1、用作副詞
(1) 表示讓步：意為“無論如何”“不管怎樣”,用來修飾形容詞或副詞,
其詞序為：however+形容詞或副詞+主語+謂語.這樣用的however其實具有連詞的功能,用以引導(dǎo)讓步狀語從句.如：
however much he eats,he never gets fat.不管他吃多少,他永遠(yuǎn)吃不胖.
用于此用法時,請注意以下幾點：
�、俅擞梅▽賖owever所有用法中最重要的考點,同學(xué)們務(wù)請引起高度重視.
�、谶@樣用的 however 與 no matter how 大致同義.如：
People always want more,however [no matter how] rich they are.人總是富了還想再富.
however [No matter how] hard I worked,she was never satisfied.無論我多么努力地工作,她從來沒滿意過.
�、塾袝r從句謂語可用情態(tài)動詞.如：
Don’t laugh,however funny it may be.無論多么有趣也不要笑.
I’ll try to finish it in time,however hard it may be.無論多么難,我也要按時完成.
④“however＋形容詞或副詞＋主語＋謂語”有時可以有所省略.如：
I refuse,however favorable the conditions.不管條件如何有利,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.無論房間多么小,我寧愿一個人住一間,而不愿意與別人合住一個房間.
A grammar rule,however true (it is),is useless unless it can be understood.一條語法規(guī)則,不管如何正確,除非能懂,否則毫無用處.
(2) 表示轉(zhuǎn)折：尤其用于談及一個既成事實時,表示轉(zhuǎn)折,其意為“可是”“仍然”等.可放在句首、句中或句末,通常用逗號與句子其他成分隔開.如：
My father,however,did not agree.但是,我父親不同意.
My room is small; however,it’s comfortable.我的房間很小,但卻很舒服.
He said that it was so; he was mistaken,however.他說情況如此,可是他錯了.
注：however不能像 but(但是)那樣直接連接兩個句子(注意正句中的標(biāo)點符號).如：
我們都已盡了最大的努力,不過我們還是輸了..
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) 表示驚奇或強調(diào)：相當(dāng)于how ever的用法,其意為“究竟怎樣,到底以什么方式”。
