129. In an effort to reduce their inventories, Italian vintners have cut prices; their wines have been priced to sell, and they are.

(A) have been priced to sell, and they are

be priced to sell，强调的是sell的动作，而不是前面的priced，注意and后面的have/do以及are的所指代的对象；

(B) are priced to sell, and they have

have与are见上说明，同时还有时态的问题；

(C) are priced to sell, and they do

do指代sell，符合逻辑结构，见上说明；

(D) are being priced to sell, and have（C）

have无所指代，也无所省略；时态；

(E) had been priced to sell, and they have

见A中的说明；同时时态问题；

In choice C, the best answer, do is correctly used in place of the full verb do sell; in this verb, do is a conjugated form and sell is in the infinitive form, corresponding to its previous use in the sentence (in the phrase priced to sell). In choice A, the omitted word is selling; in B, D, and E, it is sold. Neither of these forms corresponds properly to to sell earlier in the sentence. Also, in E, the past perfect had been priced signifies that the wines had been priced to sell before the prices were cut.

What does this question mean? 不知道楼主要问的是什么

136. Although schistosomiasis is not often fatal, it is so debilitating that it has become an economic drain on many developing countries.

(A) it is so debilitating that it has become an economic

(B) it is of such debilitation, it has become an economical

(C) so debilitating is it as to become an economic

第一，偶还没见过so as to 可以倒装的，这点偶不敢肯定；第二：很明显时态与原文不同：原文的Has become与答案中 to become一般时态的区别；在没有其他时间标志的情况下，尽量保持原句的时态，除非有明显的错误；

(D) such is its debilitation, it becomes an economical（A）

(E) there is so much debilitation that it has become an economical

Choice A is best: is links the noun schistosomiasis with its modifier, debilitating, and so debilitating that idiomatically introduces a clause that provides a further explanation of debilitating. Choices B, D, and E produce awkward, wordy, imprecise, or unidiomatic phrases by substituting the noun debilitation for the modifier debilitating. Choices B and D fail to introduce the explanatory clause with that, and C uses an awkward and wordy construction in place of a that... clause. Finally, B, D, and E wrongly use economical instead of economic to mean “pertaining to the economy.”

Why c is awkward and wordy.

139. The extraordinary diary of William Lyon Mackenzie King, prime minister of Canada for over twenty years, revealed that this most bland and circumspect of men was a mystic guided in both public and private life by omens, messages received at séances, and signs from heaven.

(A) that this most bland and circumspect of men was a mystic guided in both public and

(B) that this most bland and circumspect of men was a mystic and also guided both in public as well as

(C) this most bland and circumspect of men was a mystic and that he was guided in both public and

(D) this most bland and circumspect of men was a mystic and that he was guided in both public as well as（A）

(E) this most bland and circumspect of men to have been a mystic and that he guided himself both in public as well as
