areful!(=Lookout!=Takecare!)小心/當心!③Let’s+動詞原形...Let’smakeabananamilkshake.咱們一起制作香蕉奶昔吧。(2)否定的祈使句Don’t+動詞原形...Don’tpourthewateronthefloor.別把水潑在地板上。Don’tbecareless.別粗心。Don’tletthemplaywithfire.別讓他們玩火。Step9SummaryInthisperiod，wehavelearned：1.Newwords：shake，blender，peel，pour，yogurt，honey，watermelon，spoon2.Phrases：milkshake，turnon3.Sentences：Howmany...?Howmuch...?當堂達標(見導學案“當堂達標”)答案與解析：Ⅰ.1.Howmany對可數(shù)名詞的數(shù)量進行提問要用howmany。2.Howmuch，does，add對不可數(shù)名詞的數(shù)量進行提問要用howmuch；謂語動詞是第三人稱單數(shù)時，變疑問句應借助于助動詞does，謂語動詞變?yōu)樵巍?.Don’tpour祈使句的否定形式是在謂語動詞前直接加Don’t。4.Cutup祈使句常省略主語you，謂語動詞用原形。5.isn’tany含有be動詞的句子在變?yōu)榉穸ň鋾r，在be動詞之后直接加not；some主要用于肯定句中，否定句中應用an
