TPO3 listening 问题解析
注：问题中红色标记词汇为解题突破点和关键词
PART 1
Question 1：
Why does the woman come to the office?
A. To notify the university of her change of address
B. To find out where her physics class is being held
C. To get directions to the science building
D. To complain about her physics class being canceled
答案：B
解析：(原文中)Excuse me, I’m supposed to be having my physics class in the science building,but no one’s in the classroom. Could you tell me where the class is? Physics 403 — has it been moved?这个疑问句清晰的体现了学生来咨询的意图，就是为了 find out 她的物理课是在哪里上，这个 B 选项符合原文直接贴合。C 选项是一个无关选项，因为从句中明显体现出她已经到过 Science building 且发现无人在教室所以可以最先排除。
显然这时她还不知道物理课是被 cancle 了所以 D 排除，这时她也完全没有意识到学校的联络没有更新地址，这是之后的内容，因此 A 排除。
Question 2:
What happened to the letter the university sent to the woman?
A.She threw it away by mistake.
B.Her roommate forgot to give it to her.
C.It was sent to her old mailing address.
D.It was sent to another student by mistake.
答案：C
解析：(原文中)Ok, hmmm…Woodhouse, let me see… ah, it says here we sent it to your apartment on er… Center Street.
Student :Oh, that’s my old apartment. I moved out of there a little while ago.
在这两句对话中清晰的体现出 letter 被 send 到了 old apartment 也就是答案中的 old mailing address。 A选项的内容.在对话中有提及：I wonder if I threw it away with all the junk mail by mistake. 但是I 从 wonder if… 中体现出这只是猜测而非事实是虚拟语气，说明这只是猜测而非事实。 B，D 两个选项都是未提及，。只是从主观上有可能成为没有收到信件的可能原因但与对话无关。因此本题选C。
Question3
Why was the woman's physics class canceled?
A.Not enough students signed up to take the class.
B.No professors were available to teach the class.
C.The university changed its requirements for physics students.
D.There were no classrooms available in the science building at that hour.
答案：A
解析：(原文中)
Student :Yeah, I guess that’s it. But how can they cancel the class after offering it. If I’d known this was going to happen, I would have taken it last semester.
Receptionist :if we don’t have enough students sign up for the course, the college can’t offer it. You know, it’s a practical issue, like we can’t have an instructor when there’re only a few students in the class. You see what I mean?
从这一组问答中明确指出了问题中的题干，为何要 cancle class 而工作人员的回答也是十分直截了当，就是 don’t have enough students。C，D 为无关选项，那么 professor 有提到，但并不是因为老师的问题 You know, it’s a practical issue, like we can’t have an instructor when there’re only a few students in the class. 而是学校不会把师资用到只有几个学生的课上。一次，可见只给几名学生上课，依然是学生人数的问题。
Question 4
What does the man suggest the woman do before the beginning of next semester?
A.Consult with her advisor about her class schedule
B.Check with the registrar’s office about the location of the class
C.Register for her classes early
D.Call the physics department
答案： D
解析：(原文中)But do you know what you should do? Give the physics department a call a couple of weeks before the semester starts. They’ll be able to tell you if they’re planning to go through with it. It's their decision, actually. 以 But 开头的这个问句起就是提示作用，告诉我们这个工作人员即将告诉这个 student 该怎么解决这个问题。A， B, C 选项都是未提及。只提到要这个 student 修改地址而不是 class location。
Question 5
What does the man imply when he says this:
A.He knows the physics class has been canceled.
B.He is not sure where the science building is.
C.Many of the room assignments have been changed.
D.The woman can check for herself where her class is.
答案：D
解析：一开始工作人员并不知道 student 的具体情况只是以为她找不到教室，那么他说 Well, there’s a room assignment sheet on the bulletin board outside this office. 就是告诉这个学生你可以自己去这个 board 上看也就是 D 选项的意思。A，显然是错误选项，在查询电脑前，他并不知道这个课程的情况。B,C 原文中未提及。
Question 6
What does the professor mainly discuss?
