I’m sure many of you have seen Star Wars, Jurassic Park, Multiplicity, or many of the other movies that describe cloning. Most of what you see in these movies is false. What you don’t know is that cloning could be dangerous, to the clone and to our society as a whole. I think human cloning is wrong mainly for four reasons.
What about identity? Humans are promised the right to their own personalities. What would happen if we ignore those rights by giving them someone else’s genetic identity? True, Cloning may prevent people from possessing their identities.
Also, these is a large power struggle here. Cloning means a degree of power and controls over another person’s physical identity and that ignores their rights and their only personalities. The person doing the cloning would have more power than any parent would have.
Cloning would also deal with killing embryos (胚胎). You might not have known, but Dolly, the sheep that was cloned in 1996, was one of over 200 sheep embryos and hers was the only embryo that survived. The rest died or were thrown away. Imagine if the failure rate was that high when we started to clone humans. cloning means running the risk of wasting too much effort
Cloning someone, at this present time, would be extremely dangerous to the birth mother and the clone. In studies done on cows, 4 out of 12 birth mothers died. There is a very high failure rate, which is shown in the cloning of Dolly. Even if you had a few good embryos, failures have been noticeable in animal tests.
So, should we work ahead in the world of cloning? I say no. the risks are greater than the benefits. It’s dangerous to the clone and to the birth mother. We would be killing human lives in the process. It would also be a violation(侵害) of the clone’s right to its own genetic identity and personality.

The differences between men and women's friendships
Betty and Harold have been married for years. But one thing still puzzles (困扰) old Harold. How is it that he can leave Betty and her friend Joan sitting on the sofa, talking, go out to a ballgame, come back three and a half hours later, and they're still sitting on the sofa and talking?
What old Harold cannot understand or explain is the fact that women have so much to share.
Betty shrugs. Talk? We're friends.
Researching this matter called friendship, psychologist Lillian Rubin spent two years interviewing more than two hundred women and men. the results were completely clear: women have more friendships than men. Rubin's study shows that for emotional support a married woman is more likely to turn to a female friend.
"In general," writes Rubin in her new book, "women's friendships with each other lie on shared emotions and support, but men's relationships are marked by shared activities.”
“ Men keep their innermost(内心深处的) feelings to themselves. " Rubin writes, " Whereas(然而) a woman's closest female friend might be the first to tell her to leave a failing marriage. However, a man by society doesn’t complain about his marriage trouble. it wasn't unusual to hear a man say he didn't know his friend's marriage was in serious trouble until he appeared one night asking if he could sleep on the sofa.

In today's world, almost everyone knows that air pollution（污染）and water pollution are harmful to people's health. However, not all the persons know that noise is also a kind of pollution, and that is harmful to human health, too.
People who work and live under noisy conditions usually become deaf（聋）. Today, however, scientists believe that 10 percent of workers in Britain are being deafened by the noise where they work. Many of the workers who print newspapers and books, and who weave（织）cloth become deaf. Quite a few people living near airports also become deaf. Recently it was discovered that many teenagers（几十岁的人）in America could hear no better than 65-year-old persons, for these young people like to listen to pop music and most of pop music is a kind of noise. Besides, noise produced by jet planes or machines will make people's life difficult and unpleasant, or even make people ill or even drive them mad.
It is said that a continuous noise of over 85 decibels（分贝）can make people deaf. Now The governments in many countries have made laws to control noise and make it less than 85 decibels. In China, the government is trying to solve not only air and water pollution problems but also noise pollution problems.

Nowadays, with the development of science and technology, cloning has become a hot topic for many people. Some people are against it ,while others are in favour 48 it. Personally, I wouldlike to say that cloning is good 49 the human race.
50 , cloning technology proves helpful for genetics researchers. With cloning technology, scientists 51 bring some animals that are extinct back to life. Secondly, cloning body parts can serve as a lifesaver for people 52 are seriously ill. When a body organ such as a kidney or heart fails to function, it may be possible to replace it 53 a cloned one. Thirdly, if a couple can’t have 54 child, human cloning technology will make it possible for them to have a child. All in all, I firmly believe that cloning is beneficial 55 the human race.
The friendship between us never fades. Mary Allen was my best friend—like a sister I never had. We did everything together: piano lessons, movies, swimming, horseback riding, and so on.
When I was 13, my family moved. Mary and I 36 in touch through letters, and we saw each other on special 37 — like my wedding and Mary’s. Soon we were 38 with children and moving to new homes, and we wrote less. One day a card that I sent came back, 39 “Address Unknown.” I had no idea how to 40 Mary.
Over the years, I thought of Mary often. I wanted to 41 stories of my children and then grandchildren. I need to share my 42 when my brother and then my mother died. There was an empty place in my heart that only a friend like Mary could 43 .
One day I was reading a newspaper 44 I notice a picture of a young woman who looked a lot like Mary and whose last name was Wagman— Mary’s married name. “There must be thousands of Wagmans,” I thought, 45 I wrote to her anyway.
She called as soon as she got my letter. “Mrs. Tobin!” she said excitedly, “Mary Allen Wagman is my mother”. Minutes later I heard a voice that I 46 at once, even after 40 years. We laughed and cried and asked about each other’s 47 .
Now the empty place in my heart is filled, and there is one thing that Mary and I know for sure: We won’t lose each other again!
