　［正］ Not getting enough sleep is harmful to your health.
　由于不知道发生了什么事，他像往常一样去上班了。
　［误］ Having not know about the accident, he went to work as usual.
　［正］ Not having known about the accident, he went to work as usual.
　［析］ 非谓语动词的否定形式在前面加not.

3. 学生们举行罢课，但老师们没有举行罢教。
　［误］ The students went on strike, but no the teachers.
　［正］ The students went on strike, but not the teachers.
　［析］ not和no均可用来构成否定，但用法不同。not用来使动词变成否定，而no是作为形容词用在名词前，意思是not a或not any.
4. 我两个都不要。
　［误］ I don't want both of them.
　［正］ I don't want either of them.
　［析］ either用在not后面，表示全部否定，而not与all, every, everyone, both等词连用时表示部分否定。
5. 我几乎不能相信这事。
　［误］ I cannot almost believe it.
　［正］ I can hardly believe it.
　［析］ “几乎不”用hardly, scarcely表达。almost可以修饰no, none, nothing等词，但不能修饰not.
6. 他总是不迟到的。
　［误］ He is always not late.
　［正］ He is never late.
　［析］ always not表示“不总是，有时不”，不符合句意。
7. 他一点也不像他父亲。

　［正］ Not only did he make a promise, but also he kept it.

10. 他不该这么早就开始。
　［误］ He should have not started so early.
　［正］ He should not have started so early.
　［析］ 在复合谓语动词中，副词not, never等通常放在第一个助动词之后。
11. 他不像你那样强壮。

　［误］ The boss was on holiday, but no the employees.

　［误］ He didn't speak clearly and correctly.
　［正］ He didn't speak clearly or correctly.
　［析］ not...or表示全部否定， not...and表示部分否定。
