when 比较简单一些。与中文里的意思相似,when 表示“当。。。的时候(一般过去时; 通常放在句首),。。。正在做什么/正在发生(过去进行时)。比如:When I entered the room, she was watching a movie on TV.
但 while 就不那么简单了。 它可放在句首,也可放在句中,由它引导的从句可以是一般过去时,也可是过去进行时。如何正确使用while的时态,要根据所表达的动作是一般过去还是过去进行。 比如:对于中文以下的句子如何翻译?
当我们在等他时,他却躲在阁楼玩电脑游戏。有几种译法:While we waited for him, he was hiding in the attic playing computer games/ While we were waiting for him, ..../He was hiding in the attic playing..., while we were waiting for him.
希望对你有帮助,有问题再问。
