Guide Two Review and Summary
表推测的情态动词
情态动词must, can, may, could, might都可以表示推测。
◆must表示对现在的状态或现在发生的事情很有把握的推测， 意为“一定； 准是”，可能性为100%。
如：You have studied for a long time. You must be tired.
◆may, could, might这三个词表示的可能性较小， 意为“有可能； 也许”， 可能性占20%至80%。 如：
My friend has lost his watch. This may /might / could be his, but I’m not sure.
◆can’t 表示很有把握的否定推测， 意为“不可能”，可能性为0%。 如：
The blue motorbike can’t be your mother’s. Hers is yellow.
表推测情态动词的用法
一、根据被推测的时间，确定动词的形式。
“情态动词+do”形式：表示对现在或将来情况的推测。
2. “情态动词 + be + doing”形式：表示对此时此刻正在发生的事情的推测。
3. “情态动词+have done”形式：表示对过去情况的推测。
二、根据猜测语气的强弱，选择情态动词。
在肯定句中表推测，must语气最强， 表示“肯定，一定”；
could, may, might语气依次减弱，表示“可能， 也许”。
2. 在否定句中表推测，can’t, couldn’t语气最强，表示“不可能”; may/might not语气较弱，表示“可能不”；mustn’t 表示“禁止”，不用于否定推测。
1. It used to be very quiet.
used to do sth. 曾经，过去常常
（现在不做了）
be used to do sth. (=be used for doing sth.) 被用来做……
be used to doing sth. 习惯于做……
2. However, these days, something unusual is happening in our town.
构成：不定代词+形容词
（定语后置）
un- 表示否定
usual 通常的 unusual 不平常的
happy 快乐的 unhappy 不快乐的
lucky 幸运的 unlucky 不幸的
friendly 友好的 unfriendly 不友好的
easy 轻松的 uneasy 不安的
反义

早上，同学们发现Jack两眼通红。于是大家纷纷猜测Jack发生了什么事情，有的同学认为他昨天晚上一直在玩手机游戏，有的同学认为他昨晚做作业做到很晚，也有的同学认为……，而真正的原因是他感冒了，没有睡好。请以“What happened to Jack ”为题，写一篇短文。

最终结果
Jack’s eyes were red
played mobile games all night
did his homework very late
watched TV the whole night
caught a bad cold
This morning, we found that Jack’s eyes were red. What happened to him We guessed.
Some of the boys thought that he must have played mobile games all night, because he always spent a long time doing that. But some girls didn’t agree. They believed that he must have done his homework very late.
Others thought that he was watching TV the whole night, because there was an NBA game last night. But I didn’t agree with them. His parents were very strict with him, so he couldn’t have played games or watched TV.
Then, we asked him during the break, and he said he cought a bad cold. Poor Jack!
