notice

下面这个句子有两种不同的含义:

I'm afraid,I have to give you notice.
我不得不通知你,我要辞职了。
我不得不通知你要你离职。

notice sb to-v, notice sb v-ing, notice sb v-ed

notice后可接由动词不定式、现在分词或过去分词充当补足语的复合宾语,但表达的意思不相同。接动词不定式或过去分词表示“注意到某人做了某事”; 而接现在分词则表示“注意到某人正在做某事”。试比较:
I noticed someone go into the office.
我注意到有人进了办公室。
I noticed someone going into the office.
我注意到有人正在进办公室。
I noticed the watch lost.
我注意到手表不见了。

notice, attend, heed, mind, note

这组词都可表示“注意”或“详细观察”。它们的区别在于：
1.mind强调“用心”“全心全意”,多用于祈使句中。例如:
Mind that you don't forget to tell him.记住,别忘了告诉他。
Mind out, there's a car coming.小心,一辆汽车开过来了。
2.attend指把注意力集中在某事上而不分心、不走神,常后接介词to。例如:
Peter attends school, but doesn't attend to his lesson.彼得上学去了,却没认真听课。
He attended to his business.他专心于他的事务。
He didn't attend to the point you spoke of.他没有注意到你说的要点。
3.heed强调注意某件事的过程,是正式用语,多用于书面语。例如:
If she heeded what the teacher told her, she might make better progress.如果她多留意老师对她说的话,她也许会有更大的进步。
She countered that her advice had not been heeded.她反驳说她的建议未被重视。
4.notice指偶然一眼无意识地注意到了某个细节,而此细节对一些大的格局来说可能很是重要的。例如:
He slipped away when we were not noticing.我们没注意时,他就溜走了。
He didn't notice you when you passed by.你走过时,他没有注意到你。
I noticed with great satisfaction that you made great progress.我很满意地看到,你取得了很大的进步。
5.note既可像notice那样觉察到某个细节,又可像attend, heed那样付出注意力,专心于某事,多用于祈使句中,且语气较强。例如:
The president's every word was noted down.总统的每句话都被记录下来。
Note how I do it, then copy me.注意看我是怎么做的,然后照着做。
Note when the machine will stop.注意这台机器什么时候停。
