I have been sitting in front of the monitor too long.
这是卷子上的句子,我的问题是为什么too long前面不用加for?如果是可以省略的话,for在哪些情况下是可以省略的?
还有一道题：You said you had seen her with him,____ you?
标答是hadn‘t you?
我的疑问是：原句中的动词不是said吗?had只是从句中的动词啊?那反义疑问句不是应该是didn’t 很纠结………………

第一句话楼上回答正确,不累述了.
至于第二句,包含主句和宾语从句.
主句是：You said XXXXXX
宾语从句是：You had seen her with him.
对主句or从句提问要看表达的意思.如果表达“难道你没说过吗?”就对主句提问didn't you.表达“难道你没看到过吗”就对从句提问hadn't you.
这里应该是对从句提问,从句主语是you,助动词是had,形式为肯定,所以反义疑问形式为hadn't you.
这种“对从句进行反义疑问”的用法经常出现在以I开头表示个人看法意见的复杂句中,常见的主句形式有I think,I suppose,I believe,I guess,I reckon等.比如
I don't think she's good at it,is she?
但是从你的问题可以看出其他情况也是有此用法的.
哥走了,给分.
