1.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。however多插在句中,有时也放在句首或句尾,但都应紧跟在进行对比的词或短语之后,用逗号将其与其他词分开。
2.however的内涵更多,用法更灵活,nevertheless使用使用范围较窄。
3.however可作副词,也可作连词。
He can answer the question however hard it is.
不管问题有多难他都能回答。
However did you get here?
你是怎么到这里来的?
He hasn't arrived. He may, however, come later.
他还未到,不过,他可能过一会儿来。
4.nevertheless可作副词,也可作连词。nevertheless指尽管作出完全让步,也不会发生任何影响。
She was very tired, nevertheless she kept on working.
她虽然很疲倦,可仍在继续工作。
He's stupid, but I like him nevertheless.
他是很笨,然而我喜欢他。
