有共同之處,也有不同點.兩都可用來引導(dǎo)讓步狀語從句,表示漢語的"雖然……但是……".但不能說although / though...but.如：不能說：Although / Though he is very old,but he is still quite strong.句中的but 應(yīng)去掉.Although是較為正式的用語,引導(dǎo)的從句多位于主句前,though多用于非正式文體中,引導(dǎo)的從句位于主句前后都可.
注意：though可用于倒裝句中,although不可.如：Young though he is ,he has worked for a few years.他雖然年輕但已經(jīng)工作好幾年了.
