一、用作連詞

表示“雖然”，兩者大致同義，可換用，只是 although 比 though 更為正式：

Though [Although] it was raining，we went there. 雖然下著雨，但我們還是去了那兒。

Though [Although] it was barely four o’clock, the lights were already on. 盡管才四點鐘，燈已經亮了。

Though [Although] we are poor, we are still happy. 我們雖然窮，仍然很快活。

二、用作副詞

although 一般不用作副詞，而 though 可用作副詞，且一般放在句末(不放在句首)，意為“可是”、“不過”：

It’s hard work; I enjoy it though. 工作很辛苦，可是我樂意干。

He is looking fit, though. 但他看起來很健康。

You can count on him, though. 不過你可以指靠他。

三、用于習語

在 as though(好像，仿佛)，even though(即使，縱然)等固定短語中不能用 although：

She closed her eyes as though she were tired. 她閉上眼，仿佛很疲勞似的。

We felt as though we had witnessed the whole thing. 我們感到仿佛目擊了整個這件事似的。

He is an honest man, I must say, even though I have opposed him. 盡管我反對過他，我還得說他是一個誠實的人。

She was always afraid of men, even though she had lots of boyfriends. 盡管她有很多男朋友，她總是害怕男人。

四、用于倒裝

though 引導的讓步狀語從句可用部分倒裝的形式(注意：倒裝后位于句首的名詞之前不用冠詞)，但 although 一般不這樣用：

Poor though I am, I can afford it. 我雖窮，但這東西還是買得起的。

Child though he was, he did quite well. 他雖是孩子，但干得很好。
