區(qū)分would與used to的差別
Would與used to都可用來表示過去經(jīng)常性或習(xí)慣性的動(dòng)作，常常可以換用。接下來，小編給大家準(zhǔn)備了區(qū)分would與used to的差別,歡迎大家參考與借鑒。
區(qū)分would與used to的差別
(1)When we were boys we used1 to/would go swimming every summer.
小時(shí)候，每到夏天我們都要去游泳。
(2)He used to/would spend every penny2 he earned on books.
過去，他通常把掙來的錢全花在買書上。
Would與used to都不能用來表示動(dòng)作發(fā)生的具體頻度或具體的一段時(shí)間。例如，不能說：
(3)I would/used to go to France six times.
(4)He used to live in Africa for twenty years.
上兩句應(yīng)改成：
(5)I went to France six times. 我去過法國(guó)6次。
(6)He lived in Africa for twenty years. 他在非洲住過20年。
Would與used to的區(qū)別主要有以下幾點(diǎn)：
a. Used to可指過去的狀態(tài)或情況，would則不能。如：
(7)School children used to know the story of how Abraham Lincoln walked five miles to return a penny he'd overcharged a customer.(不能用would)
過去，學(xué)校的孩子們都知道亞伯拉罕·林肯怎樣步行5英里退還多收顧客1便士的故事。
(8)Yet，he cannot but remember China as it used to be.然而，他不會(huì)不記得舊日的中國(guó)(不能用would)。
b. Would表示反復(fù)發(fā)生的動(dòng)作。如果某一動(dòng)作沒有反復(fù)性，就不能用 would，只能用 used to。例如：
(9) And from that day on， as soon as the table was cleared and the dishes were gone. Mother would disappear3 into her sewing4 room to practice.
從那天起，只要碗盤撤掉、飯桌一清理干凈，媽媽就馬上躲進(jìn)做針線活的房間練習(xí)起來。(具有反復(fù)性)
(10)I used to live in Beijing. 我過去住在北京。(沒有反復(fù)性)
c. Used to表示過去經(jīng)常性或習(xí)慣性的動(dòng)作或狀態(tài)現(xiàn)在已經(jīng)結(jié)束，would則表示有可能再發(fā)生。如：
(11)People used to believe that the earth was flat.
過去，人們總以為地球是扁平的。(現(xiàn)在已不再這樣認(rèn)為)
(12)He would go to the park as soon as he was free.
過去，他一有空就去公園。(現(xiàn)在有可能再去)
注意：used to的否定式和疑問句:
(13)過去我不喜歡歌劇。
I used not to like opera.
I usedn't to like opera.
I didn't use to like opera.
(14)過去你喜歡歌劇嗎?
used you to like opera?
Did you use to like opera?
(15)Didn't you use to like opera? 你過去不喜歡歌劇嗎?
(16)You used to like opera, didn't you? 你過去喜歡歌劇，是嗎?
(17)There used to be a church here， usedn't there? 過去這里有座教堂，是不是?
擴(kuò)展：小議but的用法
在英語(yǔ)中，but除了最常用的表示轉(zhuǎn)折關(guān)系外還有以下幾種常見用法：
一、but用法連詞，表示讓步關(guān)系，意思是“除非，要不是”，常與that一起構(gòu)成but that, 相當(dāng)于"if...not"。 例如：I would1 have failed2 but that your helped me.要不是你們幫助我，我就會(huì)失敗。
二、but用作連詞，放在否定詞或疑問詞之后，作從屬關(guān)系，表示否定意義，可相當(dāng)于that not. 例如： Never a month passed but she writes to her parents. 她沒有一個(gè)月不給她雙親寫信。
三、but用于否定詞加doubt,question,deny等到之后，沒有實(shí)在意義，只相當(dāng)于關(guān)系連詞that. 例如： There"s no doubt3 but he is a thief4.毫無疑問，他是一個(gè)賊。
四、but用作介詞，表示“除了”意義，相當(dāng)于besides,except.例如：No one knows him but she. 除了她，沒有人認(rèn)識(shí)他。
五、but用作副詞，相當(dāng)于only, 常譯為“只不過，僅僅”。例如：He finished5 his homework but ten minutes ago.他十分鐘前剛完成作業(yè)。
六、buy用作代詞，表示從屬關(guān)系，在否定句中常相當(dāng)于who/that not.例如：There is no one but likes to help him. 大家都愿幫他。
