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.

June 12, Sunday, Fine
Today is Sunday. I didn't get up early as usually. In the morning after I finished my home-work, I do some washing. Then I telephoned one of my classmate and invited him to see a film. And unfortunately, when we got to the cinema at 3:00 p.m. we found all the tickets had sold out. So we went to our school and played the football. After that, when we were about to go home, we saw our English teacher, Mr. Wang, came into the school gate. He told us we had made many progress in English this term. He also suggested that we should read more and wrote more. We promised that we would take his advices.
Like distance runners on a measured course，all of us will move through time in a roughly predictable pattern．
In the first stage of our lives，we develop and grow, reaching toward the top of physical vitality(活力)．
After we grow up，however, the body begins a process of gradually wearing out．
A new awareness of physical fitness may help lengthen our years of health and vitality，yet nothing we do will work to stop the unavoidable force of aging．
Most of the changes of aging take place deep inside the body．The lungs become less able to take in oxygen．Powerful muscles gradually lose their strength．The heart loses power and pumps less blood．Bones grow easier to break．
Finally, we meet a stress，a stress that is greater than our physical resistance．Often，it is only a minor accident or chance infection(a disease caused by virus)，but this time，it brings life to an end．
In 1932，a classic experiment nearly doubled the lifetime of rats，simply by cutting back the calories in their diet The reason for the effect was then unknown．
Today, at the University of California at Berkley, Dr．Paul Seagle has also greatly lengthened the normal lifetime of rats．The result was achieved through a special protein limited diet，which had a great effect on the chemistry of the brain．Seagle showed that within the brain，specific chemicals control many of the signals that influence aging．By changing that chemical balance，the clock of aging can be reset．
For the first time, the mystery of why we age is being seriously challenged．Scientists in many fields are now making striking and far-reaching discoveries．
An average lifetime lasts 75 years，yet in each of us lies a potential for a longer life．If we could keep the vitality and resistance to disease that we have at age twenty, we would live for 800 years．
1.What does the underlined word “it” refer to?
A．Physical vitality． B．Stress． C．Aging． D．Physical resistance．
2.Which of the following is not a change of aging?

D．The lungs become unable to take in oxygen．zxxk

A．human's life pattern is predictable

4.How did Dr．Paul Seagle lengthen the lifetime of rats in his experiment?
A．By keeping their physical fitness． B．By cutting the calories in their diet．
C．By resetting their clock of aging． D．By limiting the protein in their diet．
5.What is probably the best title for the article?
