With the repid development of technology, clone comes to the world. It can duplicate creature, which means it can make contribution to the production. People can pay a little and get a lot in the end. However, it also has disavantages. I think as the development of the high-tech, people can use clone to copy humen beings.

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 (胚胎) carrying Missy’s DNA. None have survived the transfer to a surrogate mother. The wastage of eggs and the many spontaneously aborted 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 clone
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 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. 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?

Today’s technology develops so quickly that many impossible things become true; the cloning technology is the example. What is cloning? Cloning is a process used to create an exact copy of a mammal by using the complete genetic material of a regular body cell. Different from the common propagate, cloning need only one cell and without sex. In 1997, the great news shocked the whole world that the British scientists created a lamp named Dolly from a single cell, miraculously; the cell had been taken from the udder of adult sheep, which show the first cloning experiment was successful.
When the cloning technology improves so quickly, many scientists and doctors have different opinions, someone think it is good but someone think it is bad. Cloning can bring many benefits to the human, such as rejuvenation, helpful for Defective genes, Liver failure, Kidney failure and Leukemia. These disease are very different to cure, if we use the cloning technology we can change the Gene’s DNA order, so we can save lots of people. But cloning still has some problems. The scientists found that the cloning animal’s Gene has a little different from the original animal. So the life will shorter than the real life. The fact proved that, the cloning sheep Dolly has died. It only has the half life of the com
mon sheep.In my own opinion I agree to clone the endangered animal and disagree with cloning human. Because I think the cloning technology should be respected. It really can bring us many benefits; further more it can develop the science of human. If clone the human, there will, however, be many problems, the population is the biggest problem. May be some people will use the cloning people to start the war. So I am against cloning human.
