It was my mother’s idea. She wanted me to “make something” of myself, and decided I had better start young if I was to have any chance of keeping up with the competition. With my load of magazines I headed toward Belleville Avenue. The crowds were there. There were two gas stations on the corner of Belleville and Union. For several hours I made myself highly visible, making sure everyone could see me and the heavy black letters on the bag that said THE SATURDAY EVENING POST. When it was supper time, I walked back home. “How many did you sell, my boy?” my mother asked. “None.” “Where did you go?” “The corner of Belleville and Union Avenues.” “What did you do?” “Stood on the corner waiting for somebody to buy a Saturday Evening Post.” “You just stood there?” “Didn’t sell a single one.” “My God, Russell!” Uncle Allen put in, “Well, I’ve decided to take the Post.” I handed him a copy and he paid me a nickle(五分镍币). It was the first nickle I earned. Afterwards my mother taught me how to be a salesman. I would have to ring doorbells, address adults with self-confidence, and persuade them by saying that no one, no matter how poor,
could afford to be without the Saturday Evening Post in the home. One day, I told my mother I’d changed my mind. I didn’t want to make a success in the magazine business. “If you think you can chang e your mind like this,” she replied, “you’ll become a good-for-nothing.” She insisted that, as soon as school was over, I should start ringing doorbells, selling magazines. Whenever I said no, she would scold me. My mother and I had fought this battle almost as long as I could remember. My mother, dissatisfied with my father’s plain workman’s life, determined that I would not grow up like him and his people. But never did she expect that, forty years later, such a successful journalist as me would go back t o her husband’s people for true life and love. 56．Why did the boy start his job young? A．He wanted to be famous in the future B．The job was quite easy for him. C．His mother had high hopes for him. D．The competition for the job was fierce. 57．From the dialogue between the boy and his mother, we learn that the mother was _______. A．excited B．interested C．ashamed D．disappointed 58．What did the mother do when the boy wanted to give up? A．She forced him to continue. B．She punished him. C．She gave him some money. D．She changed her plan. 59．The phrase “this battle”in the last paragraph refers to . A．the war between the boy’s parents B．the arguing between the boy and his mother C．the quarrel between the boy and his customers D．the fight between the boy and his father 60．What is the text mainly about? A．The early life of a journalist. B．The early success of a journalist. C．The happy childhood of the writer. D．The important role of the writer in his family. B Researchers have found more evidence that suggests a relationship between races and rates(率) of lung cancer among smokers. A new study shows that black people and Native Hawaiians are more likely to
develop lung cancer from smoking. It compared their risk to whites, Japanese-Americans and Latinos. Researchers at the University of Southern California and the University of Hawaii did the new study. The New England Journal of Medicine published the findings. The eight-year research studied more than 180,000 people. They included present and former smokers and people who never smoked. Almost 2.000 people in the study developed lung cancer. Researchers say genetics(遗传学) might help explain the racial and ethnic（种族的） differences. There could be differences in how people's bodies react to smoke. But environmental influences, including the way people smoke, could also make a difference. African-Americans and Latinos in the study are reported smoking the fewest cigarettes per day. Whites are the heaviest smokers. But the scientists point out that blacks have been reported to breathe cigarette smoke more deeply than white smokers. This could fill their lungs with more of the chemicals in tobacco that cause cancer. Scientists know that some diseases effect different groups differently. And some drug companies have begun to develop racially targeted(针对) medicines. Last June, the United States Food and Drug Administration approved a drug designed to treat heart failure in black patients. The name is BiDil. The agency called it "a step toward the promise of personalized medicine." 61．Which of the following orders is from higher to lower risk of having lung cancer? A．Whites―Native Hawaiians
B．Africans―Americans―Latinos C．Asians―Native Hawaiians D．Africans―Americans―Native Hawaiians 62．Researchers agree that it is that may probably deter mine black people’s risk of lung cancer. A．the larger amount of smoking than white people B．the living style or habit of the blacks C．the depth of cigarette smoke into their lungs D．the physical strength to