A.Major changes in the migratory patterns of hummingbirds
B.The adaptation of hummingbirds to urban environments
C. Concern about the reduction of hummingbird habitat
D. The impact of ecotourism on hummingbird populations
答案：C
解析：Now, we’ve been talking about the loss of animal habitat from housing developments, uh …, growing cities – small habitat losses. But today I wanna begin talking about what happens when habitat is reduced across a large area. So what’s the impact of habitat loss on those animals – animals that need large areas of habitat? But 后的内容才是今天的主题。B 选项与文中事实不符。A 选项看似迷惑但是它的重点在 impact 和 habitat loss 导致它们数量减少，而不是 change in the migratory patterns。听力中虽然有提到 migratory 但是只是为了解释它在迁移途中需要消耗大量能量，而不是讨论它们迁移路线的变化。
Question 7
What does the professor imply might cause a decrease in the hummingbird population?
A.An increase in the ecotourism industry
B.An increase in the use of land to raise crops and cattle
C.A decrease in banding studies
D.A decrease in the distance traveled during migration
答案：B
(原文中)But the problem, well, as natural habitat along these migration routes is developed by humans for housing or agriculture or cleared for raising cattle, for instance, there is less food available for migrating humming birds.
这句中有清晰的指代出人类农业发展和 cattle 是导致栖息地以及蜂鸟数量减少的主因，因此B项是正确答案。A 项是与事实相反，ecotourism industry 的目的就是为了帮助保护蜂鸟。C项, banding studies 对蜂鸟数量不会造成影响。 D 项中 migration 的距离在教授的讲话中体现出没有减少。
Question 8
What does the professor say people have done to help hummingbirds survive?
A.They have built a series of hummingbird feeding stations.
B.They have supported new laws that punish polluters of wildlife habitats.
C.They have replanted native flowers in once polluted areas.
D.They have learned to identify various hummingbird species.
答案：C
解析: (原文中) So help them survive, we need to preserve their habitats. And one of the concrete ways people have been doing this is by cleaning up polluted habitat areas and then replanting flowers, um, replanting native flowers that humming birds feed on.
从红色字体部分显而易见是教授提到的要如何帮助蜂鸟生存下去的办法，也就是 C 选项中的内容。A，B 没有提及，D 项并不能帮助蜂鸟存活。
Question 9
What way of collecting information about migrating hummingbirds does the professor mention?
A.Receiving radio signals from electronic tracking devices
B.Being contacted by people who recapture banded birds
C.Counting the birds that return to the same region every year
D.Comparing old and young birds' migration routes
答案:B
(原文中)…oh, and there is a phone number on the band for people to call for free, to report a banded bird to be found or recaptured. So when a banded bird is recaptured and reported, we learn …这句在理解之后可以得出的信息是在 band 上有免费电话让找到蜂鸟的人拨打，并告诉研究人员他们所观察到的信息。 那么在归纳后发现是答案 B 中的内容。A 中的 radio signals 不能用来 tracking。C 在文中没有提及，D 并不能让研究者得到有关具体蜂鸟的数据。
Question 10
What does the professor imply researchers have learned while studying hummingbird migration?
A.Hummingbirds have totally disappeared from some countries due to recent habitat destruction.
B.Programs to replant flowers native to hummingbird habitats are ot succeeding.
C.Some groups of hummingbirds have changed their migration patterns.
D.Some plant species pollinated by hummingbirds have become extinct.
答案：C
解析：(原文中)Another interesting thing we learned is that some humming birds no longer use a certain route. They travel by a different route to reach their destination.虽然 professor 针对收集的信息罗列了的一大段话，但是只有这句是和蜂鸟迁移路线直接相关的。从 no longer use a certain route 看出蜂鸟改变了它们的迁移路线。A.B.D 都未提及。
Question 11
What does the professor imply when she says this:
A.There is disagreement about the idea she has presented
B.She does not plan to discuss all the details.
C.Her next point may seem to contradict what she has just said.
D.The point she will make next should be obvious to the students
答案：D
解析：It goesse without saying 体现出 professor 充分相信她接下来要讲的内容对于学生来说是十分明确的。 那么显然她不是要纠正或否定之前的的 idea，也并不是说明她不打算说细节，她在接下来的陈述称述中就讨论了细节。
Question 12
What is the main purpose of the lecture?
