重点难点提示
1. first aid 急救
　　指医生未来之前对伤者所采取的急救措拖与处理。
　　其中的aid一词既可作动词也可作名词用，作“帮助”、“援助”、“促使”解。例如：
　　With the aid of the computer, he worked out the problem.　借助于计算机，他解决了这个难题。
　　They are determined to aid him in his scientific research.　他们决定对于他的科学研究给予援助。
　　She came quickly to his aid.　她急忙来帮助他。(=She came quickly to help him.)
　　在以上的句子中，aid均可被help替换，因为这二个词都有帮助的意思。help含义较广，在日常生活中用的较多，而aid是比较正式的用法，因此在日常生活中不多用。

2. Seconds count in an emergency, and knowing what to do can mean the difference between life and death.
　在紧急情况中分分秒秒都事关重要，知道怎么办就可能意味着生死攸关。
（1）count原义是数，这里转义为有价值，要紧，有严重性，又例：
　　Every penny counts.　每一分钱都有价值。
　　It's not how much you read but what you read that counts.
　　不是你读的量而是你读的内容重要。
　　The individual doesn't count much in the situation.
　　在这种情形下，个人没什么作用。
　　White lies don't count. 善意的谎言不要紧。
（2）count的其他用法：
　1） v. 数，看作
　　She asked the little boy to count three.　她要那个小男孩从1数到3。
　　He counted to five.　他数到五。
　　He counts it a duty to take care of the old couple.　他把照顾那老两口看作是自己的职责。
　2） n. 总数
　　I don't know the count yet.　我还不知道总数是多少。
　3）count on 依靠，指望
　　You can't always count on the help from others.　你不能总是靠别人的帮助。
　4）count up 把……加起来
　　You should count up those numbers first.　你首先应该把这些数字加起来。

3. We can do a lot of good by simply asking "Are you all right?"
　只要你问一句“你没事吧？”就可能帮大忙。
　　good可作名词意为好处：
　　She only thinks of others' good.　她只考虑他人的利益。
　　Perhaps it may do him good to have you here.　也许你在这儿时他有好处。
　　The walk has done his liver a lot of good.　散步对他的肝病很有好处。

4. We should check that the person can breathe.
　我们应该检查这个人能否呼吸。
　　这句中that也可用if或whether代之。意义不变，例如：
　　They checked that/if/whether every door had been locked.

5. If a person is bleeding, we should cover the wound with a clean piece of cloth and press on the wound to stop the bleeding.
　如果一个人在流血，我们应该用干净布盖住伤口，压迫伤口止血。
　　press为按，压等意义，例如：
　　She pressed down the lid.　她揿下盖子。
　　Press the button to start the machine.　按下开关起动机器。
　　My shoe presses my toe. / My toe presses against the shoe.　我的鞋挤脚。
　　He remained still for some time, with his lips pressed together.

6. However, after a few hours of study you will manage to know enough to save other people's lives.
　然而，经过几个小时的学习，你就能学会救命的方法。
　　这句中after短语与将来时连用，本意是after the study而不是after a few hours，试比较：
（1）After two days of discussion, they will reach the agreement.
　　(In two days, they will reach the agreement.)
（2）After three hours of hard work, he will succeed in clearing up the deserted garden.
　　(In three hours, he'll succeed in clearing up the deserted garden.)

7. ...but most of us will eventually find ourselves in a situation where we or someone else needs help.
　但是我们大多数结果会发现我们自己或别人处于需要帮助的情况。
（1）句中eventually意为结果、最后等等。
　　It was a long journey, but we eventually arrived.
　　The house will have to be repainted eventually.
（2）句中needs是遵从就近原则。类似的有：
　　There is a table and six chairs in the dining room.
　　Either he or I am mad.
　　Not only students but also the teacher is forbidden to smoke in the classroom.

8. Here is some advice for dealing with common injuries...

　　How shall we deal with the situation?　我们怎样来处理这个局面呢？
