  B.To give an example of the persistence of traditional theories

  C.To show that scientific knowledge is rarely influenced by philosophy

  D.To compare methods in observational and theoretical astronomy

  答案:B

  解析:(原文中)Professor: ... how throughout history, it was often difficult for people to give up ideas which have long been taken for granted as scientific truth, even if those ideas were false. In Astronomy, for example, the distinction between the solar system and the universe wasn’t clear until modern times.

  从以上这段话及全文可知,教授是在讲述一个例子,而例子要证明的正是一个 traditional theories.

  7.Why did the ancient Greeks hold the geocentric view of the universe? Click on 2 answers.

  A.The Sun appeared to them to revolve around Earth.

  B.They had not developed methods of gathering accurate data on the movement of planets.

  C.Their religious and philosophical beliefs supported this view.

  D.Some of the planets in the solar system had not been discovered yet.

  答案:AC

  解析:(原文中)Professor: ...Observations of the sky make it appear as if the Sun, the moon, and the stars all revolve around the Earth every day, while the Earth itself stayed in one place. And this view is also supported by their philosophical and religious beliefs about the origin and structure of the universe.

  教授很明确指出有两个原因:1. 从他们的观察中,太阳是围着地球转的 2. 他们所持的观点也得到 philosophical and religious beliefs 支持。

  8.Why does theprofessor point out that Greek astronomers tried to explainnew astronomical discoveries within the geocentric concept?

  A.To explain why early astronomers found new discoveries exciting

  B.To explain why some claims made by ancient Greek astronomers conflicted with claims made by earlier astronomers

  C.To illustrate that the geocentric concept was open to many interpretations

  D.To illustrate that the geocentric concept itself was not considered questionable

  答案:D

  解析:(原文中)Professor: ... Now, what’s especially interesting is that when astronomical observations were made that seemed to be inconsistent with the geocentric view, the ancient Greeks did not really consider alternative theories. It was so intuitive, so sensible that the Earth was the center of the universe that astronomers found ways to explain those seemingly inconsistent phenomena within the geocentric view.

  通过以上讲解可知,原因是即使astronomical observations与geocentric view不一致,ancient Greeks 并没有考虑其他可选择的理论。

  9.Why does the professor discuss the epicycle theory?

  A.To explain why early astronomers started measuring the velocity of the planets

  B.To explain why the astronomer Aristarchus rejected the geocentric model

  C.To show how early astronomers explained the apparent backward motion of some planets

  D.To show that early astronomers believed that all planets moved in their own orbits around the Sun

  答案:C

  解析:(原文中)Professor: ... However, astronomers noticed that at times, several planets seem to stop moving in one direction and start moving backward in their orbits around the Earth, and they came up with a theory that these planets themselves moved in smaller circles called epicycles as they travelled around the Earth.

  通过教授的讲解,epicycles theory 的出现是由于 early astronomers 为了解释 several planets start moving backward。

  10.In the professor's view, what might have caused Aristarchus to propose the heliocentric theory?

  A.The discovery that Earth was much smaller than the Sun

  B.The lack of proof supporting the theory of epicycles

  C.The influence of well-known philosophers

  D.The apparent stability of Earth

  答案:A

  解析:(原文中)Professor: ... Aristarchus recognized from his calculations that the Sun was much larger than the Earth and other planets. It was probably this discovery that led him to conclude that the universe is heliocentric.

  教授明确指出,可能是因为 Aristarchus 发现太阳要比地球大很多。

  11.What were two arguments ancient Greeks used to reject the heliocentric model? Click on 2 answers.

  A.More stars would be visible in a heliocentric universe.

  B.A moving Earth would create a strong wind.

  C.Aristarchus's calculations were inaccurate.

  D.Objects fall toward the center of the universe

  答案:BD

  解析:(原文中)Professor: ... Let me mention two objections Greeks made to Aristarchus’s theory. First, they believe that everything that moves creates its own wind. ... And second, the idea of an Earth that moved didn’t fit in with the ancient Greeks’ understanding of gravity. They thought that gravity was basically a natural tendency of all things to move towards the center of the universe,

  教授明确指出拒绝的原因有两个:1. 他们认为任何物体运动产生 wind 2. 他们认为物体下落应该朝向宇宙中心。

  Lecture 2

  12.What is the main purpose of the lecture?

  A.To describe some recent improvements in computer technology

  B.To explain why so many software products have flaws when they are put on the market

  B.It is based on an incident in which an insect interfered with the function of any early computer.

  C.It was first used by early computer scientists who noticed small problems in programming code.

  D.It was first used by developers who did not like testers identifying problems in their work.

