谢谢

1.when是at or during the time that, 既指时间点，也可指一段时间；
2.when 说明从句的动作和主句的动作可以是同时，也可以是先后发生；
3.由when引导的时间状语从句，主句用过去进行时，从句应用一般过去时；如果从句和主句的动作同时发生，两句都用过去进行时的时候，多用while引导，如：
When the teacher came in, we were talking.
题中那句话就这个句型.

时间状语从句
when the UFO arrived 是时间状语
What were you doing 是主句

意思是：飞碟来的时候你在做什么？

时间状语从句

when 引导从句, 内容是" UFO到达的时候"

时间状语从句

时间状语从句.从句在主句中做时间状语.

what were you say Do you remember what you were doing? What were you saying ___ the moment? 命题作文:if you were me,what would you do ? what would you do if you were chairman of china? what do you do when you were one solder? What were you doing when I phoned you yesterday evening? What did you _____ when you were sick? what did you go? what have you been going? what were you going? what have you gone? What's the first thing you'd do if you were going to build a house?什么意思？它是虚拟语气吗？
