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. 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(禁止) of cloning might limit the freedom of scientists |
| D．First cloned humans might be normal according to scientists |
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 |
Which of the following shows the structure of the passage
A couple of years ago, I received a $ 600 insurance dividend (保险股息).Sitting at the kitchen table, my wife and I discussed what we might do with the money.
I realized now that the refrigerator overheard our talk. The very next day it went wrong. The repairman told us we needed a new unit. Cost:$600. Not long after that, we got a refund（赔偿金）from the shop, enough to pay for a trip to Mexico. “I’ve something to tell you,” I said to my wife in a low voice. “How about the living-room?” she suggested. I remembered the color TV set was there. “No, not there. Let’s go out.” I showed her the check as we stood on the driveway. We held each other excitedly and hardly noticed the rain. My car was parked within5 meters. I didn’t think anything about it at the time. As I started for the airport the next day, the car began making strange sounds. Changing the engine cost about $ 1, 000.
Then I looked through our financial records. I discovered that during the last ten years we spent all our “found money” repairing a hot water heater, a television and a stove.
I never mention money in front of our mechanical equipment. But if this article is published and I am paid for, the word processor（文字信息处理机）is going to go for sure. It’ll know. What went wrong first as the writer’s?
| A．The refrigerator | B．The stove |
| C．The TV set | D．The engine of the car |
What has been repaired and still remains all right?
| A．The car | B．The color TV set |
| C．The stove | D．The hot water heater |
Which statement is wrong according to the passage?
s thingsWhat’s A Real Friend?
You can have the same neighbors for years．You love them or you think you love them．And you hope that they love you．But do you ever really understand them?
Charlie Kemp and his family lived next door to me for 15 years．We were good friends all the time．I enjoy friendship．I think it's the best thing in the world．And friendship with the Kemps was easy because they seemed to welcome it．
They were interesting and clever people．Their house caught fire twice, and twice the whole family slept in mine．They are always losing things like money, keys and watches．Pictures fell off the walls, the children fell out of bed …
I was their neighbor and their friend．Life was always interesting, never dull．Best of all, I liked the whole family．
One day, I lit a fire in the garden to burn some rubbish．After some time Charlie Kemp came out of his house and walked up the road．
“Morning, Charlie,” I said, “lovely day, isn’t it?” He smiled at me and nodded．I went on with my work．
Twenty minutes later, a policeman arrived．He walked into my garden and said, “You’ll have to put out that fire．Your neighbor has complained (抱怨) to us．He doesn't like the smell．”
“My neighbor …?” I asked．
“Yes,” the policeman took out his notebook and read, “Charlie Kemp．He lives next door, doesn’t he?”How many years did Charlie kemp and his family live next door to the wr
iter?
| A．5 years | B．10 years | C．15 years | D．20 years |

| C．Charlie Kemp treats the author as his real good friend |
| D．the author doesn't treat Charlie Kemp as his real good friend |
The author was blamed by the po
liceman because ________．

One is not born able to speak a language．One is born able to make a noise．I have heard babies cry in America and in China．I can't tell any difference．But when I hear someone from America speak English and hear someone speak Chinese, I can tell you there are a lot of differences．
I believe a common problem with Chinese students’ learning English is that they were not taught to think in English．They have an idea spoken in English and want to translate the idea into Chinese, Then they think in Chinese of the proper reply and translate it into English．After a long period of speaking the language, one begins to think in the foreign language naturally．You will learn faster if you begin to think in English at the very beginning of your study．Many students ask me: What can I do to improve my spoken English?
My reply is: The more English you speak, the better English you will speak．There are many things you can do to improve your spoken English．Of course, the best way is to live where English is spoken as a language of the country．The cries of American and Chinese babies are ________．
| A．different | B．the same | C．not like each other | D．like each other |
The underlined sentence ( in Paragraph 2 ) means that ________．
| A．some teachers didn't teach students to think in English |

| C．After speaking English for a long time, you may probably think in English naturally． |
| D．The best way of learning English is to live in America． |
Looking back on my childhood, I am quite sure that naturalists are born and not made. Although we were all brought up in the same way, my brothers and sisters soon left their pressed flowers and insects completely forever. Unlike them, I had no ear for music and
languages. I was not an early reader and I could not do mental mathematics.
Before World War I, we spent our summer holidays in Hungary. I have only the dim memory of the house we lived in, of my room and of my toys. Nor do I remember clearly the large family of grandparents, aunts, uncles and cousins who gathered next door. But I do have a clear memory of the dogs, the farm animals, the local birds, and above all, the insects
I am a naturalist, not a scientist. I have a strong love of the natural world and my interest had led me into varied investigations. I love discussing my favorite subjects and enjoy burning the midnight oil reading about other people’s discoveries. Then something happens that brings these discoveries together in my mind. Suddenly you imagine you see the answer to the question, because it all seems to fit together. This has resulted in my publishing 300 papers and books, which some might honor with the title of scientific research.
But interest, a good eye, a good memory and enjoyment of the animal and plant world do not make a scientist: one of the outstanding and necessary qualities required is self-discipline(自我修养), a quality I lack. A scientist, up to point, can be made. A naturalist is born. If you can combine the two, you get the best of both worlds.The first paragraph tells us the author __________.
| A．was interested in flowers and insects in his childhood |
| B．lost his hearing when he was a child |
| C．didn’t like his brothers and sisters |
| D．was born to a naturalist’s family |
The author can’t remember his relatives clearly because __________.
| A．he didn’t live very long with them |
| B．the family was extremely large |
| C．he was too young when he lived with them |
| D．he paid more attention to nature |
The author says that he is a naturalist rather than a scientist probably because he thinks he __________.
| A．has a great deal of trouble doing mental mathematics |
| B．lacks some of the qualities required of s scientist |
| C．just reads about other people’s discoveries |
| D．comes up with solutions in a most natural way |
