1.已知 Sn 是等差数列an 的前 n 项和,若 a4 = 3 ,则 S7 = __________.
【详解】当 x 0 时, −x 0 ,由已知得 f (−x) = cos(−x) = cosx ,
因为 f ( x) 是 R 上的奇函数,所以 (f x)= − (f − x)= −cosx .
故答案为 f ( x) = −cosx ( x 0) .
【点睛】本题主要考查函数的奇偶性,解决本题的关键在于:当 x 0 时,求出 f (−x) ,再寻求 f ( x) 与
f (−x) 的关系.

Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)One of the most inspiring quotes(名言) I ever heard was by Brian Tracy. He said: “The differences between successful people and unsuccessful people is that successful people fail many more times than unsuccessful people.”I deeply understood the wisdom of the quote soon after my fist book was published.I was living in Atlanta at the time and arranged my first signing sale for my new book at the phoenix and Dragon, the largest bookstore in the city. Although a nice sign was placed outside the room exhibiting images of both me and my book, not a single customer entered the room.Do they not like the title? I wondered. Do they not like the book cover? After 90 minutes, I was absolutely distraught.For the four years writing the book, I had felt a sense of mission and purpose like never before in my life. Working a full 8-hour day in my clinic, I had to get into bed by 9:30 pm every day, so I could wake up at 5:30 in the morning and have two hours of writing before heading into my clinic. Before I ever began each writing session, I would close my eyes for 10 minutes and then whisper, ”Please grant me the words to touch just one person’s life.”Now, sitting there alone at my first book signing, I wondered if my entire life wasn’t just a big joke. At that moment, just when I couldn’t feel any worse, a middle-aged couple walked into the room. I managed to hide my emotions and introduced myself and my book. The couple turned the pages each other, and the husband nodded to his wife. She then told me, “I think we’ll get the book.” Despite the impulse (冲动)to jump in the air, and hold their hands to thank them for being my first readers, I realized the woman was trying to say something else.“The reason we’re buying it,” she said hesitantly, “is because our son committed suicide two years ago. Maybe your story will help us get over it.”At that moment, I knew if I never sold another copy of the book, my four years of writing it had served its purpose. Although I would have many more challenging years until my book became a bestseller, this couple’s story was all the motivation I needed at that point to keep me ahead. Thanks to them, I would realize that thegreatest of lives are made all in the same way: One challenge ... one challenge ... one difficulty ... one step ... and one small victory at a time.56. The writer quotes Brian Tracy to emphasize the important of _________________.A. successB. confidenceC. braveryD. perseverance57. The word “distraught” probably means ______________.A. bored and impatientB. cheerful and proudC. upset and disappointedD. miserable and ashamed58. What can be inferred from paragraph 4?A. The writer had to quit his job to make time for his writing.B. The writer was not sure about the purpose of his writing at first.C. The writing was completed with great self-discipline and efforts.D. The process of writing the book was full of pains and happiness.59. By saying “my four years of writing it had served its purpose”. The author probably means that _____________.A. he had succeeded in selling his first book to the coupleB. he had managed to touch someone’s life with his bookC. he was quite satisfied with the feedback of his readersD. he had found someone who enjoyed his writing(B)60.Which of the following is the most suitable for Mary,who can just spare one day to travel around Singapore?A.City Sightseeing.B.DUCK.C.Night safari.D.Flyer.61.If David and his 9-year-old son are both animal lovers,they had better dial __________ for more information before their tour.A.6338-6859B.6338-6826C.6338-3311D.6338-6877 62.Mr. Smith is going to take his wife,his 13-year-old daughter and his 1-year-old son John to visit Singapore at their own leisurely pace, so he should get at least ________ ready.A.﹩89.B.﹩99.C.﹩91.D.﹩101.(C)Labor force is defined as being the total number of people who are available to work and earn income. This definition includes everyone who is employed or seeking paid employment,so it includes employers and the self-employed.Labor is one of the country’s resources which can be combined with other resources to produce the goods and services wanted by the community.Although the size of the workforce depends a great deal on the size of the total population,there are several other influences which also affect it.The age distribution (分布) of the total population has a very marked effect on the available workforce. If the population has a high proportion of very young people or of those too old to work,then the available workforce would be lower than if there were an balanced spread age distribution.If the population naturally grows rapidly, the number of births greatly exceeds (超出) the number of deaths then as a total population increases proportion of the workforce declines.Sometimes a population is described as aging which means that the birth rate is either falling or growing very slowly,and as people retire from the workforce there are insufficient numbers of young people entering it to replace those who are leaving it.In that situation the population is top-heavy with older people.So the percentage of the population in the workforce declines when there is either a rapidincrease in births or a falling birth rate.The age distribution of the population