问题描述:

用正确的动词形式:I (read) this story before.But I (now know) the write.

read know

have read 很明显的有before 就应该用完成时
后面那句我觉得有点问题,楼主你是不是打错了?
我觉得应该是“我以前读过这个故事,但是不知道作者”
也就是 i have read this story before.But i dont know the writer.
如果真的是你给的句子,应该就是now know 了 原型

have read
don't know

read(过去式)
know(动词原形)

read know
