5.Great changes have taken place in that school.It's no longer ___ it was 20years ago,____ it was so poor.( )A. | what,when | B. | that,which | C. | what,which | D. | which,that |
分析 那个学校发生了很大的变化,在也不是20年前的样子了,那时很破.
解答 答案:A
分析句式可知___ it was 20years ago为表语从句,从句从缺少表语,所以用what引导;____ it was so poor是一个非限制性定语从句,该从句中缺少状语,结合先行词20years ago指时间,所以第二空用when.
点评 考生需对表语从句的特点掌握并能根据具体语境选择合适的连接词.
