what是个连接代词“所...的事物”,它在从句中作了could have done的宾语；而 whether是连词,不能做宾语,并且词义是“是否”,也不合适.
是“我不确定我把它怎么了
I have not found my book yet; in fact ,I am not sure__I could have done with it .明白选what
I have not found my book yet; in fact ,I am not sure__I could have done with it .明白选what
为什么whether不行?我还没找到我的书,我不确定是否我把它处理了.不可以么?
I am not sure what I could have done with it ."我不知道该怎么办"还是“我不确定我把它怎么了?”
