Answer the questions below each text by choosing A, B, C or D. Mark your answers on the ANSWER SHEET. (40 points)Text 1First two hours , now three hours-this is how far in advance authorities are recommending people show up to catch a domestic flight , at least at some major U.S. airports with increasingly massive security lines.Americans are willing to tolerate time-consuming security procedures in return for increased safety. The crash of Egypt Air Flight 804,which terrorists may have downed over the Mediterranean Sea ,provides another tragic reminder of why. But demanding too much of air travelers or providing too little security in return undermines public support for the process. And it should: Wasted time is a drag on Americans' economic and private lives, not to mention infuriating.Last year, the Transportation Security Administration (TSA) found in a secret check that undercover investigators were able to sneak weapons---both fake and real-past airport security nearly every time they tried .Enhanced security measures since then, combined with a rise in airline travel due to the improving Chicago's O'Hare International .It is not yet clear how much more effective airline security has become-but the lines are obvious.Part of the issue is that the government did not anticipate the steep increase in airline travel , so the TSA is now rushing to get new screeners on the line. Part of the issue is thatairports have only so much room for screening lanes. Another factor may be that more people are trying to overpack their carry-on bags to avoid checked-baggage fees, though the airlines strongly dispute this.There is one step the TSA could take that would not require remodeling airports or rushing to hire: Enroll more people in the PreCheck program. PreCheck is supposed to be a win-win for travelers and the TSA. Passengers who pass a background check are eligible to use expedited screening lanes. This allows the TSA wants to enroll 25 million people in PreCheck.It has not gotten anywhere close to that, and one big reason is sticker shock. Passengers must pay $85 every five years to process their background checks. Since the beginning, this price tag has been PreCheck's fatal flaw. Upcoming reforms might bring the price to a more reasonable level. But Congress should look into doing so directly, by helping to finance PreCheck enrollment or to cut costs in other ways.The TSA cannot continue diverting resources into underused PreCheck lanes while most of the traveling public suffers in unnecessary lines. It is long past time to make the program work.21. the crash of Egypt Air Flight 804 is mentioned to[A] stress the urgency to strengthen security worldwide.[B] highlight the necessity of upgrading major US airports.[C] explain Americans' tolerance of current security checks.[D] emphasis the importance of privacy protection.22. which of the following contributions to long waits at major airport?[A] New restrictions on carry-on bags.[B] The declining efficiency of the TSA.[C] An increase in the number of travelers.[D] Frequent unexpected secret checks.23.The word "expedited" (Line 4, Para.5) is closest in meaning to[A] faster.[B] quieter.[C] wider.[D] cheaper.24. One problem with the PreCheck program is[A] A dramatic reduction of its scale.[B] Its wrongly-directed implementation.[C] The government's reluctance to back it.[D] An unreasonable price for enrollment.25. Which of the following would be the best title for the text?[A] Less Screening for More Safety[B] PreCheck-a Belated Solution[C] Getting Stuck in Security Lines[D] Underused PreCheck LanesText 2"The ancient Hawaiians were astronomers," wrote Queen Liliuokalani, Hawaii's last reigning monarch, in 1897. Star watchers were among the most esteemed members of Hawaiian society. Sadly, all is not well with astronomy in Hawaii today. Protests have erupted over construction of the Thirty Meter Telescope(TMT), a giant observatory that promises to revolutionize humanity's view of the cosmos.At issue is the TMT's planned location on Mauna Kea, a dormant volcano worshiped by some Hawaiians as the piko , that connects the Hawaiian Islands to the heavens. But Mauna Kea is also home to some of the world's most powerful telescopes. Rested in the Pacific Ocean, Mauna Kea's peak rises above the bulk of our planet's dense atmosphere, where conditions allow telescopes to obtain images of unsurpassed clarity.Opposition to telescopes on Mauna Kea is nothing new. A small but vocal group of Hawaiians and environments have long viewed their presence as disrespect for sacred land and a painful reminder of the occupation of what was once a sovereign nation.Some blame for the current controversy belongs to astronomers. In their eagerness to build bigger telescopes, they forgot that science is the only way of understanding the world. They did not always prioritize the protection of Mauna Kea's fragile ecosystems or its holiness to the island's inhabitants. Hawaiian culture is not a relic of the past; it is a living culture undergoing a renaissance today.Yet science has a cultural history, too, with roots going back to the dawn of civilization. The same curiosity to find what lies beyond the horizon that first brought early Polynesians to Hawaii's shores inspires astronomers today to explore the heavens. Calls to disassemble all telescopes on Mauna Kea or to ban future development there ignore the reality that astronomy and Hawaiian culture both seek to answer big questions about who we are, where we come from and where we are going. Perhaps that is why we explore the starry skies, as if answering a primal calling to know ourselves and our true ancestral homes.The astronomy community is making compromises to change its use of Mauna Kea. The TMTsite was chosen to minimize the telescope's visibility around the island and to avoid archaeological and environmental impact. To limit the number of telescopes on Mauna Kea, old ones will be removed at the end of their lifetimes and their sites returned to a natural state. There is no reason why everyone cannot be welcomed on Mauna Kea to embrace their cultural heritage and to study the stars.26. Queen Liliuokalani's remark in Paragraph 1 indicates[A] its conservative view on the historical role of astronomy.