"We've had to make a difficult decision, " Mr. Tisich announced. "You see, your mother has been offered a post as co-director of a television station in Chicago Unfortunately, the station is not here. After thinking long and hard about it, we've concluded that the right decision is to move to Chicago." Marc looked shocked, while his sister Rachel breathlessly started asking when they'd be moving. "It's surprising, but exciting!" She said. Marc simply said, "We can't go—I can't leave all my friends. I'd rather stay here and live with Tommy Lyons!" The Tisichs hoped that by the time they moved in August, Marc would grow more accustomed to the idea of leaving. However, he showed no signs of accepting the news, refusing to pack his belongings.When the morning of the move arrived, Marc was nowhere to be found. His parents called Tommy Lyons's house, but Mrs. Lyons said she hadn't seen Marc. Mrs. Tisich became increasingly concerned, while her husband felt angry with their son for behaving so irresponsibly.What they didn't know was that Marc had started walking over to Tommy's house, with a faint idea of hiding in the Lyons's attic(阁楼)for a few days. But something happened on the way as Marc walked past all the familiar landscape of the neighborhood: the fence that he and his mother painted, the tree that he and his sister used to climb, the park where he and his father often took evening walks together. How much would these mean without his family, who make them special in the first place? Marc didn't take the time to answer that question but instead hurried back to his house, wondering if there were any moving cartons(纸板箱)the right size to hold his record collection.(1) The conflict in this story was caused by.A. Marc and Rachel's different tempersB. a quarrel between Tommy Lyons and MarcC. Marc's disagreement with his parents about their moveD. Mr. and Mrs. Tisich's remark of Marc's irresponsibility(2) Marc and Rachel's reactions to the move were similar in the way that bothwere.A. surprisedB. angry and upsetC. anxious for more detailsD. worried about packing(3) The reason for Marc's going home was that.A. he did not want to be left behindB. he realized his family was essential to himC. he hoped to reach an agreement with his parentsD. he wished to be a more responsible person(4) What would most likely happen next?A. Marc would bring his records over to the Lyons's house.B. Mr. and Mrs. Tisich would call the police.C. Marc would join his family for house moving.D.

Mr. John Evans had never found the time or the money—to make the trip from his home near Swansea. But, when British Rail offered him an all-expenses-paid birthday trip to the capital, he just could not refuse.Until yesterday he had never been far from home, except for one trip to Aberdeen. Mr. Evans, who spent 60 years working as a miner in South Wales, almost made the journey to London once before, at the turn of the century. "There was a trip to the White City but it was ten shillings(1 shilling=1/20 pound )return from Swansea—too much I thought. All my money went to the family then, " he said.During the next two days Mr. Evans will be taken on a whistle—stop tour of London to see the sights. Top of his list is a visit to the Houses of Parliament(国会).The only arrangement he does not care for is the wheelchair provided to move him about if he gets tired. "I don't like the chair business—people will so think I am getting old, "he said.His secret for a long and healthy life has been well publicized—no alcohol, no cigarette and no anger. Before setting off from Swansea with his 76-year-old son. Amwel, he quipped, "I'm glad to see they've given me a return ticket."(1) It was reported that Mr. Evans's healthy long life was to a certain extent due tohis.A. wine drinkingB. proper smokingC. mild temperD. sense of humor(2) Which of the following statements is true?A.

