Question

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．a(chǎn)s

B．it

C．which

D．this

Answer 1

A

句意：正如人們所發(fā)現(xiàn)的那樣，許多語言學習是在生命的第一年進行的，所以在那個時期父母應(yīng)該多跟孩子說話。考查非限制性定語從句中關(guān)系代詞的選用。根據(jù)句子結(jié)構(gòu)可知，空格處為非限制性定語從句的引導(dǎo)詞，先行詞為一個句子(即A lot of language learning is happening...)，先行詞在定語從句中作主語。當定語從句為被動語態(tài)時，常用as作主語來引導(dǎo)定語從句；如果從句中行為動詞是主動語態(tài)，一般用which作主語。故答案為A項，as意為：正如。
