when的意思为当……的时候,后面可跟的时态是:
when用作并列连词时的意思是“正在……，这时……突然”，连接两个并列句。例如：Wewere
doing
our
homework
when
the
light
went
out.（我们正在做家庭作业，就在那时灯熄灭了。）
引导时间状语从句，意思是“当……的时候”。例如：It
was
raining
when
we
arrived.（我们到达时天正下着雨。）
表示“何时，什么时候”，例如：Until
when
can
you
stay?（你能呆到什么时候？）
when和while引导，意思上都差不多。关键是时态搭配。
when引导的时间状语从句，一般是两个情况，一个是主将从现，比如i
will
visit
you
when
i
am
free.还有一个是从句用一般过去时，主句用过去进行时，比如i
was
reading
a
book
when
he
came.
while引导的时间状语从句，你只要保证从句用进行时就可以了，主句无所谓，当然一般主句也用进行时，比如i
was
reading
a
book
while
he
was
watching
tv.
