1、第五讲 状语从句 第一课时 知识过关课,李仕才,1在时间状语或条件状语从句中,通常用一般现在时代替一般将来时,用现在完成时代替将来完成时。 2辨析:when,while,as引导时间状语从句。while必须与延续性动词连用,强调主句动作延续到从句所指的整个时间时,只能用while;表示“随着”只能用as;表示有规律的“每当”时或主句动作与从句动作有先后时,只能用when。 3辨析:because,since,as引导原因状语从句。because语气最强,表示直接的原因,是说话人认为对方不知道的原因,它引导的从句通常位于主句之后;在回答why时,或者在强调结构中,只能用because。since
2、和as是对大家已知的事实提供理由或背景,它们引导的从句多位于主句前,有时也位于主句后。,4as引导让步状语从句时,从句中的状语、表语或动词必须置于句首;though引导让步状语从句时,这些成分可置于句首也可用正常语序;但although等其他词引导的让步状语从句不能将这些成分前置。 5表示“虽然”的连词though/although不能与表示“但是”的连词but连用;表示“原因”的because等连词不可与表示结果的连词so等同时使用。,读语篇,悟语法。反复朗读下列短文,领悟画线黑体部分。思考:有多少种状语从句?下面的状语从句各属于哪一种?有哪些特殊的用法?

7、 great hurry. Thats true. We should mind our step so that20 we can ensure our safety.,1用于对比两件事,意思是“而”用while,不能用when/as代替。 2as soon as引导时间状语从句,表示“一就”。 3before表示“还没来得及就”。 4名词词组如the moment/the second/the day/the first time/next time.等可以用来引导时间状语从句。 5引导表示原因的从句时用because,其引导的原因状语从句一般放在主句之后,而如果只是名词性短语表示原因,则
8、用because of引导。 6在表示比较时,用than来引导比较状语从句,than也可以作介词。,7对大家已知的事实提供理由或背景时,常用since引导,意思是“既然”。其引导的从句多在主句之前。 8引导条件状语从句,unlessif.not,是“除非,如果不”之意。 9after/before引导表示时间先后的状语从句,根据实际表达需要选用其一。 10when引导表示“当时”的时间状语从句。 11引导让步状语从句时,可以用although或though,主句可以与副词still连用,但不能再与连词but连用了,一个复合句只需一个连词。当是as引导让步状语从句时,从句中的状语、表语或动词置于
9、句首。,12however引导让步状语从句时,其后常接形容词或副词,用于修饰该形容词或副词,wherever,whenever也可以引导让步状语从句,在从句中作状语,相当于no matter how/where/when;另外whatever,whoever,whichever也可以引导让步状语从句。 13表示“随着”时,只能用as引导。 14引导地点状语从句时,用where/wherever,表示“在的地方”。 15固定用法“直到才”可以用两种表达形式:“延续性动词until句子”(用肯定形式);“not短暂性动词until句子”(用否定形式)。,16引导方式状语从句时,可以用as,意思是“
10、按照,像那样”。 17so that引导结果状语从句,从句表示的通常是某件事的结果。 18when引导表示“当时”的时间状语从句时,如果主句的主语和从句的主语是一致的,可以省略when从句的主语和be动词,用分词来表示。 19表示“即使,尽管”的even though/if引导让步状语从句。 20so that除了引导结果状语从句外,还可以引导目的状语从句,常与情态动词can/could等连用。,.单句填空(用适当的从属连词填空) 1_ hard you try, it is very difficult to lose weight without cutting down the amou