A.To discuss the style of an early filmmaker
B.To describe different types of filmmaking in the 1930s
C.To discuss the emergence of the documentary film
D.To describe Painleve’s influence on today's science-fiction films
答案：A
解析：(原文中)Today we are going to talk about a film-maker who began making very unique films in the late 1920s.在 Today 之前的一大段内容 Professor 都是在 review 上节课的内容，而从 today 之后的一句话则是今天这节课的重点，也就是 main purpose。A，D 是以偏概全以偏盖全，要讨论的不只是 Painleve’s influence 或者他的风格。C 为无关选项，文中的重点并不是纪录片的出现。
Question13
Why are Painleve’s films typical of the films of the 1920s and 1930s?
A.They do not have sound.
B.They are filmed underwater.
C.They are easy to understand.
D.They are difficult to categorize.
答案：D
解析：(原文中)Now in a way, Painlevé’s films conform to norms of the 20s and 30s, that is, they don’t fit very neatly into the categories we use to classify films today. That said, even by the standards of the 20s and 30s, Painlevé’s films were unique, a hybrid of styles.从本句描述出看出，PainlevéP 的电影风格无论在当时或现在都独特且是一种混合的风格，无法归类。A 是无声电影时代共同的特点;， B 的话也有其他人拍摄水下电影且可以归类为记录片; C 与事实相反，Painlevé P 的电影难以理解。
Question 14
According to the professor, how did Painleve's films confuse the audience?
A.They show animals out of their natural habitat.
B.They depict animals as having both human and animal characteristics.
C.The narration is scientific and difficult to understand.
D.The audiences of the 1920s and 1930s were not used to films shot underwater.
答案：B
解析：(原文中)His films begin with facts, but then they become more and more fictional. They gradually add more and more fictional elements.(提示句，从这之后开始描述为何Painlevé P 的电影是 confusing) He liked to show small underwater creatures, displaying what seemed like familiar human characteristics – what we think of as unique to human. He confused his audience in the way he portrayed the animals he filmed, mixing up on notions of the categories of humans and animals.
A 与事实不符，依然在动物栖息地拍摄;，C 是文中提到的但并不能回答这个问题，而且他的电影是 start with scientific 内容，之后有变化;。D 在当时也有别的水下电影拍摄者。
Question 15
Why does the professor mention sea horses?
A.To explain that they were difficult to film in the 1930s
B.To point out that Cousteau made documentaries about them
C.To illustrate Painleve's fascination with unusual animals
D.To explain why Painleve's underwater films were not successful
答案：C
解析：(原文中)He liked twists, he liked the unusual. In fact, one of his favorite sea animals was the seahorse because with seahorses, it’s the male that carries the eggs, and he thought that was great. His first and most celebrated underwater film is about the seahorse.
首先说Painlevé P 喜欢与众不同的事物，然后说 one of his favorite sea animals was the seahorse。显然 seahourse 是一个体现他喜欢与众不同事物的例子。A,B,D 则不相关。
Question16
Why does the professor compare the film styles of Jacques Cousteau and Jean Painleve?
A.To explain how Painleve influenced Cousteau
B.To emphasize the uniqueness of Painleve's filming style
C.To emphasize the artistic value of Cousteau's documentary films
D.To demonstrate the superiority of Painleve's filmmaking equipment
答案：B
解析：(原文中)He set the standard really for the nature documentary. Painlevé, on the other hand, as we said before, mixed in elements of fiction. And his films are much more artistic, incorporating music as an important element.一系列的比较就是为了体现出Painlevé P 的风格是独特的，与众不同的。C 以偏概全以偏盖全 artistic value 是PainlevéP 特色的一部分。D 错误，文中强调的是 Cousteau 的设备。A 未提及。
Question 17
What does the student imply when he says this:
A.He does not like Jean Painleve's films.
B.He thinks that the professor should spend more time discussing Jacques Cousteau's films.
C.He believes that high quality filmmakers are usually well known.
