Choose one best answer and blacken the corresponding letter on Answer Sheet.Debate is a valuable way to practise communicating. It can also bring long-lasting rewards, especially for people working with Western businesses. The main activity of debate is presenting one's opinion and supporting it with evidence, such as statistics or facts. It is a way of persuasive communication.Charles Lebeau helped create the "Discover Debate" method. He says debate is important to understanding how people communicate in Western business. Successful debaters learn how togive their opinion, reasons and support. "What we are trying to do is to develop a kind of thinking or approach to discussion and how to interact (交流) with someone else's opinion, rather than brush their opinion aside."Debate skills are also important in selling a product, he says. In that situation, the judges are the customers. "So on Monday, for example, one company may come in and present their case to the customer and they'll make as strong a case as they can. On Tuesday, the next day, another company will come in and present their case to the customer. Usually the party that can present the strongest case wins."Debate also strengthens critical thinking. In other words, it helps students learn to ask questions and try to understand someone's reasons and evidence.Mr. Lebeau points out that successful debaters learn to listen carefully to what other people are saying. Then, they look for the weak points in someone else's opinion or argument. He says debate teaches a systematic way of questioning.Successful debaters also learn to think from someone else's point of view. Mr. Lebeau says debate can help broaden the mind. "There's an expression in English: don't criticize another person before you have walked in their shoes. I think the wonderful thing about debate is, it puts us in another person's shoes."第36题According to Paragraph 1, what is the purpose of debate?A.To bring long-lasting material rewards.B.To present evidence such as statistics and facts.C.To respond to questions in a systematic way.D.To persuade people to accept your opinions.第37题Why is debate important?A.It helps people understand others better.B.It allows people to present their opinions.C.It develops one's thinking and communicative competence.D.It gives one the opportunity to brush others' opinion aside.第38题What does the underlined word "case" in Paragraph 3 refer to?A.Container.B.Evidence.C.Problem.D.Product.第39题What can debaters benefit from "walking in another person's shoes"?A.Becoming more broad-minded.B.Developing critical thinking.C.Finding others' weak points.D.Trying out others' methods.上一题下一题(40~43/共20题)Part ⅢReading ComprehensionDirections:There are some reading passages in this part. Each passage is followed by some questions. For each question there are four suggested answers marked [A]、[B]、[C] and [D]. Choose one best answer and blacken the corresponding letter on Answer Sheet.We all love a hero, and rescue dogs are some of the biggest heroes of all. You will often find them going above and beyond duty to save someone, risking—and at times losing—their lives in the process.Rescue dogs are generally found in the Sporting and Hunting Groups, or from the traditional Herding Group. These types include the Bloodhound, Labrador Retriever, Newfoundland, German Shepherd, Golden Retriever, and Belgian Malinois—all of which are chosen for search-and-rescue duty because of their amazing physical strength, loyalty, and their tendency for mental stability.These types also have a keen sense of hearing and smell—to better locate lost individuals—and are often able to access hard-to-reach areas. As highly trained animals, they serve in many different fields, including specialist Search, snow slide rescue, dead body location, and tracking.To overcome obstacles and succeed when performing the demanding duties of a search-and-rescue worker, a dog must display certain qualities. In addition to intelligence and strength, the dog must be swift, confident, easily trainable, adaptable, and have a high level of stamina (耐力) and endurance. A strong sense of group cooperation and an ability to engage in friendly play during "down" time is also required of search-and-rescue dogs.A rescue dog goes through many, many hours of intensive training to be fit for duty. Training is not for the faint-hearted. Certification training can take from two to three years, working three to four hours a day, three to six days a week, often in group, team-oriented sessions.Each search-and-rescue field requires different types of training. Rescue training, for instance, includes "air scenting"—where dogs are trained to smell the air for the victim's scent (气味) and then follow the scent to the person. This ability is crucial to finding victims trapped under collapsed buildings and snow slide.第40题Rescue dogs are chosen probably because ______.A.they are loyalB.they are braveC.they have amazing appearancesD.they have good eyesight第41题What does "faint-hearted" in Paragraph 5 mean?A.Courageous.B.Cowardly.C.Energetic.D.Slow.