A. To apply for a work-study job
B. To get information about hosting an exchange student
C. To find out if there are any jobs available on campus
D. To find out eh hours of the computer lab
答案：C
解析：(原文中)Professor : Oh! Ok! And that led you to our program. Right now though I think you are looking for a job.
Student: Yeah, a part time job on campus. I thought I’d save money, being away from the big city. But it doesn’t seem to be working that way. Anyway I’m not having much luck.
教授说我觉得你正在找一份工作，学生回答 yeah!a part time job on campus. 此时便可以判断正确答案为C选项。
Question 2.
Why did the student transfer to Central University?
A. To take advantage of an academic program
B. To participate in a student exchange program
C. To attend a smaller university than the one he was at before
D. To benefit from Central University's international reputation
答案：A
解析：(原文中)Student：But Northeastern is still fairly small. And it doesn’t have the program I’m interested in. I want to major in international studies. And the only program in the State is here.
Professor 问学生为什么要来Central University，学生说东北大学没有他喜欢的专业，他感兴趣的program 只有这里有，言下之意他来这里是为了program的。所以答案选 A 。
Question 3.
Why does the student mention hosting foreign-exchange students?
A. To explain his interest in a particular field of study
B. To explain why he is looking for a job so late in the semester
C. To explain why he would like to be an exchange student the following year
D. To explain how he learned his computer skills
答案：A
解析：(原文中)Professor: We do have a great program. Well how did you get interested in international studies?
Student: My family hosted a few foreign exchange students while I was growing up. Then I took part in an international summer program after I graduated from high school. I thought I really I like meeting people from all over, getting to know them.
学生的回答中提及他之前的经历是为了解释他对 International studies 感兴趣的原因。所以答案选 A。
Question 4.
What can be inferred about students who apply for the open position at the technology-support helpdesk?
A. They must be enrolled in a computer course.
B. They will only be able to work on weekends.
C. They are willing to work many hours each day they work
D. They are willing to work irregular hours.
答案：D
解析：(原文中)Student: Something every diplomat needs. But is there some problem? I mean why is the job still open?
Professor: Well, they have extended hours, from 6am to 2am every day. So they need a large staff. But right now they only need people early mornings, late nights, and weekends. You’d probably end up with a bit of everything rather than a regular spot.
注意题干中有 infer，说明这个问题要通过文章推断出来。学生好奇为什么 tech-support 的工作还有呢?接下来教授解释了原因，现在只需要一些特定时间工作的人，early mornings, late nights等等，最后一句总结工作时间是不规律的，答案选 D。
Question 5.
Why does the woman say this?
A. To dissuade the student from starting a job right way.
B. To suggest looking for an off-campus job.
C. To imply that the student might not like the job that is available.
D. To encourage the student to apply to a work-study program.
答案：C
解析：(原文中)Professor: Well, I guess each school has its own policies. Uh, we really don’t have much right now. You might be better. If you really want something, how are your computer skills?
Student: About average I’d say. I helped teach some of the basic computer classes. Northeastern offers for new users, if that helps any.
这道题要结合语境，之前学生说了他找 part-time job碰壁，图书馆不要人。教授表示每个学校都有自己的政策，并且说他们这儿所剩工作也不多了。因此，她后面 offer 男生的工作应该也不会是很好的。所以应该选 C。
Lecture 1
Question 6：
What is the lecture mainly about?
A.The importance of record keeping in the development of hypotheses
B.The relationship between sunspots and Earth's geomagnetic cycle
C.The progression of scientific knowledge about sunspots
D.The effect of sunspots on Earth's climate
答案：C
解析：lecture 是关于太阳黑子的 study，并阐述了随着时间的推移，这个 study 不断进步。先是欧洲人根据自己的 belief 主观臆断再到伽利略通过望远镜观察提出了 challenge， 然后到两位学者长年的研究发现太阳黑子数量变化和地磁周期，这些都可以看出lecture 的主旨是在说人类对于太阳黑子的科学认知的不断演变的过程。因此答案选 C。
Question 7：
Why did European astronomers before the time of Galileo not believe sunspots were on the Sun's
surface?
A.They based their beliefs on earlier observations by Chinese astronomers.
B.The idea was contrary to their beliefs about objects in space.
C.The sunspots often changed their shape.
D.The sunspots were not always visible.
