第二部分句类语法复合句（pound Sentences）Diligence result in success. 成功源于勤奋必考考点1：宾语从句◇B宾从①宾语从句的概念[宾语从句]即指在[主从复合句]中用作[宾语]的从句。

[宾语从句]的[词序]要用[陈述语序]·I don’t know what does he want.（×）·I don’t know what he wants.（√）巧思：什么是[陈述语序]？①[陈述语序]是指[陈述句的语序]：[主语+ 谓语+ (其他)]a. [主语]指：[名词]、[代词]、[动名词]和其他可以作[主语]的成分如：Apple He Doing Fiveb. [谓语]指：[（情态动词）] + [（助动词）] + [实义动词]部分（带括号的可以没有）②[宾语从句]的[陈述语序]是指：a. [引导词] + [主语] + [谓语] + [（其他）]如：I asked what he need.我问他需要什么。

b. [引导词] + [名词] + [主语] + [谓语] + [（其他）]如：Tell me whose wallet this is.告诉我这是谁的钱包。

c. [引导词] + [谓语] + [（其他）]：[引导词]作[主语]如：I don’t know who likes you.我不知道谁喜欢你。

②宾语从句的引导词a. 用[that]引导：[that]只起[引导词]作用，不充当[句子成分]，也没有[词义]，且通常可以[省略]·We think (that) he will help us.我们认为他会帮助我们。

·He said (that) he was good at English.他说他擅长英语。

b. 用[if]或[whether]引导：[if]和[whether]引导[宾语从句]，不充当[句子成分]，词义为“是否”·I don’t know if/whether he will e.我不知道他是否会来。

