so…thatso…that【知识点解析】一、so...that的基本用法“so...that...”句型的意思是“如此/这么……以至于……”，常引导结果状语从句。“so...that...”句型及其转换也是中考的热点，现将其用法总结归纳如下：1.so...that...句型中的so是副词，常常用来修饰形容词或副词，常用句型为：主语+谓语+so+adj./adv.+that从句。例如：

so…that【知识点解析】Heissoyoungthatshecan’tlookafterherself.TheboyransofastthatIcouldn’tcatchhim.Hewassoangrythathecouldn’tsayaword.2.so+形容词+a(n)+单数名词+that从句。例如：Shemadesogoodamealthatweallatefartoomuch.ItwassogoodanexhibitionthatIwenttoseeitseveraltimes.Itwassofineadayyesterdaythatweallwentoutforapicnic.so…that【知识点解析】3.在“such...that...”句型中，such修饰名词，意思也是“如此……以至于……”但当名词前有many,much,(a)few,(a)little等词修饰时，句子中要用“so...that...”而不能用“such...that...”。例如：Hehassomuchmoneythathecanbuywhathewanted.ThereissolittlewaterintheglassthatIcan'tdrinkanymore.I’vehadsomanyfallsthatI’mblackandblueallover.Therewassomuchworktodothateverybodygotbored.Therewassolittlewaterinthejarthatitwasnotenoughforallofus.（注：当little的意思是“小”时，仍用such...that...）so…that【知识点解析】4.so与that也可连起来写，即变成：...sothat...(以便/为了……)，引导目的状语从句。例如：IgotupearlysothatIcouldcatchtheearlybus.Pleaseopenthewindowsothatwecanbreathefreshair.Youmustgonowsothatyouwon’tbelate.

so…that【知识点解析】5.以“so...that”引导的结果状语从句可以转换成不定式的简单句，即可转换为“...enoughto...”或“...too...to”句型，但这种转换必须符合下列条件：（1）当主句和从句的主语一致，且that从句是肯定句时，可用“enoughtodosth.”来转换。例如：Themanissostrongthathecanlifttheheavybox.→Themanisstrongenoughtolifttheheavybox.HewassocleverthathecanunderstandwhatIsaid.→HewascleverenoughtounderstandwhatIsaid.

so…that【知识点解析】（2）当主句和从句的主语不一致，且that从句是肯定句时，可以用“enoughforsb.todosth.”来替换，但须注意不定式的宾语要省略。例如：ThequestionissoeasythatIcanworkitout.→Thequestioniseasyenoughformetoworkout.Theboxissolightthathecancarryit.→Theboxislightenoughforhimtocarry.

so…that【知识点解析】（3）当主句和从句的主语一致，且that从句是否定句时，可以用“too...to”来替换。例如：Thegirlissoyoungthatshecan’tdressherself.→Thegirlistooyoungtodressherself.IwassotiredthatIcouldn’tgoonwiththework.→Iwastootiredtogoonwiththework.

so…that【知识点解析】（4）当主句和从句的主语不一致，且that从句是否定时，如果要用“too...to...”替换“so...that...”，则用介词for引出动词不定式的逻辑主语，可以用“too...forsb.todosth.”来替换，注意不定式的宾语要省略。Thebagissoheavythatshecan’tmoveit.Thebagistooheavyforhertomove.Itissohotthatwecan’tsleep.→Itistoohotforustosleep.

