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？ My mother was coo

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

19、经过坚持不懈的努力，他终于考上了广州的一所大学。 1after 根据语境“Michael上了高中后就开始努力学习”。 2until “直到才”是固定用法，“延续性动词until句子”用肯定形式，而“not短暂性动词until句子”则用否定形式。 3unless 根据句意“除非他取得满意的成绩，否则他是不会放弃的”可知。 4as 引导让步状语从句时，从句中的状语、表语或动词置于句首，意思是“尽管”。 5because 根据前面可知“尽管他没有取得很大的进步，但是他毫不气馁，因为他坚信只要坚持，总会成功”。,6As 根据句意“随着时间的流逝”，只能用as。 7before 引导时间状语从句，意思是

20、“在之前”。 8Since 从下文“we had a very good time”可以推断出，此从句是原因状语从句，从句在主句之前，常用since，意思是“既然”。 9where 动词stood是不及物动词，其后跟的是表示地点的状语从句，意为“站在曾经学习和玩耍的地方”。 10wherever 从下文“or whatever we would do”可知，前面是一样的结构，从句缺状语。 11although/though 从下文的“we still fought back the tears”可知前面是让步状语从句。 12than 从前面的“a little sadder”可知是比较状语，用
