onlineWatching

televisionSummaryStructurePhrasessummary向某人询问某事……的答案每周四至六次一点也不……上网至少每周三或四次做某事的最好方式例如和某人一起度过时光开始做某事asksb.aboutsth.theanswerstofourtosixtimesaweeknot…atallgoonlineatleastthreeorfourtimesaweekthebestwaytodosth.suchasspendtimewithsb.startdoingsth.Goodbye!1.Herearetheresults.here开头的倒装句：当here位于句首，且句子的谓语动词是be动词或come,go等时，句子的主语和谓语要颠倒位置，构成倒装。here位于句首，若句子的主语是代词，则句子不用倒装。E.g.Hereyouare.Languagepoints2.Wefoundthatonlyfifteenpercentofourstudentsexerciseeveryday.

percentn.“百分之……”没有复数形式基数词+percent+of...“百分之……的……”作主语时，谓语的数和of后的名词，代词保持一致。►Seventypercentoftheboyslikeplayingcomputergames.男生中70%喜欢玩电脑游戏。►Thirtypercentoftimepasses.百分之三十的时间过去了。3.Andtwentypercentdonotexerciseatall!

not…atall“一点也不”，not应和be动词、助动词或情态动词连用。

e.g.那个故事一点也没有趣。他们根本不喜欢那次度假。那位老人一点也不会用电脑。(翻译)Thestoryisn’tinterestingatall.Theydidn’tenjoythevacationatall.Theoldmancan’tusethecomputeratall.4.…butweweresurprisedthatninetypercentofthemusetheInterneteveryday.surprised的用法e.g.我们队这个消息感到很意外。我在这里见到你很意外。(翻译)Wearesurprisedatthenews.Iamverysurprisedtomeetyouhere.surprisedadj.惊奇的，意外的besurprisedat...

对感到惊讶，后面可以跟somebody,something,或doingsomethingbesurprisedtodosth.做某事感到惊讶besurprisedthat+从句5.Althoughmanystudentsliketowatchsports,gameshowsarethemostpopular.

although是连词，意为“虽然，即使，纵然”，引导让步状语从句，相当于though，大多数情况下两者可互换。注意：although引导的从句不能与but连用，有although就没有but（即althoughbut不同现）。Althoughitrained,theboysstillplayedoutside.=Itrained,buttheboysstillplayedoutside.尽管天下雨了，但男孩们仍在外面玩耍。Ex.Hedidn'tsaysorrytome.Hewaswrong.(合并为一句）

Hedidn'tsaysorrytome________hewaswrong.although6.…butwethinkthebestwaytorelaxisthroughexercise.

through介词，“以，凭借”e.g.他通过报纸上的一个广告找到这份工作。(翻译)Hefoundthejobthroughanadvertisementinthenewspaper.through还有“穿过”之意。表示“从……内部过”。e.g.昨天他们穿过了森林。(翻译)Theywentthroughtheforestyesterday.易错点：辨析through,acrossthrough通过；穿过表示动作是在某一空间内进行的，强调从内部穿过across横过；横穿表示动作是在某一物体的表面进行的，强调从一边到另一边mind此处用作名词，意为“头脑；心智”。

Heisninetyyearsold,buthismindissharp.

他虽然90岁了，但头脑很灵活。7.Itishealthyforthemindandthebody.拓展mind作动词，意为“介意；对（某事）烦恼”，

常用于否定句，疑问句或条件句中。

其后跟名词，代词或动词-ing形式做

宾语。Idon’tmindthecold.Shedoesn’tminditatall.Doyoumindgivingmeaglassofwater?8.Exercise

suchasplayingsportsisfun,andyoucanspendtimewithyourfriendsandfamilyasyouplaytogether.►Iknowfourlanguages,suchas,EnglishandChinese.我了解四种语言，例如英语、汉语。►Shelikesanimalssuchasrabbitsandbirds.她喜欢像兔子、小鸟这样的小动物。（1）suchas用来举例，意为“例如；诸如此类的；像······那样的”，结构常为：名词+suchas+例子。注意：其后面不可列举出所有的事物。温馨提示：suchas可与like通用，所举例子只能为单词和短语，但forexam
