以下为本文档部分文字说明：

备课资料连词连词是在词、短语、从句或句子之间起连接作用的词,按其在句子中的作用分为并列连词和从属连词。并列连词表示词、短语、句子彼此之间意义相关,层次相同,句法功能也相同。从属主要作为语意上分清主次的

手段,所谓从属就是把次要的思想内容置于从属地位,从而突出句子的主要思想。常见的并列连词有and,both...and,aswellas,notonly...butalso,neither...nor,

either...or等等。常见的从属连词when/while/as,since,before,after,once,until/till,because,nowthat(既然),although/though,evenif/though,aslongas

,sothat,asif/though,where,wherever,however等等。本模块主要介绍几个引导让步状语从句的从属连词。1.although/though引导状语从句的although和th

ough同义,用法基本相同。前者较正式,多置于句首;后者较通俗,口语化,也可置于句末。如:Hedidn’tlightthefirethough/althoughitwascold.Althoughheisquiteold,hestilljogse

veryday.Hesaidhewouldcome;hedidn’t,though.Hedidn’ttellmewherehehadbeen,butIknowit,though.引导倒装的让步状语从句只能用though。Muchthough

Iloveit,I’llnotbuyit.注意:二者皆不可与并列连词but连用,但可与yet/still连用。Thoughthesorebehealed,yetascarmayremain.(谚)伤口虽然愈合,但伤疤留下了。2.however/but两者都表示

转折“但是”,但词性不同。however作此义讲是副词,故不能连接并列分句而需另起一句,且位置灵活;but是并列连词,可以连接并列分句。Theproblemwasdifficult;however,Iworkeditout.Iboughtmysis

terashirt,butshedidn’tlikeit.另外,however还可作“无论……”解,构成“howeveradj./adv./状语+主语+谓语”结构。Howevermuchheearns,heisstillunsatisfied.Imustcatchhim,howeverfasth

eruns.3.while表让步“虽然”,相当于although。WhileIunderstandwhatyousaid,Ican’tagreewithyou.
