but和however的区别
- but和however的区别
- 1. however作副词用时，表示“然而；但是”，可以位于句首、句中和句末；位于句首时，要用逗号与句子其它部分隔开；位于句中时，其前后都要用逗号；位于句末时其前用逗号分开。 例如: She felt ill. She went to work, however, and tried to concentrate. 她病了。然而她照旧去上班，并且尽力集中精神工作。 His first response was to say no. Later, however, he changed his mind. 他最初的反应是不同意，可是后来他改变了主意。 2. however与but 两者都做“但是，然而”讲，而且都引出并列句。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： I thought those figures were correct. However, I have recently heard they were not. 我原以为那些数字正确无误，不过我最近听说并不正确。 3. however的其它用法： however可以作连词(conj.)，表示“无论以何种方式，不管怎样”，引导让步状语从句。例如： You can travel however you like.你可以随心所欲地去旅行。 However I approached the problem, I couldn’t find a solution. 这一问题我不管怎样都无法解决。
