英语复合句的用法及解题技巧

英语复合句的用法及解题技巧在高考英语试题中，复合句占有较大的比例，复习时应该注意：１．倡发散思维，忌单向思维，考各种从属句，常常是不同类型的连接词语正误连缀而至，如果不抓住这一点，不从多方面思考选择，就容易以偏概全，误入歧途。２．弄清主从复合句中的每一个从属连接词的意思、用法、主句与从句在时态上的呼应、语气、是否需要倒装、固定搭配及逻辑常识等。３．熟记句型及特殊表达形式。４．注意各分句之间的特点及区别。５．注意有些连接词的省略情况及省略后某些语序发生的变化。总之在做习题时，不能生搬硬套，一成不变，要全方位的思考，摸清出题者的意图，灵活机动，随着不同的语言环境而变化。一、状语从句：状语从句又可分为时间、地点、目的、原因、结果、行为方式、条件、让步及比较等几种形式。１．I'll go with you as soon as I ____my work. A.will finish B.shall finish C.finish D.finished 选Ｃ．在时间、条件状语从句中，主句可能是祈使句、一般将来时或带情态动词，从句用一般现在时。如果主句是过去将来时，从句可以用一般过去时。能够引导时间状语从句、条件状语从句的从属连接词，常见的有：when,until （ti y,directly,unless,as long as,suppose等。如：（１）Unless he comes,we won't be able to go. （２）Suppose it goes on raining,what shall we do? （３）Lu Xun often said,"As long as I am alive,I shall go on studying." ２．No sooner_____the news than they rushed out into the street.

并列句和复合句英语从句

并列句和复合句一、并列句。并列句由两个或两个以上的简单句并列在一起构成。常见的并列句的结构是：简单句+并列连接词+简单句，这种简单句常被叫做分句。并列连词前可以用逗号，也可以不用逗号。常用的连接词如下：also, and, but, either…or…, however, not only…but also, or, or else, so, still, yet, neither…nor…等。他学习努力并通过了考试。 Let’s hurry, or we’ll be late. 咱们赶紧点，要不就迟到了。 I have been to Beijing many times, but my parents have never been there. 我去过北京多次，但我父母从没去过。 These flowers are white, and those flowers are red. 这些花是白色的而那些花是红色的。 I am a worker, but my brother is a professor. 我是一个工人，但是我的兄弟是个教授。注：当when作“就在这时（and just then）”解时，其引导的分句也是并列句。 Eg：I was wandering through the streets when I caught sight of a shop for

clothes. 我正在街上徘徊，就在这时，我突然看见了一家服装店。二、复合句。复合句是由两个或两个以上的简单句用某种连接方式连在一起的句子。在句子中作某一个成分的句子叫作从句。 1.从句由连接词引导。 2.从句尽管有主谓结构，但不能单独成为一个句子。在句中，从句仅担任某个成分。根据所担任的成分，从句可分为名词性从句（主语从句、宾语从句、同位语从句、表语从句）、定语从句和状语从句。 Eg：What he said is not true. 他说的不是实话。 I know it’s difficult to master English well. 我知道学好英语不容易。 The question is whether he will join us next time. 问题是下次他是否跟我们一起干。 The idea that Iraq could be taken within a week or two was an underestimation. 伊拉克在一两周内就可以被攻占的这一想法是估计不足（的想法）。 Do you know the man who is in the car? 你认识坐在汽车里的那个人吗？

初中英语-复合句

初中英语语法---复合句本部分内容是中考中必考及常考考点。考点详解：从句的概念：一个句子在另一个句子中充当成分，充当什么成分就做什么状语。一、宾语从句 1、宾语从句的引导词 ?宾语从句是陈述句时，常用that引导，that无意义，在口语中和非正式与中常省略。如： The teacher tells us (that) we will have an English test tomorrow. ?如果宾语从句由一般疑问句转换而来，其引导词用if或whether。一般情况下，二者可以通用，但从句中有or not或从句充当介词的宾语时，只用whether。如： I don’t know if\whether she will come here. Sorry, I don’t know whether he will come or not ?宾语从句是特殊疑问词时，引导词就是特殊疑问词。如： Could you tell me where the post office is ? The teacher asked the students what they were doing. 2、宾语从句的时态 ?主句的时态是一般现在时，从句的谓语动词的时态要根据具体的情况用相应的任何时态。如： Do you know who was talking with at 8 o’clock last night? ?主句的时态为一般过去时，从句的谓语动词要用相应的某一过去时态。如： He told me that he had been to England twice. ?从句表示的是客观真理、普遍现象，自然现象时，从句的时态一律使用一般现在时。如She said the sun rises in the east. 3、宾语从句的语序 ?在含有宾语从句的复合句中，宾语从句要使用陈述句语序，“引导词+主语+谓语+其他”。如： I want to know when the train left. ?由do,does,did构成的疑问句，在装换成宾语从句时，要去电do,does,did,且从句中的

