大全559有不懂请教

559     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

解释说：

A) be prohibit from + n不好
B) that was banned修饰对象不清。
C)best. directive用doing简洁比A更优。

D) prohibit that错。
E) 要用虚拟

可以：prohibit sth, prohibit sb. from doing sth.

我不明白为什么E错，为什么要用虚拟？that前的recind都不要用虚拟啊！而C的other countries of 后面修饰得怪怪的

不懂

E中that 后面确实要用虚拟,directive that .....(should)这个结构

the sale (to other countries) of any chemical
            banned on medical grounds, 修饰紧凑，句意清楚；如果将to the countries 置后，句子较分散。

个人认为directive表指示、命令，用虚拟比一般时（choice E) 好，但这里用prohibiting 直接修饰directive 更简洁。曾经见过类似的句子，但不记得是在og还是在大全里了。Hope this helps!