答案：B
解析：(原文中)Professor : When later European astronomers wrote about sunspots, they didn’t believe that the spots were actually on the Sun. That’s because of their belief at the time that the heavenly bodies, the Sun, Moon, Stars, and Planets, were perfect, without any flaws or blemishes.
That’s because 是比较明显的提示词。欧洲宇航员对太阳黑子的“偏见”源于他们对天体的认知，他们一直以来都认为天体是完美的，不可能有个黑点在上面。 所以答案选 B。
Question 8：
Which hypothesis regarding sunspots did Galilee Challenge?
A.Sunspots are shadows of planets trussing the Sun.
B.Sunspots are cloud in the solar atmosphere.
C.Sunspots are evidence of the Sun's rotation.
D.Sunspots are evidence of magnetic fields.
答案：A
解析：(原文中)So the opinion was the spots were actually something else, like shadows of planets crossing the Sun’s face. And this was the thinking of European astronomers until the introduction of the telescope, which brings us to our old friend, Galileo. In the early 1600s, based on his observations of sunspots, Galileo proposed a new hypothesis.
欧洲宇航员的观点持续到望远镜的发明——我们的老朋友伽利略的杰作。可以推断出天文望远镜的出世挑战了欧洲宇航员之前对太阳黑子的观点——shadows of planets crossing the Sun’s face.。所以很清楚答案选 A。
Question 9:
What was the importance of Schwabe's observations?
A.They determined the age of sunspots.
B.They established that sunspots appear in cycles.
C.They proved that sunspots were actually on the Sun.
D.They showed the reason that sunspots change their shape
答案：B
解析：(原文中)Then in 1843, astronomer named Heinrich Schwabe made an interesting claim, Trobe had been watching the Sun every day that it was visible for 17 years, looking for evidence of a new planet. And he started keeping tracks of sunspots, mapping them, so he wouldn’t confuse them, so he wouldn’t confuse them with any potential new planet. In the end, there was no planet, but there was evidence that the number of sunspots increased and decreased in a pattern, a pattern that began repeating after 10 years, and that was a huge breakthrough.
1843 年一个伟人出现了，他研究了很久。我们的注意力要放在In the end 和 but 上面，一般转折后面通常会有考点。听到a pattern that began repeat after 10 years之后，我们就可以确定答案选择 B。
Question10：
What is the professor’s attitude toward Schwabe's and Wolf's research?
A.He is surprised that the research is contradictory.
B.He is impressed by how many years were spent on the research.
C.He has difficulty believing that research should take so long.
D.He doubts that the research is given enough credit by modern astronomers
答案：B
解析：(原文中)So Wolf did 40 years of research, and Trobe did 17 years of research. I think there is a lesson there. Anyway, Wolf went through all records from various observatories in Europe and put together a history of sunspot observations going back about 100 years.
这道题目主要听的是语气。教授在读到这两位学者研究的时间分别是 40 年和 17 年的时候，都用了重读，可见他对这两个人的研究时间印象很深刻。C 选项太过偏激，文章中并没有表现作者对研究时间之长难以置信。所以答案应该选 B。
Question 11：
Why does the professor imply about the discovery of a relationship between the sunspot cycle and Earth's geomagnetic cycle?
A.It proved that Gallieo's cloud hypothesis was correct.
B.It showed how conditions on Earth can affect the Sun.
C.It was the start of modern astronomy.
D.It led to a period of intense scientific research.
答案：D
解析：(原文中)Well, we’ll cover this later in this semester, but for now, well, scientists in the late 19thcentury were aware of geomagnetic cycles, so when they heard that the sunspots’ cycle was also 11 years, well, they just had to find out what was going on. Suddenly, everyone was doing studies of the possible relationship between the Sun and the Earth.
这道题是 but 领衔的考点。太阳黑子循环周期和 geomagnetic cycle 之间关系的发现激发了科学家们的研究热情，很多人都去研究这个课题了。文中强调的 Everyone 和 Intense 相呼应，答案选 D。
Lecture 2
Question 12：
What is the lecture mainly about?
A.Different views of a type of sculpture popular in ancient Roman times
B.Evidence that Romans had outstanding artistic ability
C.The differences between Greek sculpture and Roman sculpture
D.The relationship between art and politics in ancient Roman times
答案：A
解析：(原文中)Essentially, the traditional view, a view that’s been prevalent for over 250 years, is that the Romans copied Greek sculptures because they couldn’t create sculpture of their own. But finally some contemporary art historians have challenged this view. One is Elaine Gazda .