第42题Which ability is most important for dogs to rescue people trapped in snow?A.Sharp hearing.B.Swift movement.C.Extraordinary smelling.D.A strong memory.What is the passage mainly about?A.Selection process of rescue dogs.B.Qualities and training of rescue dogs.C.Risks rescue dogs are faced with.D.Types of tasks rescue dogs can perform.上一题下一题(44~47/共20题)Part ⅢReading ComprehensionDirections:There are some reading passages in this part. Each passage is followed by some questions. For each question there are four suggested answers marked [A]、[B]、[C] and [D]. Choose one best answer and blacken the corresponding letter on Answer Sheet.Eating an apple a day doesn't keep the doctor away, but it does reduce the amount of trips you make to the drug store per year. That's according to a new study that investigates whether there's any truth in the old saying.A team of researchers led by Dr Matthew Davis, of the University of Michigan School of Nursing, asked 8,399 participants to answer survey questions about diet and health. A total of 753 were apple eaters, consuming at least 149g of raw apple per day. The remaining 7,646 were classed as non-apple eaters. When both groups answered questions on trips to the doctor and trips to the drug store per year, the apple eaters were found to be 27% less likely to visit the druggist for drugs.Trips to the doctor were not significantly affected by apple consumption, though. "Evidence does not support that an apple a day keeps the doctor away. However, the small number of US adults who eat an apple a day does appear to use fewer prescription medications," the study concludes.Apple eaters were also found to be less likely to smoke and be more likely to have a higher educational attainment than non-apple eaters. While apples do not compete with oranges, they do contain some immune (免疫的) system-increasing vitamin C, which may be why apple-eaters visit the druggist less. With over 8mg of vitamin C per medium-sized fruit, an apple can provide roughly 14% your daily recommended intake.Previous studies have also linked apple consumption to a lower risk of Type 2 diabetes (二型糖尿病), improved lung function and a lower risk of colon (结肠) cancer.第44题How many non-apple eaters answered survey questions in the research?A.149.B.7,646.C.753.D.8,399.第45题What is the conclusion of the study?A.Apple consumption has greatly reduced US adults' trips to the doctor.B.An apple a day does keep the doctor away.C.Apples are far more nutritious than oranges.D.A small number of US adult apple eaters tend to take less medicine.What can we learn from the passage?A.Apples are better than oranges.B.Apples do have some vitamin C to increase the immune system.C.Apples can help cure certain diseases.D.Apples can provide people with sufficient daily intake of energy.第47题What can be described as the writing style of this passage?A.Objective.B.Creative.C.Subjective.D.Persuasive.上一题下一题(48~51/共20题)Part ⅢReading ComprehensionDirections:There are some reading passages in this part. Each passage is followed by some questions. For each question there are four suggested answers marked [A]、[B]、[C] and [D]. Choose one best answer and blacken the corresponding letter on Answer Sheet.Sometimes I scratch my head when I read about the government's efforts to improve schools: new standards and tests to be applied, strict teacher evaluations, and threats of school closures and job losses. They frighten the school employees, not to mention the students. Instead of making people unable to solve problems or try new ideas—which is what fear does to us—research on school reform strongly suggests that policy-makers should encourage school leaders to take a more humane approach. In their study on the reform efforts of twelve Chicago public schools, Bryk and Schneider found that enabling positive social relationships between the adults was the key to successful school improvement and that trust was at the heart of those relationships.Trust in schools comes down to one thing: psychological safety or safety to speak one's mind, to discuss with openness and honesty what is and isn't working, to make collective decisions.Yet this kind of safety doesn't come easily to schools. According to Bryk and Schneider, the adults in school rely on each other to do their jobs correctly and with integrity (正直). The challenge is that our expectations are very diverse based on our unique backgrounds.At one school where I taught, each teacher had different expectations about how much extra effort teachers should put into their work—a big difference between the teachers who left after the last bell and those who worked into the evening. And when expectations are unconscious or unspoken, it becomes impossible for others to live up to them.We also make assumptions about the intentions behind a person's behavior. As we all know, assumptions are often wrong. For example, parents and teachers may think the principal made a particular decision based on his career advancement rather than what's best for the students. If we don't feel psychologically safe to question our assumptions and expectations, trust flies out the window and our relationships suffer.