题目内容
6.-How long do you suppose it is ________he arrived here?-No more than half a week.( )
A. | since | B. | before | C. | after | D. | when |
分析 -你认为他到这儿多久了?
-不超过半个星期.
解答 答案A.
do you suppose 是插入语,可以不作句子成分分析,去掉后观察主句和从句的时态可以看出:从句用的是一般过去时,而主语用的是一般现在时,所以只能用since引导时间状语从句,句型"It is+一段时间+since…",since从句中使用一般过去时态,意思是"自从…到现在多久了".如果对"一段时间"提问,句子就会变成"How long is it since…",故答案选A.
点评 本题考查从属连词的用法.连词的用法辨析,要注意分析主从句之间的逻辑关系,再确定相应的连词,同时注意不同的连词的语义及用法区别.
