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 clonc 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 peoplearound 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 reb pepole 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.Futhermore,cloning would make the uniqueness that each one of us possesses disapparance.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 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.

70.Which of the following shows the structure of the passage
It feels like every time my mother and I start to have a conversation, it turns into an argument. We talk about something as simple as dinner plans and suddenly, my mother will push the conversation into World War. She’ll talk about my lack of a bright future because I don’t plan to be a doctor. And much to her disappointment, I don’t want to do any job related to science, either. In fact, when I was pushed to say that I planned to major(主修) in English and communications, she nearly had a heart attack.“Why can’t you be like my co-worker’s son?” she bemoans all the time. Her co-worker’s son received a four-year scholarship and is now earning 70,000 dollars a year as an engineer. I don’t know what to answer except that I simply can’t be like Mr. Perfect as I’ve called the unnamed co-worker’s son. I can’t be like him. I’m the type of person who loves to help out in the community, write until the sun goes down, and most of all, wants to achieve a career because I love it, not because of fame (名声) or salary.
I understand why my mother is worried about my future major. I’ve seen my mother struggle to raise me on her small salary and work long hours. She leaves the house around 6:30 am and usually comes home around 5 pm or even 6 pm. However, I want her to know that by becoming a doctor, it doesn’t mean I’ll be successful. I’d rather follow my dreams and create my own future.Which of the following topics do the writer and his mother often talk about?

Knowing the best way to study will help you to be a better student. By using your time properly, you can do your homework more quickly. Learning to study is not difficult.
The first thing to remember is that you must be willing to learn. It doesn’t mean that you must always like the subject. It does mean, however, that you must be wil1ing to do whatever is necessary to learn. Try to understand why it is important and how it will help you now and later to do and learn other things. Knowing mathematics facts will be useful in your whole life. Knowing how to spell makes any kind of writing easier. Sometimes subject that you think is going to be uninteresting will be exciting when you begin to work at it and understand it more clearly. Learning things can be fun if you are willing to work with them.
Here’s some advice for you: have a certain time each day and a quiet place with good lighting for study, so that you can concentrate on your study without interruptions(中断); have everything ready before you sit down to study, a dictionary, paper, a pen and books; be sure you understand what you should learn before you start; read carefully and pay special attention to the most important things; when memorizing, first find out the main parts and then recite the whole thing; check your homework after you finish it; never forget the importance of review and preview.The main purpose of the article is______
| A．to prove that learning is not difficult |
| B．to make the readers be interested in study |
| C．to tell the importance of self teaching |
| D．to tell the students how to study well |
We learn things because______
| A．our parents want us to learn |
| B．every student learns at school |
| C．we may use these things in the future |
| D．we like the subjects |
Which of the following is NOT the advice given in the article?

Then comes July, and with it examinations, but these are soon finished and with them ends the school year. Boys and girls have nearly two months’ holiday before them as they leave school by train and car to return home to their fathers and mothers.
The summer holidays are the best part of the year for most children. The weather is usually good, so that one can spend most of one’s time playing in the garden or, if one lives in the country, out in the woods and fields. Even if one lives in a big town, one can usually go to a park to play.
The best place for a summer holiday, however, is the seaside. Some children are lucky enough to live near the sea, but for the others who do not, a week or two at one of the big seaside towns is something that they will talk about for the whole of the following year.
In England, it is not only the rich who can take their children to the seaside; if a factory worker or a bus driver, a street cleaner or a waiter wants to take his wife and children to Southend or Margate, Blackpoor or Clacton, he is usually quite able to do so.
Now, what is it that children like so much about the seaside? I think it is the sand, sea and sun more than any other things. Of course, there are lots of new things to see, nice things to eat, and exciting things to do, but it is the feeling of sand under one’s feet, of salt water on one’s skin, and of the warm sun on one’s back that make the seaside what it is.After the examination, pupils leave for home________
| A．by train only |
| B．by air |
| C．by bike |
| D．by either train or car |
July and August are the brightest months for most children, for they can_____.
| A．stay with their parents for all the vacation. |
| B．do more reading |
| C．play out-of-door |
| D．meet their old friends |
Children like the seaside so much, because they can ______.
| A．swim in the sea |
| B．play with the sand |
| C．take a sun bath |
| D．do all of the above |
Miss Gogers taught physics in a New York school. Last month she explained to one of her classes about sound, and she decided to test them to see how successful she had been in her explanation. She said to them, “Now I have a brother in Los Angeles. If I was calling him on the phone and at the same time you were 75 feet away, listening to me from across the street, which of you would hear what I said earlier, my brother or you and for what reason?”
Tom at once answered, “Your brother. Because electricity travels faster than sound waves.” “That's every good,” Miss Gogers answered; but then one of the girls raised her hand, and Miss Gogers said. “Yes, Kate.”
“I disagree,” Kate said. “Your brother would hear you earlier because when it's 11 o'clock here it's only 8 o'clock in Los Angeles.”Miss Gogers was teaching her class_________.

You don’t know what you’ve got until it’s gone. I’ve learned that through my personal experiences. A few months ago, I woke up deaf in one ear. I did not pay much attention to it at first. It felt that I had water in my ear. However, I began to hear less and less out of that ear. I even had to ask people to talk into my other ear so that I could hear them. I didn’t realize how serious it was until late in the day (为时太晚). One evening, when I was sitting on my bed doing chemistry homework, I fell off my bed. When trying to get up, I was incredibly dizzy (头晕的).
I went to see a doctor and he told me that hearing loss was common. However, hearing loss is usually bilateral, or occurs in both ears. He said that my hearing should come back within a week. After about a week the dizziness eventually went away, but the hearing loss did not. The medicine helped and I gained some of my hearing back. After many hearing tests, the doctor diagnosed (诊断) that I had permanent hearing loss in that ear.
School became harder for me because I couldn’t hear my teachers. I was very depressed. Finally, I bought a hearing aid. With the hearing aid, my hearing is almost back to normal. It makes school and group conversations easier.
My friends, teachers and even complete strangers always ask me questions about hearing loss. I answer them patiently. I never get offended because I know this is new to them. I am delighted that I can teach them something new.
What I have learned from this particular situation is that when things are desperate（绝望的；急切的）, there is always something good that can come out of it. My experiences have given me an opportunity to teach people about hearing loss and also taught me about the value of hearing.What happened to the author?
