Conversation 1
1. What is the cause of the student's problem?
A．She missed the deadline for submitting her announcement to the university web site
B. She did not include enough information in her announcement.
C. The editors of the university web site did not post her announcement
D. The university web site will not be available to students for several days.
答案：C
解析：（08”）定位句：I'm here 'cause... well,there's something I don't understand. I set an announcement for an event. And this morning I checked the events section of the university's website. And nothing, there is no mention of it.
听清开头就会发现，有很明显的提示词cause，还停顿了。原因就是女生在网上发布了一个通知，但是在学校网页上木有这个通知。C选项正确
2. What did the student's group have to promise the author in order to get him to visit the university?
A. That he would have a large audience for his reading
B. That his books would be advertised on the university web site
C. That the French Department would pay his travel expenses
D. That he would also be able to speak at another nearby university
答案：A
解析：（52”）定位句：We were able to sell him on the idea by promising there’ll be a nice size crowd, I felt confident about that, because I know how enthusiastic our group is.
女生说作者能来是因为承诺了他可以去很多人，因为学生们都很有热情。所以就A正确
3. What does the man imply about the editors of the university' web site?
A. They are sometimes careless in their handling of students.
B. They sometimes revise students’ announcements before posting them.
C. They routinely try to predict student interest in upcoming events.
D. They usually attend the events advertised on the web site.
答案：C
解析：（1’44”）定位句：Well, we don't post things automatically. We get so many requests that we couldn't possibly post them all. So events that are thought to be too specialized, without the potential for really wide appeal...
前面女生问了个特明显的Why？然后这个男的well，答案开始了！男的说他们做筛选工作不是自动的，而是人工的，所以他人为这个活动不太可能受到广泛的欢迎…C就正确了。
4. What does the man suggest the student do?
A. Postpone the event until next week
B. Advertise the event on a more specialized web site
C. Explain her situation to the editors of the university web site
D. Create a poster to advertise the event
答案：B
解析：（2’20”）定位句：But maybe you could ask the French department to post the announcement on its website. And maybe you could approach some other departments as well, you know, relevant ones.
But这么明显的提示词就是说答案要出现了！男的说你可以要求法语部或者其他相关部门帮你们贴活动通知，就是B种的more specialized website，A可能成为迷惑选项，因为在But 之前还balabala说了一堆什么schedule已经排到下个星期了，但是听到But之后就全都抛弃吧，B是正确的
5. Why does the student say this [But the French Department is funding this]
A. To suggest that the man contact the French Department
B. To express her frustration with the French Department's requirements for funding
C. To assure the man that the event has the support of the French Department
D. To explain why she is asking the man for additional funding
答案：C
解析：（1’24”）定位句：But the French Department is funding this
前面那个男的问女生你们有木有经过学校认证的部门来举办这活动呀？女生说木有，男的很鄙视说O~K~。所以这女的急了来了一句这个，是说明他们还是有部门支持他们的活动的，是可以举办的！所以C选项是正确的
Lecture 1
6. What is the lecture mainly about?
A. The methods archaeologists used to reconstruct the Antikythera Mechanism
B. The influence the Antikythera Mechanism has had on the study of physics
C. A research project in the combined fields of archaeology, physics, and mathematics
D. An archaeological discovery that challenged an accepted historical view
答案：D
解析：（20”）定位句：At any rates, that conversation got me thinking about archaeological finds that really changed our understanding of ancient civilizations.
这道题的迷惑性很强啊，因为大家的注意力应该全被后面那个AM的东西吸引走了。但是！AM那东西只为了举例子说明有哪些archaeological find挑战了大家的尝试，大家提高警惕啊！
7. According to the professor, how did the Antikythera Mechanism work?
A. Dials on the device could be turned to calculate a ship's location at sea
B. The device was used to operate a larger computing system
C. A system of gears rotated the images located on the case
D. Light from the Sun illuminated particular indicators on the case throughout the day
答案：C
解析：（56”）定位句：The Antikythera Mechanism is a relatively small device, roughly the size of a shoebox, made of gears fitted inside a wooden case. In its original state, there were rotating dials and other indicators on the top, with letters and drawings showing the Sun, the phases of the moon and different constellations. Inside the box, bronze gears would have rotated the displays. The displays, uh, the indicators of the Antikythera Mechanism, would then move to show the motion of the Sun and moon relative to the planets and stars.
