Every human being has a unique (唯一的) arrangement of the skin on his fingers and this arrangement is unchangeable. Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the cage.
The ridge (脊状) structure on a person's fingers does not change with growth and is not affected by surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one which bears a reproduction of the original pattern. It is only when the inner skin is injured that the arrangement will be destroyed. Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take.
Finger-prints can be made very easily with printer's ink. They can be recorded easily. With special methods, identification (识别) can be achieved successfully within a short time. Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal case. A suspected man may deny a charge but this may be in vain. His finger-prints can prove who he is even if his appearance has been changed by age or accident.
When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye. Special techniques are used to "develop" them. Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained.

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 author thinks human cloning is wrong mainly for ______ reasons.

| B．there are 200 sheep successfully cloned. |
| C．cloning means running the risk of wasting too much effort |
| D．numbers of baby animals are likely to be created by cloning |

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.

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.
