雅思写作要想取得高分，掌握重难点句式必不可少。而句子是按照一定的语法规律组成的。表达一个完整的意义，一个英文句子一般由两部分构成，即主语部分和谓语部分，这两部分也叫做句子的主要成分。句子的次要成分包括宾语、定语、状语、表语等灵活掌握关键句型，雅思写作不用愁。

1."better…than…"句型

Bettermylifeshouldbeendedbytheirhate,thanthathatedlifeshouldbeprolongedtolivewithoutyourlove.

2."asitwere"是一个非常常用的插入语，意思是"好象"，"可以说"等。

Apieceofironnearamagnet,thoughapparentlyseparatefromit,feels,asitwere,thethreadsofthisattachment.

3.复杂结构，在下面例句中，由于anyone的定语从句过长，把谓语mustrealize提到定语从句之前。Thoughfaithandconfidencearesurelymoreorlassforeigntomynature,Idonotinfrequentlyfindmyselflookingtothemtobeable,diligent,candid,andevenhonest.Plainlyenough,thatistoolargeanorder,asanyonemustrealizewhoreflectsuponthemannerinwhichtheyreachpublicoffice.

4."not…anymorethan…"为："不能……，正如不能……"。

Onecannotlearntosketchandexpresshimselfgraphicallyonlybyreadingaboutitanymorethanonecanlearntoswimwhilestandingbythepool.

5."Bythatasitmay"是"Letitbethatasitmay"的省略形式，是由"be"引起的另外一种假设结构，意思是"虽然如此，尽管这样"。

Itissaidthatthenervepoisonisthemoreprimitiveofthetwo,thatthebloodpoisonis,sotospeak,anewproductfromanimprovedformula.Bethatasitmay,thenervepoisondoesitsbusinesswithmanfarmorequicklythanthebloodpoison.

6."ifatall"是一个由"if"引起的主谓结构不完整的短句结为"即将……"，"即使……"等。

Icanseeonlywithgreatdifficulty,ifatall.

7.由there引起的句型容易产生复杂的句子结构.

Therehavebeenopeneduptothevastandexcellentscience,inwhichmyworkisthebeginning,waysandmeansbywhichothermindsmoreaccuratethanwinewillexploreitsremotecorners.

8."rangefrom…to…"结构。这是一个常见结构，译时很多情况下应变通处理，不能完全依靠辞典上的释义。

Computerapplicationsrangefromanassemblylinecompletelyrunbycomputerstoachildrentoyrespondingtoremotesignals.

9."theway…"结构

Ialwaysthoughtshewasacommon-sensepersonwhodiscussedthingsthewaytheyoughttobediscussed.

10.复杂宾补结构

Inrecentyears,thedevelopmentofsensitiveandaccuratemeasuringequipmenthasmadeitpossibletomeasuretheacuityofhearingofanyindividualatdifferentfrequencies.

11.某些分隔结构

1)动词短语相关部分被分隔(当"makeuseof"，"takenoticeof"，"payattentionto"，

等动词短语变成被动语态时)。Useismadeofsolarenergyinheatinghouses.

2)双重定语引起的分隔。

Butthereisofcultureanotherview,inwhichnotsolelythescientificpassion,thesheerdesiretoseethingsastheyare,naturalandproperinanintelligentbeing,appearsasthegroundofit.

12."tobedoing…when…"是一个句型，多译为"某人正在做……时，突然……"。在简单的句子中容易看出，一旦句子变得复杂一些，可能就不太容易识别这种句型。

Shesaidsheandafriendhadgoneouttodinnerthatnight,andwerewalkinghometogetheratabout10o'clock,whena"verybig,verytallman",accostedthemanddemandedtheirpurses.

13."too…to"句型

ThenIrememberedhowoftenI,too,hadbeenindifferenttothegrandeurofeachday,toopreoccupiedwithpettyandsometimesevenmeanconcernstorespondtothesplendorofitall.

14."somuchthat…"句型

ButhedevelopedgraduallyaverymusicalEnglish.Helearnttowritesentencesthatfallawayontheearwithamistylanguoranditdelightedhimsomuchthathecouldneverhaveenoughofit.

15."when"引导状语从句有时并不好译，不能一看到when从句就考虑译为"当……的时候"，它还有许多种译法。Anythingisbetterthannottowriteclearly.Thereisnothingtobesaidagainstlucidity,andagainstsimplicityonlythepossibilityofdryness.Thisisariskthatiswellworthtakingwhenyoureflecthowmuchbetteritistobeboldthantowearacurlywig.

16."not…because…"，有时可否定前面，有时可否定because本身，往往出现歧义。应根据上下文面判定。

In1200theearthwasnotthecenteroftheuniversebecausethemajoritythensupposeditwas;nor,becauseshehadmorereaders,wasEllawheelerWilcoxabetterpoetthanFatherHopkins.

17."so…that,such…that"是一个普通的句型，但在同一个句子里有两处使用它却比较少见。

Thetruthis,thatinonepointofview,thismatterofnationalliteraturehascometosuchapasswithus,thatinsomesensewemustturnbullies,elsethedayislost,orsuperioritysofarbeyondus,thatwecanhardlysayitwilleverbeours.

