Explanation.a. but and howeverbut 作為并列連詞，在意義上起轉(zhuǎn)折作用。 but 前后的兩個句子或短語在意義上形成鮮明對照。 but 用來連接兩個分句或兩個較長的短語時， but 前面一般要加逗號。例如：（ 1 ） He is old but strong. 他年紀(jì)雖大卻很強(qiáng)壯。（ 2 ） Learning the guitar isn't difficult, but you will have to practise. 學(xué)彈吉他并不難，但是你得練習(xí)。（ 3 ） He tried， but could not do it. 他試過，但是干不了。however 意為“可是，然而，盡管”，較 but 的意味弱，通常用作連接性狀語。其位置可以在句首，句末或插入句中。當(dāng)其被用來對照兩個分句時，中間需要有一個逗號；當(dāng)它被用作句子的插入語時，則前后應(yīng)各有一個逗號。例如：（ 4 ） However，we need not do that now. 可是，我們現(xiàn)在不需要做那個。（ 5 ） He said it was so；he was mistaken，however. 他說是那樣的，然而他卻弄錯了。（ 6 ） His friends，however，had other ideas. 然而他的朋友們卻另有見解。注： however 也可用作連接副詞，意為“不論怎樣”，用來引導(dǎo)讓步狀語從句。例如：However we may do it，it will be a difficult job. 無論雪下得多大，我們都必須回去。b. although and whileWhile表示兩個事實(shí)之間的轉(zhuǎn)折對比，although可以用but改寫成另一種句子while 用作連詞時，連接兩個并列句子，表示“對比”關(guān)系。例如：He went out for a walk， while I stayed at home.（他出去散步了，而我卻呆在家里。）I like singing while she likes dancing.（我喜歡唱歌，而她喜歡跳舞。）You like sports， while I prefer music.（你喜歡體育，而我更喜歡音樂。）although引導(dǎo)的從句放在主句前后均可，有時還可放在句中。Although many difficulties are still ahead, we are determined to make greater achievements.盡管在前面的道路上還有許多困難，但是，我們決心要取得更大的成就。He often helps me with my English although he is quite busy.盡管他相當(dāng)忙，但是還常常幫我學(xué)英語。although引導(dǎo)的從句不能與but, however連用，但可與yet, still連用。不能說：Although he was old, but he worked hard. 應(yīng)把but去掉。當(dāng)然，保留but而去Although也可。c.
