128. (31405-!-item-!-188;#058&006278)

A Food and Drug Administration rule implemented in December 2000 mandates that any new drug that they intend to be used both by adults and children must undergo pediatric study and that its manufacturers list children's doses on the label.

(A) drug that they intend to be used both by adults and children must

(B) drug whose intended use is for adults and children as well

(C) drug intended for use by both adults and children

(D) drug, if they intend that it be used by adults and also children, must

(E) drug, if intended for use both by adults and children, must

答案选C，但我觉得undergo应该换成undergoes，因为drug是单数，而且最后半句用了its manufacturers

求高人指点

是不是因为mandate that A （should）do 呢

mandate 的用法是这样的：因为他本身就有强制执行的意思，那么mandate that 后面凡是加 should， must，都是错误的，导致意义重复，其次，mandate that 后面的动词形式是用原型的，即使 drug 是单数，undergo 必须是原形，这个和 require 用法后面的动词要用原形是一个道理。希望我讲明白了~~呵呵
