2个回答

1. 现在完成时:I have passed the exam.

2. 过去完成时:He told me he had passed the exam.

3. 将来完成时:I will have passed the exam by the end of next year.

4. 过去将来完成时:I would have passed the exam if I did not have that medical operation.

完成进行时在高中应该会,以现在完成进行时为例:

I have been learning English for almost six years.
