第一篇
Why does the professor ask the man to come to her office
A.to check on the man’s progress on a paper he is writing
B.To show the man techniques for organizing his time
C.To encourage the man to revise a paper he wrote
D.To clarify her comments on a paper the man wrote
答案：C
解析：24s 开始
主旨题，教授说Oh, sorry! It’s not for your grade. It's…I think you could learn a lot by revising it. 说明虽然不会影响成绩，但是他还是想让男生修改他的论文，因为他可以从中学到更多的东西。A，B 为无关选项，D 稍微有些干扰，但是主旨依然是鼓励男生改文章。
Why does the man hesitate before agreeing to the professor’s request
A.He is not sure his effort would be successful.
B.He feels overwhelmed by all his schoolwork
C.He is unclear about what the professor wants his to do.
D.He does not like to work on more than one assignment at a time.
答案：B
解析：
(原文中)There’re deadlines wherever I turn and… and I don’t really know how much time I could give it….it is a busy time, with spring break coming up next week. It’s your call. 推理题。男生听了教授的话震惊了。两句话都体现了男生的难处。原因是要放假了作业都要交了。AC 都是无关项，D 为干扰项，因为也说了很多作业，但是男生没有表明自己不喜欢一次做很多作业。正确答案为B。
What is the professor’s main criticism of the man’s paper
A.It included unnecessary information.
B.It did not include enough examples to illustrate the main point.
C.The main point was expressed too abstractly.
D.The paper ignored a key historical fact.
答案：A
解析:
(原文中)Anything unrelated to the use of nature EMITRY has no place in the paper. All that tangential material just distracted from the main argument. 细节题。教授表明学生太想扩大文章的范围导致过于冗杂，所以需要删减。BC 是无关项，D说反了，教授要求男生删除历史资料部分，而不是说遗漏了一个关键的历史资料。
Why does the professor suggest that the student change the introduction of his paper
A.To make it less repetitive
B.To more clearly state the man’s point of view.
C.To correct spelling and grammar mistakes.
D.To reflect changes made elsewhere in the paper.
答案：D
解析：
细节题。教授具体提出了要求：you’ll have to revise the introduction too, to accurately describe what you do in the body of the paper. D 选项几乎就是同义替换，因此为正确答案。
5.What does the professor mean when she says this: “Tell me about it!”
A.She understands the student’s problem.
B.She wants the student to explain his comment.
C.She did not hear what the student said.
D.She does not accept the student’s excuse.
答案：A
解析：
推论题。“Tell me about it! All writers struggled without one. But it’s something you can learn.” Tell me about it 在口语有“我和你有相同的经历，我很赞同你的观点”的意思，因此这里教授的意思就是，我很理解你现在的烦恼，因为我也有过相同的经历。正确答案选A。
本题也可以用排除法。教授在听到学生的问题后亲切地提出了自己的建议，因此说明她知道学生刚刚说了什么， 所以C是无关项。教授没有要学生提出评论，因此B 也是无关项。教授没有表示不接受他的借口，D也是无关项。
第二篇 Biology
6.What does the professor mainly discuss
A.How genes control human development.
B.Why various types of human cells divide at different rates.
C.How human chromosomes differ from one another.
D.Why most human cells cannot keep dividing successfully.
答案：D
解析：
主旨题。“we can explain a very important observation,”引出话题，即细胞分裂的次数是有限的，因此不能一直分裂。B 项为干扰项，但是教授并没有对B项的内容进行解释，因此是错误的。
7.The professor discusses research about the percentage of a chromosome’s DNA that contains genetic information. How did she feel about this research
A.She doubted its accuracy.
B.She was surprised by its conclusion.
C.She was concerned about its implications.
D.She thought it was unnecessary.
答案：B
解析：
细节题。“they were amazed, we all were, to find that only a fraction of it, maybe
20-30%, converts into meaningful genetic information.”此句为重点句，表示大家都对”只有 20%-30%的 DNA存在有意义基因”这个结果感到惊讶。其余选项都不合适。
8.What does the professor say about the DNA in a telomere
A.It causes a cell to begin dividing.
B.It separates one gene from another.
C.It is genetically meaningless.
D.It has no function.
