四、however作“但是，可是”讲时可用作连词
旧观点：传统语法中，however作“但是，可是”讲时只能用作副词，不能用作连词，Micheal Swan在《牛津英语用法指南》中特别指出：不要把连词however（意为“无论怎样”in whatever way,no matter how）与副词however（意为“但是，可是”but,on the other hand）混用。《朗文当代英语词典》的看法与上同。
新观点：however作连词用时，有“然而，尽管（in spite of this）”的含义。它不能像but一样直接连接两个分句，而必须另起新句，并用逗号分开。however可放在句首，也可以插在句子中间。徐达山、王福祯在《英语惯用法大词典》中写道：however作转折连词时，意义与并列连词but相近，只是语气稍弱些。它是起对照、对比或反衬前后两个句子的作用，只能在意义上贯通两个句子，而不能像并列连词but那样在形式上起串联作用。请注意观察下列例句中however的位置、标点符号的使用和第二分句句首首字母的大小写。
Tom was not there(,)but his brother was.
(误)He would like to go.But he can"t.
It"s raining hard.However,I think we should go out.
He hasn"t arrived.He may,however,came later.
He said that it was so;he was mistaken,however.
再如：
Later,however,he decided to go.后来，他们就决定去了。（《牛津现代高级英汉双解词典》）
He was mistaken,however.可是他错了。（同上）
