我知道when是可以接暂时性动词的,但是when没有比较的意味。 做语法题也做到过前后两个都不是延续性中间用while的,老师说是因为要表示“同时进行”的意味,when强调不出这个感觉,也觉得有理。 比如说这样一个句子,He was about to leave ( ) I walked into the room. 个人认为用while是可以的。但是答案给的是when。 请高人指点一下while到底是怎么个用法。看了别人说的也觉得不是很对。
He was about to leave ( ) I walked into the room. 用when 表示正要做什么事情就在这时发生了一件事
while的意思是“在……同时(at the same time that )”“在……期间(for as long as, during the time that)”。从while的本身词义来看,它只能表示一段时间,例如: 1、He was watching TV while she was cooking. 她做饭时,他在看电视。( 同时 进行) 2、The south have rice while the north have bread(对比). 3、 He asked me a question while I was speaking. 我在讲话时,他问了我一个问题。(在...期间发生)
