Recently there was a major discovery in the scientific research—the mapping of all DNA in a human gene（基因） is complete．Couple of years ago, this seems an impossible task for scientist to accomplish．All this progress in science leads us to believe that the day, when the human being will be cloned, is not far away．Human cloning has always been a topic of argument, in terms of morality or religion．
Taking a look at why cloning might be beneficial, among many cases, it is arguable that parents who are known to be at risk of passing a genetic limitation to a child could make use of cloning．If the clone was free of genetic limitations．then the other clone would be as well．The latter could foe inserted in the woman and allowed to ripen to term．Moreover, cloning would enable women, who can't get pregnant, to have children of their own．
Cloning humans would also mean that organs could be cloned, so it would be a source of perfect transfer organs．This, surely would be greatly beneficial to millions of unfortunate people around the world that are expected to lose their lives due to failure of single （or more） organ （s）．It is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the freedom of scientists．
Arguments against cloning are also on a perfectly practical side．Primarily, I believe that cloning would step in the normal "cycle" of life．There would be a large number of same genes, which reduce the chances of improvement, and, in turn, development—the fundamental reason how living things naturally adapt to the ever-changing environment．Life processes failing to do so might result in untimely disappearance．Furthermore, cloning would make the uniqueness that each one of us possesses disappear．Thus, leading to creation of genetically engineered groups of people for specific purposes and, chances are, that those individuals would be regarded as "objects" rather than people in the society．
Scientists haven't 100 per cent．guaranteed that the first cloned humans will be normal．Thus this could result in introduction of additional limitations in the human "gene-pool"．
Regarding such arguable topics in "black or white" approach seems very innocent to me personally．We should rather try to look at all "shades" of it．I believe that cloning is only legal if its purpose is for cloning organs; not humans．Then we could regard this as for "saving life" instead of "creating life"．I believe cloning humans is morally and socially unacceptable．
67．Which of the following is true according to the passage?
A．Genetic limitation will be beneficial for some women．
B．A large number of genes will prevent us from developing．         
C．Prohibition of cloning might limit the freedom of scientists．
D．First cloned humans might be normal according to scientists．
68．What's the author's opinion on cloning?
A．Cloning should be entirely banned．
B．Cloning should be used in creating life．
C．Cloning will take away the right to reproduce．
D．Cloning is acceptable if it is used for cloning organs．

A proverb(谚语) is a short , well-known saying that expresses a common truth or belief. Proverbs are popular around the world. Many proverbs give advice on how to live. Some proverbs are hundreds of years old, but they are still used today.

For example, my son is just like his father in many ways. We often say the two of them prove the proverb that the apple does not far from the tree.

My daughter is very short. She would like to be taller. But I tell her that good things come in small packages. Some valuable things are very small, like diamonds and other jewels. But I also tell my children that all that glitters is not gold. Something may look valuable, but may not really be valuable. Also, I tell them do not judge a book by its cover. You should not judge something only by its appearance.

Sometimes I tell my children to cooperate to solve a problem. After all, two heads are better than one. But another proverb says too many cooks spoil the soup. If too many people try to do something, then the job will not be done well.

I also tell my children that two wrongs do not make a right. You should not do something bad just because someone did the same to you.

Some people are pessimists while other people are optimists. Pessimists always think about how bad things are or will be; optimists might say that every cloud has a silver lining and they always look on the bright side. Other people are both pessimists and optimists. They hope for the best and prepare for the worst.

Some people often worry about what they will do in a situation that might happen in the future. We could tell them do not cross that bridge until you come to it.

It is usually much better to prevent a problem from happening than it is to find ways to solve it. So we say an ounce of prevention is worth a pound of cure.

63. The author often comforts her daughter with the proverb that ____.

A. the apple doesn’t fall far from the tree.

B. a problem will be solved easily by many people

C. jobs won’t be done well if there are too many people

D. you can’t do something bad even if someone else does it

A. who always look on the bright side

B. who always expect bad things to happen

C. who are always full of hope for the future

D. who always make preparations for the worst

66. Which of the following are optimists likely to say?
