一、考点 however 分析
however是高考英语中一个十分重要的考点，近几年来每年的各省考题均有所涉及。请看两道典型高考真题：
1. You should try to get a good night’s sleep _____ much work you have to do.
A. however B. no matter C. although D. whatever
【分析】答案选A。however作连接副词时，与no matter how相当，后接形容词或副词，意为“无论……”“不管……”。句意是：不管你有多少工作要做，你都应该好好休息一个晚上。
2. He tried his best to solve the problem, _____ difficult it was.
A. however B. no matter C. whatever D. although
【分析】答案选A。因difficult是形容词，修饰形容词要用连接副词however(无论如何，不管多么)，引导一个让步状语从句。
二、however用法详解
不管however以何种形式出现在高考题中，它都不外乎以下两种用法。
1. 用作副词
(1) 表示让步：意为“无论如何”“不管怎样”，用来修饰形容词或副词，其词序为：however+形容词或副词+主语+谓语。这样用的however其实具有连词的功能，用以引导让步状语从句。如：
Phone me when you arrive, however late it is. 你到达之后就给我打电话，不论多么晚也要打。
However much he eats, he never gets fat. 不管他吃多少，他永远吃不胖。
However cold it is, he always goes swimming. 不管天有多冷，他都去游泳。
You won’t move the stone, however strong you are. 不管你力气有多大，也休想搬动那块石头。
However far it is, l intend to drive there tonight 不管有多远，我今晚也要开车到那儿去。
用于此用法时，请注意以下几点：
①此用法属however所有用法中最重要的考点，同学们务请引起高度重视。
②这样用的 however 与 no matter how 大致同义。如：
People always want more, however [no matter how] rich they are. 人总是富了还想再富。
However [No matter how] hard I worked, she was never satisfied. 无论我多么努力地工作，她从来没满意过。
③有时从句谓语可用情态动词。如：
Don’t laugh, however funny it may be. 无论多么有趣也不要笑。
I’ll try to finish it in time, however hard it may be. 无论多么难，我也要按时完成。
④“however+形容词或副词+主语+谓语”有时可以有所省略。如：
I refuse, however favorable the conditions. 不管条件如何有利，我都不干。(conditions后省去了are)
I’d rather have a room of my own, however small (it is), than share a room. 无论房间多么小，我宁愿一个人住一间，而不愿意与别人合住一个房间。
A grammar rule, however true (it is), is useless unless it can be understood. 一条语法规则，不管如何正确，除非能懂，否则毫无用处。
(2) 表示转折：尤其用于谈及一个既成事实时，表示转折，其意为“可是”“仍然”等。可放在句首、句中或句末，通常用逗号与句子其他成分隔开。如：
My father, however, did not agree. 但是，我父亲不同意。
My room is small; however, it’s comfortable. 我的房间很小，但却很舒服。
He said that it was so; he was mistaken, however. 他说情况如此，可是他错了。
注：however不能像 but(但是)那样直接连接两个句子(注意正句中的标点符号)。如：
我们都已尽了最大的努力，不过我们还是输了。
误：We all tried our best, however we lost the game.
正：We all tried our best, but we lost the game.
正：We all tried our best; however, we lost the game.
正：We all tried our best. However, we lost the game.
