"Where ----you put the ruler?I cant't see it anywhere." "I put it right here.but now it is ----."

问题描述:

"Where ----you put the ruler?I cant't see it anywhere." "I put it right here.but now it is ----."
A.have;gone
B.did;missed
选哪个?为什么?

A
第一句通过句意判断是发生在过去的事情,而“I cant't see it anywhere”一句说明首句描述的事情对现在有了影响.所以确定是现在完成时.
gone不只是go的过去分词形式,也有它本身的形容词意思:找不到的,丢了的
故选A