[B] the importance of astronomy in ancient Hawaiian society.[C] the regrettable decline of astronomy in ancient times.[D] her appreciation of star watchers' feats in her time.27.Mauna Kea is deemed as an ideal astronomical site due to[A] its geographical features[B] its protective surroundings.[C] its religious implications.[D] its existing infrastructure.28.The construction of the TMT is opposed by some locals partly because[A] it may risk ruining their intellectual life.[B] it reminds them of a humiliating history.[C] their culture will lose a chance of revival.[D] they fear losing control of Mauna Kea.29.It can be inferred from Paragraph 5 that progress in today's astronomy[A] is fulfilling the dreams of ancient Hawaiians.[B] helps spread Hawaiian culture across the world.[C] may uncover the origin of Hawaiian culture.[D] will eventually soften Hawaiians' hostility.30.The author's attitude toward choosing Mauna Kea as the TMT site is one of[A] severe criticism.[B] passive acceptance.[C] slight hesitancy.[D] full approval.Text 3Robert F. Kennedy once said that a country's GDP measures "everything except that which makes life worthwhile." With Britain voting to leave the European Union, and GDP already predicted to slow as a result, it is now a timely moment to assess what he was referring to.The question of GDP and its usefulness has annoyed policymakers for over half a century. Many argue that it is a flawed concept. It measures things that do not matter and misses things that do. By most recent measures, the UK's GDP has been the envy of the Western world, with record low unemployment and high growth figures. If everything was going so well, then why did over 17 million people vote for Brexit, despite the warnings about what it could do to their country's economic prospects?A recent annual study of countries and their ability to convert growth into well-being sheds some light on that question. Across the 163 countries measured, the UK is one of the poorest performers in ensuring that economic growth is translated into meaningful improvements for its citizens. Rather than just focusing on GDP, over 40 different sets of criteria from health, education and civil society engagement have been measured to get a more rounded assessment of how countries are performing.While all of these countries face their own challenges , there are a number of consistent themes . Yes , there has been a budding economic recovery since the 2008 global crash , but in key indicators in areas such as health and education , major economies have continued to decline . Yet this isn't the case with all countries . Some relatively poor European countries have seen huge improvements across measures including civil society , income equality and the environment.This is a lesson that rich countries can learn : When GDP is no longer regarded as the sole measure of a country's success, the world looks very different .So, what Kennedy was referring to was that while GDP has been the most common method for measuring the economic activity of nations , as a measure , it is no longer enough . It does not include important factors such as environmental quality or education outcomes - all things that contribute to a person's sense of well-being.The sharp hit to growth predicted around the world and in the UK could lead to a decline in the everyday services we depend on for our well-being and for growth . But policymakers who refocus efforts on improving well-being rather than simply worrying about GDP figures could avoid the forecasted doom and may even see progress .31.Robert F. Kennedy is cited because he[A]praised the UK for its GDP.[B]identified GDP with happiness .[C]misinterpreted the role of GDP .[D]had a low opinion of GDP .32.It can be inferred from Paragraph 2 that[A]the UK is reluctant to remold its economic pattern .[B]GDP as the measure of success is widely defied in the UK .[C]the UK will contribute less to the world economy .[D]policymakers in the UK are paying less attention to GDP .33.Which of the following is true about the recent annual study ?[A]It is sponsored by 163 countries .[B]It excludes GDP as an indicator.[C]Its criteria are questionable .[D]Its results are enlightening .34.In the last two paragraphs , the author suggests that[A]the UK is preparing for an economic boom .[B]high GDP foreshadows an economic decline .[C]it is essential to consider factors beyond GDP .[D]it requires caution to handle economic issues .35.Which of the following is the best title for the text ?[A]High GDP But Inadequate Well-being , a UK Lesson[B]GDP Figures, a Window on Global Economic Health[C]Rebort F.Kennedy, a Terminator of GDP[D]Brexit, the UK's Gateway to Well-beingText 4In a rare unanimous ruling, the US Supreme Court has overturned the corruption conviction of a former Virginia governor, Robert McDonnell. But it did so while holding its nose at the ethics of his conduct, which included accepting gifts such as a Rolex watch and a Ferrari automobile from a company seeking access to government.The high court's decision said the judge in Mr. McDonnell's trial failed to tell a jury that it must look only at his "official acts," or the former governor's decisions on "specific" and "unsettled" issues related to his duties.Merely helping a gift-giver gain access to other officials, unless done with clear intent to pressure those officials, is not corruption, the justices found.The court did suggest that accepting favors in return for opening doors is "distasteful" and "nasty." But under anti-bribery laws, proof must be made of concrete benefits, such as approval of a contract or regulation. Simply arranging a meeting, making a phone call, or hosting an event is not an "official act".The court's ruling is legally sound in defining a kind of favoritism that is not criminal. Elected