【英语】中考英语语法填空易错题经典 一、初三中考语法填空（含答案详细解析） 1．阅读下面短文，在空格处填入一个适当的词或使用括号中词语的正确形式填空。 Strangely enough, some inventions are lost ________ people can't imagine their ________ （valuable）. A use may need to be "invented" along with the invention. An example is the fax machine. The technology for faxing ________ （invent）in the 1800s. It took more than one hundred years, however, for the fax to be seen as useful. In 1843 Alexander Bain invented a machine to ________ （electrical）transmit（传输）writing. At first, it was considered ________ （use）since few people thought there was ________ need for transmitting writing over ________ （wire）. Eventually the value of the invention was realized, and it was improved ________ office use. By the 1980s, the fax machine became a piece of standard ________ （equip）in offices. The reason is ________it can very quickly transmit written documents. Who knows how many other inventions just need to be recognized as valuable? 【答案】because；value；was invented；electrically；useless；a/any；wires；for；equipment；that 【解析】【分析】主要讲了一些发明因为人们不能想象它们的价值而失去，列举传真机器的发明来说明这点。 （1）句意：足够奇怪的是，因为人们不能想象它们的价值，所以一些发明消失了。后句表示原因，所以用because；形容词修物主代词修饰名词，their它们的，形容词修物主代词，所以后面用形容词valuable的名词value，不可数名词，故填because，value。 （2）句意：传真的科技在19世纪被发明。invent发明，实义动词，主语technology是动作invent的承受者，时态是一般过去时，所以用一般过去时的被动语态，结构是was/were+动词过去分词，主语technology是不可数名词，所以用was，invent的过去分词是invented，故填was invented。 （3）句意：1843年，亚历山大贝恩发明了一种电子传输文字的机器。electrical电子的，形容词，副词修饰实义动词，transmit传输，实义动词，所以用副词electrically，电子地，故填electrically。 （4）句意：起初，它被认为是无用的，因为很少有人认为有必要通过电线传输文字。be considere形容词，表示被认为怎么样，固定搭配，根据后文可知传真的作用后来才被认可，所以起初被认为是无用的，use使用，实义动词，其形容词是useless，无用的；原因是很少人认为有必要，few表示否定，所以用a/any；wire，电线，可数名词，前面没有表示单数的a或者one，所以用复数wires，故填useless；a/any；wires。 （5）句意：最终，这项发明的价值得以实现，并被改进为办公用途。为了办公用途才被改进，所以用for，为了，故填for。 （6）句意：到了20世纪80年代，传真机已成为办公室的标准设备。equip，装备，实义动词，形容词修饰名词，standard，标准的，形容词，所以用equip的名词equipment，设备，不可数名词，故填equipment。 （7）句意：原因是它能很快地传送书面文件。the reason is that...，原因是……，固定搭

中考英语：易错题500例,含答案,有解析(1)
1.---We’ll do what we can ____English well this term. ---It’s high time for you to work hard. A. study B. to study C. be studied D. be studying 这题可能会误选A，因为大家知道情态动词后接动词原形，但是请大家分析下句子的成分，这里的what we can 实际省略了do，这个what we can do 在句子中作宾语从句。正确答案是B，用动词不定式作目的状语。后面回答的it's time for sb.to do sth.....对某人来说是时候去做...这是固定用法。 2. ---I don’t think your team can beat theirs. ---____. But we could if Lin Tao were on the team. A. No, we can’t B. Yes, we can’t C. Yes, we can D. No, we can 在think，believe这类词接的宾语从句，否定要提前。而对于否定句的回答，与习惯相反，yes是“不”no 是“是的”B,D结构不正确，首先要排除。而我们看后面的BUT，表示转折，说明回答者的队没有打赢。那么就是we can't. 正确答案是A。翻译为“是的，我们没有赢” 3. ---Have you finished your work yet? ---No, not yet. I think it’ll take _____ ten minutes. A. another B. other C. others D. more another +数词+名词 固定用法，another表示“另外的，再” 根据题目意思，可以判断是需要再花10分钟，所以答案是A。 4. Roy made several kites, but _____ of them can fly hi gh in the sky. A. neither B. none C. all D. most

