Question

【题目】So far all cloned animals have suffered from some different serious disorders, ________ dying soon after birth.

A. many of them B. many of whom

C. many of which D. many of that

Answer 1

【答案】A

【解析】考查现在分词的独立主格结构。句意：但目前为止，所有克隆动物都患有不同的严重疾病，它们中很多出生后不久就死去。独立主格结构不是句子，是短语，但是它的作用相当于句子。many of them dying soon after birth=" and" many of them are dying soon after birth.本句题干中缺少连词，说明后面不是句子，排除B/C. that指代单数名词，而这里的them指代的all cloned animals，应该使用复数形式。故选A。
