完成时与过去式区别3VIP免费

三、现在完成时与一般过去时的区别现在完成时：强调过去发生的动作对现在产生的结果或影响，并不强调动作发生的具体时间。它的时间状语不是具体的时间点，所以不用when 提问，而用 how long 提问。一般过去时：讲述的是发生在过去具体时间的事情。现在完成时的标志词或短语有： already, yet, never, just，ever, before, for+时间段，since+时间点，in the last…. 而过去时的标志词有：yesterday, last year, ago, just now, just before, in 199, this morning 等。要注意时间状语所表示的时态。巩固练习 用括号内单词适当的形式填空。1.I_________Beijing before (be), I ______there two weeks ago.(go)2.
