LSAT TEST1 SECTION1 NO。17，答案是A，我选的是B。关键是从题目中，没办法看出A中所谓的rob the human race
17. The peculiar evil of silencing the expression of an opinion is that it robs the human race. It takes from posterity, as well as the existing generation, and from those who dissent from the opinion even more than from those who hold it. If the opinion is right, they are deprived of the opportunity of exchanging error for truth; if it is wrong, they lose what is almost as great a benefit: the clearer perception and livelier impression of truth, produced by its collision with error.
Which one of the following best expresses the conclusion presented in the argument?
(A) Silencing the expression of an opinion is robbing the human race.
(B) Silencing the expression of an opinion harms those who dissent more than those who agree.
(C) Anyone who agrees with an opinion would not want to silence its expression.
(D) Gaining a clearer perception and livelier impression of truth is a great benefit.
(E) The greatest benefit is the opportunity of exchanging truth for error.
TEST1 SECTION4 NO。18，答案是E，我选的是D。题目就不太懂。
If the artificial is not better than the natural, to what end are all the arts of life? To dig, to plow, to build, to wear clothes—all are direct violations of the injunction to follow nature.
18. If the author’s argument were challenged on the grounds that the construction of buildings has adverse effects on the natural environment, which of the following replies might the author use to respond to the challenge logically?
(A) There are human activities, such as making music, that are environmentally harmless.
(B) Harming the environment is not an end, of purpose, of the arts of life.
(C) The construction could involve the use of natural, not artificial, materials.
(D) Constructing buildings is not an “art of life.”
(E) Even if the natural environment is disturbed by the construction of buildings, it is improved for human use.
NO。22，答案是A，我选的是C。也是题目不懂。
22. It is illogical to infer a second and different effect from a cause which is known only by one particular effect. This is incorrect because the inferred effect must necessarily be produced by some different characteristic of the cause than is the observed effect, which already serves entirely to describe the cause.
Which one of the following arguments makes the same logical error as the one described by the author in the passage?
(A) An anonymous donor gave a thousand dollars to our historical society. I would guess that that individual also volunteers at the children’s hospital.
(B) The radioactive material caused a genetic mutation, which, in turn, caused the birth defect. Therefore, the radioactive material caused the birth defect.
(C) The tiny, unseen atom is the source of immense power. It must be its highly complex structure that produces this power.
(D) The city orchestra received more funds from the local government this year than ever before. Clearly this administration is more civic-minded than previous ones.
(E) If I heat water, which is a liquid, it evaporates. If I heat hundreds of other liquids like water, they evaporate. Therefore, if I heat any liquid like water, it will evaporate
新年好!
17关键在于你要看出题目的中心句子,就是第一句啊,你好好体会一下题干的全部意思
18题目说的意思是人类的活动the artificial is better than the natural,所以E
22题干描述了一种逻辑错误,问的是哪个推断犯了这种错误,你仔细阅读一下题目
我做LSAT,觉得你的速度一定要快起来,掐一下时间做,45分钟内25题,因为时间太长,做的再好也没用,我觉得一定要培养在时间非常紧的情况下阅读做题,我上次没考好就是阅读速度问题,如果你的阅读不是非常好,我建议你先练阅读,再做LSAT,还有LSAT里面的一些题目类型GMAT不会考的,羊年共勉!!!作者: bob 时间: 2003-2-4 19:48
非常谢谢tbs，18题的If the artificial is not better than the natural, to what end are all the arts of life? 是什么意思？恕我愚笨。
我的最大问题是速度慢，你说的非常有道理，我现在的水平是GRE四篇55分钟错0-2题。速度慢，做的好也没用，真是着急啊。
另外，LSAT中的什么题目是GMAT不考的？？？盼告之。作者: tbs 时间: 2003-2-5 20:41
1.If the artificial is not better than the natural, to what end are all the arts of life? 这是一句反问句,意思就是说the artificial is better than the natural
2.LSAT逻辑中的逻辑类比题(比如问下面那个推理和题干是同样的推理模式),还有一些纯逻辑推理的题目GMAT是没有的,由于机考的题目都很长,这一点和LSAT的很近,所以逻辑的关键还是阅读!
3.不要太着急,因为欲速则不达,要培养很紧张的心理状态下做题的能力,这也是我的问题.加油!
