I bought this book two years ago我买了这本书在两个星期之前.那为什么不可以在bought前加have.
I bought this book two years ago我买了这本书在两个星期之前.那为什么不可以在bought前加have.

I bought this book two years ago我买了这本书在两个星期之前.那为什么不可以在bought前加have.
buy ,买,是个瞬间动词,交出钱的那一刻,就是买了
而且有了 two years ago,两年知用过去时,
所以果断用bought
亲,若是用了have bought,则表示一段时间里（这里特指2年）,一直在进行着这个动作
你想想啊,我总不能一直在——进行“买”这个动作吧
所以,比较合适的用法是,
i have had （拥有,连续性动词）this book for two years.

two years ago 有具体的过去时间，而且买是瞬间动作，不可以用完成时的。

two years ago意为两年前在这可以看出，是过去式的。
懂了吗

two years ago 过去时态的标志

bought 是短暂性动词.前面不能加have ，还有two years ago说明是一般过去时.不能加have。
如果要加，应该这样说：I have had this book for two years

(合并一句)This is the book I two days ago 2.21I have bought this story book for more than ten years.have bought 错了应该改为?为什么? this is the book that i bought it yesterday 为什么去掉it ? morning,book,is the ,this,I,where,bought,which连成一句话 I bought you this book _____ americaA from B for C to 高分求助 I bought you this book about China.（改为同义句）
