从situation作先行词谈一类定语从句的引导词

从situation作先行词谈一类定语从句的引导词首先请看2001年高考上海卷中的一道单选题：
1.Hes got himself into a dangerous situation _______ he is likely to lose control over the plane.
A. where
B. which
C. while
D. why
当situation 作先行词时后面的定语从句引导词有如下两种情况：
1. 引导词在从句中作主语或宾语时, 引导词用 that / which 作宾语时, 引导词可省略。

eg. Worrying never helps in a situation ( that / which ) you can’t change. 对于你无法改变的状况，发愁于事无补。

（引导词在句子中作宾语）
2. 引导词在从句中作状语时，引导词可用where 或 in which / at which 。

与situation用法类似的名词有：condition（s）（条件、状况）；spot（地点）；place (地方)；position（位置）；stage（阶段）；case（情形、例、病例、案例）；point（点、程度、）；business（企业、事业）；meeting（会议、集会）；earth（地球、世界）；society (社会)； world (世界) ；surroundings（环境）等。
