GMAT考虑到开始讨论的人可能少点，所以先归在综合区，以后如果有必要，就单独出来。

想问一下LSAT板块的功能是什么,顾名思义应该是讨论LAST题目的地方，可是为何没有人在此讨论呢？枉费Lawyer苦心了。

我来问一题，请大家帮忙解答解答。

1-4-14.      All those who keep a journal will be heard by the next generation. Some of these journal writers are true artists, others humorous observers of the commonplace, and still others insufferable egotists who feel compelled to record their every thought.

If the statements above are true, which one of the following must be true?

(A) Not all of those who are humorous observers of the commonplace will be heard by the next generation.

(B) Everyone who will be heard by the next generation keeps a journal.

(C) The next generation will hear both insufferable egotists and true artists.

(D) Some of those who keep journals are not true artists, humorous observers of the commonplace, or insufferable egotists.（C）

(E) The next generation will bear some of those who are true artists but not all of them.

请问这里的充分必要怎么推的？

Questions 17-18

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.

1-4-17.   Which one of the following is an assumption made by the author of the passage?

(A) The arts of life have no useful end.

(B) The artificial is not better than the natural.

(C) Digging, plowing, building, and wearing clothes are better than nature.

(D) The injunction to follow nature should not be violated.（C）

(E) The arts of life are indirect means of following nature.

1-4-18.   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, or 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）

(E) Even if the natural environment is disturbed by the construction of buildings, it is improved for human use.

这两题我都做错了，请看我的思路哪里不对：

17. 第一句反问句,证明作者观点:artificial 比 natural 好; 后一句举例说明artificial的东东违法, 所以我选了D. 正确答案是C, 而题目问的是assumption, C看上去有infer之嫌. 请NN解释!

18. 正确选项E, natural environment已经disturbed了, 怎么能再improved呢?

再有, 此题粗体部分不理解, arts of life指什么? 非常感谢!

17题你后半句理解错了.题目里不是说 artificial 不好，而是反问说如果artificial不好,那么To dig, to plow, to build, to wear clothes 这些就违反了自然,就是不好的了.

实际上提干就是说,To dig, to plow, to build, to wear clothes是好的.就像说,如果网络不好,那么EMAIL,网上新闻浏览也就是不好了.反问句哦~~仔细想想.所以E是正确的假设.

18题你理解错了.the author 用E来refute 说construction of buildings has adverse effects on the natural environment,他用E来说明construction of buildings 是对人有利的,improve的是人类的生活.不知道可以不可以理解为他因削弱.

以上仅供参考

17. MM没有看清我的问题, 我也认为作者的观点是说artificial好, 但是正确选项C好像是infer题的答案, 而不是assumption题的答案. MM再看看.

18. it指代什么?

celina1983

17 我没理解错 JJ的意思啊,因为是假设题,所以应该找必要条件,因为C是author 自己举的论据,试想,如果这个论据不成立,他的结论当然就不成立了!

所以是假设.

18我觉得it是指  natural environment .JJ可能要问,不是说被破坏了么,可是 E说的是从对于人类来说是改善了.是从人类的利益讲的.

不知道我说清楚了没有