初中英语中考英语语法填空易错题精选经典 一、初三中考语法填空（含答案详细解析） 1．He was ________ （mention） in the letter. 【答案】 mentioned 【解析】【分析】句意：他在这封信里被提到了。mention是及物动词，根据句子机构可知是被动语态，be已经给出，行为动词使用过去分词mentioned，故答案是mentioned。【点评】考查一般过去时，注意动词过去式的变化规则。 2．阅读下面短文，在空白处填入一个适当的词，或填入括号中所给单词的正确形式。 An old man went to India. When he got there, he saw some fruit for sale, but most of it was very cheap. The ________ （cheap） thing has a basket of red fruit. "How much per kilo?" the old man ________ （ask）. "Two rupees （卢比）," the shopkeeper answered. Two rupees in India is almost nothing, ________ the old man bought a whole kilogram and started eating it. However, as soon as he started eating, his mouth began ________ （burn）, his eyes began to water, and his whole face became as red ________ the fruit. As he coughed and struggled to breathe, he jumped up and ________, screaming: "Ah! Ah! Ah!" And yet he continued to eat the fruit. Some people who were looking at him shook their ________ （head） and said, "You are crazy! Those are chili peppers （辣椒）!You can't just eat them by the handful!" The old man said to ________ （he）,"I paid for them, so I must eat them." This old man seemed pretty stupid. But are we so much smarter? All of us have ________ （spend）money and time on something-maybe a relationship, or a business, or a job-and sometimes, even if we know there's no hope that things will change, we still continue with it. What we can learn ________ the old man is this: if you've lost a lot over something that doesn't work, let it go and move on. It's better than continuing to lose. 【答案】cheapest；asked；so；to burn /burning；as；down；heads；himself；spent；from 【解析】【分析】文章大意：这篇短文主要讲述了一个人因为贪便宜，买了一些根本不能作为水果的辣椒。结果因为舍不得自己花的那些钱，坚持把它们吃完的故事。从而告诉我们放弃某些东西比继续损失要好。 （1）句意：最便宜的东西有一篮子红水果。cheap，便宜。根据上文语句but most of it was very cheap. 提示可知，此句应该用最高级，故填cheapest。 （2）句意：“每公斤多少钱？”老人问。ask，询问，由语句 An old man went to India. 提示可知此句要用一般过去时，故填asked。 （3）句意：所以这位老人买了整整一公斤，开始吃。语句the old man bought a whole kilogram and started eating it.是Two rupees in India is almost nothing, 的结果，故填so。（4）句意：然而，他一开始吃东西，嘴巴就开始燃烧。burn，燃烧；固定结构begin to do sth，开始做某事，故填to burn/burning。

中考英语易错题大全(经典)
中考典型易错题举例分析 1. It is _______ outside. Let’s put on our raincoats and go out, Tom. A. cold B. hot C. sunny D. rainy 【解析】此题易误为A。因为这里有个put on短语，如果不注意raincoats这个词那就很可能草率地选择A。raincoats是“雨衣”的意思，而不是一般的衣服，那么不是因为外面“冷”，而是因为“下雨”才穿“雨衣”。正确答案为D。 2. —_______ do you _______ about spring? —The flowers and the green trees. A. How, like B. How, think C. What, think D. What, like 【解析】此题陷阱选项为A或B或C。这是由于忽略语境造成的。由答语The flowers and the green trees. 可知，所问的是“你喜欢春天的什么?”而不是“你觉得春天怎么样?”。正确答案为D。 3. —What’s yo ur sister like? —_______. A. She is a worker B. She likes pears C. She is very thin D. She is like her father
【解析】此题陷阱选项为B或D。有很多考生一看题干中的like一词就会想当然地选择B或D。其实，问句的意思是“你姐姐长得怎么样?”因此，正确答案为C。What’s … like? 这个句型常常用来询问某人的长相或某事的情况(包括天气情况)。 4. —It’s too hot. Would you mind _______ the door?—_______. Please do it now. A. to open, OK B. opening, Certainly not C. opening, Of course D. to open, Good idea 【解析】此题陷阱选项为A。一方面是由于不了解mind的用法，另一方面的由于忽略造成的。mind后面接动词时要用其ing形式。由答语中的Please do it now. 可知“不介意”。正确答案为B。 5. —If you have any trouble, be sure to call me. —_______. A. I am glad to hear that B. I will. thank you very much. C. I have no trouble D. I will think it over 【解析】此题陷阱选项为A或D。由于受汉语思维的影响很容易选择A或D。其实，问句意为“如果你有麻烦，一定要打电话给我”，这是一个表示请求的句子，对于别人的请求要么拒绝要么接受，而不能含糊其辞。正确答案为C。 典型形容词和副词考题分析