leaders must be allowed to help supporters deal with bureaucratic problems without fear of prosecution for bribery." The basic compact underlying representative government," wrote Chief Justice John Roberts for the court," assumes that public officials will hear from their constituents and act on their concerns."But the ruling reinforces the need for citizens and their elected representatives, not the courts, to ensure equality of access to government. Officials must not be allowed to play favorites in providing information or in arranging meetings simply because an individual or group provides a campaign donation or a personal gift. This type of integrity requires well-enforced laws in government transparency, such as records of official meetings, rules on lobbying, and information about each elected leader's source of wealth.Favoritism in official access can fan public perceptions of corruption. But it is not always corruption. Rather officials must avoid double standards, or different types of access for average people and the wealthy. If connections can be bought, a basic premise of democratic society-that all are equal in treatment by government-is undermined. Good governance rests on an understanding of the inherent worth of each individual.The court's ruling is a step forward in the struggle against both corruption and official favoritism.36. The undermined sentence (Para.1) most probably shows that the court[A] avoided defining the extent of McDonnell's duties.[B] made no compromise in convicting McDonnell.[C] was contemptuous of McDonnell's conduct.[D] refused to comment on McDonnell's ethics.37. According to Paragraph 4, an official act is deemed corruptive only if it involves[A] leaking secrets intentionally.[B] sizable gains in the form of gifts.[C] concrete returns for gift-givers.[D] breaking contracts officially.38. The court's ruling is based on the assumption that public officials are[A] justified in addressing the needs of their constituents.[B] qualified to deal independently with bureaucratic issues.[C] allowed to focus on the concerns of their supporters.[D] exempt from conviction on the charge of favoritism.39. Well-enforced laws in government transparency are needed to[A] awaken the conscience of officials.[B] guarantee fair play in official access.[C] allow for certain kinds of lobbying.[D] inspire hopes in average people.40. The author's attitude toward the court's ruling is[A] sarcastic.[B] tolerant.[C] skeptical.[D] supportivePart BDirections:The following paragraphs are given in a wrong order.

Paragraphs B and D have been correctly placed. Mark your answers on ANSWER SHEET. (10 points)[A]The first published sketch, "A Dinner at Poplar Walk" brought tears to Dickens's eyes when he discovered it in the pages of The Monthly Magazine. From then on his sketches ,which appeared under the pen name "Boz" in The Evening Chronicle, earned him a modest reputation.[B]The runaway success of The Pickwick Papers, as it is generally known today, secured Dickens's fame. There were Pickwick coats and Pickwick cigars, and the plump, spectacled hero, Samuel Pickwick, became a national figure.[C]Soon after Sketches by Boz appeared, a publishing firm approached Dickens to write a story in monthly installments, as a backdrop for a series of woodcuts by the ten-famous artist Robert Seymour, who had originated the idea for the story. With characteristic confidence, Dickens successfully insisted that Seymour's pictures illustrate his own story instead. After the first installment, Dickens wrote to the artist and asked him to correct a drawing Dickens felt was not faithful enough to his prose. Seymour made the change, went into his backyard, and expressed his displeasure by committing suicide. Dickens and his publishers simply pressed on with a new artist. The comic novel, The Posthumous Papers of the Pickwick Club, appeared serially in 1836 and 1837, and was first published in book form in 1837.[D]Charles Dickens is probably the best-known and, to many people, the greatest English novelist of the 19th century. A moralist, satirist, and social reformer. Dickens crafted complex plots and striking characters that capture the panorama of English society.[E]Soon after his father's release from prison, Dickens got a better job as errand boy in law offices. He taught himself shorthand to get an even better job later as a court stenographer and as a reporter in Parliament. At the same time, Dickens, who had a reporter's eye for transcribing the life around him especially anything comic or odd, submitted short sketches to obscure magazines.[F] Dickens was born in Portsmouth, on England's southern coast. His father was a clerk in the British navy pay office -a respectable position, but wish little social status. His paternal grandparents, a steward and a housekeeper possessed even less status, having been servants, and Dickens later concealed their background. Dicken's mother supposedly came from a more respectable family. Yet two years before Dicken's birth, his mother's father was caught stealing and fled to Europe, never to return. The family's increasing poverty forced Dickens out of school at age 12 to work in Warren's Blacking Warehouse, a shoe-polish factory, where the other working boys mocked him as "the young gentleman." His father was then imprisoned for debt. The humiliations of his father's imprisonment and his labor in the blacking factory formed Dicken's greatest wound and became his deepest secret. He could not confide them even to his wife, although they provide the unacknowledged foundation of his fiction.[G] After Pickwick, Dickens plunged into a bleaker world. In Oliver Twist, e traces an orphan's progress from the workhouse to the criminal slums of London. Nicholas Nickleby, his next novel, combines the darkness of Oliver Twist with the sunlight of Pickwick. The popularity of these novels consolidated Dichens' as a nationally and internationally celebrated man of letters.D →41. →42. →43. →44. →B →45.【答案】41. [F] Dickens was born in Portsmouth42.

