Some people argue that internships are crucial for students’ future career development, while others believe that students should spend their summer vacations relaxing. Personally, I firmly believe that students should indeed take part in summer internships for several reasons.Firstly, summer internships provide students with valuable opportunities to apply their knowledge and skills in a real-world work environment. In classrooms, students gain theoretical knowledge, but they often lack practical experience. Byparticipating in internships, they can bridge the gap between theory and practice, gaining hands-on experience that will be beneficial for their future careers.Secondly, summer internships allow students to explore their career choices and make informed decisions about their future paths. Many students enter university without a clear understanding of their career goals. Through internships, they get exposure to different industries and job roles, enabling them to better understand their own interests and talents. This self-discovery process helps them make more informed decisions about their future career paths.Furthermore, summer internships give students the opportunity to establish valuable connections with professionals in their fields of interest. These connections can provide mentorship, guidance, and potentially even job opportunities in the future. Building a professional network early on can help students jumpstart their careers and open doors to various opportunities.Lastly, participating in summer i nternships can enhance students’ personal and professional growth. Internships often require students to take on responsibilities, work in teams, and solve real-world problems. These experiences help develop crucial skills such as communication, leadership, and problem-solving, which are highly valued in the job market. Moreover, internships also expose students to different work cultures and perspectives, broadening their horizons and fostering their adaptability.In conclusion, I strongly believe that students should participate in summer internships. Internships provide valuable hands-on experience, help students explore career choices, establish professional connections, and foster personal and professional growth. By actively engaging in internships, students can prepare themselves for successful careers and gain a competitive edge in the job market.。

There is something provoking and interesting in this paradox, just because sword does not wear the stone as dripping water does.The ability to do something over and over again in a short time may imply its easin ess, but in a long run, a lifetime maybe, things turn out to be quite the opposite. Also, a s is often the case, one may have obtained all the tools and opportunities to achieve som ething, but in the end they still fail due to the will shortage.So how could we avoid the dilemma?

When the passage is read for the second time, you are required to fill in the blanks with the exact words you have just heard. Finally, when the passage is read for the third time, you should check what you have written.When you look up at the night sky, what do you see? There are other (26) heavenly bodies out there besides the moon and stars. One of the most (27) fascinating of these is a comet.Comets were formed around the same time the Earth was formed. They are (28) made up of ice and other frozen liquids and gases. (29) Now and then these “ dirty snowballs” begin to orbit the sun, just as the planets do.As a comet gets closer to the sun, some gases in it begin to unfreeze. They (30) combine with dust particles from the comet to form a huge cloud. As the comet gets even nearer to the sun,a solar wind blows the cloud behind the comet, thus forming its tail. The tail and the (31) generally fuzzy atmosphere around a comet are (32) characteristics that can help identify this (33) phenomenon in the night sky.In any given year, about a dozen known comets come close to the sun in their orbits. The average person can’ t see them all, of course. Usually there is only one or two a year bright enough to be seen with the (34) naked eye. Comet Hale-Bopp, discovered in 1995, was an unusually bright comet. Its orbit brought it (35) relatively close to the Earth, within 122 million miles of it. But Hale-Bopp came a long way on its earthly visit. It won’ t be back for another four thousand years or so.参考答案：26. heavenly27. Fascinating28. made up of29.