  答案:B

  解析:(原文中)Professor: ... back in the 1940s, when the computer industry was just starting, a group of computer scientists was working late one night, and there was a problem in one of the computers’ circuits1. When they examined it, they found a five-centimeter long moth caught in there. Once they debugged the computer, it worked just fine. And ever since then, all kinds of computer problems have been known as bugs. 以上的讲解详细解释了 bug 一词被用作表示 computer problem 的来源。

  14.What points does the professor make about software developers? Click on 2 answers.

  A.The work they do is mainly creative.

  B.They enjoy the challenge of identifying problems to fix.

  C.Their work is easier than the work of software testers.

  D.They are not always able to detect software problems.

  答案:AD

  解析:(原文中)Professor: ...because developers often have a bias for their own work, and it blinds them to certain problems that might be obvious to somebody else. ... The mentality of the software developer is constructive, creative,theyare spending longhours workingtogether to create and build something new.

  教授指出,developer 1. is creative; 2. 因为他们自己码的代码,有时会导致他们发现不了问题。

  从对话可知,在 Project Unity 中,developer 和 tester 之间并未产生敌对的心理。

  16.How did the software product developed during Project Split differ from the product developed during Project Unity?

  A.The Project Split product was released to the market in a shorter amount of time.

  B.The Project Split product could be used in more types of computer systems.

  C.The Project Split product cost less money to develop.

  D.The Project Split product was of inferior quality.

  答案:D

  解析:(原文中)Professor: ...we ended up having to put the product on the market with known bugs in it, which was obviously not ideal.

  教授在谈到 Project Split 的结果时,表示最后不得不将存在已知 bugs 的产品投入市场,即产品质量是较差的。

  17.When the professor discusses some work meetings attended by two teams, why does he say this: (复听题)

  A.To emphasize the fact that to the teams were in conflict with on another

  B.To make the point that testers are just as important as developers

  C.To indicate that the teams had different ideas about how to market the new software

  D.To emphasize the importance of meetings in the development process

  答案:A

  Lecture 3

  23.What is the lecture mainly about?

  A.Methods of analyzing toxic proteins in snake venom

  B.Insights about snake evolution provided by venom analysis

  C.How snake venom differs from lizard venom

  D.Why colubrids are considered nonvenomous snakes

  答案:B

  解析:从全文来看,教授先提到蛇的分类,在提到一个关于蛇进化的新理论,接着讲述了一个实验是如何来证明这个理论的。

  24.Why does the professor review information about the classification of snakes that students probably learned in previous courses?

  A.To determine whether the students have enrolled in the appropriate course

  B.To stress the usefulness of the classification system for students

  C.To present assumptions that have recently been challenged

  D.To give an example of a method that she will explain in greater detail

  答案:C

  解析:(原文中)Professor: ... Then there is non-venomous snakes like constrictors and pythons. Another family of snakes, the colubrids, don’t really fit neatly into either category though. Colubrids, and you probably learned this too, although they are often classified as venomous snakes, they are actually generally non-venomous. They are classified as venomous snakes because they resemble them, their advanced features more than the other non-venomous snakes. Now, what if I told you that there is a good chance that most everything I just said is wrong?

  通过以上可知,教授提及以前可能学过的内容是为了引出一个会 challenge 这些内容的观点。

  25.According to the professor, what is a major weakness of the classification system that is based on animals' physical characteristics?

  A.It can show the relationships only among a small number of animal species.

  B.It requires technology that is not widely available.

  C.It cannot account for characteristics that first appeared in the recent geologic past.

  D.It cannot determine whether similar characteristics developed in similar ways.

  答案:D

  解析:(原文中)Professor: ... Traditionally, to understanding evolutionary relationships, we looked at various easily observed physical characteristics of animals, ... and then classify them based on similarities and differences.

  这里说的就是题目中问到得传统的根据外表特征分类。The problem with this method is that characteristics that appear similar may actually have developed in quite different ways. 这一句就说出了这种方法的weakness,就是题目中D说的这个意思。他们长得一样不一定进化的一样。

  26.According to the professor, in what way do colubrid snakes differ from other venomous snakes?

  A.Colubrids did not evolve from lizards.

  B.Colubrids do not use venom to catch their prey.

  C.The front teeth of colubrids are much larger than those of other venomous snakes.

  D.Colubrids produce a much stronger type of venom than other venomous snakes do.

  答案:B

  解析:(原文中)Professor: ... What separates colubrids from other snakes we have been classifying is venomous, is not the lack of venom, but the lack of an effective way to deliver the venom into its prey. In most venomous snakes, like vipers and cobras, the venom is used to catch and inmoblize the prey; but in colubrids, venom drips onto the prey only after the prey is in the snake’s mouth.

