however和but的区别

ut 和however 都表示转折,但是,然而.最明显的区别就是however 是单独使用的,文中出现在一句话的结尾,一段话的开始,有逗号隔开.
比较：He used to be a good driver,however,he had a traffic accident yesterday.
He used to be a good driver,but he had a traffic accident yesterday.
He used to be a good driver but he had a traffic accident yesterday.
另外but 还表示除.之外,常用结构have no choice but to do除了.之外别无选择
but 还可以直接接副词.But now,I have no choice but to forget out of my willingness.
可如今,我只能逞强自己选择遗忘.而however不可以.
however除了表示转折以外,还可接其他词,如however much/many/far/often/long等,此时表示无论多...可以相应换成no matter how +much/many/far/often/long
比较People are going to take however much you're willing to give.人永远不会嫌自己拿得多.
In my opinion,parents do not owe their children an inheritance,no matter how much money they have.以我个人的观点,家长们不欠儿女们一份遗产,不论他们多么有钱.

but，however都是然而但是表示转折
区别
but是连词链接句子多用于句中无逗号
however是副词位于句中，句末，因为是副词因此一定要有逗号于句子隔开
