(19分)(牛)徽举进士，累擢．吏部员外郎。

乾符中选滥，吏多奸，岁调四千员，徽治以刚明，柅杜干请，法度复振。

(牛)蔚避地于梁，道病，徽与子扶篮舆，历阁路，盗击其首，血流面，持舆不息。

盗迫之，徽拜曰：“人皆有父，今亲老而疾，幸无骇惊。

〞盗感之，乃止。

及前谷，又逢盗，辄相语曰：“此孝子也！〞一共举舆舍之家，进帛裹创，以饮奉蔚，留信宿去。

抵梁，徽趋蜀谒行在，丐归侍亲疾。

会拜谏议大夫，固辞，见宰相杜让能曰：“上迁幸当从，亲有疾当侍，而徽兄在朝廷，身乞还营医药。

〞时兄循已位给事中，许之。

父丧，客梁、汉。

终丧，以中书舍人召，辞疾，改给事中，留陈仓。

张濬伐，引为判官，敕．在所敦遣。

徽太息曰：“王室方复，廥藏殚耗，当协和诸侯．．以为藩屏，而又济以兵，诸侯离心，必有后忧。

〞不肯起。

濬果败。

复召为给事中。

杨复恭叛，李茂贞请假招讨节伐之，未报，而与王行瑜辄出兵。

昭宗怒，持奏不下。

茂贞亟请，帝召群臣议，无敢言。

徽曰：“王室多难，茂贞诚有功。

今复恭阻兵而讨之，罪在不俟命尔。

臣闻两镇兵多杀伤，不早有所制，那么梁、益之人尽矣。

请假以节，明约束，那么HY有所畏。

〞帝曰：“然。

〞乃以招讨使．．．授茂贞，果有功，然益偃蹇，帝使宰相杜让能将兵诛讨，徽谏曰：“岐，国西门。

茂贞凭其众而暴，假设令万分一不利，屈威重奈何？愿徐制之。

〞不听。

师出，帝复召徽曰：“今伐茂贞，彼众乌合，取必万全，卿计何日有捷？〞对曰臣职谏争所言者HY国大体如索贼平之期愿陛下考蓍龟责将帅非臣职也既而师果败遂杀大臣王室益弱。

There are a set of commonly __32__ gestures but many are influenced by our social settings. Although this article __33__ on interpretations（解释）of human body language, also animals use body language as a communication mechanism（机制）. Body language is typically subconscious（潜意识的）behavior, and is therefore __34__ to be different from sign language, which is a __35__ conscious（有意识的）and intentional（故意的）act of communication.Body language may provide __36__ as to the attitude or state of mind of a person. For example, it may indicate aggression, __37__, boredom, a relaxed state, pleasure and amusement. However, the value of body language in recognizing cheat has been called into question.2Body language is very important to communication ad relationships.

Fill in each blank with the word or phrase that best fits the context.It is natural that young people are often uncomfortable when they are with their parents. They say that their parents don’t __41__ them. They often think that their parents are out of touch with modern ways; that they are too __42__ and too strict with their children; and they seldom give their children a __43__ hand. It is true that parents often find it difficult to win their children’s trust and they tend to forget how they themselves felt when __44__.For example, young people like to act on the spot without much thinking. It is one of their ways to __45__ that they have grown up and they can face any difficult situation. Older people worry more easily. Most of them plan things ahead, at least in the back of their minds, and do not like their plans to be upset by something __46__.3When you want your parents to let you do something, you will be more __47__ if you ask for their permission before you really start doing it.Young people often make their parents angry at their __48__ in clothes, in entertainment and music. But they do not mean to __49__; it is just that they feel cut off from the older people’s world, into which they have not yet been __50__. That’s why young people want to make a new culture of their own. And if their parents do not like music or entertainment or clothiers or their way of speech, this will make the young people extremely happy.Sometimes you are so __51__ yourself that you do not want your parents to say “yes” to what you do. All you want is to be left alone and do what you like. It is __52__ enough, after being a child for so many years, when you where __53__ under your parents’ control.If you plan to control your __54__, you’d better win your parents over and try to get them to understand you. If your parents see that you have a high sense of __55__, they will certainly give you the right to do what you want to do.41. A. protect B. spare C. understand D. guide42.

