A解析试题分析:考查单词意思,plex意思“复杂的”cautious意思“小心的”,difficult意思“难的”,eager意思“渴望的”, mixed意思“混合的”,careful意思“小心的”,mild意思“温柔的”,anxious意思“担心的”,句子意思“中东的形势如此复杂以至于我们处理人质问题的时候不得不小心”,所以选A考点:考查单词意思点评:注意so…that…的用法,so+adj/adv+that…;such a/an+adj+that…。当先行词是situation,引导词用where,固定句型deal with意思“处理”, the hostage issue意思“人质问题”,句子when dealing with the hostage issue,是when引导的时间状语从句。注意have to和must的区别,have to表示因外因而不得不;must表示因内因而不得不。
