【思路点拨】
1. 定基调
本文要写一段对话，那么我们就来了解一下对话体语篇的结构特征。
◆必须遵循“轮流规则”，即在进行交谈时，轮流讲话，轮流发言。
◆对话是一个回合接着一个回合，一个话题接着一个话题，话语进程基本上是直线发展的。
◆语言符合口语特征，一些补白表达，如well, yeah, you know等的使用会使对话自然、流畅。
时态：一般现在时和一般过去时 人称：第一人称和第二人称

5. have a sore throat喉咙痛
6.get an X-ray 拍X光片
7. have a headache 头痛
8. have bad colds 患重感冒
【词汇用法】
happen
happen是动词，意思是“发生”、“碰巧遇到”，常用来表达意外事件或偶然的结果。
happen是不及物动词，它的用法常见的有如下几种情况：
1)表示“某地(某时)发生了什么事”，常用“sth.+happen+地点/时间”这一结构来表达，此时主语应是事情。
例如：the story happened in 2003. 这个故事发生在2003年。
An accident happened in that street.那条街上发生了一起事故。
表示“某人出了某事(常指不好的事)”，要用“sth.+happen+to sb.”这一结构来表达。例如：a car accident happened to her this morning.今天上午她发生了交通事故。
What happened to you 你怎么啦
表示“某人碰巧做某事”，要用“sb.+happen+to do sth.”这一结构来表达。
例如：I happened to meet a friend of mine in the street yesterday.
昨天我碰巧在街上遇到了我的一个朋友。
happen表示“碰巧或恰巧发生某事”时，还可用“it happens/happened that...”这一结构来表达。
例如：It happened that Brian and Peter were at home that day.
碰巧那天布莱恩和彼得在家了。
It happened that he had to take part in a meeting that afternoon.
碰巧那天下午他不得不参加一个会议。
注：that从句中的主语是人时，此种结构可以与“sb.+happen+to do sth.”结构互换。例如：It happened that Brian and peter were at home that day.
=Brian and Peter happened to be at home that day.
2. hurt
用作及物动词
使受伤 No one was seriously hurt in the traffic accident.在这次交通事故中没有人受重伤。
使疼痛 The tight shoe hurt my foot、这只鞋太紧,把我的脚挤疼了。

用作名词
(精神上的)创伤[(+to)] It was a real hurt to her vanity. 这对她的虚荣心真是一个打击。
伤;痛 The massage made the hurt go away、按摩使疼痛消失了。
用作形容词，表示(心灵等)受到伤害的
There was a hurt look in her eyes、她的眼睛流露出一种委屈的神色。
be hurt后可接动词不定式或that从句。
She was hurt to think of his being left alone. 想到他一个人留在那儿她就难受。
【重点句型】
I hurt myself playing soccer.我踢足球时受伤了.
Jack hurt his back playing volleyball. 杰克打排球时伤了背.
上述两个句子playing soccer\volleyball为现在分词短语，作伴随状语，表示hurt myself\his back这一动作是在play soccer\volleyball期间发生的。可在前面加上when或while,相当于时间状语从句when/while l was playing soccer\volleyball.

Early to bed, early to rise, makes a man healthy, wealthy and wise.
This is an old English saying. Have you heard of it before I means that we must go to bed early and get up early in the morning. Then we shall be healthy. We shall also be wealthy and wise.
This is true. The body must have enough sleep to be healthy. Children of young age should have ten hours’ sleep every night. Children who don’t have enough sleep can’t do their work very well. They will not be wise and they may not become wealthy.
The body also needs exercise. Walking, running, jumping, swimming and playing games are all exercise. Exercise keeps the body strong.
Exercise also helps the blood (血液) to move around inside the body. This is very important. Our blood takes food to all parts of our body. The head also needs blood. Exercise helps us to think better!
( )26. If we get up early and go to bed early, we’ll _____.
