一道英语情景对话题
Speaker A:Have you found your book yet?Speaker B:I am not sure____.A.where is it now B.where have I put it C.what I have done with it D.what I did about it我是在选项C 和D之间纠结,
答案给的C,用完成时没错,但选B一定错,

A："have” “yet表明完成时,“到目前为止有找到你那本书么?”
B：我不确定我把它（）了.
（）的动作是已经完成的,且对现在有影响,所以是现在完成时,B对
选项D中did表示过去某个点上做的事,强调那个时间点
再问：现在完成时是没错，但是它用的疑问语序，所以不对，你再想想看。
再答：对哦~！想明白了。就好像I'm not sure what you mean.是陈述语序。谢谢哈
