【学习目标】

三掌握情态动词：must / may / can / might / could 表推测的用法。

【学习重难点】1 belong to 的用法。

2 情态动词：must / may / can / might / could 表推测的【学习过程】
一课前复习下列句型：用whose 询问物体所有者，用be 和所有格及名词性物主代词和形容词性物主代词进行回答：
A,这是谁的书？_____ ______ is this? 或：_____ is this book?
B,这是王平的书。

This is __________ book. = This book is _____________
C,这是他的/我的书。

This is ____/ _____ book.= This book is ____/ _____.
二重点导学：
1.belong to 的用法：重点词组，意为：“某物属于某人或某人属于某个组织或团体”后接宾格。

如：这是我的书。

This book belongs to me.=This book is _____= This is __ book .
我是这个游泳俱乐部的成员。

I _____ _____ the swimming club.
注：belong to 没有被动语态和进行时态。

误：This book is belonged to me. 或：This book is belonging to me .
2.在英语中，表示对某件事物的确定程度即表示推测的时候，我们通常会用到以下情态动词: must, might, could, may,can’t, couldn’t.确信程度大小：must > may > might
肯定和否定的推测：must（肯定），can’t，couldn’t (否定）
（1）情态动词must, might, could, can’t 后接动词原形, 可以表示对现在的情况的推测.
It can’t (不可能)…
It might/could (有可能) …+ be (cold/happy/ sb’s)
It must (肯定) …
如：This book must be Tom`s, his name is on it.
Where is my book? It may be in your desk.(无根据但有可能)
（2）can 只用于否定句和疑问句。

如：（有人敲门）完成下列对话：
A：_____ it be Tom? 可能是汤姆吗？
B：No, it ____ be Tom, he has gone to America yesterday.不可能是汤姆，他昨天去美国了。

Can`t 表示推测的意义与must 刚好是反义词。