答案：C
解析：
细节题。教授在 telomere (n.端粒) 的定义的下句中指出：“Now a telomere is a highly repetitious and genetically meaningless sequence of DNA, what we were calling JUNK DNA.” 教授说telemere被称为JUNK DNA垃圾基因，说明它是genetically meaningless的。选C。
9.Why does the professor mention shoelaces
A.To point out that chromosomes are arranged in pairs.
B.To describe the coiled shape of a chromosome.
C.To illustrate how chromosomes are protected from damage.
D.To explain how chromosomes are joined before dividing.
答案：C
解析：
目的题。教授通过举鞋带末端的塑胶部分的例子，来解释 telomere 的作用。“protect the genes the genetically functional parts of the Chromosome from being damaged.”两样东西都起到了同样的作用，塑胶部分是用来保护鞋带的，因此teleomere的作用就是保护chromosomes的，选C。
10. What does the professor imply about the length of the telomeres on a cell’s chromosomes
A.Longer telomeres allow the cell to divide more times.
B.Longer telomeres contain more genetic information.
C.Shorter telomeres are wound into tighter coils.
D.Shorter telomeres are less likely to break.
答案：A
解析：
细节题。教授指出，端粒会随着染色体的分裂变得越来越短“So after each division, the telomere gets shorter”，因此，端粒越长，可允许分裂次数越多。AC 是无关项，D项正好说反了。
11.According to the professor, how is the chemical telomerase related to the telomere
A.It resembles the telomere in structure.
B.It helps repair broken telomeres.
C.It is produced at the end of telomere.
D.It prevents telomeres from becoming too long.
答案：B
解析：
细节题。教授介绍了端粒当中存在的一种酶(enzyme)：telomerase，即端粒酶，学名是核糖体蛋白酶。“this chemical, this telomerase can rebuild it, can help reassemble the protected DNA,”端粒酶可以修复端粒，B 选项符合题意。CD为无关项。A 项在语音上面有干扰作用，不是 resemble，应为 reassemble，A 选项意为: 端粒和端粒酶在结构上相似。
第三篇 Business
12. What is the lecture mainly about
A.Two competing theories of business management.
B.Tools that business managers can use to improve the efficiency of their employees.
C.A method for business to learn about the needs of their customers.
D.A way that business managers can better relate to their employees.
答案：C
解析：
主旨题。教授在阐述之前上课的内容后介绍了 MBWA，“I want to describe a very simple method of researching customer preference.”，解题关键词是method。其余选项后文中都未提到。
13. According to the discussion, what is a potential drawback of MBWA
A.MBWA provides information about the opinions of a small number of people.
B.MBWA can provide conflicting information.
C.Customers are often reluctant to share their opinion.
D.Customers may be annoyed about being observed while they shop.
答案：A
解析：
细节题。Lisa 同学的提问便是 A 选项，教授给予认同：“and Yes, the numbers of opinion you get is small so you do need to be careful”。C 选项存在干扰，后面的男生的问题就是这个，但是教授否定了这个问题，大家都很愿意回答高管提出的问题：“Most customers have exactopposite reaction when they comes to MBWA.”
14. What does the professor say about the relationship between MBWA and market research
A.MBWA is a refined version of a market research technique.
B.Market research information is more valuable than information from MBWA.
C.Information provided by MBWA complements information collected from market research.
D.Business managers should replace market research with MBWA.
答案：C
本题需要对听到的内容进行一定的概括，必须懂得 complement 这个单词(v.互补)。很多句话里都可以看出，教授并没有得出市场调查和 MBWA 哪个较好的结论，他只是说“but MBWA is really useful kind of filling in the blanks.” BD 项错误。A 项中说MBWA 是市场调查的微观形式，其实两者不是包含关系，因此A项错误。
15. Why does the professor mention Dalton’s soup and Elkin jeans
A.To illustrate that the success of MBWA often depends on the product involved.
B.To give examples of two companies that were resistant to trying MBWA.
C.To contrast a successful use of MBWA with an unsuccessful use.
D.To give examples of how the technique of MBWA is used in practice.
答案：D
解析：
例子题，文中的前两个例子，Dalton’s soup跟Elkin jeans都是成功的案例，所以 BC 两项错误，A项是无关项。
16. Why does the professor discuss the mayor of Baltimore
A.To explain the origins of the method of MBWA.
