No. 5 Tenses (2)一现在完成进行时:1. 现在完成进行时与现在完成时的延续性用法没有明显的区别,表示动作开始于过去并一直继续在进行。常与for, since等表示一段时间的状语连用,有时也用包括现在在内的段时间状语(如all day/week/year, these weeks/years, the whole morning)。The boys have been watching television since seven oclock. 孩子们从七点起就一直在看电视。I have been reading this book for 2 weeks, but I havent finished it yet. 这本书我已经看了两周,但还没有看完。2. 表示过去到现在一直重复发生的动作:I have been telling you many times that you must be more careful with your work. 我讲过多少遍了,你对自己的工作一定要更加小心。二过去完成进行时:表示过去某时以前就一直在进行的动作。它与现在完成进行时相似,但只是适用于过去的场合。如:She asked me what I had been doing these years.她问我这些年一直在干什么。When I got to the meeting, he had already been speaking for half an hour. 当我到达会场时,他已经讲了半个小时了。三将来完成进行时:表示一个持续至将来某一时间的动作。如:I shall have been teaching in this university for twenty years by the end of the term.到学期末我就在这所大学执教20年了。四将来进行时:表示将来某时刻正在进行的动作,其用法与一般将来时没有 太大区别,故较少用到。What will you be doing this time tomorrow? 明天这个时候你会干什么?五将来完成时:1表示在将来某时之前,一个动作将要发生并完成,句中常有by和by the time (that)引导的时间状语。By the end of the century China will have become a strong and prosperous country.到本世纪末,中国将成为一个繁荣富强的国家。2这个时态还可以表示可能性或推测,其作用相当于“must+ have V-ed2”结构。 如:Its five oclock.
