状语及状语从句解析.docx

1、状语及状语从句解析状语(adverbial)是句子的重要修饰成分。状语是谓语里的另一个附加成分，它附加在谓语中心语的前面，从情况、时间、处所、方式、条件、对象、肯定、否定、范围和程度等方面对谓语中心进行修饰或限制。在英语中，状语修饰动词、形容词、副词等的句子成分。状语的功用：状语说明地点、时间、原因、目的、结果、条件、方向、程度、方式和伴随状况等。状语一般由副词、介词短语、分词和分词短语、不定式或相当于副词的词或短语来担当。其位置一般放在句末，但也可放在句首或句中。副词是一种用来修饰动词,形容词,副词或全句的词,说明时间,地点,程度,方式等概念。1.副词一般在句子中做状语He speaks E

2、nglish very well. 他英语说得非常好.中的very是程度副词，用来修饰well。very well是修饰speak的程度状语。2. 不定式在句子中可以作目的状语。I come specially to see you.我专门来看你.3.介词短语Ten years ago, She began to live in Dalian.十年前,她开始住在大连。The boy was praised for his bravery.4.从句作状语When she was 12 years old, she began to live in Dalian.If I am not busy

3、tomorrow, I will play football with you.5.分词作状语Having had a quarrel with his wife, he left home in a bad temper。Inhibited in one direction, it now seems that the Mississippi is about to take another.状语简介概述状语与定语相同的地方是,都是前者附加成分;不同的地方是,它是谓语里的附加成分,而定语是主语或宾语里的附加成分.从句子的层次上看,状语是在第二个层次和第三个层次里的成分,有时甚至是更低层次的成

4、分.状语的构成状语的构成经常充当状语的有形容词,副词,时间处所名词,能愿动词,指示代词,以及方位短语,介词短语,动宾短语,谓词性联合短语,谓词性偏正短语,谓词性主谓短语等.含有动量词的数量短语以及重叠式的数量短语(不论动量,物量)也可以充当状语.此外,少数名词带上表比况的助词也可以作状语.状语的书面标志地状语的书面标志是结构助词地.状语后面带或者是不带地,情况比较复杂.一般讲来,数量短语,主谓短语,动宾短语等作状语时,大都带地;而介词短语,方位短语,能愿动词,时间处所名词作状语时不能带地,副词,单音节形容词作状语一般也不带地.多层状语如果一个中心语前面有好几个状语(多层状语),那就应当注意它们

5、的语序.多层状语的状语个数一般比多层定语的定语个数要少些,其语序也比多层定语的语序要灵活一些.多层状语的一般语序:a.表时间的名词或方位短语,介词短语;b.副词.c.表处所的介词短语或名词,方位短语;d.表情态的形容词或谓词短语;e.表对象的介词短语.其中副词的位置较为灵活,也可放置在第三项之后.一般状语和句首状语状语在句子中有两种位置:一种是在主语之后,谓语中心之前,如上文所举各例,这是状语的一般位置;另一种是放在主语的前面的,这是状语的特殊位置,这种状语可称句首状语.状语的分类状语按其修饰的功能不同可分为八大类：时间状语，地点状语，条件状语，原因状语，目的状语，结果状语，让步状语和比较状语

6、时间状语从句要点: 时间状语从句，由以下连词引导：when ，while， as， after ，before， as soon as， since ，till /until by the time 在时间状语从句中，要注意时态一致。一般情况下主句是将来时的时候，从句要用一般现在时。1.when当.的时候Mozart started writing music when he was four years old.2.while当.时He visited a lot of places while he was traveling.3. as在.的同时；一边.一边.He smiled as h

8、I will write to you as soon as I get home.7.since 自.以来到现在表示自过去的一个起点时间到目前(说话时间)为止的一段持续时间。主句一般用现在完成时，从句用一般过去时。Mr Green has taught in that school since he came to China three years ago.(还可以用作介词，本句从句还可以用短语：since three years ago(自三年前以来)表示。)8 till /until都可以作连词，连接时间状语，也可以作介词，与其它词构成介词短语，在句中作状语。They walked t

10、 then you begin to know something.当你以为自己一无所知的时候，你就是在开始知道一些事物了。When truth is buried under the ground it grows, it chokes, it gathers such an explosive force that on the day it bursts out , it blows up everything with it.当真理被埋在地下的时候，它在生长，它感到压抑，它蓄存着这么一种爆炸性力量，一旦冒出，它就会炸破一切！Strike while the iron is hot. 趁

12、g.(瞬时动词)When I lived in the countryside, I used to carry some water for him.（延续性的动词）While引导的从句的谓语动作必须是延续性的，并强调主句和从句的动作同时发生（或者相对应）。并且while有时还可以表示对比。例如：While my wife was reading the newspaper, I was watching TV. (was reading是延续性的动词，was reading和was watching同时发生)I like playing football while you like pl

17、句用将来时，从句总是用现在时；如果before引导的从句谓语用的是过去时，则主句动词多用过去完成时，这样以便体现动作发生的先后。After表示主句动作发生在从句动作之后。主句和从句的动作的时间关系正好与before引导的从句相反。例如：It will be four days before they come back.

27、点状语从句 (adverbial clause of place)地点状语从句一般由连接副词where, wherever等引导，已经形成了固定的句型，要点: 由连词where和复合关系词wherever (=no matter where )引导.例如：句型1：Where+地点从句，（there）+主句。【注意】此句型通常译成“哪里哪里就”；主句在从句后面时，there可用可不用；如果主句在从句的前面时，一般都不用there。例如：Where there is no rain, farming is difficult or impossible.在没有雨水的地方，耕作是困难的，或根本不可能
