山西省长治市2016高考英语（二轮）阅读理解精练（2）阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。Recently there was a major discovery in the scientific researchthe 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 cant 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 disappea. 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 havent 100 percent. guaranteed that the first cloned 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.9.Which of the following is true according to the passage？ A.

Ive never watched her show, but when a self-made billionaire gives life advice its probably worth listening to.Her point is that blind luck is very rare. You may have to be lucky to find a good job these days but that does not mean you should sit at home waiting for the opportunity to come to you. If youre a Chinese, you may already be familiar with the tale of a farmer waiting by a tree stump(树桩) for a rabbit to run out and break its neck.A book by the UK psychologist Richard Wiseman, called The Luck Factor, argues we can all make ourselves luckier. Its not about going to a temple to burn some incense(香) hopes that the gods will give you good fortune; its practical advice you can follow each day.Wiseman conducted an experiment as part of his studies. First he divided volunteers into two groups; those who said they were lucky in life and those who said they were not. He gave everyone a newspaper and asked them to look through it to count how many photographs it had inside. On average, the unlucky people took about two minutes to count the photographs while the lucky people took just seconds. Why? On the second page of the newspaper, a command, “Stop counting. There are 43 photographs in this newspaper,” was written in big letters. The unlucky people mostly did not spot the message.Its easy to compare this situation to a young person looking for jobs in a local paper. They might search so hard for one type of position that they miss an even
