Question

6.  ( 2014 广东广州，25, ★★★) I don't understand       such a silly question in class yesterday.

   A. why did John ask   B. why John asked

   C. why is John asking   D. why John asks

Answer 1

6.B句意:我不明白为什么约翰昨天在课堂上问了一个如此愚蠢的问题。本题考査宾语从句的用法。首先宾语从句应用陈述句语序,故排除A和C;再根据后面的时间状语yesterday 可知此处应用一般过去时。故B项正确。
