二、语法知识清单

祈使句

1. 定义

用来表示请求、命令、建议、号召、警告等的句子。说话的对象大多为第二人称you，且常被省略。句末用感叹号或句号，读时用降调。为了表示客气，常用please一词。放在句首时，其后不加逗号；放在句末时，其前通常加逗号。

2. 构成：祈使句分为肯定祈使句和否定祈使句。

(1) 肯定祈使句的构成：

① Do型，即以行为动词原形开头。

② Be型，即以动词be开头。

③ Let型，即以let开头。

例如：Move quickly!

Stop talking!

Watch out!

Be quiet please!

Be quick/fast!

Let’s play basketball.

Let’s go out for fun.

(2) 否定祈使句的构成：

① Do型和Be型的否定式，在动词前加don’t或never，即“Don’t do/be sth.”或者“Never do/be sth.”。

② Let型的有两种否定形式：在let前加don’t，即“Don’t let sb. do sth.”或在let sb.后加not，即“Let sb. not do sth.”。

③其他类型：“No +v.-ing形式/名词”，用于警示人们不要做某事。

例如：Don’t come in.

Don’t be sad. You are so nice.

Jerry, never give up yourself.

Never be angry.

Don’t let them cry. = Let them not cry.

Let me not go there. = Don’t let me go there.

No talking/parking/smoking!

3. 答语

祈使句的动作通常是将来发生的动作，所以回答祈使句时，一般用will或won’t。

【注意】在回答具有否定意义的祈使句时，要注意形式一致和意义相反。即：yes与will；no与won’t要一致；yes意为“不”；no意为“是”。

例如：—Don’t go out. It’s raining hard. 不要出去了。天正下着大雨。

—Yes, I will. Lily is waiting for me. 不，我要去。莉莉在等我呢

—No, I won’t. I will stay at home. 好的，我不会去的。我待在家就好。

4. 其他用法: 祈使句和陈述句的连用

(1)祈使句+ and/ then + 陈述句，二者之间表示一种顺承关系。

例如：Study hard, and you can get good grades.

Be careful, and you will find it easy.

Act it now, and our world will be better.

Plant more tree, and the earth will be more beautiful.

(2)祈使句+ or +陈述句，二者之间表示一种否定条件。

例如：Move quickly, or you will miss the bus.

Study hard, or you will fail the exam again.

Remember these sentences, or you won’t pass the test.

Be polite to others, or they will be sad because of your words.

三、语篇知识清单

Dear Jill,

I'm now in Class 4 Grade 7. To make our class better in our school, we have some class rules. Let me tell you some of my class rules.

First, we can't arrive late for school. So we have to go to bed early and get up early. Second, we have to finish our homework on time. Third, we can't fight with our classmates. And last, we must clean our classroom every day and keep it clean.

Yours,

Lisa
