英語連詞解析 | but 與 however的用法區(qū)別
連詞是一種虛詞,用于連接單詞、短語、從句或句子,在句子中不單獨(dú)用作句子成分。連詞按其性質(zhì)可分為并列連詞和從屬連詞。并列連詞用于連接并列的單詞、短語、從句或句子,如and, but, or, for等;從屬連詞主要引出名詞性從句(主語從句、賓語從句、表語從句等)和狀語從句(時間狀語從句、條件狀語從句、目的狀語從句等),引出名詞性從句的連詞如that, whether等,引出狀語從句的連詞如when, because, since, if 等。
but 與 however的用法區(qū)別
兩者均可表示轉(zhuǎn)折或?qū)Ρ?,意為“但是”、“可是”、“然而”等,但有區(qū)別:
1. 表示轉(zhuǎn)折時,but 是連詞。如:
He is young but very experienced. 他雖年輕,但經(jīng)驗(yàn)很豐富。
He has three daughters but no sons. 他有3 個女兒,但沒有兒子。
He likes sports, but his wife likes music. 他喜歡運(yùn)動,而他妻子則喜歡音樂。
2. however 表示“然而”、“可是”時,有的詞書認(rèn)為它是連詞,有的詞書認(rèn)為它是副詞。
之所以將其視為副詞,也許是因?yàn)橄裨S多副詞一樣不僅能位于句首,而且能位于句中(注意前后使用逗號),甚至句末(注意其前也用逗號)。如:
Later, however, he changed his mind. 可是他后來改變了主意。
He hasn’t arrived. He may, however, come later. 他還沒有到,不過他等會兒可能會來。
He said that it was so; he was mistaken, however. 他說情況如此,可是他錯了。
注意:以上各例中的 however 不能換成 but,但可用 but 來改寫。如:
He said that it was so, but he was mistaken. 他說情況如此,可他錯了。
3. 當(dāng)連接兩個句子時,其前通常應(yīng)用分號,或另起新句。如:
It’s raining hard; however, I think we should go out. / It’s raining hard. However, I think we should
?go out. 雨下得很大,但我想我們還得出去。
注意:上例中的 however 不能換成 but,但可用 but 來改寫 (注意所用標(biāo)點(diǎn)的變化)。如:
It’s raining hard, but I think we should go out.