根据这段话并结合全文，Lecture 讲了对于罗马雕塑---copies 的 view。Traditional 认为罗马人技能不行，所以 copy了希腊人的。Gazda 认为罗马雕塑有双重意义。作者又通过 coin 和 emperor 头颅的例子阐述了罗马雕塑---copies of Greek sculpture 的价值和功能。所以答案选 A。
Question 13：
According to traditional art, why did the Romans copy Greek sculpture?
A.The Roman public was not interested in original works of art.
B.The Roman government did not support other forms of art.
C.Roman artists did not have sufficient skill to create original sculpture
D.Romans wanted to imitate the art they admired.
答案：C
解析：(原文中)Now the dominant view in traditional art history is that Roman artists lacked creativity and skill especially compared to the Greek artists who came before them. Essentially, the traditional view, a view that’s been prevalent for over 250 years, is that the Romans copied Greek sculptures because they couldn’t create sculpture of their own.
传统的艺术中的观点就是罗马艺术家们缺乏创造性和制作 sculpture的skill，特别是和走在他们前列的希腊艺术家们相比，罗马人copy 希腊人的sculpture主要是由于他们不能创造他们自己的。
Question 14：
What is Gazda's view of the Roman copies of Greek statues?
A.The copies represented the idea that Roman society was similar to Greek society.
B.The copies introduced the citizens of the Roman Empire to Greek history.
C.The copies were inferior to the original statues.
D.The copies had both artistic and political functions.
答案：D
解析：(原文中)So Gazda hypothesizes that copying didn’t indicate a lack of artistic imagination or skill on the part of Roman artists, but rather the Romans made copies because they admired Greek sculpture. Classical Greek statues represented an idealization of the human body and were considered quite beautiful at the time. Gazda also believes that it’s been a mistake to dismiss the Roman copies as, well, copies for copy’s sake and not to consider the Roman function and meaning of the statues.
But 、rather 作为标志词，起到强调的作用。在这道题中，这是 Gazda的一部分观点，罗马人 copy 希腊人的雕塑就是因为欣赏。Also 是另一个标志词。Gazda 认为没有考虑罗马雕塑的作用和意义是错误的，言下之意就是，罗马人 copy 希腊人的雕塑还有除艺术原因之外的原因。四个选项中，D 是最恰当的。
Question 15：
Why does the professor mention Roman coins?
A.To show the similarity between the likenesses of the emperor in statues and on coins
B.To illustrate the Roman policy of distributing the emperor’s image throughout the empire
C.To imply that the citizens of the Roman Empire became quite wealthy
D.To suggest that the Romans also copied Greek art on their coins
答案：B
解析：(原文中)Professor: Well, not necessarily. Under the Emperor Augustus at the height of the Roman Empire, portrait statues were sent throughout the empire. They were supposed to communicate specific ideas about the emperor and the imperial family and to help inhabitants of the conquered areas become familiar with the Roman way of Life. You know, Roman coins were also distributed throughout the empire. Anybody care to guess what was on them?
Student：The emperor’s face?
Professor: That’s right! The coins were easy to distribute and they allowed people to see the emperor or at least his likes and served as an additional reminder to let them know, well, who was in charge.
教授说 sculpture 不仅仅只是装饰，，可以让大众了解执政者的容貌。为了证明这一点，他用了 coin 来类比。Highlight 的部分介绍了 coin 的功能。比较四个选项，B是正确答案。
Question 16：
According to the professor, why did the Romans sometimes remove the emperor's head from a statue? Click on 2 answers
A.The head made the statue too heavy to transport.
B.The head was placed on the body of a different statue.
C.The emperor was no longer in power.
D.The emperor was not satisfied with the quality of the statue.
答案：BC
解析：(原文中)And on some statues the heads were removable. They could put an emperor’s head on different bodies, showing him doing different things. And then later when the time came they could even use the head of the next emperor on the same body.
B 这个选项很容易就选出来了，C 的选项隐藏的比较深，不过有一些 infer。用上一任的身体，下一任的脑袋暗指执政者换人后原来执政者的 head 是要被 remove 的。
2、The coins were easy to distribute and they allowed people to see the emperor or at least his likes and served as an additional reminder to let them know, well, who was in charge.，为了让人民知道谁在掌权，那么如果执政者换人了，自然而然就要换头像，不然人民怎么知道谁在掌权呢。或者可以用排除法， A D 在通篇文章都没有提及。故答案选 BC。
Question 17：
What does the professor imply when he says this:
A.Art historians frequently change their views.