D.He believes that Jean Painleve's films have been unfairly overlooked.
答案：C
解析：(原文中)
Uh, the short answer is that Painlevé’s style just never caught on with the public. I mean, it probably goes back at least in part to where we mentioned earlier, that people didn’t know what to make of his films – they were confused by them, whereas Cousteau’s documentaries were very straightforward, met people’s expectations more than Painlevé’s films did. But you are true: film history is about what we know about them. And Painlevé is still highly respected in many circles.从教授之后的回答中可以体现出学生对Painlevé P 的质疑来自于 PainlevéP 没有 Cousteau C 那样的名气，这反映出学生认为相信优秀的电影人应该是知名的。A 过于主观，显然学生是不了解而不是不喜欢。B,D 未提及。
PART2
Question1
Why does the student go to see the professor?
A.To ask about a class assignment
B.To find out about a midsemester project
C.To get information about summer jobs
D.To discuss ways to improve his grade
答案：B
解析：(原文中)Hi, Professor Archure, you know how in class last week you said you were looking for students who are interested in volunteering for your archeology project? 第一个问句就说明了学生去找 preofessor 的目的。A,C,D 未提及。
Question2
What was originally located on the site of the lecture hall?
A.A farmhouse
B. A pottery factory
C.A clothing store
D.A bottle-manufacturing plant
答案：A
解析：(原文中)Well, as you know, we're studying the history of the campus this semester. This used to be an agricultural area and we already know that where the main lecture hall now stands, there once were farm house and barn that were erected in the late 1700s. 从此句中得出 lecture hall 的前身是个 farm house.
Question 3
What is mentioned as an advantage of working on this project?
A.Off-campus travel is paid for.
B.Students can leave class early.
C.The location is convenient.
D. It fulfills a graduation requirement.
答案：C
解析：(原文中)Wow, and it’s all right here on campus.
Professor :That’s right, no traveling involved. I wouldn't expect volunteers to travel to a site, especially in the middle of the semester.
从学生语气和老师之后的陈述中称述可以看出，这个项目很方便的一点就是它就在校园里，不需要没有traveling， 所以选是 C。D 不算 advantage。A,B 为无关选项。
Question 4
What is the professor considering doing to get more volunteers?
A.Offering extra class credit
B.Paying the students for their time
C.Asking for student volunteers from outside her class
D.Providing flexible work schedules
答案：A
解析：(原文中)there er… is there any way I can use the experience to get some extra credit in class? Actually I’ve been considering offering extra credit for class because I’ve been having a tough time getting volunteers. Extra credit is always a good incentive for students. 在男生提问后，接下来 教授Pro 的回答就是本题的答案。显然 BCD 都未提及。
Question5
What information does the student still need to get from the professor?
A.The name of the senior researcher
B.What book he needs to read before the next lecture
C.When the training session will be scheduled
D.Where the project is located
答案：C
解析：(原文中)Professor :Yes, er… I want to wait still Friday to see how many students volunteer, and then I’ll schedule the training class next week at a time that’s convenient for everyone.
Student :Ok. I’ll wait to hear from you. Thanks a lot for accepting me.从对话结尾的一组问答处可以听出 Professor 还没有确定 training session 的时间，因此这是 student仍旧需要知道的。 D 项在 conversation 前部分 professor 就回答过了。
Question 6
What does the professor mainly discuss?
A.The oldest known cave art
B. How ancient cave art is dated
C.The homes of Paleolithic humans
D.How Paleolithic humans thought about animals
答案：A
解析：(原文中)Some of the world’s oldest preserved art is the cave art of Europe, most of it in Spain and France. And the earliest cave paintings found to date are those of the Chauvet Cave in France discovered in 1994.Pro 的第一句话就揭示了他这节课的主题是 ealiest cave 也就是 A 选项中的同义转换。B 有些迷惑，虽然描述了 cave art 的 date 但是并没有说如何确定时期。
Question 7
Why does the professor mention his daughter?
