讓步狀語從句是狀語從句中的一種,其本身也是狀語從句.一般翻譯為“盡管……”或“即使……”,就是我們?nèi)粘Ｉ钪杏玫摹巴艘徊秸f……”的感覺.
使用的連詞
　　引導(dǎo)讓步狀語從句的連詞主要有以下這些：though, although,while, as; even if, even though; whether...or...; no matter+疑問詞,疑問詞-ever,regardless of+名詞/名詞短語/名詞從句,despite,in spite of.切記although不可與but連用
用法
　?。?）though, although表示“雖然,縱然”之意. 　　這兩個(gè)連詞意思大致相同,在一般情況下可以互換使用.在口語中,though較常使用,although比though正式,二者都可與yet, still或never,the less連用,但不能與but連用.
例如： 　　Although/Though he was exhausted, (still) he kept on working. 雖然他已經(jīng)精疲力竭了,但仍然繼續(xù)工作. 　　
?。?）as, though表示“雖然……但是”,“縱使……”之意. 　　as引導(dǎo)的讓步狀語從句必須以部分倒裝的形式出現(xiàn),被倒裝的部分可以是表語、狀語或動(dòng)詞原形,though也可用于這樣的結(jié)構(gòu)中,但although不可以這樣用.
例如： 　　Object as you may, I’ll go.(=Though/Although you may object, I’ll go.) 縱使你反對(duì),我也要去. 　　
（3）even if, even though 表示“即使……”,“縱使……”之意,含有一種假設(shè). 　　這兩個(gè)復(fù)合連詞的意思基本相同.它們?；Q使用,但意義有細(xì)微差別.even if引導(dǎo)的讓步從句含有強(qiáng)烈的假定性,可用來表示與事實(shí)相反的假設(shè),但不能用來描述已經(jīng)發(fā)生的事實(shí).而even though引導(dǎo)讓步狀語從句時(shí),是以從句的內(nèi)容為先決條件的,即說話人肯定了從句的事實(shí),表示已經(jīng)發(fā)生了的事.
例如： 　　We’ll make a trip even if/though the weather is bad. 即使天氣不好,我們也要作一次旅行. 　　
（4）whether...or...表示“不論是否……”,“不管是……還是……”之意. 　　由這一個(gè)復(fù)合連詞引導(dǎo)的讓步狀語從句旨在說明正反兩方面的可能性都不會(huì)影響主句的意向或結(jié)果.
例如： 　　You'll have to attend the ceremony whether you're free or busy. 不管你忙不忙,都要參加這個(gè)典禮. 　　
Whether you believe it or not, it's true.無論你是否相信,這都是真的. 　　
（5）“no matter+疑問詞”或“疑問詞-ever”的含義為“……都……；不管……都……” 　　它們引導(dǎo)的讓步狀語從句可以互換.
例如： 　　No matter what happened, he would not mind. (=Whatever happened, he would not mind.)無論發(fā)生了什么,他都不會(huì)介意的. 　　No matter who you are, you must keep the law.(=Whoever you are, you must keep the law.不管你是誰,你都要遵紀(jì)守法. 　　但“no matter+疑問詞”結(jié)構(gòu)只能引導(dǎo)讓步狀語從句,而“疑問詞-ever”還可以引導(dǎo)名詞性從句.例如： 　　Whatever (=No matter what) you say, I won’t believe you. (Whatever 引導(dǎo)讓步狀語從句)無論你說什么,我都不會(huì)相信你. 　　
I'll eat whatever (≠no matter what) you give me. (whatever引導(dǎo)賓語從句)你給我吃什么,我就吃什么. 　　
Whoever comes will be welcome. (Whoever 引導(dǎo)主語從句) 不管誰來都受到歡迎. 　　
此外,有時(shí)while也可以引導(dǎo)讓步狀語從句,但一般要位于句首.
例如： 　　While I like the colour, I don't like the shape.我雖然喜歡那顏色,但不喜歡那形狀. 　　
