So, here's what researchers think is happening. ——在think后面不可以加上it,这是嵌入式名词性关系分句。researchers think 为嵌入部分,可以省掉不说,what is happening 为名词性关系分句,what 作句子主语。关于嵌入式名词性关系分句,就是在名词性关系分句中加上一个“主谓结构”(researchers think),让what is happening 做其宾语,但位置放在what 之后。例如:
1. Say what you think is most urgent. 拣要紧的说。《新英汉大辞典》 2. Just do what you think is right.《牛津词典》 3. This is what he thinks is important. 【分析第三句】what is
important 是 he
thinks的宾语从句。what=the
thing which, 所以本句等于: This is the thing which he thinks is
important. 这就成了嵌入式定语从句了。
