讓步狀語(yǔ)從句的用法有：
1、though, although表示“雖然，縱然”之意, 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
eg. Although/Though he was exhausted, (still) he kept on working.
2、as, though表示“雖然……但是”，“縱使……”之意。as引導(dǎo)的讓步狀語(yǔ)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(yǔ)、狀語(yǔ)或動(dòng)詞原形。
eg. Object as you may, I’ll go.(=Though/Although you may object, I’ll go.)
3、even if, even though 表示“即使……”,“縱使……”之意, 表示假設(shè)，even if引導(dǎo)的讓步從句含有強(qiáng)烈的假定性,可用來(lái)表示與事實(shí)相反的假設(shè),但不能用來(lái)描述已經(jīng)發(fā)生的事實(shí).而even though引導(dǎo)讓步狀語(yǔ)從句時(shí),是以從句的內(nèi)容為先決條件的,即說(shuō)話人肯定了從句的事實(shí),表示已經(jīng)發(fā)生了的事.
eg. We’ll make a trip even if the weather is bad.
We made a trip even though the weather was bad.
4、whether...or...表示“不論是否……”,“不管是……還是……”之意。
eg. Whether you believe it or not, it's true.
5、“no matter+疑問(wèn)詞”或“疑問(wèn)詞-ever”的含義為“……都……；不管……都…"。
eg. No matter what happened, he would not mind. (=Whatever happened, he would not mind.)