綜上所述,我們可以看出,學(xué)習(xí)讓步狀語從句的關(guān)鍵是關(guān)聯(lián)詞的選用；其次,要注意的是由as引導(dǎo)的讓步狀語從句要用倒裝語序. 　　讓步狀語從句表示：雖然,盡管,即使等概念,由although, though（盡管,即使）, however（無論怎樣）, whatever（無論什么）, whoever（無論誰）, whomever（無論誰）, whichever（無論哪個(gè)）, whenever（無論何時(shí)）, wherever（無論哪里）, whether（是否）, no matter (who, what, where, when, etc) （無論……）, even if（即使）, even though（即使）等詞引導(dǎo). 　　
如： We won’t be discouraged even if(=even though) we fail ten times.我們就是失敗十次也不泄氣. 　　
It was an exciting game, though / although no goals were scored.那是一場(chǎng)精彩的球賽,盡管一個(gè)球都沒進(jìn).(though, although不能與 but連用) 　　
Whether you believe it or not, it’s true.不管你信不信,這是真的. 　　
However (=No matter how) expensive it may be, I’ll take it.無論它有多貴,我也要買下它. 　　Don’t let them in, whoever(=no matter who) they are.不管他們是誰,別讓他們進(jìn)來. 　　
No matter what I say or how I say it, he always thinks I’m wrong.無論我說什么或怎么說,他總認(rèn)為是我錯(cuò).
特別提醒
　　1.no matter 　　what（who,which,when,etc.）與whatever（whoever,whichever,whenever,etc.）的區(qū)別：
　　當(dāng)引導(dǎo)讓步狀語從句時(shí),兩者相同,可以互換,但當(dāng)引導(dǎo)名詞性從句（主語從句,賓語從句,表語從句和同位語從句）時(shí)則只能用whatever（whoever,whichever,whenever,etc）.如上面最后兩個(gè)例句可改為： 　
　However pure the water looks,I do not want to drink it. 　
　I want to marry the man I love, no matter who he may be. 　　下面句子不能用no matter結(jié)構(gòu)(no matter不能引導(dǎo)名詞性從句）: 　　
Whoever comes back first is supposed to win the prize.(主語從句) 　
　I am ready to do whatever you want me to .（賓語從句） 　　
例證： 　　Whatever you did, I will accept.為讓步狀語從句. 　
　I will accept whatever you did.為賓語從句. 　　
2. as 引導(dǎo)讓步狀語從句的用法
　　引導(dǎo)讓步狀語從句時(shí),as意為“雖然,盡管”,通常從句要倒裝,倒裝的方法是將從句的表語或狀語放在as之前,而用though引導(dǎo)讓步狀語從句時(shí)句字則不必倒裝（口語中也可倒裝）. 　　e.g. Heavily as it was raining outside, they started out very early. 　
　Young as he is, he knows a lot=Though he is young 或Young though he is, he…. 　　他雖然年輕,但懂得很多.(though 也有這種用法,可以替換as,但although沒有這種用法) 　　though還可以用作副詞,放在句末.如： 　　It was hard work;; I enjoyed it, though=It was hard work, but I enjoyed it.那工作很苦,但是我喜歡干. 　　
3.用though/although, as 引導(dǎo)讓步狀語從句時(shí),句中不能用but表示轉(zhuǎn)折語氣. 　　
不能說：Though he looks weak, but he is healthy. 　　
而要說：Though he looks weak, he is healthy. 　　
或者說：He looks weak, but he is healthy. 　　我自己認(rèn)為讓步就是存在一定條件下的說法. 　　
4 . however 用作副詞,不可連接句子. 但可置于第二句的句首、句末或句中.要特別注意標(biāo)點(diǎn)的使用.
eg: Alice is a good student．However, she has one shortcoming． 　　
He has not arrived. He may, however, come later. 　　
The composition is all right. There is room for improvement, however. 　　
5. 除以上提到的從句連詞外,表示讓步的介詞短語有despite, in spite of, 后接名詞.eg. Despite all these facts, we cannot ignore the advantages of learning through internet.
