give a message to... 给某人一个口信
4. I'll tell her when she comes back. 她一回来我就告诉她。
本句是由when引导的时间状语从句。当主句的动词用一般将来时时，从句一般用现在时。如：
He'll phoneme when he arrives in Beijing .当他到北京时，他将回给我打电话。
5. ..., he took an active part in the battle against it. 他积极投身于抗击“非典”的战斗中。
against 与......相对抗
take part in... 参加......；加入到某种活动中
take an active part in... 积极参加......，如：
You should take an active part in the sports meet in your school.你应该积极参加你们学校的运动会。
6. He cared for the patients. 他日夜关心着病人。
care for sb. 关心某人
7. It's my duty to save the patients. 救治病人是我的职责。
It's...to do... 做某事是......，在此句式中，“to do...”是真正的主语，而“it ”是形式主语，类似的句式有：It's dangerous to climb the tree. 爬树很危险。
8. Long time no see. 好久没见！
这是一句常用口语，在久别重逢的朋友之间，还可以说：
“Haven't seen you for a long time！”。
9. I tought myself on the Internet. 我在网上自学。
1） on the Internet 在网络上。介词on用来表示在网上、电视上、收音机里、电话里。如：
2） on the phone， on the radio ，on tv
3） teach oneself 自学，近义词组为： learn by oneself
10. How often does Mr Brown exercise? 布朗先生多长时间锻炼一次？
how often 对频率提问，回答用 once/twice/three times...a day/a week/...
exercise在这里为动词，意思是“锻炼，运动”。
