Model Test (7) Band TwoPart I Writing (30 minutes)Directions:For this part, you are allowed 30 minutes to write a short essay on the topic S tudents’Feeding Pets in Their Dormitories. You should write at least 120 words following the outline given in Chinese below:1.许多大学生在宿舍养宠物2.有些人反对这种做法3.我的看法Part II Reading Comprehension (Skimming and Scanning) (15 minutes) Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions on Answer sheet 2.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.Tomorrow’s CambridgeThe Values of CambridgeVisit Cambridge late in the 21st century and you will find it both the same and very different. The colleges will remain a huge strength, bringing together students and researchers from all disciplines and all parts of the world, and guaranteeing a human scale of values within a big university.Other core values will endure as well: excellence in teaching and research; a critical temperament (秉性)that emphasizes rigor and independence of mind; a stress on the interplay between disciplines, on small-group teaching and the centrality of social interaction of Cambridge will make alumni (校友)feel part of the University’s extended family for life.Above everything else will still rise the questioning, tough-minded hunger for learning, for pushing the boundaries of knowledge ever outwards, that has characterized this university from the first.The Faculty BuildingsPhysically, though, much needs to change if we are to have faculty buildings equal to these challenges. Not in the heart of the city: the colleges, the Backs, theriver and the commons and meadows that cluster around it. The profound sense of place that everyone values will at all costs be protected. But visit in fifty years and you’ll find what are now windswept hedgeless fields on the edge of Cambridge transformed into two new campuses: for the physical sciences and technology to the west, and for the biomedical sciences to the south.West Cambridge now has such momentum of its own that its innovative mix of university departments and charitable and commercial research centers could easily materialize even faster than we now imagine. Substantial resources are required but the outlook looks good.In contrast, our expansion plans to the south----a joint venture between the University, the Medical Research Council and Addenbrooke’s NHS Trust ---- are still at an early stage. The aim is a complementary biomedical campus around Addenbrooke’s Hospital with a university-business mix that will ensure Cambridge can compete scientifically at a world level.Looking forward decades, I see a whole corridor for biomedical research that will ultimately extend from Addenbrooke’s through Babraham to Hinxton, where other science parks in which the University is involved are already under development.To balance this natural boom in the sciences and technology, our key planning priority for the next ten years is the arts and humanities. On the Sidgwick site we don’t, of course, have the space we enjoy in west or south Cambridge so we need to be more creative. A new Theology faculty(神学院)is under construction at the moment, and we have preliminary plans for new buildings for English, Criminology and East Asian Studies. For English in particular, a world-class faculty obliged still to operate from a warren of rooms in a Victorian house, we’re about to embark on a major fundraising initiative.Other options will open up naturally in due course as new science developments free up hemmed-in city centre sites. Mathematics moves next year from Silver Street to a magnificent, purpose-built home on Clarkson Road, and we hope that Computer Science will be able to transfer to West Cambridge soon, with Materials Science, Earth Sciences, and elements of Engineering to follow in years to come. That should offer at least some of the growing room we need for the next century.In the new millennium Cambridge is quite determined to remain among the top half dozen universities in the world. You don’t have the wealth of Harvard say the doubters. Well, I respond, endowment is not a university and we’re certainly not about to throw in the towel just because Harvard’s endowment dwarfs that of every other university in the world.My own concern is not so much lack of resources as the limited presence of business in the Cambridge area. We’re very proud of our 1,200 high-tech start-ups; for the most part it’s the University that has brought them here. But the business baseis tiny compared with that around Boston or Stanford. That’s our problem: not competitor universities but the sheer scale of what surrounds them.You need a complete community; not just start-ups, but large and medium-sized companies too. All of them would benefit from the University’s intellectual expertise. It’s a two-way street, of course. Academics don’t just do what business tells them: they’re paid to do fundamental research that may not have immediate commercial applications, so success requires collaboration not coercion. Pooling business and intellectual expertise in this way benefits everyone.We do very much want to see big companies like Microsoft and BP here. Small companies can run away with ideas that big companies are too clumsy to exploit----tha t’s their strength. But basic technological advantages come from big players.The fact that our computer network is so advanced will also soon give us the opportunity to share our teaching expertise with local companies and even other universities; a dedicated centre for distance learning is already under discussion. We will increasingly use internet-based computer courses, to enhance our own teaching and also to reach students outside the University. That doesn’t mean computer terminals will displace people; students are always going to need advice and high-quality tuition on the spot. But it does mean we can refine our teaching courses over time and make them available in the manner of textbooks.Within the university itself, access is going to remain our key priority. We’re striving to demystify Cambridge and increase the proportion of state school students we take. We want to ensure that ethnic minority, overseas and disabled applicants are encouraged and supported. We want to secure women’s full participation in the University and increase their representation in top academic posts. We want to encourage alumni to take more interest in Cambridge so we can draw on their expertise and experience.And we want to keep winning the Boat Race.1. Massive-class teaching is one of the core values in Cambridge.2. Every student graduated from Cambridge will feel himself a part of Cambridge all his life.3. No changes of faculty buildings will be done in order to protect campusenvironment in Cambridge.4. Harvard endows the most among all the universities in the world.5. The arts and humanities will be put on the first place in the future development in Cambridge.6. A new building for English faculty will be built by a major fund raising.7. According to the passage, Cambridge will enlarge the rate of enrolling students.8. A plan is offered that there will be a complementary biomedical campus aroundAddenbrooke’s Hospital with a university-business to ________________.9. Tomorrow’s Cambridge will be the mixed place of _______________________.10. Computer terminals will never displace people because_____________________ ____________________________.Part III Listening Comprehension (35 minutes)Section A:Directions:In this section, you will hear 8 short conversations and 2 long conversations.

