notice
1.比较下面各句：
- It is difficult to obtain so much data at such short notice.（1.在这样短时间以前通知要得到这么多资料是困难的。2.限期这样短而要这么多资料，这是难于办到的。）
- I have to give you notice.（1.我不得不通知你，我要离去了。2.我不得不通知你，要你离去。）
- I have notice.（我已经被通知要我离去。）
- I have given him notice to quit.（我已经通知他要他离去。）
- You are to stay here till further notice.（你该留在这里直到下次通知为止。）
- They went away without (previous) notice.（他们并不预先通知而离去了。）
下面几点该注意：
（1）at short notice, at such short notice, at a few hours' notice等表达方式里的at在美国有时改用on。
（2）give notice或have notice后面加上了不定式，在notice前面有时有a。例如：He gave me a notice to leave by the end of the week.
（3）give notice和have notice里的notice通常指关于离去（如离职或迁让）的“通知”，但在说明其他动作的场合便指其他动作。例如：I have notice to send in my report within three days.
2.give notice后面可以接以that引导的从句。例如：The tenant gave notice that he was going to move on the first of the next month.
3.notice（无意间注意到）的宾语后面的不定式没有to。例如：I noticed a boy come out of the house.但假使把notice改作被动语态，那不定式便该有to。例如：A boy was noticed to come out of the house.
4.下面两句意思略有不同：
- I noticed a boy come out of the house.（我无意间注意到一个男孩从房子里出来。）
- I noticed a boy coming out of the house.（我无意间注意到一个男孩正在从房子里出来。）
第二句着重在那男孩的正在出来而恰巧被我看见。下面各句里的现在分词最好不改作不定式：
- He noticed a little girl standing at the door.
- She noticed a stranger looking up at the window.
- They noticed a group of boys waving to them.
- Did you notice the baby talking to the doll?
5.下面两句里的notice(d)后面都接以that引导的从句，但意思不同：
- He noticed（无意间注意到）that the girl was somewhat lame.
- Please notice（注意）that the physical examination will take place tomorrow morning.
