137、双重否定句Nobody had nothing to eat.；
例句：I never got no sleep in those days. 那些日子我怎么也睡不着。

双重否定句最主要的功能就是通过两个否定词在句子中互相抵消其否定的含义，从而实现“否定＋否定=肯定”，加强句子的肯定语气，这样的双重否定句被称之为肯定型双重否定句。

如: Nobody had nothing to eat. = Everyone has something to eat. 每个人都有吃的。

138、look to it that... 注意；当心：务必；
例句：Look to it that you are here in time tomorrow. 你明天一定要按时到达这里。

按照英语习惯，介词后通常不能直接跟that从句作宾语，但有少数特殊结构就在介词后先接it作形式宾语，再跟that从句。

look to it that...是个特殊结构，就是在介词to后先接it作形式宾语，再跟that从句，这里的it就是指代的后面的that从句。

look to意为“注意；当心：务必”。

动词短语allow for （担保）、count on（期待）、depend on（依靠）、insist on（坚持）、see to（确保）等都有相同的用法。

139、awake to the fact that 认识到...的事实；
例句：You must awake to the fact that you have failed in business. 你必须了解你的事业已经失败了。

awake作动词，有“唤醒、使清醒、使醒悟”的意思，awake同时还是形容词。

在用法上，awake可以作及物动词，如: The music awoke my imagination音乐唤起了我的想像力。

awake也可以作不及物动词，如: You must awake to the fact that you have failed你必须清醒地认识到你失败了。

本句型中的the fact后的that从句是同位语从句。

awake to the fact that 意为“认识到...的事实”。

配套练习：
①You must _____ the fact that failure will mean disgrace.
A. awake
B. awake to
C. awaken to
D. wake to

140、be that as it may即使如此，尽管那样; 话虽如此;
例句：Be that as it may, terrible things clearly happened. 尽管如此, 可怕的事情无疑还是发生了。

be that as it may = although it may be that是一个习惯用语, 起到插入语的作用。

be that as it may意为“即使如此，尽管那样; 话虽如此”。

be that as it may 是虚拟语气。

be that 倒装表示强调虚拟对象，相当于说“就算那样吧，又能这样”。

动词原形be 置于句首本身就是虚拟语气的一种格式。
