2016年浙江大学博士生英语 听力 PART A Welcome to Everglades National Park. The Everglades is a watery plain covered with saw grass that's home to numerous species of plants and wildlife. At one and a half million acres, it's too big to see it all today, but this tour will offer you a good sampling. Our tour bus will stop first at T aylor Slough. This is a good place to start because it's home to many of the plants and animals typically associated with the Everglades. You'll see many exotic birds and, of course, our world famous alligators. Don't worry, there's a boardwalk that goes across the marsh, so you can look down at the animals in the water from a safe distance. The boardwalk is high enough to give you a great view of the saw grass prairie. From there we'll head to some other marshy and even jungle like areas that feature wonderful tropical plant life. For those of you who'd like a closer view of the saw grass prairie, you might consider renting a canoe sometime during your visit here. However, don't do this unless you have a very good sense of direction and can negotiate your way through tall grass. We'd hate to have to come looking for you. You have the good fortune of being here in the winter—the best time of year to visit. During the spring and summer, the mosquitoes will just about eat you alive! Right now they're not so bothersome, but you'll still want to use an insect repellent. Welcome to Everglades National Park.

Reading Text 1 Few social problems have increased so suddenly or been dramatized so effectively as the plight of the homeless in the 1980s and 1990s.Once an invisible people who could easily be ignored, the homeless are now recognized everywhere on the streets and in the public facilities of major cities. There are bag ladies who roam the streets carrying what is left of their possessions in shopping bags or grocery carts. There are disoriented men curled up on benches, in stairwells, or alongside walls. There are children – some runaways and some throwaways scrounge(偷，骗取) for food and shelter. The number of homeless people in underdeveloped societies in the mid-1980s was estimated by the United Nations (UN) to be more than 100 million. The so-called “new”homeless live in the developed, industrialized nations of Europe, North America, and East Asia. Accurate statistics have been impossible to verify, in part because of the conflicting viewpoints on the subject of homelessness. Politicians, lawyers, and others who become advocates for the homeless have said that there are from 2 to 3 million homeless in the US alone. Others who have studied the problem from a less sympathetic point of view suggest that the

2011年浙江大学考博英语真题听力原文，仅供参考 第一篇 Among my experiences as a college president is the all‐too‐frequent phone call in the night that begins: "One of your students is in the emergency room with alcohol poisoning." The whole country got a similar wake‐up call in Ju ne when it was reported that alcohol abuse on college campuses is on the rise, especially for women, and that college students drink far more than nonstudents. One statistic showed that college students spend more money on alcohol while in college than on books. Alcohol abuse, although tragic, is but one symptom of a larger campus crisis. A generation has come to college quite fragile, not very secure about who it is, fearful of its lack of identity and without confidence in its future. Many students are ashamed of themselves and afraid of relationships. Students use alcohol as an escape. It's used as an excuse for bad behavior: the insanity defense writ large on campus. This diminished sense of self has caused a growth in racism, sexism, attempted suicide, theft, property‐damage and cheating on most campuses. This is not the stuff of most presidents' public conversations. Nor can it be explained away as an "underclass" problem; it is found on our most privileged campuses. It is happening because the generation now entering college has experienced few authentic connections with adults in its lifetime. I call this the "Culture of Neglect," and we — parents, teachers, professors and administrators — are the primary architects. It begins at home, where social and economic factors — such as declining incomes requiring longer work hours — result in less family time. Young people have been allowed to or must take part‐time jobs rather than spending time in school, on homework or with their families. More children and youths are being reared in a vacuum, with television as their only supervisor, and there is little expectation that they learn personal responsibility. Immersed in themselves, they are left to their peers. 31. The main idea of the first paragraph is that ( ) . ×正确答案为C [A] it is easy to be a college president [B] a college president has to sit up till midnight [C] alcohol abuse is quite common on campus [D] it is harmful for college students to drink alcohol 32. According to the author, college students turn to alcohol as a(n) ( ). ×正确答案为C [A] inspiration [B] stimulation [C] escape [D] relaxation 33. The word "architects" in Para. 2 can be best replaced by ( ). ×正确答案为D [A] artists [B] experts [C] discoverers [D] designers 34. How do parents react to the "Culture of Neglect"?( ) ×正确答案为B [A] Parents have lowered their expectations on children. [B] Parents take little care of the growth of their children. [C] Parents spend too much time watching television.

