B．excitedenough C．tooexcited

D．enoughexcited句意：哈利昨晚兴奋得睡不着，因为他在学校足球赛中得了一等奖。nough修饰形容词要后置，排除D；根据“Harrywas...tosleeplastnightbecausehewonfirstprizeintheschoolfootballmatch.”可知，因为他在学校足球赛中得了一等奖，所以应是兴奋得睡不着。too...todo“太……而不能做某事”，固定短语。故选C。Grammar5语法3.Thesedayslotsofpeopleareworking________toget_______fortheirliving.A．hardlyenough;enoughmoney B．enoughhardly;moneyenoughC．enoughhard;moneyenough D．hardenough;enoughmoney句意：现在很多人都在努力工作，以获得足够的钱来维持生计。hard努力地；hardly几乎不。第一空应用副词修饰谓语结构areworking，即“努力工作”。enough修饰形容词、副词或动词时应放在被修饰词的后面，且enough修饰名词时放在所修饰的名词前。故选D。Grammar5语法4.Thetentis________forafamilyofthree________.A．bigenough;tolivein B．enoughbig;toliveinitC．bigenough;tolive D．enoughbig;livein句意：这个帐篷足够大能让一个三口之家居住。根据“Thetentis…forafamilyofthree…”可知，此处是固定用法：形容词/副词+enoughforsb.todosth.，动词不定式与主语thetent之间构成逻辑上的动宾关系，live为不及物动词，其后应该加上相应的介词，“住在帐篷里”要用livein。故选A。Grammar5语法5.Kitty,thesebooksare_____heavyforyou____carry.Letmehelpyou.A．so...that B．too...to

C．such...thatD.enough...to句意：基蒂，这些书对你来说太重了，你拿不动。我来帮你。考查非谓语动词。so…that+从句，如此……以致于……；too…to+动词原形，太……而不能；such…that+从句，如此……以致于……；enough...to+动词原形，足够……做某事。根据“carry”是动词原形可知此处用too…to结构，且指“太重了拿不动”。故选B。Grammar5语法6.Westudentsaretoobusy_______todoany_______afterclass.A．todoexercise;exercise B．doingexercises;exerciseC．todoexercises;exercises D．doingexercise;exercises句意：我们学生课下太忙于做练习而不能进行体育锻炼。考查非谓语动词。bebusydoingsth.忙于做某事；tooadj.todosth.太……而不能做某事。结合常识可知忙于做练习而不能锻炼，exercise作“练习”讲是可数名词，作“锻炼”讲是不可数名词。故选B。课堂小结PART.04Grammar5语法1.掌握enoughto与too...to的用法2.掌握enoughto与too...to的转化课后作业：语法练习（附课后作业word文档）课后作业讲解PART.05Grammar5语法1.—Theboxis________formetocarry.Whocanhelpme?—IthinkSimonis________todoit.A．tooheavy;toostrongB．soheavy;strongenoughC．tooheavy;strongenoughD．soheavy;toostrong2.—Amy,Iwenttotheconcertlastnight.Howbigthehallis!—Yes,itis_________morethanonethousandpeople.A．verybigtoholdB．bigenoughtoholdC．enoughbigtoholdD．toobigtoholdGrammar5语法3.—Mum’sbirthdayiscoming.Whatwouldyoubuyforher?—I’mnotsure.Anyway,Iwillfind________.A．enoughbeautifulsomething B．somethingbeautifulenoughC．somethingenoughbeautiful D．beautifulsomethingenough4.—WhynotlistentoBBCnewstoimproveyourlisteningskills?—It’s________difficultforme________follow.A．too;to B．so;that C．such;that D．so;tooGrammar5语法5.Thelittleboywas_____excited_____sayawordwhenheknewtheresultofthefinalexam.A．too;to B．so;that C．so;as D．such;that6.—DoyouthinkDavidis_____tobethehostofthecharityshow?—I’mafraidnot.Heis_____tobethehost.A．toobrave;notbraveenoughB．braveenough;toobraveC．braveenough;tooshyD．toobrave;shyenoughGrammar5语法7.—Don’tpunish(惩罚)him.He’sonlytwoyearsold.—Akidisnever________learngoodmanners.A．toooldto B．tooyoungto C．oldenoughto D．youngenoughto8.Avatarissuchapopularmoviethatitcatchesmanypeople’sattention.(注意力).(同义句转换)ThemovieAvataris__________________catchmanypeople’sattention.popularenoughtoGrammar5语法9.Theyoungboywasverycle
