初中英語狀語從句講解及練習(xí)

1、初中英語狀語從句用來修飾主句中的動詞，副詞和形容詞的從句叫狀語從句。根據(jù)其含義狀語從句可分為時間狀語從句，地點狀語從句，條件狀語從句， 原因狀語從句，結(jié)果狀語從句，比較狀語從句，目的狀語從句，讓步狀語從句。1. 時間狀語從句(1)時間狀語從句常用when, as, while, before, after, since, till, until, as soon as等連詞來引導(dǎo)。例如： it was raining hard when got to school yesterday. (2)在時間狀語從句里，通常不用將來時態(tài)，用現(xiàn)在時態(tài)表示將來的動作或狀態(tài)。例如：ill ring you u

2、p as soon as i get to new york. (3)在帶有till或until引導(dǎo)的時間狀語從句的主從復(fù)合句里，如果主句用肯定式，其含義是“一直到時”，謂語動詞只能用延續(xù)性動詞。如果主句用否定式，其含義是“直到才”, “在以前不”, 謂語動詞可用瞬間動詞。例如：the young man read till the light went out.2. 條件狀語從句(1)條件狀語從句通常由if, unless引導(dǎo)。例如：what shall we do if it snows tomorrow? (2)在條件狀語從句里，謂語動詞通常用現(xiàn)在時態(tài)表示將來的動作或狀態(tài)。例如：ill

3、help you with your english if am free tomorrow. (3)“祈使句 + and (or)+ 陳述句” 在意思上相當(dāng)于一個帶有條件狀語從句的復(fù)合句。例如： hurry up, or youll be late. =if you dont hurry up, youll be late.3. 原因狀語從句(1)原因狀語從句通常由because, since, as引導(dǎo)。例如：he didnt come to school because he was ill. (2)because表示直接原因，語氣最強。because引導(dǎo)的原因狀語從句多放在主句之后?；?/p>

4、答由why提出的問題，只能用because。as和since語氣較弱，一般用來表示明顯的原因。由as和since引導(dǎo)的原因狀語從居多放在句首。例如：-why arent going there? -because i dont want to. (3)because和so不能同用在一個句子里。4. 結(jié)果狀語從句(1)結(jié)果狀語從句由sothat, suchthat, so that引導(dǎo)。例如：he is so poor that he cant buy a bike for his son. (2)sothat語such.that可以互換。在由so.that引導(dǎo)的結(jié)果狀語從句中，so是副詞，與形

5、容詞連用。其結(jié)構(gòu)是: “.so + 形容詞（副詞）+ that + 從句”。例如：he was so glad that he couldnt say a word.在由suchthat引導(dǎo)的結(jié)果狀語從句中，such是形容詞，它修飾的可以是單數(shù)或復(fù)數(shù)可數(shù)名詞，也可以是不可數(shù)名詞；名詞前面可以帶形容詞，也可不帶。如果是單數(shù)可數(shù)名詞，前面需加不定冠詞a或an。例如：it was such a hot day that nobody wanted to do anything. 有時上述兩種結(jié)構(gòu)是可以互換的。例如：it was such a wonderful film that all of us

6、 wanted to see it again.=the film was so wonderful that all of us wanted to see it again. (3)如果名詞前由many, much, little, few等詞修飾時，只能用so, 不用such。例如：soon there were so many deer that they ate up all the wild roses.5. 比較狀語從句比較狀語從句通常由asas, 比較級 + than等連詞引導(dǎo)。例如：tom runs faster than john does.6. 目的狀語從句(1)目的狀語

7、從句通常由 so that, in order that引導(dǎo)。例如：we started early so that we could catch the first train. (2)so that既可引導(dǎo)目的狀語從句，又可引導(dǎo)結(jié)果狀語從句。區(qū)別這兩種從句的辦法有兩個：1)目的狀語從句里往往帶有情態(tài)動詞can, could, may, might等。2)從意思上看，目的狀語從句往往表示的目的很明確。例如：speak clearly so that they may understand you. (目的狀語從句)jack is badly ill so that he has to res

8、t. (結(jié)果狀語從句)7. 讓步狀語從句(1)讓步狀語從句通常由although, though等連詞引導(dǎo)。例如：though he is young, he knows a lot. although i am tired, i must go on working.(2)although(though)不能用在同一個句子中。例如：我們不能說：though it was raining hard, but he still went out. 應(yīng)該說：though it was raining hard, he still went out.或it was raining hard, but

9、 he still went out.8. 地點狀語從句 地點狀語從句常常由where來引導(dǎo)。例如： go where you like. 【實例解析】1.
