P645——Section 3
批评家的风格
6. ANSWERS AND EXPLANATIONS
Explanation for Correct Answer B :
Choice (B) is correct. The passage says that Wilson "speaks directly through his letters" (line 5) and that those letters "undisguisedly reflect his changing moods." (lines 6-7). It also describes his letters as "informal" (line 5). Together these descriptions strongly suggest that Wilson's letters were spontaneous. This suggestion is reinforced by things the passage says Wilson did not do in his letters: he did not rely on "studied mannerisms" (lines 2-3), and avoided "artifice" (line 3) and "circumlocutions" (line 4). In other words, he did not put carefully crafted language into his letters to achieve specific effects.
Explanation for Incorrect Answer A :
Choice (A) is incorrect. "To be cynical" is to be contemptuous and distrustful of motives. Nothing in the passage suggests that Wilson's letters had this quality. It is possible that some of the "changing moods" that the letters "undisguisedly reflect" are cynical moods. But there is no information in the passage to suggest that he actually had cynical moods. So the passage gives no reason to call any of his letters cynical, much less to describe them generally as cynical.
Explanation for Incorrect Answer C :
Choice (C) is incorrect. The passage says that Wilson's letters reflected his moods and that those moods were changing. So what the passage says leaves it open that some of Wilson's moods—and so some of his letters—might be critical. But the passage does not include any information that suggests that the letters as a whole were critical.
Explanation for Incorrect Answer D :
Choice (D) is incorrect. Letters that are “preachy” are going to be full of moral urgings and appeals. But the passage says that Wilson was not a self-conscious letter writer, that is, that he did not plan out what she was going to say or write to achieve some particular end. The passage does say that on occasion Wilson could “become eloquent, even passionate” (line 9). But the passage goes on to say that “that is not his prevailing tone” (lines 9-10).
Explanation for Incorrect Answer E :
Choice (E) is incorrect. The passage says that as a letter writer, Wilson was not self-conscious and that he did not aim for any particular style or manner. This strongly suggests that Wilson did not try to make his letters especially "witty," or amusing and clever. It is possible that he was a naturally witty man and that his letters simply reflect that wit. But nothing in the passage indicates that this was so.

7. ANSWERS AND EXPLANATIONS
Explanation for Correct Answer E :
Choice (E) is correct. The passage uses the phrase "the young, middle-aged, and old Wilson" to say that age made no difference with respect to Wilson's letters being generally direct, informal, and straightforwardly expressive of his moods. So the phrase emphasizes that Wilson's letter-writing style was consistent throughout his life.
Explanation for Incorrect Answer A :
Choice (A) is incorrect. The reference to "the young, middle-aged, and old Wilson" is used to indicate that throughout his life, Wilson wrote letters that were generally direct, informal, and straightforwardly expressive of his moods. So the point of the reference is to stress a certain constancy in his letter-writing style, not to suggest that his writing was multifaceted, or many-sided. Since he was a critic, his writing clearly extends well beyond letter writing, so his literary persona is not defined solely by the letters he wrote. But the passage does not discuss any other writing he did.
Explanation for Incorrect Answer B :
Choice (B) is incorrect. The way the passage talks about Wilson's stylistic approach to letter writing suggests that his approach was consistent throughout his life. But what it says about his style indicates nothing about the level of maturity that Wilson displayed at any age. The passage does not address the fact that Wilson might have been immature when young and still have written letters that were direct, informal, and reflected his changing moods.
Explanation for Incorrect Answer C :
Choice (C) is incorrect. The passage talks about Wilson's letters as though his approach to writing them did not change much in the course of his life. Characterizing the writer of those letters as "the young, middle-aged, and old Wilson" serves to reinforce this life-long consistency. Nothing in the passage suggests that aging had any effect on Wilson's temperament.
Explanation for Incorrect Answer D :
Choice (D) is incorrect. The reference to "the young, middle-aged, and old Wilson" suggests that Wilson wrote letters over a long period of time. The passage introduces Wilson as a critic, which indicates that he had a literary career. But the passage gives no information about his career as a literary figure.

8. ANSWERS AND EXPLANATIONS
Explanation for Correct Answer C :
Choice (C) is correct. The passage suggests that there is pressure on authors who write about the leaders of the Black community to portray those leaders as perfect (i.e., as being above reproach). The passage explains that this pressure has its origins in the belief, held by some, that exploring the full humanity of the leaders of the Black community would harm that community.
Explanation for Incorrect Answer A :
Choice (A) is incorrect. The passage implies that authors who write about the leaders of the Black community will feel pushed towards portraying those leaders as being perfect. Since portraying someone as overly sentimental is a case of portraying that person as falling short of perfection, the passage does not support the idea that Black leaders are portrayed in this way.
Explanation for Incorrect Answer B :
Choice (B) is incorrect. The passage is concerned that portrayals of Black leaders do not capture the breadth and complexity of Black identity. So, if anything, the passage implies that Black leaders are generally portrayed as less complex than they actually are.
Explanation for Incorrect Answer D :
Choice (D) is incorrect. Black leaders may generally be portrayed as perfect, but this does not suggest that they are never portrayed as feeling regret over anything. A person may well feel regret over the way things are or about things that happen that are beyond their control.
Explanation for Incorrect Answer E :
Choice (E) is incorrect. The passage implies that portrayals of Black leaders tend to be false in certain respects. But this does not mean that those leaders are portrayed as being beyond understanding. Rather, it is implied that readers can understand what they are being told about those leaders well enough for the portrayals to be useful.

