1.用作副词，注意以下用法：(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，用以引导一个让步状语从句。如：Howevermuchheeats,henevergetsfat.不管他吃多少，
(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，用以引导一个让步状语从句。
如：
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。
However far it is, I intend to drive there tonight.
不管有多远，我今晚也要开车到那儿去。
这样用的 however 与 no matter how 大致同义。
如：
No matter how much he eats, he never gets fat.
No matter how cold it is, he always goes swimming.
No matter how far it is, I intend to drive there tonight.
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。
另外，“however+形容词或副词+主语+谓语”有时可以有所省略。
如：
I refuse, however favourable 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。
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。
注意，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.
如：
However did you get here without a car?
没有汽车你究竟是怎样来的呢?

他聋成这个样子，究竟是怎样从事作曲的呢?
2. 用作连词，引导方式状语从句，表示“无论以何种方式”“不管怎样”。
如：
However it may be, I shall take your word.
无论如何，我将会相信你的话。

这张画不论怎么看都显得不对劲。
However you travel, it’ll take you at least two days.
