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(道德) 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 be 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% 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.

名校课堂系列答案It happened to me recently that I was telling someone how much I had enjoyed reading Barack Obama’s Dreams From My Father and how it had changed my views of the current US President. The person I was talking to agreed with me that it was, in his words, “a wonderfully written book.” However, he then proceeded to talk about Mr. Obama in a way that suggested he had no idea of his background at all. I sensed that I was talking to a book liar(说谎者)．
And it seems that he is not the only one. Clearly two thirds of people have lied about reading a book which they haven’t. In The World Book Day survey, Dreams From My Father is at number 9. The survey lists top ten books, and various authors, which people have lied about reading. As I’m not one to lie too often, I’ll admit here and now that I haven’t read the entire ten books. But I am pleased to say that I have read the book at number one, George Orwell’s 1984. I think it’s absolutely outstanding．
Asked why they lied, the most common reason was to impress someone they were speaking to. This could be difficult if the conversation became more in-depth!
The World Book Day survey also has some other interesting information in it. It shows that many people lie about having read classical works by Jane Austen, the Bronte sisters, Charles Dickens and so on. But when asked which authors they actually enjoy, they named JK Rowling, Jilly Cooper, and Stephen King. Forty-one percent of people asked admitted they turned to the back of the book to read the end before finishing the story．
So which books have you lied about reading —if any — and which is your favorite?
【小题1】The main reason why people lie about reading is to __________.
| A．make fun of the listener | B．impress the listener |
| C．please the listener | D．interest the listener |
| A．wanted | B．happened | C．continued | D．stopped |
| A．Are You A Book Liar? | B．Readers Are All Liars |
| C．World Book Day | D．Dreams From My Father |
