中考英语单选易错题
大家知道，现在的中考英语试题总体不难，只要不放弃英语学习的学生都可以考及格以上，但欲考接近满分却并非易事。因为为了适当拉开学生距离，命题老师往往也会出一两个所谓的压轴题，以把那些真正的英语尖子生选拔出来。有时候我们学生与重点高中失之交臂，就是失分在下面我精选的难题上。 ( ) 1. ________ it is today! A. What fine weather B. What a fine weather C. How a fine weather D. How fine a weather 解析：选A. 此题容易误选B. weather是不可数名词，前面不能有不定冠词。英语中经常考查的不可数名词有work, news, adivice, information等。 ( ) 2. Which is the way to the __________? A. shoe factory B. shoes factory C. shoe’s factory D. shoes’ factory 解析：选A. 此题极易误选B, C, D. 英语中名词单数可以修饰名词，如：an apple tree →two apple trees. 但注意a man teacher→two men teachers。 ( ) 3. This class ________ now. Miss Gao teaches them。 A. are studying B. is studying C. be studying D. studying 解析：选A. 此题容易误选B. class, family, team等单词如果表示整体谓语就用单数，表示个体就用复数，从语境及其后面的代词them可以看出，class表示个体，故选择A。( ) 4. We will have a _________ holiday after the exam。 A. two month B. two-month C. two month’s D. two-months 解析：选择B 此题容易误选C, D. 在英语中数词中间用连字符号加名词单数，构成符合名词，在句中只能作定语，如果选择C, 需要把逗号放s后面。 ( ) 5. There is no enough ________ on the corner to put the table。 A. place B. room C. floor D. ground 解析：选B. 此题最容易误选A.。room在句中是空间而非房间。句意：角落里没有摆桌子的空间了。 ( ) 6. We can have _____ blue sky if we create _____ less polluted world。(苏州2010) A. a; a B. a; the C. the; a D. the; the 解析：选A. 此题容易误选C, D. 根据句意：如果我们创造一个没有污染的世界，那么我们就用一个蓝色的天空。 ( ) 7. —Are you ______ American or English? —English.. We are working in Wuhu. (芜湖10) A. a B. \ C. the D. an 解析：选B 此题容易误选D. 句中American是形容词而非名词，如果句中改为Are you __________ or an English man? 就选择D。 ( ) 8. You like playing basketball, and he likes running, _______? A. don’t you B. doesn’t he C. do you D. does he 解析：选择B. 此题容易误选A. 其实不是对前面的句中进行反问，而是对he likes running 进行反问。 ( ) 9. —Why not take ____umbrella with the sign “Made in China”？It is _____ useful umbrella? —What _______ good advice it is! A. an; an; a B. an; a; \ C. a; an; a D. \; an; a 解析：选B. 大多数学生容易做错此题。记住an用在元音音素前而不是元音字母前，记住了这一点就知道了an umbrella 和a useful umbrella. 在最后一句中advice是不可数名词，前面不能接不定冠词。故选择B ( ) 10. — When shall we meet again next week?
