2020年中考英语题型解题技巧专题01 单项选择(原卷版)

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。

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。

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。
