山东省淄博市六中2021-2022学年高二上学期第17周周末自主学习材料英语试题 Word版含答案
2022级高二英语自主学习材料文理通用第17周命题人：冯祚新任教班级：25班审核人：隽丕东任教班级： 7、8班姓名：班级：第一部分：阅读理解（共2节，满分70分）第一节(共30小题;每小题2分，满分60分)AProfessor Martin’s report says that children who attend a number of different schools, because their parents have to move around the country, probably make slow progress in their studies. There are also signs, says Professor Martin, that an unusually large number of such children are mentally affected.The Profes sor says, “It’s true, my personal feeling is that children should stay in one school. However, our findings are based on research and not on any personal feelings that I or my assistants may have on the subject.”Captain Thomas James, an Army lecturer for the past 20 years and himself a father of 2 children, said, “I’ve never heard such rubbish. Taking me for example, no harm is done to the education of my children who change school regularly---if they keep to the same system. In my experience----and I’ve known quite a few of them---- Army children are as well-adjusted(调整) as any others, if not more so. What the professor doesn’t appear to notice is the fact that in such situations children will adapt much better than grown-ups.”When this was put to Professor Martin, he said that at no time had his team suggested that all such children were mentally affected in some way, but simply that in their experience there was a clear tendency (倾向). “Our finding shows that while the very bright child can deal with regular change without harming his or her general progress in studies, the majority of children suffer from constantly having to enter a new learning situation.”1. Professor Martin’s report suggests that _______.A. it may not be good for children to change schools oftenB. parents should not move oftenC. more and more children are mentally affectedD. children will make rapid progress if they stay in one school.2. According to the passage, Professor Martin’s personal feeling____ .A. is the opposite of what his report has shownB. is in a way supported by his researchC. has played a big part in his researchD. is based on his own experience as a child3. From the passage, we can conclude that Captain Thomas’ children____.A. have been affected by changing schoolsB. have not been affected by changing schoolsC. like every army school they have been inD. are the brightest among the children who often change school4. According to Professor Martin, ____ suffer from changing schools regularly.A. non-army childrenB. bright childrenC. the majority of childrenD. few children5. Captain Thomas believes _____A. army children are generally better—adjusted than any othersB. army children are usually less experienced than any othersC. children can adapt more easily and quickly than grown-upsD. children can adapt as easily and quickly as grown-upsBDuring the 20th century there has been a great change in the lives of women. A woman marrying at the end of the 19th century probably have been in her middle 20’s and would be likely to have seven or eight children. By the time the youngest was 15, the mot her would have been in her early 50’s and would expect to live a further 20 years, during which chance and health made it hard for her to get paid work. Today women marry younger and have fewer children.Usually a woman’s youngest child will be 15 when sh e is 45 and she can be expected to live another 35years and is likely to get paid work until 60.This important change in women’s life has only recently begun to have its full effect on women’s economic position. Even a few years ago most girls left school and took a fulltime job. However, when they married they usually left work at once and never returned to it. Today the school-leaving age is 16, many girls stay at school after that age, and though women marry younger, more married women stay at work at least until shortly before their first child is born. Very many more return to work later. Such changes have led to a new relationship in marriage, with the husband accepting a greater share of the duties of family life.6. We learn from this passage that in the 19th century_____ .A. there were more children in the world than there are todayB. women spent a greater part of their lives raising children than they do todayC. there were more women in poor health than there are todayD. women married younger than they do today7. One reason why a married woman of today may take a job is that ____.A. she is usually younger when her children are old enough to look after themselvesB. she is obliged to help her husband support the familyC. she feels lonely at home when her children grow upD. she hopes to change the world a bit by doing up8. Many girls are now likely to ____.A. give up their jobs after they get marriedB. leave school as soon as they canC. marry early so that they can get better jobsD. continue working until they are going to have a baby9. According to the passage, it is now quite usual for women to ____ .A. stay at home after leaving schoolB. find jobs when they reach the age of 16C. start working again later in lifeD. marry and have children while still at school10. Now a husband probably ____ .A. plays a greater part in looking after the childrenB. does almost all of the houseworkC. feels unhappy about his wife’s going out to workD. takes a part-time job so as to help at homeCIn 1896, Einstein went to Zurich to study physics. There