Language practice
一、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。例如：
Grammar
Have a nice day! 祝你度过美好的一天！
Don’t waste your time! 别浪费时间了！
Never be late again! 再也不要迟到了！
Come this way, please. 请走这边。
Please be quiet, boys! 男孩们，请安静！
Make sure he’s warm. 确保他不受凉。
Don’t use the lift. 不要使用电梯。
2. let’s 构成的祈使句
这类祈使句往往用于提出建议。例如：
Let’s spend this weekend in the countryside.
这周咱们到乡下度周末吧。
Let’s take a taxi, shall we 我们坐出租车好吗？
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! 请稍等！
This way, please! 请这边走！
二、情态动词 must/can/could 表示推测
我们学习过情态动词 can 和 could 表示“能够，可以”等意义的用法。can 和 could 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 could 表示的“可能性”要大；用于否定句时，cannot（can’t）表示“不可能”。例如：
You can’t be serious! 你不是认真的吧！
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
情态动词 must 也可以表示猜测，意思为“一定，准是”，通常只用于肯定句。如课文中的例子：
Betty, you must know! 贝蒂，你肯定知道！
请仔细对比下列一组句子：
Who sent the present Can it be your brother
是谁送来的礼物啊？会是你哥哥吗？(询问可能性)
It must be your brother. I saw him in your room just now.
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 brother. He is still in France.
不可能是我哥哥，他还在法国呢。（表示不可能）
It is dangerous. You _______ keep out!
These stairs are not safe. You _______ use them.
The rocks are falling down. You ______ get hit.
The river is too deep. You ________ swim in it.
