狀語(yǔ)從句的分類
1. 時(shí)間狀語(yǔ)從句
(1)時(shí)間狀語(yǔ)從句常用when, as, while, before, after, since, till, until, as soon as等連詞來(lái)引導(dǎo)。
例:It was raining hard when got to school yesterday.
(2)在時(shí)間狀語(yǔ)從句里,通常不用將來(lái)時(shí)態(tài),用現(xiàn)在時(shí)態(tài)表示將來(lái)的動(dòng)作或狀態(tài)。
例:I'll ring you up as soon as I get to New York.
3)在帶有till或until引導(dǎo)的時(shí)間狀語(yǔ)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(shí)”,謂語(yǔ)動(dòng)詞只能用延續(xù)性動(dòng)詞。如果主句用否定式,其含義是“直到……才……”, “在……以前不……”, 謂語(yǔ)動(dòng)詞可用瞬間動(dòng)詞。
例:The young man read till the light went out.
2. 條件狀語(yǔ)從句
(1)條件狀語(yǔ)從句通常由if, unless引導(dǎo)。
例:What shall we do if it snows tomorrow?
(2)在條件狀語(yǔ)從句里,謂語(yǔ)動(dòng)詞通常用現(xiàn)在時(shí)態(tài)表示將來(lái)的動(dòng)作或狀態(tài)。
例:I'll help you with your English if I am free tomorrow.
(3)“祈使句 + and (or)+ 陳述句” 在意思上相當(dāng)于一個(gè)帶有條件狀語(yǔ)從句的復(fù)合句。
例:Hurry up, or you'll be late.
=If you don't hurry up, you'll be late.
3. 原因狀語(yǔ)從句
(1)原因狀語(yǔ)從句通常由because, since, as引導(dǎo)。
例:He didn't come to school because he was ill.
(2)because表示直接原因,語(yǔ)氣最強(qiáng)。Because引導(dǎo)的原因狀語(yǔ)從句多放在主句之后?;卮鹩蓋hy提出的問(wèn)題,只能用because。
As和since語(yǔ)氣較弱,一般用來(lái)表示明顯的原因。由as和since引導(dǎo)的原因狀語(yǔ)從居多放在句首。
例:------Why aren't going there?
------Because I don't want to.
As he has no car, he can't get there easily.
Since we have no money, we can't buy it.
(3)because和so不能同用在一個(gè)句子里。
4. 結(jié)果狀語(yǔ)從句
(1)結(jié)果狀語(yǔ)從句由so…that, such…that, so that引導(dǎo)。例:He is so poor that he can't buy a bike for his son.
(2)so…that語(yǔ)such...that可以互換。例如:
在由so...that引導(dǎo)的結(jié)果狀語(yǔ)從句中,so是副詞,與形容詞連用。其結(jié)構(gòu)是: “...so + 形容詞(副詞)+ that + 從句”。
例:He was so glad that he couldn't say a word.
(3)如果名詞前由many, much, little, few等詞修飾時(shí),只能用so, 不用such。
例:Soon there were so many deer that they ate up all the wild roses.

比較狀語(yǔ)從句通常由as… as, 比較級(jí) + than…等連詞引導(dǎo)。
例:Tom runs faster than John does.

目的狀語(yǔ)從句通常由 so that, in order that引導(dǎo)。
例:We started early so that we could catch the first train.
7. 讓步狀語(yǔ)從句
(1)讓步狀語(yǔ)從句通常由although, though等連詞引導(dǎo)。
例:Though he is young, he knows a lot.
(2)although(though)和but不能用在同一個(gè)句子中。
例:我們不能說(shuō):Though it was raining hard, but he still went out.