B.To demonstrate that MBWA can be useful outside the business world.
C.To provide an example of MBWA can sometimes fail.
D.To give an example where market research and MBWA provide similar types of information.
答案：B
解析：
例子题。在介绍例子前，教授说到：“they have actually been extended to all kinds of different contacts like politics for instance” 即 MBWA 的使用范围已经拓展到了其他领域，，且这是一个成功例子。C项错误。AD 均为无关选项。
17. What does the professor imply when she says this:
“I mean, when Daltans of all the companies, embraces something as radical as MBWA, it really show you how popular the theory has become”
A.It is surprising that Dalton’s tried to use MBWA
B.It is surprising that MBWA was successful for Dalton’s.
C.She does not have a high opinion of the quality of Dalton’s soups.
D.Dalton’s positive experience with MBWA led many other companies to try MBWA.
答案：A
解析：
重听题。原文中用了 radical，表明教授对于 MBWA 的看法其实是不完全赞同的，但是大公司们纷纷采用了这种方法，她必须承认，此方法是有效的。综上所述，其实教授对于 DALTON这样的大公司采取这种方法，其实是很惊讶但是又不得不接受的。

男生问秘书为什么没人告诉他电脑崩溃的事情，女秘书坦言她也不知道那边的工作情况，但是每学期总要出问题，因此 B 项正确，财务处的员工没什么组织纪律性。
A 选项容易错选，其实财务处知道他们的电脑坏了，只是不知道谁的信息丢失了而已，所以他们是意识到自己有问题的。其余选项均未提及。
4.What will the student probably need to do to get paid
A.Talk to the person who hired him.
B.Go to the payroll department.
C.Call the director of the payroll department.
D.Resubmit the payroll paperwork.
答案：D
解析:

第五篇 Music History
6.What is the lecture mainly about
Click on 2 answers
A.Some changes that took place in the early years of opera.
B.Difference between opera and other forms of music.
C.Italy’s musical influence throughout Europe.
D.Reasons that early French and Italian opera did not survive.
答案：AC
解析：主旨题。全文都是关于歌剧的起源和变迁过程，讲座开头提到歌剧起源于意大利，因此歌剧在欧洲的传播过程就是意大利在音乐上对欧洲的影响，因此 AC 两项正确。全文只在讨论歌剧，因此 B 项错误;早期法国和意大利歌剧灭亡的原因也没在听力材料中被提及，因此D项错误。
7.According to the professor, what happened after the Italian language replaced Latin in Italian opera
A.Operas became much longer.
B.Operas begin to express secular ideas.
C.Music in opera became more complex.
D.Opera was used to teach technology to the general public.
答案：B
解析：
正确选项中的 secular 意为“世俗的”。讲座开头提到歌剧早期的主题都与宗教有关，可人们在日常生活中都是用意大利语交流，随着时间的推移歌剧的语言变成了意大利语，表演地点从教堂转移到了广场上，主题也都是对于政府和社会的讽刺，因此 B 正确。其余选项均未提及。
8.Why does the professor mention ancient Greek theater
A.To give an example of a culture that adopted opera from the Italians.
B.To describe the type of setting in which opera was typically performed.
C.To point out a precursor of opera.
D.To explain how opera was introduced into French society.
答案：C
解析：(原文中)It is the melodious drama of ancient Greek theater, the term ‘melodious drama’ being shortened eventually to ‘melodrama’ because operas frequently are melodramatic, not to say unrealistic. And the group that put the first operas together that we have today. 教授提到古希腊歌剧院，为了引出歌剧的前身(precursor)，因此 C 项正确。
9.What does the professor say about music in French opera
A.It resembled sacred church music.
B.It often inspired French novelists to write great piece of literature.
C.It revolved mainly around solo pieces.
D.It was secondary to the rhythmic flow of language.
答案：D
解析：
(原文中)The French said opera auto-reflect the rhythm and Kevin of dramatic literature, bearing in mind that we are talking about the golden age in French literature. And so the music was secondary. 信号词“so”引出一个小结论：法国人认为歌剧的歌词最富有节奏，因此音乐就是第二重要的了。选项 D 正确。其余选项均未提到。
10. Why does the professor say this:
A.To show difference between English and Italian opera.