has several important effects on the economy.If the population is aging and there is an increase in the number of people retiring without a corresponding increase in the number entering the workforce,this raises the problem of the ability of the economy to provide a reasonable level of social services to the retired group.If the aged are to be cared for in special homes,finance must be available for that purpose.If the size of the workforce is small relative to the total population,then the government tax revenue(税收) is relatively low and either the government has less money available to it or the workforce members have to be taxed more heavily.63.In the passage “labor force” is defined as ___________.A.people who are available to work and earn incomeB.self-employed people onlyC.people who are looking for an employmentD.employers who create job opportunities64.The conclusion which can be drawn from the second paragraph is that___________.A.a natural growth of population leads to a balanced workforceB.a large population does not necessarily mean a higher proportion of workforce C.the larger the population,the higher the proportion of the workforce D.the workforce will be lower, if the population has a balanced age distribution,65.When a population is said to be aging,___________.A.there are more people retiring than those entering the workforceB.the birth rate must be growingC.there should be an oversupply of workforceD.There are more people entering the workforce than those retiring66.The population which is top-heavy with older people ___________ of a country.A.leads to the high rate of unemploymentB.results in low tax on the workforce membersC.affects employees’ incomesD.places pressure on the economy(D)Directions: Complete the following passage by using the sentences given below. Each sentence can be used only once. Note that there are two more sentences than you need.Conflict happens. It happens everywhere: between friends, in the classroom, around the corporate conference table. The good news is that it doesn't have to damage friendships or business deals. Knowing how to resolve conflict, wherever it happens, creates confidence and eases stress.Be prepared for any conditionsCare enough about your own well-being, your relationships with co-workers and your company, to talk about what is bothering you at work, to talk about conflict.Don't take it home or stuff it away. Ignoring something doesn’t make it go away.Start preparing to resolve a conflict by checking your own behavior. (67) ___________ Have they been pushed? How have you handled the situation so far? What is your own responsibility in the matter?(68) ___________The sooner you resolve conflict, the easier it is to resolve. Don't hang around.Don't let the matter boil into something bigger than it is.If a specific behavior has caused the conflict, promptness gives you an exampleto refer to and keeps you from building up hostility. It also gives the other person the best chance of understanding the specific behavior you want to talk about. Find a private, neutral placeTalking about conflict has almost no chance of succeeding if it’s carried out in public. Nobody likes to be embarrassed in front of peers or made an example of in public. Your goal is to eliminate the tension created by conflict. Privacy will help you. (69) ___________Share your feelingsNine times out of 10, the real conflict is about feelings, not facts. (70) ___________ Owning your own feelings, and caring about others', is key to talking about conflict. Remember that anger is a secondary emotion. It almost always arises from fear.IV. Summary WritingDirections: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.According to an official report on youth violence, “In our country today, the greatest threat to the lives of children and adolescents is not disease or starvation or abandonment, but the terrible reality of violence”. Given that his is the case, why aren’t students taught to manage conflicts the way they are taught to solve math problems, drive cars, or stay physically fit?First of all, students need to realize that conflicts are unavoidable. It is reported that most violent incidents between students begin with a relatively minor insult. For example, a flight could start over the fact that one student eats a peanut butter sandwich each lunchtime. Laughter over the sandwich can lead to insults, which in turn can lead to violence.If the conflict occurs, students can practice the golden rule of conflict resolution: stay calm. Once the student feels calmer, he or she should choose words that will calm the other person down as well. Rude words and accusations only addfuel to the emotional fire while soft words can put out the fire before it explodes out of control.After that, they can use another key strategy for conflict resolution: listening. Listening allows the two sides to understand each other. One person should describe his or her side, and the other person should listen without interrupting. Afterwards, the listener can ask non-threatening questions to clarify the speaker’s position. Then the two people should change roles.Finally, students need to consider what they are hearing. An argument doesn’t mean trying to figure out the fault of the other person but means understanding what the real issue is. As the issue becomes clearer, the conflict often simply becomes smaller.第 II 卷 (共40分)I. Translation(3+3+4+5)Directions: Translate the following sentences into English, using the words given in the brackets.71.让观众失望的是这位著名音乐家表现得如此粗鲁。