You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.Questions 47 to 56 are based on the following passage.Language is learned primarily through communication with other people. Research shows that the more communication children 47 at home the better developed their language skills will be. Children need to 48 well in order to learn well. This is especially important for the development of native language skills since the language is 49 reinforced by the child’s environment outside school.However, the 50 of communication is just as or more important than quantity alone. The language adults use helps children become aware of the many 51 aspects of objects and events around them. For example, during a shopping trip to the market or store, adults can develop children’s concepts by bringing their attention to the shapes, colors, sounds, textures, and size of objects and events around them. Parents can do this naturally through conversation without 52 teaching. In other words, conversation with children in 53 situations expands their minds and develops their thinking skills.In addition to conversing with children, adults can help prepare their children to succeed in school by encouraging them to take an 54 interest in books and in the print that surrounds them in the environment. The child’s first major 55 in school is learning to read. Children who come to school with knowledge that the print around them carries important meanings and with an interest in books and stories will usually 56 in learning to read rapidly.Section BDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 57 to 61 are based on the following passage.In the early 20th century, a horse named Clever Hans was believed capable of counting and other impressive mental tasks. After years of great performance, psychologists discovered that though Hans was certainly clever, he was not clever in the way everyone expected. The horse was cunningly (聪明地) picking up on tiny, unintentional bodily and facial cues given out not only by his trainer, but also by theaudience. Aware of the “Clever Hans”effect, Lisa Lit at the University of California, Davis, and her colleagues wondered whether the beliefs of professional dog handlers might similarly affect the outcomes of searchers for drugs and explosives. Remarkably, Dr. Lit found, they do.Dr. Lit asked 18 professional dog handlers and their dogs to complete brief searches. Before the searches, the handlers were informed that some of the search area might contain up to three target scents (气味), and also that in two cases those scents would be marked by pieces of red paper. What the handlers were not told was that none of the search areas contained the scents of either drugs or explosives. Any “detections”made by the teams thus had to be false.The findings reveal that of 144 searches, only 21 were clean (no alerts). All the others raised one alert or more. In total, the teams raised 225 alerts. While the sheer number of false alerts struck Dr. Lit as fascinating, it was where they took place that was of greatest interest.When handlers could see a red piece of paper, allegedly marking a location of interest, they were much more likely to say that their dogs signaled an alert. The human handlers were not only distracted on almost every occasion by the stimulus aimed at them, but also transmitted that distraction to their animals —who responded accordingly. To mix metaphors, the dogs were crying “wolf”at the unconscious signal of their handlers.How much that matters in the real world is unclear. But it might. If a handler, for example, unconsciously “profiled”people being sniffed (嗅) by a drug- or explosive-detecting dog at an airport, false positives could abound (大量存在). That is not only bad for innocent travelers, but might distract the team from catching the guilty.57. What did psychologists find out about Clever Hans?A) He was really good at counting. C) He merely responded to human signals.B) He was as clever as people claimed. D) He could understand human language.58. What did the dog handlers learn before the searches?A) There was actually no target scent in the search area.B) Each search area contained three target scents.C) Their dogs were expected to find the scents of red paper.D) Some target scents may be labeled with a special mark.59. According to Dr. Lit, the most significant about the experiment was .A) the way the dogs raised alerts C) the average time of the searchesB) the location of the false alerts D) the number of the false alerts60. What can be concluded from the experiment?A) Dogs may act in response to their handlers’bodily signals.B) The cooperation between dogs and their handlers is key to success.C) Well-trained dogs can better understand their handlers’signals.D) Dog handlers are more likely to be distracted than their dogs.61. How does the author see Dr. Lit’s findings?A) They may not be useful in real situations.B) They should raise our concern in real life.C) They will be widely applied in the near future.D) They should be backed up by further evidence.Passage TwoQuestions 62 to 66 are based on the following passage.Being able to multitask is hailed by most people as a welcome skill, but not according to a recent study which claims that young people between the ages of eight and eighteen of the so-called Generation M are spending a considerable amount of their time in fruitless efforts as they multitask. It argues that, in fact, these young people are frittering (浪费) away as much as half of their time as they would if they