讓步狀語從句的用法有：
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引導的讓步狀語從句必須以部分倒裝的形式出現,被倒裝的部分可以是表語、狀語或動詞原形。
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，even if引導的讓步從句含有強烈的假定性,可用來表示與事實相反的假設,但不能用來描述已經發生的事實.而even though引導讓步狀語從句時,是以從句的內容為先決條件的,即說話人肯定了從句的事實,表示已經發生了的事.
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+疑問詞”或“疑問詞-ever”的含義為“……都……；不管……都…"。
eg. No matter what happened, he would not mind. (=Whatever happened, he would not mind.)