Your translation should be written neatly on the ANSWER SHEET. (10 points)The growth of the use of English as the world`s primary language for international communication has obviously been continuing for several decades.(46)But even as the number of English speakers expands further there are signs that the global predominance of the language may fade within the foreseeable future.Complex international, economic, technological and culture change could start to diminish the leading position of English as the language of the world market, and UK interests which enjoy advantage from the breath of English usage would consequently face new pressures. Those realistic possibilities are highlighted in the study presented by David Graddol(47)His analysis should therefore end any self-contentedness among those who may believe that the global position of English is so stable that the young generation of the United Kingdom do not need additional language capabilities.David Graddol concludes that monoglot English graduates face a bleak economic future as qualified multilingual youngsters from other countries are proving to have a competitive advantage over their British counterparts in global companies and organizations. Alongside that,(48)many countries are introducing English into the primary-school curriculum but British schoolchildren and students do not appear to be gaining greater encouragement to achieve fluency in other languages.If left to themselves, such trends will diminish the relative strength of the English language in international education markets as the demand for educational resources in languages, such as Spanish ,Arabic or Mandarin grows and international business process outsourcing in other language such as Japanese, French and German, spreads.(49)The changes identified by David Graddol all present clear and major challenges to UK`s providers of English language teaching to people of other countries and to broader education business sectors. The English language teaching sector directly earns nearly &1.3 billion for the UK in invisible exports and our other education related explores earn up to &10 billion a year more. As the international education market expands, the recent slowdown in the number of international students studying in the main English-speaking countries is likely to continue, especially if there are no effective strategic policies to prevent such slippage.The anticipation of possible shifts in demand provided by this study is significant:(50) It gives a basis to all organization which seek to promote the learning and very different operating environment. That is a necessary and practical approach. In this as in much else, those who wish to influence the future must prepare for it.【答案】(46) 但是即使当下英语使用者的人群还在进一步扩大，有迹象表明：在可预见的未来，英语可能会逐渐失去其全球主导地位。

小学奥数五年级模拟题1一、填空题，共31 题，每题3分1、从左向右编号为1至1991号的1991名同学排成一行,从左向右1至11报数,报数为11的同学原地不动,其余同学出列;然后留下的同学再从左向右1至11报数,报数为11的留下,其余同学出列;留下的同学第三次从左向右1至11报数,报到11的同学留下,其余同学出列,那么最后留下的同学中,从左边数第一个人的最初编号是_____号.【答案】1331;【解析】第一次报数后留下的同学最初编号都是11倍数;第二次报数后留下的同学最初编号都是121 的倍数;第三次报数后留下的同学最初编号都是1331的倍数.所以最后留下的只有一位同学,他的最初编号是1331.2、四位数“3AA1”是9的倍数，那么A=_____.【答案】7;【解析】已知四位数3AA1正好是9的倍数,则其各位数字之和3+A+A+1一定是9的倍数,可能是9的1倍或2倍,可用试验法试之.设3+A+A+1=9,则A=2.5,不合题意.再设3+A+A+1=18,则A=7,符合题意.事实上,3771 9=419.3、在下式样□中分别填入三个质数,使等式成立.□+□+□=50【答案】2、5、43;【解析】接近50的质数有43,再将7分拆成质数2与质数5的和.即2+5+43=50另外,还有2+19+29=502+11+37=50[注]填法不是唯一的.如也可以写成41+2+7=504、今有10个质数:17,23,31,41,53,67,79,83,101,103.