9. ANSWERS AND EXPLANATIONS
Explanation for Correct Answer B :
Choice (B) is correct. The reference to "authors" (line 2) indicates that the passage is about written works; specifically, the passage deals with written works about the leaders of the Black community. In other words, those works are most likely historical biographies. The passage questions whether those works are full investigations of Black life, and then refers to these investigations as "paintings of that life" (lines 5-6). The phrase "paintings of that life" is thus used metaphorically for biographical writings.
Explanation for Incorrect Answer A :
Choice (A) is incorrect. There is no indication in the passage that "paintings" might refer to sculptures. No sculptors are referred to, or even hinted at, as the originators of these works, whom the passage explicitly calls "authors" (line 2). Those authors are said to face problems with producing a "full investigation of Black life" (line 5). This further reinforces the idea that "paintings" refers to work that is well suited to extended discussion and development, that is, written work.
Explanation for Incorrect Answer C :
Choice (C) is incorrect. There is no reason to think that the reference to "our leaders" (line 2) is to anyone but real-life leaders of the Black community. So the works that have those leaders for subjects are likely to be biographies (i.e., nonfiction), not novels. There is also no indication that these works are whimsical. They may fall short of being full investigations of Black life, but this is because there is pressure for them to be selective, not pressure to take a light, humourous tone. In fact, the passage implies that these works are "drab and predictable" (lines 6-7).
Explanation for Incorrect Answer D :
Choice (D) is incorrect. There is no support in the passage for taking "paintings" (lines 5-6) to be a reference to political cartoons. Political cartoons are well suited to directing a spotlight on a specific action or event, and to the extent that they comment on character, good cartoons are generally regarded as uncannily revealing. The works that the passage discusses are essentially the opposite: broad in scope, yet the overall picture they provide is, according to the passage, likely to be unrevealing. In fact, the passage calls these paintings "likely to be untrue" (lines 7-8).
Explanation for Incorrect Answer E :
Choice (E) is incorrect. The concept of a theorem is appropriate only to rigorous logical/mathematical work. The passage is not about such work. And while it is quite commonplace to talk about written prose work as painting a picture of its subject matter, theorems are not talked about in this way. Moreover, the "paintings" are explicitly characterized as "drab" (line 6), not as colorful.

P646——Section 3
时光旅行
10. ANSWERS AND EXPLANATIONS
Explanation for Correct Answer B :
Choice (B) is correct. According to the passage, astronomers who see Andromeda though their telescopes see it as it was two million years ago because that is how long it takes light from the galaxy Andromeda to reach Earth. To give the reader a vivid idea of how much things can change in two million years, the author points out that the long-extinct humanlike primate Australopithecus was alive on Earth two million years ago.
Explanation for Incorrect Answer A :
Choice (A) is incorrect. The fact that Australopithecus was alive on Earth two million years ago indicates that there has been an evolutionary change in at least the biological world during that period. But that passage is not concerned with such progression in itself. The point that the author wants to make is how different the world of the distant past is from the world we know today.
Explanation for Incorrect Answer C :
Choice (C) is incorrect. That Australopithecus was alive two million years ago is certainly not something astronomers discovered. The author says nothing to suggest that what astronomers do when they see Andromeda through their telescopes is isolate a particular moment in early time. Nor does the author commend astronomers on their work. The point the author is making with the reference to Australopithecus is simply how ancient the images are that astronomers are now receiving from Andromeda.
Explanation for Incorrect Answer D :
Choice (D) is incorrect. The author mentions both Andromeda and Australopithecus as a way of vividly making the point that the distant past is very different from the present. Moreover, two million years is how long it takes light to reach from the Andromeda galaxy, not how long ago the Andromeda galaxy was discovered.
Explanation for Incorrect Answer E :
Choice (E) is incorrect. The author mentions Australopithecus to emphasize the length of the time it takes for light to travel between Earth and Andromeda. Nothing in this passage or the rest of the paragraph discusses the age of the universe or the length of time humans have lived.
11
11. ANSWERS AND EXPLANATIONS
Explanation for Correct Answer A :
Choice (A) is correct. The author begins by observing that when astronomers see Andromeda through their telescopes, they “see it as it was two million years ago” (lines 2-3). He then points out that two million years ago on Earth was about the time of Australopithecus and remarks that “it is too bad we can’t turn things around and observe Earth from some cozy planet in Andromeda” (lines 6-7). Since scientists would very much like to know more about Australopithecus and other early humanlike primates, this remark is a way of saying that scientists would like to have some way of observing events that occurred on Earth before these primates became extinct.
Explanation for Incorrect Answer B :
Choice (B) is incorrect. The passage is concerned with the idea of time travel, not space travel. And since it takes light two million years to travel between Andromeda and Earth, the idea that people could actually go to a planet in Andromeda is not one that the author, as a scientist, is likely to take seriously.
Explanation for Incorrect Answer C :
Choice (C) is incorrect. The point of wishing we could observe Earth from a planet in Andromeda is that we would see Earth as it was two million years ago. The passage does not suggest that we would be on that planet in Andromeda to study Andromeda, or that there would be interesting comparisons to be made with Earth if we did.
Explanation for Incorrect Answer D :
Choice (D) is incorrect. Andromeda is so far away that it takes light two million years to travel between it and Earth. Thus, the idea that people could actually get to a planet in Andromeda is not one that, as a scientist, the author is likely to take seriously.
Explanation for Incorrect Answer E :
Choice (E) is incorrect. It can be inferred from the passage that both Andromeda and Earth are more that two million years old. But the passage says nothing that bears on their relative ages.