18."bydoing…"结构。这个结构的意思是"通过(做)……"，但翻译实践中不能拘泥于这种释义，不少情况下需要灵活变通。

Thehippos,bydepositingdunginthewater,fedthefishthatsupportthestorksthatdestroytheraretrees.

19.下面例句为一倒装句，主语很长，而且又含有非常复杂的句型。这是以形容词作表语的倒装，翻译实践中多把倒装部分译到最前面。

Nolessobviousisthefacttherearegreatnumbersofpeoplesoconstitutedorsobroughtupthattheycannotgetsomuchpleasureoutofprocessesandexperiencesresultinginapoorerlifelessfullofmeaning.

20."what…of"句型

IcannotsayofmyselfwhatJohnsonsaidofPope:Heneverpassedafaultunamendedbyindifference,norquitteditbydespair.IdonotwriteasIdo;IwriteasIcan.

21.英语的一个习惯用法是：当否定谓语think(believe)时，实际上是否定其后面的宾语从句。否定就落在宾语从句上。这样宾语从句就变成了双重否定，译时可以按双重否定译，也可按肯定来译。

Itisavaluablework.Idonotthinkanyonewritessowellthathecannotlearnmuchfromit.

22."tohavenot…(as)tosee…"中的不定式也有否定意味。

Hehadnotthegoodbreedingtoseethatsimplicityandnaturalnessarethetruestmarksofdistinction.

23."Itoccurredtosb.that…"意为"突然想到"，"Itdawnedonsb.that…"."突然想起"等。从句是想起的内容。

Irememberoncebeingonabusandlookingatastranger.Hesuddenlylookedbackatme-i.e.oureyesmet.Myinstinctivereactionwastoavertmygaze.ItoccurredtomethatifIhadcontinuedtomaintaineyecontact,Iwouldhavebeenrudeandaggressive.

24."Itfollowsthat…"="Ithappensasaresult…"常常被译为"由此可见"，"因此"，"从前"，"可以推断"等等。

Itfollowsthatthehousewifewillalsoexpecttobeabletohavemoreleisureinherlifewithoutloweringherstandardofliving.Italsofollowsthathumandomesticservantswillhavecompletelyceasedtoexist.

25."that'sallthereistoit"，意思是"也不过如此而已"。可根据上下文视情况处理。

IfI'mtouched,I'mtouched-that'sallthereistoit.

26."Thechancesarethat…"是一句型，译为"有可能……"。

Thechancesareyouwillneverattemptthatspeedwithpoetryorwanttoracethoughsomepassagesinfictionoverwhichyouwishtolinger.

27.Feel,see,leave引起宾语的宾语补足语，或在被动语态中引起主语补足语的某些惯用句型，有时see和feel这两个词的被动式不大好译。遇到这种情况应挖掘其深层含义，不要拘泥于表面形式。

Theeducationoftheyoungisseentobeofprimaryimportance.

28.某此以no,nowhere,never,not…bout,not…any,nothingbut,hardly,scarcely,seldom等否定词语引出的一些结构。

InevergopastthetheatrebutIthinkofhislastperformance.

29.某些用choicebetween,toknowbetter,whetheror,shouldhaveavoided(或donebetter)等表示从两种做法中选取一种更好的做法Thenwearefacedwithachoicebetweenusingtechnologytoprovideandfulfilneedswhichhavehithertobeenregardedasunnecessaryor,ontheotherhand,usingtechnologytoreducethenumberofhoursofworkwhichamanmustdoinordertoearnagivenstandardoflibing.

30.某些省略情况，应清单确认省略的内容。

Thecountryhadgrownrich,itscommercewaslarge,andwealthdiditsnaturalworkinmakinglifesofterandmoreworldly,commerceindeprovincializingthemindsofthoseengagedinit.

31.修饰成分(包括定语、定语从句、同位语从句等)多而长。

AcrossthecourtfromtheManhattanapartmentthatIhaveoccupiedforthepastfewyearsisadogthatoftenhurlsinsultsintothedarkness,afewofwhichmydogrefusestoacceptandmakesatartreply.

32.一些外位语，所谓外位修饰，指从句子结构和内容上不起主要信息表达功能的部分。其作用是从语气和连接上下文等方面进行补充。在翻译成汉语时，往往可独立成句，外形上不保留修饰的痕迹。

Ofcourse,nobodywashurtthistime,becausewehadallbeentodinner,noneofusbeingnovicesexceptingHastings;andhehavingbeeninformedbytheministeratthetimethatheinvitedhimthatindeferencetotheEnglishcustomthehadnotprovidedanydinner.

33."Every…not"和"All…not"结构

"Every…not"表示"不见得每个……都是……";"All…not"表示"不见得所有……都是……"的意思。

Everymanisnotpolite,andallarenotborngentlemen.

34."mayaswellnot…as"结构

此结构可译为"与其……不如不……"。

Onemayaswellnotknowathingatallasknowitbutimperfectly.

35."haveonlyto…do"结构

此结构表示"只须(消)……就能……"的意思。

WehaveonlytoturntothatextraordinarydiscoverymadebyEdisontoseethesignificanceofit.

36."not(no)…unless…"句型

Noincreaseinoutputcanbeexpectedunlessanewassemblylineisinstalled.