They often stand close when talking and it is common for them to touch the person on the shoulder. People often greet each5other (particularly women) with light check kisses. Schedules tend to be flexible, with business meetings sometimes starting later than planned. But to be safe, be on time. Meals can stretch for hours -- there’s no such thing as rushing a meal in Brazil Lunches also can start in the mid to late afternoon Brazilians are social, preferring face-to-face communication over mails or phone calls.In SingaporeSingaporeans shake hands when they meet and often also greet each other with a small, polite bow. Business cards should be offered and received with two hands. Arriving late is considered disrespectful. So be on time. Efficiency（效率）is the goal, so meetings and dealings often are fast-paced. Singaporeans are direct in their discussions, even when the subject is about money. Rank is important and authority is respected. This determines both people react in meetings. For example, people avoid disagreeing outright with someone with a higher rank.In the United Arab EmiratesIn the UAE, status（地位）is important, so the most senior or oldest should be greeted first with their titles. The handshake seems to be longer than elsewhere. So, do not pull away the handshake. Women should cover themselves when it comes to dress. Men also tend to be covered from neck to elbows（肘部）and down to the knees. People do not avoid entertaining in their homes, but they also hold business meals at restaurants. Touching or passing food or eating with your left hand is to be avoided. When meetings are one-to-one, if your host offers you coffee, you should refuse. It might seem odd, but it is a cultural tradition. Coffee should6only be accepted if it is always set out or presented.In SwitzerlandThe Swiss tend to be formal and address each other by last name. They also are respectful of private lives. You should be careful not to ask about personal topics. Punctuality（守时）is vital, something that comes from a deep respect for others’time. Arrive at any meeting or event a few minutes early to be safe. They also have clear structure in their companies. Higher-ups make the final decisions, even if others might disagree. Neat, clean dress is expected. The Swiss follow formal table manners. they also keep their hands visible at the table and their elbows off the table. It is polite to finish the food on your plate.59. The passage is mainly about _______.A. communication typesB. the workplace atmosphereC. customs and social mannersD. living conditions and standards60. Why do Singaporeans avoid arguing with their boss?A. They put efficiency in the fist place.B. They dislike face-to-face communication.C. They want to finish meeting as quickly as possible.D. They are supposed to obey the person of a higher rank.761. In the UAE, when should you refuse the coffee if it is offered?A. When greeting seniors.B. When meeting the host alone.C. When attending a presentationD. When dining with business partners.62. In which country do people care about where to put their hands at the dinner table?A. In Brazil.B. In Singapore.C. In the United Arab Emirate.D. In Switzerland.(C)HAPPY to help or too selfish to share - some scientists wonder whether generosity（慷慨大方）lies in our upbringing or in our genes（基因）.In a social science experiment carried out in an Israeli children’s playroom, 136 children aged 3 and 4 years old were given six sets of colorful stickers. They were told: “ You can keep all of the stickers, or you can give some to another child you don’t know. He doesn’t have any stickers,”Researchers then asked the children to step into the playroom one at a time and watched how they behaved.About two thirds of the children chose to give one or more sets of stickers to an unknown child. The others refused to share. Researchers found that many of this second group of children had something in common: a variation（变异）in a gene known as AVPRIA. This gene is supposed to control a chemical in the brain responsible for social behavior. The genetic variant（变体）of this gene can make people a lot less willing to share.8。

