Question

【题目】 (2012·安徽) 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.

A. as

B. it

C. which

D. This

Answer 1

【答案】A

【解析】本题考查定语从句的引导词as用法。关系代词as指a lot of language learning is happening in the first year of life。如用which引导，则需要置于主句末尾。句意：正如被发现的那样，大量的语言学习是在人生的第一年发生的，所以父母应该在那个时期和孩子多说话。
