狀語(yǔ)從句,復(fù)習(xí)重點(diǎn),1. 狀語(yǔ)從句的基本用法。 2. 引導(dǎo)狀語(yǔ)從句的常見(jiàn)連詞。,一、狀語(yǔ)從句的類型及連詞,基礎(chǔ)知識(shí),二、狀語(yǔ)從句中的引導(dǎo)詞 1. while while引導(dǎo)時(shí)間狀語(yǔ)從句時(shí)，從句的謂語(yǔ)必須是延續(xù)性動(dòng)詞（如stay, wait, live等），而不能是非延續(xù)性動(dòng)詞。如： Please don’t talk so loud while others are working. while引導(dǎo)讓步狀語(yǔ)從句時(shí)，相當(dāng)于although / though / as，但while / although引導(dǎo)的讓步狀語(yǔ)從句不用倒裝語(yǔ)序，though引導(dǎo)的讓步狀語(yǔ)從句可以倒裝也可以不倒裝，而as引導(dǎo)的讓步狀語(yǔ)從句則必須倒裝。如：,While / Although / Though the bride is happy, she will feel homesick at the beginning. Happy as the bride is, she will feel homesick at the beginning. 2. until和till until和till都表示“直到”，?？苫Q，但till一般不用于句首，也不用于強(qiáng)調(diào)句中。 until / till從句與肯定的主句連用時(shí)，主句的謂語(yǔ)必須是延續(xù)性動(dòng)詞，表示主句的動(dòng)作一直持續(xù)到until / till所表示的時(shí)間為止。如：,You may stay here until the rain stops. Mr. Bush remained there till his brother arrived. until / till從句與否定的主句連用時(shí)，主句的謂語(yǔ)是非延續(xù)性動(dòng)詞，表示“直到……才”，即主句的動(dòng)作到until / till所表示的時(shí)間才開(kāi)始。如： David won’t go to bed until / till his wife returns. Leo didn’t come until he had gone over his lesson. not until位于句首時(shí)，主句須用倒裝語(yǔ)序。如： Not until I began to work did I realize how much time I had wasted.,not until結(jié)構(gòu)可用于強(qiáng)調(diào)句中。如： It was not until she came to see us that we knew her mother was ill in bed. 3. when when引導(dǎo)時(shí)間狀語(yǔ)從句時(shí)，從句的動(dòng)作既可與主句的動(dòng)作同時(shí)發(fā)生，也可先后發(fā)生。如： When we were at school, we went to the library every day. When the meal was finished, Rachel washed up.,when可以引導(dǎo)條件狀語(yǔ)從句，意為“如果”。如： How can we explain it to you when you won’t listen? when可以作并列連詞，意為“正在那時(shí)，突然”，此時(shí)所引導(dǎo)的從句只能放在主句之后。如： We were swimming in the lake when suddenly the storm started.,4. as as可以引導(dǎo)時(shí)間狀語(yǔ)從句，其動(dòng)作是延續(xù)性的，表示“當(dāng)……時(shí)，隨著”。 The atmosphere gets thinner and thinner as the height increases. as可以引導(dǎo)原因狀語(yǔ)從句，一般放在句首，表示十分明顯的原因。如： As it is raining, we shall not go camping.,as可以引導(dǎo)讓步狀語(yǔ)從句, 通常用倒裝結(jié)構(gòu)。具體情況如下： 形容詞或副詞+ as +主語(yǔ)+系動(dòng)詞be或?qū)嵙x動(dòng)詞。 如: Much as I like it, I won’t buy. 名詞+ as +主語(yǔ)+系動(dòng)詞（句首的名詞前多不帶冠詞）。如： Child as he is, he knows a lot. 實(shí)義動(dòng)詞+ as +主語(yǔ)+助動(dòng)詞（如果沒(méi)有助動(dòng)詞, 則要加上do, does或did）。如： Try as he would, he couldn’t lift the heavy box.,5. no sooner . than ., hardly / scarcely . when . no sooner . than .和hardly / scarcely . when .引導(dǎo)的從句表示“一……就……，剛……就……”的含義。主句中的動(dòng)詞一般用過(guò)去完成時(shí), 從句用一般過(guò)去時(shí)。no sooner, hardly位于句首時(shí), 主句的主謂語(yǔ)要部分倒裝。如： The words had no sooner been spoken than he realized that he should have remained silent.,I had hardly got home when it began to rain. No sooner had we got to the station than the train left. Hardly had we begun when we were told to stop.,6. 由“疑問(wèn)詞-ever”構(gòu)成的復(fù)合詞與“no matter + 疑問(wèn)詞” 由“疑問(wèn)詞-ever”構(gòu)成的復(fù)合詞可以引導(dǎo)讓步狀語(yǔ)從句。此時(shí)以-ever結(jié)尾的復(fù)合詞在口語(yǔ)中可由“no matter +疑問(wèn)詞”代替。如： I’ve told you that I’m going to buy that pen, however much it costs. = ., no matter how much it costs. Don’t trust him, whatever he says. = ., no matter what he says.,常見(jiàn)考點(diǎn),在含狀語(yǔ)從句的復(fù)合句中，主、從句通常根據(jù)實(shí)際時(shí)間關(guān)系來(lái)確定動(dòng)詞的時(shí)態(tài)，但有一點(diǎn)需要注意：在時(shí)間狀語(yǔ)從句、條件狀語(yǔ)從句或由“疑問(wèn)詞-ever”、“no matter +疑問(wèn)詞”等引導(dǎo)的讓步狀語(yǔ)從句中，可以用一般現(xiàn)在時(shí)表將來(lái)。下面就狀語(yǔ)從句考點(diǎn)進(jìn)行歸納總結(jié)。,一、時(shí)間狀語(yǔ)從句 【考例】 It was the middle of the night _____ my father woke me up and told me to watch the football game.
