大学英语四级考试试题及答案解析三十九Word文档格式.docx

1、本文重点应该落在题目“应对灾难”上，重点写“如何应对”。提纲的1，2两点可以简略介绍，一笔带过。第3点是重点，要详细说明。考生是否考虑过“应对灾难”的话题呢?碰到这个话题，要如何解答?范文从心理上和行动上给出应对办法，是展开思路的好办法。这样的题目不仅考查英语写作能力，也考查我们对新鲜话题的应变能力。只有平时多积累素材、多练习，才能庖丁解牛，游刃有余。否则，语言能力再好也会成为“无米之炊”，写不出好文章来。二、Cloze（共20小题,共70.0分）There are 20 blanks in the following passage.

And how about in human?

4、To fill that（4） , scientist Agnesand her colleagues at the University of Muenster（5） 50 healthy elderly subjects. The（6） volunteer was 60 years old and overweight. The researchers（7） assigned the volunteers to one of three groups. Twenty people were instructed to reduce their daily calorie（8） by 30%

Her team plans to（19） larger studies to determine exactly（20） calorie restriction enhances memory.AreducingBdecliningCburningDincreasingA【本题分数】：3.5分考查动词辨义。根据上一句提到的on a diet“节食”，可推断此处应选择含有“减少”含义

8、的词，A和B都含有“减少”的意思，但decline指“谢绝；衰退”，不合句意，故选A。第2题 fetchesswellslengthensstretchesD考查动词辨义及短语识别。空格后的内容为时间，因而选用stretch“延续；伸展”。fetch后接具体事物；swell指体积膨胀；lengthen后接具体长度。第3题 upunderforsince考查短语识别。up to表示“多达”，符合句意。其他选项不与to搭配。第4题 vanityvacancyvacationpositionB考查名词辨义。根据上一句的提问，可推断该研究还没有在人类身上进行过，fill that vacancy表示“

9、填补空白”，故B正确。A“自负；虚荣心”，C“假期”和D“位置”均不合句意。第5题 registeredhiredrecruitedenrolledC该空所在句的subjects指“对象”，即科学家“招收”的实验对象，recruit表示“招收”，符合句意。register指“登记，注册”；hire指“招聘”，多用于工作方面；enroll指“入学；招纳新成员”，而此处只是招收研究对象，不是招收新的科学家，故不选。第6题 tallestyoungestaverageoldest考查语义逻辑。文章并没有将这些实验对象分别比较，这里只是指一个平均数值，应选C。第7题 purposefullybasic

10、allyrandomlyaccordingly由于这是一项实验研究，故为保证实验合理、科学，理应将研究对象随机分组，因而“随机”更符合逻辑，故选C。purposefully“有目的地；蓄意地”，basically“基本地；从根本上说”，accordingly“照着；相应地”。第8题 induceinsertinputintake考查形近词。根据下一句复现的名词intake“纳入；吸入”一词，可推断此处D为答案。induce“诱导”，insert“插入”，input“输入”，均不合句意。第9题 balanceddelicioustastyrich考查形容词辨义。通过前后对比，可知科学家将实验对象

11、分为三组，第一组限制饮食，“但仍保证_饮食”，balanced diet表示“均衡的饮食”，故A正确。delicious美味的”，tasty“好吃的”和rich“丰盛的”均与句意不符。第10题 expenseconsumptionassumptioncost此空应填的内容离不开“吃”这一层含义，选项中只有consumption可以表示对事物的“消费”，故为答案。expense用在金钱方面，而cost常用于金钱和时间；assumption与consumption形近，指“假定；臆想”，与句意无关。第11题 remainingmaintainingretainingsustaining文章提到科学

12、家将研究对象分为三组，前两组已提及，因而此处为第三组，remaining意为“剩下的”，符合句意。maintain,retain和sustain均为“保持”之义。第12题 gotmadetookheldtake常与test搭配使用，表示“参加测试”，其他选项的动词不与test搭配。第13题 WithinAtInOnon average表示“平均”，其他选项介同不与average搭配。第14题 dropdecreaseimprovementboost根据下一句复现的improvement可以推测，此处应选择含有“提高”含义的词，故选C。A和B与文意相悖；boost指“增长”，常用于经济方面，用于

