22、nown each other since childhood.他们从小彼此相识。（现在还继续往来）How long have you studied English？你学英语多久了？（现在仍在学）由以上例句可以看出，在表示行为或状态从过去一直持续到现在时，要与表示一段时间的时间状语连用，常用的是for或since引导的时间状语。 注意 （1）.since+时间点或者从句，而for +一段时间。Since last year, since 1997. since 8 oclock am ,since five days ago . for ten years , for an hour（2）.

23、对这类时间状语提问要用how long。(但how long开始的问句动词要用延续性动词，时态可不限。如How long did he stay there?

24、each other for some days. See 为瞬间性的动词，但在否定句中也可以和some days 一段时间连用。2. 现在完成时和一般过去时的区别用法例句现在完成时现在完成时强调的是过去发生的动作对现在造成的影响或者结果，强调现在的情况或者状态，与过去没有关系。不能和表示过去的时间状语连用。I have seen the film already. (现在我已经了解这部电影的内容了，至于什么时候看的没有关系，反正我已看过了。) 一般过去时一般过去时只表示这动作是在过去某个时间发生的，或者说是过去某个时间发生了某个动作而已，和现在没有关系。可以和表示过去的时间状语连用。I sa
