A lot of language learning,________ has been discovered,is happening in the first year of life,so parents should talk much to their children during that period.(2012·安徽,29)

A.as

B.it

C.which

D.this

答案

答案:A

句意:正如人们所发现的那样,许多语言学习是在生命的第一年进行的,所以在那个时期父母应该多跟孩子说话。考查非限制性定语从句中关系代词的选用。根据句子结构可知,空格处为非限制性定语从句的引导词,先行词为一个句子(即A lot of language learning is happening...),先行词在定语从句中作主语。当定语从句为被动语态时,常用as作主语来引导定语从句;如果从句中行为动词是主动语态,一般用which作主语。故答案为A项,as意为:正如。