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.You may not use any of the words in the bank more than once.If you have dreamed of owning your own business, retirement can be the perfect opportunity to realize that dream.

Above all, you will believe in yourself and your ability toSection B:Directions: 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 write the corresponding letter on Answer Sheet.Passage OneQuestions 57 to 61 are based on the following passage.When they advise your kids to “get an education”if you want to raise your income, they tell you only half the truth. What they really mean is to get just enough education to provide manpower for your society, but not so much that you prove an embarrassment to your society.Get a high school diploma, at least. Without that, you are occupationally dead, unless your name happens to be George Bernard Shaw or Thomas Alva Edison and you can successfully drop out in trade school.Get a college degree, if possible. With a B.A., you are on the launching pad. But now you have to start to put on the brakes. If you go for a master’s degree, make sure it is an M.B.A., and only from a first-rate university. Beyond this, the famous law of diminishing returns begins to take effect.Do you know, for instance, that long-haul truck drivers earn more a year than full professors? Yes, the average 1977 salary for those truckers was 24 000 while the full professors managed to average just 23 930.A Ph. D. is the highest degree you can get, but except in a few specialized fields such as physics or chemistry, where the degree can quickly be turned to industrial or commercial purposes, you are fasting a dim future. There are more Ph. D.s unemployed or underemployed in this country than in any other part of the world by far.If you become a doctor of philosophy in English or history or anthropology or political science or language or worst of all-in philosophy, you run the risk of becoming over-educated for our national demands. Not for our needs, mind you, but for our demands.Thousands of Ph.D.s are selling shoes, driving cabs, waiting on tables and filling out fruitless applications month after month. And then maybe taking a job in some high school or back water college that pays much less than the janitor earns.You can equate the level of income with the level of education only so far. Far enough, that is, to make you useful to the gross national product, but not so far that nobody can turn much of a profit on you.57. According to the writer, what the society expects of educations is to turn outpeople who ________.A. will not be a shame to the educational systemB. will become loyal citizensC. can take career of themselvesD. can meet the demands of society as a source of manpower58. If you are as gifted as Bernard Shaw or Edison, ________.A. you can get a high school diploma without difficultyB. you will be successful in a grade schoolC. you can be professionally successful without a diplomaD. the least you should do is to get a diploma59. Ph.D.s are most likely to____________.A. have difficulties getting properly employedB. be employed in the fields of commerce or industryC. have to fill out application forms month after month for othersD. work in schools or colleges with low pay60. The nation is only interested in people_________.A. with diplomasB. specialized in physics and chemistryC. valuable to the gross national productD. both A and C61. According to the writer, a Ph.D. in English is _________.A. lucky to learn in their interested fieldB. hard to get an appropriate jobC. easy to earn more money than college professorsD. happy to fit for the demands of societyPassage TwoQuestions 62 to 66 are based on the following passage.NASA, the U.S. space agency, believes here’s a good chance that we’re not alone in the universe. Last fall, NASA began a new project called the High Resolution Microwave Survey (HRMS). Its aim: to find evidence of life in one of the billions of galaxies in the universe. The search for intelligent life on other planets isn’t new. It