A.To describe her reaction to seeing the paintings
B.To explain the universal appeal of the Chauvet paintings
C.To demonstrate the size of most Paleolithic cave art
D.To emphasize his point about the age of the Chauvet paintings
答案：D
解析：(原文中)And you know, I remember when I heard about the results of the dating of the Chauvet paintings, I said to my wife, “Can you believe these paintings are over 30,000 years old?” And my 3-yearold daughter piped up and said, “Is that older than my great-grandmother?”That was the oldest age she knew.那么从Professor pro 描述他听到 dating 的消息以及家人的反映可以看出，这是为了体现这 cave painting 的年代久远。B 中，他的家人并不能代表 universal appeal。
Question 8
What is the professor's opinion about the art at the Chauvet cave?
A.It is extremely well done.
B. It probably reflected the artists' religious beliefs.
C. It is less sophisticated than the art at Lascaux and Altamira.
D. It is probably not much older than the art at Lascaux and Altamir
答案：A
解析：(原文中)I mean, we tend to think that people who lived at that time must have been pretty primitive. But I’m gonna show you some slides in a few minutes and I think you will agree with me that this art is anything but primitive. They are masterpieces. ProfessorPro 先说人们对于那时的人的映像是十分原始的，从 but 后转折的内容 anything but primitive. They are masterpieces. 可以看出Professor PRO 给予了极高的肯定，也就是 It is extremely well done. C，D中的对比在教授的陈述中并没有针对Chauvet cave 来进行。
Question 9[新增解析]
According to the professor, what is the significance of charcoal marks on the walls of the Chauvet cave?
A. They suggest that Paleolithic people cooked their food in the cave
B. They prove that people came to the cave long after the paintings were made
C. They show how much light the Paleolithic artists needed for their work
D. They were used in recent times to date the paintings
答案：B
解析：(原文中)And each time you’d have to bring along torches to light your way. And people did go see the art. There are charcoal marks from their torches on the cave walls clearly dating from thousands of years after the paintings were made. So we can tell people went there. They came but they didn’t stay. 墙上的charcoal marks是人们举着火炬进来观看壁画留下的痕迹，这些痕迹证明了在壁画完成很久后，有人进了山洞，但是并没有停留特别长的时间。因此正确答案为B。
Question 10
Compared to other Paleolithic art, what is unusual about the animals painted at Chauvet?
A.Most of them are horses
B.Many of them are dangerous
C.Many of them are shown alongside humans
D.All of them are species that are still found in France
答案：B
解析：(原文中)Paleolithic cave art depicts large herbivores. Horses are most common overall with deer and bison pretty common too, probably animals they hunted. But earlier at Chauvet, there is a significant interest in large dangerous animals, lots of rhinoceros, lions, mammoth, bears. 本题做题时需要注意区分哪些是Paleolithic cave壁画的特征，哪些是Chauvet cave 壁画的特征。Paleolithic cave壁画中的动物通常是人们的猎物，比如马，鹿，牛等;Chauvet cave 壁画中的动物通常是对人们生存有威胁的动物，比如犀牛，狮子等。因此本题答案应选B。AC项是Paleolithic cave壁画的特征，D项未提及。
Question 11
What are two questions about the Chauvet cave artists that the professor raises but cannot answer? Choice two answers below
A. How they lighted their work area
B. How they obtained pigments for their paints
C. Why they chose to paint certain animals and not others
D. Why they placed their art in dark, uninhabited places
答案：CD
解析：(原文中)出处一：Deep inside a cave like that is not really a place you’d want to stay, so, why? What inspired the Paleolithic artists to make such beautiful art in such inaccessible places? We’ll never really know of course, though it’s interesting to speculate.
出处二：So, why these precise animals? Why not birds, fish, snakes? Was it for their religion, magic or sheer beauty? We don’t know. 本题需要对全篇讲座内容进行整体把握。教授在两个地方提到了“We don’t know”,一个是在cave的地点选择，为什么要把壁画画在人迹罕至的地方;另一个是壁画中的动物形象的选择，为什么选择哪几种特定的动物。因此正确答案是CD。
Question 12
What is the lecture mainly about?
