1、-初中英语现在完成时用法归纳-第 2 页优胜教育现在完成时1、用法: 用于表示“过去发生的动作对现在造成的影响或结果”。强调对现在造成的影响或结果,常与 “ever/never/already/yet/just”连用。如:She has gone to Shanghai. She is not here. 用于表示“过去开始的动作一直持续到现在”。强调动作的持续性,常与“for/since+时间”连用。 如: I have lived in Kunming for ten years.2、时态标志词:for/since+时间,just,never,ever,already,yet,before
2、,so far,in the past/last few years等。3、常考易错点:(1)辨析have gone to,have been to与have been inhave/has gone to:“已经去了某地(去而未归)”去了某地还没回来,常用来回答where开头的问句have/has been to:“曾经去过某地(去而已归)”去过某地但已回来,常与ever/never/次数(two/many times)连用。have/has been in:“在某地待了(多长时间)”,常与 “for/since+时间” 连用。 He is not here. He has gone to

(2) 现在完成时与一般过去时的区别:时态类别用途构成时态标志例句一般过去时强调动作发生在过去(但不强调对现在造成的影响)。动词用过去式表“过去时间”的词或短语:yesterday, last night, two days ago, just now,in 2010I lost my English book yesterday.现在完成时强调过去发生的动作对现在造成的影响have/has +过去分词already,yet,

I have kept the book for a week. I bought a car last year. I have had the car for a year.
