However的用法1.李秀芹主编《大学英语关联词精编》(天津大学出版社1999年6月第1版)P75: however1.引导让步状语从句 in whatever way or degree 无论如何，不管怎样1）however+形容词或副词 ，意为“不管怎样”，多用于书面语。例如：However far it is, I tend to drive there tonight.不管有多远，我今晚也要开车到那儿去。However rich some people are (No matter how rich some people are), they always seem anxious to make more money. 有些人不管多么富裕，他们总是渴望赚更多的钱。However hard I try, I cannot understand this question.尽管我费了好大的劲，这个问题我仍然不能理解。However cold it is, she always goes swimming.无论天气多么冷，她总是去游泳。2）however+形容词或副词+主语+ may 是是较委婉表示让步的通用形式，有事可以省略“may be”。例如：However hard he may try, he will not attain his object. 不论他怎样努力，也不会达到他的目的。However much you may split up life, it is always a united whole. 无论你这样分裂生活，它始终是一个统一的整体。However bad the weather may be, we shall have to plant the rice seedlings.不管天气怎样不好, 我们也得把稻秧插下去。However imperfect our machine (may be), they can help us amazingly. 我们的机器无论怎么不完善，也能对我们很有用。2.引导方式状语从句例如：Arrange your time however you like. 你爱怎么安排时间就怎么安排时间吧。In one’s own home one can act however one wishes. 在自己家里，一个人可以随心所欲。He can go however he likes. 他爱怎么去就怎么去好了。2.孟德杰《英语关连词词典》（中国国际广播出版社）P43：howeverI.【从连】]【引：让步】不管这样，无论如何However hard it may be, do your best. 不管这事怎么难，还是尽你的全力去做吧。He resolved to pace himself and be [very] careful. He would make it out, however long it took. 他决定匀速前进，一切谨慎小心。不管时间多久，他一定能成功。All through the war, Clay had read all Lorette’s letters aloud to X, however intimate they were…在整个战争期间，克雷都把洛莱特的来信大声读给X听，也不管这信多么亲昵………however desirous he might be to see the person in question, he was nevertheless relieved by his absence. ……不管他多么想见到此人，但对他没来还是感到松了一口气。III.【从连】【引：方式】不管用什么方式He can go however he likes. 他爱怎么去就怎么去好了。Arrange your time however you like. 你爱怎么安排时间就怎么安排时间吧。In one’s own home one can act however one wishes. 在自己家里，一个人可以随心所欲。以上可可以看出： however 引导方式状语从句，其后不接形容词或副词；引导让步状语从句，其后接形容词或副词。
