when 一定是过去完成时吗

when 一定是过去完成时吗

不一定。根据不同语境可以用
1，过去完成时：The plane had taken off when I arrived at the airport.
2,一般现在时：Please give me a call when you have further information.
3,一般过去时：My father went out when I came back home.

要根据主句的时态来判断。主句过去完成时态；从句一般过去时态。需要说明的是no sooner than 。不是then 如 no sooner had he received the letter than he called maria.

不一定的。 when 根据需要可以用于各种时态。 例如： When will your father come back?（一般将来时） When did you buy your computer?（一般过去时） I was watching TV when my father came back.（过去进行时） The film had been on for half an hour when we arrived at the cinema.(过去完成时) 祝你开心。
