B：go and open the door.

I’ll ask some groups to show their jobs, and show my opinions for their performance such as “quite good! Well done! So excellent” and so on.

Step 5.Draw a conclusion and consolidation

a) Then ask ss to observe the sentences again. I’ll help them to draw a conclusion of the forms of imperative sentences. That is,

肯定结构: (Positive forms)

• 1. Do型(即:动词原形(+宾语)+其它成分)。

• e.g:Please have a seat here.=Have a seat here, please.

•有的祈使句在意思明确的情况下,动词可省略。如:This way, please. = Go this way, please.

• 2. Be型(即:Be + 表语(名词或形容词)+其它成分)。

• e.g Be a good boy!

• 3. Let型(即:Let + 宾语+ 动词原形+ 其它成分)。

• e.g Let me help you.

否定结构: (Negative forms)

• 1. Do型和Be型的否定式都是在句首加don’t构成。

e.g, Don't forget me!

•Don't be late for school!

• 2. Let型的否定式有两种:

•①“Don‘t + let + 宾语+ 动词原形+ 其它成分”

•②“Let + 宾语+ not + 动词原形+ 其它成分”。

• e.g Don’t let him go. / Let him not go.。

• 3. 有些可用no开头,用来表示禁止性的祈使句。

•No + n / doing + 其他成分

• e.g No smoking! No fishing!