  根据以上讲解可知,区分的点在于不是用 venom 进行捕食。

  27.Why does the professor mention the brown tree snake?

  A.To support a hypothesis about the evolution of constrictor snakes

  B.To support a hypothesis that venomous snakes evolved from constrictor snakes

  C.To give an example of a snake species that was never venomous

  D.To give an example of a type of snake that can change its color

  答案:A

  解析:(原文中)Constrictors have evolved to kill their prey by crushing, but perhaps they once were venomous, and then at some point their venom-producing apparatus4 wasn’t needed anymore, so it gradually disappeared. There’s one species of snake, the brown tree snake, that uses both constriction and venom, depending on its prey. So, well, it is possible.

  教授在提到一个关于 constrictors 进化的假设时,提到了 the brown tree snake.

  28.What is the professor's attitude toward the results from medical research on snake venom proteins?

  A.She is enthusiastic about the drugs that have been tested to date.

  B.She is concerned about the side effects of drugs created from snake venom proteins.

  C.She doubts that the DNA database will be useful in developing new drugs.

  D.She thinks it is too early to tell how successful the research will be.

  答案:D

  解析:(原文中)Now, it sounds far-fetched, venom is the basis for human drugs. So far, only one protein has been targeted for study as a potential drug, but who knows, maybe someday.

  这表明她觉得一切都还太早的态度。

  Lecture 4

  29.What aspect of Alice Neel's work does the class mainly discuss?

  30.What point does the professor make about photographyand portraiture inthe twentieth century?

  A.Painters began to produce more lifelike portraits in imitation of photography.

  B.Photography largely replaced the tradition of portrait painting.

  C.Photographers followed the style of portrait painters in creating their work.

  D.Both photography and portrait painting were considered inferior art.

  答案:B

  解析:(原文中)Professor: ... After photography became regarded as an art form, portrait painting became less prestigious, less respected as an art form. And, well, art photography kind of took its place, so you can imagine that a portrait artist, would have had a hard time finding acceptance.

  从以上教授的讲解可看出,portrait painting 变得不再受尊重,而 art photography 在一定程度上取代了 portrait painting。

  31.According to the professor, what two aspects of Neel's work are characteristic of Expressionism? Click on 2 answers.

  A.The depiction of unusual object

  B.The way the subjects' faces are portrayed

  C.The shape of the subjects' bodies

  D.The use of color in the paintings

  答案:CD

  解析:(原文中)Professor: ...First, Neel’s use of bold color. All right? You’ll see she uses color to convey emotion and feeling, like the subjects’ clothing for instance, it appears brighter than it really is. And the subjects, the people being portrayed, Neel paid special attention to faces. The way she paints the eyes and how the faces are portrayed, these are quite realistic, like the realists’ work. But another thing Neel did was use elongated, sort of stretchy figures.

  可以看出特点分别是use of color和elongated, sort of stretchy figures。

  32.According to the professor, why did Neel paint portraits?

  A.She felts that it was the best way to represent a time period.

  B.She enjoyed the technical challenge of painting portraits.

  C.She found that it was too difficult to earn a living painting abstract art.

  D.She followed the lead of Expressionist painters who also painted portraits.

  答案:A

  教授提出,Neel 认为人是最能反映一个时代的真实情况,所以她选择 painted portrait。

  33.Why does the professor discuss the variety of people in Neel's portraits?

  A.To explain why it took Neel a long time to find her characteristic style

  B.To explain why Neel experimented with genres other than portraiture

  C.To identify elements of Realism and Expressionism in Neel's paintings

  D.To emphasize a distinctive feature of Neel's body of work

  答案:D

  解析:(原文中)Professor: ...If your looked at them, it is like this gallery of the whole century, an enormous range of subjects: families, women, children, artists, people in poverty--these paintings really span class, age and gender. It is like she transformed the genre, it is not just formal depictions of presidents and ancestors any more.

  从内容联系上可知,教授提及在 Neel 中的许多人物是为了说明她的作画特点。

  34.Why does the professor say this: (复听题)

  A.To influence the students' opinions about Alice Neel's work

  B.To suggest that Alice Neel created her best paintings late in her career

  C.To reinforce the fact that Neel's work was not appreciated

  D.To show that Alice Neel's situation was similar to his own

  答案:C

  解析:(原文中)Professor: ...And I guess you might say, she experienced difficulties as an artist. She was in her 70s, before she had her first major solo exhibition.

  教授在说到这句话是为了进一步说明 Neel 在成名的路上并不顺利,作品之前并没有受到很大的认可和欣赏,直到70多岁,作品才首次被单独展出。