B.To give one instance in the evolution of opera.
C.To discuss the popularity of opera in England at the time.
D.To point out that English and Italian opera companies often worked together.
答案：B
解析：重听题。“The English made a major adjustment to opera and exported what they had done to opera back to Italy.”英国人改变了歌剧并将其传回了意大利，这也是歌剧发展史的一部分，所以教授提及这部分只是为了给出歌剧发展史中的一个事件。AD 为无关项，重听句没有提及歌剧的流行程度，因此C项错误。
11.What does the professor imply when he says this:
A.He agrees with Chapman about opera and society.
B.He thinks Chapman’s approach to opera is confusing.
C.He is concerned that Chapman’s ideas are often misunderstood.
D.He thinks Chapman’s questions are difficult to answer.
答案：A
解析：(原文中)George Champon wrote about opera, “If an extraterrestrial being or two appear before us and say, what is your society like, what is this Earth thing all about, you could do worse than take that creature to an opera.” Because opera does, after all, begin with a man and a woman and any motion.教授在重听句中没有表达任何反对意见，亦或是对于George Champon这个人的评价，所以答案为 A。
第六篇 Environmental science
12. What is the lecture mainly about
A.An efficient solution to the problem of storing solar energy.
B.Energy policies in the twentieth century.
C.Reasons that solar energy is not more widely used.
D.The superiority of solar energy to oil and natural gas.
答案：C
解析：讲座介绍了太阳能利用的历史和现状，说明了太阳能的缺点，并由此阐述了太阳能不能广泛使用的原因。因此 C项正确。
13. What are the two main problems solar power presents as an energy source
Click on two answers
A.It is a potentially dangerous source.
B.It is difficult to concentrate.
C.It is scientifically unsound.
D.It needs to be stored.
答案：BD
解析：
出处一：Professor :Can anyone think of why it’s so difficult to make use of solar energy
Student A :Because it is hard to gather it
Professor :That’s exactly it.
出处二：That is the biggest drawback to solar energy. The problem of what do you do in cases where the sun’s light is weak or virtually non-present. So the storage of solar energy, lots of solar energy, is a really important aspect.
综合原文，太阳能的最大两个问题就是存储和收集，分别在文中教授回答学生两次问题时出现。
14. According to the professor, what led to the popularity of solar energy in the 1970’s
A.New solar energy technologies.
B.Advertising campaigns by solar energy companies.
C.An increase in the price of oil and natural gas.
D.The depletion of Earth’s reserves of oil and natural gas.
答案：C
解析：细节题。(原文中)So what happened in the 1970s was oil and natural gas became very expensive very quickly. 70年代油气都太贵，太阳能开始流行起来，因此C项正确。
(原文中)Because oil and natural gas were...err...became scarce 教授对于这个问题的回答是否定的，因此D项错误。
15. What is the difference between passive and active heating systems
A.Passive systems are less reliable.
B.Passive systems are difficult to install.
C.Passive systems can be used at any location.
D.Passive systems work without mechanical support.
答案：D
解析：(原文中)No mechanical devices are used in passive heating systems. They operate with little or no mechanical assistance.由此可知，被动系统是不依赖任何机械设备的帮助的。因此D项正确。文中未提及两系统的地点限制，因此C项错误。
16. What is the professor’s opinion about the future of Kramer Junction power plant
A.He is uncertain about the future of the Kramer Junction plant.
B.He believes the Kramer Junction plant will become a major source of power.
C.He is certain the Kramer Junction plant will not be able to increase its capacity.
D.He thinks the Kramer Junction plant will have many competitors.
答案：A
解析：(原文中)but only time will tell if it will ever develop into a major source of power for that region, considering the economic and political factors involved. 教授在最后介绍了Kramer Junction power plant，也就是一个太阳能发电厂，当提及它的前景时，教授说道“only time will tell.”说明他对其未来也并不确定，因此选 A。其他选项均未提及。
17. What does the professor mean when he says that:
A.He thinks the student should know the answer.
B.He thinks the student has raised an important issue.
C.He wants the student to repeat his question.
