1．(2013·呼和浩特二调)We are so sorry for that. We'll try to determine exactly ________ went wrong that evening.
A. whose B. what
C. which D. how
答案与解析 B 句意：我们非常抱歉。我们将努力去判断那天晚上到底是什么出错了。what相当于the thing that，作determine的宾语，且作went wrong的主语。whose只作定语； which作连接代词； how作状语，均不符合题意。故B项正确。
2．(2013·河北质检二)Miodrag Soric writes that if America wants to understand ________ the world has become less safe since 9·11, it needs to look inside.
A. where B. when
C. why D. while