A. Different ways of magnifying the spectrum of a star
B. How a chemical element was first discovered on the Sun
C. How astronomers identify the chemical elements in a star
D. Why the spectra of different stars are composed of different colors
答案：C
解析：(原文中)Now astronomy didn’t really bloom into the science it is today until the development of spectroscopy. Spectroscopy is basically the study of spectra and spectral lines of light, and specifically for us, the light from stars. It makes it possible to analyze the light emitted from stars. 教授一开始便说了今天讲座的主题是spectroscopy 光谱学，并且通过“astronomy didn’t really bloom into the science”说明了今天讲座主要是讲光谱学在天文学方面的应用。因此正确答案是C。
Question 13
What does the professor explain to one of the students about the term “radiation”?
A. It is defined incorrectly in the textbooks
B. It was first used in the nineteenth century
C. It is rarely used by astronomers
D. It does not refer only to harmful energy
答案：D
解析：(原文中)
Student: Optical radiation. But I thought being exposed to radiation is dangerous.
Professor: Yes, and no. If you are talking about radiation, like in the element Uranium, yeah, that’s dangerous. But radiation as a general term actually refers to anything that spreads away from its source. So optical radiation is just visible light energy spreading out. 学生认为所有的radiation都是危险的，教授对他的观点进行说明，解释了radiation的字典释义是“a general term actually refers to anything that spreads away from its source”，所以radiation有的危险，有的不危险，主要是看是哪一类的辐射。因此正确答案选D。
Question 14
What can be inferred about two stars if their spectra have similar spectral line patterns?
A.The stars are approximately the same distance from the Earth
B.The stars probably have some chemical elements in common
C.The stars have nearly the same brightness
D.The stars are probably of the same size
答案：B
解析：(原文中)But the spectral lines would break it up at different places, and different patterns. Each pattern stands for a distinct chemical element, and so different sets or patterns of spectral lines mean that the star has a different chemical composition. 根据原文反推，不同的patterns of spectral lines说明有不同的chemical composition，那么相同的spectral line patterns呢?答案自然是选B。
Question 15
According to the professor, what is the purpose of heating an element in a spectroscopic flame test?
A. To cause an element to emit light
B. To study an element in combination with other elements
C. To remove impurities from the element
D. To measure an element’s resistance to heat
答案：A
解析：(原文中)a kind of spectroscopic library of elements was compiled using flame tests. A known element, say a piece of iron for example, is heated in a pure gas flame. The iron eventually heats to the point that it radiates light. 教授举了在flame tests中给铁加热的例子，持续给铁加热，直到铁发射出光。说明给element加热的原因是为了让铁emit light。正确答案选A。
Question 16
Why does the professor say this?
A. He is about to provide some background information
B. He is about to repeat what he just said
C. He intends to focus on the history of astronomy
D. He intends to explain two different points of view
答案：A
解析：(原文中)Before we get into that though, it’s probably a good thing to back up a bit. You all know how when you take a crystal prism and pass a beam of sunlight through it, you get a spectrum, which looks like a continuous band of rainbow colors. 重听题。教授在介绍完Spectroscopy之后，紧接着说了重听部分的那句话：“Before we get into that though, it’s probably a good thing to back up a bit.”然后开始讲光谱的由来。因此可以推断出，教授这句话的目的是为了引出后面的光谱学背景知识介绍。
Question 17
Why does the professor ask this?
A. To check the students’ understanding of their reading assignment
B. To give the students a hint to the answer to his previous question
C. To emphasize how important it is for astronomers to study Greek
D. To remind the students about the historical background of astronomy
答案：B
解析：Professor: Any guesses about what that element is? It actually turned out to be pretty common and I’m sure all of you know it. OK. Let’s try something else. Any of you happened to be familiar with the Greek word for “sun” by chance?
Student: Something like “Helius” or something like that. Oh it must be “Helium”. So you are saying that Helium was discovered on the sun first.
教授先问了学生一个问题“Any guesses about what that element is?”但是学生回答不出来，所以教授就说了重听部分的那句话“Any of you happened to be familiar with the Greek word for “sun” by chance?”作为提示。后面学生根据教授的提示回答出了之前教授的提问，更说明了教授重听部分说的话是为了提示学生之前问题的答案。因此选B。
