19. The herbicide Oryzalin was still being produced in 1979, three years after the wives of workers producing the chemical in Rensselaer, New York, were found to have borne children with heart defects or miscarriages, and none of their pregnancies was normal.
(A) to have borne children with heart defects or miscarriages, and none of their pregnancies was
(B) to have had children born with heart defects or miscarriages, and none of the pregnancies was
(C) either to have had children with heart defects or miscarriages, without any of their pregnancies being
(D) either to have had miscarriages or to have borne children with heart defects; none of the pregnancies was
(E) either to have had miscarriages or children born with heart defects, without any of their pregnancies being
答案选D。我觉得这几个答案都不太好，但D是尤其不能选的一个。
句子的结构是Oryzalin was ...produced, three years after the wives...were found...划线部分是found的宾语，整个合在一起是after引导的时间状语从句，而after引导的这个结构是用来修饰Oryzalin was ...produced这个主句的。D里面用了一个分号，就使得分号后面的结构none of the pregnancies was normal成为了一个与主句Oryzalin was ...produced并列的结构而不再是修饰成分的一部分了，严重改变了原句的意思。
几个答案虽然都不好，但比较而言B似乎在结构上没有什么错误。
请NN指教。
OG的解释：
Choices A and B are incorrect because with governs both heart defects and miscarriages; in other word, choice A says that the children and not the women suffered the miscarriages. For the sentence to make sense, miscarriages must be the object of a verb that has wives as its subject. Also, their in choices A, C, and E is ambiguous because it is far from its referent, wives. Choices C and E lack parallel construction: a verb form like the one after either should appear after or. Choice D is the best answer for this difficult question.
