英语六级-完形语法关键句391. Doctors are often caught in a dilemma bec

391. Doctors are often caught in a dilemma because they have to decide whether they should tell their patients the truth or not.

译文　医生常常进退两难，因为他们得决定是否应该将患者的真实病情告诉他们。

点睛　dilemma意为“两难的境地”，它通常用在短语（be caught）in a dilemma或者between dilemma and the deep blue sea中。如：

She was in a dilemma as to whether to stay at school or get a job. 她进退两难，不知该留在学校读书还是找份工作。

考点归纳　whether通常与or not搭配使用，表示“是否……”，但是or not也可以省略。如：

You are entitled to a free gift whether you accept our offer of insurance or not. 无论你是否接受我们的保险提议，你都可以免费得到一份礼物。
