gwd语法汇总中的疑惑5

54. The electronics company has unveiled what it claims to be the world’s smallest network digital camcorder, the length of which is that of a handheld computer, and it weighs less than 11 ounces.

(A) to be the world’s smallest network digital camcorder, the length of which is that of a handheld computer, and it weighs

(B) to be the smallest network digital camcorder in the world, which is as long as a handheld computer, weighing

(C) is the smallest network digital camcorder in the world, which is as long as a handheld computer, and it weighs

(D) is the world’s smallest network digital camcorder, which is as long as a handheld computer and weighs                                                       D

(E) is the world’s smallest network digital camcorder, the length of which is that of a handheld computer, weighing

我认为B比D更合理。首先，What it claims is 是it claims what is 的转换形式，是否要用逗号隔开it claims, 即what, it claims, is? Claim to be是正确的。其次，从句和分词可以并列修饰同一名词（这种情况我见过），在这里我认为不会产生歧义。

60. Whereas lines of competition are clearly defined in the more established industries, in the internet industry they are blurred and indistinct , as companies that compete one day may be partners the next

A. Whereas lines of competition are clearly defined in the more established industries, in the internet industry they are blurred and indistinct, as companies that compete

B. although the lines of competition are clearly defined in industries that are more established, they are blurred and indistinct in the internet industry , as competing companies

C. the lines of competition are clearly defined in the more established industries, unlike the internet where they are blurred and indistinct , as companies that compete

D. unlike more established industries, where the lines of competition are clearly defined, they are blurred and indistinct in the internet industry, as companies that compete                B

E. unlike more established industries, with clearly defined lines of competition, those of the internet industry are blurred and indistinct, as competing companies

答案：B。我选A。

B中的错误：首先，that are 应该省略（ETS的偏爱）其次，One day 和the next (day)共同作句子的状语，意思很荒谬。

63. The new sports car is heavier than usual for a performance automobile, but it is exceptional because of its high-powered engine.

A) usual

B) it is usual

C) one usually is

D) is usual                                                           D

E) has been usual

答案：D

B的错误在于，主语相同，应该省略？有点困惑！

74. The studio’s retrospective art exhibit refers back to a simpler time in Amer

ican history.

(A) The studio’s retrospective art exhibit refers back to

(B) The studio’s retrospective art exhibit harkens back to

(C) The studio’s retrospective art exhibit refers to

(D) The studio’s retrospective art exhibit refers from

(E) The studio’s retrospective art exhibit looks back to  

Answer: C

我认为答案改变了句意。E的错误在哪？

建议shaya把题分开问.

54. 首先，What it claims is 是it claims what is 的转换形式. 这我还是第一次学到. 谢谢. 此题我也错选就是因为没看出这个结构.我觉得不需要逗号. B的问题还是在which. 相对D好的多.

60 A 的they指代不清.

63 和74帮你顶一下.

Choice (A) is incorrect. Retrospective means looking back on the past. Hence, in the phrase refers back, the word back is redundant.

Choice (B) is incorrect because harkens back is also redundant.

Choice (C) is correct. Dropping the word back eliminates the redundancy.

Choice (D) is incorrect because the preposition from is non-idiomatic.

Choice (E) is incorrect because looks back is also redundant.

对74题在D和C之间忧郁了一下, 还是选了D, 觉得从中文翻译D更通些. 看来这还是再考idiom.

谢谢Jnlvo班主, 另外请教一下63题.

63.这题原引800score,原题说明：

(D) is the correct answer.  It employs the parallel construction, 'the sports car is.... than (is) usual for a ...'.  (A) is ruled out because it does not create a parallel comparison. In (B), the 'it' is redundant; so is the 'one' in (C). (E) is incorrect because of the verb tense, which should stay in the present. (D) is the best answer because it uses parallel construction.

在GWD中有类似的题，当时争论的很厉害，主要是than usual和than is usual区别。可我一下查不到了，你可留意一下。印象中princeton上也有类似一题给了than is usual的答案，但这还不足以作为最终的判定。

谢谢Jnlvo班主解释, 对D的是否可以还原成下面的形式.

The new sports car is heavier than (sports car) is usual for a performance automobile, but it is exceptional because of its high-powered engine.

对前半句的for a performance automobile应该如何理解.

更正一下，可能的理解是than (what) is usual for  a performance automobile. 这里可能不用than usual的原因就是会造成歧义，是what (car) usual for a performance automobile还是usual new sports car for a performance automobile

类似的例子：

A grasshopper is larger than normal for a member of the insect class; its abdomen can be up to two inches in length, as opposed to the one-inch-long abdomen of the average insect.

a.normal

b. is normal

c. was normal

d. they normally are                                               B

e they are normally

而og253中选the weather, which was colder and wetter than usual in some regionsutom实际想表达的就是usual weather.这里不会有歧义产生，用习惯表达than usual更简洁。

看到Jnvlo板主的第一个例子, 这是我的想法

The Parthenon is larger than usual: 歧义应该是出在larger和usual进行了比较. 虽然两个形容词不可比, 但是会给人疑惑.加了is就很清楚是两个Parthenon进行比较了.

回到原题, 如果不用is, 就会感觉是heavy 和usual进行比较. 所以D会更清晰.
