The landlord(房东)also lives there, and in the past all the tenant(房客) got along fairly well with one another. Recently, however, here has been a change in their relations. A nice, quite old couple used to live there, too. The old lay would sometimes bring some small cakes she made to Jim’s mother. In return, she would give her some meat or help her with shopping. Unfortunately, the old lady died last month. Because her husband couldn’t live alone, his grandson moved in.The grandson, a young man of about twenty, has become a problem to Jim’s family because he is so is so noisy. Jim’s family members were uses to peace and quietness, but the young man likes listening to music late at night. Sometimes his friends come for a visit, and they also make a lot of noise. Everyone in Jim’s family has been troubled by the new comer.Jim’s mother once politely asked the old man if he was ablr to sleep well at night, but it seemed that he didn’t understand what she meant and so never spoke to his grandson about it. If he did, the grandson obviously didn’t listen, since things have not changed any. Everyone in Jim’s family agrees that something has to be done, but no one wants to hurt the old man’s feeling or cause him any problems.( ) 41. Which of the following statements is not true?A. The old man could not live without his wife’s help.B. It is hard for the old couple to do shopping all by themselves.C. Jim’s mother was kind to her neighbor.D. Jim’s mother was the only one in the family who lied their neighbor’s grandson.( )42. The grandson makes a lot of noise because____.A. he never cares whether the neighbor might want to live in peace and quietnessB. the doors are always openC. he likes listening to music early in the morningD. he needs to practise singing all day long( )43 In the underlined sentence of the second paragraph, “everyone in Jim’s family has been troubled by the new comer”, here “troubled” means _______.A. felt sorryB. interruptedC. felt excitedD. hated( )44. Jim’s mother once politely asked the old whether he could sleep well at night, because_____.A. she worried about the old man’s healthB. she wanted to remain the old man to speak to his grandson about the noiseC. she didn’t want the old man to make noise at nightD. she wasn’t troubled by the noise at all( )45. So far, _____ will be able to solve the problem caused by the new comerA. only Jim’s motherB. only the old manC. nobodyD. only the grandson’s friendsBIf you do not use your arms or your legs for some time, they become weak; when you start using them again, they slowly become strong again,. Everybody knows this, and nobody would think of questioning this fact. Yet there are many people who do not seem to know that the memory works in the same way. When someone says that he has a good memory, he really means that he keeps his memory in practice by exercising it regularly, either consciously(有意识地)or unconsciously. When someone else says that his memory is poor, he really means that he does not give it enough opportunity to become strong. The position is exactly the same as that of two people, one of whom exercises his arms and legs by playing tennis, while the other sits in a chair or motor car all day.If a friend complains that his arms are weak, we know that it is his own fault. But if he tells us that he has a poor memory , many of us think that his parents are to blame(责备), or that he is just unlucky. Few of us realize that it is just the same as his arms or legs are weak. Not all of us can become specially strong or specially clever, but all of us can improve our health and our memory by the same way ---practice.Have you ever noticed that people who cannot read or write usually have better memories than those who can? Why is this? Of course, because those who cannot read or write have to remember things, because they cannot write them down in a little notebook. They have to remember everything by heart, so their memory is being exercised all the time. So if you want to have a good memory, keep practicing remembering.( )46. Which of the following is TRUE, according to the first paragraph?A. Everybody knows that memory works in the same way as the arms or legs do.B. It is a fact that some people never use their arms or legs.C. To have a good memory , one has to exercise it regularly.D. To keep fit, one should never sit in a chair or a motor car.( ) 47. According to this text, poor memory results from________.A. bad habitsB. poor healthC. poor educationD. lack of remembering practice( ) 48. The writer of this passage seems to advise us to ______A. blame ourselves rather than our parents for the poor memoryB. blame our parents rather than ourselves for the poor memoryC. complain about nothing but ourhealthD. play tennis to improve our memory( )49. The writer of this passage comes to the conclusion that _______.A. the poorer he is, the better memory he hasB. memory can be improved by practicing itC. the poor people may help you remember thingsD. if you want a good memory, do not read or write anything( )50. Which of the following may best serve as the title of this passage?A. How to Improve Your MemoryB. Your Arms, Legs and BrainC. People with Weak Arms and LegsD. Poor and Good Memory( )51. According to the advertisement, these three books are for________A. soldiersB. farmersC. childrenD. workers( )52.

When I was in her home, I heard what I ‘ve heard all my life. "I love you, mom They would 45 this to each other at least five times a day-when mom got Grandma up, made her comfortable in bed, or prepared her 46.And I would hear love’s 47 when Grandma said,” And I love you too.”Love forgives and 48,not focusing on what has happened.

On that day we send our mothers a special Mother's Day card, and perhaps some flowers or candy, to show our love and appreciation for all they have done for us. Although Mother's Day is a relatively new holiday in America, more and more other countries are also setting aside a day to honor their mothers.It all started over a hundred years ago with a woman named Anna May Jarvis. Anna was born on May 10,1864, just before the end of the Civil War and the assassination of President Lincoln. She was the daughter of a“minister”, which in American English means a church leader. She was a quiet girl who liked to study in school, but she liked everyone and was liked by everyone as well.After she graduated, Anna worked for life insurance company in Philadelphia, Then, in 1906, her mother died. It was the second Sunday in May.In the months that followed, Anna began to change. No longer was she so gentle, so relaxed and easy-going. Instead she now had just one goal for her life--to have her mother and all other honored throughout the whole world on the second Sunday of May.After more than a year of careful planning, Anna arranged the first Mother's Day church service, on May10, 1908, in Crafton, West Virginia. The next year Anna was able to get the city of Philadelphia, where she lived and worked, to proclaim the second Sunday of May as an official Mother's Day -- the first city to do so. After three more years, the state of West Virginia, where Anna's mother had lived, made Mother's Day a statewide observance--for a holiday in the normal sense, but still a day to remember what mothers have done for their children and society.51.Which answer is right about Mother's Day?A. In America, Mother's Day is a new holiday.B. More and more countries are put aside their tradition of celebrating Mother's Day.C. In America, Mother's Day is on the second Sunday in May.D.

Anna was born just before the assassination of President Lincoln which ended the Civil War.B. Anna was a daughter of a minister which in English means a church worker.C. Anna's mother's death had done a little damage to her easy life.D. The mother's day celebrated in West Virginia is a day with special meaning.55. What most probably happened in the following paragraph ?A. Mother's Day is celebrated in conventional celebration.B. Mother's Day gradually became a commercial celebration.C. Anna retired from her job with a fortune of over a hundred thousand dollars.D. People stopped buying candy to their mothers.BOne day a few years ago, a very funny thing happened to a neighbor of mine. He is a teacher at one of London's big medical schools. He had finished his teaching for the summer term and was at the airport on his way to Russia to give a lecture.He had put a few clothes and his lecture notes in his shoulder bag, and he had put Rupert, the skeleton (人体骨架) to be used in his lecture, in a large brown suitcase.

不知是神灵的佑护还是大自然的疏忽,在荒漠的皱褶里,有时会不可思议地生存着一片红柳丛。

它们有着铁一样锈红的枝干,凤羽般纷披的碎叶,偶尔会开出穗样细密的花,对着高原的酷寒和缺氧微笑。

这高原的精灵,是离太远最近的绿树,百年才能长成小小的一蓬。
