一、定义：
祈使句表达说话人对对方的叮嘱、劝告、希望、禁止、建议、请求或命令等。
二、祈使句的特征：
以动词原形开头，无时态和数的变化。Grammar三、祈使句的句型：
1. 动词原形构成的祈使句
通常省略主语 you，谓语动词用原形。否定句由 don’t 或 never 开头。祈使句的句首或句末有时加 please。2. let 构成的祈使句
由“Let + me/us/him/her + 动词原形”构成。这类祈使句往往用于请求允许（let us）或提出建议（let’s）。例如：
Let’s spend this weekend in the countryside.
Let him be here by ten o’clock.3. 无动词祈使句
在请求，命令和口号中，常用无动词祈使句，它实际上是省略了动词，从而使语句更简洁有力。例如：
Just a minute, please!
在一些指示牌上，常用“No + 动名词/名词”构成省略的否定祈使句。
例如：No smoking!一、我们已经学习的表推测的情态动词有：
must/can/could/may/might
二、表推测的三种句式：
1. 在肯定句中一般用must，can/could，may/might，程度逐渐减弱。
e.g. He must/may/might know the answer to this question.
e.g. You have worked all this week. You must be tired.2. 在否定句中用can’t/couldn’t (不可能)，may not/ might not(可能不)。
e.g. It can’t /couldn’t be the headmaster. He has gone to America.
e.g. He may not/might not know the scientist.
3. 在疑问句中，一般只使用can/could。
e.g. Could he have finished the task?
e.g. Can he be at home now?must, can, may表示“推测”
顺口溜：can 不肯，
may 不问，
must 肯定不否问。 can不肯，即：can?(could)?一般不用于肯定句；
may不问，即：may?(might) 一般不用于疑问句；must肯定不否问，即：must一般仅用于肯定句，不用于否定句和疑问句。 That ______ be harmful!

Earthquakes are very common in Japan. Many can cause a lot of damage. But now there are new ways of constructing buildings to make them safer and stronger during earthquakes. The Yokohama Landmark Tower is one of the tallest buildings in Japan. It is heavy and strong. It sits on rollers.
