初中英语中考单选题解题方法技巧整理(共15个)

中考英语单选题解题方法技巧01.直接法直接利用相关语法知识，通过题干中的已供信息，捕捉到解题线索，从而得出正确答案的解题方法。

例：--Will you come to the net bars(网吧)with me﹖--Sorry．My mother always tells me______ there．A.not goB.goC.not to goD.to go根据句意可知此题考查动词不定式的否定形式，即tell sb.not to do sth．，故此题应选C。

02.关键词法许多题目中都有这样一些词，它们对于快速而准确地判定答案起着至关重要的作用。

我们称这些词为关键词key words。

找到句中的关键词，也就找到了解题的突破口，例：--He hardly hurt himself in the accident，______ ﹖A.doesn＇t heB.didn＇t heC.did heD.does he该题中hardly与hurt是起关键词作用的。

凡陈述部分含有hardly， never， little， few等否定意义的词时，反意疑问句用肯定形式；而hurt一词的过去式与原形相同，此处hurt未加s，应为过去式。

因此本题答案C是正确的。

03.记准固定搭配My cousin and I often ______ on Sundays.A.play footballB.play the footballC.plays the footballD.plays football在本题中，play football是固定短语，play和球类之间没有任何冠词，所以B和C 同时被排除了。

主语是my cousin and I，所以play不加s，D也被排除了。

只剩下A是准确答案了。

04.牢记动词的固定用法I like_______very much and I’d like ______with my friends this afternoon.A.swimming; to swimB.to swim; swimmingC.swimming; swimmingD swim; to swim在本题中，考查了两个固定短语，前者是like doing，后者是would like to do，分辨清楚这两个短语结构，就能准确选出A。

2020年中考英语单项选择的解题方法

中考英语单选填空的解题方法单项选择是一种容量大、考查面广的题型，它集中考查词法、句法、语法知识。

因此在各级各类考试中，单项选择是必不可少的题型。

要做好单项选择题，首先必须熟练掌握句型、固定搭配、习惯用法、语法等方面的基础知识。

还应该了解一些解题技巧，提高解题的综合能力。

常用的解题方法有：类推法、代入法、直接法、排除法、换位法、补全法。

1.类推法1.The young woman was often seen _______in the park.A. to drawB. drawingC. drawD. drew解析：此题容易误选B或C。

本句的句意是“经常看到这个年轻的女人在公园里画画。

”题干后主语与动词see为被动关系，而see用作被动语态时，结构为“be seen to do sth.”所以正确答案应为A。

2.代入法—What are you doing?—I’m ______the key to the door.A.looking afterB.looking forC.findingD.looking解析：此题容易误选C，这是由于思维定势引起的。

根据句意可知，“我在寻找门钥匙。

”look after意为“照顾”，look for意为“寻找”，find意为“找到”，将look for带入句中，符合题意，所以正确答案应为B。

3.直接法—Don’t make any noise in the living room! My baby is sleeping.—_____________.A. Sorry, I won’tB. It doesn’t matterC. Excuse me, I’m wrongD. Certainly, I won’t解析：此题容易误选 C 或D。

一方面可能由于不知道Excuse me. 与Sorry. 的区别，而误选为C；另一方面可能由于不理解这一语境而误选为D。

2020届中考英语总复习中考题型攻略篇单项选择精讲精练

题型二单项选择题型特点单项选择题的特点是考点多,覆盖面大,题量大,潜隐性较强。

预计2020年单项选择题的题量保持10道题的可能性会很大,并且增加干扰项的个数,选项由3个变为4个。

由于题量的减少,所以考点也变得更细更精。

并且根据近几年的考题,可以看出单项选择考查纯语法的题目逐渐减少,而增多了许多在特定的语境中运用词法、句法、习惯用法的考查,突出了对学生综合运用英语语言能力和日常交际用语的考查。

解题策略近几年来2019的单项选择题逐渐减少了对语法结构的考查,增加了对语境的考查,采取语义、语法相结合的方式,题目覆盖面广,灵活多样,交际性强,体现了新课标中提倡交流、强调运用、鼓励创新的理念。

10道单项选择题一般建议作答时间为6—7分钟,这样可以为后面的完形、阅读等题节约更多的时间。

(2019中考)从下列各题所给的A、B、C三个选项中选出可以填入空白处的最佳选项。

( )1.—I can't find Jimmy.Where is he?—He________in the garden at the moment.A.worksB.will workC.is working【解析】句意：——我找不到吉米,他在哪儿？——此刻他正在花园里工作。

根据“at the moment”可知应用现在进行时态。

【答案】C( )2.Every morning he spends ________hour doing exercise,then he goes to ________work.A.an；\B.a；aC.a；\[ZK)]【解析】句意：每天早晨他花一个小时做运动,然后去上班。

2020年中考英语单项选择解题技巧与方法(推荐)

