1、三、现在完成时态的用法 1、用来表示之前已经发生或完成的动作或状态,而其结果却和现在有联系: 动作或状态发生在过去,但它的影响现在还存在,可以和already, never, ever, just, before, yet等副词连用。例如: They have left. (他们已经离开了,也就是说现在他们人不在这里)I have had my lunch. (我已经吃过午饭了,也就是说我现在不饿)He has seen the film. So he wont go with us. (看电影发生在过去,但现在仍然记得它的内容。) already与yet都有“已经”的意思,但already常
2、用于肯定句,并用于句中。yet常用于否定句和疑问句,并用于句末。I have already finished my homework. I havent finished my homework yet. Have you finished your homework yet?2、表示过去已经开始,持续到现在的动作或状态,可以和表示从过去某一时刻延续到现在(包括“现在”在内)的一段时间的状语连用,如for+时间段、since+过去的时间点、疑问词how long等。My uncle has worked at this factory for five years. 我叔叔在这个工厂工作已经
3、五年了。Mr. Black has lived in China since 2002. 自从2002年Mr. Black 一直住在中国。How long have you been here? 你来这里多久了?注意:此种用法中表示持续动作或状态的动词必须是延续性动词(否定句除外)。(1)这本书我已经买了三个月了。错误:I have bought the book for three months. 正确:I have had the book for three months. (2)你哥哥参军多长时间了?How long has your brother joined the army?H
4、ow long has your brother been in the army/been a soldier?四、现在完成时态与一般过去时态的区别 1一般过去时表示过去某时发生的动作或单纯叙述过去的事情,强调动作;现在完成时为过去发生的,强调过去的事情对现在的影响,强调的是影响。I saw this film yesterday.(强调看的动作发生过了。)I have seen this film.(强调对现在的影响,电影的内容已经知道了。2一般过去时常与具体的表示过去的时间状语连用;现在完成时通常与模糊的时间状语连用,或无时间状语。一般过去时的时间状语: yesterday last w
5、eek, .ago, in1990,in October, just now,现在完成时的时间状语:for, since, so far,ever, never, just, yet,in the past few years, already, 句子中如有过去时的时间副词(如 yesterday, last, week, in 1960)时,不能使用现在完成时,要用过去时(错)Tom has written a letter to his parents last night.(对)Tom wrote a letter to his parents last night.3)现在完成时可表示
6、持续到现在的动作或状态,动词一般是延续性的,如live, teach, learn, work, study, know. 一般过去时常用的非持续性动词有come, go, leave, start, die, finish, become, get married等。She joined the League three years ago. (加入的动作不是延续的)She has been in the League for three years (since three years ago). (在团内的状态可延续)She has been a League member for th
7、ree years (since three years ago).是团员的状态可持续)比较since和forsince 用来说明动作起始时间 “自从”,for用来说明动作延续时间长度 “长达”。在有for 和since 引导时间状语的句子中不能用短暂性动词,应用与之相应的表示状态的词I have lived here for more than twenty years.I have lived here since I was born.My aunt has worked in a company since 1949.I have not heard from my uncle for
8、 a long time.比较 have/has been to、have/has gone to 和 have been inhave(has) been 表示“曾去过某地,已经从那里回来了”,可以和ever、never、twice等连用。have(has) gone 表示“已经去了某地,在去那里的途中或到达那里还没有回来注意:第三人称”。have(has) been in 表示“在某地呆多长时间”,常与表示一段时间的状语连用,如:since, for, how long 等He went to Shanghai last week 上周他去了上海He has been to Shangha
9、i. 他(曾经)到/去过上海.(但他人现在肯定不是在上海而是回来了)He has gone to Shanghai. 他已经去上海了.(也许刚动身出发,也许已经到了,也许还在路上,反正他人不在这里)Mr. Brown has been in Shanghai for three days. 布朗先生来上海已经有三天了一、单项选择。1、Both his parents look sad.
