课件46张PPT。状语从句 状语从句状语从句的考查重点, 引导状语从句的连词、状语从句的时态等方面, 四种:时间状语从句、条件状语从句、结果状语从句和比较状语从句。 一、时间状语从句 引导时间状语从句的连词有:while, when,as,as soon as,until,not...until,before, after,since,etc. 要掌握每个连词的含义及其用法,还有它们之间的一些区别。 when,while的区别: ①二者均可表示“当……的时候”,如果主句表示的是短暂的动作,而从句表示的是一段时间,二者可通用。如: I met Kang Li when/while I was walking along the street. 当我沿街散步时碰见了康丽。 ②when可与短暂性动词连用, while只能与延续性动词连用。如: It was snowing when we got to the airport. 当我们到达机场时,天正下着雪。(不能用 while) 3)until=till在肯定句中表示“直到……为止”,主句要用延续性动词; 在否定句中,表示“直到……才”,主句常用短暂性动词,这时till和until可用before替换 I waited till/until he arrived. We won’t start until/before Bob comes.4)since从句中常用过去时,主句用现在完成时; as soon as如果主句是一般将来时,情态动词加动词原形或祈使句时,时间状语从句用一般现在时。如: Where have you been since I saw you last?上次我和你见面之后,你到哪里去了? I'll phone you as soon as I arrive in Tonghua.我一到通化就给你打电话。 2.考例: 1)我一到美国就给你打电话。 I'll ring you up _____ soon _____ I get to America. 2)昨天直到雨停了,孩子们才离开学校。 The children _____ leave school _____ the rain stopped yesterday. asasdidn’tuntil3)It _____ ten years since they _____ to France.

A.won't rain B.doesn't rain C.don't rain D.isn't raining 2) _____ you eat old food,you may be ill. A.Before B.Why C.If D.Which BC 三、比较状语从句 1.引导比较状语从句的连词有as...as,than。 1)表示甲与乙在某一方面相同时,用“as+原级+as”句型; 表示甲在某一方面不如乙时,用“not as /so +原级+as”句型。如: Dalian is as beautiful as Shenzhen. I don't run as/so fast as Kang Li. 2)表示甲超过或不及乙时,用“比较级+从句” 如: He runs faster than you(do). 他跑得比你快。 Today is less cold than yesterday. 今天没有昨天冷。 四、结果状语从句 ... ...
