although和though的区别是：

1) "Although"常置于句首，语气较though强，且正规，多用于书面语中。

2)though还可用作副词(=however),置于句尾，而although则不可。如：She promised to come, yet hasn't turned up until now, though.

3)though可用于部分倒装句 式中，面although则不可。

如：Strange though it may seem, she still accepted the flower. =Although it seems strange, she still accept the flower.
