现在完成时知识梳理和专项练习
1.现在完成时表示过去已经结束的动作对现在产生的影响：
I have already seen the film, it is pretty good.
Can you lend me your pens I have left mine in at home.
（1）常用标志词：already（一般用于肯定句）, yet（否定句表示“还”，疑问句表示“已经”）
just, lately, recently, so far, up till now, by this time等
（2）此种用法一般会考察对于语境的理解，例如：Can you lend me your pens I have left mine in at home.
2.现在完成时表示过去的某一动作一直持续到现在：
My family has lived here for twenty years.
（1）常用标志词：since+时间点， for+一段时间
（2）终止性动词和持续性动词：
终止性动词又称为短暂性动词，表示动作是短暂的，瞬间完成的，如：die, join, close, leave等
持续性动词又称延续性动词，表示动作是可以持续的。如：eat, have，keep, lie
完成时第二种用法肯定句的动词必须是持续性动词。
His father has been dead for three years. (√)
His father has died for three years. (×)
（3）常见终止性动词和持续性动词的转化：
buy---have borrow---keep arrive---stay learn--- know
come back---be back leave --- be away die---be dead begin---be on
3.现在完成时表示经历过的事情，这种经历不可能被埋没或者否定：
I have read the book three times.
（1）常用标志词：never, ever, …times
（2）have been to，have gone to， have been in
have been to表示“去过某地，已经回来了“
have gone to表示“去了某地还没有回来“
have been in表示“待在某地“，一般和段时间状语连用
4.现在完成时的动词结构为：have/has+过去分词
（1）have/has为助动词，本身无意义，
（2）规则动词的过去分词和过去式一样，不规则动词的过去分词需要逐个背诵