performed the very same tasks one after the other.Some young people are using an ever larger number of electronic devices as they study. At the same time they are working, young adults are also surfing on the Internet, or sending out emails to their friends, and/or answering the telephone and listening to music on their iPods. As some new device comes along, it is also added to the list rather than replacing one of the existing devices.Other research has indicated that this multitasking is even affecting the way families themselves function as young people are too wrapped up in their own isolated worlds to interact with the other people around them. They can no longer greet family members when they enter the house nor can they eat at the family table.All this electronic wizardry (魔力) is supposedly also seriously affecting young people’s performance at university and in the workplace. When asked about their opinions of the impact of modern gadgets (小装置) on their performance of tasks, the great majority of young people gave a favorable response.The response from the academic and business worlds was not quite as positive. The former feel that multitasking with electronic gadgets by children affects later development of study skills, resulting in a decline in the quality of writing, for example, because of the lack of concentration on task completion. They feel that many undergraduates now urgently need remedial (补救的) help with study skills. Similarly, employers feel that young people entering the workforce need to be taught all over again.While all this may be true, it must be borne in mind that more and more is expected of young people nowadays; in fact, too much. Praise rather than criticism is due in respect of the way today’s youth are able to cope despite what the older generation throw at them.62. What do we learn about the multitasking Generation M from a recent study?A) They are highly praised for being efficient.B) They put more energy on important tasks.C) They don’t save much time as supposed.D) They need to improve their analytical skills.63. With the introduction of new gadgets, what happens to the Generation M’s present e-devices?A) They are put aside temporarily. C) They give way to the latest gadgets.B) They are either sold or traded. D) They become part of their collection.64. A research revealed that multitasking makes the Generation M ________.A) distant to their family C) impolite and ungratefulB) selfish and possessive D) feel lonely and pitiful65. The academics feel that many undergraduates badly need to ________.A) adjust their social attitudes C) improve their study skillsB) seek psychological assistance D) take more business courses66. What does the author suggest the older generation do in dealing with the multitasking youth?A) Heighten their expectations on the youth.B) Try to be supportive and understanding.C) Encourage the youth to stick to their old habits.D) Change the way the youth use the gadgets.“成千上万人疯狂下载。

The answers lie in the way Americans live today. During the first few decades of the twentieth century, canned and other convenience foods freed the family cook from full-time duty at the kitchen range.Then, in the 1940s, work in the wartime defense plants took more women out of the home that ever before, setting the pattern of the working wife and mother. Unless family members pitch in with food preparation, women are not fully liberated from that chore.It's easier to pick up a bucket of friedchicken on the way home from work or take the family out for pizzas or burgers than to start opening cans or heating up frozen dinners after a long, hard day. Also nowadays, the rising divorce rate means that there are more single working parents with children to feed. And many young adults and elderly people, as well as unmarried and divorced mature people, live alone rather than as a part of a family unit and don't want to bother cooking for one. Fast food is appealing because it is fast, it doesn't require any dressing up, it offers a "fun" break in the daily routine, and the outlay of money seems small. It can be eaten in the car-sometimes picked up at a drive-in window without even getting out-or on the run. Even if it is brought home to eat, there will never be any dirty dishes to wash because of the handy disposable wrappings. Children, especially, love fast food because it's finger food, no struggling with knives and forks, no annoying instructions from adults about table manners.1. Americans enjoy fast food mainly because ________.[A] it can be eaten in the car[B] it is much more tasty than home-made food[C] one only uses his fingers while eating it[D] it is time-saving and convenient2. It can be inferred that children ________.[A] want to have freedom at table[B] wash dishes after each meal[C] are not good at using forks and knives while eating[D] take eating time as a fun break3. Many Americans are eating out and not cooking at home nowadays because ________.[A] they want to make a change after eating the same food for years at home[B] the food made outside home tastes better than food cooked at home[C] many of them live alone or don't like taking trouble to cook[D] American women refuse to cook athome due to women's liberation movement4. According to the text, a drive-in window isa ________.[A] car window from which you can see the driver[B] window in the restaurant from which you get your meal in the car[C] place where you check the mechanic condition of your car[D] entrance where you return the used plates after eating5.

