Question

我爸爸已经工作了25年了
你学英语有多久了?
他自上中学就买了这辆自行车
这本书我已读了一个月了
这星期他已经去过图书馆三次了

Answer 1

1. 我爸爸已经工作了25年了。
-> My father has been working for 25 years.
析：已经工作，工作这个动作是有延续性的，所以用现在完成进行时

2. 你学英语有多久了?
-> How long have you been studying English?
析：study这个动作也是一个延续性动词，学了。。。多长时间，是一段时间中从以前到现在都在学，所以用现在完成进行时

3. 他自上中学就买了这辆自行车。
-> He has been having this bike since he entered middle school.
析：buy这个动词是一次性动作的动词（购买，不能说一直买买买），所以要改用have（有）这个持续性动词，用现在完成进行时原因同上。

4. 这本书我已读了一个月了。
-> I have been reading this book for a month.
析：read是个延续性动作动词，从说话以前的时间开始读，读到现在还在读，动作还在进行，用现在完成进行时。

5. 这星期他已经去过图书馆三次了。
-> He has been to the library for three times this week.
析：go去去去去一直在去的话就是没回来，去过说明已经回来了，所以要改用持续性动词be to，用现在完成进行时理由同上。

Answer 2

My father has worked for 25 years.
现在完成时，for+一段时间

How long have you learned English?
现在完成时

He had had the bike since he studied in middle school.
主句用过去完成时，从句用一般过去时
buy要转换成延续性动词（had)

I have read the book for 1 month.
现在完成时

He has been to the library 3 times this week.
现在完成时
has been to表示去过已经回来了本回答被提问者采纳

Answer 4

My father has worked for 25 years.
How long have you learned English?
第三句有点问题，买是个瞬间动词，应该不能搭配“自”吧
I have read the book for one month.
He has been to the library three times this week
