狀語從句是副詞性從句，它在句子中擔任狀語，修飾主句的動詞、形容詞或副詞。根據修飾的方面，狀語從句可以分為以下九種：時間狀語從句、地點狀語從句、原因狀語從句、目的狀語從句、結果狀語從句、條件狀語從句、方式狀語從句、讓步狀語從句和比較狀語從句。還未學習過狀語從句上篇的同學戳此去看哦>>

六、條件狀語從句

1.unless從句的謂語只能用肯定式。unless和if…not同義，unless是書面語，if…not是口語，通常二者可以換用。條件狀語從句中的謂語動詞的時態一般要用現在時或過去時代替一般將來時或過去將來時。從屬連詞為if, unless, as/so long as, in case, so far as。Difficulties are nothing if we are not afraid of them.如果我們不怕困難，困難就算不了什么了。We shall go there tomorrow unless it rains.除非下雨，我們明天就去那里。= We shall go there tomorrow if it doesn’t rain.So/As long as you work hard, you will succeed.只要你努力工作，你就一定能成功。In case I forget, please remind me about it .萬一我忘了，請提醒我一下。So far as I know, the book will be published next month.據我所知，那本書下月出版。

七、方式狀語從句

1.此處as譯為，按照或正如as if或as though的意義和用法基本一樣。從句中可以用現在時表示可能符合事實，也可以用虛擬語氣。Draw a cat as I taught you .按照我教你的畫一只貓。Do as you are told.按照人家告訴你做的去做。She looks as if she is ill.看上去她好象是生病了。He acted as if nothing had happened.他的行動就好象什么也沒有發生。They treat the black boy as if he were an animal.他們對待這黑孩子仿佛他是一頭牲口。

八、讓步狀語從句

1.在句子中一般用了“雖然”就不能再用“但是”但可以與yet或still連用。though / although意義相同，用法基本一樣，前者通俗，口語化，后者正式多放主句的前面。Although he was over sixty, he began to learn French.雖然他六十多歲了，但仍開始學習法語 .We were not tired though we had worked all day.雖然我們干了一天活，但并不累。2.even if 和even though的意思為“即使”“縱使”有退一步設想的意味，多用于書面語中。I’ll go even if it rains tomorrow.即使明天下雨，我也要去。3.as引出的狀語從句多用于書面語，它比用though或although引導的從句，語氣強，更有表現力，從句常放在句首，語序部分倒裝。Child as he is , he knows a lot.雖然他是一個孩子，但他懂得很多。Cold as it is, the children play outdoors.雖然天氣冷，但孩子們仍在戶外玩。4.no matter...與 who-ever引導的讓步狀語從句意義基本一 樣，no matter...引導的從句可是以位于主句前或主句后。Do it no matter what others say.不管別人怎么說，盡管干。No matter how busy he was, he studied English every day.不管他多忙，他都每天堅持學習英語。No matter who takes up the matter for me, I shall be very grateful.不管誰為我處理這件事，我都將非常感激。5.wh-ever從句中的動詞有時可以和may連用。判斷wh-ever引導的是狀語從句還是名詞性從句的一點是，名詞性從句，主句中一定有一個成分要在從句擔任，一般從句與主句之間沒有逗號。不可將no matter與wh-ever連用。I'll try to give whatever you want.我會盡量滿足你的所需。Whatever happens / may happen, we shall not lose heart.無論發生什么，我們都不要失去信心。Whoever comes, he will be welcome.無論誰來，都會受到歡迎。

九、比較狀語從句

1.連詞表示同程度級的比較，肯定句用as…as否定句可用not as…as 或not so…as，從屬連詞有as…as, not so/as…as, the same…as, such…as。Mary is as old as my sister.瑪利和我姐姐一樣大。He doesn’t run so fast as Jack .他不如杰克跑得那樣快。His book is the same as mine.他的書和我的一樣。Henry is not such a good worker as Peter .享利這個工人不如彼得那樣好。2.表示不同程度之比較，主句中用比較級的形容詞或副詞。從屬連詞為than。She has made greater progress this year than she did last year.她今年比去年進步更大。He bought fewer books than I .他買的書比我買的少。3.the more…the more 意思為越……越……，通常的語序為從句在前主句在后，這兩個the都是表示程度的副詞，用在比較級的形容詞或副詞前面。句子意思明顯，句子的主語和動詞都可省略。The more you read, the better you understand.你看的書越多，你懂得的就越多。The more tickets you sell, the more money you will get.你賣的票越多，你的收入也越多。The harder you work, the greater progress you will make.你工作越努力，你取得的進步就越大。The sooner, the better.越快越好。The warmer, the better.越暖和越好。