初中英语复合句

初中重点语法从句按其在复合句中的作用,分为主语从句、表语从句、宾语从句、定语从句和状语从句等。（参见以下各条） 3、各从句在句子中的位置以及用法： (1) 表语从句：在句子中作连系动词的表语的从句,它位于主句中的系动词之后。例如：That is why he did not come to school yesterday. / It is because you are so clever. (2) 宾语从句：在句子中作及物动词或介词的宾语。 ①基本形式：（主句＋）连词+从句主语+从句谓语+... ②关于宾语从句连词的选择：若从句来源于一个陈述句,那么,连词用that,在口语中that可以省略; 若从句来源于一个一般疑问句,连词则用if 或whether; 若从句来源于一个特殊疑问句,则连词就是疑问词(如what,who,where,when等) 例如：They believe that the computer will finally take the place of human beings.(他们相信计算机终将代替人类。) (从句本来就是陈述句)/ I wonder whether I should say something for him to the headmaster.(我不知道是不是该为他在校长跟前说点什么。) (从句来源于一般问句Shall I say something for him to the headmaster?) / He asked me where he could get such medicine. (他问我在哪儿能搞到那样的药。) (从句来源于特殊问句Where can he get such medicine? ) ③宾语从句的时态问题：如果主句是现在时,从句则用现在某一时态,甚至可以用过去时；如主句是过去时,从句则相应地使用过去某一时态,遇到客观真理时仍然用现在时。如：I think I will do better in English this term. (我想本学期我的英语会学得好点。) / The teacher asked the boy if the earth is round. (老师问那个男孩地球是不是圆的。) ④下列结构后面的从句一般也作为宾语从句看待： be sorry / afraid / sure / glad +that从句,如：I’m sorry I’m late. (对不起,我迟到了。) / I’m afraid he isn’t in at the moment. (恐怕他此刻不在家。) (3) 状语从句：在复合句中作状语,其位置可以在主句前或主句后。状语从句可以分为时间、地点、原因、目的、结果、比较、让步、条件等几种。状语从句由从属连接词引导。时间状语从句通常由when ,as ,while, after, before, since, as soon as ,since, till (until), while, whenever 等引导。时间状语从句一般放在句首或句尾,特别注意,时间状语从句不允许使用将来时,而应该用现在时替代。如：When you finish the work, you may go out to play with Sam. (你完成工作就可以出去和Jim一起玩了。) / I won’t leave until Mum comes back. (妈妈回来了我才会走。) 地点状语从句通常由where, wherever等引导。如：Go back where you came from! (哪里来还滚到哪里去！) / I will never forget to catch the thief who stole my necklace wherever he may be. (我永远也不会忘记去抓住那个偷我项链的贼,无论他会在哪里。) 原因状语从句通常由because, since, as等引导,一般放在句首或句尾。如：He went abroad because his father had found a good university for him. (他出国了,因为他父亲给他找了一所好大学。) 目的状语从句通常由so that..., so...hat..., in order that...等引导,往往放在句尾,从句中通常含有can / could / may / might等情态动词。如：He got up earlier so that he could catch the first train. (他起身更早为的是赶上第一班车。) 结果状语从句通常由so that..., so...that... 等引导,放在句尾。结果状语从句一般表示已经发生的事情,故多为过去时态。如：He lost so many bikes that he decided never to buy a new one. (他丢了那么多辆自行车,他决定再也不买新车了。) 比较状语从句通常由as, than, as (so)...as等引导,一般省略从句的谓语部分,只剩下名词或代词(用主格或宾格均可)。如：Jane is much taller than I/me. (Jane比我高多了。) / I don’t have as many books as you (do). (我书没有你多) 让步状语从句通常由though (although), as, even if( even though), however, whatever等引导。如：Even if you pay the debt(债务) for me, I will not thank you because it has nothing to do with me. (即使你替我还了债我也不会感谢你,因为它与我毫无关系。) / He wears a T-shirt though it is very cold. (他穿了一件T恤衫,尽管天很冷。)

