although和however

Question

两个意思差不多，但具体用法是怎样的，请指教。就是在怎样的语言环境?

Answer 1

although 只起连词作用，不充当句子的成分，例如：

Although he is known to only a few, his reputation among them is very great. 虽然知道他的人不多，但他在这些人中名声却很响。

Although I was only six, I can remember seeing it on TV.  虽然那时我只有6岁，我依然记得在电视上见过它。

Although they're expensive, they last forever and never go out of style...  尽管价格昂贵，但它们经久耐用，永不过时。

however 是副词，既起连词作用，也充当句子成分，例如：

You should always strive to achieve more, however well you have done before.   无论之前取得何等辉煌的成就，都应该不断努力进取。【修饰副词 well】

However hard she tried, nothing seemed to work.    ä¸ç®¡å¥¹æ€Žä¹ˆåŠªåŠ›ï¼Œå¥½åƒéƒ½æ— æµŽäºŽäº‹ã€‚【修饰副词 well】

However we adopt health care reform, it isn't going to save major amounts of money.  ä¸ç®¡æˆ‘们采取何种医疗改革措施，都省不下太多钱。 【本身就是程度状语】
