(说话人认为他不在该地)He has been to Fuzhou.(说话人认为他在该地)2)现在完成时所表示的动作开始于过去,持续到现在,也许还会持续下去.常用for和 since表示一段时间的状语或 so far,now,today, this week( month,year)等表示包括现在时问在内的状语.例如:He has studied English for 5 years.He has studied English since 1985.Now I have finished the work.注意:表示短暂时间动作的词,如 come,go,die,marry,buy等的完成时不能与for,since等表示一段时间的词连用.3)现在完成时还可用在时间和条件状语从句中、表示将来某时完成的动作.例如:I’ll go to your home when I have finished my homework.If it has stopped snowing in the morning,we’ll go to the park.7.过去完成时的用法l)过去完成时由“ had十过去分词”构成.过去完成时的动词表示过去某一时刻或某一动作之前完成的动作或状态.句中常用 by,before,until,when等词引导的时间状语.例如:By the end of last year we had built five new houses.I had learnt 5000 words before I entered the university.2)过去完成时的动词还可表示过去某一时刻之前发生的动作或状态持续到过去某个时间或持续下去.例如:Before he slept,he had worked for 12 hours.8.过去将来时的用法过去将来时表示从过去的某时间看来将要发生的动作或存在的状态.过去将来时由“ should或 would十动词原形”构成.第一人称用 should,其他人称用 would.例如:They were sure that they would succeed.9.现在完成进行时的用法现在完成进行时由“ have(has)十 been十现在分词”构成,表示现在以前一直在进行的动作.有些词,如 work,study、live,teach等用现在完成进行时与用现在完成时意思差不多.例如:I have worked here for three years.I have been working here for three years.但多数动词在这两种时态中表示不同意思.例如:I have written a letter(已写完)I have been writing a letter.(还在写)注意:表示短暂动作的动词,如 finish,marry,get up,come,go等不能用这种时态.
