Nuclear power's danger to health, safety, and even life itself can be summed up in one word: radiation.
Nuclear radiation has a certain mystery about it, partly because it cannot be detected by human senses. It can't be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can't detect them, sense them, without a radio receiver. Similarly, we can't sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.
At very high levels, radiation can kill an animal or human being immediately by killing masses of cells in vital organs. But even the lowest levels can do serious damage. There is no levels of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and if they are killed immediately. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred. A person can be irradiated(辐射)and feel fine, then die for cancer five, ten, or twenty years later as a result. Or a child can be born weak as a result of radiation absorbed by its grandparents.
Radiation can hurt us. We must know the truth.Which of the following statements is true?
A.Nuclear radiation is just like common radio waves. |
B.Nuclear radiation can cause cancer to human beings. |
C.Nuclear radiation can be detected by human senses. |
D.Nuclear radiation can be safe to human beings if its level is low. |
How can nuclear radiation kill an animal?
A.By damaging its heart. |
B.By killing a few cells. |
C.By hitting any place in its body. |
D.By killing many cells in important organs. |
If a human being is hit by nuclear radiation, he may __________.
A.die of cancer after many years |
B.die immediately |
C.have a child who may be born weak |
D.all of the above |
Mr. Peter Johnson, aged twenty-three, battled for half an hour to escape from his trapped car yesterday when it landed upside down in three feet of water. Mr. Johnson took the only escape route—through the boot(行李箱).
Mr. Johnson’s car had finished up in a ditch(沟渠) at Romney Marsin, Kent after skidding on ice and hitting a bank. “Fortunately, the water began to come in only slowly,” Mr. Johnson said. “I couldn’t force the doors because they were jammed against the walls of the ditch and dared not open the windows because I knew water would come flooding in.”
Mr. Johnson, a sweet salesman of Sitting Home, Kent, first tried to attract the attention of other motorists by sounding the horn and hammering on the roof and boot. Then he began his struggle to escape. Later he said, “It was really a half penny that saved my life. It was the only coin I had in my pocket and I used it to unscrew the back seat to get into the boot.
It took ten minutes to unscrew the seat, and a further five minutes to clear the sweet samples from the boot. Then Mr. Johnson found a wrench and began to work on the boot lock. Fifteen minutes passed by. “It was the only chance I had. Finally it gave, but as soon as I moved the boot lid, the water and mud poured in. I forced the lid down into the mud and jumped out of the ditch.”
His hands and arms cut and bruised(擦伤), Mr. Johnson got to Beckett Farm nearby, where he was looked after by the farmer’s wife, Mrs. Lucy Bates. Huddled in a blanket, he said, “That thirty minutes seemed like hours.” Only the tips of the car wheels were visible, police said last night. The vehicle had sunk into two feet of mud at the bottom of the ditch.

All the wisdom of the ages and all the stories that have delighted mankind for centuries are easily and cheaply available to all of us within the covers of books. The most unfortunate people in the world are those who have never discovered how satisfying it is to read good books.
Reading is the pleasure of the mind, which means that it is a little like a sport: your eagerness and knowledge and quickness make you a good reader. Reading is fun, not because the writer is telling you something, but because it makes your mind work. Your own imagination works along with the author's or even goes beyond his. Your experience, compared with his, brings you to the same or different conclusions, and your ideas develop as you understand his.
Every book stands by itself, like a one--family house, but books in a library are like houses in a city. Although they are separate, together they all add up to something. They are connected with each other and with other cities. Books influence each other; they link the past, the present and the future and have their own generations, like families. Wherever you start reading, you connect yourself with one of the families or ideas, and in the long run, you not only find out about the world and the people in it but also you find out about yourself, too.
Reading can only be fun if you expect it to be. If you concentrate on books somebody tells you "you ought" to read, you probably won't have fun. But if you put down a book you don’t like and try another till you find one that means something to you, and then relax yourself with it, you will almost certainly have a good time and if you become, as a result of reading, better, wiser, kinder, or more gentle, you won't have suffered during the process.

A. listening to the author B. accepting the author's ideas
C. communicating with the author and yourself D. judging the author's work
73. The writer thinks that the most unfortunate people are those _______.
A. who don't have any books B. who can't enjoy reading books