中考英语语法复合句

人教版中考英语专项练习复合句由一个主句和一个或一个以上的从句构成的句子叫复合句。主句为句子的主体，从句只是做句子的一个成分。根据从句在句子中的作用，可以把从句分为名词性从句（主语从句，宾语从句，表语从句和同位语从句），定语从句和状语从句（时间，地点，原因，条件，让步，方式，比较等）三类。一.宾语从句 1.宾语从句根据引导词的不同分为三种类型 ⑴由that引导的宾语从句，其中that不做成分，可省略。 We all knew (that) we should learn from each other. ⑵由if/whether引导的宾语从句。 Please tell me if/whether you have been to America. ⑶由who,where,how等连接代词或连接副词引导的宾语从句。 Can you tell me how I can get to the nearest post office? 2.宾语从句“三关” ⑴引导词关注意：whether与if的区别只用whether的情况 ①在介词后面 We don`t think about whether it would rain the next day. ②在动词不定式前 They asked me whether to sit at the front. ③当与or not连用，或提出两种选择时 Mary asked whether I was

doing my homework or not at that time ④宾语从句提前时 Whether this is true or not, I can`t say ⑤在动词discuss后的宾语从句中 We discussed whether we should have a sports meeting next week. ⑥引导表语从句或位于句首的主语从句用whether The question was whether he went there last night 只用if的情况 ①引导否定概念的宾语从句时 He asked me if I had`t finished my homework ②引导条件状语从句时，if意为“如果” We`ll go hiking if it doesn`t rain tomorrow ⑵语序关 ①宾语从句若为陈述句，语序不变 ②宾语从句若为一般疑问句或特殊疑问句，语序还原为陈述语序 ⑶时态关 ①如果主句是现在的时态，从句时态据实际情况而定 ②如果主句是过去某种时态，从句时态一定变为过去某时态注意：宾语从句表述的是客观真理，自然现象时，只能用一般现在时 3.人称变化： 4.从句简化 ⑴当主句谓语动词是find, see,watch,hear等时，从句常简化为“宾语+宾补”结构，宾补为省to不定式或v+ing形式

关于英语复合句的分析

关于英语复合句的分析 " 论文关键词:复合句名词性从句形容词性从句状语从句论文摘要：英语语法中复合句是一大难点和重点。高中阶段主要是学习复合句知识以及怎样运用这些知识解决语法题和提高阅读能力。如何学好复合句对英语学习和考试有极大的决定性作用。其实复合句是简单句的扩展，只要借助简单句的句型结构分析推理出复合句的主干结构，弄清从句是何种从句，然后再根据从句相应知识点解决语法问题或理解句子。复合句就是由主句加从句构成的。从句，指这个句子虽然能表达完整意思，但是它却是作为另一个句子（主句）的某成分而存在。主句与从句之间的关系就是，从句是主句的成分，从句可能是主语、宾语、表语、定语或者状语。两个简单句子组合成并列句需要并列词，那么主句与从句组合成复合句就需要关系词。主语从句需要的关系词与定语从句或状语从句需要的不一样，因此从句也有分类的。从句分三大类：名词性从句、定语从句和状语从句。名词性从句包括主语从句、宾语从句、表语从句、同位语从句。只要按步步为营的心态，解决复合句应该不会很难的。我们接触了简单句、并列句和复合句，我们怎样区别它们呢？在这里，我提出区别的标准：句子原则。句子原则1：一个句子只能有一个谓语，谓语由动词构成。

句子原则2：如果一个句子有多个动词，只有一个是谓语动词，其它为非谓语动词。句子原则3：如果一个句子有多个谓语，那么这个句子可能是并列句或者是复合句。如果有并列连词，就是并列句，如果没有就是复合句。以上的原则对句子分析是很有帮助的，请熟记之。虽然我们可以根据句子原则推理出复合句，但是怎样判断究竟是主语从句还是定语从句呢？如果要判断从句，我们按照"三步骤"分析句子。下面我们分析一些例子。 1、Who will go to the conference is not important. 句子中文意思：谁将参加会议并不重要。根据句子原则3，因为没有并列连词，所以是复合句。接下来，我们必须学会判断哪个谓语是主句的谓语，哪个是从句的谓语。首先我们看到who，可是句末不是问号，所以who 应该不是引导复合句的特殊疑问词而是关系词，因此who will go to the conference 是从句。那么is 就是主句的谓语，主句的句子结构是主系表结构，is 前面就应该是句子主语。从句who will go to the conference是主语，即主语从句。 2、The question is whether we shall run out of food soon. 句子中文意思：问题是我们的食物是不是很快吃完了。根据句子原则3，因为没有并列连词，所以是复合句。接下来，我们必须判断哪个谓语是主句的谓语，哪个是从句的谓语。首先我们看到whether，我们了解到whether 是引导名词性从句的关系词，那么whether引导的句子应该是名词性从句。那么shall run out of food 就是从句的谓
