A. | before | B. | when | C. | since | D. | after |
分析 -我的儿子,你看起来怎么不开心啊?
-我想知道还要多久我们才能再来中国.
解答 答案:A
该题考查before引导状语从句的用法,句型为"It will be+时间段+before从句"表示"再过多长时间才会做某事".when当…时候;since从…开始;after在…之后.故选A.
点评 不定代词的用法较多,是一个比较难的语言点.常用的有:some(something,somebody,someone),any(anything,anybody,anyone),no(nothing,nobody,no one),every(everything,everybody,everyone,),all,each,both,much,many,(a)little,(a)few,other(s),another,none,one,either,neither等.学习时,要注意区分和掌握.
