We even put up a notice to check whether someone happened to find it,
but it was in vain.这是在一篇作文范文中看到的一个句子。这个句子中的 whether someone happened to find
it 是不是应该改成 whether someone happened to have found it 啊?请教各位专家老师。
副词 never 通常是应该放在系动词be之后。比如下面的句子都是出自一本语法书:He is never behind with his work. 他工作从不拖拉。The house was never clean nor tidy. 房子从不干净,也不整齐。She was never too proud to learn. 她从来没有骄傲得不去...
...在完成时haven't吗?didn't只能用在must have done表一般过去时的非被动语态里吗?
She must have been there yesterday, didn't she? 这里可以用wasn't she吗?wasn't/weren't只能用在must have been done被动句里吗?
请老师分析一下类似以下句子的意思以及句子成分:
Not a day passes but we use electricity in our daily life.
Not a day goes by when I don't think of my old friend Jim Green.
谢谢老师!
