2) 表示允许、许可, “可以”、“能”
(在这一课中新学的词义)
Can the students run in the hallways
学生们可以在走廊上跑吗？
We can eat outside.
我们可以在外面吃东西。
注意: 和大部分情态动词一样, can在否定句中, 直接在can后加上not, 在疑问句中, 把can放到主语前面, 并且没有人称和数的变化。
肯定祈使句
Sit down.
Come in.
Eat at home.
否定祈使句
Don’t sit down.
Don’t come in.
Don’t eat at home.
祈使句是用来表示请求、命令、叮嘱、号召或者劝告等的句子, 这类句子的主语常是第二人称you,也就是听话者,因而you常省去了。祈使句的开头是动词原形。
如:
Look out! 小心！
Wait here for me! 在这等我！ Be sure to come here on time! 务必准时来到这里！
Listen to music outside.
Don’t listen to music outside.
Do your homework at school.
Don’t do your homework at school. Don’t look out of the window.
不要向窗外看。
祈使句的否定形式多以do not (常缩写成don’t) 开头, 再加上动词原形。
祈使句表示请求、命令、劝说、号召、
警告等。表示委婉的祈使语气，可在句首或句末加上please，若在句末加please，之前要用逗号隔开。祈使句有肯定祈使句与否定祈使句两种。
祈使句的常见句型结构
1. 肯定祈使句的常见句型结构：
① Do型：动词原形+宾语+其他. 如：
Open the door, please.
② Be型：Be+表语. 如：Be a good boy!
③ Let型：Let+宾语+动词原形+其他.
(或：Let’s+动词原形+其他.) 如：
Let me help you.
又如：Let’s play tennis.
2. 否定祈使句的常见句型结构：
① Do型和Be型的否定式：Don’t+动词
原形 / be+其他. 如：Don’t forget me.
又如：Don’t be late.
② Let型的否定式：Don’t+let+宾语+动词原形+其他. (或：Let’s+not+动词原形+其他.) 如：Don’t let him go back. 又如：Let’s not go swimming.
③ 警示语：No+名词 / 动词-ing形式. 如：