he met a girl from Hungary. They studied in the same class and the same interest in physics brought them together and they became good friends. Before long they fell in love. In 1903 when Einstein was 24, he married Marits, who was 4 years older than he.After their marriage, Einstein devoted himself to the research of the great theory. To give her husband more help, Marits gave up her own work, and became a good wife and assistant. She tried her best to encourage him whenever possible. She was sure that her husband would succeed. They often discussed the theory while walking outside or sitting together in the room. They even did that in their letters when one of them was away from their home.In1914, Einstein moved to Berlin and settled down there. At that time his theory proved to be correct and he had become famous all over the world. But it was not long before the First Would War broke out. Marits as well as her two sons, who was on holiday in Switzerland, couldn’t come back to Berlin any more. The war not only stopped Einstein’s work but also broke up the warm, happy family. In 1919, Einstein and Marits had to get divorced(离婚).11. Form this passage we can see that Marits was born in _____.A.1896B. 1879C. 1883D.187512. We can learn from the passage that Marits ______.A. greatly helped Einstein with his research workB. supported Einstein but helped him littleC. was also a great scientistD. was the real discoverer of the theory13. The last paragraph mainly tells us _____.A. why Einstein and Marits got divorcedB. why Einstein moved to BerlinC. how Einstein became famous all over the worldD. when the First World War broke out14. Why did Einstein and Marits get divorced?A. Because Marits didn’t love Einstein after the war broke out.B. Because the war stopped Marits from coming back to Berlin.C. Because Einstein only cared about his research.D. Because Einstein was famous all over the world.15. The writer wanted to tell us that _____.A. Marits should be respected as greatly as her husbandB. Einstein suffered a great deal in his lifeC. The bitter (苦难的) suffering was the mother of successD. We should remember Marits when talking about Einstein’ theoryDAfter giving a talk at a high school, I was asked to pay a visit to a special student. An illness had kept the boy home, but he had expressed an interest in meeting me, and it would mean a great deal to him. I agreed.During the nine-mile drive to his home, I found out something about Matthew. He had muscular dystrophy（肌肉萎缩症）. When he was born, the doctor told his parents that he would not live to see five, and then they were told he would not make it to ten. Now he was thirteen. He wanted to meet me because I was a gold-medal power lifter, and I knew about overcoming obstacles (障碍) and going for my dreams.I spent over an hour talking to Matthew. Never once did he complain or ask, “Why me?” He spoke about winning and succeeding and going for his dreams. Obviously, he knew what he was talking about. He didn’t mention that his classmates had made fun of him because he was different. He just talked about his hopes for the future, and how one day he wanted to lift weight with me.When we finished talking, I went to my briefcase and pulled out the first gold medal I won and put it around his neck. I told him he was more of a winner and knew more about success and overcoming obstacles than I ever would. He looked at it for a moment, then took it off and handed it back to me. He said, “You are a champion. You earned that medal. Someday when I get to the Olympics and win my own medal, I will show it to you.”Last summer I received a letter from Matthew’s parents telling me that Matthew had passed away. They wanted me to have a letter he had written to me a few days before:Dear Rick,My mom said I should send you a thank-you letter for the picture you sent me. I also want to let you know that th e doctors tell me that I don’t have long to live anymore. But I still smile as much as I can. I told you someday I was going to the Olympics and win a gold medal. But I know now I will never get to do that. But I know I’m a champion, and God knows that too. When I get to Heaven, God will give me my medal and when you get there, I will show it to you. Thank you for loving me.Your friend,Mathew16. The boy wanted to meet the author because ______.A. he was interested in what the author was doingB. he wanted to get a gold medal himselfC. he admired the author very muchD. he wanted the author to know him too17. The underlined part in the third paragraph probably means “______”.A. Why do you come to see me?B. Why do I have to stay at home?C. Why does the disease fall on me?D. Why not give a gold medal to me?18. We can infer from the passage that ______.A. Matthew was a determined boy and considered himself as normalB. Rick used to have the same disease and later became a power lifterC. Matthew was to become a champion before he diedD. After meeting Matthew, Rick regarded him as normal19. The boy refused the author’s medal because ______.A. he wanted the picture insteadB. he would not be pitied by othersC. he did not know he would die soonD. he himself could earn one in the future20. The author wrote the passage with the purpose of ______.A. describing his unusual friendship with a disabled childB. showing his admiration towards the disabled childC. telling an experience of meeting a disabled childD. expressing