六、too…to…有时可表示肯定意义

在以下几种情况，too…to…结构可以表示肯定意义，而不是否定意义：

1. 当不定式前有否定词修饰时。比较：

He is too foolish to understand this. 他太蠢，不会明白这一点。

He is too clever not to understand this. 他太聪明，不会不明白这一点。

2. 当副词too的前面有否定词修饰时。如：

Never too old to learn. 活到老学到老。(直译：永远不会太老而不能学习)

3. 当副词too后面修饰的形容词是glad, ready, pleased等表示“积极”意义的词汇时。如：

I’m too glad to see you again. 又见到你我很高兴。

We are too ready to help you. 我们很乐意帮助你。

I shall be only too pleased to get home. 我要回到家里就非常高兴。

注：这类句子中的too通常含有very之意，且too前通常会有only, just等副词修饰。
