04知识点1：祈使句的用法祈使句是用来表示请求、命令、希望、建议、劝告等的句子。（祈使句最常用来表示命令，因此也常被称为命令句。）特点：祈使句一般没有主语，因为主语you通常都被省略了。例句：Listentome!听我讲！Cleantheblackboard,please.请擦黑板。【肯定祈使句】1.结构：(1)动词原形+其他

例如：Openthedoor.开门(2)Be+形容词/名词

例如:Bequiet.安静。(3)Let+宾语+动词原形+其他例如：Let’scleanthechairs.让我们来擦椅子。知识点1：祈使句的用法2.用客气的语气表示祈使句时，可以在句首或句末加上please。*如果在句末加please，那再please前一定要用逗号隔开。例如：Pleaseclosethewindow./Closethewindow,please.请关窗。3.注意：祈使句中如果有称呼或者姓名，一定要用“,”隔开，放在句首或者句末。例如：Mike,comein.麦克，进来。Comein,Mike.进来，麦克。【否定祈使句】祈使句的否定形式，在动词前加don’t。例如：Cleanyourdesk,Bobby.（改为否定句）→Don’tcleanyourdesk,Bobby.【祈使句的回答】回答时可以用“Allright./Ok./Yes./Sure.”等。Sweepthefloor,please.Let’scleanourclassroom.Putthesebooksinyourschoolbag.Don’tputDon’tclosethedoor知识点2：let的用法Let’s…是祈使句的一种，表示建议做某事，意为“让我们……/咱们……”，用法如下：(1)Let+人称代词宾格→Letus=let’s,Letme,Letthem…(2)Let+动词原形→Let’shavealook.mesweepusclean知识点3：can的用法表达某人会做某事的句型：主语+can+动词原形+其他。情态动词can的用法：(1)can+动词原形(2)否定形式cannot=can’t（否定句改写直接在can后面加not）(3)一般疑问句把can提到句首，肯定回答：Yes,主语+can.否定回答：No,主语+can’t.例句：Wecankeeptheclassroomclean.我们可以保持教室干净。否定句：Wecan’tkeeptheclassroomclean.一般疑问句：Canyoukeeptheclassroomclean?肯否回答：Yes,wecan./No,wecan’t.CAArunjumpCancleancan’tclean知识点4：人称代词人称代词是指直接指代人或者事物的代词。在英语和中文中都有三种人称代词，即第一人称（我/我们）、第二人称（你/你们）、第三人称（他/她/它；他们/她们/它们）。知识点4：人称代词(1)主格作主语，一般放句首。例如：Wecancleanourclassroom.我们可以打扫我们的教室。(2)宾格放在be动词或介词后面。例如：Thisisme.这是我。Thattoycarisforyou.那个玩具小汽车是给你的。(3)形容词性物主代词，翻译带“的”，表示“属于某人”。例如：Icancleanmydeskandchair.我会打扫我的桌椅。Ourclassroomiscleannow.我们的教室现在是干净的。CCAHeSheItIYouWethemmeouryourPractice
