be such as to do sth是什么结构（它完整吗）

问题描述

在答疑网看到这么一句：
His bad behaviour was such as to anger everyone.
总感觉 such 后面好像少一个形容词，是这样的么？

老师答疑

曾老师：

这里的such是代词，指 His bad behaviour。

见《牛津高阶英汉双解词典》：

(b) such as to do sth; such that ... (referring forward 用以预指後文): 

The pain in her foot wasn't such as to stop her walking. 她脚疼, 但还不至於不能行走。

The damage was such that it would cost too much money to repair. 损坏得很严重, 要用很多钱才能修好。

▲《牛津英语用法指南》解释说：

such后面跟 ... + as to + 不定式。这个结构很正式。且不常用。

It was such a loud noise as to wake everybody in the house. 声音这么大，屋子里的每个人都给吵醒了。

（不太正式的说法：...such a loud noise  that it woke ...）

蒋老师：

同意曾老师的分析。不过这个问题也可从另外一个角进行比较简单地处理，即将 be such as to do sth 作为一个句型来看待，用于表示某情况的程度很深从而导致了某种结果（通常为不良后果）。如：
His indifference is such as to make one despair. 他如此冷淡，令人感到绝望。
His illness was not such as to cause anxiety. 他的病情并未糟到令人担忧的地步。
The pain in her foot wasn’t such as to stop her walking. 她脚疼，但还不至于不能行走。
His bad behaviour was such as to anger everyone. 他的表现很糟糕，让每个人都很生气。