B.The contemporary view is not easy to understand.
C.It is not difficult to determine why the Romans copied Greek sculptures
D.The view of traditional art historians is probably incorrect
答案：D
解析：(原文中)Essentially, the traditional view, a view that’s been prevalent for over 250 years, is that the Romans copied Greek sculptures because they couldn’t create sculpture of their own. But finally some contemporary art historians have challenged this view.
Highlight 部分作者语速变缓且重读。说明 finally 前后的观点是相互冲突的。因此暗示出作者暗指 traditional 的观点是错误的。答案选 D。
Section 2
Conversation 2
Question 18：
What is the conversation mainly about?
A.The topic of the man's research paper
B.Some current research projects in sociology
C.Effective ways of conducting sociology research
D.The man's possible participation in a research project
答案：D
解析：(原文中)Professor: ….So did you have a question?
Student: Yeah, it’s about…you mentioned needing volunteers for a research study?
Professor: Yep, it’s not my study.
文章上来先说了学生论文轮廓的事情，之后开始转向主题：the volunteer for study。学生找老师的目的是对于这个 research study 有兴趣，全文主要也是在聊关于这个 study 的，包括它的研究内容，还有师生俩在磋商时间等等。因此答案选 D。
Question19：
What does the professor imply about the man's outline?
A.It has revealed that he should limit the focus of his paper.
B.It does not provide enough information for him to write the paper
C.It will help him write clearly about a complex topic.
D.It overstates the connection between sociology and marketing.
答案：C
解析：(原文中)Professor: Well, I’m glad you redid your outline. I fed a few comments, but nothing you have to act on. It’s in good enough shape for you to start writing your paper.
Student: Thanks! At first I was afraid all that prep work would be a waste of time.
Professor: Well, especially with a challenging topic like yours: factors leading to the emergence of sociology as an academic discipline.
这个教授看过学生重写的paper 轮廓了，她认为文章的轮廓达到可以开始写这个challenge topic的要求。很明显，答案选 C。
Question 20：
What is the main goal of the study that the professor’s colleague is conducting?
A.To find out if some television shows will be popular with people in a certain age range
B.To collect information about food products that college students like
C.To generate ideas for new television shows
D.To determine sociologicalfactors that are related to people's television-viewing preferences
答案：A
解析：(原文中)Professor: She needs people to watch various new TV programs that haven’t been broadcast yet, then indicate on a survey whether they liked it, why, if they’d watch another episode. It’d be kind of fun plus participants get a $50 gift certificate.
Student: Wow, well I like the sound of that. But…so they are trying to predict if the shows are gonna succeed or fail, right, based on students’ opinions?
这个 study 的 goal 是为了判断年轻人对于一些电视节目的喜好。Student 又以问句的形式再一次点出了 study 的主题。所有选项中 A 最为接近。
Question 21：
What does the professor imply about the owners of Fox's Diner?
A.They would probably do a favor for her.
B.They are unlikely to grant the man's request.
C.They would enjoy participating in the research study
D.They often advertise on television.
答案：A
解析：(原文中)Professor: Oh, I like Fox’s. I eat there every week. Maybe you could switch shifts with someone.
Student: I’m still in training. And the only night my trainer works is Thursday. Look!
Professor: I know the owners there really well. Why don’t you let me give them a call and explain the situation?
Professor说fox diner的owner人很好，她想要打电话解释下现在这个情况。表明owner可能会帮他们的忙调整一下。答案选 A。
Question22：
What does the professor mean when she says this:
A.The student could probably find a marketing professor who has an interest in sociology.
B.The student's marketing professor might not be aware of the television study.
C.No more students are needed to participate in the television study.
D.The marketing department needs students for several research studies.
答案：B
解析：(原文中)Professor: Oh, you are taking the marketing class? Who’s teaching it?
Student: It’s Professor Largin - Intro to Marketing. Hr hasn’t mentioned the study though.
Professor: Oh, well, the marketing department’s pretty big. I happen to be friends with a woman who is doing the TV study.
教授问学生，谁教你市场课，学生说了个人教授不认识，得出结论——市场部很大。教授又说自己有个朋友正在做 TV-study, 言下之意就是学生的教授也许没听说过这个 study，因为市场部太大了。
Lecture 3
Question 23：
What is the main purpose of the lecture?
