Answer 1

知识要点 ,状语从句是副词性从句，它在句子中担任状语，修饰主句的动词、形容词或副词。根据修饰的方面，状语从句可以分为以下九种：时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句、条件状语从句、方式状语从句、让步状语从句和比较状语从句。, 一、时间状语从句 ,指的是“某一具体的时间”。whenever指的是“在任何一个不具体的时间”。
When I came into the room, he was writing a letter.
当我进屋时，他正在写信。
We shall go there whenever we are free.
我们什么时间有空，我们就去那里。,意为“这时”或“在那个时候”，可以看作是并列句,这种用法的when分句一般位于句末。
I was walking along the street when suddenly someone patted me on the shoulder from behind.
我正在街上走着，这时忽然有人从后面拍我的肩膀。,e指“在某一段时间里”，“在……期间”，while引导的动作必须是持续性的。
While it was raining, they went out.
天下雨的时候，他们出去了。
