语法专练十 名词性从句
高考真题
1.(2012·安徽高考)The limits of a person's intelligence, generally speaking, are fixed at birth, but ________ he reaches these limits will depend on his environment.
A.where B.whether
C.that D.why
解析:句意:一般来说,一个人的智力极限在出生时就确定了,但是能否达到这些极限却依赖后天的环境。where和why引导名词性从句时,在从句中分别作地点状语和原因状语;that引导名词性从句时,在从句中不作任何成分,也无词义;whether引导名词性从句时,意为“是否”。故只有B项符合题意。
答案:B
2.(2012·湖南高考)Everyone in the village is very friendly. It doesn't matter ________ you have lived there for a short or a long time.
A.why B.how
C.whether D.when
解析:分析句子结构可知,it作形式主语,真正的主语是其后面的从句。句意:村里的每个人都很友善,你在此居住的时间长短没有关系。根据句意以及从句中最后的or a long time可知,此处C项正确。
答案:C
