16. One of Ronald Reagan’s first acts as President was to rescind President Carter’s directive that any chemical banned on medical grounds in the United States be prohibited from sale to other countries.
(A) that any chemical banned on medical grounds in the United States be prohibited from sale to other countries
(B) that any chemical be prohibited from sale to other countries that was banned on medical grounds in the United States
(C) prohibiting the sale to other countries of any chemical banned on medical grounds in the United States
(D) prohibiting that any chemical banned on medical grounds in the United States is sold to other countries（C）
(E) that any chemical banned in the United States on medical grounds is prohibited from being sold to other countries
我选E 为什么答案选C?
觉得directive后面应该跟that引导的同位语从句来，为什么直接就是prohibit了呢？E 错在哪里？
我的分析是：
A 不该用虚拟语气
B 应该是prohibit from doing ，prohibit from sth 错
C directive 后面应接that的同位语从句
D prohibit后面不跟that从句 |