学苑教育考博辅导老师为您提供备考建议，希望对您有所帮助。 Today,cigarette smoking is a common habit. About forty-three percent of the adult menand thirty-one percent of the adult women in the United States smoke cigarettesregularly. It is encouraging to see that millions of people have given upsmoking. It is a fact that men as a group smoke more than women. Among both men andwomen the age group with the highest proportion of smokers is 24-44. Income, education, and occupation all play a part in determining a person’ssmoking habit. City people smoke more than people living on farms.Well-educated men with high incomes are less likely to smoke cigarettes thanmen with fewer years of schooling and lower incomes. On the other hand, if awell-educated man with a higher income smoked at all, he is likely to smokemore packs of cigarettes per day. The situation is somewhat different for women.(80)There are slightly moresmokers among women with higher family income and higher education than amongthe lower income and lower educational groups. These more highly educated womentend to smoke more heavily. Among teenagers the picture is similar. There are fewer teenaged smokers fromupper-income, well-educated families, and fewer from families living in farmareas. Children are most likely to start smoking if one or both of theirparents smoke. 1. What do we know from the first paragraph ? A.More and more people take up the habit of smoking. B. There are more smoking women than smoking men in USA. C. It is good news that more people have given up smoking. D. The U.S. has more smoking people than any other country. 2.What factors determine a person’s smokinghabits ?
浙江大学考博英语复试经验参考
浙江大学考博英语复试经验参考 一、题型分析 浙江大学近几年博士生入学考试题型分布： 听力(20分)、词汇(15分)、完型(20分)、阅读(20分)、翻译(25分) 考试时长3个小时。 分析真题的难度，听力、翻译略难于大学英语6级，其他和6级 难度基本保持一致。感觉浙大考博英语听力难度类似于6级阅读理解。 二、近几年分数线分析【总分线（听力线）】 03春：59（10）03秋：53（7） 04春：56（8）04秋：57（8） 05春：53（7）05秋：63（11) 06春：60（11)06秋：58（9) 07秋：50（8）08秋：50（6） 09年：55（8）10年：50（6） 11年：58（7）12年：60（9） 13年：60（10）14年：60（10） 15年：60（10）16年：60（10） 17年：60（12）18年：60 60分达标建议：平时做题听力单选至少要对7个以上，因听写得分很不容易，完型对13个以上，阅读对16个以上，翻译一般同学得 分会为10-15分。
三、评分细则 1.听力听写在宽松判卷情况下，写对关键词得0.5分，时态、单 复数错误只得0.5分。注意：如写的超过规定单词数，即使写的和听 力原文完全一样，也只有0.5分，这时需要想办法去掉不重要的单词，千万不要超过规定单词数。 2.翻译一般以10-15分为基准，亮点多会提升一个档次分数 （15-20分），以此类推，语言比一般同学的还要粗糙恐怕会给10分 以下。如有“低级下流”语句，比如Iis、youis等，可能直接给10 分以下。没写完的得分也会直接降低，如果真没时间写了，注意，赶 紧去写结尾。 一模一样内容，字写得工整整齐可能会高至少3分，总体感觉和 改考研作文一样，同样一个句子，有的同学写出来就是很美的复合句、连贯、浑然一体，有的同学则是简单粗糙、堆砌、上下文断裂，虽然 表达清楚了汉语内容。 四、相对应对策 1.过好词汇关 浙大英语总体词汇量偏重于英语6级，所以选一本6级高频词汇 作为记忆点，应付考试充足。建议上班族用手机里的APP(如扇贝单词、百词斩等)背记;建议应届生还是用高频词汇本。 背单词时，不要幻想背一次就充足了，如果基础好建议背两次， 基础一般的建议背三次，每天根据自己实际情况确定要被单词量先少 后多，词汇会慢慢熟悉起来，记的时候一定要熟读例句，并注重单词 各种形式、用法和读音。到了临考前二周左右，再拿起单词本或者APP 应该能够在一周内全部背完，此时词汇量完全能够应付考试。 此外，要用好真题词汇题。分析发现真题词汇会以不同形式重复 用法，建议每做完一套真题后总结分析词汇题，特别是对自己背过的 单词如果模糊的话，一定要去查，重点注重形近词、意近词和自己不
