I can't find my pen yet;in fact,I am not sure__I could have done with itA.whereB.what选B,A为什么不对呢?
i could have done (what) with it 我对我的笔到底做了什麽 这里的什麽是what
而不是问把它放哪儿了所以不用where
如果是where 应该是where i could have put it之类的 句子里缺什麽 什麽可以带入到句子中 就用什麽

首先要搞清楚句意和从句中缺了什么成分
句意大概是：我还没有找到我的钢笔，事实上，我不太确定我对它做了什么
从句中缺的是done的宾语，where只能做状语，所以不选A

空中词作done的宾语，where不可以，
我找不着我的钢笔了，事实上我不确定我可能拿它做了什么

我找不到我的笔了.我无法确定我曾用它做什么了
从句缺少宾语 i could have done () with it
what 可以在从句中做宾语
望采纳!
