陈述部分含有too（太）反意疑问句用肯定还是否定

问题描述

如果陈述部分含有 hardly, seldom, scarcely 等否定副词时，后面的反意疑问句要用肯定式。如：

I’ve never let you down, have I? 

She’s never had her appendix out, has she? 

You seldom see that sort of thing these days, do you? 

She can scarcely speak the language, can she? 

但如果陈述部分含有副词 too（太）呢？反意疑问句是要用肯定式还是否定式。如：

He is too old, ______ he?

He is too old to do the work, _______ he?

老师答疑

曾老师：

当一个句子中有never, seldom, hardly, few, little, barely, scarcely, nothing, none, rarely, no, not, no one, none, nobody, neither...等否定词时，句子无论是在意义上还是在形式上都是否定的，这样的句子才是否定句。这时，如果后面接附加疑问句，通常要用肯定形式。而too并不是一个否定词，too...to 结构有时候只是在意义上表达否定，而在形式上仍是肯定的。所以，附加疑问句要使用否定式。即：

He is too old, isn't he?

He is too old to do the work, isn't he?

▲另外，too...to 结构并不总是表示否定意义的，也可表肯定的意义。如：

He was too eager to succeed.他太急于求成。

Your arguments are too easy to be cut down.你的论点一驳即倒。

We are all too pleased to listen to the opinions of other.我们非常乐意听别人的意见。
