语法专练十一 定语从句
高考真题
1.(2012·安徽高考)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
解析:as和which都可以引导非限制性定语从句,代表整个主句或者主句的部分内容。as 意为“正如,正像”,位置比较灵活,位于主句的前面、中间或者主句的后面都可以;which意为“这件事”,一般位于主句的后面。句意:正如被发现的一样,大量的语言学习发生在生命的头一年,因此在那个阶段父母应该多和孩子交流。由句意可知,A项符合题意。
答案:A
2.(2012·北京高考)When deeply absorbed in work, ________ he often was, he would forget all about eating or sleeping.
A.that B.which
C.where D.when
解析:which引导非限制性定语从句,且在从句中作表语,代替整个主句的内容。句意:“通常情况下,当他沉浸在工作中时,他会忘了吃饭和睡觉。”
答案:B
