【一句話概括】狀語從句的主要語法作用是修飾主句的謂語動(dòng)詞,它跟單個(gè)的副詞不一樣,它一般不修飾其他詞語.
所謂狀語從句,就是句子作狀語,作狀語的從句叫做狀語從句.
分為時(shí)間狀語從句、地點(diǎn)狀語從句、原因狀語從句、目的狀語從句、結(jié)果狀語從句、條件狀語從句、讓步狀語從句、比較狀語從句、方式狀語從句等.
【每種狀語從句舉一個(gè)例子】基本都是修飾主句謂語動(dòng)詞的：
When I was at school,I loved history.我上學(xué)時(shí)喜歡歷史.
You can go anywhere you like.你可以到你想去的任何地方.
He was punished only because he broke the law.他就是因?yàn)檫`犯了法律才受到懲罰的.
I'll speak slowly so that you can understand me.我會(huì)說得慢些,以便你能明白我的意思.
We arrived early in the morning,so (that) we caught the first train.我們在早上到得很早,所以趕上了早班火車.
If you heat water,it will become vapour.如果你給水加熱,它會(huì)變成水蒸氣.
Even though he is poor,she loves him.盡管他很窮,但她還是愛他.
He speaks English as well as you do.他英語說得和你一樣好.
The young man with long hair looks as if he were a girl.這個(gè)留著長發(fā)的小伙子看起來像個(gè)女孩.
我的回答滿意嗎?
（劉老師 您好，雖然我能分辨出是什么種類的狀語從句，我還是理解不了這個(gè)從句和主句的謂語動(dòng)詞時(shí)種怎樣的修飾關(guān)系。好的。我回答你：When I was at school,I loved history.我上學(xué)時(shí)喜歡歷史。----------------------------------------------When I was at school是時(shí)間狀語從句，修飾謂語動(dòng)詞loved，說明：我喜歡歷史是在什么時(shí)間，就是在我上中學(xué)的時(shí)候。 You can go anywhere you like.你可以到你想去的任何地方。---------------------------------------- anywhere you like是地點(diǎn)狀語從句，修飾go，說明你可以去的地方，即：你喜歡的任何地方。 He was punished only because he broke the law.他就是因?yàn)檫`犯了法律才受到懲罰的。--------because he broke the law.是原因狀語從句，修飾was punished，就是說，他為什么被懲罰，或者被懲罰的原因。 I'll speak slowly so that you can understand me.我會(huì)說得慢些，以便你能明白我的意思。-------so that you can understand me.是目的狀語從句，修飾speak，說明speak slowly的目的是為了什么。以此類推。【重要事項(xiàng)】總之，狀語從句就相當(dāng)于一個(gè)副詞。什么叫副詞？副詞就是adverb，什么叫adverb？adverb就是add +verb（加強(qiáng)動(dòng)詞），所以說，副詞或狀語從句主要作用就是修飾動(dòng)詞的。例如：I found my pen yesterday. （昨天）I found my pen when I was walking in the street.（我在大街上走的時(shí)候）【提示】yesterday和when I was walking in the street起一樣的作用，都是時(shí)間狀語，都是說明found的時(shí)間。只是前者是一個(gè)副詞，后者是一個(gè)句子（從句）而已。
