2015中考英语 常考易错点 专题四 数词.doc

数词易错清单　　1. 确数和约数(1)当我们说“几百”、“几千”这样一些确数时,“百”、“千”是不能用复数形式的结构是:数词+hundred/thousand/million/billion+名词复数　如:five hundred五百;three thousand三千;two million两百万;six billion六十亿2)当hundred,thousand,million加上s后,它们就成了概数,表示“数百”、“数千”、“数百万”等概念而且通常接of,表示“成百的”,“数以千计的”,“成千上万的”,“亿万的”等结构是:hundreds/thousands/millions/billions+of+名词复数如:hundreds of new tall buildings数以百计的新高楼;thousands of students数以千计的学生;millions of people数以百万计的人2. 数词和冠词的关系(1)一般情况下,序数词前要加定冠词the,但基数词前不加冠词如:He failed in the first try. 他第一次尝试失败了My number is forty-nine.我的号码是49。

2)a/an+序数词,表示“又一、再一”如:The monkey ate a second banana.这只小猴又吃了一根香蕉3)of the+基数词,表示“范围”如:You can choose a toy of the two as a birthday present.你可以在这两个玩具中选一个作为生日礼物3. “数词+more”与“another+数词”(1) 表“另外的”接复数名词,如与具体数词连用,则置于数词之后,但与定冠词the连用时,other要放在数词前如:Mr Smith asked me to fetch another three CDs.史密斯先生让我再拿三张CD2) more一般位于数词之后名词前,有时也可置于名词之后如:She has got five more pens.她还有五支钢笔3) more除跟数词外,还可与a little,a few,a lot,several等词连用,而且名词也可以是不可数名词如:I'd like to buy a few more books.我想再买几本书There are many more dictionaries on the desk.课桌上有许多词典。

Would you like some more tea?再喝点茶好吗?提分策略　　英语中的数词看似简单,实际上运用时并不简单,有很多需要注意的地方近几年中考对数词的考查主要集中在基数词和序数词的辨析用法上日期、时间和分数也是中考考查的考点数词考查往往与其他知识点考查结合进行,如主谓一致等正确解答数词有关问题,需要熟记基本词汇,掌握一定解题策略1. 熟练掌握基础知识在复习过程中,要系统归纳、数量掌握数词的构词法以及各类数词的基本用法特别是日期、时刻、年龄、分数的表达形式这样解题才能得心应手例1】　(2014·广东·29)It's never too old to learn.

分数的表达方式是,分子用基数词,分母用序数词分子超过2时,分母要复数形式2. D　解析:考查数词、名词和代词的用法再需要两个小时”,应该用“need another+数词+复数名词”结构It takes sb. some time(花费某人一段时间)”是固定句型3. D　解析:考查交际应答疑问句是询问对方什么时候进行校际旅游的,应答句应该用表示过去的时间状语,不是“五天以后”、“五天”或“一天两次”4. C　解析:考查复合形容词的用法five-year-old 这类复合词可以用作形容词,意为“五岁的”,并且其中表示计量的名词(如year,month等)总是用单数形式这类结构通常用作前置定语,不用作表语(作表语时可改用seven years old这样的形式),排除B项又因为five years old在句中作表语,也排除,修饰boy只能用five-year-old5. A　解析:考查时间的读法按英语的习惯,顺读法表示时间直接说即可,six ten符合题意要求其他三项均不合乎题意,应该排除故正确答案选A6. A　解析:考查分数的表达英语分数词常用基数词作分子,用序数词作分母分子超过一时,分母用复数形式。

故选A7. B　解析:考查数词的用法hundred 与具体数字连用时,用单数分数表达法:在表达分数时,分子用基数词,分母用序数词,分子大于一时,分母用复数8. B　解析:考查分数及主谓一致的用法句意:地球将近四分之三被海洋所覆盖表示分数时,按英语的习惯,分子大于“1”,分母加“s”另外,主语指的是一部分,看作一个整体,因此谓语动词应该用单数符合句意要求的应该是B,其他三项均不合题意,应该排除。