专题十二并列句和复合句一对一“梳理”知识点高效复习法并列连词and, but, or, so是中考的高频考点,这些词所表示的逻辑关系要理解吃透.并列连词连接的是两个或两个以上的并列成分,如两个词、两个短语或两个分句.做题时要仔细审题,弄清题意,抓住关键词来推敲并理顺前后的逻辑关系.复合句是由一个主句和一个或一个以上的从句构成,主句为句子的主体,从句只用作句子的一个次要成分,从句通常由关联词引导,并由关联词将从句和主句联系在一起.从句按其在复合句中的作用分为宾语从句、状语从句和定语从句.宾语从句是中考单项选择的常考点,侧重于引导词、时态、句意和语序的混合考查,考生在做宾语从句类试题时,首先应从语序着手,宾语从句的语序为陈述语序,即:主语＋谓语＋宾语＋其他,若选项不是陈述语序,则可以直接排除.其次,从时态方面考虑,一般情况下,宾语从句的时态要和主句的时态保持一致,但是,如果有明显的时间状语,则要根据时间状语来判断时态.最后,根据语境来判断疑问词,询问内容用what;询问时间用when/what time;询问地点用where;询问原因用why;询问方式用how等.定语从句主要考查的是关系词.考生在解答定语从句类试题时,可按以下步骤解题:(1)首先根据语境分析句子结构,找出先行词.(2)然后判断先行词是指人还是指物,缩小关系词的选择范围.(3)最后把先行词还原到定语从句中,明确先行词在定语从句中所作的成分,如果从句缺少主干成分,用关系代词;如果从句不缺主干成分,用关系副词.(4)特殊情况.牢记只能用that的几种特殊情况,结合题目做出判断.对状语从句的考查主要集中在从属连词的词义辨析上.解答此类题时一定坚持“句意为先”的原则.准确地翻译句意,就能准确判断出主、从句的关系和从句的类型,选择连词也就容易多了.主句和从句的时态搭配对状语从句引导词的判定也有帮助.如:含条件状语从句的主从复合句,主、从句的时态遵循三大原则“主将从现”“主情从现”和“主祈从现”.知识突破知识点1并列句一、定义:由并列连词连接的两个或两个以上的简单句组成的句子叫做并列句.二、并列句有四种关系:并列关系,选择关系,转折关系和因果关系一、定义:在句子中担任宾语的从句,就是宾语从句.二、用法1.宾语从句三大考点(1)动词不定式与疑问词连用可用作主语、宾语或表语.例如:When to go to Beijing hasn't been decided yet.什么时候去北京还没定下来.(作主语)I asked him when to leave Beijing.我问他什么时候离开北京.(作宾语)My question is how to get there.我的问题是如何到达那里.(作表语)(2)“疑问词＋动词不定式”作宾语时可以转化为宾语从句.例如:Can you tell me where to buy a map of China? = Can you tell me where I can buy a map of China?你能告诉我在哪里能买到中国地图吗?3.否定前移当主句的主语为第一人称,谓语动词是think, believe, suppose等时,要将宾语从句的否定词转移到前面的主句中,即主句的谓语动词用否定形式,而宾语从句的谓语动词用肯定形式.例如:I don't think he will come with you.我认为他不会和你一起来.I don't believe she will take part in the English evening.我认为她不会参加英语晚会.知识点3状语从句一、定义:在句中作状语成分的从句就是状语从句,它在句中修饰动词、形容词、副词或整个句子.二、用法1.常见的状语从句(1)时间状语从句.(6)结果状语从句.在时间状语从句和条件状语从句中,主句和从句一般有以下两种时态:(1)“主将从现”:主句用一般将来时,从句用一般现在时.例如:I will go swimming as soon as I finish my homework.我一完成作业就去游泳.(2)“主祈／情从现”:若主句是祈使句,或主句中有情态动词时,从句用一般现在时表示将来.如①Please let me know if he comes back.如果他回来了,请告知我.②If you feel hungry, you should eat something.如果你饿了,你该吃点东西.知识点4定语从句一、定义:在复合句中作定语,修饰主句中某一名词或代词的从句叫做定语从句;被修饰的名词或代词叫做先行词,引导定语从句的词叫做关系词.二、用法1.关系代词和关系副词的用法(1)当先行词是all, none, little, much, some, everything, anything, nothing等不定代词或被其修饰时.例如:Please get everything ready that we need.请准备好我们需要的一切.(2)当先行词前面有the only, the very, the last, the same等修饰时.例如:He is the only person that I want to see.他是我唯一想见的人.(3)当先行词被序数词或形容词最高级修饰时.例如:This is the most interesting book that I have ever read.这是我读过的最有趣的书.(4)当先行词既有人又有物时.例如:They talked about the people and things that they remembered in school.他们谈论着他们在学校记得的人和事.(5)当主句是以who或which开头的特殊疑问句时,为避免重复应用that.例如:Who is the person that is standing at the gate?那个站在门口的人是谁?3.关系代词中不能用that的情况(1)介词之后不能用that.例如:This is the factory in which we once worked.这就是我们曾经工作过的工厂.(2)非限制性定语从句中.例如:This is my favorite pen, which I bought yesterday.这是我最喜欢的钢笔,我昨天买的.(3)当先行词本身为that/those时.例如:You must find out those which may be ignored by us.你必须找到那些可能被我们忽视的东西.核心考点,各个击破考点1并列句例1(2022·河北,33题,1分) I saw a good film,________ I can't remember its name.A. soB. orC. forD. but【解析】本题考查连词辨析.句意:我看了一部好电影,但我记不起它的名字了.根据前后句句意可知,空前后之间为转折关系,使用连词but.答案:D针对性练习11.Study hard, ________ you will pass the exam.A. soB. orC. butD. and2.-Would you like to go to the concert with me?-I'd love to, ________ I'm afraid I have no time.A. soB. orC. andD. but3.At school, we are taught________ knowledge________ how to behave well.A. neither; norB. either; orC. not only; but alsoD. not; but考点2宾语从句例2(2021·湖北黄冈,33题,1分)-I think it's difficult to write the book report in two days.
