11、感嘆號(hào)來(lái)表示結(jié)束。祈使句的肯定句：行為動(dòng)詞原形+其他 Be動(dòng)詞+adj let+sb+動(dòng)原.Eg:Go and wash your hands._。命令 Be quiet, please.= Please be quiet._。請(qǐng)求 Be kind to our sister._。勸告 Watch your steps._。警告祈使句的否定通常使用“Don't ”，Don't+動(dòng)詞原形（行為動(dòng)詞/be動(dòng)詞）+其他Eg:Don't touch, please.請(qǐng)不要用手觸摸。不要開(kāi)門(mén)_ Don't be silly.別傻了。不要太累。_以L(fǎng)et開(kāi)頭的祈使句，否定形

12、式是在賓語(yǔ)后加not,Eg:Lets not do that again.我們別再那樣做了?；蛘咧苯觧o +Ving Eg:不準(zhǔn)抽煙._祈使句有時(shí)也把主語(yǔ)“You”表達(dá)出來(lái)，使對(duì)方聽(tīng)起來(lái)覺(jué)得柔和些，例如：Eg:You go and tell him, Chris.克立斯你去告訴他。隨堂練習(xí)一、單詞變化（10分）1.rule(復(fù)數(shù))_ 2.outside(反義詞) _ 3.wash(單三)_ 4.get to (同義詞)_ 5. late(反義詞)_ 6.loud (副詞)_ 7.could (原形)_ 9.piano(復(fù)數(shù)) _ 10.snow (形容詞) _二單詞填空（10分） 1.We h
