Giving instructins
Draw a cnclusin:
1.祈使句的概念祈使句( Imperative Sentence）表命令、請(qǐng)求、勸告、警告、禁止等。作用為：要求、請(qǐng)求或命令、勸告、叮囑、建議別人做或不做一件事。祈使句因?qū)ο螅粗髡Z(yǔ)）是第二人稱（yu），通常主語(yǔ)被省略。句末則使用感嘆號(hào)或句號(hào),讀降調(diào)。
2.祈使句結(jié)構(gòu):肯定形式：動(dòng)詞原形開(kāi)頭. 否定形式：Dn’t /D nt +動(dòng)詞原形.
表示請(qǐng)求、勸告的祈使句還常常在句首或句末加上please,?構(gòu)成句式： Please … …, please.?以使語(yǔ)氣更加緩和或客氣。
Please?have?a?rest. Have?a?rest, please.
D yu knw hw t make cards?
_______ ut pieces f card with a pair f scissrs._______ sme wrds r a sentence n each card._______ a picture abut the wrds r sentence n the ther side f the card._______ at the picture and ______ t say what is n the ther side.Please __________ (nt give) up. _______ trying and yu will find yu can remember things better.
What instructins can we see in public places?
Instructins at schl
Please _______________.
Please be __________ thers.
Please dn’t _______ fd.
Please dn’t ______ the rad when the light is _____.
clse the dr
Dn’t ___________ schl again.
Instructins abut traffic
Instructins in public places
2.Let型祈使句 Let?me?try. 讓我試試看。 Let’s?lk?at?the?map. 讓我們看看地圖?！?let’s是let?us的縮寫。Let’s型祈使句，其否定式也可用Let’s?nt … Let’s?nt?have?rest. 咱們別休息了。 Let’s?nt?sit?here!?我們不要坐在這兒！
注意：1.有些用N開(kāi)頭用來(lái)表示禁止性的祈使句 如： N smking!禁止吸煙 N phts!禁止拍照
祈使句,無(wú)主語(yǔ),只用動(dòng)詞原形就可以。表示請(qǐng)求或命令,加上please表客氣。如果變成否定句， Dn’t開(kāi)頭是規(guī)律。

Giving advice
The tne is strnger
當(dāng)我們給他人提建議時(shí)，可以用had better（’d better）和shuld，表示“最好”或“應(yīng)該”做某事， had better的語(yǔ)氣比shuld強(qiáng)一些。
注意：had better和shuld在使用時(shí)沒(méi)有人稱和數(shù)的變化， 后面都加動(dòng)詞原形。
had better 的否定式是直接在后面加nt。
shuld 的否定式是shuld nt/shuldn’t。
The structures f shuld/had better:肯定形式：shuld + d sth. 否定形式：shuld nt +d sth. 肯定形式：had better +d sth.否定形式：had better nt +d sth.
