although与though的区别在于：
1. 用作连词
表示“虽然”，两者大致同义，可换用，只是 although 比 though 更为正式。例如：
Though/Although it was raining，we went there. 虽然下着雨，但我们还是去了那儿。
Though/Although it was barely four o’clock, the lights were already on. 尽管才四点钟，灯已经亮了。
Though/Although we are poor, we are still happy. 我们虽然穷，仍然很快活。
2. 用作副词
although 一般不用作副词，而 though 可用作副词，且一般放在句末(不放在句首)，意为“可是”,“不过”。例如：
It's hard work; I enjoy it though. 工作很辛苦，可是我乐意干。
He is looking fit, though. 但他看起来很健康。
You can count on him, though. 不过你可以指靠他。
