I have read that book before。有这样的句子吗？
before是过去，以前的意思，所以应该I have read that book before这样的句子是不可以吧？
就应该是个I had read that book before吧。

过去完成时还是现在完成时,就看相对较后的时间是现在时还是过去时了.
如;
1.She told me to read it,but I I had read that book before.
(这里,told)
2.--"Read this book,Tom."
--"But I have read that book before".

两句时态是不一样的

I had read that book before.这是过去完成时！可是... I had read that book before.这是过去完成时！可是.... I had read that book before.这是过去完成时！可是... I had read the book yesterday。I have read the book yesterday I had read the book yesterday。I have read the book yesterday I had read the book yesterday。I have read the book yesterday I had read the book yesterday。I have read the book yesterday. I had read the book yesterday。I have read the book yesterday I had read the book yesterday这个句子语法正确吗？谢谢 I had read the book yesterday。I have read the book yesterday这些句子语法正确吗？请详细的说明吧