教授在主旨句之后又说了点废话，好不容易说了个but，结果后面的内容并不是很重要。突然，一个停顿出现了！！！答案来了！虽然有点长吧，但是必须得听懂，总之就是这个AM是个挺小的装置，里面有好多齿轮，然后转啊转啊转就能显示出太阳啦月亮啊的运动啥的。其实重点还是后面的inside the box，听懂了就好。A具有一定的迷惑性，但是这段话完全没提到跟船的位置有啥关系，所以就是C是正确的。
8. What is the professor’s attitude about the proposition that the Antikythera Mechanism is over two thousand years old?
A. She is confident that the dating is accurate.
B. She is sure the dating will be revised in the future.
C. She is surprised that the dating remains inconclusive.
D. She believes that additional testing will be needed to confirm the dating
答案：A
解析：（2’13”）定位句：Some of my colleagues insisted it had to have been made well after 100 B.C.E. But this physical evidence was conclusive. It was that old.
说道态度，some 这群人的观点基本上是要被后面否定掉的。大家作文里面也会写，some people hold that…but in my opinion…吧~就是这个道理！
教授在后面说了一个but，又用强调语气说了一遍It was that old.说明教授是觉得这个AM有那么古老的，选A
9. According to the professor, why is it unusual to discover a bronze artifact from ancient Greece?
A. Bronze objects were often recycled.
B. Bronze corrodes underwater very quickly
C. Ancient Greeks had limited access to bronze
D. Artists of ancient Greece preferred to work with other materials
答案：A
解析：（2’25”）定位句：Of course part of what made this find so unusual is that the Antikythera Mechanism is constructed of bronze. Now, it is not that bronze was all that rare in Greece then, it is just that bronze was valuable and could easily be recycled.
Of course引出了一个强调句，然后答案就在后面跟着呢！说铜虽然不是很稀有，但是有价值而且容易被回收！所以就是A了。
10. How were archaeologists able to determine how the Antikythera Mechanism operated?
A. By comparing it to similar devices used 1,000 years later
B. By using gamma rays to see inside of the mechanism
C. By referring to ancient Greek writings about the mechanism
D. By consulting with colleagues in the field of physics
答案：B
解析：（3’31”）定位句：We could only get a good look at the structure of the gears after gamma-rays were used to see inside, very similar to the way X-rays are used to see your bones.
教授的only说的很清楚，然后说只能通过gamma射线才能看清楚内部结构，就选B。
11. What does the professor imply about the ancient Greeks when she says this [But one thing that is particularly notable is that the mechanism was so precise that it even took into account a particular irregularity in the moon's orbit, which requires some very complex math to replicate in mechanical device.]
A. They w ere the first to observe the irregularly in the Moon’s orbit.
B. They might not have been the inventors of the Antikythera Mechanism
C. They were more scientifically advanced than is commonly thought.
D. They appeared to have made some errors in their calculations.
答案：C
解析：（4’05”）定位句：But one thing that is particularly notable is that the mechanism was so precise that it even took into account a particular irregularity in the moon's orbit, which requires some very complex math to replicate in mechanical device.
教授说有一件事特别的值得注意，就是这个机器特准确，即使用它测量特别不规则的月球轨道。用了but，和强调句，还有particular用了两遍。说明就是比咱们想象中的要先进，选C
Lecture 2
12. What is the lecture mainly about?
A. Ways of identifying different types of clouds
B. Recent research findings about the causes of global warming
C. The impact of clouds on global temperatures
D. The impact of human activity on cloud formation
答案：C
解析：（06”）定位句：Basically, a cloud either contributes to the cooling of Earth's surface or to its heating.