A. show the importance of reading B. tell us how to make reading more effective

In classrooms across the USA, students from different speech backgrounds give speeches in English. It is important to remember that the major goal of the speech is communication of ideas, not perfection of language skills. Therefore, as you listen to a speaker who is not fluent in the language, seek to understand what is being said by concentrating on the ideas of the message rather than on the specific words of the speaker. This may require a special kind of patience as well as the ability to take the perspective (视角) of the communicator. Perspective taking means that you can put yourself in the other person’s shoes. That is, you try to imagine what it would be like to give a speech in a foreign language to a group of native speakers of that language. Keep in mind that non-fluency is not linked to low intelligence or lack of education~ it is linked to experiences with the second language.
These guidelines can help you be a better listener in these situations.
1. Approach the speech with a positive attitude, and expect to understand.
2. Listen all the way through. Make special efforts to keep your mind from wandering in the middle of the speech. It may help to take notes.
3. Plan to give proper nonverbal (非语言的) feedback to prove your interest, patience, and support for the speaker.
4. Control your negative emotional responses. Let's face it, it is difficult to deal with linguistic barriers (语言障碍), and people often get disappointed or bored when there are language differences.
5. Do not laugh, even if the speakers do, at their language skills. Often they laugh nervously to relieve tension.
68. What is the main idea of this passage?
A. How to become a good listener.
B. How to become a good speaker.
C. We should take a positive attitude towards speech.
D. How to communicate with others
69. The underlined phrase "put yourself in the other person’s shoes" in the first paragraph means ____.
A. to know one's shoes is to know one's problem
B. try to wear the other person’s shoes
C. understand others by trying on their shoes
D. look at something from the point of others
70. What can we learn from the passage?
A. People should be strict with speakers speaking in a foreign language.
B. Taking notes helps keep your mind from wandering in listening to a speech.
C. Whenever the speaker is nervous, he laughs.
D. It's hard to concentrate when the speaker is not fluent.
71. What advice is given on listening to a speech?
A. Believing you can understand every word of the speech.
B. Showing your support for the speaker nonverbally.
C. Laughing when the speaker laughs at himself.
D. Commenting on the speech at times.
London: What could possibly he wrong with planting trees? The benefits are obvious: they firm the soil, absorb extra water and take carbon dioxide out of the atmosphere.
However, it now turns out that planting trees could add to global warming. Tree roots do a great job of keeping soil firmly on the ground and out of the wind's power. The problem is that some of those dust clouds play an important part in taking in carbon dioxide.
Huge dust storms blow out over the oceans from dry parts of North Africa and central Asia. Tons of dust are lifted and left as a thin film over the ocean surface.
Dust from China is carried east and left in the Pacific Ocean. If a tree-planting program there is successful and the dust supply reduced, the final result may be that less carbon dioxide gets locked away in the ocean.
Andy Ridgwell, an environmental scientist from the University of East Anglia, has spent the past few years studying dust and says his work shows clearly the complexity of the system and the importance of not working uselessly with it without understanding the results. For this reason the need is to focus on cutting carbon dioxide giving off rather than dealing with the land surface aimlessly.
An American scientist, Robert Jackson, has shown that when native grassland areas are occupied by trees, carbon is lost from the soil. "We are studying why the soil carbon disappears, but one theory is that trees do a lot more of their growing above ground compared to grasses, so less carbon goes directly into the soil from trees. " said Jackson.
In wet areas of the world, the gain from trees absorbing carbon dioxide above ground seems to be outweighed by the loss of carbon from the soil below ground.
Countries that plan to combat global warming by planting trees may have to think again. Solutions to environmental problems are often more complex than they first appear, and understanding the Earth's climate is a very great challenge.
64. People usually hold the opinion that _______.
A. huge dust storms can destroy carbon dioxide
B. huge dust storms can destroy the oceans on the earth
C. planting trees could reduce global warming
D. planting trees is the only way to control huge dust storms
65. Andy Ridgwell, the environmental scientist, believes that _______.
A. environmental problems are more complex than expected
B. trees shouldn't have been planted in dry places
C. dust plays a more important part than trees
D. carbon dioxide is harmful to everything
66. Robert Jackson's experiment proves that _______.
A. carbon can turn grass into dust
B. trees hold more carbon than grass
C. less carbon can make trees grow faster
D. grassland areas should be covered by forests
67. The underlined word "combat" in the last paragraph means _______.
A. learn about B. give up C. live with D. fight against
Channel Islands
The two main islands, Jersey and Quernsey, are remarkable in that they present a combination of enjoyment, peace and quiet. Neither island is very big (only ten miles long) and so all parts of these coasts are easily reached from the main centers -- St. Helier and St. Peter Port. In both these towns and particularly in Jersey's St. Helier are the amusements of really big resorts (度假胜地). The nearness of France gives a continental atmosphere; the weather here is far better than that of any other part of England. The other three islands, Jethou, Hern and Sark are small and quiet.
Isles of Scilly
The islands are really small and quiet; the weather is warm but windy. The islands are excellent for those who enjoy exploring small inlets (水湾), creeks (小溪) and bays on foot, or better, in a boat.
Isle of Wight
he island is 24 miles across and therefore quite large. The scenery is good and varied. The resorts are neither overlarge nor showy. The island has the best sunshine record in Britain.
Isle of Man
An island with a unique atmosphere -- it is different from England, Scotland or Wales. Thirty miles long, with good roads and good public transport, the mountains, hills and deep valleys are easily reached. Douglas is a major British resort and other holiday places are lively.
60. If you want to drive to the mountains and hills, you would choose