By the end of September, there will be InfraGard chapters in all 50 states, Calloway said. With advice from the FBI, each local chapter will be run by a board of directors that includes members of private industry, the academic community and public agencies. Bands, utilities, and other businesses and government agencies will use a secure Web site to share information about attempts to hack into their computer networks. Members can join the system free. A key feature of the system is a two-pronged method of reporting attacks.A "sanitized" description of a hackingattempt or other incident-one that doesn't reveal the name or information about the victim-can be shared with the other members to spot trends. Then a more detailed description also can be sent to the FBI's computer crimes unit to interfere if there are grounds for an investigation. Cyber crime has jumped in recent years across the nation, particularly in hotbeds of financial commerce and technology like Charlotte. "Ten years ago, all you needed to protect yourself was a safe, a fence and security officers," said Chris Swecker, who is in charge of the FBI's Charlotte office. "Now any business with a modem is subject to attack." FBI agents investigate computer hacking that disrupted popular Web sites including Amazon. com, CNN and Yahoo!several North Carolina victims have been identified this year. The investigation has also identified computer systems in North Carolina used by hackers to commit such attacks. Prosecutions of hackers have been hampered bythe reluctance of companies to report security intrusions for fear of bad publicity and lost business. Meanwhile, too many corporations have made it too easy for criminals by sacrificing security for speed and accessibility. Jack Wiles, who will lead the local InfraGard chapter's board, said a recent report estimated 97 percent of all cyber crime goes undetected. Wiles, a computer security expert, has a firewall on his personal computer to prevent hackers from getting into his files. "I get at least one report a day that somebody was trying to get into my computer," he said, "the Net is a wonderful place, but it's also a dangerous one."1. From the first paragraph, we know ________.[A] InfraGard is a protective measure against cyber crime[B] InfraGard is a measure of cooperation and collaboration[C] there will be 50 InfraGard chapters in all states[D] private business and the government are now committing cyber crime2. Each local chapter of InfraGard will be run by the following EXCEPT ________.[A] academic communities[B] public agencies[C] FBI[D] private industry3. By saying "too many corporations...speed and accessibility" (Lines 3～4, Para. 3), the author means ________.[A] too many corporations take no notice of the security problem of computers[B] criminals are sacrificing security for speed and accessibility[C] it's very easy to sacrifice security for speed and accessibility[D] many companies suffer from computer hacking because they value speed and accessibility more than security4. All the following are reasons for the rise in cyber crime EXCEPT ________.[A] victims won't report intrusions by hackers[B] victims have no firewalls[C] the use of modem is increasing[D] companies don't pay enough attention to security5.

Many countries have built canals near the coast, and parallel1 the coast. Even in the twentieth century, goods can be moved more cheaply by boat than by any other2 of transport. These 3 make it possible for boats to travel 4 ports along the coast without being 5 to the dangers of the open. Some canals, such as the Suez and the Panama, save ships weeks of time by making their6 a thousand miles shorter. Other canals permit boats to reach cities that are not 7 on the coast; still other canals8 lands where there is too much water, help to 9 fields where there is not enough water, and 10 water power for factories and mills. The size of a canal11 on the kind of boats going through it. The canal must be wide enough to permit two of the largestboats using it to 12 each other easily. It must be deep enough to leave about two feet of water13 the keel of the largest boat using the canal. When the planet Mars was first 14 through a telescope, people saw that the round disk of the planet was crises-crossed by a15 of strange blue-green lines. These were called "canals"16 they looked the same as canals on earth 17 are viewed from an airplane. However, scientists are now 18 that the Martian phenomena are really not canals. The photographs 19 from space-ships have helped us to 20 the truth about the Martian "canals".1. [A] off [B] with [C] to [D] by2. [A] way [B] means [C] method [D] approach3.

