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．

69．Where can you read this article?

　　　 A．In a story book．

　　　 B．In a magazine．

　　　 C．In a science fiction．

　　　 D．In a brochure．

70．Which of the following shows the structure of the passage?

Impossible cases are not forever. While it is impossible for one person, it is possible for another. In a word, everything is possible.
Someone says, "Success belongs to those who can look at the complex challenges offered by the world as inspiration." So your challenges are golden opportunities for success. How can there be miracles if there are no obstacles? How will you chase the storm if there is no storm? You need challenges to reveal your ability. Success doesn’t come out’ of nothing; success comes from the problems you face. Those who refuse to give in
come out smiling.
Robert X. Perez says, "The seeds of success spring from failure’s ashes. "Failure is not defeat; it is the pointer to do better than what you just did. You have to know that you are in a constant study of life. What you face is for your training. Samuel Aidoo says, "Each failure is simply another chapter in the story of our lives. To fail is to understand what not to do. Remember it and don’t give up until your goal is achieved."
What do you do when you face difficulty? Yeah, life is difficult, but you do not give up.
Have a positive and calm outlook on your circumstances (状况) and make the best of them. You may learn something new. You can develop mental toughness. Mental toughness means to be able to see the long-term gains rather than be put off by short-term pains. Once you have this toughness, you have the winning edge(优势).
The only things in life you ever really regret are the chances you didn’t take. You will regret when you see the consequences of not seizing the opportunities when they arose. Take chances every day!
【小题1】 The main point of the passage is that_________.
