1、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/
2、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
3、 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
4、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:Id 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
5、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)Its never too old to learn. Karl Marx began to learn English in his. A. the fiftiethB. fiftiethC. fiftyD. fifties【解析】考查数词的用法。短语“in ones+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
6、岁时开始学英语。”故选D。【答案】D【例2】(2013湖北恩施23)Lindus mother looks young,but actually she is in her .A. sixtiesB. sixtiethC. sixty years old【解析】考查数词用法。“in ones+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】A2. 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 inv
7、ited to the meeting?About six .A. hundredB. hundredsC. hundred ofD. 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1. (2014上海奉贤区32) of the city was covered with the heavy smog.A. Two-thirdB. Two-thirdsC.
8、 Two-threeD. Two-threes2. (2014广东深圳 11)I am afraid that we need .Havent you finished the work yet? It you such a long time.A. two another hours;costB. more two hours;spendsC. two hours more;paysD. another two hours;takes3. (2014内蒙古赤峰36)When did you have your school trip?.A. In five daysB. For five d
9、aysC. Twice a dayD. Five days ago4. (2013江苏南京)I dont believe that this boy can paint such a nice picture.A. five years oldB. five-years-oldC. five-year-oldD. five years old5. (2013云南)“Whats the English for 610?” “Its .”A. six tenB. ten sixC. ten to sixD. six past ten6. (2013山西)Li Jiacheng plans to g
10、ive of his money to the charity.Really? What a kind man he is!A. one thirdB. one threeC. one thirds7. (2013四川绵阳)There are teachers in our school, of them are women teachers.A. two hundreds;three fourthB. two hundred;three fourthsC. two hundred;three forths8. (2013天津)Nearly of the earth covered by se
11、a.A. three fourth;isB. three fourths;isC. three fourth;areD. 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
12、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。故选B。