A.To explore the use of spices in conking in the Middle Ages
B.To explain the significance of spices for medieval society
C.To describe how the spice trade evolved in medieval Europe
D.To examine changes in the role that spices played in the Middle Ages
答案：B
解析：(原文中)Professor: In order to really study the social history of the Middle Ages, you have to understand the role of spices.
这篇文章的主旨属于典型的开门见山。整个 lecture 都在说 spices 对中世纪的欧洲有哪些影响。答案选 B。
Question24:
Click in the correct box for each phrase
YesNo
They had to be imported.Y
They were unaffordable for many people.Y
They were used to preserve meat during the winter.N
They were believed to have medicinal properties. Y
Their sale in public markets was closely regulated.N
答案：YYNYN
解析：(原文中)1. Now for cost and rarity, spices aren’t native to Europe and they had to be imported.
2. By the Middle Ages, spices were regarded as so important and expensive they were used in diplomacy, as gifts by heads of state and ambassadors. 中世纪的时候 spices 很贵，多用于外交，主要是送给首脑和大使的，因此很多人没有能力购买 spices.
3. Now, this is a good point to mention one of the biggest myths about spices. It’s commonly said that medieval Europeans wanted spices to cover up the taste of spoiled meat. But this isn’t really true. 教授指出了一个 common mistake，其实 spices 不是用于掩盖变质肉的气味的。
4. Spices inspired the medieval imagination. They were used as medicines to ward off diseases, and mixed into perfumes, incent.
5. 通篇都没有提到 spices 公共市场的规范程度。文中是有提到如果卖变质的肉是要被punish的，但是这个和 spices 的市场没有关系。
Question 25：
What two factors explain why medieval Europeans did not use spices to cover the taste of spoiled meat?
A.Fresh meat was less expensive than spices were.
B.Spices were mainly used in incense and perfume.
C.The sale of spoiled food was prohibited.
D.Salt was cheaper than most spices were.
答案：AC
解析：(原文中)Professor: Anyone who had to worry about spoiled meat couldn’t afford spices in the first place. If you could afford spices, you could definitely afford fresh meat. We also have evidence that various medieval markets employed a kind of police to make sure that people did not sell spoiled food, and if you were caught doing it, you were subject to various fines, humiliating public punishments.
Spice 不可能用来掩盖变质肉的气味因为：1.spice 比肉贵;2.punish 严格，market 不允许销售变质肉。
Question 26：
Why does the professor mention the collapse of the Roman Empire?
A.To indicate that the spice trade became mere direct
B.To explain why the price of pepper suddenly increased
C.To indicate that spices were not available in Europe for centuries
D.To explain why the origins of spices became more mysterious
答案：D
解析：(原文中)Professor: So the cook started looking for new ways to improve the taste and spices were the answer, which brings us to mysterious origins and mythical status. Now the ancient Romans had a thriving spice trade and they sent their ships to the east and back. But when Rome collapsed in the fifth century and the Middle Ages began, direct trade stopped, and so did that kind of hands-on knowledge of travel and geography.
本来古罗马有一条 spice 贸易通道。在古罗马帝国在五世纪崩塌了之后，spices 的直接贸易就停止了，关于航程和地理位置的信息也都丢失了。言下之意就是 spices 的出处变得更加神秘了。答案选 D。
Question 27：
What does the professor say about European explorers during the age of discovery?
A.Their discoveries caused the price of certain spices to increase
B.They were responding to the demand for spices.
C.They did not expect to find spices during their explorations.
D.Their main goal was to discover unknown lands.
答案：B
解析：(原文中)Professor: Spices inspired the medieval imagination. They were used as medicines to ward off diseases, and mixed into perfumes, incent. They were used in religious rituals for thousands of years. They took on a life of their own and they inspired the medieval imagination, spurred on the age of discovery in the 14th and 16th centuries. When famous explorers like Columbus and da Gama and Magellan left Europe in their ships, they weren’t looking for a new world.; they were looking for spices.
Spices 引发了很多想象，给 14 到 16 世纪带来了各种发明，spices 可以用来制药、制造香水。所以对于 spices 的需求自然而然就增加了,导致哥伦布达伽马之流就开始寻找 spices。答案选 B。
Question 28：
Why does the professor say this:
A.To indicate that pepper was commonly used as payment
B.To indicate where pepper could be found at the time
C.To emphasize the high value of pepper at the time
D.To suggest that pepper was nearly as plentiful as gold
答案：C
解析：(原文中)Professor: Here is an example. In 408 AD, the Gothic General who captured Rome demanded payment. He wanted 5000 pounds of gold among other things but he also wanted 3000 pounds of pepper. Maybe that would give you an idea of exactly where pepper stood at the time.