his pity to all the disabled childrenENo one knows why we sleep, but it's certain that we need to. People who are prevented from sleeping begin to suffer obvious effects after a few days--they think less clearly, and they fall asleep during the working hours; some may have hallucinations(幻觉).There are no rules about sleep. Generally speaking, grown-ups sleep about 7 and a half hours each night and probably more than 60 percent get between seven and eight hours. But perhaps eight per cent are quite happy with 5 hours or less, and 4 per cent or so find that they want ten hours or more. If you feel all right, you're probably getting enough sleep. The important thing is not to worry how much other people get.Their needs may be different. Exercise doesn't seem to increase the need for sleep--office workers, for example, sleep for about as long as people doing physically active work.Children sleep more than grown-ups--perhaps 14 to 18 hours soon after birth, going down to grown-up levels by early teen-age. Sleep patterns also tend(倾向) to be different in the elderly, who may sleepless at night than they did when younger, find sleep getting more broken, and often make it a rule to sleep during the daytime.21. According to the passage, some people are unable to think clearly because ________.A. they have hallucinationsB. they feel sleepy during the working hoursC. they don't have enough sleepD. they are certain to be kept from going to bed22. Which of the following is true?A. All grown-ups must have at least eight-hour sleep.B. Most of grown-ups sleep for seven or eight hours.C. Quite a few people need only 5 hours or less for them to sleep.D. No grown-ups sleep more than ten hours.23. Whether you have got enough sleep is judged by ________.A. how many hours you have sleptB. how many hours you need to sleepC. whether you do exercise and physical workD. whether you feel fresh and energetic24. According to the passage, a boy of 14 years old sleeps ________.A. as long hours as a grown-upB. much longer hours than a grown-upC. for 14 hours each nightD. for less than 8 hours per night25. Who finds they sleep less during the night and must take a nap during the day?A. ChildrenB. Grown-upsC. Young peopleD. Old peopleFBill Javis took over our village news-agency at a time of life when most of us only want to relax. He just thought he would like something but not too much to do, and the news-agency was ready-made. The business produced little enough for him, but Bill was a man who only wanted the simplicity and order and regularity of the job. He had been a long-serving sailor, and all his life had done everything by the clock.Every day he opened his shop at six a. m. to catch the early trade; the papers arrived on his door-step before that. Many of Bill’s customers were city workers, and the shop was convenient for the station. Business was tailing off by 10 o’clock, so at eleven sharp Bill closed for lunch. It was hard luck on anybody who wanted a paper or magazine in the afternoon, for most likely Bill would be down on the river bank, fishing, and his nearest competitor was five kilometers away. Sometime in the afternoon, the evening paper landed on the doormat, and at 4 o’clock Bill reopened. The evening rush lasted t ill seven, and it was worthwhile.He lived in a flat above the shop, alone. Except in the very bad weather, you always knew where to find him in the afternoon, as I have said. Once, on a sunny afternoon, I walked home along the river bank from a shopping trip to the village. By my watch it was three minutes past four, so I was astonished to see Bill sitting there on his little chair with a line in the water. He had had no luck, I could see, but he was making no effort to move.“What’s wrong, Bill?” I call ed out from the path.For answer, he put a hand in his jacket and took out a big, golden object. For a moment I had no idea what it could be, and then it suddenly went off with a noise like a fire engine. Stopping the bell, Bill held the thing up and call ed back, “Ten to four, you see, and this is dead right.”I had never known anyone carrying a brass alarm clock round with him before.26. Bill Javis became a news-agent when ______.A. he needed the moneyB. he decided to take things easyC. he was quite an old manD. he gave up clock-repairing27. Bill opened the shop so early in the day because ______.A. he liked to do as much as possible before he went to workB. the shop had to be open when the morning papers cameC. he was never sure of the timeD. it was then that he did a lot of business28. You might say “Hard luck” to someone who ______.A. has just heard some very good newsB. is less fortunate than he or she ought to beC. puts great effort into whatever he or she triesD. fails through his or her own fault entirely29. On that sunny afternoon, the writer was surprised when he saw Bill because ______.A. he thought it was late for Bill to be still fishingB. he thought Bill was ill, since he was not moving at allC. Bill had not caught anything, and that seemed strangeD. Bill stayed in his flat30. From the information given in the passage, who or what do you think was wrong?A. The bell was; it must have gone off at the wrong time.B. Bill was; he had dropped off to sleep.C. The writer’s watch was fast.D. Bill’s clock was wrong; it was very old.其次节(共5小题;每小题2分，满分10分)依据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