如果将它们分成两组,每组五个数,并且每组的五个数之和相等,那么把含有101的这组数从小到大排列,第二个数应是_____.【答案】31;【解析】这10个质数之和是598,分成两组后,每组五个数之和是598 2=299.在有79这组数中,其他四个质数之和是299-79=220,个位数是0,因此这四个质数的个位数可能有三种情形:(1)三个1和一个7；(2)二个3和二个7；(3)三个3和一个1.31+41+101=173,220-173=47,可这十个数中没有47,情形(1)被否定.17+67=84,220-84=136,个位数为3有23,53,83,只有53+83=136,因此从情形(2)得到一种分组:17,53,67,79,83和23,31,41,101,103.所以,含有101这组数中,从小到大排列第二个数是31.[注]从题目本身的要求来说,只要找出一种分组就可以了,但从情形(3)还可以得出另一种分组.23+53+83+103=262,262-220=42, 我们能否从53,83,103中找出一个数,用比它少42的数来代替呢?53-42=11,83-42=41,103-42=61.这十个数中没有11和61,只有41.又得到另一种分组:23,41,53,79,103和17,31,67,83,101.由此可见,不论哪一种分组,含101这组数中,从小到大排列,第二个数都是315、28的所有因数之和是_____.【答案】56;【解析】28的约数有1,2,4,7,14,28,它们的和为1+2+4+7+14+28=566、用105个大小相同的正方形拼成一个长方形,有_____种不同的拼法.【答案】4;【解析】因为105的约数有1,3,5,7,15,21,35,105能拼成的长方形的长与宽分别是105和1,35和3,21与5,15与7.所以能拼成4种不同的长方形.7、a 24=121……b,要使余数最大，被除数应该等于_____.【答案】2927;【解析】因为余数一定要比除数小,所以余数最大为23,故有被除数=24121+23=29278、小东在计算除法时，把除数87写成78，结果得到的商是54，余数是8.正确的商是_____,余数是_____.【答案】48;44;【解析】依题意得：被除数=78 54+8=4220而4220=87 48+44,所以正确的商是48,余数是449、五个连续奇数的和是85，其中最大的数是_____,最小的数是_____.【答案】21;13;【解析】这五个数的中间数85 5=17,可知最大数是21,最小数是1310、三个质数=_____.【答案】2;【解析】11、流水线上生产小木珠涂色的次序是:先5个红,再4个黄,再3个绿,再2个黑,再1个白,然后再依次是5红,4黄,3绿,2黑,1白,……继续下去第1993个小珠的颜色是_____色.【答案】黑;【解析】小木球是依次按5红,4黄,3绿,2黑和1白的规律涂色的,把它看成周期性问题,每个周期为15由1993 15=132…13知，第1993个小球是第133周期中的第13个，按规律涂色应该是黑色，所以第1993个小球的颜色是黑色.12、把珠子一个一个地如下图按顺序往返不断投入A、B、C、D、E、F袋中.第1992粒珠子投在_____袋中.【答案】B;【解析】通过观察可以发现,第11次到第20次投进的袋子依次与第1次到第10次投进的袋子相同,即当投的次数被10除余1,2,3,…，8，9，0，分别投进A，B，C，……D，C，B袋中，1992被10除余2，所以第1992粒珠子投在B袋中.13、如下图,方格纸上放了20枚棋子,以棋子为顶点的正方形共有_____个.【答案】21;【解析】以正方形的面积大小分类计数.设相邻两点的距离为1，则正方形面积为1的有9个；面积为2的有4个；面积为5的有2个；面积为8的有4个；面积为13的有2个；所以，共有9+4+2+4+2=21个正方形.14、人的血型通常为A型,B型,O型,AB型.子女的血型与其父母血型间的关系如下表所示:现有三个分别身穿红,黄,蓝上衣的孩子,他们的血型依次为O,A,B.每个孩子的父母都戴着同颜色的帽子,颜色也分红,黄,蓝三种,依次表示所具有的血型为AB,A,O.那么穿红、黄、蓝上衣的孩子的父母戴帽子的颜色是、、.【答案】蓝、黄、红.;【解析】解法一题中表明,每个孩子的父母是同血型的.具有B型血的孩子,其父母同血型时,由表中可见,只能是B型或AB型,但题中没有同具B型血的父母,所以戴红帽子的父母的孩子穿蓝上衣.具有A 型血的孩子的同血型的父母,只可能同为A型血或同为AB型血.今已知有一对父母为AB型血者,所以穿黄上衣的孩子的父母戴黄帽子.由表中可见,其孩子为O型血时,父母血型只能同为A型或B型或O型.今已知不具有同为B型血的父母,而同为A型血的父母的孩子已知具有A型血.把代表孩子的点与他的可能双亲的代表点之间连一直线段,便可得下面的图；由于孩子与其父母之间是唯一搭配的,所以,保存下来的只有连着红、蓝；黄，黄及蓝，红的三条边.所以,穿红上衣(O型血)孩子的父母戴蓝帽子.所以,穿红上衣的孩子的父母戴蓝帽子；穿黄上衣的孩子的父母戴黄帽子；穿蓝上衣的孩子的父母戴红帽子.15、六年级六个班组织乒乓球单打比赛,每班派甲、乙两人参赛，根据规则每两人之间至多赛一场，且同班的两人之间不进行比赛.比赛若干场后发现,除一班队员甲以外,其他每人已比赛过的场数各不相同,那么一班队员乙已赛过____场.【答案】5;【解析】根据题意,有11名队员比赛场数各不相同,并且每人最多比赛10场,所以除甲外的11名队员比赛的场数分别为0~10已赛10场的队员与除已赛0场外的所有队员都赛过,所以已赛10场的队员与已赛0场的队员同班；已赛9场的队员与除已赛0、1场外的所有队员都赛过,所以已赛9场的队员与已赛1场的队员同班；同理,已赛8、7、6场的队员分别与已赛2、3、4场的队员同班；所以甲与已赛5场的队员同班,即乙赛过5场.16、找规律,填得数.【解析】111111111,4; 12345678987654321,4;49382715950617284.根据已知等式的观察和分析,可知算式演变规律有两种形式: 其一是等积恒变;其二是17、图中第1格内放着一个立方体木块,木块六个面上分别写着六个字母,其中与与与相对.如果将木块沿着图中方格滚动,当木块滚动到第21个格时,木块向上的面写的字母是______.【答案】A.;【解析】木块沿直线滚动4格,与原来的状态相同,所以木块到第5,9,13,21格时,与在第1格的状态相同,写的字母是A.18、两列对开的火车途中相遇,甲车上的乘客从看到乙车到乙车从旁边开过去,共用6秒钟.已知甲车每小时行45千米,乙车每小时行36千米,乙车全长_____米.【答案】135;【解析】根据相向而行问题可知乙车的车长是两车相对交叉6秒钟所行路之和.所以乙车全长19、甲、乙两地间的路程是600千米,上午8点客车以平均每小时60千米的速度从甲地开往乙地.货车以平均每小时50千米的速度从乙地开往甲地.要使两车在全程的中点相遇,货车必须在上午______点出发.【答案】7;【解析】根据中点相遇的条件,可知两车各行600×=300(千米).其间客车要行300÷60=5(小时);货车要行300÷50=6(小时).所以,要使两车同时到达全程的中点,货车要提前一小时出发,即必须在上午7点出发.20、当甲在60米赛跑中冲过终点线时，比乙领先10米、比丙领先20米，如果乙和丙按原来的速度继续冲向终点，那么当乙到达终点时将比丙领先米.【答案】12;【解析】解法一依题意,画出线段图如下:在同样时间内,甲跑60米,乙跑50米,丙跑40米,也就是在相同单位时间内甲跑6米,乙跑5米,丙跑4米.所以,由上图看出,当乙跑10米到达终点时,丙又跑了8米,此时丙距终点60-40-8=12(米)解法二相同时间内,乙跑50米,丙跑40米,所以丙速是乙速的.因此当乙到达终点时,丙的行程为60´ =48(米)此时丙距终点60-48=12(米)解法三由于乙、丙两人速度不变,又丙与乙在第一段时间内的路程差(50-40)=10米是乙的路程的10¸50= ,所以当乙跑完后10米时,丙在第二段时间与乙的路程差为10´=2(米)两次路程差和10+2=12(米),就是乙比丙领先的路程.21、一只兔子奔跑时,每一步都跑0.5米；一只狗奔跑时,每一步都跑1.5米.