begoodat,begoodfor,begoodto(1)begoodat表示“擅长……,在……方面做得好”,后接名词/代词/动名词,相当于dowellin。Sheisgoodatdancing.=Shedoeswellindancing.她擅长跳舞。(2)begoodfor对……有益(有用),后接表示人或事物的名词。Readingisgoodforyou.读书对你有好处。(3)begoodto对……好(和善、慈爱),后一般接表示人或人格化的名词,good相当于friendly。Heisverygoodtohisneighbors.他对他的邻居们很好。healthy:unhealthy:

本句是特殊疑问句,howmany后要接可数名词复数,再加一般疑问句。而howmuch后要接不可数名词,再加一般疑问句。Howmanybananasarethereinthebasket?这个篮子里有多少香蕉?Howmuchwaterdoyouneed?你需要多少水?StudentAisthereporter.StudentBisTinaorBill.Askandanswerquestions.Thenchangeroles.A:Howoftendoyouexercise?B:Iexerciseeveryday.A:Andhowoftendoyou…?Ranktheseactivitiesaccordingtohowoftenyouthinkyourclassmatesdothem(1=mostoften,6=leastoften).watchTV gotothemoviesplaycomputergames exerciseorplaysportsusetheInternetgocampinginthecountryReadthearticlesfastandfindthegeneralideaof2b.Thegeneralideaofthearticlesisabout

3.mindn.头脑,心智。Hehasaverysharpmind.他的头脑很敏锐。【拓展】

mindv.介意,当心,关心。mind后用动名词或名词作宾语,而不用不定式。Do/Wouldyoumind(one’s)doing…?用来客气地提出请求,或者用来提出询问、征求对方意见。Doyoumindclosingthiswindow?你介意关上这扇窗户吗?【固定搭配】

toone’ssurprise,insurprise,besurprisedat(1)toone’ssurprise是“令人惊奇的是……”,surprise是名词,one’s指形容词性物主代词或所有格,toone’ssurprise相当于“主语+be+surprised”,surprised是形容词。Tohissurprisehefoundthegirlwasblind.=Hewassurprisedtofindthegirlwasblind.令他惊奇的是,他发现这个女孩是个盲人。(2)insurprise是“惊奇地”,是副词性短语,用来修饰动词,一般放在所修饰的动词后面。Thetwogirlslookedateachotherinsurprise.那两个女孩惊奇地相互看着。(3)besurprisedat是“对……感到惊奇”,表示主语(一般是人)对某事或某物惊奇,surprised可以被very,too等修饰,作表语或定语。Weareverysurprisedatthenews.听到这个消息我们很诧异。2.Theanswerstoourquestionsaboutwatchingtelevisionwerealsointeresting.此句的基本意思是Theanswerswerealsointeresting.主语Theanswers为复数,故谓语动词使用were。【注意】本句中answer和question两个名词后的介词搭配。表示“……的答案”时,answer后要用介词to,这是一种固定搭配。There’snoeasyanswertothisproblem.这个问题没有简单的答案。Doyouknowtheanswertoquestionnumbertwo?你知道第二个问题的答案吗?3.ItisgoodtorelaxbyusingtheInternetorwatchinggameshows…◆Itis/was+adj.(forsb.)+todosth.对某人来说去做某事是……的。ItiseasyformetolearnEnglishwell.学好英语对我来说很容易。◆by+v.-ing构成方式状语,表示“通过某种方式、手段做某事”,by后接名词、代词、动名词形式。Shemademoneybywriting.她靠写作挣钱。Hesucceededbyworkinghard.他由于工作努力而获得了成功。Exercises:theend-of-classtestⅠ.根据汉语提示完成句子1.Twenty