For questions 1-7, markY (for YES) if the statement agrees with the information given in the passage;N (for NO) if the statement contradicts the information given in the passage;NG (for NOT GIVEN) if the information is not given in the passage.For questions 8-10, complete the sentences with the information given in the passage.To Save Trees, Fighting One Alien Insect with OthersRusty rhea sighs wistfully as he talks about the beauty and peace of standing amid agrove (小树林) of deep green hemlocks in Appalachia, some of them up to 160 feet (50 meters) tall and more than 500 years old."This is a very special tree," said Rhea, an entomologist for the U.S. Forest Service's Forest Health Protection program in Asheville, North Carolina, "I was brought up here, and I don't want to see another species go by the wayside."The evergreen trees, a hallmark of southern Appalachia's national parks, are under attack by an invasive inse4ct barely visible to the eye but potent enough to fell the giants of the eastern United States' old-growth forests.Already the tiny bug from Japan, known as the hemlock woolly adelgid (HWA), has killed upward of 95 percent of the hemlocks in Virginia's Shenandoah National Park. Now they are making their way through the half-million-plus-acre (200,000-plus-hectare) Great Smoky Mountains National Park in North Carolina and Tennessee.The hemlocks shade streams, keepingwater temperatures just right for brook trout (鲑鱼) and other fish. They also house birds such as the black-throated green warbler, solitary vireo, and northern goshawk, all three of which mainly shelter in stands of hemlock trees.Because of the insect's broad impact on the entire ecosystem of southern Appalachia, HWA stands to cause wider damage than the American chestnut blight (枯萎病)of the early 1900s. That fungus from Europe killed off the once dominant chestnut trees from the northeast United States to the southern Appalachian Mountains.In addition, a species related to HWA, the balsam woolly adelgid, has already killed about 90 percent of the mature Fraser fir trees in the Smokies.Acting QuicklyHWA arrived in the U.S. Pacific Northwest via nursery plants from Japan in 1924. By 1951 the tiny invader had been foundin Virginia. Since then the insect has spread to more than 15 U.S. states.The key to killing the HWA is to catch it early and act quickly. It's already well established in the Great Smoky Mountains, where Rhea and others are trying to stem the spread of the bugs.HWA multiply quickly: All of the insects are females that reproduce asexually (无性地), laying several hundred eggs a year. When they get to the nymph, or crawler, stage, they are dormant from about June until October, after which they emerge and establish themselves on trees.Winds and birds and other animals spread the crawlers through the forest.HWA crawlers feed on the new growth of hemlocks by piercing the twigs that hold the branches, sucking the sap, and injecting toxic saliva. The needles turn from a deep green to a grayish green and eventually die, depriving the tree of nutrition from photosynthesis.An infected tree usually dies within five years of initial attack. Infection is signaled by either a white, cottonlike material that appears along a tree's twigs or by the "baldness" of a tree's upper branches.Plans of AttackIn the Pacific Northwest the hemlocks seem to be tolerant of the creatures' feeding, and in the cold northeast, winters seem to keep them at bay. But in the warm southeast, with weather approximating that of the insects' native Asian homes, they thrive.Chemical sprays-such as insecticidal soaps and horticultural oils as well as trunk or soil injections-have helped to kill some of the HWA infestations.But spraying must be repeated every six months, and injections are expensive and last only two years at most. These methods can't be used conveniently or safely in remote areas or near the streams where hemlocks grow thickly.Long term, the best way to control thepests appears to be releasing other insects that feed exclusively on HWA. Scientists have studied HWA in Japan and China and identified three such species. One of them, the Sasajiscymnus tsugae (St) beetle, was released in areas of Great Smoky Mountains National Park in 2002.Studying what controls a species in its native habitat-including climate, predators, and host resistance-provided clues about which insects to use against HWA, said Kristine Johnson. Based in