狗跑一步时,兔子能跑三步.如果让狗和兔子在100米跑道上赛跑,那么获胜的一定是.【答案】兔子.;【解析】从题面上看,狗和兔子的速度是一样的,但因为当狗跑了66步后,狗共跑了99米,剩下1米,这时它也得再花一步的时间,这相当于狗要往反100.5米,而当狗跑了66步后,兔子跑了(3´66)=198步,再花2步的时间,即到达终点.所以狗较慢.兔子一定获胜.22、口袋里装有99张小纸片,上面分别写着1~99.从袋中任意摸出若干张小纸片,然后算出这些纸片上各数的和,再将这个和的后两位数写在一张新纸片上放入袋中.经过若干次这样的操作后,袋中还剩下一张纸片,这张纸片上的数是_____.【答案】50;【解析】每次操作都不改变袋中所有数之和除以100的余数,所以最后一张纸片上的数等于1~99的和除以100的余数.故这张纸片上的数是5023、用1~10十个数随意排成一排.如果相邻两个数中,前面的大于后面的,就将它们变换位置.如此操作直到前面的数都小于后面的数为止.已知10在这列数中的第6位,那么最少要实行_____次交换.最多要实行_____次交换.【答案】4次；40次.;【解析】当排列顺序为1,2,3,4,5,10,6,7,8,9时,交换次数最少,需交换4次；当排列顺序为9，8，7，6，5，10，4，3，2，1时，交换次数最多，需交换40次.24、分数、、、从小到大排列为.【答案】、、、.;25、有分母都是7的真分数、假分数和带分数各一个，它们的大小只差一个分数单位.这三个分数分别是.【答案】; ; ;26、1～1991这1991个自然数中,所有的奇数之和与所有的偶数之和的差是______.【答案】996;【解析】27、计算:1-3+5-7+9-11+…-1999+2001=______.【答案】1001;【解析】28、将某数的3倍减5,计算出答案,将答案再3倍后减5,计算出答案,这样反复经过4次,最后计算的结果为691,那么原数是_____.【答案】11;【解析】11从最后的结果往前逆推,结果是691,这是一个数的3倍减5得到的,这个数应该是(691+5) 3=232,这是经过3次后的结果；同样可知,经过2次后的结果为(232+5)3=79；经过1次后的结果为(79+5) 3=28；因此,原数为(28+5) 3==1129、李老师拿着一批书送给36位同学,每到一位同学家里,李老师就将所有的书的一半给他,每位同学也都还她一本,最后李老师还剩下2本书,那么李教师原来拿了_____本书.【答案】2;【解析】2最后李老师还剩2本书,因此,他到第36位同学家之前应有(2-1) 2=2本书；同样,他到35位同学家之前应有(2-1) 2=2本书;…；由上此可知,他到每位同学家之前都有2本书,故李老师原来拿了2本书.30、一把钥匙只能开一把锁.现在有4把钥匙4把锁,但不知哪把钥匙开哪把锁,最多要试次才能配好全部的钥匙和锁.【答案】6;【解析】第一把钥匙最坏的情况要试3次,第二把要试2次,第三把要试1次,共计6次.31、用长和宽分别是4厘米和3厘米的长方形小木块,拼成一个正方形,最少要用这样的木块块.【答案】12;【解析】因4和3的最小公倍数为12,故最少需这样的木块12块.二、解答题，共7 题，每题2分1、1.996+19.97+199.8【答案】221.766;【解析】原式=(2-0.004)+(20-0.03)+(200-0.2)=222-(0.004+0.03+0.2)=221.7662、6.11+9.22+8.33+7.44+5.55+4.56+3.67+2.78 +1.89【答案】49.55;3、有一个数，除以3余数是1，除以4余数是3，这个数除以12余数是_____.【答案】7;【解析】因为除以3余数是1的数是1,4,7,10,13,16,19,22,25,28,31,…除以4余数是3的数是3,7,11,15,19,23,27,31…所以，同时符合除以3余数是1，除以4余数是3的数有7，19，31，…这些数除以12余数均为74、有一盒乒乓球，每次8个8个地数，10个10个地数，12个12个地数，最后总是剩下3个.这盒乒乓球至少有多少个?【答案】123;【解析】如果这盒乒乓球少3个的话,8个8个地数,10个10个地数,12个12个的数都正好无剩余,也就是这盒乒乓球减少3个后是8,10,12的公倍数,又要求至少有多少个乒乓球,可以先求出8,10,12的最小公倍数,然后再加上3故8,10,12的最小公倍数是2 2 2 5 3=120.所以这盒乒乓球有123个5、下图中,AB、CD、EF、MN互相平行，则图中梯形个数与三角形个数的差是多少？【答案】20;【解析】解法一本图中三角形的个数为(1+2+3+4) 4=40(个).下面求梯形的个数.梯形由两底唯一确定.首先在AB,CD,EF,MN中,考虑两底所在的线段,共有(4 3) 2=6(种)选法；对上述四条线段中确定的两条线段，共有10（10=4+3+2+1）个梯形.共60个梯形.故所求差为20.解法二在图中可数出4个三角形,6个梯形,梯形比三角图形图形多2个.而在题图中,这种恰有10个.故题图中,梯形个数与三角形的个数之差为2 10=20(个).6、计算:1996+1995-1994-1993+1992+1991-1990-1989+…+4+3-2-1,结果是____.【答案】1996;【解析】从左至右每四个数运算的结果都是47、在下面的一列数中,只有一个九位数,它是______.1234,5678,9101112,13141516,……【答案】979899100;【解析】按照自然数从小到大的顺序,每四个数构成一数.九位数只能由三个两位数和一个三位数构成,所以这个九位数是979899100。

For each questions there are four choices marked A, B, C and D. You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the center.Passage 1College is a new and different experience for me. I'm away from home, so I have many things to adjust to, e.g. being on my own, talking with friendly people. These are some of the things I like about college.First of all, living at college gives me a sense of responsibility, of being on my own. My parents aren't around to say, "No, you'renot going out tonight." or "Did you finish your homework?" Everything I do has to be my decision, and that makes me responsible for my own life. During the second week I was at college, I had to go out and look for a bank where I could open an account. And when I got to the bank, I had to decide whether to have a current or savings account and whether or not to get a credit card. Decisions! Decisions!Friendly people, that's another thing I like about college. On my first day I came to Marymount University here in