so后面是跟形容词和副词；而such后面是跟名词。

suchthat与sothat都可以用来引导结果状语从句，意为“如此以致”。

suchthat的句型结构可分为以下三种：

such+a（n）（+adj.）+单数可数名词+that从句。

Sheissuchagoodteacherthatallofusloveandrespecther.Tabletennisissuchaninterestinggamethatpeopleallovertheworldplayit.such（+adj.）+复数可数名词+that从句。

如：

TheyaresuchinterestingbooksthatIwanttoreadthemoncemore/again.such（adj.）+不可数名词+that从句。

如：

ItwassuchbadweatherthatIhadtostayathome.,2）so是副词，与形容词或副词连用，其结构是：

so+adj.（adv.）+that从句。

HeransofastthatIcouldntcatchupwithhim.IamsosleepythatIcanhardlykeepmyeyesopen.,注意当名词前面有many，much，few，little等表示数量多少的限定词时，应该用so，而不能用such。

Thereweresomanypeopleinthestreetwatchingthefirethatfirefighterscouldnotgetclosetothebuilding.当单数名词前有形容词时，既可用so，也可用such，但不定冠词的位置却有所不同。

Thisissuchanimportantmeetingthatyoushouldattendit.（=Thisissoimportantameetingthatyoushouldattendit.）这是一次很重要的会议，你一定要参加。

5、Shewassoonoutofbreath,butshecontinuedtorun.outofbreathTomrantotheshoptogetsomesaltforhismother.Whenhereachedthere,hewasquiteoutofbreath.continuedtodosth.=continuedoingsth.接着做,1）catchupwithsb.追上,赶上（强调结果）2）gothrough（仔细地）搜查，在中搜寻，浏览，翻看（速度较快的看）Shewentthroughherbag,butshecouldntfindherkey.3）runstraightat向直冲过去,6.Whenshecaughtupwiththem,shesawthattheyhadsatdownandweregoingthroughthecontentsofthebag,sosheranstraightatthem.,7.Themengotsuchafrightthattheydroppedthebagandranaway.这两个人吓了一跳，result?

suchthat,need/wantdoingsth.需要被做，后面接的动名词有被动的含义。

=needtobedoneThecarneedswashing.mend是表示“修修补补，小修小补”，常用于修补打破、撕破的东西或衣物等。

repair也是表示“修理”，不过repair是指修理好损坏的、用旧的东西，或是出故障的机器Ourclavichordisbeingrepaired.我们家的击弦古钢琴正在修理。

Illmendtheshirt.我会补那件衬衫的。

总之，repair比mend正式，表示缝补的时候我们多用mend.,8、Thestrapneedsmending,saidMrs.Sterlinglater,buttheydidnotstealanything.,想起，想到冒风险追赶举行野餐在的边缘为所有（主物）占有（主人）上气不接下气,thinkoftaketheriskofrunafterhaveapicnicattheedgeofinonespossessionoutofbreath,赶上，追上翻看，搜查包里的东西向直冲过去逃走需要被做如此.以致,catchupwithgothroughthecontentsofthebagrunstraightatrunawayneeddoingsuchsothat,Summary,_mentriedto_Mrs.AnnSterlings_whileshewas_with_.Thementookthebagaftera_andran_thetrees.Mrs.AnnSterling_themandcaught_them.Themenhadsatdownandwere_the_ofthebag.Mrs.Sterlingran_atthem.Themengot_afright_theydroppedthebagand_.,Two,steal,handbag,havingapicnic,herchildren,struggle,through,ranafter,upwith,goingthrough,contents,straight,such,that,ranaway,【Keystructures】动名词1、动名词可以做主语、宾语、介词宾语等Washingthecarmademetired.（主语）Beforeleavingtheoffice,hegavemeabook.（宾语）Iamverykeenoncycling.（介宾）,2、动名词还可以用于“动词+介词”之后to后跟动名词的有（此时to为介词）lookforwardtodoingsth.期盼做某事Iamlookingforwardtoseeinghimtomorrow.beaccustomedtodoingsth.习惯于做某事Iamaccustomedtogettingupearly.我习惯早起.beusedtodoingsth.习惯做某事Iamusedtogettingupearly.我习惯早起.,preferdoingtodoing与相比更喜欢做Ipreferwalkingtodriving.devotetodoingsth.奉献给某事,devoteoneselftodoingsth.（全身心投入做某事）Mymotherdevotesherselftodoinghousework.objecttodoingsth.反对做某事Iobjecttoeatingout.我反对在外面吃饭.payattentiontodoingsth.,其他介词,get/betiredofdoingsth.对厌烦,作为系动词get可与be替换believein信任,信仰believein+sb.表示信任某人,信仰某人believein+doingsth.信仰.Ibeliveintakingiteasy.（takeiteasy轻松,放松,慢慢来）accusesb.ofdoingsth.因某事控告某人（accusevt.控告；指控）Thepoliceaccusedhimofstealing.警方控告他犯有盗窃罪.,beafraidofbegoodatdowellin等,3、在start，begin，continue等后面，既可以用不定式又可以用动名词，区别不大：

Ibegantolearn/learningEnglishtwoyearsago.,与表示心理状态的词连用：

但在有些情况，通常用todo.如：

物作主语：

sthbegins/begantodosth.,Itbeginstorain.,4、在hate、love，like，prefer等动词后，用不定式和动名词意义有所区别。

Heranquicklytocatchthelastbushome.Whenshecaughtupwiththem,shesawthattheyweregoingthroughthecontentsofthebag.run的本意是“跑”，后面加上不同的小品词可以表达“追赶，逃跑”等多种含义：

Shehasrunoffwithallhismoney.Themanranawaywithherbag.runafter,