Gatlinburg, Tennessee, Johnson is a supervisory forester for Great Smoky Mountains National Park."Biological control is the only long-term hope to save the trees in the backcountry (穷乡僻壤)," she said. "We have 800 square miles (2,100 square kilometers) of contiguous wilderness. We value the native forest, and it's entirely worth defending."Risky BusinessReleasing one species of non-native bug to kill another could be risky business, potentiallycreating another type of infestation. But scientists first quarantined and studied the HWA-killer insects.They believe the St beetles are the best answer to the HWA problem and that they won't cause side damage. This tiny black female beetle, the size of a poppy seed, is already spreading in the Great Smoky Mountains.But the beetle and other HWA-killer insects are seasonal, so it will take several different ones operating year-round to keep HWA in check, Rhea said. He doesn't believe HWA will be completely eradicated (根除) but will instead be kept in balance by the predator insects. "We're trying to insert a balance in a system that's out of balance," he said.Each St beetle can lay 200 to 300 eggs, said Ernest Bernard, professor of entomology at the University of Tennessee in Knoxville.Bernard's laboratory is one of several that are breeding the beetles."Each beetle eats hundreds of babyadelgids a year," he said. And about 120,000 of the beetles have been released in the past couple years in the Smokies, but it is still too early to measure their impact.One good sign, Bernard said, is that some beetle larvae (幼虫) have been found in areas where they were not released, indicating that the HWA killers may be reproducing and spreading.1. The passage gives a general description of an invasive insect, HWA.2. Hemlock is a hallmark of southern Appalachia's national parks.3. The invasive insect, known as the hemlock woolly adelgid (HWA), is from Japan.4. The key to killing the HWA is to catch it early and act quickly.5. An infected tree usually dies immediately.6. The Hemlock in the U.S. will be saved from HWA soon.7. The long term, best way to control the pests HWA is spraying.8. Since 1951 the HWA has spread to more than________.9. Releasing one species of non-native bug to kill another could create________.10. It will take several different insects operating year-round to________.1小题>【参考答案】：Y2小题>【参考答案】：Y3小题>【参考答案】：N4小题>【参考答案】：N5小题>【参考答案】：Y6小题>【参考答案】：Y7小题>【参考答案】：NG8小题>【参考答案】：15 U.S. states9小题>【参考答案】：another type of infestation10小题>【参考答案】：keep HWA in check五、翻译第6题：It is time the whole society began to take action to ________________________(使我们的环境免于毁灭).【参考答案】：save our environment from destruction第7题：If we had set out earlier, ________________________(我们就不会在雨中行走).【参考答案】：we wouldn’t have walked in the rain第8题：When this semester is over, ________________________ (我就能抽空读这部小说了).【参考答案】：I should be able to get around to reading this novel第9题：________________________ (在我设计出这个问题的解决方案后)，I’ll submit a report to the committee.【参考答案】：After I work out a solution to the problem第10题：________________________ (我已得出结论)that it would be unwise to accept his proposal.【参考答案】：I have come to the conclusion六、写作题第11题：Directions: For this part, you are allowed 30 minutes to write a composition on the topic: Online Education. You should write at least 120 words following the outline given below in Chinese:1. 目前网络教育形成热潮2. 我认为形成这股热潮的原因是……3. 我对网络教育的评价Online Education【参考答案】：Online EducationBeing online is no longer something strange in our life.To some degree, it has become part of our daily life. We can do a lot of things online, such as searching for information and communicating with friends far and near. But recently another helpful online activity has become very "in". That is online education.Why could online education be so popular within such a short period of time? Among all the reasons, the quick development of the internet should be the essential one, which makes our dreams of attending class in the distance possible. Another underlying reason is the quick development of both society and technology. Today, modern science and technology are developing at lightening speed. To catch up with the development we all feel an urgent and strong desire to study. However, due to the great pace of modern society, many people are too busy to study full time at school. Online education just comes to their aid.Personally, I appreciate this new form of education. It’s indeed a helpful complement tothe traditional education system. It can provide different learners with more flexible and versatile ways of learning. Most of all, with online education, we can absorb the latest knowledge while working.。

