　　举例：She is currently writing a book.

　　举例：

　　She has been writing books for over 20 years.

　　She has been writing books sine she was 18 .

　　四、现在完成时(I have done，she has done...)1、加行为动词的时候(已经完成的动作对现在造成的影响) 会有一些固定搭配： so far， already，not yet，recently，just，ever，never，today(until now)，this year(until now)，in the last few years，in the past week...
