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. 参考资料:http://answer./8522752/Question/7276.html |