Pepper 和金子能相提并论。从数量上看，pepper 的价值比金子有过之而无不及，说明 pepper 在当时的价值真的很高。
Lecture 4
Question 29：
What is the main purpose of the lecture?
A.To explain the biological advantages of a physical change that occurs in North American wood frogs
B.To explain why the North American good frog's habitat range has expanded
C.To describe the functioning of the circulatory system of the North American wood frog
D.To introduce students to an unusual phenomenon affecting North American wood frogs
答案：D
解析：该题是主旨题,比较简单，整个 lecture 都在说北美的 wood frog 有一种神奇的过冬现象，就是心跳停止了，但是它们还 alive。然后讲了下这种现象的原理以及这种现象的 effect。答案很清楚，选 D。
Question 30：
Why does the professor first mention the arrival of spring?
A.To encourage students to look for thawing wood frogs
B.To point out the time period when frogs begin mating
C.To explain why the class will soon be doing experiments with wood frogs
D.To emphasize the speed of the thawing process
答案：A
解析：(原文中)Professor: Well, it’s finally looking like spring is arriving. The last of the winter snow would be melting away in a few days. So before we close today, I thought I’d mention a biological event that’s a part of the transition from winter to spring, something you can go outside and watch if you have some patience. There is a small creature that lives in this area; you’ve probably seen it. It’s the North American wood frog.
教授说春天要来了，后文说道something you can go outside and watch if you have some patience，暗含着是鼓励学生在外面可以寻找到正在解冻的wood frogs。
Question 31：
What happens to a wood frog as it begins to freeze?
A.Blood is concentrated in the center of its body.
B.Blood stops producing sugar.
C.Water moves out of its internal organs.
D.Water from lust beneath the skin begins to evaporate.
答案：C
解析：(原文中)Professor: First touch of ice apparently triggers a biological response inside the frog. That first of all starts drawing water away from the center of its body, so the middle part of the frog, its internal organs, its heart, lungs, liver, these start getting drier and drier while the water that’s being pulled away is forming a puddle around the organs just underneath the skin.
当 wood frog 触碰到 ice 的时候，freeze 的活动正式开始。首先就是水分从内部器官中排出。很明显，答案选 C。
Question 32：
What are two points the professor makes about the thawing process of the wood frog?
Click on 2 answers.
A.The thawing process is not fully understood.
B.The thawing process takes longer than the freezing process.
C.The frog's internal organs thaw before its outer skin thaws.
D.Thawing occurs when the frog's heart begins pumping glucose through its body.
答案：AC
解析：(原文中)Student: Does the thawing process have some kind of trigger as well?
Professor: Well, we are not sure actually, the clearer thing is even though the sun is warning the frog up on the outside, its inside thaw out first, the heart and brain and everything.
教授的第一句话说明解冻的过程没有被完全理解，因为 professor说了 not sure。第二句话是Professor肯定的东西，那就是 wood frog 内部先解冻。因此答案选 A 和 C。
Question 33：
What impact does freezing have on some thawed wood frogs?
A.It increases their reproductive success.
B.It decreases their life span.
C.It causes them to be more vocal and active.
D.It reduces their ability to recognize potential mates.
答案：D
解析：(原文中)Professor: It does have some other impacts though. In studies, we found that when it comes to reproduction, freezing diminishes the mating performance of males.
教授说 freeze 的后果就是降低雄性 frog 的交配能力。和选项 D 意思一样。
Question 34：
What does the professor imply when she says this:
A.She wants the student to clarify his question.
B.She wants the student to draw his own conclusions.
C.She thinks the student does not understand how car antifreeze works.
D.She thinks the student has misunderstood her point.
答案：B
解析：(原文中)Student: A solution of antifreeze like you put in your car in the winter?
Professor: Well, you tell me. In frogs, the extra glucose makes it harder for the winter inside the cells to freeze. So the cells stay just slightly wet, enough so that they can survive the winter. Then after that, the heart stops beating altogether. So is that the same?
只凭 you tell me 并不能选出答案。Professor说了很多话，目的在于引导 student 区分 wood frog 的 antifreeze 的生理现象和 put the car in the winter 之间的区别。目的是根据她的提示，让学生得出conclusion。答案选 B。
