NN我想再问一个问题
While studying thegenetic makeup of corn, a new class of mutant genes was discovered byBarbara McClintock, a discovery which led to greater understanding of celldifferentiation. A. a new class of mutant genes was discovered by Barbara McClintock, adiscovery which led B. a new class of mutant genes in corn were discovered by BarbaraMcClintock, leading C. Barbara McClintock discovered a new class of mutant genes, and it led D. Barbara McClintockdiscovered a new class of mutant genes, a discovery that led (D) E. Barbara McClintock, who discovered a new class of mutant genes, leading 这里D是同位语,prep08的笔记里说是同位语修饰前面整个句子,可我看之前的笔记又说同位语只能修饰noun或名词短语,这里怎么解释?
那如果这里的a discovery 是做a new class of mutant genes的同位语的话,那么C中的it不也是指代也是a new class of mutant genes吗?那这CD不就没有区别了吗? |
