Tilly’s mother and the hotel workers acted quickly. They cleared people from the beach just minutes before a huge wave reached the land. Luckily, no one died.

一、情态动词must，can，could表示推测
1.我们学习过情态动词can和could用于对现在或将来的推测，意为“会，可能”，往往用于否定句和疑问句。用于疑问句时，can比could表示的“可能性”要大；用于否定句时，cannot (can’t) 表示“不可能”。如：
You can’t be serious!你不是认真的吧！
Grammar
could则可用于肯定句、否定句和疑问句。
在以下例句中，can和could均表示可能：
He could be in pain.他可能很疼。
That could be harmful!那可能有害！
Can/Could this be true 这有可能是真的吗？
2.情态动词must也可以表示猜测，意为“一定，准是”，通常只用于肯定句。
如：
Betty，you must know!
贝蒂，你肯定知道！
3.表示有把握的推测时，肯定句用must (一定，准是)，
否定句用can’t (不可能，一定不)。
对现在情况的推测：must (can’t)+动词原形；
对现在正在进行的情况的推测：must (can’t)+be doing；
对过去情况的推测：must (can’t)+have done。
如：
You must be hungry after a long walk.
长途步行之后你一定饿了。
They must be waiting for us.Let’s hurry up.
他们一定在等我们。让我们快点走吧。
You must have left your bag in the theatre.
你准是把你的包丢在剧院了。
You can’t be hungry, you have just had your dinner.
你现在不可能觉得饿，你刚吃过饭。
He wears glasses all the time, his eyesight can’t be getting better.
他一直戴着眼镜，他的视力不可能在好转。
4.表示把握不大的推测即可能性时，用can和may，常译为“也许，可能”。
may用于肯定句与否定句，一般不用于疑问句。
can常用于疑问句，一般不用于肯定句。
如：
The news may or may not be true.
这消息也许是真的，也许不是真的。
At the moment she may be playing with her classmates.
此刻她可能正在和同学们玩耍。
Anna might not have seen Tom yesterday.
安娜昨天可能没有看见汤姆。
Where can Wei Fang be
魏芳会在哪里呢？
二、祈使句
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。祈使句一般以动词原形开头，无时态和数的变化。常见的句型如下：
1.动词原形构成的祈使句
此类祈使句暗含的主语是you，但通常省略。
否定句往往由do not (don’t)或never开头。祈使句的句首或句末有时加please，还可以加上称呼语，用逗号与句子主体隔开。如：
Don’t waste your time! 别浪费时间了！
Never be late again! 再也不要迟到了！
Please be quiet，boys! 男孩们，请安静！
Make sure he’s warm.确保他不受凉。
2. let’s构成的祈使句
这类祈使句往往用于提出建议。
如：
Let’s spend this weekend in the countryside.
咱们到乡下度过周末吧。
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。如：
Just a minute，please! 请稍等！
This way，please! 请这边走！
