SectionA考点一Don’tarrivelateforclass.(1)该句是祈使句的否定形式，其结构为＂Don’t+动词原形+其他.”。Don’tlethimsithere.不要让他坐在这里。(2)arrivelatefor与belatefor同义，都表示“迟到”。arrivelatefor侧重动作，belatefor侧重状态。(3)arrive不及物动词，意为“到达”，后常接介词in或at，in后接大地方，at后接小地方。arrive后若是here，there，home等地点副词，则不需要用介词。getto也表示“到达”，后接地点名词，若接here，there，home等地点副词，则省略to。reach及物动词，意为”到达”，后常接地点名词。arrive，getto与reach有时可进行同义句转换。Theymustreach/getto/arriveatthevillageat8:00today.Iarrivehomeat4:00intheafternoon.Wegettoschoolat8:00everymorning.Tomalwaysreacheshisofficeontime.考点二Youmustbeontime.辨折:ontime与intimeontime准时，按时，指按规定的时间或指定的时间做某事。intime及时，指不迟到或在规定时间之前或接近所定的时间做某事。Theambulancearrivesintime.考点三Thisisveryimportant.important作形容词，意为“重要的”。常用句型为It’simportantforsb.todosth.importance作名词，意为“重要性”。ItisimportantforustolearnEnglishwell.Wemustknowtheimportanceofstudy.考点四Canwebringmusicplayerstoschool?bring作及物动词，意为“带来;取来”。常用结构bringsth.to.sb.意为“把某物/某人带到……”。Whydon’tyoubringyourcameratotheparty?辨析bring,take,getbring带来，取来，指从别处带到说话者所在的地方来。take带走，拿走，指从说话者所在的地方带到远处去。常与介词to连用。方向上与bring正好相反。get去取，指从说话者处去别处取到某物后再返回到说话者处，即一个来回。Pleasebringyourbookhere.Mycoatisinthenextroom.Canyougetitforme?考点五Oh,andwealsohavetobequietinthelibrary.辨析haveto/must两者都意为“必须”，后接动词原形，但用法不同。haveto必须，不得不，表示客观上需要，有人称，数，时态的变化。don’t/doesn’thaveto表示“不必”。must必须，一定，表示说话人主观上看法。mustn’t表示“禁止”。Youdon’thavetotellhimaboutit.祈使句1.定义用来表达命令、请求、劝告、警告、禁止等的句子叫作祈使句。祈使句通常省略主语you。例如:Bequiet,please.请安静。Pleasehaveaseat.请坐。2.句式结构(1)Do型:动词原形+宾语+其他。例如:Gothisway,please.请这边走。(2)Be型:Be+表语+其他。例如:Beagoodkid!做个好孩子!(3)Let型:Let+宾语+动词原形+其他。例如:Letmehelpyou.让我来帮你。注意:祈使句的否定形式一般是在动词原形前加don’t构成,有时也可直接用no开头表示禁止。例如:Don’tbelateforschool!上学不要迟到!Nosmoking!禁止吸烟!haveto与must的用法haveto和must均可表示“必须”。must更加强调说话者的主观意愿;而haveto强调客观的必要性,意为“不得不”。两者的否定式含义大不相同。mustn’t表示“不准;禁止”,而don’thaveto表示“不必”。例如:Imustgonow,orI’llbelate.我现在必须走了,不然我就会迟到了。Shehastohelphermotherlookafterhersister.她不得不帮着她妈妈照顾妹妹。Youmustn’tswimintheriver.你不准在河里游泳。Youdon’thavetodoitnow.你现在不必做这件事。注意:以must开头的一般疑问句,其肯定回答用must,否定回答用needn’t或don’thaveto。例如:—MustIfinishtheworknow?我现在必须完成这项工作吗?—Yes,youmust./No,youdon’thaveto.是的,你必须完成。/不,你不必现在完成。【跟踪训练】一、根据句意，用所给词的适当形式填空1.Do(do)theworkrightnow,Jim.
