初中英語(yǔ)語(yǔ)法大全：狀語(yǔ)從句

　　狀語(yǔ)從句

　　在復(fù)合句中，修飾主句中的動(dòng)詞、形容詞或副詞等的從句叫狀語(yǔ)從句。狀語(yǔ)從句根據(jù)它表達(dá)的意思可分為時(shí)間、地點(diǎn)、原因、目的、結(jié)果、讓步、比較(或方式)和條件等類。

　　1.時(shí)間狀語(yǔ)從句

　　引導(dǎo)連詞有when，while，till，not…until，since，after ,before ,as soon as

　　The bus won’t start until everybody gets on.

　　公共汽車直到每人都上車為止，才開(kāi)動(dòng)。

　　When he knocked at the door I was cooking.

　　當(dāng)他敲門時(shí)，我正在煮飯。

　　Last night before he came back home, his wife had already cooked dinner and waited for 2 hours.

　　昨天晚上在他回到家之前，他的妻子已經(jīng)做好晚飯足足等了他兩小時(shí)之久。

　　After I went to church, I went shopping.

　　2. 地點(diǎn)狀語(yǔ)從句

　　地點(diǎn)狀語(yǔ)從句通常由where, wherever 引導(dǎo)。

　　Where there is a will, there is a way. 哪里有志向，哪里就有出路。有志者事竟成。

　　Where there is a life, there is a hope. 哪里有生命，哪里就有希望。 留得青山在，不怕沒(méi)柴燒。

　　Wherever you go, whatever you do, I will be right here waiting for you.

　　不管你去哪里，不管你做什么，我都會(huì)在此守侯你。

　　3.原因狀語(yǔ)從句

　　引導(dǎo)連詞有because，as, since。

　　他沒(méi)有看那部電影，因?yàn)樗呀?jīng)看過(guò)了。

　　They couldn’t get on the train，for it was too crowed.

　　比較：because, since, as和for

　　1)　because語(yǔ)勢(shì)最強(qiáng)，用來(lái)說(shuō)明人所不知的原因，回答why提出的問(wèn)題。當(dāng)原因是顯而易見(jiàn)的或已為人們所知，就用as或 since。

　　I didn't go, because I was afraid.

　　Since /As the weather is so bad, we have to delay our journey.

　　2)　由because引導(dǎo)的從句如果放在句末，且前面有逗 號(hào)，則可以用for來(lái)代替。但如果不是說(shuō)明直接原因，而是多種情況加以推斷，就只能用for。

　　He is absent today, because / for he is ill.

　　He must be ill, for he is absent today.

　　注意

　　because不能和so 連用。

　　4. 目的狀語(yǔ)從句

　　引導(dǎo)連詞有 that， so that…，in order that。

　　So that …——以便/以致……

　　例如：(1)They studied hard so that they could pass the exam.

　　(2)They started early so that they caught the early bus.

　　注意點(diǎn)：

　　在例句(1)中,是引導(dǎo)目的狀語(yǔ);在例句(2)中，是引導(dǎo)結(jié)果狀語(yǔ)。一般來(lái)講，從句中含有情態(tài)動(dòng)詞的，為目的狀語(yǔ)。無(wú)情態(tài)動(dòng)詞的，為結(jié)果狀語(yǔ)。

　　such+名詞性詞組+that…

　　So+形容詞/副詞+that…——如此……以致……

　　例如：(1)She is such a good teacher that we all love her.

　　(2)It was such a hot day that they didn’t go out for a walk as usual.

　　注意點(diǎn)：

　　1.such+a+形容詞+名詞+that…，可以改寫成：so+形容詞+a+名詞+that…，例句(1)可以改寫成：She is so good a teacher that we all love her.

　　2.在such+形容詞+名詞復(fù)數(shù)或不可數(shù)名詞+that…結(jié)構(gòu)中，形容詞如果是many/few或much/little時(shí)，用so不用such，即：so+many/few+可數(shù)名詞復(fù)數(shù)+that…，so+much/little+不可數(shù)名詞+that…

　　(1)There are so many people in the room that I can’t get in.

　　1) 時(shí)間狀語(yǔ)從句和條件狀語(yǔ)從句中的時(shí)態(tài)與主句的搭配：(俗稱：主將從現(xiàn))
