●现在完成时的用法:
(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。
I have already read Journey to the west.
I have returned the book to the library.
●现在完成时的时间状语: (1) 用副词already和yet。already一般用于 肯定句中, yet一般用于否定句和疑问句中。
join, die, open, close, become, begin, start, borrow, stop, marry 因为它们所表示的动作是 一时的, 不能延续的, 故不能与for …, since … 等表示一段时间的状语连用。不过,瞬间动词的否定式 是可以与表示持续的时间状语连用， 即动作的不发生是可以持续的。
