When I was fifteen, she 42 have me call people on the phone to 43 I was she. I was forced to ask for information or even to yell at people who had been rude to her. One time I had to call her stockbroker (股票经纪人). I said in an adolescent voice that was not very 44 , "This is Mrs. Tan." And my mother was standing beside me, 45 loudly, "Why he don't send me check, already two week late." And then, in perfect English I said, "I'm getting rather 46 .

By the time I had my third daughter, my middle daughter was not quite two and my oldest was three and a half. I loved them so much, yet there were some days I referred to as “too much of a good thing”.As any mother of young children knows, when the children are quiet, they’re either sleeping or in trouble. This morning, I knew that the only sleeping child at this time of day could be the baby. I was wondering whether I should enjoy the silence or ruin my peace --- and the girls’ fun.Finally, I thought I’d better go and find out what those two were doing. I could hear a noise. It was coming from the bathroom. As I got closer, I could see that the door was closed. I said to myself, “Oh no, please not the toilet again!”Sure enough, when I opened the door I saw Candace and Charity standing around the toilet, dipping their toothbrushes in --- and brushing their teeth! Not only that, but the toilet was unflushed (没冲洗的)!I hardly had any words to speak. As I snatched the toothbrushes out of their hands and flushed the toilet I shouted,“What are you doing?”Candace, my oldest daughter, answered, “We’re brushing our teeth!” They both smiled at me.Hoping this was the only time they had ever done this shocking thing, I asked, “You never did this before, did you?”Candace answered, “Oh, we do it all the time, mommy. We do it with yours and Daddy’s toothbrush, too!”The moral of the story: What you don’t know won’t hurt you; but when you do find out, it just might kill you!56. What’s the writer’s general impression of young children?A. They are polite and helpful.B. They are lovely but troublesome.C. They are clever and full of imagination.D. They are careless and make silly mistakes.57. The underlined word “moral” is closed in meaning to “_____”.A. lessonB. endingC. secretD. place58. The writer must feel worst when _____.A. she heard a noise coming from the bathroom.B. she couldn’t find her two daughters in the morning.C. she found the toilet in the bathroom had not been flushed.D. she learned her daughters had been using her toothbrush.BWhile all cultures share the same basic emotions, the body language used throughout different cultures of the world vary enormously. What can mean one thing in one country can often mean something completely different in another.For example, in North America and Europe people tend to prefer direct eye contact. But in some Asian countries longer eye contact is considered rude. So when communicating with people, always be aware of different cultural customs that may exist.A V sign in the US could mean victory, but in England, it stands for a rude challenge, which has the same meaning as showing the middle finger in the US.The OK gesture in America and England is given to mean everything is good or well. But in Latin America is looked on as a rude sign.The thumbs up sign in America and most of Europe means that something is good or well done, but it is considered rude in many Asian countries.Putting your feet on the table is generally not thought to be rude in America and England. However, in Thailand it is really rude.Telling someone to come to you by curling your index finger is acceptable in America and England, but this gesture signifies death in Singapore.Raising your hand up means stop in America and England. In some Asian countries this gesture is used when asking for permission to speak.In most westernized countries it is considered normal for two men to shake hands. In some Asian countries it is quite normal for men to kiss each other, while in most westernized countries men kissing in public would be viewed as homosexual behavior.If you would like more information on different cultural gestures all over the world, visit our website often. And we do have lots of information that interests you.59. What’s the best title for this passage?A. How gestures can vary in different cultures?B. What gestures can be acceptable in western countries?C. What can we do when traveling?D. How to be friendly to others?60. In Singapore when someone died, people there usually ________.A. put thumbs upB. curl their index fingersC. curl their middle fingersD. raise their hands up61. To what main clue is the passage written when the writer tries telling readers different cultural gestures?A. Asian countriesB. Latin AmericaC. America and EnglandD. Southern Asia62. The passage may come from ___________.A. a radio programB. a TV channelC. a magazine columnD. the InternetCShould parents ever hit their children?Research suggests many of us are likely to respond “no”, and public support for spanking(打屁股)has been fallingover the years.But surveys also show that 75 percent to nearly 90 percent of parents admit to spanking their child at least once.I was raised in a zero-tolerance home for disrespect, and my parents often turned to physical punishment.And, no, I don' t feel I was damaged by it.Nothing is more annoying than watching ill-mannered behavior from children.But there is data to suggest that a return to old-school spanking isn't the answer.Two years ago, Newsweek reported that it had found data suggesting that teens whose parents used physical punishment were more likely to become aggressive.Murray Straus, professor at the University of New Hampshire in America, has studied the topic of children and spanking for decades.He said that children who were physically punished have lower IQs than their peers.It may be that children with lower IQs were more likely to get spanked, but the punishment may have been counterproductive(反作用的)to their mental development, as well.Some researchers make the argument that occasional open-handed smacks(用巴掌打)on the bottom are not only harmless but can have some benefit.Last year, Marjorie Gunnoe, a psychologist at Calvin College, studied teens who have never spanked.There are a greater number of children growing up without ever having been physically punished.Gunnoe’s research suggests they don' t turn out any better than those who were sometimes spank.There are some parents who simply cannot control their tempers(脾气).But I still believe that the best parents are the ones who are able to offer fair and firm discipline without ever turning to physical punishment.63.According to the first three paragraphs, the author was probably hit by her parents when .A.they were dissatisfied with