so…that【知识点解析】二、such…that的用法在such...that...句型中，such修饰名词，意思也是“如此……以至于……”。such…that…引导四种不同的句子结构：1.such+a(n)+形容词+单数名词+that从句。例如：Thisissuchagoodbookthatallofuslikeitverymuch.这是一本很好的书，我们大家都喜欢读一读。so…that【知识点解析】Itwassuchafinedaythatnobodywantedtostayathome.天气这么好，没有人愿意呆在家里不出去。ItwassuchaninterestingfilmthatIsawittwice.这是一部很有意思的电影，我看了两次。2.such+形容词+复数名词+that从句。例如：Hehadsuchlongarmsthathecouldalmosttouchhisknees.他的胳膊很长，几乎就能够到他的膝盖。Theyaresuchgoodstudentsthattheteacherlikesthem.他们都是很好的学生，老师喜欢他们。so…that【知识点解析】3.such+（形容词）+不可数名词+that从句，例如：Itwassuchfineweatheryesterdaythatwewentswimming.昨天天气很好，我们去游泳了。4.one(no,any,all,many,some,several,等)+such+可数名词+that从句。例如：TherearemanysuchgoodbooksthatIcan’tdecidewhichonetochoose.有这么多的好书，我无法决定选择哪一本。Hegaveusseveralsuchexamplesaboutthephrasethatweunderstooditprettywell.关于这个短语，他举了好几个这样的例句，我们终于完全弄懂了。so…that【知识点解析】三、sothat既可以引导目的状语从句又可以引导结果状语从句sothat引导目的状语从句时可译为“为了”,引导结果状语从句时可译为“以便”如：Ispeakloudlysothatallthestudentscanhearmeclearly.(目的状语从句)Marialikesthewoolendresssothatshedecidestobuyitimmediately.(结果状语从句)sothat引导目的状语从句时，表示“以便；为了”，从句中常使用can/could/may/might/will/would/should等情态动词或助动词；引导结果状语从句时，从句中一般不用can和may等词。so…that【知识点解析】sothat引导的目的状语从句之前不用逗号，而sothat引导的结果状语从句与主句之间往往有逗号相隔开（即略作停顿），意思是“因此；所以”。请比较：Heworkedhardathislessonssothathecouldgainhighgradesintheexams.他努力学习功课，争取考试能获得好成绩。Heworkedhardathislessons,sothathegainedhighgradesintheexams.他努力学习，结果考试获得了好成绩。so…that【知识点解析】四、“so…that…”和“such…that…”可以相互转换1.“so…that+含肯定意义的从句”可转换为“…enoughto…”.例如：Heissooldthathecangotoschool.→Heisoldenoughtogotoschool.（他到了上学的年龄。）2.“so…that+含否定意义的从句”可转换为“not…enoughto(dosth.)”或“too…to(dosth.)”。例如：so…that【知识点解析】Heissoyoungthathecan’tlookafterhimself.→Heisnotoldenoughtolookafterhimself./Heistooyoungtolookafterhimself.（他年龄太小，自己照顾不了自己。）3.可将so和such移至句首，再将主句的主、谓语倒装，以示强调。例如：Itissohotthatwedon’twanttogoout.→Sohotisitthatwedon’twanttogoout.（天气太热，我们不想出去。）Hemadesuchanexcellentspeechthateveryoneadmiredhim.→Suchanexcellentspeechdidhemakethateveryoneadmiredhim.（他作了如此精彩的演讲，人们都钦佩他。）so…that【知识点解析】4.somany/much…that…可转换为suchalotof…that…。例如：Therearesomanypeopleintheroomthatwecouldnotgetin.→Therearesuchalotofpeopleintheroomthatwecouldnotgetin.（房间里人太多，我们进不去。）so…that【知识点解析】补充内容：英语里可以用to,inorderto,soasto或sothat,inorderthat来表示目的。区别是：1)to,inorderto,soasto引导的是目的状语短语，构成简单句；2)sothat,inorderthat引导的是目的状语从句，构成复合句，并且从句中谓语动词常与can,could,may,might等情态动词连用。如：so…that【知识点解析】Hegotupearlyto/inorderto/soastocatchthefirstbus.他早起为了赶上第一趟车。Speakclearlysothateverybodycanunderstandyou.请说清楚一点，这样每个人都能听懂。so…that【知识点解析】注意：1)sothat和inorderthat的区别：sothat引导的从句只能放在主句之后，而inorderthat引导的从句既可放在主句前也可放在主句后。另外，sothat还可引导结果状语从句，意为“因此，结果”，但inorderthat不能。例如：Hewasveryhumoroussothatwelikedhimverymuch.他非常幽默，因此我们非常喜欢他。so…that【典型例题】1.It’s_______goodweather_______wecangoouttoenjoyapleasantpicnic.A.sucha;thatB.so;thatC.so;asD.such;that答案：D解析：句意：今天是那么好的天气，以至我们能出去享受一次令人愉快的野餐。So+形容词/副词+that+从句，表示如此的……以至于……。Such+（a/an）(形容词)+名词/名词短语+that+从句，表示如此……的事物以至于……。Weather天气，不可数名词。故排除AB，结合句意，故选D.so…that【典型例题】2.Itis______aninterestingbook______Iwanttoreaditoncemore.A.so;thatB.such;thatC./;sothatD./;suchthat答案：B解析：句意：这本书如此有意思以至于我想再读一遍。So,如此，那么，用法是so+形容词+that从句，such，如此，那么。用法是：
