He always cut Mr Whi te’s hair as Mr White liked it, and while he was doing it, the two men talked about football.One day, when Mr White was sitting in his chair, and his hair was being cut as usual, the old man said to him,“ Mr White, I'm going to be sixty-five years old next month and I feel tired, so I am going to sell my shop to a young man. He likes to cut hair for people.”Mr White was very sad to hear this, because he enjoyed talking to the old man, and he was also worried that his hair would not be cut as well by the new young man as it had been for so many years by his old friend.He went to the shop again the next month, and the new young man was there. He cut Mr White's hair,but he did it badly.The next month, Mr White went into the shop again. The young man asked him how he would like his hair cut, and Mr White answered, “ Please cut it very short on the right side, but leave it as it is on the left.It must cover my ear. On top, cut all the hair away in the middle, but leave a piece at the front.”The young man was very surprised when he heard this, “But sir,” he said,“l can' t cut your hair like that.” “Why not?” Mr White asked. “That's how you cut it last time.”51.Who always cut hair for Mr White?A.

Mr White wanted the young man to know how badly he did last timeD. the young man was an old hand at cutting hairBPeople often dream of living in a perfect place where no one would be poor, no one would be rich, and everyone would be considerate of everyone else. Such a place, however, is too good to be true: such a place is nowhere, and that's what the word utopia means. It is made up of two Greek words meaning not a place.The word was first used by Sir Thomas More, a sixteenth century English writer whose book Utopia, published in 1516, described a perfect island country. More's idea for his tale came from the Greek philosopher Plato's The Republic which described what would be a perfect state.Early tales among the Norse, Celtic and Arab peoples told of a perfect place existing somewhere in the Atlantic. These tales were no longer believed after the discovery of America, but after More's time it became common for writers to imagine and describe perfect places.Today when people want certain changes in government or society, their ideas are sometimes said to be utopian. The criticism means that the changes, if effected, would not suddenly make everything perfect because people are by nature imperfect.55. Conditions in a utopian country would be such a perfect place that everyone would be ____.A. considerate of everyone elseB. happy without starvationC. equal without oppressionD. All of the above56. In modern usage, any idea said to be utopian is considered _______.A. imperfectB. unnecessaryC. impracticalD. inconsiderate57. More's Utopia was based on an _____________.A. earlier work by a philosopherB. Arab tale describing a perfect landC. imaginary tale about an island countryD. idea which came to him in a dream58. The word utopia means ________.A. two Greek wordsB. not a placeC. a perfect landD. too good to be trueCCats are creatures of habit. They like to go to sleep about the same time every day and for a certain length of time. They seem to have a natural clock inside them that tells them when to sleep. Cats increase their regular sleep with occasional cat naps(打盹). Some experts feel thathumans could also benefit from this habit. Cat naps help to build up energy in the body. They are also a good way to get rid of trouble! Since cats have the same moods (情绪) as humans, some experts believe that people can improve their moods. People might become happier.A number of famous people have copied cats by taking cat naps during the day. The naps would usually last from 15 to 30 minutes. Winston Churchill took cat naps. So did Presidents Harry Truman, John F. Kennedy, and Lyndon B. Johnson. These famous men were known for their energy. They were also able to work long hours, often into the night. Napping was their secret.59. From this selection we know that cats___________A. do not have regular sleepB. have occasional sleep as well as naps every dayC. take naps to add to their regular sleepD. take naps when they are not happy60. Taking cat naps__________A. will make a person lazy and tiredB. is a bad habitC. will make people feel betterD. can help people to become famous61.This selection was probably written to_________A. show how lazy cats areB. talk about the habits of catsC. tell about famous people and their habitsD. persuade people to take napsDScientists are trying to make the deserts into good land again. They want to bring water to the deserts, so people can live and grow food. They are learning a lot about the deserts. But more and more of the earth is becoming desert all the time. Scientists may not be able to change the desert in time.Why is more and more land becoming desert?Scientists think that people make deserts. People are doing bad things to the earth.Some places on the earth don’t get much rain. But they still don’t become deserts. This is because some green plants are growing there. Small green plants and grass are very important to dry places. Plants don’t let the sun make the earth even drier.Plants do not let the wind blow the dirt away.When a bit of rain falls,the plants hold the water. Without plants, the land can become desert more easily.62. Deserts ________________.A.never have any plants or animals in themB.can all be turned into good land before longC.are becoming smaller and smaller D.get very little rain63. Small green plants are very important to dry places because __________.A.they don’t let the sun make the earth even drierB.they don’t let the wind blow the soil awayC.they hold water D.All of the above.nd is becoming desert little by little because ___________.A.plants can’t grow there B.there is not enough rainC.people haven’t done what scientists wish them to doD.scientists know little about the deserts65.Which is the main idea of the first paragraph?A.Scientists know how to change desert into good land.B.Land is becoming desert faster than scientists can change it back into good land.C.If scientists can bring water to desert,people can live and grow food there.D.More and more places are becoming deserts all the time.66.After reading this passage,we learnt that ___________.A.plants can keep dry land from becoming desertB.it is good to get rid of the grass in the desertsC.all places without much rain will become desertsD.it is better to grow crops on dry land than to cut themEIn Canada you can find dogs, cats, horses, etc. in almost every family. These are their pets. People love these pets and have them as their good friends. Before they keep them in their houses, they take them to animal hospitals to give them injections(注射)so that they won’t carry disease. They have special animal food stores, though they can get animal food in almost every kind of store. Some people spend around two hundred Canadian dollars a month on animal food. When you visit people’s houses, they would be very glad to show you their pets and they are very proud of them. You will also find that almost every family has a bird feeder in their garden. All kinds of birds are welcomed to come and have a good meal. They are free to come and go and nobody is allowed to kill any animal in Canada. They have a law against killing wild animals. If you killed an animal,you would be punished. If an animal happened to get run over by a car, people would be very sad about it.People in Canada have many reasons to like animals. One of them might be: Their family ties are not as close as ours. When children grow up, they leave their parents and start their own life. Then the old will feel lonely. But pets can solve this problem. They can be good friends and never leave them alone.67.The passage mainly talks about _____________ .A.how to keep disease from pets B.pets in CanadaC.how to take good care of pets D.life of the old in Canada68.They give their pets injections before keeping them at their houses because _______________.A.the pets are sick B.the pets are wildC.they want to stop them from carrying diseaseD.they want them to sleep on the way home69.This passage shows that Canadians ____________ .A. hate animalsB. often kill animalsC. love animalsD. don’t keep pets inside houses 70.Which of the following is TRUE?A.People buy animal food only at the animal food stores.B.Pets eat better than people.C.Almost every family has a birdcage in his house.D.Any bird can come to the bird feeders to eat.高一年级系列化考试英语第四轮试卷第II卷(共35分)第四部分:写作(共两节,满分35分)第一节:短文改错(共10小题,每小题1分,满分10分)此题要求改正所给短文中的错误。
