2、edlived,studiedcarried,stoppedplanned,hadkept,1 现在完成时的主要用法及常用时间状语 a 表示过去发生或已经完成的某一动作对现在产生的影响或结果，常与already、never、ever、just、yet等时间状语连用。Then make your own sentences like this:eg：I have already done my exercise.b 表示过去已经开始，持续到现在的动作或状态，可以和表示过去某一时刻延续到现在（含“现在”）的一段时间的状语。如：today、these days、for two years、since
3、 1984、since he came here等连用。2 巧记现在完成时的用法 学习现在完成时，谓语结构要记住“have/has+过去分词”主要用法有两个：过去发生的动作对现在产生的影响或结果，just，already常用着，过去动作或状态，一直延续到现在，for和since把时间带。如：I have known Lilei for three years.Now，boys and girls，tell us your sentences like this-,现在完成时/The Present Perfect Tense,试一试，用所给词的正确形式填空1 I（live）here since
4、 I was ten years old.2 I（live）here in 1998.-you your breakfast？-Yes，I have.-When you it？-30 minutes ago.,注意现在完成时的几个特殊方面：（一）现在完成时与一般现在时的区别,have lived,lived,Have,had,did,have,现在完成时表示过去发生或已经完成的某一动作对现在产生的影响或结果，强调的是现在的情况。所以它不能和表示过去时间状语连用；而一般过去时只单纯表示过去的动作或状态，和现在不发生关系，可以和表示过去的时间状语连用。一）现在完成时与一般现在时的句型转换eg：I
5、have studied English for three years-I studied English three years ago-It is three years since I studied English,（二）表示短暂动作的瞬间性动词，如come、go、buy等的完成时态就不能与for、since 等表示一段时间的状语连用，但可以与这类词相应的延续性动词或短语连用。试一试，改错 1 I have come to Jianyang for ten years.（）2 His father has died since he was five years old.（）,hav
6、e been in,has been dead,瞬间动词的用法口诀；现在完成在瞬间，非延只连时间点，终止 须转换，否定方可碰一段说明：1 瞬间动词又叫非延续性动词或终止性动词，它可以有现在完成时态，但不可以接一段时间；如果要接一段时间，就必须把它转换成相应的延续性动词。2 瞬间动词在完成时态中的否定式中可以接一段时间。,类似的转换还有：fall asleepbe asleep move therebe there open be open 等,巧记10个瞬间性动词的转换“开始离去借来还，出生入死买到家”,have/has been to和have/has gone to 的用法区别,1“Hav
7、e/has been to+地名”表示曾经去过某地，说话时已经回到说话地点，常与once、twice、ever、never 等时间连用。2“have/has gone to+地名”表示去某地了，现在没有回答，人不在说话地点。巧记：been to，gone to 意不同，两者用法要记清；have been to+地名，曾经到过某地行；have gone to+地点，到某地去了一走远。,用have/has been to和have/has gone to填空 Hi，Lucy，you ever Beijing？No，I.What about your sister，Lily？Oh，she Cheng