We don't stop, we keep our faces expressionless and eyes straight ahead, and in doing so, we are not just protecting ourselves but are avoiding overloading other people as well.We make use of stereotypes(刻板的模式)as convenient ways to make quick judgments about situations and people around us. They may not always be accurate, and they can often be dangerously wrong, but they are used regularly.The problem with the stereotypes is that they restrict experience. By using limited close to provide us with a rapid opinion of other people or places we may choose to limit our communication. We may decide not to go to certain places because we believe they will not offer something we enjoy.In the city, styles of dress are particularly important with regard to self-presentation. Different group often use clearly identifiable styles of clothes so that they can be easily recognized. It is becoming increasingly common for brand names to be placed on the outside of clothes, and this labeling makes it easy to send out information about fashion and price instantly, and lets others tell at a distance whether an individual has similar tastes and is a suitable person to associate with.In England, where social grouping or class continues to make social distinctions(区分), clothes, hairstyles, people's pronunciation and the manner of speaking are all clues to our social group. Class distinctions tend to be relatively fixed, although in the city where greater variety is permitted, they are more likely to be secondary determining factors of friendship and association.(1) People walking in cities ignore the surroundings because.A. they do not wish to talk to other peopleB. everyone else is expressionlessC. the environment is already familiar to themD. there is too much information to take in(2) According to the passage, the main disadvantage of using stereotypes is thatthey.A. are likely to lead us into dangerous situationsB. may make us miss some pleasant experienceC. can rarely be relied onD. make us mentally lazy(3) From the passage we may conclude that.A. stereotypes can help to understand people fullyB. people are becoming more interested in fashionC. dressing can send messages about individualsD. stereotypes can do more harm than good to people(4) It would appear that in England, a person's class.A. might be less important in making friends in a cityB. is mainly determined by his pronunciationC. plays less of a role than it did in the pastD. is something that can be changed easily四、翻译句子(每题3分,满分15分)37、【来源】 2001年高考真题上海卷第86题3分翻译我们的祖国从来没有像今天这样强大。

here.After thinking long and hard about it,we’ve concluded that the right decision is to move to Chicago.”Marc looked shocked,while his sister Rachel breathlessly started asking when they’d be moving.“It’s surprising,but exciting!”she said. Marc simply said,“We can’t go — I can’t leave all my friends. I’d rather stay here and live with Tommy Lyons!”The Tisichs hoped that by the time they moved in August,Marc would grow more accustomed to the idea of leaving.However,he showed no signs of accepting the news,refusing to pack his belongings.When the morning of the move arrived,Marc was nowhere to be found.His parents called Tommy Lyons’s house,but Mrs. Lyons said she hadn’t seen Marc. Mrs. Tisich became increasingly concerned, while her husband felt angry with their son for behaving so irresponsibly.What they didn’t know was that Marc had started walking over to Tommy’s house,with a faint idea of hiding in the Lyons’s attic(阁楼)for a few days.But something happened on the way as Marc walked past all the familiar landscape of the neighborhood:the fence that he and his mother painted,the tree that he and his sister used to climb,the park where he and his father often took evening walks together.How much would these mean without his family,who make them special in the first place?Marc didn’t take the time to answer that question but instead hurried back to his house, wondering if there were any moving cartons(纸板箱)the right size to hold his record collection.71.The conflict in this story was caused by______.A.Marc and Rachel’s different tempersB.a quarrel between Tommy Lyons and Marc中鸿智业信息技术有限公司C.Marc’s disagreement with his parents about their moveD.Mr. and Mrs. Tisich’s remark of Marc’s irresponsibility72.Marc and Rachel’s reactions to the