638.Several years ago the diet industry introduced a variety of appetite suppressants, but some of these drugs caused stomach disorders severe enough to have them banned by the Food and Drug Administration.
(A) stomach disorders severe enough to have them
(B) stomach disorders that were severe enough so they were
(C) stomach disorders of such severity so as to be
(D) such severe stomach disorders that they were(D)
(E) such severe stomach disorders as to be
这里为什么不能选E呢,such as to的用法应该是没错呀。。。而且我觉得D里面they有指代不清的嫌疑,请各位NN为在下解惑,感谢感谢~~~ |
