请问解题思路？

157、要想在逻辑上合适，则and whose requests have increase 必须是被动才行。
158、if引导的是条件句。一般是用现在时态表主句的。好象没有用can的，因为有些意思 上的重复。

171. impact是及物动词，后面不加to
173. 从句意上看，应该用smooth修饰wings,不是smoothly修饰动词shape
193. most 前要加the 表示最高级， 用since 自从

157. whose request 专家的需求；request for whom 对专家的需求；E符合句意。

tongxun

同意两位的看法。

jeff0613

158. 如果选C, 主句应用television will be...

tongxun

jeff0613：不一定啊。

159. B中it指代manufacturer不符合句意；E的表达最简洁，可理解为having test-driven cars disconnected with their odometers.

来加个几笔吧 157. benefit from 1.the increasing demand and from 2.the higher profit 较佳 158. 我觉得主句用现在式或未来式都无妨, as when中as应作副词解, 有一点我不太确定, 即在表达非常可能发生的事件时, 用when比用if好 159. damages for cars that were test-driven with their odometers disconnected. (E)having cars that were test-driven with their disconnected odometers. for表达damage的原因, 表达一个动作的事件, 而非车子本身, 所以having比car好 171. 表可能性减少, 用diminish比 impede好 193. become the tenth most intense hurricane… and (D)the most intense after 1969,which had Camille. (E)since 1969 and Camille,the most intense. 这里的the most intense (one) 被省略了…, 请教比较级与最高级修饰的单数名词都可以省略吗?
