For each of them there are four choices marked A, B, C and D. You should decide on the best choice.Passage 1When we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.People who are near-sighted can only see things that are very close to their eyes, Everything else seems blurry(=unclear). Many people who do a lot of work, such as writing, reading and sewing become near-sighted. Then people who are far-sighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm’s length. If they want to do much reading ,they must get glasses, too.Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people’s eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle (角度). To prove this to yourself, look at an object our of one eye; then look at the same object out of your other eye. You will find the object’s relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an1. We should take good care of our eyes C . .A. only when we can see wellB. only when we cannot see perfectlyC. even if we can see wellD. only when we realize how important our eyes are2. When things far away seem indistinct(模糊不清) , one is probably A . .A. near-sightedB. far-sightedC. astigmatic3. The underlined word suffer in the second paragraph probably means D . .A. experienceB. imagineC. feel pain4. Having two eyes instead of one is particularly useful for D . .A. seeing at nightB. seeing objects far awayC. looking over a wide area5. People who suffer from astigmatism have B . .A. one eye bigger than the otherB. eyes that are not exactly the right shapeC. a difficulty that can be corrected by an operationD. an eye difficulty that cannot be corrected by glassesPassage 2In earliest times, men considered lightning to be one of the great mysteries (神秘的事物) of nature. Some ancient peoples believed that lightning and thunder were the weapons (武器) of the gods.In reality, lightning is a flow of electricity formed high above the earth. A single flash of lightning 1.6 kilometres long has enough electricity to light one million light bulbs (灯泡).The American scientist and statesman, Benjamin Franklin, was the first to show the connection between electricity and lightning in 1752. In the same year he also built the first lightning rod (避雷针). This device (装置物) protects buildings from being damaged by lightning.Modern science has discovered that one stroke (闪击) of lightning has a voltage (电压) of more than 15 million volts (伏特). A flash of lightning between a cloud and the earth may be as long as 13 kilometers, and travel at a speed of 30 million meters per second.Scientists judge that there are about 2,000 million flashes of lightning per year. Lightning hits the Empire State Building in New York City 30 to 48 times a year. In the United States alone it kills an average (平均数) of one person every day.The safest place to be in case of an electrical storm is in a closed car. Outside, one should go to low ground and not get under tress. Also, one should stay out of water and away from metal fences. Inside a house, people should avoid open doorways and windows and not touch wires or metal things.With lightning, it is better to be safe than sorry?1. People once thought lightning came from __B______.A. the skyB. the godsC. the earthD. nature2. According to the passage what do you think all buildings need?CA. Metal fences.B. Electricity.C. lightning rods.D. Machines.3. Lightning can travel _D__.A. as quickly as waterB. not so quickly as electricityC. at very low speedD. at very high speed4. Which of the following is NOT true?CA. In the U.S about one person per day dies from lightning.B. The Empire State Building frequently gets hit by lightning.C. Swimming during a thunder storm is a good idea.D. A closed car is the best place to be during an electrical storm.5. Lightning is probably ___A___ to man.A. usefulB. kindC. uselessD. friendlyPassage 3Grandma Moses is among the most famous twentieth-century painters of the United States, yet she did not start painting until she was in her late seventies. As she once said of herself：“I would never sit back in a rocking chair, waiting for someone to help me.” No one could have had a more productive old age.She was born Anna Mary Robertson on a farm in New York State, one of five boys and five girls. At twelve she left home and was in domestic(家庭的) service until, at twenty-seven, she married Thomas Moses, the hired hand of one of her employers. They farmed most of their lives, first in Virginia and then in New York State, at Eagle Bridge. She had ten children , of whom five survived ; her husband died in 1927. Grandma Moses painted a little as a child and made embroidery(刺绣) pictures as a hobby, but onlychanged to oils in old age because her hands had become too stiff(硬的) to sew and she wanted to keep busy and pass the time. Her pictures were first sold at the local drugstore(杂货店) and at a market and were soon noticed by a businessman who bought everything she painted . Three of the pictures exhibited in the Museum of Modern Art, and in 1940 she had her first exhibition in New York. Between the 1930’s and her death she produced some 2,000 pictures: detailed(详细的)and lively portrayals(描绘) of the country life she had known for so long, with a wonderful sense of colour and form. “I think really hard till I think of something really pretty, and then I paint it.” she said.1.

Grandma Moses spent most of her life D .A. nursingB. paintingC. embroideringD. farming3. The underlined word survived means C .A. graduated from collegeB. examined the condition of the houseC. lived longer than the other childrenD. gave up themselves to the police4.

Which of the following would be the best title for the passage? AA. Grandma Moses: Her Life and Pictures.B. The Children of Grandma Moses.C. Grandma Moses: Her Best Exhibition.D. Grandma Moses and Other Older Artists.Passage 4It must have been around nine O’clock when I drove back home from work because it was already dark. As I came near to the gates I turned off the headlamps of the car so as to prevent the beam(光荣) from swinging(摇摆)in through the window and waking Jack, who shared the house with me. But needn’t have done so, I noticed that his light was still on, so he was awake anyway—unless he had fallen asleep while reading. I put the car away and went up the steps, Then I opened the door quietly and went to Jack’s room. He was in bed awake but he didn’t even turn towards me.“What’s up, Jack?” I said.“For God’s sake(看在上帝面上), don’t make a noise,” he said.The way he spoke reminded me of someone in pain who is afraid to talk in case he does himself a serious injury(伤害).“Take your shoes off, Neville,” Jack said.I thought that he must be ill and that I had better humour (迁就)him to keep him happy, “There’s a snake here” he explained, “It’s asleep between the sheets. I was lying on my back reading when I saw it. I knew that moving was out of the question. I couldn’t have moved even if I’d wanted to .” I realized that he was serious. “I was relying on you to call a doctor as soon as you came home.” Jack went on.“It hasn’t。
