　　but 与 however的用法区别

　　两者均可表示转折或对比，意为“但是”、“可是”、“然而”等，但有区别：

1. 表示转折时，but 是连词。

   如：

   He is young but very experienced. 他虽年轻，但经验很丰富。He has three daughters but no sons. 他有3 个女儿，但没有儿子。

   He likes sports, but his wife likes music. 他喜欢运动，而他妻子则喜欢音乐。

2. however 表示“然而”、“可是”时，有的词书认为它是连词，有的词书认为它是副词。之所以将其视为副词，也许是因为像许多副词一样不仅能位于句首，而且能位于句中(注意前后使用逗号)，甚至句末 (注意其前也用逗号)。

   如：

   Later, however, he changed his mind. 可是他后来改变了主意。

   He hasn’t arrived. He may, however, come later. 他还没有到，不过他等会儿可能会来。

   He said that it was so; he was mistaken, however. 他说情况如此，可是他错了。

   注：以上各例中的 however 不能换成 but，但可用 but 来改写。如：

   He said that it was so, but he was mistaken. 他说情况如此，可他错了。

3.  当连接两个句子时，其前通常应用分号，或另起新句。

   如：

   It’s raining hard; however, I think we should go out. / It’s raining hard. However, I think we should go out. 雨下得很大，但我想我们还得出去。

   注：上例中的 however 不能换成 but，但可用 but 来改写 (注意所用标点的变化)。

   如：

　　It’s raining hard, but I think we should go out.

　　but 和however 的区别主要是：从语义上看，but所表示的是非常明显的对比，转折的意味较however要强。从语序上看，but总是位于所引出的分句之首，而however却可位于句首、句中和句末，同时从标点符号上看，but之后一般不得使用逗号，而however则必须用逗号与句子其它部分分开。例如：
　　1.A miracle is something that seems impossible but happens anyway.
　　奇迹就是看似不可能，却发生了。
　　2.English has hurt me a thousand times, but I still regard it as my first love.
　　英语伤我千百遍，我待英语如初恋。
　　3.The deal with Chelsea may not, however, be dead.
　　不过，与切尔西的交易或许还有戏。
　　4.What is missing, however, is an internal, artistic cohesion.
　　不过，缺乏的是一种内在的艺术凝聚力。

• but： 口语常用词，语气较强，泛指与前述情况相反。

• however： 表转折关系，语气稍弱于but，连接性也弱一些，因而常作插入语。