react to cigarette smoke 63．People in the new study are made up of . A．heavy smokers in America B．the black and white people C．the Asians and Hawaiians D．smokers and non-smokers 64．The production of BiDil referred to in the last paragraph is to . A．explain different races react to some diseases differently B．tell the readers that racial differences exist in smokers C．show a big step people have taken in the medicine area D．support the idea that it is easy for blacks to have cancers 65．Which of the following statements is TRUE according to the author? A．The way of smoking may increase the risk of lung cancer. B．Race has nothing to do with the risk of having a lung cancer. C．The research was started by the New England Journal of Medicine. D．The risk of lung cancer lies I how much a person smokes. C "The world's oceans are slowly getting more acidic．”say scientists．The researchers from California report that the change is taking place in response to higher levels of carbon dioxide in the atmosphere. The lowering of the waters’pH value is not great at the momen t but could cause a serious threat to current ocean life if it continues, they warn. Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature. Increasing use of oil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater. Once in the water, it reacts to form carbonic acid. Scientists believe that the oceans have already become slightly more acidic over the last century. These researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change．"This level of acidity will get much more extreme in the future if we continue releasing COZ into the atmosphere," said Dr Caldeira. "And we predict the amount of
future acidity will exceed（超过）anything we have seen over the last several hundred million years, let alone perhaps after rare disastrous events such as asteroid（小1j-%+.'_) impacts．” However, it is not absolutely clear what that means for ocean life．Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean life forms may be more sensitive to pH changes．Coral reefs and other organisms whose shells contain calcium carbonate（小行星) may be particularly affected if the water's acidity levels keep going up, the team predict. They could find it much more difficult to build these structures in water with a lower pH. In recent years some people have suggested storing carbon dioxide from power stations in the deep ocean as a way of dealing with global warming．But Dr Caldeira said that such a strategy should now be re-considered. "Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing 一because in releasing CO2 into the atmosphere we warm the planet, and when CO2, is absorbed by the ocean, it reduces the amount of greenhouse warming.” 66 ．The ocean is becoming more acidic due to＿． A，the lower water pH value B．the warming atmosphere C ．the higher level of COZ in the air D．the increasing use of oil fuels 67． According to Dr Caldeira,＿． A ．ocean absorption of carbon dioxide is a good thing B ．more oil fuels will be used in the near future C ．scientists may predict climate changes with computer models D ．the future situation of the amount of acidity is extremely serious 68．If the water's acidity level keeps rising,＿． A ．ocean life whose structures contain calcium carbonate may be affected B ．the waters’pH value will become higher and hig her C ．organisms living near the surface are more sensitive to pH changes D ．some disastrous events will occur more often than before 69．Most
experts once believed storing carbon dioxide in the ocean would reduce＿． A ．the COZ absorbed by the ocean B ．the amount of greenhouse warming C ．the acidity of the ocean D ．the gradul release Of CO2 70．The purpose of this passage is to＿． A ．show people the findings of a research team B ．inform people of how acid the ocean is now C ．introduce Dr Caldeira and his team's research D ．warn people of the higher level of COZ D As you move around your home, take a good look at the things you have. It is likely that your living room will have a television set and a video, and your kitchen a washing machine and a microwave oven. Your bedroom drawers will be filled with almost three times as many clothes as you need. You almost certainly own a car and possibly a home computer, holiday abroad at least once a year and eat out at least once a week. Now, perhaps, more than ever before, people are wondering what life is all about, and what it is for. Seeking material success is beginning to trouble large numbers of people around the world. They feel that the long hours work culture to make more money is eating up their lives, leaving them very little time or energy for family or pastimes. Many are turning to other ways of living and downshifting is one of them. Six percent of workers in Britain took the decision to downshift last year. One couple who downshifted is Daniel and Liz. They used to work in central London. He was a newspaper reporter and she used to work for an international bank. They would go to work by train every day from their large house in the suburbs, leaving their two children with a nanny. Most evenings Daniel wouldn’t get home until eight or nine o’clock and nearly twice a month he would have to fly to New York for meetings. They both earned a large amount of money but began to feel that life was passing them by. Nowadays, they run a farm in the mountains of Wales.
“I always wanted to have a farm then,” says Daniel, “and we took almost a year to make the decision to downshift. It’s taken some getting used to, but it’s been worth it. We have to think twice now about spending money on car repairs and we no longer have any holidays. However, I think it’s made us stronger as a family, and the children are a lot happier. Liz, however, is not quite sure. “I used to enjoy my job, even though it was hard work and long hours. I’m not really a country girl, but I suppose I’m gradually getting used to looking after the animals. One thing I do like, though, is being able to see more of my children. My advice for other people wanting to do the same is not to think about it too much or you might not do it at all.” 71．The passage tells us that . A．people seldom work long hours to make money B．people hardly buy more things than necessary C．people are sure everything they own is in the right place D．people realize there is more to life than just making money 72．When Daniel was a reporter he ___. A．lived in central London B．disliked his job C．missed his children D．was well paid 73．Daniel and Liz both agree that the move to the farm ____. A．was easy to organize B．has improved family life C．was extremely expensive D．has been a total success 74．What does the author mean by saying“the long hours work culture to make more money is eating up their lives” in the second paragraph ? A．People work long hours to earn their living. B．To make more money through hard work is the aim of people’s life. C．Long hours of hard work occupy too much of people’s life. D．People spent too much time and money eating meals. 75．The underlined word “downshifting” in the second paragraph refers to _________. A．repairing your car by yourself B．spending money carefully C．moving out to the countryside to live a simpler and better life D．living
