现在完成时
用法索引
1.表示过去发生或已经完成的某一动作对现在造成的影响或结果。常用的时间状语:
already,get,never,just,before,recently,for+一段时间,since+一段时间
I have lost my key.(说明过去某时丢的,现在还未找到。)
2.表示过去已经开始,持续到现在的动作或状态。
I have known him for ten years.
The dog has been dead for three days.
3.表示从过去到现在之间曾经经历过的事。
We have been to the Summer Palace twice.
请你注意:
因为含有for加一段时间或since加一个时间点这样的时间状语的完成时,有动态和延
续性的特点,所以不能使用终端动词或瞬间动词。
例:My sister has been here for 5 days.(过去分词做表语表示状态,可以延续)
My sister came here 5 days ago.(终端动词)