2020年中考英语单项选择解题技巧与方法(名师精讲必考知识点+实战训练，建议下载练习)做题目标：1.分析中考单项选择题的考查内容和命题特点。

2.总结单项填空题的做题技巧并教会学生如何做单项填空。

学生的单项选择题得分率较高，但还存在着以下问题：一部分学生做题凭感觉；一部分知道答案而不知原因；只有少数同学做题有方法、有技巧。

重点难点:分析单项填空题的命题点及答题技巧，教会学生做单项填空题。

一、单项选择题的考查内容考查重点：代词、名词词义辨析、介词、连词、形容词及副词比较等级、动词短语、情态动词、时态、被动语态、宾语从句。

次重点：动词词义辨析（实意动词和感官动词交替考查）、形容词辨析、There be 句型、how词组、反身代词、指示代词、主谓一致、动词不定式、感叹句。

二、单项选择的命题原则及特点：重语用,重语境,重交际,轻语法河北省单项选择题主要考查基本语法、固定搭配、句式结构等。

1、以“语境”为载体,考察学生对语法和词汇知识的运用,试题呈现综合化的特点2、以“对话”为平台,考察学生对习惯用语的掌握,试题呈现口语化特征。

3、试题与学生的生活实际紧密相连,体现语言的时代性和实用性。

4、选项本身在语法和形式上应该是正确的(每个选项放到题干里时应合乎语法)三、复习及解题注意事项：单项选择题所考查的范围较广，所以要想做好此类题一要具备扎实的英语基础知识，二要紧扣语境，抓住关键词。

具体应注意以下几点：1、复习时要弄清初中阶段所出现的几种主要时态和语态的用法、结构、与之连用的状语及各自的特殊用法。

重点要分清现在完成时、一般过去时的用法。

对宾语从句、状语从句、动词不定式、比较等级以及它们的用法规则都要一一弄清楚。

还要注意固定搭配、习惯用语、动词的时态和语态、动词辨析以及不同词性的词的用法。

2.在解题方面要注重语境，在语境中选语句和词汇，防止汉语思维的干扰。

英语中一些关键词的含义往往是由它所处的语义环境(即上下文)决定的，答题时如忽视了语境，就很容易答错题。

它可集中考查词法、句法、语法知识。

因此在各级各类考试中，单项选择是必不可少的题型。

要做好单项选择题，首先必须熟练掌握句型、固定搭配、习惯用法、语法等方面的基础知识。

还应该了解一些解题技巧，提高解题的综合能力。

解答单项选择题，一般要经过四个阶段 :阅读审题——观察分析——选择判断——复查验证。

1. 阅读审题 :首先要默读试题中的英语句子，了解空格在句中所处的位置，句子缺少什么成份，初步确定一个答案的范围。

根据备选答案二者结合起来就会大致明白考查什么。

例如 :He goes to work by bus .A. So do IB. I so doC. I do soD. So am I默读此题后，就不难知道，此题缺少的是一个跟前句有关的一个句子；再根据选项就会清楚此题是考查副词“so”一词的用法(前边的情况也适于另一个人或物)，只能选A。

2. 观察分析 :这是一个快速而又严密的思维过程。

要求将试题中所提供的条件和备选答案的情况结合起来去分析、推理、排除那些明显不符合试题，甚至本身就有错的各选项目，再在剩余的备选中比较分析。

例如 :Wang Fang is young，but she plays ping-pong her mother.A. as good asB. as well asC. as better asD. as best as根据观察分析就会清楚，C、D两项本身就不能成立，应先排除，只能在A、B两项中选。

3. 选择判断 :在分析句子和备选答案的基础上，经过反复验证，选出一个使句子语法正确、语意通顺，附合逻辑道理的答案。

就上例所示，先排除了C、D，就在A、B两者中选。

因句中“play”为一个行为动词，需用一个副词来修饰，故应选择B。

4. 复查验证 :将所选答案放在句中空格处再默读全句。

首先看是否顺口，再在读法、意思和逻辑关系上推敲一下，完全符合条件则可放心。

专题01非限制性定语从句(原卷版)

专题01非限制性定语从句(期中重点语法)知识串讲非限制性定语是对被修饰名词或代词的附加说明，它不是必需的，如果去掉，也不会影响句子的意思，它与被修饰名词之间通常用逗号分开。

如：The travellers, knowing about the floods, took another road. 游客们知道发了大水，都改道走了。

My gardener，who is very pessimistic，says that there will be no apples this year.我家的园丁非常悲观，他说今年将不结苹果。

非限制性定语从句用法：1、引导非限定性定语从句时，只能用which(不用that)。

例如：Heat is another form of energy, which is as important as other kinds of energy.热是另一种形式的能量，与其他形式的能量一样重要。

（从句表补充说明，而且关系代词which不能换成that。

）2、引导非限定性定语从句的which可以指代前面的先行词,也可以指前面整个句子的含义。

例如：That Peter will marry Alice, which has not been announced yet, has spread around.彼特要娶爱丽斯这件事还没宣布，却已传得沸沸扬扬。

（句子中的which指“彼特要娶爱丽斯”这整个句子的意思。

）3、除which外，还可用when，where，who等关系代、副词引导非限定性定语从句。

whom引导的非限制性定语从句。

关系代词whom用于指人，在句中作动词宾语和介词宾语，作介词宾语时，介词可位于句末。

如：Peter, whom you met in London, is now back in Paris.彼得现在回巴黎了，你在伦敦见过他。

whose引导的非限制性定语从句。
