狀語從句的用法如何使用狀語從句

時間: 謝君787 分享

  狀語從句即指在主從復(fù)合句用作狀語的從句。那狀語從句具體要怎么使用呢?以下是由學(xué)習(xí)啦小編整理關(guān)于狀語從句的用法的內(nèi)容,希望大家喜歡!

  狀語從句的用法

  一、概說

  按照其意義,狀語從句可分為時間狀語從句、地點狀語從句、原因狀語從句、目的狀語從句、結(jié)果狀語從句、條件狀語從句、讓步狀語從句等。狀語從句是高中英語學(xué)習(xí)中的一個語法重點,也是歷年高考重點考查的內(nèi)容之一。學(xué)習(xí)狀語從句主要應(yīng)注意引導(dǎo)狀語從句的從屬連詞的用法與區(qū)別,以及從屬連詞在一定的語言環(huán)境中的意義與用法。

  二、時間狀語從句

  1. 引導(dǎo)時間狀語從句的從屬連詞很多,常見的有before, after, when, while, as, since, till, until, as soon as 等。

  2. 表示“當(dāng)…時候”的 while, when, as 的用法區(qū)別是:while從句中的謂語動詞必須是延續(xù)性動詞;表示帶有規(guī)律性的“每當(dāng)”或當(dāng)主、從句謂語動詞的動作發(fā)生有先后時,只能用 when;當(dāng)表示“一邊…一邊…”或“隨著”時,只能用 as。另外,用于此義的 as 所引導(dǎo)的時間狀語從句謂語只能是動作動詞,不能是狀態(tài)動詞。如下面一道高考題的答案是 B 而不能是A:

  “I’m going to the post office.” “_____ you’re there, can you get me some stamps?”

  A. As B. While C. Because D. If

  3. until 在肯定句中通常只連用延續(xù)性動詞,表示相應(yīng)動作結(jié)束的時間;在否定句中通常連用非延續(xù)性動詞,表示相應(yīng)動作開始的時間,意為“直到…才”。如:

  He waited until she was about to leave. 他等著一直到她準(zhǔn)備離開。

  I did not begin to work till he had gone. 他走了后我才開始工作。

  4. 表示“一…就”除用 as soon as 外,還可用 the minute, the second, the instant, immediately, directly, instantly, no sooner…than, hardly…when 等。如:

  I came immediately you called. 你一來電話我就來了。

  Hardly had she arrived when it began to snow. 她剛到就下起雪來了。

  The moment I have finished I'll give you a call. 我一干完就給你打電話。

  5. every time, each time, (the) next time, (the) last time, by the time, the first time, any time 等以 time 結(jié)尾的詞語也可用作連詞,引導(dǎo)時間狀語從句。如:

  Next time you come in, please close the door. 下次你進來,請關(guān)門。

  He didn’t tell me anything the last time I saw him. 上次我見到他時他什么也沒告訴我。

  By the time I got home, she had already gone to bed. 我到家時她已睡覺了。

  三、條件狀語從句

  1. 引導(dǎo)條件狀語從句的從屬連詞主要有 if, unless, as [so] long as等。如:

  Don’t come unless I telephone. 除非我打電話,否則你別來。

  If you watch carefully you will see how to do it. 如果你仔細(xì)瞧你會看出該怎樣做。

  As long as you do your best, we’ll be happy. 只要你盡力,我們就滿意了。

  2. in case 也可引導(dǎo)條件狀語從句,其意為“如果”、“萬一”。如:

  In case I forget, please remind me about it. 如果我忘了,請?zhí)嵝盐摇?/p>

  四、讓步狀語從句

  1. 引導(dǎo)讓步狀語從句的從屬連詞主要有 although, though, however (=no matter how), even if(即使), whether…or(不論…還是)等連詞。如:

  The speech is good, though it could be better. 這次演講不錯,雖然還可以再好一點。

  He went out even though it was raining. 盡管下雨,他還是出去了。

  2. as 也可引導(dǎo)讓步狀語從句,但要將名詞、形容詞或副詞等提到 as 前,若提前的是單數(shù)可數(shù)名詞,要省略 a / an。如:

  Teacher as he is, he can’t know everything. 雖然是老師,他也不可能什么都懂。

  3. 連詞 while 有時也可表示“盡管”、“雖然”,引導(dǎo)讓步狀語從句。如:

  While we don’t agree we continue to be friends. 盡管我們意見不同,我們還是朋友。

  4. whatever, whoever, however, whenever, wherever 等引導(dǎo)讓步狀語從句。如:

  Don’t lose heart whatever you do. 不管你做什么,都不要灰心。

  Whoever you are, you can’t pass this way. 不管你是誰,你都不能從這里通過。

  注:表示“雖然”的 though, although 不可與 but 連用,但可與 yet, still 連用。
