英語(yǔ)有100萬(wàn)個(gè)單詞,而連接詞卻只有70個(gè)左右,它們總是非常高頻率的出現(xiàn)在各類文章、對(duì)話、電郵等英語(yǔ)實(shí)際溝通中。我們常見(jiàn)的表示轉(zhuǎn)折的過(guò)渡詞有:but,still,yet,however,nevertheless,nonetheless,on?the?contrary,in?spite?of,even?though等。
下面我們先來(lái)看一下這五個(gè)常用的表示轉(zhuǎn)折的連詞都是誰(shuí):
but
(屬并列連詞表轉(zhuǎn)折,上下分句所述情況相反,用在句中,后不加逗號(hào))但是,可是
?Life is limited but there is no limit to learning.
while
(屬并列連詞表對(duì)比,但程度不及st詛l強(qiáng)烈)雖然,盡管,而 
she is very diligent,while he is very lazy. 
yet
(屬副詞作并列連詞用,語(yǔ)氣比but強(qiáng)烈,可與與and,but連用)而,然而,可是 
He said he would be late,yet he arrived on time.
however
(屬副詞兼作并列連詞用,表轉(zhuǎn)折比but稍松弛,可位于句中首、尾〕用逗號(hào)分開)可是,然而
It's raining hard, however,I think we should go out. 
still
(屬副詞作連詞用)盡管如此,但仍然如故(常用于后一分句,可以跟逗號(hào))仍然
I didn't win the game still it's been a good experience.
though
(作副詞用,一般用在句末)(口語(yǔ))可是,不過(guò),然而
It is hard work,I enjoy it though.
 
但在實(shí)際語(yǔ)言應(yīng)用中這些詞區(qū)別甚微,有時(shí)可互為轉(zhuǎn)。