教授开门见山，Basically进行提示，说云既给地球表面降温，又给地球表面升温，再结合后面的全文，选出C选项并不困难
13. According to the professor, what is Earth’s radiation budget?
A. The average temperature difference between land masses and bodies of water
B. The balance between incoming solar energy and reflected solar energy
C. The percentage of incoming solar energy that gets trapped in clouds
D. The portion of marine species that has been affected by global warming
答案：B
解析：（26”）定位句：And this balance between the amount of solar radiation, energy from the Sun, that's absorbed by Earth, and the amount that's reflected back into space. We call this Earth's radiation budget.
其实从教授不停的说balance开始，大家就要注意了，然后终于开始解释这个balance，必须是出题点了。其实说的就是一种平衡就叫做Earth’s radiation budget，就选择B。
14. Why does the professor discuss albedo?
A. To point out that different surfaces have different reflective properties
B. To suggest that the reflective surfaces on Earth should be increased
C. To demonstrate how a cloud's thickness is measured
D. To explain why clear air reflects a large amount of solar energy back to space
答案：A
解析：（1’32”）定位句：OK. Now, when we say that clouds have a high albedo, we are talking about the effect of all the clouds on earth averaged together. But different types of clouds have different reflective properties, they have different albedos.
前面的OK，Now是引起大家的强烈注意啊，然后出来一个BUT，说明后面的就是答案了。没啥说的，albedo说了一堆，就是为了说不同类型的云有不同的反射比例，A正确
15. What can be inferred from the lecture about the effects of different types of clouds on Earth's climate?
A. Low, thick clouds increase ocean temperatures much more than high, thin clouds do
B. The cooling effect of low, thick clouds is stronger overall than the heating effect of high, thin clouds
C. The effect of low, thick clouds is understood better than the effect of high, thin clouds.
D. The effect of low, thick clouds is much more variable than the effect of high, thin clouds.
答案：B
解析：（2’37”）定位句：Yep. And as I said earlier, this cooling effect predominates.
前面这教授说了一堆，其实主要就是要介绍低的厚的云是cool the earth的，高的薄的云是heat的。这是一段问答，是出题点，之前还说了一句：低的云会把大部分的能量反射回去，再加上这句cooling effect是predominate（占优势），所以B就可以推断出来了。这道题有一定的难度，因为需要自己把两种云heat和cooling的关系进行推断，不是文中明确说明的，需要大家注意一下
16. What does the professor say about microscopic plants in the ocean near Antarctica?
A. They have been raising the ocean's albedo.
B. Their population is increasing due to global warming.
C. They grow more rapidly when cloud cover is thin.
D. They produce a chemical that leads to cloud formation
答案：D
解析：（3’17”）定位句：Well, the current hypothesis is that these microorganisms produce a chemical, dimetho-sulfide that interacts with the oxygen in the air, creating conditions that lead to the formation of the low thick clouds we observed.
这道题，教授的重点强调的很明显，在前面一句的结尾，特地重读，这一句的chemical也强调出来了。是这种化学物质与空气中的氧发生反应，创造出来的条件导致了低厚的云的形成。选择D
17. Why does the professor say this [So, maybe we are talking about controlling the weather.]
A. To reintroduce a topic from a previous lecture
B. To correct a common misunderstanding
C. To encourage students to express their own opinions
D. To revise his previous response to a student's question
答案：D
解析：（3’35”）定位句：So, maybe we are talking about controlling the weather.
之前学生问了一句“Are you talking about controlling the weather”教授说，我觉得我说不了那么多，结果自己blabla说一堆，发现正好回答了前面的问题，所以说了一句也许我们正在谈论控制天气。所以答案是D

19. Why did the professor assign "Araby" instead of another short story from Dubliners?
A. It is not related to the other stories in the collection.
B. It is the shortest story in the collection.
C. It is told from the narrator’s point of view.
D. It is organized in a predictable way.

25. What is the dolphin's melon?
A. An oval-shaped bone that lets the dolphin hear sounds
B. An organ made of fat tissue that helps a dolphin send sound waves
C. An air-filled cavity that lets the dolphin breathe underwater
D. An organ filled with water that helps the dolphin measure depth
答案：B