in a big house in the suburbs and dining out once a week 第Ⅱ卷（共45分）新课标第一网第四部分书面表达（共两节，满分45分）第一节阅读表达（共5小题；每小题3分，满分15分）阅读下面的短文，并根据短文后的要求答题（请注意问题后的字数要求）。 Maybe you are an average student. You probably think you will never be a top student. This is not necessary so, however. Anyone can become a better student if he or she wants to. Here’s how. Plan your time carefully. When you plan your week, you should make a list of things that you have to do. After , you should make a schedule of your time. First arrange your time for eating, sleeping, dressing, etc. Then decide a good, regular time for studying. Don’t forget to set aside enough time for entertainment. A weekly schedule may not solve all the problems, but it will force you to realize what is happening to your time. Find a good place to study. Look around the house for a good study area. Keep this space, which may be a desk or simply a corner of your room, free of everything but study materials. No games, radios or TV! When you sit down to study, concentrate on the subject. Make good use of your time in class. Take advantage of class time to listen to everything the teacher says. Really listening in class means less work later. Taking class notes will help you remember what the teacher says. Study regularly. When you get home from school, go over your notes. Review the important points that your teacher has mentioned in class. If you know what your teacher is going to discuss the next day, read the material. This will help you understand the next class. If you do these things regularly, the material will become more meaningful, and you will remember it longer. Develop a good attitude towards the tests. The purpose of a test is to show what you have learned about a subject. They help you to remember your new knowledge. The world won’t end if you
don’t pass a test, so don’t be overly worried. There are other methods that might help you with your studying. You will probably discover many others after you have tried these. 76．What is the best title of the passage? (Please answer within 10 words.) 77．Which sentence in the passage can be replaced by the following one? Never let tests trouble you in your study. 78．Please fill in the blank in the third paragraph with proper words or phrases to complete the sentence.(Please answer within 10 words.) 79．Which suggestion do you think is the best for you ? Why?(Please answer within 30 words.) 80．Translate the underlined sentence in the fifth paragraph into Chinese. 第二节写作（满分30分）教育部倡导学生：每天锻炼一小时；健康工作五十年；幸福生活一辈子请你根据以上提示，用英语准备一份发言稿，向同学们讲述一下阳光体育活动的有关情况，并就高中学生是否需要每天花一小时锻炼，谈谈你的看法及理由。注意： 1．发言稿应包括以上所有信息，要有适当发挥。 2．词数：120左右。 3．参考词汇：阳光体育活动-a national student sports program；教育部-the Ministry of Education

Eleven million students in Shandong took an active part in this program. The ministry of Education calls on students to exercise for an hour every day, in the hope that
they will have good health to work fifty years and enjoy the whole life. Personally, I think it a good idea for us senior students to have daily exercise. Although we take an hour a day for exercise, it is well worth it. Taking exercise helps us build up our body and keep a clear mind. Therefore we can work more efficiently. Thank you!

(1) No, you don’t need to take out a pencil and paper; you can do this in your head, especially if whatever you are reading is a news article or a dense report. Simply read the first two paragraphs of the text to get an overview of its main points and, from there, jump down each paragraph reading only the first sentence. These are the brain exercises that help you get smarter. Use a pointer We know using your finger to read can make you feel like you’ve traveled backward to the second grade, but it’s one of the easiest ways to increase speed. (2) Aim to move the pointer faster and faster with each line. You’ll be forced to group words together in order to keep up. Stop repeating

人教版数学必修四模块综合测试题 (满分150分，时间120分钟) 一、选择题(本大题共12小题，每小题5分，共60分.在每个小题给出的四个选项中，只有一项是符合题目要求的) 1.下列叙述中正确的是( ) A.三角形的内角必是第一象限或第二象限的角 B.角α的终边在x 轴上时，角α的正弦线、正切线分别变成一个点 C.终边相同的角必相等 D.终边在第二象限的角是钝角 思路解析：由正弦线、正切线的定义可知B 正确,A 中漏了直角的情况，直角终边在y 轴上，不属于第一象限也不属于第二象限. 答案：B 2.若α、β的终边关于y 对称，则下列等式正确的是( ) A.sinα=sinβ B.cosα=cosβ C.tanα=tanβ D.cotα=cotβ 思路解析：因为α、β的终边关于y 对称，所以β=2kπ+π-α,k ∈Z ，sinβ=sin(2kπ+π-α)=sinα.或者通过定义sinα=r y ,也可判断. 答案：A 3.函数y=2sin2xcos2x 是( ) A.周期为2π的奇函数 B.周期为2π 的偶函数 C.周期为4π的奇函数 D.周期为4 π 的偶函数 思路解析：y= 22sin4x,T=42π=2π,又f （-x ）=22sin （-4x ）=-2 2 sin4x=-f （x ），它是奇 函数. 答案：A 4.已知向量a =(3,2)，b =(x,4),且a ∥b ，则x 的值为( ) A.6 B.-6 C.38- D.3 8 思路解析：因为a ∥b ，所以3×4-2x=0，解得x=6. 答案：A 5.下面给出四种说法，其中正确的个数是( ) ①对于实数m 和向量a 、b ，恒有m(a-b)=ma-mb ；②对于实数m 、n 和向量a ，恒有(m-n)a=ma-na ；③若ma=mb(m ∈R)，则a=b ；④若ma=na(a≠0)，则m=n. A.1 B.2 C.3 D.4 思路解析：正确的命题有①②④，③当且仅当m≠0时成立. 答案：C 6.已知|a|=1,|b|=2,a 与b 的夹角为60°，c=2a+3b,d=k a -b (k ∈R )，且c ⊥d ，那么k 的值为( ) A.-6 B.6 C.5 14- D.514 思路解析：a·b=1×2×cos60°=1.∵c ⊥d,