第一章 三角形的证明
1.已知等腰三角形的两边长分别为 5 ㎝、2 ㎝，则该等腰三角形的周长是（D ）
A．7 ㎝
B．9 ㎝
C．12 ㎝或者 9 ㎝
D．12 ㎝
考查知识点：三角形的基本知识及等腰三角形边的关系：任意两边之和大于第三边，等腰三
角形两腰相等，
因此只能是：5cm，5cm,2cm.
2.一个等腰三角形的一个角是 40°，则它的底角是（D）
A．40° B．50°
C．60°
D．40°或 70°
考查知识点：三角形的内角和及等腰三角形两底角相等：①当 40°是顶角时，底角就是 70°；
②40°就是一个底角.
3.已知△ABC 的三边长分别是 6cm、8cm、10cm，则最长边上的高是（D）
A.2.4cm
B.3cm
C.4cm
D. 4.8cm
提示：设最长边上的高为
1 .6.8 1 .10.h
2
2
h,由题意可得△ ABC 是直角三角形，利用面积相等求，即
解得 h=4.8
3 4.等腰三角形一腰上的高与另一腰的夹角为 30 ，腰长为 6，则其底边上的高是3 或
3.
0
解：①三角形是钝角三角形时，如图 1，∵∠ABD=30°
11 ∴AD= 2 AB= 2 ×6=3，
∵AB=AC，
1
1
∴∠ABC=∠ACB= 2 ∠BAD= 2 (90°-30°)=30°，
∴∠ABD=∠ABC，
∴底边上的高 AE=AD=3；
②三角形是锐角三角形时，如图 2，∵∠ABD=30°
∴∠A=90°-30°=60°，
∴△ABC 是等边三角形，
∴底边上的高为
3 ×6=3 2
3
综上所述，底边上的高是
3
3 或
3
5.到三角形三个顶点的距离相等的点是三角形（B）的交点. A.三个内角平分线 B.三边垂直平分线 C.三条中线 D.三条高 考查的知识点：三角形三边垂直平分线的交点到到三角形三个顶点的距离相等【归纳为：点 到点距离相等，为垂直平分线上的点】还有一个：三角形三个内角平分线的交点到三角形三

18年中考英语易错题汇编 1. ---We?ll do what we can ____English well this term. ---It?s high time for you to work hard. A. study B. to study C. be studied D. be studying 答案：A， 解析：因为大家知道情态动词后接动词原形，但是请大家分析下句子的成分，这里的what we can 实际省略了do，这个what we can do 在句子中作宾语从句。正确答案是B，用动词不定式作目的状语。后面回答的it's time for sb.to do sth.....对某人来说是时候去做...这是固定用法。 2. ---I don?t think your team can beat theirs. ---____. But we could if Lin Tao were on the team. A. No, we can?t B. Yes, we can?t C. Yes, we can D. No, we can 答案：A， 解析：在think，believe这类词接的宾语从句，否定要提前。而对于否定句的回答，与习惯相反，yes是“不”no 是“是的”B,D结构不正确，首先要排除。而我们看后面的BUT，表示转折，说明回答者的队没有打赢。那么就是we can't. 正确答案是A。翻译为“是的，我们没有赢” 3. ---Have you finished your work yet? ---No, not yet. I think it?ll take _____ ten minutes. A. another B. other C. others D. more 答案：A， 解析：another +数词+名词固定用法，another表示“另外的，再” 根据题目意思，可以判断是需要再花10分钟，所以答案是A。 4.Roy made several kites, but _____ of them can fly high in the sky A.neither B. none C. all D. most 答案：B， 解析：neither "两者中任何一个都不" all "三者或三者以上都" most"大部分" 根据题目意思，只有none表示“一个都没有”没有确定的数量，不知道是2个还是3个或3个以上。 5. ---Will you be back ____ five in the afternoon? ---I?m not sure, maybe later than that.
