什么样的句子叫让步状语从句

引导让步状语从句的连词主要有以下这些：though,although,as; even if,even though; whether...or...; no matter+疑问词,疑问词-ever.下面对这些连词引导的让步状语从句作一说明.\x0d（1）though,although表示“虽然,纵然”之意.\x0d这两个连词意思大致相同,在一般情况下可以互换使用.在口语中,though较常使用,although比though正式,二者都可与yet,still或nevertheless连用,但不能与but连用.例如：\x0dThough/Though he was worn out,(still) he kept on working.虽然他已经精疲力竭了,但仍然继续工作.\x0dAlthough/Though he is very old,(yet)he is quite strong.他虽然年纪大了,身体还很健壮.\x0d值得注意的是,although引导的让步状语从句位于主句之前的情况较多,though引导的让步状语从句可位于主句之前或主句之后.例如：\x0dShe passed the examination though she had not studied very hard.她虽然不用功学习,考试却及格了.\x0d（2）as,though表示“虽然……但是”,“纵使……”之意.\x0das引导的让步状语从句必须以部分倒装的形式出现,被倒装的部分可以是表语、状语或动词原形,though间或也用于这样的结构中,但although不可以这样用.例如：\x0dObject as you may,I ll go.(=Though/Although you may object,I ll go.) 纵使你反对,我也要去.\x0dFast as you read,you can t finish the book so soon.纵然你读得快,你也不能这么快读完这本书.\x0d（3）even if,even though 表示“即使……”,“纵使……”之意.\x0d这两个复合连词的意思基本相同.它们常可互换使用,但意义有细微差别.even if引导的让步从句含有强烈的假定性,而even though引导让步状语从句时,是以从句的内容为先决条件的,也就是说,说话人肯定了从句的事实.例如：\x0dWe ll make a trip even if/though the weather is bad.即使天气不好,我们也要作一次旅行.\x0dEven if he is poor,she loves him.(=He may be poor,yet she loves him.)即使他很穷,但她还是爱他.\x0dEven though he is poor,she loves him.(=He is poor,yet she loves him.)尽管他很穷,但她还是爱她.\x0d（4）whether...or...表示“不论是否……”,“不管是……还是……”之意.\x0d由这一个复合连词引导的让步状语从句旨在说明正反两个方面的可能性都不会影响主句的意向或结果.例如：\x0dYou ll have to attend the ceremony whether you re free or busy.不管你忙不忙,都要参加这个典礼.\x0dWhether you believe it or not,it s true.无论你是否相信,这都是真的.\x0d（5）“no matter+疑问词”或“疑问词-ever”的含义为“……都……；不管……都……”,它们引导的让步状语从句可以互换.例如：\x0dNo matter who you are,you must keep the law.(=Whoever you are,you must keep the law.不管你是谁,你都要遵纪守法.\x0d但“no matter+疑问词”结构只能引导让步状语从句,而“疑问词-ever”还可以引导名词性从句.例如：\x0d此外,有时while也可以引导让步状语从句,但一般要位于句首.例如：\x0dWhile I like the colour,I don t like the shape.我虽然喜欢那颜色,但不喜欢那形状.\x0d综上所述,我们可以看出,学习让步状语从句的关键是关联词的选用；其次,要注意的是由as引导的让步状语从句要用倒装语序.