Virginia from New York, I was a bit confused about where I was going. My mother and I drove in. We did not know the building we were supposed to go to, but the guard was very nice. With a smile, he told us what building we were looking for and where we could park our car. My room was on the first floor of New Gerard, and I knew I had to go through some glass doors, but my mother and I didn't know which ones. Some students saw me and asked, "Are you a new student?" When they found out I was looking for New Gerard, one said: "Oh, just follow us; that's where we're going." Even now I feel comfortable in the dorm because there are friendly people around to talk with.I do like a lot of things about college, but that doesn't mean I don't think about things at home. Although I like college, I can still get homesick: New York is a very good place, too!31.The text is perhaps written by ____a____.A.a new studentB. a new teacherC. a foreign reporterD.a foreign visitor32. What does "gives me a sense of responsibility" in the first sentence of Paragraph 2mean? It means ___d_____.A. I shall be responsible for my parentsB. I shall be responsible for my teacherC. I shall be responsible for the schoolD. I shall be responsible for myself33. From Paragraph 3 we know that ____d____.A. the writer knew Marymount University quite wellB. the writer was a student from VirginiaC. the writer came to Marymount University aloneD. the writer liked his/her dorm very much34. What is New Gerard?cA. It's a student's name.B. It's a teacher's nameC. It's a dorm's name.D. It's a school's name.35. Which of the following is NOT true?dA. People in Marymount University are friendly.B. The writer likes the new experience in the university.C. The writer drove to Marymount University on the first day.D. The writer is not homesick.Passage 2At the center of our solar system is a star called the Sun. It is a ball of very hot gases. Its diameter is more than 100 times as big as that of the Earth. It gives off powerful rays of light in the form of radiant energy. This energy travels to the Earth at a speed of approximately 300,000 kilometers per second. This means that sunlight takes 8.33 minutes to get to the Earth.The temperature on the surface of the Sun is about 5,520°C, and it is much hotter inside. Scientists now believe that the heat of the Sun comes from natural atomic energy. In this process,hydrogen is believed to be changed to helium (氦) with an enormous amount of energy given off. The mass (matter) is changed to energy. This energy is in the form of heat, light, and other forms of radiation.36. The author makes all of the following statements about the Sun EXCEPT that it___d___.A.is a starB.emits light raysC.is made up of gassesD.is more than 100 times heavier than the Earth37. It can be inferred from the passage that the temperature of the outer rim (缘) of theSun is ___b___.A.hotter than the Earth’s interiorB.cooler than the Sun’s interiorC.as hot as the Earth’s interiorD.as hot as the Sun’s interior38. The author implies that scientists at one time did not believe that atomic energywas ___a___.A.the source of the Sun’s heatB.contained in the Earth’s coreC.able to travel at the speed of lightD.less powerful than solar energy39. According to the passage, which of the following best describes the manner inwhich the Sun is thought to produce energy?dA.Helium heats hydrogen, which gives off light.B.Heat and light melt hydrogen, which