move were similar in the way that both were______.A.surprisedB.angry and upsetC.anxious for more detailsD.worried about packing73.The reason for Marc’s going home was that_______.A.he did not want to be left behindB.he realized his family was essential to himC.he hoped to reach an agreement with his parentsD.he wished to be a more responsible person74.What would most likely happen next?A.Marc would bring his records over to the Lyons’s house.B.Mr. and Mrs. Tisich would call the police.C.Marc would join his family for house moving.D.Mr. and Mrs. Tisich would start searching for Marc.2、(6分)Answer the following questions by using the information taken from a dictionary page.(You may read the questions first.)中鸿智业信息技术有限公司jaguar n. a type of large, yellow-colored cat with black markings found in the southwestern region of the U.S. and in Central and South America.jargon 1 n. speech that doesn’t make sense. 2 n. an unknown language that seems strange or impossible to understand. 3 n. a language made up of two or more other languages:His jargon was a mixture of French and English. 4 n. the special vocabulary of a field or profession:Her report on computers was filled with jargon.jaunt 1 n. a trip taken for fun. 2 v. to go on a brief pleasant trip:We jaunted to the country last Saturday.javelin 1 n. a spear most commonly used as a weapon or in hunting.2 n. a light-weight metal or wooden spear that is thrown in track-and-field contests. 3 n. the contest in which a javelin is thrown. 4 v. to strike, as with a javelin.jazz 1 n. a type of music that originated in New Orleans and is characterized by rhythmic beats. 2 n. popular dance music influenced by jazz. 3 n. slang empty talk.4 adj. of or like jazz:a jazz band, jazz records.jennet n. a small Spanish horse.75.Which meaning of the word javelin is used in the sentence below?At the competition,Jack drew his arm back and threw the javelin 50 yards.A.Definition 1B.Definition 2C.Definition 3D.Definition 476.Which meaning of the word jargon is used in the sentence below?Doctors often speak in medical jargon.中鸿智业信息技术有限公司 或 A.Definition 1B.Definition 2C.Definition 3D.Definition 477.What does the word jazz mean in the following sentence?Don’t give me that jazz,for I am a practical person.A.rhythmic beatsB.a type of musicC.a kind of danceD.meaningless talk3、(8分)Britain’s oldest man made his first visit to London yesterday at the age of 110. Mr. John Evans had never found the time or the money — to make the trip from his home near Swansea.But,when British Rail offered him an all-expenses-paid birthday trip to the capital,he just could not refuse.Until yesterday he had never been far from home,except for one trip to Aberdeen. Mr. Evans,who spent 60 years working as a miner in South Wales,almost made the journey to London once before,at the trun of the century.“There was a trip to the White City but it was ten shillings(1 shilling=1/20 pound)return from Swansea — too much I thought.All my money went to the family then,”he said.During the next two days Mr. Evans will be taken on a whistle-stop tour of London to see the sights.Top of his list is a visit to the Houses of Parliament(国会).The only arrangement he does not care for is the wheelchair provided to move him about if he gets tired.“I don’t like the chair business — people will so think I am getting old,”he said.中鸿智业信息技术有限公司 或His secret for a long and healthy life has been well publicized — no alcohol,no cigarette and no anger. Before setting off from Swansea with his 76-year-old son, Amwel, he quipped,“I’m glad to see they’ve given me a return ticket.”78.It was reported that Mr. Evans’s healthy long life was to a certain extent due to his______.A.wine drinkingB.proper smokingd temperD.sense of humor79.Which of the following statements is true?A.A single trip from Mr. Evans’s home to the White City used to be ten shillings.B.The first place for Mr. Evans to visit is the Houses of Parliament.C.He appreciated people’s arrangement of a wheelchair during his visit.D.Mr. Evans once made the journey to London at the turn of the century.80.The word“quip”in the last sentence most probably means______.A.to make a witty remarkB.to express a happy messageC.to make a wishD.to tell a joke81.What might be the best title for this passage?A.110-Year-Old TouristB.Secret for Long and Healthy