began almost 100 years ago. That’s whe n scientists built a huge transmitter to send radio waves into space. Scientists thought smart beings on other planets might pick up the signals.Scientists also have sent a message about humans and our solar system to a nearby constellation (星座). But because the constellation is 25,000 light years away, a return message wouldn’t reach Earth for 50,000 years! So don’t wait up for an answer.So far, no extraterrestrial (地球外的) beings that we know of have returned our “calls.” But according to Dr. Jill Tarter, an HRMS scientist, we haven’t exactly had our ears wide open. “Now, however,” says Dr. Tarter, “we’ve built the tools we need to listen well.” Last October, Dr. Tarter switched on the largest radio receiver in the world. It’s an enormous metal bowl st retching 1,000 feet across a valley in Puerto Rico.Meanwhile, another NASA scientist turned on a huge radio receiver in California’s Mojave Desert. NASA hopes these big dishes-and others around the world-will pick up radio signals from new world. Dr. Frank Drake has been searching for life in outer space for years. He explains the HRMS project this way: To listen to your radio, you move the tuner on the dial until the channels come in loud and clear: Now imagine radio receivers that scan our galaxy “listening” to 14 million channels every second. That’s what NASA’s radio receivers in Puerto Rico and California are doing.But that’s not all. Powerful computers hooked to the receivers examine every signal carefully. The computers try to match the signals to ones that scientists already recognize, such as human-made signals. If they can’t, Drake and Tarter check on them. “It could prove there is radio technology elsewhere in the universe,” says Dr. Tarter. “And that would mean we’re not alone.”62. NASA scientists started a new project in order to _________.A. discover life in other galaxiesB. send human beings into spaceC. find evidence of a new galaxyD. confirm the number of galaxies63. According to Dr. Jill Tarter, the reason why we haven’t received any returnmessages from outer space is that _________.A. our ears are not sharp enough to hear themB. our equipment hasn’t been good enoughC. it takes millions of years for them to reach usD. it takes quite a long time to send them64. Dr. Jill Tarter compares the large receiver to _________.A. the human earB. the universeC. a metal bowlD. a huge dish65. According to Dr. Frank Drake, NASA’s radio receivers in Puerto Rico andCalifornia are _________.A. trying to check on every channel carefullyB. moving the tuner on the dial for clear channelsC. scanning the universe for possible signalsD. picking up radio signals from new world66. The best title of this passage is _________.A. Signals from the SpaceB. The Invention of New Radio ReceiversC. The Intelligent Life in Outer SpaceD. NASA Listens for Space NeighborsPart V. Cloze (15 minutes)Directions: There are 20 blanks in the following passage. For each blank there are four choices marked A, B, C and D. You should choose the ONE that best fits into the passage. Then write the corresponding letter on the Answer Sheet.Some people have quit jobs that were __(67)__ or meaningless to them.

计算机二级模拟试题及答案计算机二级考试是许多大学生和职场人士提升自身计算机技能的重要途径。
以下为大家提供一套计算机二级模拟试题及答案,希望能对您的备考有所帮助。
一、选择题(每题 2 分,共 40 分)1、下列叙述中正确的是()A 顺序存储结构的存储一定是连续的,链式存储结构的存储空间不一定是连续的B 顺序存储结构只针对线性结构,链式存储结构只针对非线性结构C 顺序存储结构能存储有序表,链式存储结构不能存储有序表D 链式存储结构比顺序存储结构节省存储空间答案:A解释:顺序存储结构的存储一定是连续的,而链式存储结构的存储空间不一定是连续的,A 选项正确。
顺序存储结构和链式存储结构都可以用于线性结构和非线性结构,B 选项错误。
两种存储结构都可以存储有序表,C 选项错误。
链式存储结构由于需要存储指针,通常比顺序存储结构更耗费存储空间,D 选项错误。
2、设一棵二叉树中有 3 个叶子结点,有 8 个度为 1 的结点,则该二叉树中总的结点数为()A 12B 13C 15D 不能确定答案:B解释:根据二叉树的性质,度为 0 的叶子结点数总是比度为 2 的结点数多 1。
已知有 3 个叶子结点,所以度为 2 的结点数为 2。
总的结点数=度为 0 的叶子结点数+度为 1 的结点数+度为 2 的结点数= 3 + 8 + 2 = 13。
3、在深度为 5 的满二叉树中,叶子结点的个数为()A 32B 31C 16D 15答案:C解释:在满二叉树中,叶子结点都在最底层。
深度为k 的满二叉树,叶子结点个数为 2^(k 1) 。
所以深度为 5 的满二叉树,叶子结点个数为 2^(5 1) = 16 。
4、下列排序方法中,最坏情况下比较次数最少的是()A 冒泡排序B 简单选择排序C 直接插入排序D 堆排序答案:D解释:冒泡排序、简单选择排序和直接插入排序在最坏情况下的比较次数均为 n(n 1) / 2 ,而堆排序在最坏情况下的比较次数为O(nlog₂n) ,所以堆排序在最坏情况下比较次数最少。