12. ANSWERS AND EXPLANATIONS
Explanation for Correct Answer E :
Choice (E) is correct. The author describes being fascinated by the idea of time travel. To make this fascination understandable he gives two examples of what time travel could make possible: modern medical knowledge could be taken back to fourteenth century Europe "to stop the spread of plague," and one could go forward "to the twenty-third century, where people take there annual holidays in space stations."
Explanation for Incorrect Answer A :
Choice (A) is incorrect. The author suggests that some novels about time travel have fascinated him, but he says nothing to indicate what the specific themes of those novels might have been.
Explanation for Incorrect Answer B :
Choice (B) is incorrect. The reference to space stations does suggest a view about what the future might bring. But no alternative view is suggested. The reference to the plague has to do with the past, not with the future.
Explanation for Incorrect Answer C :
Choice (C) is incorrect. In lines 16-35, the author presents the scientific consequences of time travel quite seriously. There is no indication that he finds those consequences ridiculous or scoffs at them.
Explanation for Incorrect Answer D :
Choice (D) is incorrect. The idea of being able to stop the spread of the plague in fourteenth-century Europe is presented as something that anyone might find interesting. There is no indication that the author believes scientists would find the idea more interesting than anyone else would. In fact, the author strongly suggests that most physicists would not like the idea at all because it would involve a "causality violation."
13
13. ANSWERS AND EXPLANATIONS
Explanation for Correct Answer B :
Choice (B) is correct. The first two paragraphs present time travel as an attractive idea. In the third paragraph, the author switches gears and discusses some of the theoretical difficulties time travel would present. Time travel, the author says, would run counter to the laws of physics. This is the kind of claim that can be made with a lot more authority by a scientist than by someone who has no scientific training. So by introducing himself as a scientist before making these claims, the author presents himself as someone with the authority to speak on these matters.
Explanation for Incorrect Answer A :
Choice (A) is incorrect. Even though the author traces his interest in time travel back to his childhood, when he became old enough to read science fiction, this fact in itself would not indicate that scientific training. Also personal interest in a topic does not necessarily make one an authority.
Explanation for Incorrect Answer C :
Choice (C) is incorrect. Whatever general appeal certain forms of literature—including science fiction—might have cannot be explained by the fact that the author of this passage is a scientist.
Explanation for Incorrect Answer D :
Choice (D) is incorrect. The author seems to enjoy at least some science fiction. So it is unlikely that he would be interested in provoking those who defend it.
Explanation for Incorrect Answer E :
Choice (E) is incorrect. Being a scientist might help the author explain the term "causality violation," but describing himself as a scientist does not help illustrate the term.
14
14. ANSWERS AND EXPLANATIONS
Explanation for Correct Answer C :
Choice (C) is correct. In lines 16-35 the author discusses some theoretical problems associated with the idea of time travel. The mechanics of space travel do not raise any of these problems and are not mentioned anywhere in the passage.
Explanation for Incorrect Answer A :
Choice (A) is incorrect. The issue of anticipatory knowledge of events is addressed in lines 18-20.
Explanation for Incorrect Answer B :
Choice (B) is incorrect. The issue of belief in a deterministic universe is addressed in lines 30-35.
Explanation for Incorrect Answer D :
Choice (D) is incorrect. The issue of cause-and-effect relationships is addressed in lines 21-22.
Explanation for Incorrect Answer E :
Choice (E) is incorrect. The issue of differential equations based on known forces is addressed in lines 28-32.
