so...that...表示“如此……以至于……”，用来引导结果状语从句。易混辨析so...that...，such...that...so...that...和such...that...都可以表示“如此……以至于……”的意思，引导结果状语从句。但such是形容词，so为副词，常构成以下结构：⑤HeissocleveraboythathecanlearnEnglishquickly.＝HeissuchacleverboythathecanlearnEnglishquickly.他是个非常聪明的男孩，学英语很快。牛刀小试句型转换(1)Sheissuchanhonestgirlthateverybodytrustsher.→Sheis________________thateverybodytrustsher.答案：sohonestagirl单项填空(2)—________finedayitistoday!—Yes，thesunshineis________beautifulthatI’dliketogoswimminginthesea.A．How；such B．Whata；veryC．How；so D．Whata；so解析：选D。第一个空考查how和what引导的感叹句的区别。day是可数名词，所以应是whatafineday＝howfineaday。第二个空考查so＋adj.＋that从句结构引导结果状语从句的用法。WHOAMI?OvertimeIhavebeenchangedquitealot.IbeganasacalculatingmachineinFrancein1642.AlthoughIwasyoungIcouldsimplifydifficultsums.IdevelopedveryslowlyandittooknearlytwohundredyearsbeforeIwasbuiltasananalyticalmachinebyCharlesBabbage.AfterIwasprogrammedbyanoperatorwhousedcardswithholes,Icould“think”logicallyandproduceananswerquickerthananyperson.Atthattimeitwasconsideredatechnological译文助读revolutionandthestartofmy“artificialintelligence”．In1936myrealfather，AlanTuring，wroteabookabouthowIcouldbemadetoworkasa“universalmachine”tosolveanydifficultmathematicalproblem.Fromthenon，Igrewrapidlybothinsizeandinbrainpower.Bythe1940sIhadgrownaslargeasaroom，andIwonderedifIwouldgrowanylarger.However，thisrealityalsoworriedmydesigners.Astimewentby，Iwasmadesmaller.FirstasaPC(personalcomputer)andthenasalaptop，Ihavebeenusedinofficesandhomessincethe1970s.Thesechangesonlybecamepossibleasmymemoryimproved.Firstitwasstoredintubes，thenontransistorsandlateronverysmallchips.AsaresultItotallychangedmyshape.AsIhavegrownolderIhavealsogrownsmaller.Overtimemymemoryhasdevelopedsomuchthat,likeanelephant,IneverforgetanythingIhavebeentold!AndmymemorybecamesolargethatevenIcouldn’tbelieveit!ButIwasalwayssolonelystandingtherebymyself，untilinearly1960stheygavemeafamilyconnectedbyanetwork.IwasabletosharemyknowledgewithothersthroughtheWorldWideWeb.Sincethe1970smanynewapplicationshavebeenfoundforme.Ihavebecomeveryimportantincommunication，financeandtrade.Ihavealsobeenputintorobotsandusedtomakemobilephonesaswellashelpwithmedicaloperations.IhaveevenbeenputintospacerocketsandsenttoexploretheMoonandMars.Anyhow，mygoalistoprovidehumanswithalifeofhighquality.IamnowtrulyfilledwithhappinessthatIamadevotedfriendandhelperofthehumanrace!我是谁？经过一段时间我已经被改变了很多。1642年我在法国诞生时是一台计算机器。尽管当时我还年轻，但是我能简化(simplify)一些复杂的数学题(sum)。我发育缓慢，差不多到了两百年之后，查
