【語(yǔ)法——狀語(yǔ)從句】，學(xué)習(xí)英語(yǔ)的話英語(yǔ)可是很重要的哦，大家趕緊；來(lái)5068頻道看看淺陌帶給大家的語(yǔ)法總結(jié)吧。

　　狀語(yǔ)從句是句子的狀語(yǔ)由一個(gè)從句充當(dāng)，來(lái)修飾主句中的動(dòng)詞，形容詞或副詞等。狀語(yǔ)從句都由從屬連詞引導(dǎo)，與主句連接，放在句末時(shí)，一般不在前面加逗號(hào)。

　　狀語(yǔ)從句根據(jù)它表示的意思可分為時(shí)間，原因，條件，比較，結(jié)果，目的等類。下面我們揀重點(diǎn)的一個(gè)一個(gè)來(lái)分析。

　　時(shí)間狀語(yǔ)從句：是由when, as, while, after, before, since, until, as soon as 等從屬連詞引導(dǎo)的狀語(yǔ)從句。時(shí)間狀語(yǔ)從句中的謂語(yǔ)動(dòng)詞不能用一般將來(lái)時(shí)，只能用一般現(xiàn)在時(shí)表示將來(lái)發(fā)生的動(dòng)作或存在的狀態(tài)。 如:I will call you as soon as I arrive there.

　　原因狀語(yǔ)從句： because, since, as和for都表示原因。常常令我們不知該用哪個(gè)好。我們來(lái)比較一下。because語(yǔ)勢(shì)最強(qiáng)，回答why提出的問(wèn)題，用來(lái)說(shuō)明人所不知的原因。當(dāng)能夠很明顯的看出原因或人們已知原因，就用as或since。如：I don't like that coat,because the color looks terrible. 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。如：He is not here, because / for his mother is ill.

　　目的狀語(yǔ)從句：表示目的狀語(yǔ)的從句可以由in order that, so that,等詞引導(dǎo)。如：You must raise your voice so that/in order that everybody can hear you clearly.

　　結(jié)果狀語(yǔ)從句：結(jié)果狀語(yǔ)從句常由so...that 或 such...that引導(dǎo)，要掌握和區(qū)分這兩個(gè)句型，首先要了解so和such后面分別跟什么詞。such是形容詞，修飾名詞或名詞詞組，so是副詞,只能修飾形容詞或副詞。so 還可與表示數(shù)量的形容詞many, few, much, little連用，形成固定搭配。如：The box is so heavy that I can't carry it.

　　讓步狀語(yǔ)從句：是由though, although 引導(dǎo)的狀語(yǔ)從句。though, although 和 but不能同時(shí)使用。

　　Although it rained, they had a good time.
