however的用法总结
however表示然而,掌握however的用法对英语学习是很有必要的,下面小编给大家整理了however的用法总结,希望大家喜欢!
用法
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：
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。
(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(www.yygrammar.com)。
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.
(3) 表示惊奇或强调，相当于how ever的用法，其意为“究竟怎样，到底以什么方式”。如：
However did you get here without a car? 没有汽车你究竟是怎样来的呢?
However does he manage to write music when he is so deaf? 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。
The painting looks wrong however you look at it. 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. 无论你怎么个走法，至少要两天时间。
词义辨析
but,however,still,yet,nevertheless,while,whereas
这些连词或副词均含“但是，可是，然而，而”之意。 but口语常用词，语气较强，泛指与前述情况相反。 however表转折关系，语气稍弱于but，连接性也弱一些，因而常作插入语。 still语气强，多用于肯定句或疑问句。指尽管作出让步，采取措施或表示反对，但情况仍然如故，无所改变。 yet常用于否定句，语气比still稍强。指不管作出多大努力或让步，仍达不到预期的结果。 nevertheless指尽管作出完全让步，也不会发生任何影响。 while表对比，一般可与whereas换用，但程度弱一些。 whereas表对比，一般可与while互换。
