Section 301 of the 1988 Omnibus（公共汽车） Trade and Competitiveness Act enables the United States Trade Representative to single out（挑选） 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.

1. by the United States government’s being satisfied, to impose
2. by the United States government’s satisfaction, impose
3. with the United States government’s being satisfied, imposing
4. to the United States government’s satisfaction, impose
5. to the United States government’s satisfaction, imposing

 

Answer: D

impose 要和begin平行，这个我看的出来

但是查词典只找到conclude +by, with,that或者 conclude to do sth.决定干某事’

这里的conclude to +n.，那TO就应该是介词了，有这种用法吗？中文意思是什么？请知道的NN指教
