Q14

Section 301 of the 1998 Omnibus Trade and Competitiveness Act enables the United States Trade Representative to single out a country as an unfair trader, begin trade negotiations with that country, and, if the negotiations do not conclude by the United States government’s being satisfied, to impose sanctions.

A. by the United States government’s being satisfied, to impose

B. by the United States government’s satisfaction, impose

C. with the United States government’s being satisfied, imposing

D. to the United States government’s satisfaction, impose

E. to the United States government’s satisfaction, imposing

答案 D

“government’s being satisfied”错=>排除AC，但是BDE该怎么区分？请牛牛指点

为什么选D呢？

通过  enable ..to single out ..., begin... ,and if... , impose 排出 ACE 然后B D

conclude to??? 只知道有 to conclude

D是这样的：

to single out , (to) begin ...,and (to) impose...

并列的三个不定式，第二个to省略，and后面的to也省略。

B用by应该用被动语态吧

我也想问问B和D的区别

豁然开朗，谢谢iamsan1984