第48题According to Paragraph 1, why does the author scratch his head?A.Because he doesn't know what to do once schools are closed.B.Because he is not sure about the practicability of those new tests.C.Because he is concerned that many teachers will lose their jobs.D.Because he is not in favor of the government's reform efforts.第49题According to Bryk and Schneider, what was most important for successful school improvement?A.New standards and tests in schools.B.Positive social relationships.C.Strict teacher and student evaluations.D.Assistance of the government.第50题What is meant by trust in school?A.Freedom to express one's views.B.Extra effort teachers put into their work.C.Independence of the teachers in schools.D.Unconscious and unspoken expectations.第51题What does the author say about the assumptions made about the intentions behind a person's behavior?A.They should be trusted.B.They are often bold.C.They are often incorrect.D.They should be encouraged.上一题下一题(52~55/共20题)Part ⅢReading ComprehensionDirections:There are some reading passages in this part. Each passage is followed by some questions. For each question there are four suggested answers marked [A]、[B]、[C] and [D]. Choose one best answer and blacken the corresponding letter on Answer Sheet.An interesting project called Blue Zones is recording the lifestyle secrets of the communities with the highest concentrations of centenarians in the world.The people in the five regions in Europe, Latin America, Asia and the US that live to be 100 have a lot going for them. Genes probably play a small role, but these folks also have strong social ties, tightly-knit families and lots of opportunities to exercise.As we were examining the dietary secrets of the Blue Zones, as described in author Dan Buettner's latest book, The Blue Zones Solution, we were struck by how essential tea drinking is in these regions. In fact, Buettner's Blue Zones Beverage Rule—a kind of guideline summarized from his 15 or so years of studying these places—is: "Drink coffee for breakfast, tea in the afternoon, wine at 5 p.m."Science has plenty to say about the healthful virtues of green tea. Researchers are most enthusiastic about the components in green tea, as well as foods like cocoa. Why might they help so many Okinawans in Japan break 100? Some components in green tea can lower the risk of stroke, heart disease and several cancers. One review study also found that drinking green tea can slightly improve metabolism (新陈代谢).If you find yourself on the island of Ikaria, the Greek Blue Zone in the middle of the Aegean,you won't be offered any tea made with tea leaves. Instead, Ikarians typically make their daily cup of tea with just one fresh herb that they have picked themselves that day—either rosemary, wild sage, oregano, marjoram, mint or dandelion, all plants that may have anti-inflammatory (消炎的) properties, which may help lower blood pressure. This could explain Ikaria's very low dementia (痴呆) rate, since high blood pressure is a risk factor for the disease.第52题What does the underlined word "centenarians" in Paragraph 1 refer to?A.People who have secret lifestyles.B.People who enjoy physical exercise.C.People who are one hundred years old or older.D.People who carry, the gene for being slim.第53题According to Paragraph 3, what is the recommended time for tea drinking?A.In the morning.B.Any time of a day.C.In the early evening.D.In the afternoon.第54题What may the tea Ikarians drink daily help?A.To improve metabolism.B.To lower blood pressure.C.To lower life stress.D.To improve social relationships.第55题What might be the best title of the passage?A.Tea-Drinking TipsB.Lifestyle Secrets of IkariansC.Tea-Drinking Ceremony in OkinawaD.Blue Zones Solutions上一题下一题(56~60/共5题)Part ⅤDaily ConversationDirections: Pick out the appropriate expressions from the eight Choices below and complete the following dialogues by blackening the corresponding letter on the Answer Sheet.A．Can I speak to Mr. Johnson, pleaseB．I'll tell him you've calledC．I'll give him the messageD．What can I do for youE．Can you tell him that we can meet tomorrow afternoon in my officeF．Can I take a messageG．Can you ask him to call me back as soon as possibleH．That's rightWoman: Hello, Mr. Johnson's office.Man: Good morning. 1 ?Woman: Sorry, he's in a meeting at the moment. 2 ?Man: Yes.

2017年专升本真题试卷.doc
2017年专升本真题试卷.doc专升本啊，这可真是个让人又爱又恨的事儿！我还记得当年我身边那些为了专升本努力拼搏的小伙伴们，那股子劲头儿，真是让人佩服。
咱们就先来说说这 2017 年的专升本真题试卷。
就拿英语来说吧，那阅读理解题，有的文章可真是不简单呐！有一篇讲的是关于环保新技术的，密密麻麻的英文单词，看得人眼花缭乱。
不过仔细一读，嘿，还挺有意思。
里面提到了一种新型的垃圾处理方法，说是能把那些难以降解的垃圾变成有用的能源。
我就想到了我们小区的垃圾分类，那叫一个混乱，要是能用上这种新技术，说不定能解决大问题呢！还有数学试卷，那些个函数题，真的是让人头疼。
有一道求极值的问题，我当时就在想，这要是在实际生活中，不就像是计算怎么用最少的钱买到最多的东西嘛！比如说去超市大采购，得算清楚怎么搭配商品才能最省钱。
语文试卷里的作文题目也挺有挑战性。
记得有一个是关于“梦想与现实”的话题。
这让我想起了我一个朋友，他一直梦想着成为一名摄影师，到处去拍美丽的风景。
可是毕业后，为了生计，不得不先找了一份安稳但和摄影没啥关系的工作。
他一边努力工作，一边利用业余时间继续钻研摄影技术，参加各种摄影活动。
这不就是在梦想和现实之间努力寻找平衡嘛。
再说那专业课的试卷，就拿计算机专业来说。
有一道编程题，要求设计一个简单的数据库管理系统。
这让我想到了现在各种手机 APP 背后的数据管理，要是这个系统没设计好，那软件用起来肯定卡顿、出错。
做这些真题试卷的时候，就像是在闯关打怪。
每一道题都是一个小怪兽，得集中精力，运用自己学到的知识和技巧去打败它们。
有时候一道题卡半天，那种抓耳挠腮的感觉，真的是让人着急。
不过，做完一套试卷，那种成就感也是满满的。
就好像自己又攻克了一座城堡，离目标又近了一步。
对于准备专升本的同学来说，这些真题试卷可太重要了。
通过做真题，能清楚地知道考试的重点在哪里，题型是啥样的，自己的薄弱环节又是什么。
然后有针对性地去复习、去提高。
