Presentatin
What grammar rule can yu ntice?
情态动词（Mdal Verbs）can, may, might, must…
Read the sentences frm the reading passage and summarise the grammar rules.
(a)Well, crayns may carry viruses and spread diseases.(b)It can be bring t wait fr X-rays and treatments.(c) There must be smething fr me t d.
What can yu find?
may表示可能性（可能，也许）
can表示可能性（有时会…）或能力（能够）
must表示肯定的推测（一定，肯定）
1.当我们想表达可能发生某事以及某人可能做某事时，可以用may/might表示。
例如:Bring a map because yu may want t travel arund.带张地图，因为你可能想四处转转。There may be a few shwers, s bring an umbrella with yu.可能会有阵雨，所以随身带把伞吧。
2.might与may没有太大的区别，形式上might是may的过去式，但在表示现在或将来的可能情况时，might表示的可能性比may表示的可能性要小一些。
例如:Take yur swimming clthes because yu might want t g swimming in the sea.带上游泳衣吧，说不定你想到海里游泳呢。
3.情态动词can和culd除了表示"能够，可以"等意义之外，还可以表示对现在或将来的推测，意为“会，可能。但can表示推测时，往往用于否定句和疑问句。用于疑问句时，can比culd表示的可能性要大;用于否定句时cannt(can't)表示“不可能。”
例如:Yu can't be serius! 你不是认真的吧!
4.culd则可用于肯定句、否定句和疑问句。在以下例句中，can和culd均表示可能:
例如:He culd be in pain.他可能很疼。That culd be harmful! 那可能有害!Can/culd this be true?这有可能是真的吗?
5.情态动词must也可以表示猜测，意为“一定，肯定”通常只用于肯定句。
例如:Betty, yu must knw! Betty，你肯定知道!
小总结（推测语气强弱）must (肯定) > may (可能) > can't (不可能)
请仔细对比下面一组句子:-Wh sent the present? Can it be yur brther? 是谁送来的礼物啊?会是你哥哥吗?(询问可能性)-It must be yur brther. I saw him in yur rm just nw. 肯定是你哥哥，我刚才看见他在你的房间里。(语气强烈，表示非常肯定)-It can't be my brther. He is still in France.不可能是我哥哥，他还在法国呢。(表示不可能)