her grade B.she showed no respect for the elderC.they cannot control their temper D.their discipline turns out to be not strict enough 64.According to Murray Straus, children who are physically punished____ _.A.are less aggressive toward others when they get older B.have slower physical developmentC.benefit from occasional spanking D.may develop lower IQs than their peer 65.Which of the following statements is TRUE according to the article?A.40 percent of children grow up without ever being spankedB.Children who suffer less physical punishment are better studentsC.Occasional open-handed spanking on the bottom are mentally harmfulD.Researchers disagree over whether smacking is mentally harmful to children66.The author seems to agree that _ _____.A.parents should determine whether a child needs to be smacked or notB.children who have been spanked tend to behave better than those who haven'tC.good parents discipline their children in a fair and reasonable wayD.physical punishment should be the last resort(手段) of any parentDA German taxi-driver, Franz Bussman, recently found his brother who was thought to have been killed twenty years ago.While on a walking tour with his wife, he stopped to talk to a workman. After they had gone on, Mrs. Bussman said that the workman was closely like her husband and even suggested that he might be his brother. Franz laughed at the idea, pointing out that his brother had been killed in action during the war. Though Mrs. Busman knew this story quite well, she thought there was a chance in a million that she might be right.A few days later, she sent a boy to the workman to ask him if his name was Hans Bussman. Needless to say, the man’s name was Hans Bussman. And he really was Franz’s long-lost brother.When the brothers were reunited, Hans explained how it was that he was still alive.After having been wondered towards the end of the war, he had been sent to hospital and was separated from his unit(部队). The hospital had been bombed and Hans had made his way back into Western Germany on foot. Meanwhile, his unit was lost and all records of him had been destroyed. Hans returned to his home, but the house had been bombed up. Guessing that his family had all been killed during an air-raid(空袭), Hans settled down in a village fifty miles away where he had remained ever since.67. Which of the following can be used as the best title of the passage?A. Living Not FarB. Coming Back to LifeC. A Chance in a MillionD. Back after the War68. Walking along the street, _______________.k*s*5uA. Mr. Bussman recognized his brother at the first sight.B. Mr. Bussman happened to meet a workman and talked to him.C. Mrs. Bussman thought of the workman as her long-lost brother.D. Mr. and Mrs. Bussman talked to the workman for he was like his brother.69. How to understand the sentence “There was a chance in a million that she might be right.”?A. It was impossible for her to be right.B. She had no chance to meet his brother any more.C. There were many chances for her to meet his brother again.D. There was a little possibility of what she suggested, though little.70. Which of the following orders is RIGHT according to the passage?a. He walked back to Western Germany.b. He was wounded when the war was coming to the end.c. The hospital was destroyed by bombs.d. He came back to his family house.e. He was then sent to hospital.f. His unit of Germany didn’t exist any longer.A. b-a-e-d-f-cB. b-e-c-a-f-dC. b-e-a-c-d-fD. c-b-f-d-a-eEThe Nez Perce Indians are a tribe that lived in the Pacific Northwest ofthe United States. At the time of the Lewis and Clark expedition(远征队),which was one of the first journeys by Americans from the Atlantic coast tothe Pacific coast and back again, the Nez Perce territory(领土) covered about17 million acres, covering parts of Washington, Oregon, and Idaho. But thatwas a brief sweet history.In September 1805, when Lewis and Clark came off the Rockies on their westward journey, the entire exploring party was hungry and ill—too weak to defend themselves. Had the Nez Perce chosen to attack them, they could have put an end to the Lewis and Clark expedition there on the banks of Clearwater River. Instead the Nez Perce welcomed the white Americans and looked after them until theymade a full recovery.Thus began a long friendship between the Nez Perce and white Americans. But white men’s greed for land and go ld finally broke the friendship.In 1855 Governor Isaac Stevens of Washington Territory invited the Nez Perce to a peace conference. He said there were a great many white people in the country, and many more would come. But the chief of the tribe at that time, Old Joseph, replied, “Take away your paper. I will not touch it with my hand.”Things were quiet for a while after that, but not for long. When Old Joseph died, the chiefship was passed onto Young Joseph. In the late 1870s, government officials came to order the Nez Perce to leave the Wallowa Valley and then began hard battles between the Nez Perce and the white soldiers. After the tribe had fought thirteen battles and moved 1,600 miles towards Canada in an attempt to retreat (撤退) north, Young Joseph, gave in to the United States Army. Here was his famous statement, “Hear me my chiefs. I am tired; my heart is sick and sad. From where the sun now stands I will fight no more forever.”In 1885, Chief Joseph was sent along with many of his band to the Colville Reservation in Washington where Joseph continued to lead his band for another 25 years, at times coming into conflict with the leaders of 11 other tribes living on the reservation.71. What is TRUE of the Lewis and Clark expedition?A. They were well cared for by the Nez Perce.B. They ended their expedition on the banks of Clearwater River.C. They started the first battle with the Nez Perce.D. They were the first Americans to travel from the Atlantic to the Pacific.72. What ended the friendship between the Nez Perce and the Whites?A. Old Joseph’s proud manner.B. The breakdown of the peace talk.C. A growing number of white men in the land.D. W hite men’s increasing demand for land and gold.73. Young Joseph gave in at last because ________.A. he grew olderB. he was terribly illC. he hated the warD. he lost other chiefs’ support74. Which map most probably shows the path the Nez Perce took in the late 1870s?A BCD75. The passage might be followed by a paragraph about ________.A. the customs and traditions of the Nez Perce IndiansB. the last years of Chief Joseph in the Colville ReservationC. lasting fights between the Nez Perce and the whitesD. constant conflicts between the Nez Perce and other tribes第二卷(非选择题共35分)第四部分写作(共两节,满分35分)第一节短文填词(共10小题;每小题1分,满分10分)阅读下面短文,根据以下提示:1)汉语提示,2)首字母提示,3)语境提示,在每个空格内填入一个适当的英语单词,所填单词要求意义准确,拼写正确,并将该词完整地写在答题卡中相应的横线上。