13、此处不恰当。第15题 muchlittlemanyfew由后面的no improvement可知此空应填入具有否定意义的同，用以修饰不可数名词improvement，故用little。第16题 typicallyalreadyonlybarely语义逻辑题。根据转折连词but和最后一句中plans to后的内容可大致判断，此项研究所涉及的范围相对较窄，only一词恰好能体现这种含义。第17题 evidenceconfidencecorrespondenceincidence填入的内容作provides的宾语，evidence指“证据”，符合句意。其他选项只是其形近同，confidence“信心

14、”，correspondence“通信；一致”，incidence“发生率”均与句意不符。第18题 quickenedbroughtcomefollowedfollow up表示“跟进；追究”，符合句意。quicken up指“加快”，bring up指“抚养；提出”，come up指“出现；发生”，均不合句意。第19题 concedeconcernconductconceal填入的内容与studies搭配构成动词短语，根据but后面的内容推断计划加大他的研究，conduct作动词时意为“实施，进行”，故为正确答案。concede“承认；让步”，concern“涉及”以及conceal“隐藏”

15、均不合句意。第20题 whenhowwhetherwhatcalories restriction enhances memory是已知的结果，故不用whether，而how表方式，符合句意。三、Listening Comprehension（Section A）（共15小题,共105.0分）In this section, you will hear 8 short conversations and 2 long conversations. At the end of each conversation, one or more questions will be asked about

16、 what was said. Both the conversation and the questions will be spoken only once. After each question there will be a pause. During the pause, you must read the four choices marked A, B, C and D, and decide which is the best answer. Then mark the corresponding letter on Answer Sheet 2 with a single

17、line through the centre. She contained her happiness.She pretended to be cheerful.She thought the exam was hard.She was awfully pleased with her grades.7.0分听力原文 W: I dont understand why I received such a low grade on nay math exam.Judy seemed happy with her grades. M: Happy?She could perfectly conta

18、in herself. Q: What does the man say about Judy?解析 男士反问说“（她）高兴？她可以完全控制住自己（不流露真实的情绪）”，言下之意是说Judy并不是真的高兴，而是她凭借良好的自制能力（contain herself）装出来的，所以B正确。点睛 对话中提到Judy，要留意问题是与对话中女士有关还是与Judy有关，以确定选项中she的所指。恨据男士的反问语气（Happy？）可知男士认为Judy并不高兴，所以A、D意思均与男士的意思相悖；C对话中未提及。A carpenter.A painter.A gardener.A barber. Do you

19、want a shampoo?How would you like it cut,Sir? M: All right.Just trim the back,but leave it long on the sides,please. Q: Who is the man most probably talking to?解析 女士问男士是否要抹点洗发水，想要剪什么样的发型，由此推知女士是理发师，所以D正确。点睛 浏览选项，可知问题是问人的职业。根据shampoo，cut这两个关键词即可推断对话发生在理发店。A“木匠”，B“画家”，C“园丁”均不符合语境。Go for a later movie.

20、Order his food quickly.Go to another restaurant.Decide which movie to watch.听力原文 M: Im not sure what Im in a mood for?Vegetable or dessert?They are both really delicious here. W: The movie starts in half an hour and we still have to get there and park.So just make a decision. Q: What does the woman

21、suggest the man do?解析 女士说电影半个小时后就开始了，他们还要开车去那边，还要泊车，让男士快做决定。鉴于之前男士说不知道吃哪个，可知女士让男士快点点餐，B正确。点睛 动词原形选项，多问建议或计划。A与D利用对话中提到的movie制造干扰；C也与对话意思不符。She will deliver a speech at the convention.She is the only representative of her division.She helps to build a marketing system.She works in the marketing depar

22、tment. Hey,Joan.Whats that red pin you are wearing? W: Well,all the company representatives in the marking division have to wear them to the business convention. Q: What can we infer from the conversation about the woman?解析 女士说公司市场营销部的所有代表都要戴这个去参加商务会议，既然女士也戴着，她就必然是在营销部门工作，D正确。点睛 根据语境较容易作答。A属无中生有；B由女士所说的all. representatives可马上排除；C用marketing制造原词干扰。She forgot to make a call to the man.Her answering machine was broken.She didnt get the mans messages.She couldnt remember the mans number.
