语法讲解:
1、连词的含义:连接词与词、短语与短语、或引导从句的词叫连接词。
2、连词的分类:连词分为并列连接词和从属连接词两种。
1、并列连接词连接并列的词、短语、从句或句子。常见的并列连接词有:and(和),but(但是),or(或者,否则),nor(也不),so(所以),however(然而,无论如何),for(因为),still(可是),aswellas(也),both..and...(...和...),notonly...butalso...(不但…而且…),either…or…(或…或…),neither…nor…(既不…也不…)等。
2、从属连接词用于引导从句,常见的从属连接词有:
when(当…时候),while(正当…时候),after(在…之后),before(在…之前),since(自从),until(直到),although/though(虽然),if(假如),as(如…一样;由于),as…as…(和…一样),asfaras(就…而言),aslongas(只要),assoonas(一…就…),evenif(即使),becau(因为),unless(除非),than(比…),whether(是否…),inorderthat…(为了),so…that…(如此…以致),sothat…(以便),nowthat…(现在既然),bythetime…(到…时候),everytime…(每当),asif…(仿佛),nomatterwhen(或whenever)(无论何时),nomatterwhere(或wherever)(无论在哪里)等。
[辨析]
(1)becau、as、since、for的用法:becau(因为)表示原因的语气最强,常表示必然的因果关系,从句一
Sundayisstillaquestion.(下个星期天是不是个好天还是个问题)(引导主语从句)/Pleaaskhimwhethertogotherewitharaincoatornot.(请问一下带不带雨衣去那儿)(作动词的宾语)/Hainanistheplacetobe,whetherit’ssummerorwinter.(海南是个该去的地方无论冬夏)(引导让步状语从句)/Plealetmeknowwhetheryouneedmyhelp.(请告诉我你是否需要我的帮助)(引导宾语从句)(如果换成if则还可能表示“如果你需要我的帮助请告知”)
(3)while、when、as的用法区别:while常表示一个较长的动作,它引导的从句动作与主句的动作是同时发生的、是平行的;when可以表示较短的动作也可以表示较长的动作,主句和从句的动作可以同时发生也可以先后发生;as与上两词同义,可替换while和when,表示主句和从句的动作同时发生,常译为“一边……一边……”。如:PleadonottroublemewhileIamwritingmyhomework.(我写作业时请不要打扰我)/I’llgohomewhenIhavefinishedmyjob.(我干完了活儿就回去)/Theywererunningquicklyacrosstheroadwhentheyheardthesoundofatruckcoming.(他们正快速地穿过马路忽然听到了卡车开来的声音)/Aswewalkedinthedarkstreet,wesangsongsandtalkedloudly.(当我们在黑洞洞的街上走路时我们高声地唱歌说话)
(4)till/until与not…till/until的区别:前者表示一个延续性的动作,后者表示一个才开始的动作。如:Iwillstayhereandwatchthebabyuntilyoureturn.(我会呆在这里看着娃娃直到你回来)(stay这个动作一直进行到你
return)/Theywon’tgoonworkinguntiltheygetwhattheythinkisreasonable.(他们要到获得了他们认为合理的东西时才会继续干下去的)
另外till与until基本可以互换,但是在句首时只能用until,不能用till.如:Untilthelastminuteofthematchwekeptplaying.(我们坚持到比赛的最后一分钟)/Notuntilhehadfinishedhisworkdidhegohome.(直到做完工作他才回家)(倒装句)
(5)though与although的区别:两个词都表示“虽然”,均不可以与but同时使用,但在句中可加still或yet连用。although“尽管、虽然”仅作连词,比较正式,一般可以换为though;though“虽然、尽管、即使”,还可以与even连用(=evenif),表示“即使、纵然”,作副词时意思是“然而、不过”,不能放在句首。如:Hepasdtheexamsalthoughillnesspreventedhimfromgoingtoclass.(尽管疾病使他无法上课但是他还是通过了考试)/shewon’tleavetheTVt,eventhoughherhusbandiswaitingforherforthesupper.(她不愿离开电视机虽然丈夫在等她吃饭)/Itwasaquietparty.Ihadagoodtime,though.(这是个不热闹的聚会尽管如此我还是玩得很开心)
(6)preferto…ratherthan…与prefer…to…的区别:preferto…ratherthan…后面都是用动词原形,prefer…to…都是用动名词或名词。如:IpreferEnglishtoJapane.(与日语相比我更喜欢英语)/IprefertolearnEnglishratherthanlearnJapane.(与日语相比我更喜欢学英语)
