1、A I have been in England for three months now. I hope you dont think Ive forgotten you. There have been so many places to see and so many things to do that Ive not had much time for writing letters.I shall soon be starting my studies at Kings College in London. So far Ive been learning about England
2、 and British ways of living. There are lots of books you can read and lots of pictures you can look at about this famous city. Im sure youll be more interested to know what I think about life hereI find some of the customs interesting. People here do not shake hands as much as we do in the mainland
3、of Europe. During the first few weeks I was often surprised because people did not put out their hands when I met them. Men raise their hats to women but not to each other21. The writer came to London _.A. for sightseeing only. B. to study.C. to learn British ways of living.D. to make a living.22. T
4、he writer came to London from _.A. Asia. B. America. C. Africa.D. the mainland of Europe. 23.

5、.BNot all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive these experiences in nightmares.Now American researchers think they are close to developing
6、a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce, or possibly wipe out, the effect of painful memories. In November, experts tested a drug on people in the US and France. The drug stops the body
7、 releasing chemicals that fix memories in the brain. So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are wiped out. They are not sure to what degree peoples memories are affected. The research has caused a great deal of argument. So
8、me think it is a bad idea, while others support it. Supporters say it could lead to pills that prevent or treat soldiers troubling memories after war. They say that there are many people who suffer from terrible memories.“Some memories can ruin peoples lives. They come back to you when you dont want
9、 to have them in a daydream or nightmare. They usually come with very painful emotions,” said Roger Pitman, a professor of psychiatry at Harvard Medical School. “This could relieve a lot of that suffering.” But those who are against the research say that maybe the pills can change peoples memories a
10、nd changing memories is very dangerous because memories give us our identity. They also help us all avoid the mistakes of the past. “All of us can think of bad events in our lives that were terrible at the time but make us who we are. Im not sure we want to wipe those memories out.” Said Rebcca Dres
11、ser, a medical ethicist.24. The passage is mainly about A. a new medical invention B. a new research on the pill C. a way of wiping out painful memories D. an argument about the research on the pill25.

12、ng bad experiences C. cause the brain to fix memoriesD. wipe out the emotional effect of memories 26. Which of the following does Rebecca Dresser agree with in the last paragraph?A. Some memories can ruin peoples lives.B. People want to get rid of bad memories.C. The pill will reduce peoples sufferi
13、ngs from bad memories.D. Experiencing bad events makes us different from others. 27. We can infer from the passage that A. the pills will certainly stop peoples emotional memories B. taking the pill will do harm to peoples physical healthC. people doubt the effect of the pills D. the pill has alread
14、y been produced and used by the public in the USCThe surprising experiment I am about to describe proves that air is all around you and that it presses down upon you. Air pressure is a powerful force. When you swim underwater, you can feel water pushing on your body. The air all around you does the
15、same. However, your body is so used to it that you do not notice this. The pressure is caused by a layer of air called the atmosphere. This layer surrounds the Earth, extending to about five kilometers above the Earths surface. The following experiment is an easy one that you can do at home. But mak
16、e sure that you are supervised, because you will need to use matches. Now for the experiment!What you needA hard-boiled egg without the shellA bottle with a neck slightly smaller than the eggA piece of paperA matchMethodCheck that the egg will sit firmly on the neck of the bottle.Tear the paper into
17、 strips and put the strips into the bottle.Light the paper by dropping a burning match into the bottle.Quickly sit the egg on the neck of the bottle.ResultAstonishingly, the egg will be sucked into the bottle. Your friends will be amazed when you show them the experiment. But be careful when you han
18、dle matches.Why it happened As the paper burns, it needs oxygen and uses up the oxygen(air) in the bottle. The egg acts as a seal in the neck of the bottle,so no more air can get inside. This reduces the air pressure inside the bottle. The air pressure must equalize, so more air from outside must en
19、ter the bottle. The outside air presses against the egg and then the egg is pushed into the bottle! This proves that air is all around and that it is pressing down on us.28. The experiment is carried out to prove .A. water pushes on your body when you swim underwaterB. the pressure of air around us
20、has a powerful force C. the earth is surrounded by a layer of air called the atmosphere D. the air pressure is not equalized around us29. Why is there the need to take care when you are doing the experiment?A. The bottle could break.B. You need to light the paper with a match.C. The egg needs to be
21、shelled.D. The egg has to be perfectly placed on the neck of the bottle.30. In the experiment, the burning inside the bottle can .A. equalize the air pressure inside and outsideB. make a seal in the neck of the bottleC. finish up the oxygen inside the bottle D. produce more oxygen inside the bottle3
22、1. How did the egg get into the bottle?A. The neck of the bottle was wide enough.B. It became soft without the shell.C. The outside air pressure forced it into the bottle.D. The oxygen inside the bottle sucked the egg in.D In America the first newspaper appeared in Boston in 1690. Published without
23、permission, it was immediately banned, and all copies were destroyed. Indeed, it remained forgotten until 1845 when the only surviving example was discovered in the British Library. The first successful newspaper was the Boston News-Letter, begun by John Campbell in 1704. Although it was heavily sup
24、ported by the government, the experiment was nearly a failure, with the limited number of published newspapers. Two more papers were published in the 1720s, in Philadelphia and New York. Just before the Revolutionary War, some two dozen papers were published in all the colonies(殖民地), although Massac
25、husetts, New York, and Pennsylvania would remain the centers of American printing for many years. Articles in colonial papers were a major force that affected public opinion in America to be fully independent.When the war ended in 1783 there were forty-three newspapers in print. The newspapers playe
26、d an active role in the affairs of the new nation. Many more newspapers were started, representing all kinds of political opinions, and Americas newspapers began to take on a central role in national affairs. Growth continued in every state. By 1814 there were 346 newspapers. The price of a years wo
27、rth of newspapers was usually over a full weeks pay for a worker. It had to be paid in full and in advance. This cheap, interesting reading material helped to make almost everyone in America develop the habit of reading, which is now taken for granted.32. The main force to affect public opinion in America for Americas independence was _.A. different kinds of newspapers B. the appearance of more papersC.the centers of American printing D. the articles in colonial ne