Part I Writing1.【题干】Directions： For this part, you are allowed 30 minutes to write an essay commenting on the saying "Learning is a daily experience and a lifetime mission." You can cite examples to illustrate the importance of lifelong learning. You should write at least 120 words but no more than 180 words.【答案】Undoubtedly, learning is a daily experience and lifetime mission. For instance, Madam Curie, who conducted pioneering research on radioactivity and became the first woman to win a Nobel Prize, was known for her persistence in learning.Several reasons, both social and individual, could account for the importance of constant learning. Firstly, in an age of ruthless and relentless competition, only by learning constantly can we bring our potential and ability into full play and catch up with the times. Secondly, learning does not only help us acquire knowledge, but also enriches our lives and broadens our horizons. Thirdly, science and technology change with each passing day. Without constant learning, it would be impossible for us to update our knowledge.Accordingly, it is constant learning that really matters in achieving success in modern society. In my humble opinion, it is high time that parents and teachers made joint efforts to encourage children to read more books instead of playing computer games all day.Part II Listening ComprehensionSection A2.【题干】Question 1【答案】B3.【题干】Question 2【答案】A4.【题干】Question 3【答案】C5.【题干】Question 4【答案】D6.【题干】Question 5【答案】B7.【题干】Question 6【答案】A8.【题干】Question 7【答案】D9.【题干】Question 810.【题干】Questions 9 to 12 are based on the conversation you have just heard.Question 9【答案】B11.【题干】Question 10【答案】C12.【题干】Question 11【答案】A13.【题干】Questions 12 to 15 are based on the conversation you have just heard.Question 12【答案】C14.【题干】Question 13【答案】B15.【题干】Question 14【答案】D16.【题干】Question 15【答案】CSection B17.【题干】Passage OneQuestion 1618.【题干】Question 17【答案】A19.【题干】Question 18【答案】D20.【题干】Passage Two Question 19【答案】B21.【题干】Question 20【答案】D22.【题干】Question 21【答案】C23.【题干】Question 22【答案】A24.【题干】Passage Three Question 23【答案】B25.【题干】Question 24【答案】B26.【题干】Question 25【答案】A27.【题干】_____【答案】heavenly28.【题干】_____【答案】fascinating 29.【题干】_____【答案】made up of30.【题干】_____【答案】Now and then 31.【题干】_____【答案】combine with 32.【题干】_____【答案】generally33.【题干】_____【答案】characteristics 34.【题干】_____【答案】phenomenon35.【题干】_____【答案】naked36.【题干】_____【答案】relatively37.【题干】_____38.【题干】_____【答案】G39.【题干】_____【答案】O40.【题干】_____【答案】K41.【题干】_____【答案】B42.【题干】_____【答案】I43.【题干】_____【答案】F44.【题干】_____【答案】M45.【题干】_____【答案】A46.【题干】_____【答案】D47.【题干】It will not be difficult to make learning a source of joy if educators change their way of thinking.48.【题干】What distinguishes children from adults is their strong ability to derive joy from what they are doing.【答案】D49.【题干】Children in America are being treated with shocking cruelty.【答案】A50.【题干】It is human nature to seek joy in life.【答案】F51.【题干】Grown-ups are likely to think that learning to children is what medicine is to patients.【答案】K52.【题干】Bad school conditions make it all the more important to turn learning into a joyful experience.【答案】L53.【题干】Adults do not consider children's feelings when it comes to education.【答案】C54.【题干】Administrators seem to believe that only hard work will lead children to their educational goals.【答案】I55.【题干】In the so-called "effective" schools, children are taught self-control under a set of strict rules.56.【题干】To make learning effective, educators have to ensure that children want to learn.【答案】J57.【题干】What does the author think of time displayed everywhere?【答案】C58.【题干】How do people usually go about their work according to the author?【答案】A59.【题干】What did Tamar Avnet and Anne-Laure Sellier find in their experiments about clock-timers?【答案】D60.【题干】What do the researchers say about today's business culture?【答案】B61.【题干】What do the researchers suggest?【答案】D62.【题干】What does the well-known columnist's remark about Martha Stewart suggest?【答案】A63.【题干】What do we learn from the second paragraph about many criminals in America?64.【题干】What are the consequences for many Americans with a criminal record?【答案】C65.【题干】What does the author think of the post-conviction laws and rules?【答案】D66.【题干】What is the author's main purpose in writing the passage?【答案】B67.【题干】云南省的丽江古镇是中国的旅游目的地之一。
