四种完成时态
四种完成时态▲完成时态的构成▲现在完成时态的基本用法1. 表示一个过去发生的动作对现在产生的结果和影响。
应该明确现在完成时态属于现在时态的范畴。
它所强调的不是过去发生的动作，而是对现在产生的结果和影响。
否则用一般过去时态就够了。
请看下面的对话。
●A－We will send some one to America.我们要派一个人去美国。
B－I have been there.= I was there and I know the country very well. Would you send me there?C－I have not been there.= I didn’t go to America. It is my turn.上面对话的前提是大家都抢着去美国。
所以B用现在完成时态是想说明自己有经验，派他去好。
而C用现在完成时态是说自己没去过，轮也该轮到他了。
两句都是强调对现在产生的影响。
反过来，如果大家现在的目的不同，“对现在的影响”也可以不同。
Did you have lunch?Have you had lunch?Did you study English?Have you studied English?Laochang died?Laochang has diedWho was here?Who has been here?Have you done your homework2. 表示过去发生的动作一直持续到现在。
通常用于持续性较强的动词，例如：live, study, wait for, be等等，并且常常与since, for连用，since给出的是过去的一个时间点，如since 1958, 而for往往给出的是一个时间段，如for three years。
●He has studied English for eight years.●Since1980, they have known each other.注：完成时态表示延续的用法不可跟非延续动词连用，如：die, go, leave, receive等。
