連詞

conjunction小組成員：田焜鵬，韋棟，明謠連詞是一種虛詞，它不能獨(dú)立擔(dān)任句子成分。用來連接詞，短語，從句與句子。

連詞主要可分為兩類：并列連詞從屬連詞并列連詞表示詞，短語，從句或句子之間具有并列關(guān)系。可以表示并列關(guān)系，轉(zhuǎn)折關(guān)系，和因果關(guān)系。and(和)both…and（和,兩者都）or（或者）neither…nor（既不…也不…）notonly…butalso(不但…而且…)aswellas(和,也,除…外,而且)

1.表示并列關(guān)系的連詞：aswell(也,而且,)用于句末.1.Heisascientist,butheisapoetaswell.2.Heisascientistaswellasapoet.4.BothNewYorkandLondonhavetrafficproblems.3.Aretheycomingaswell?2.表示轉(zhuǎn)折關(guān)系的連詞:butwhile(而,雖然)yet(可是)however(而)Somebodyborrowedmypen,butIdon’trememberwho.Hesaidhewasourfriend,yethewouldhelpus.4.表示因果關(guān)系的連詞

soforthus(因此)therefore

（因此）consequently（因而，所以）1.Thechildhasabadcough,sohismothertakehimtothedoctor.2.Youaresupposedtogetridofcarelessness,foritoftenleadstoseriouserrors.注意:for通常不能用于句首，也不能單獨(dú)使用。二.從屬連詞是用來引導(dǎo)連接主句和從句的連詞。分為引導(dǎo)名詞性從句的連詞和引導(dǎo)狀語從句的連詞。（分為連接代詞和連接副詞）(1).that,whether,if不充當(dāng)成分.(2).連接代詞who,whom,which,what

充當(dāng)主,賓,定,表語等.(3).連接副詞when,where,how,why狀語.1.引導(dǎo)名詞性從句的連詞（1）That，whether，if不充當(dāng)句子成分的。其中that不僅沒有充當(dāng)句子成分，而且沒有詞義，在句子中只起連接作用。而if，whether雖然不充當(dāng)句子成分，但有詞義，表示“是否”。如Herepliedthathewasgoingbytrain.Iwonderifit’slargeenough.IworryaboutwhetherIhurtherfeelings.

（2）連接代詞who，whom，which，what充當(dāng)主，賓，定，表語等。TheboyswhoareplayingfootballarefromClassOne.（充當(dāng)主語）Heisnotwhatheusedtobe.（充當(dāng)表語）Whichteamhaswonthegameisnotknownyet.（充當(dāng)定語）HeaskedwhomIborrowedthemoneyfrom.（充當(dāng)賓語）(3).連接副詞when,where,how,why

2.引導(dǎo)狀語從句的連詞(1).時(shí)間:when,while,as當(dāng)…時(shí)as+瞬間,延續(xù)性動(dòng)詞“一邊…一邊”

since,till/until,assoonas(一…就),themoment/instant(一…就),Don’ttalkwhileyouareeating.She’sbeenplayingtennissinceshewaseight.ThemomentIfinishI’llgiveyouacall.(2).原因:asbecauseforsinceFor語氣最弱,引導(dǎo)的分句放在句末.Because語氣最強(qiáng),句首,句末均可.As(因?yàn)?置于句首.Since(既然)通常置于句首.(3).地點(diǎn):where,wherever,anywhereI’lltakeyouanywhereyoulike.(4).條件:if,unless=if…not,so/aslongas,suppose(that)假使DoyoumindifIopenthewindow?Don’tcomeunlessItelephone.注意：在條件狀語從句中，通常要用一般現(xiàn)在時(shí)表示將來意義，而不能直接使用將來時(shí)態(tài)。不過，有時(shí)條件的if后可能用will,但那不是表示將來時(shí)態(tài)，而是表示意愿或委婉的請求。如：Ifyouwillsitdownforafewmoments,I’lltellthemanageryouarehere.(5).讓步:though/although不與but連用.as(盡管),evenif/though(即使)however(無論怎樣),whatevernomatterhow/who/whichAlthoughtheyaretwins,theylookentirelydifferent.Whoeveryouare,youcan’tpassthisway.WheneverIseehimIspeaktohim.（6）.結(jié)果:So...that,such...thatIwenttothelecturesoearlythatIgotagoodseat.（7）.目的:sothat,inorderthatHe