Totally loving. No ifs, ands or buts.The idea had come to me as I listened to a talk on my car radio. The speaker was quoting a Biblical (圣经的) passage about husbands being thoughtful of their wives. Then he went on to say, "Love is an act ofwill.A person can choose to love." To myself, I had to admit that I had been a selfish husband. Well, for two weeks that would change.And it did. Right from the moment I kissed Evelyn at the door and said, "That new yellow sweater looks great on you. "Oh, Tom, you noticed," she said, surprised and pleased, maybe a little puzzled.After the long drive, I wanted to sit and read. Evelyn suggested a walk on the beach. I started to refuse, but then I thought, "Evelyn's been alone here with the kids all the week and now she wants to stay with me." We walked on the beach while the children flew their kites.So it went. Two weeks of not calling the Wall Street firm where I am a director; a visit to the shell museum though I usually hate museums. Relaxed and happy, that's how the whole vacation passed. I made a new pledge to keep on remembering to choose love.There was one thing that went wrong with my experiment, however. Evelyn and I still laugh about it today.Last night at our cottage, preparing for bed, Evelyn stared at me with the saddest expression." What's the matter" I asked her."Tom," she said in a voice filled with distress, "do you know something I don't""What do you mean"" Well...that checkup (体检) I had several weeks ago...our doctor (i)he tell you something about meTom, you've been so good to me...am I dying"It took a moment for it all to sink in. Then I burst out laughing."No, honey," I said, wrapping her in my arms. "You're not dying; I'm just starting to live."76. In the first paragraph, "No ifs, ands or buts" probably means ____.A. UnnecessarilyB. unconditionallyC. impossiblyD. unexpectedly77. During the two weeks on the beach, Tom showed more love to his wife because _____.A. she looked lovely in her new clothesB. she was seriously illC. he was determined to be a good husbandD. he had made a lot of money in Wall Street78.By saying "I'm just starting to live", Tom means that _____.A. he is beginning to feel regretful for what he did to his wifeB. he lived an unhappy life before and is now starting to changeC. he is just beginning to understand the real meaning of lifeD. he is just beginning to enjoy his life as a loving husband(B)As I was thinking about language learning the other day, the image of baking bread came into my mind．I compared some of the exercises and drills that we put ourselves through in order to learn a language to the various ingredients (原料) that go into baking a loaf of fresh bread．Real language learning takes place in human relationships．No one sits down and eats a cup of flour, even if he is hungry and in a hurry．You don' t become bilingual (双语的) by learning lists of vocabulary．You don' tbecome a speaker of a language by memorizing grammatical rules．You become bilingual by entering a community that uses that other language as its basic means of communication．I am not suggesting that we can make bread without ingredients．Flour is necessary, as are yeast (酵母), salt, water and other ingredients．Vocabulary is part of any language and will have to be learned．Grammatical rules exist in every language and cannot be ignored．But merely combining the appropriate ingredients in the recommended proportions does not result in bread．At best, you only end up with a ball of dough (⾯团)．In order to get bread, you have to apply heat to the dough．And in language learning, that heat comes from the community．Anyone who has learned a second language has experienced that heat．It creeps up your neck when you ask the babysitter “Have you already been eaten” when you meant to say, ‘‘Have you already eaten” When you try to say something quite innocent and the whole room bursts into laughter, you are experiencing the heat that turns raw dough into good bread．Remember the old saying, “If you can' t stand the heat, get out of the kitchen"．This is where language learning often breaks down because we find the heat uncomfortable and we stop the baking process．In other words, we can' t stand the heat, so we get out of the kitchen．However, the language learner who stays in the kitchen－in the heat－until the combined ingredients are thoroughly transformed will enjoy the richness of a quality loaf of bread. He is glad that he did not "get out of the kitchen” at the importantmoment when the oven seemed too hot.The dedicated language learner knows that becoming bilingual cannot be achieved without the heat.79.According to the author, you can possibly become a speaker of a language by ________．A．bearing millions of words and expressions in your mindB．using the language to communicate with those around youC．Knowing verb conjugations and grammatical rulesD．saying something innocent to be laughed at by others80.'What’s the purpose of illustration of the example-you ask the babysitter,"Have you already been eaten"When you meant to say,"Have you already eaten"A. To verify that you are sure to make some mistakes when you enter a community.B.To show that you should combine the ingredients in the recommended proportions.C. To prove that you may experience"heat"from the community in language learning.D. To indicate that being bilingual calls for your courage, confidence and perseverance.81.According to the passage, which of the following is NOT the necessity of baking bread and learning language? A．Excellent Skills．B．Various ingredients．C．Appropriate proportions．D．Uncomfortable heat．(C)Like most people, I’ve long understood that I’ll be judged by my occupation, that my profession is used by people to see how talented I am. Recently, however, I was disappointed to see that it also decides how I’m treated as a person.Last year I left a professional position as a small-town reporter and took a job waiting tables. As someone paid to serve food to people, I had customers say and do things to me I suppose they’d never say or do to the people they know. One night a man talking on his cell phone waved me away,then called me back with his finger a minute later, saying angrily that he was ready to order and asking where I’d been.I had waited tables during summers in college and was treated like a peon（勤杂⼯） by plenty of people. But at 19 years old, I believed I deserved inferior（低等的）treatment from professional adults. Besides, people responded to me differently after I told them I was in college. Customers would joke that one day I’d be sitting at their table, waiting to be served.Once I graduated I took a job at a community newspaper. From my first day, I heard a respectful tone from everyone who called me. I assumed this was the way the professional world worked--- politely and formally.I soon found out differently. I sat several feet away from a person in advertising department with a similar name. Our calls would often get mixed up and someone asking for Kristen would be transferred to Christie. The mistake was immediately clear. Perhaps it was because of money, but people used a tone with Kristen that they never used with me.My job title made people treat me with courtesy. So it was a shock to return to be the restaurant industry.It’s no secret that there’s a lot to put up with when waiting tables, and fortunately, much of it can be easily forgotten when you pocket the tips. The service industry exists to meet others’ needs. Still, it seemed that many of my customers didn’t get the difference between server and servant.I’m now applying to graduate school, which means someday I’ll return to a profession where people need to be nice to me in order to get what they want. I think I’ll take them to dinner first, and see how they treat someone whose job is to serve them.82.The author was disappointed to find that_____________83.A. one’s position is used to measure one’s intelligence.B. Talented people like her should fail to get a respectable jobC. one’s occupation affects the way one is treated as a person.D. professionals tend to look down upon manual workers.83. What does the author intend to say by the example in Paragraph 2A. Waiting tables is a hard job.B. Some customers are difficult to deal with.C. The man making a phone call is absent-minded.D. Some customers show no respect to those who serve them.84.What does the author imply by saying"... Many of my customers didn’t get the difference between server and servant (Lines 3-4, Para. 7)A.

