专题四 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CD。 (2) 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. Karl Marx began to learn English in his . A. the fiftieth B. fiftieth C. fifty D. fifties 【解析】 考查数词的用法。短语“in one's+数词的复数形式”表示“在某人多少岁的时候”。此处表示“马克思在五十多岁时开始学英语。”故选D。 【答案】 D 【例2】 (2013·湖北恩施·23)Lindu's mother looks young,but actually she is in her . A. sixties B. sixtieth C. sixty years old 【解析】 考查数词用法。“in one's+表示几十的基数词”是固定短语,意为“大约几十岁”,此处表示在六十到七十之间。故选A。 【答案】 A 2. 巧用排除法 在考查数词时,有时所给选项非常相似。解题时,首先通过题干摸清出题人的考查意图,然后运用所学基本知识,排除所有不适合的选项。 【例】 (2013·云南·29)—How many people were invited to the meeting? —About six . A. hundred B. hundreds C. hundred of D. hundreds of 【解析】 本题考查基数词的基本用法。表达确数时,hundred,thousand,million等词不能加s。首先排除B、D。但是表示约数时,hundred,thousand,million等词与of连用,必须加s。这样又可以排除C。答案自然就是A。 【答案】 A 专项训练

A. three fourth;is B. three fourths;is C. three fourth;are D. three fourths;are 参考答案与解析
1. B 解析:考查分数的用法。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。故选B。 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。故选D。 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”。故选D。 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-old。故选C。 5. 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A。 6. 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A。 7. 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。故选B。 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