Life中鸿智业信息技术有限公司 或 C.Free Return TicketD.Sightseeing in London4、(8分)When we walk through the city , we all experience a kind of information overload but we pay attention only to those that are important to us. We don’t stop , we keep our faces expressionless and eyes straight ahead , and in doing so, we are not just protecting ourselves but are avoiding overloading other people as well.We make use of stereotypes(刻板的模式)as convenient ways to make quick judgements about situations and people around us.They may not always be accurate,and they can often be dangerously wrong,but they are used regularly.The problem with the stereotypes is that they restrict experience.By using limited clues to provide us with a rapid opinion of other people or places we may choose to limit our communication.We may decide not to go to certain places because we believe they will not offer something we enjoy.In the city,styles of dress are particularly important with regard to self-presentation.Different groups often use clearly identifiable styles of clothes so that they can be easily recognized.It is becoming increasingly common for brand names to be placed on the outside of clothes,and this labeling makes it easy to send out information about fashion and price instantly,and lets others tell at a distance whether an individual has similar tastes and is a suitable person to associate with.In England,where social grouping or class continues to make social distinctions(区分),clothes, hairstyles, people’s pronunciation and the manner of speaking are all clues to our social group. Class distinctions tend to be relatively fixed,although in the city where greater variety is permitted,they are more likely to be secondary determining factors of friendship and association.82.People walking in cities ignore the surroundings because______.A.they do not wish to talk to other peopleB.everyone else is expressionless中鸿智业信息技术有限公司C.the environment is already familiar to themD.there is too much information to take in83.According to the passage, the main disadvantage of using stereotypes is that they______.A.are likely to lead us into dangerous situationsB.may make us miss some pleasant experienceC.can rarely be relied onD.make us mentally lazy84.From the passage we may conclude that______.A.stereotypes can help to understand people fullyB.people are becoming more interested in fashionC.dressing can send messages about individualsD.stereotypes can do more harm than good to people85.It would appear that in England,a person’s class______.A.might be less important in making friends in a cityB.is mainly determined by his pronunciationC.plays less of a role than it did in the pastD.is something that can be changed easily四、书面表达 ( 本大题共 1 题, 共计 15 分)1、(15分)Write an English composition in over 120 words,according to the topic given in Chinese.中鸿智业信息技术有限公司请你谈谈轿车大量进入家庭后,对家庭、环境和经济可能产生的影响。

本题的复杂度为 O(A(N,5)*5^3*3^2)
第三题 三国围棋赛
【题目大意】
给出中国队N个人,从中选出5个,和韩国队5人,日本队5人 进行比赛,我们已经知道了两两之间的胜率,中国队作为东 道主,可以在对方选手安排好出场顺序后再决定队员的组成 以及出场顺序,以得到最大的获胜概率。 比赛规则如下:先抽签决定第1轮轮空的队,由不轮空的2支 队的1号队员进行比赛,失利的队员被淘汰,以后每次由前 一轮获胜的队员与前一轮轮空的队剩下的队员中序号最小的 队员进行比赛,直到只剩下一个国家的队员为止,这个国家 就获得了比赛的胜利。求中国队获胜的概率
分析
关于转移
要根据l和o的情况分别来考虑
分析 初始化
A[I,j] 表示中国队i和韩国队j的胜率 B[I,j]表示中国队i和日本队j的胜率 c[I,j] 表示日本队i和韩国队j的胜率 f[5,5,4,2,1]:= c[1,1]/3; f[5,4,5,3,1]:= (1-c[1,1])/3; f[5,5,4,1,2]:= b[g[1],1]/3; f[4,5,5,3,2]:= (1-b[g[1],1])/3; f[5,4,5,1,3]:= a[g[1],1]/3; f[4,5,5,2,3]:= (1-a[g[1],1])/3;
分析
可以通过递归求解。 即num3,num7,num9,我们有发现这些数 的乘积的最后一个数字会形成长度为4的循环 节。 然后再把多余的没有与5形成0的2乘回去。
如何求解num3,num7,num9
递归求解 X div 10+ 抽出2和5那部分剩下来的数
计算num3,num7和num9
计算num3,num7和num9
分析
N个人中选5个,显然需要枚举。
于是我们先从N个中找出5个人,来计算最优 解。
分析
现在问题转化成已知三个国家的15位参赛人员 和出赛安排,计算中国队的胜率
显然算概率,可以搜,当然也可以用DP
分析
F[I,j,k,l,o] 上一轮o队轮空,赢的队伍是l,三个国家剩下 的人数为i,j,k的局面的概率
算法实现
以上可以通过记忆化搜索的形式实现 Ans=f[0][0][0][0]
第二题
【题目大意】 求N!最后一位非0位的数字 N<=10^100
分析
计算0的个数很简单,我们只要计算N!中2 的因子有多少个就行了。因为5的因子一定比2 的因子要少。 这个我们可以通过递归来求解。
分析
那么我们可以得到2的因子有num2个 5的因子有num个。 抽调2和5的因子后,剩余数字的个位上的数字 只可能有4种1,3,7,9,当然1可以直接忽略。 这样我们一次累计抽出2和5后末位是3的数有 多少,末位是7和9的数有多少
上海20【题目大题】 手上最多持有10个,然后把某种纯度的东西放 进箱子,求最少的放进箱子的次数 N<=100
分析
F[k][a][b][c] 表示剩余n-k个,手上三种纯度的 个数分别为a个,b个,c个。
转移
if (k>=n) f[k][a][b][c]=(a>0)+(b>0)+(c>0) Else if (a>0) f[k][a][b][c]=min(f[k][a][b][c],f[k,0,b,c]+1); if (b>0) f[k][a][b][c]=min(f[k][a][b][c],f[k,a,0,c]+1); if (c>0) f[k][a][b][c]=min(f[k][a][b][c],[k,a,b,0]+1);