The author says one day she’ll take her customers to dinner in order to _______.A. see what kind of person they areB. experience the feeling of being servedC. shoe her generosity towards people inferior to herD.arouse their sympathy for people living a humble life(D)In 1784, five years before he became president of the United States, George Washington, 52, was nearly toothless. So he hired a dentist to transplant nine teeth into his jaw—having extracted them from the mouths of his slaves.That's a far different image from the cherry-tree-chopping George most people remember from their history books. But recently, many historianshave begun to focus on the roles slavery played in the lives of thefounding generation. They have been spurred in part by DNA evidence made available in 1998, which almost certainly proved Thomas Jefferson had fathered at least one child with his slave Sally Hemings. And only over the past 30 years have scholars examined history from the bottom up. Works of several historians reveal the moral compromises made by the nation's early leaders and the fragile nature of the country's infancy. More significantly, they argue that many of the Founding Fathers knew slavery was wrong—andyet most did little to fight it.More than anything, the historians say, the founders were hampered bythe culture of their time. While Washington and Jefferson privately expressed distaste for slavery, they also understood that it was part ofthe political and economic bedrock of the country they helped to create.For one thing, the South could not afford to part with its slaves. Owning slaves was "like having a large bank account," says Wiencek, authorof An Imperfect God: George Washington, His Slaves, and the Creation of America. 'The southern states would not have signed the Constitutionwithout protections for the "peculiar institution," including a clause that counted a slave as three fifths of a man for purposes of congressional representation.And the statesmen's political lives depended on slavery. The three-fifths formula handed Jefferson his narrow victory in the presidential election of 1800 by inflating the votes of the southern states in the Electoral College. Once in office, Jefferson extended slavery with the Louisiana Purchase in 1803; the new land was carved into 13 states,including three slave states.Still, Jefferson freed Hemings' children—though not Hemings herself or his approximately 150 other slaves. Washington, who had begun to believethat all men were created equal after observing the bravery of the black soldiers during the Revolutionary War, overcame the strong opposition of his relatives to grant his slaves their freedom in his will. Only a decade earlier, such an act would have required legislative approval in Virginia.86. In Paragraph 1,George Washington's dental surgery is mentionedto__________A．show the poor medical practice in the past.B．demonstrate the great cruelty of slavery in his days.C．stress the important role of slaves in the entire U.S. history. D．reveal an unknown aspect of his life and introduce the topic87.We may infer from the second paragraph that_____________.A. DNA technology has been widely applied to history research.B. In its early day. s the U. S. was confronted with delicate situations.C. historians deliberately made up some stories of Jefferson's life.D.Political compromises are easily found throughout the U. S. history.88. What do we learn about Thomas Jefferson?A. His political view changed his attitude towards slavery.B. His status as a father made him free the child slaves.C. His attitude towards slavery was complex.D. His affair with a slave ruined his reputation.89.Which of the following is TRUE according to the text?A. Some founding fathers benefited politically from slavery.B. Slaves in the old days did not have the right to vote.C. Slave owners usually had large savings accounts.D. Washington decided to free slaves due to moral considerations. Translation1.社会上，年轻⼈赶时髦，穿时尚⾐服是常有的事。

