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：(原文中)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，并且也有停顿。原因是女生在网上发布了一个通知，但是在学校网页上没有这个通知。所以C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：(原文中)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她们承诺了他可以去很多人，她对于这个承诺很有信心，因为她知道学生们都很有热情。所以A项正确。
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：(原文中)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?
然后这个男的说到 well，答案就在这里。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…因此，答案选C。
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：(原文中)：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.
出现But 这样的提示词就意味着答案要出现了。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中的 more specialized website。
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：(原文中)：But the French Department is funding this.
前面那个男的问女生，你们举办这个活动有没有经过学校认证的部门呢?女生说没有，But the French Department is funding this.来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：(原文中)：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，因为大家的注意力应该全被后面的Antikythera Mechanism吸引走了。但是，它只为了举例子说明有哪些 archaeological find 挑战了大家的尝试，大家要提高警惕。
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：(原文中)：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.
Antikythera Mechanism是个挺小的装置，里面有好多齿轮，然后运转就能显示出太阳月亮的运动之类的。其实重点还是后面的 inside the box。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什么关系，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：(原文中)：Some of my colleagues insisted it had to have been made well after 100 B.C. But this physical evidence was conclusive. It was that old.
说到态度，some people的观点基本上是要被后面否定掉的。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Antikythera Mechanism是有那么古老的，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 material
答案：A
解析：(原文中)：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，说铜虽然不是很稀有，但是有价值而且容易被回收。所以答案就是 A 。
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：(原文中)：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 were 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：(原文中)：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地值得注意，就是这个机器特别准确，甚至使用它可以测量特别不规则的月球轨道。用了 but和强调句还有两个particular。说明这个机器比我们想象中的要先进，答案选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：(原文中)：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 landmasses 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：(原文中)：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.
教授其实说的就是一种平衡叫做 Earth’s radiation budget，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：(原文中)：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.
but转折后引出正确答案，就是为了说不同类型的云有不同的反射比例，因此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：(原文中)：Yep. And as I said earlier, this cooling effect predominates.
前面这教授说了很多，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。
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：(原文中)：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：(原文中)：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，觉得自己说不了那么多，结果说很多，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。

A. Parts of the dolphin’s anatomy that allow it to navigate
B. Two different types of communication used by dolphins
C. The way that dolphins store air while swimming underwater
D. The meanings of different signals used by dolphins
答案：A
解析：(原文中)：We have been talking about how sea animals find their way underwater, how they navigate, and this brings up an interesting puzzle, and one I'm sure you'll all enjoy. I mean, everybody loves dolphins, right?
听出开头之后，结合全文，这道题就不难理解了。B选项有一定的迷惑性，但是海豚的声音有一种是用来定位的，communication 错了。
24. Why does the professor discuss the speed at which sound travels?
A. To describe why sounds made under water can travel long distances
B. To show why a person cannot hear a dolphin well when it is under water
C. To compare the speed of two different sounds made by dolphins
D. To explain how sound waves behave when crossing from one medium into another
答案：D
解析：(原文中)：And the puzzle is how does the click sounds get transmitted into water. It's not as easy as it might seem. You see, the denser the medium, the faster sound travels. So sound travels faster through water than it does through air.
这段话中教授说到了声音了速度，也说到了不同的介质，所以可以推断出答案选D。
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
解析：(原文中)：If it's going to navigate it, needs those sounds to be broadcast and bounced back from objects in its path. Well, turns out dolphins have a structure in their foreheads, just in front of their nasal sacs, called a melon. Now, the melon is kind of a large sac-like pouch, made up of fat tissue.
Well 是提示词，需要引起大家的注意，“called a melon”科学名词出现，后面必定要解释，解释就是出题点。well 前面那句又说他们需要把这些声波散播出去，所以选 B。
26. What is the dolphin's jaw able to do?
A. Send rapid clicking sounds into water
B. Increase the speed of sounds
C. Receive sound waves that have reflected off objects
D. Force water through the nasal sacs and out the blowhole
答案：C
解析：(原文中)：It turns out that the jaw is primarily responsible for capturing and transferring returning sound waves to the dolphin’s inner ear.
前面两句有一处教授停顿，并且有 the only…作为提示，然后这句话说下巴主要负责捕获反射回来的声波，所以就选 C 了。
27. How does the professor organize the information in the lecture?
A. By describing a phenomenon and the physical structures that make it possible
B. By describing several of the dolphin’s senses and their relative usefulness
C. By contrasting how the dolphin makes two different types of sounds
D. By describing an old theory and then a new theory
答案：A
解析：这道题需要把握全文。先说海豚可以发出两种声音，然后还引出了一个 puzzle 进行解释，从而说发出和接受声波的部位。所以选 A。
28. Why does the professor say this [one being the vocalizations you are probably all familiar with, which they emit through their blowholes.]
A. To find out whether students are familiar with the lecture topic
B. To mention a related topic that will not be discussed in detail
C. To mention a common misconception about dolphin vocalizations
D. To point out a primary function of dolphin blowholes

B. To emphasize that screen dancers should not be concerned about their facial expressions
C. To give an example of a weakness of modern choreography
D. To suggest a reason why dancers might want to participate in a screen dance
答案：D
解析：(原文中)：For example, dancers can express themselves, even change the whole mood of the scene through a facial expression.
听力原文中提到For example，这就是这道题的考点。前面又有同学说话，说我觉得 stage 上的表演才鼓舞我们，教授就得解释为什么还有人想在银幕上跳，所以就是 D。
31. How does the professor try to make students feel more confident about their assignment?
Click on 2 answers
A. He tells them they will be able to practice editing films.
B. He tells them that technical assistance is available if they need it