produces helium.C.Light produces hydrogen and helium, which gives off energy.D.Hydrogen turns into helium, which gives off light and heat.40. Which of the following would be the best title for the passage?dA.The Sun --- the Largest Star in the Sky.B.The Sun --- The Brightest Star in the Sky.C.The Sun --- Ball of Hot Gasses.D.The Sun --- Great Source of Energy.Passage 3In 1920, after some thirty-nine years of problems with disease, high costs, and politics, the Panama Canal was officially opened, finally linking the Atlantic and Pacific Oceans by allowing ships to pass through the fifty-mile canal zone instead of traveling some seven thousand miles around Cape Horn. It takes a ship approximately 8 hours to complete the trip through the canal and costs an average of fifteen thousand dollars, one-tenth of what it would cost an average ship to round the Horn. More than fifteen thousand ships pass through its locks (船闸) each year.The French initiated the project but sold their rights to the United States. The latter will control it until the end of the twentieth century when Panama takes over its duties.41. Who currently controls the Panama Canal?cA. FranceB. PanamaC. the United SatesD. the Canal Zone42. Which is NOT mentioned as one of the difficulties met during the building of thePanama Canal?cA.There were many dispute among politicians.B.There was not enough fund for the project.C.It took too much time to complete the canal.D.A lot of workers were taken ill.43. On the average, how much would it cost a ship to travel around Cape Horn?bA. $150.B. $150,000C. 15,000D. $1,50044. In what year was construction probably begun on the canal?aA. 1881B. 1939C. 1920D. 189945. Which of the following statements is true according to the passage?dA.The canal brought about new diseases to the canal zone.B.Most of the workers came from France during the early stage of the project.C.Before the canal was constructed, ships traveling from the Pacific to theAtlantic had to pay a lot more money to Panama government.D.A different government will take control of the canal around 2000.Part IV Vocabulary and Structure (25 points)Section ADirections:In this section there are 15 incomplete sentences.

Then mark the corresponding letter on the Answer Sheet with a single line through the center.And so there are many similarities between the teacher’s work and the actor’s. However, the fact that a good teacher has some of the gifts of a good actor 61 that he will indeed be able to act well on the stage; for there are very important differences 62 the teacher’s work and the actor’s work. The actor has to speak words which he ahs learned 63 ; he has to repeat exactly the same words each time he plays a certain part; 64 his movements and the way in which he uses his voice are usually fixed 65 . What he has to do is to make all these carefully learned words and actions seem natural on the stage.The good teacher works in 66 different way. His audience takes an active part in his play, they ask and answer questions, they 67 orders, and if they do not understand something, they say so. The teacher therefore has to suit his act 68 the need of his audience which is his class. He cannot keep his part in mind, but must 69 it as he goes along.I have known many teachers who were fine actors in class but were unable to play a part in a stage-play because their brains would not keep discipline; they could not keep strictly to 70 .c61.
