) of flu and there was no danger if you avoided pneumonia(肺炎).
Back in the room I wrote the boy's temperature down and made a note of the time to give the various capsules.
“Do you want me to read to you?”
“All right. If you want to, “ said the boy. His face was very white and there were dark areas under his eyes. He lay still in the bed and seemed very detached(超然的;冷漠的)from what was going on.
I read aloud from Howard Pyle's Book of Pirates(海盗);but I could see he was not following what I was reading.
“How do you feel, Schatz?” I asked him.
“Just the same, so far,” he said.
I sat at the foot of the bed and read to myself while I waited for it to be time to give another capsule. It would have been natural for him to go to sleep, but when I looked up he was looking at the foot of the bed, looking very strangely.
“Why don't you try to sleep? I'll wake you up for the medicine.”
“I'd rather stay awake.”
After a while he said to me, “You don't have to stay in here with me, Papa, if it bothers you.”
“It doesn't bother me.”
“No, I mean you don't have to stay if it's going to bother you.”
I thought perhaps he was a little lightheaded and after giving him the prescribed capsules at eleven o'clock I went out with my gun and the young hunting dog….I killed two quail(鹌鹑), and missed five, and started back pleased to have found a covey of quail close to the house and happy there were so many left to find on another day.
At the house they said the boy had refused to let anyone come into the room.
“You can't come in,” he said. “You mustn't get what I have.”
I went up to him and found him in exactly the position I had left him, white-faced, but with the tops of his cheeks flushed(发红)by the fever, staring still, as he had stared, at the foot of the bed.
I took his temperature.
“What is it?”
“Something like a hundred,” I said. It was one hundred and two and four tenths.
“It was a hundred and two,” he said.
“Who said so?”
“The doctor.”
“Your temperature is all right,” I said. “It's nothing to worry about.”
“I don't worry,” he said, “but I can't keep from thinking.”
“Don't think,” I said. “Just take it easy.”
“I'm taking it easy,” he said and looked straight ahead, He was evidently holding tight onto himself about something.
“Take this with water.”
“Do you think it will do any good?”
“Of course it will.”
I sat down and opened the Pirate book and began to read, but I could see he was not following, so I stopped.
“About what time do you think I'm going to die?” he asked.
“What?”
“About how long will it be before I die?”
“You aren't going to die. What's the matter with you? “
“Oh, yes, I am, I heard him say a hundred and two.”
“People don't die with a fever of one hundred and two. That's a silly way to talk.”
“I know they do. At school in France the boys told me you can't live with forty-four degrees. I've got a hundred and two.”
He had been waiting to die all day, ever since nine o'clock in the morning.
“You poor Schatz,” I said. “Poor old Schatz. It's like miles and kilometers. You aren't going to die. That's different thermometer. On that thermometer thirty-seven is normal. On this kind it's ninety-eight.”
“Are you sure?”
“Absolutely,” I said, “It's like miles and kilometers. You know, like how many kilometers we make when we do seventy miles in the car?”
“Oh,” he said.
But his gaze at the foot of the bed relaxed slowly. The hold over himself relaxed too, finally, and the next day it was very slack(松驰的) and he cried very easily at little things that were of no importance.

Tsai Chin Chung is one of Taiwan’s most famous cartoonists, and his cartoons are enjoyed by people in many different countries in Asia. His books of cartoons have now become best sellers in Singapore, Malaysia, and even Japan.
As soon as he could hold a pencil, Tsai Chin Chung lived only for drawing. Every day he practised drawing people and things around him and from his favorite stories.
When he was only 15 years old, he left home to work for a publisher in Taipei. He worked hard to draw pictures for books. Two years later, he left his job and started to work on drawing cartoon series, which he liked better. He made up his mind to succeed as a cartoonist.

Ten of these are about ancient Chinese philosophers based on Chinese historical and literary classics.
