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.

　　②這樣用的 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”。