They are wrong. Everyone has imagination, but most of us, once we become adults, forget how to 47 it. Creativity isn’t always connected with great works of art or ideas. People at work and in their free time 48 think of creative ways to solve problems. Maybe you have a goal to achieve, a tricky question to answer or you just want to expand your mind! Here are three techniques to help you.Making connections. This technique involves taking 49 ideas and trying to find links between them. First, think about the problem you have to solve or the job you need to do. Then find an image, word, idea or object, for example, a candle. Write down all the ideas/words6with candles: light, fire, matches, wax, night, silence, etc. Think of as many as you can. The next stage is to relate the 51 to the job you have to do. So imagine you want to buy a friend an original 8 ; you could buy him tickets to match or take him out for the night.NO limits! Imagine that normal lim itations don’t exist. You have as much time /space78 / money, etc. as you want. Think about your goal and the new 52 . If your goal is to learn to ski, 53 , you can now practice skiing every day of your life (because you have the time and the money). Now 54 this to reality. Maybe you can practice skiing every day in December, or every Monday in January.Be someone else! Look at the situation from a 55 point of view. Good businessmen use this technique in trade, and so do writers. Fiction writers often imagine they are the characters in their books. They ask questions: What does this character want ？ Why can’t she get it？ What changes must she make to get what she wants ？ If your goal involves other people, put yourself in their 56 .

