1. 祈使句
(1)祈使句定义: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;祈使句暗含的主语是you,但通常省略;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。
(2)祈使句常见的句型
①动词原形构成的祈使句(Do型和Be型),此类祈使句否定句式往往在句首加don't。
Have a nice day! 祝你度过美好的一天!
Close the door! 请关门!
Be quick! 快点!
Don't close the door! 请不要关门!
② Let型的祈使句
这类祈使句往往用于提出建议。否定句式在句首加don't或在宾语后加not.例如:
Let him go to the park. 让他去公园吧。
Don't let him go to the park. /Let him not go to the park. 别让他去公园。
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,使语句更简洁有力。
Just a minute, please! 请稍等!
This way, please! 请这边走!
2. 情态动词must, can, could 表示推测
Can 和 could 可以表示对现在或将来的推测,意为"会,可能"。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!
—Can it be our teacher? 那个人有可能是我们老师吗?
—No, it can't be our teacher. He is on a visit to the Great Wall.
不可能。咱们老师正在游览长城呢。
Could 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。
She could be at home. 他可能在家。
Can/could this be true? 这有可能是真的吗?
2. must 表示猜测,意为"一定,准是",语气强烈,通常只用于肯定句。例如:
Betty, you must know!
贝蒂,你肯定知道!
The light is on, so he must be at home now.
灯亮着,他现在肯定在家。