A. positions B. dreams C. images D. directionsⅣReading:16%(A)For many years, Hawaii has been a magic name to people who like to travel. People, both in Japan and in America, dream of seeing this beautiful island in the middle of the Pacific Ocean. Their dreams always include the sunset over the ocean. The sun drops like a ball of golden fire into the sea, and it drops .so quickly that you can almost see it move. The sun leaves behind a glow(霞光) that lights the skies and shines in the quiet water.People often have a quiet, peaceful time while walking along the beach. The first strangers to these islands centuries ago were who came from Tahiti in canoes(独木舟) .Now no matter where the people come from, they really want to see the original(原始的) beauty of Hawaii. They want to see the lovely beaches and the mountain called Diamond Head which is almost hidden by the tall hotels.57. The most magic thing on the beautiful islands is ______ .A. the tropical plantsB. a leisurely walk along the beachC. the sunset9D. the quiet water58.______ doesn’t belong to “the original beauty of Hawaii.A.White sand beaches .B. Waving palm trees.B.Tall hotels. D. The Diamond Head Mountain.59.The last paragraph suggests _____.A. the scenery nowadays is totally different from the original beauty.B. it is not quite easy to see the original beauty, because some of the scenery is almost hidden by tall hotels.C. it is easy to see the original beauty ,but only by taking jet planes.D. it is difficult to see the original beauty ,for things have completely changed in the last 25 years.60.The best topic of the passage is _____.A. Islands.B. A Magic Name.C. Travelling in Hawaii.D. Hawaii, the Dramatic Beauty.(B)Trees should only be pruned (修剪) when there is a good and clear reason for doing so and , the number of such reasons is small. Pruning involves the cutting away of overgrown and unwanted branches, and the inexperienced gardener can be encouraged by the thought that more damage results from doing it unnecessarily10than from leaving the tree to grow in its own way.First, pruning may be done to make sure that trees have desired shape or size. The object may be to get a tree of the right height, and at the same time to help the growth of small side branches, which will thicken its appearance or give it a special shape. Secondly, pruning may be done to make the tree healthier. You may cut out diseased or dead wood, or branches that are rubbing against each other and thus cause wounds. The health of a tree may be encouraged by removing branches that are blocking up the center and so preventing the free movement of air.One result of pruning is that an open wound is left on the tree and this provides an easy entry for disease , but it is a wound that will heal (愈合). Often there is a race between the healing and the disease as to whether the tree will live or die, so that there is a period when the tree is at risk. It should be the aim of every gardener to reduce that risk of death as far as possible. It is important to make the area, which has been pruned, smooth and clean, for healing will be slowed down by roughness. You should allow the cut surface to dry for a few hours and then paint it with one of the materials available from garden shops produced especially for this purpose. Pruning is usually done in winter , for then you can see the shape of the tree clearly without interference (妨碍) from the leaves and also it is very unlikely that the cuts you make will bleed. If this does happen, it is, of course, impossible to paint them properly .61.Pruning should be done to _____.A．make the tree grow taller.11B．improve the shape of the tree.C．get rid of the small branches .D．make the small branches thicker.62．Trees become unhealthy if the gardener__________.A．allows too many branches to grow in the middleB. does not protect them from the windC. forces them to grow too quickly.D．damages some of the small side branches63.Why is a special material painted on the tree?A．To make a wound smooth.B．To prevent disease entering a wound.C．to cover a rough surface.D．To help a wound to dry.64．What was the author’s purpose when writing this passage?A．To give practical instruction for pruning a tree.B．To give a general description of pruning.12C．To explain how trees develop disease.D．To discuss different methods of pruning.(C)Examinations have a longer history in China than in any other country, yet it is today an issue around in which controversy flourishes. At each stage of their school lives children are faced with exams: exams to enter junior middle school, senior middle school, vocational school, colleges and universities. As a result of having constantly to think of these hurdles facing them children find themselves under constant pressure, unable to take time off from studying exam-oriented subjects to relax with friends or to develop other interests. Within school the concentration on exam success leads to the neglect of courses which are not central to the examinations and a method of teaching and learning which emphasizes training the ability to do well in tests but neglects developing the ability to think creatively.Despite such criticisms the examination system still has its defenders. Without it, they argue, how can we test students’ abilities and evaluate the effectiveness of teachers and schools They believe that they provide the only objective way of selecting students and reduce the exercise of unfair back-door practices to gain advantage for children on the basis of influence or corruption. Examinations are also felt to offer the impetus to students to master their subject in a way in which they otherwise might not. "While too much anxiety can be a bad thing, a little anxiety can stimulate students to learn better than if left without any test to pass," says Li Jie, a leading advocate of the value of testing. "I can remember things now which give me great pleasure which I doubt I would have learned at the time if I had not13had to do so for the examinations.\65.Which of the following statements about emminations in China is correct?A.People can make money out of examination.B.Only students of today have to take examination.C.Students have to learn more about history than about any other subjects.D.People have different opinions concerning the value of examinations.66. What is a possible result if students pay too much attention to examinations？[A] Students neglect those exam-oriented subjects.[B] Students are unable to relax with friends or to develop other interests.[C] Teachers neglect the training of the students' ability to do well in tests.[D] Students only pay attention to the development of their ability to think creatively.67. Which of the following has NOT been mentioned as the advantage of examinations？[A] Examinations are the only objective way of selecting students.[B] Examinations are the only objective way to eliminate the problem of corruption.[C] Examinations can tell us that too much anxiety can be a bad thing.14[D] Examinations can better stimulate students to study.68 Which of the following is an acceptable summary of the organization of this passage？[A] Discussing a problem in education. [B] Refuting (反驳)a long held opinion.[C] Persuading people to believe an idea. [D] Presenting a controversial issue and arguments from both sides.(D)The next time you try for a high-ranking post, you could let your possible boss listen to a recommending phone call“made”by US President George W．Bush or British Prime Minister Tony Blair.Of course, neither of them could really do that for you－you would just ”borrow” their voices. AT&T labs will start selling speech software that, it says, is so good at reproducing the sounds of a human voice that it can recreate voices of long-dead famous people back to life.The software, which turns printed text into speech, makes it possible for a company to use recordings of a person's voice to say things that the person never actually said.Possible customers for the software, which is priced at the thousands of dollars, include telephone call centers, companies that make software that reads digital files aloud, makers of automated voices devices．The advances raise several15problems．Who, for example owns the rights to a famous person's voice? (Some experts even believe that new contracts will be drawn that include voice-licensing clauses.)And although scientists say the technology is not yet good enough to commit fraud(假冒), would the synthesized(合成的)voices at last be able to trick people into thinking that they were getting phone calls or digital audio recordings from people they knew?Even Mr. Fruchterman, one of AT&T lab's possible first customers, said he wondered what the new technology right bring. “Just like you can't trust a photograph any more,” he said, “You won't be able to trust a voice either.”69. With the help of the speech software, it is most possible ________.A. to improve a famous person's speechB. to say what you want in another's voiceC. to make a speech much more easilyD. to help you to find a better job70. If the speech software is widely used, ________.A. people would no longer believe each otherB. it would not be necessary to go for a speech by a famous person16C. no radio or TV broadcasters would be neededD. recording a voice alone would not be taken as a proof in the court71. According to the passage, you can infer that ________.A. the software will turn out to be an immediate success in the marketB. the government will forbid the sale of the software in the marketC. it's hard to decide whether software will enjoy popularityD. the software will soon prove to be nothing but rubbish(4) The passage mainly wants to ________.A. introduce a new softwareB. explain the advantage of a new inventionC. advertise a new kind of productD. describe the future market of a new productKEYS:17-21 BBDCB 22-26 CBCAC 27-31 DCCAC 32-36 ACBCA 37-41 DCCCB 42-46 DDBACKeys:1747-51 CBBAA 52-56 ADDCDKEYS:57-60 CCBDB 61-64 BBAC 65-68 DBCA 69-72 BCAB18。
