1、中考英语第二轮复习专项训练学案单项选择 数词2019年中考英语第二轮复习专项训练学案(单项选择数词)一、基数词（一）基数词的基本形式1. 112是基本的数词。2. 1319是在39后分别加上teen，注意13(thirteen)和15 (fifteen)的拼法。3. 20、30、4jD、50、60、70、80和90是由相应的个位数+ty构成，注意20、30、40、50和80的拼法。4.2199中除整十外的数字是由十位数加个位数构成，中间由连字符连接。如：21twenty-one35thirty-five44forty-four55fifty-five88eighty-eight99ninety

2、-nine。5. 101999由百位数与上面的两位数合起来构成，在百位数和十位数之间要加and。如果十位数是零，则在个位数前加and。6.千位数字只要在百位数前加上千位数，在百位和千位之间不加任何词或符号。如果百位数是零，则在千位数后加and。如：1, 348one thousand three hundred and forty-eight5,076five thousand and seventy-six2,006two thousand and six。7.万位以上数字的读法：以分号为单位（由后向前，三位数加一个分号），第一个分号前是千(thousand)，第二个分号前是百万(milli

3、on)，第三个分号前是十亿(billion)。如：423，845，208，172four hundred and twenty-three billion, eight hundred and forty-five million,two hundred and eight thousand, one hundred and seventy-two。注意：在表示“几百；几千；几百万”等确切的数字时，直接用基数词+hundred/thousand/million;表示“成百；数千；上百万”等不确切的数字时，则用hundreds/thousands/millions of表达。（二）日期、时间、编

4、号、年龄等的用法1. “数词十单数名词”相当于合成形容词作定语。如：a three-year-old girl一个3岁大的女孩2. “整十”的基数词的复数形式可用于表示几十年代或在某人几十多岁时。如：in the 1990s在20世纪90年代in his twenties在他20多岁时3.“another+基数词十名词复数”或“基数词+more+名词”表示在已有基础上再增加一定的数量。如：another two cakes= two more cakes再增加两块蛋糕4. “一两天”可表达为：a day or two或one or two days。有关“半”的表达：half an hour，

5、“半小时”;three years and a half= three and a half years,“三年半”。5.表示编号时，用“单数名词十基数词”，名词的第一个字母通常要大写。如：Class Two二班Room 1212号房间No.1 Middle School第一中学Lesson One第一课Page 10第10页例题1How do you say the number 567,043?第1页Afive hundred sixty-seven thousand forty-threeB. five hundred sixty-seven thousand and forty-thr

6、eeCfive hundred and sixty-seven thousand forty-threeD. five hundred and sixty-seven thousand and forty-three【解祈】D本题考查了万位数以上的数字读法。分号前用千“thousand”表达，且百位数和十位数之间要加and，分号后百位数是零，仍需加and。故选D项。例题2一What“s five and seven?-Its _.A. twelveB. twentyC. thirty-five【解析】A本题考查基数的词义辨析。句意：五加七等于几？十二。故选A。例题3It is reported

7、 that nearly _foreign kids joined a British boarding schoollast year, and a third of them came from China.A. nine thousandB. nine thousandsC. nine thousand ofD.nine thousands of【解析】A本题考查大数字词的表达形式。当thousand等大数字名词前有基数词修饰时，不可以用复数，而C答案of后面应表示特指，故选择A。二、序数词序数词的构成：1. “第一( first)”、“第二(second)”和“第三(third)”与其

8、基数词形式无关，“第四”至“第十”是在与之相应的基数词后加th，但要注意“第五”、“第八”、“第九”的拼法。2.序数词第11第19是在原基数词词尾加th，注意第十二的拼法。3. 2090的整十位数的序数词是将其相应的基数词词尾ty改为tieth。4. 21以上的序数词是将个位数改成序数词。如：第二十一twenty- first第五十四fifty-fourth第一百四十二one hundred and forty-second。注意：1.序数词表示顺序时，其前要加定冠词the，其后接单数名词。如：the second picture。2.序数词前也可用不定冠词a( an)，表示“再；又。”如：I

9、“ve tried twice, but I“ll try a third time.我已试过两次了，但我将再试一次。例题1Thereare_syllables（音节）inthewordrecommend.Andthestress(重音)falls on the _-syllable.A. two, secondB. three, firstC. three, thirdD. three, second【解析】C句意：单词recommend有三个音节，重音落在第三个音节上。第一空用基数词three，第二空用序数词third。故选C项。例题2一Do you know the girls who

10、are in the living room?-Yes, they are my classmates. They are celebrating Lucy“s _ birthday.A. thirteenB. the thirteenthC. thirteenth【解析】C本题考查数词的辨析。thirteen为基数词，表数量，thirteenth为序数词，表顺序。句意：你认识客厅里那些女孩吗？认识，她们是我同学，她们在庆祝露西的十三岁生日。这里应用序数词，而序数词前有了Lucy“s，所以不能用the修饰。故选C。例题3David Beckham has _ children. Brookly

11、n Beckham is his_ son.第2页A. third; firstB. three; oneC. three; firstD. third; one【解析】C句意：贝克汉姆有3个孩子，Brooklyn是他的第一个儿子。前一空选基数词three，后一空用序数词first。故选C。三、分数1.分数的构成：分子用基数词，分母用序数词；如果分子大于1，分母要用复数形式。如：。在英语中“四分之一”常表示为a quarter；“四分之三”表示为three quarters；“二分之一”表示为a half。2.分数的用法：“分数+of+限定词十名词复数”作主语时，谓语动词应用复数形式。如：On

12、e half of the students are from America in this school.这所学校有一半学生来自美国。“分数+of+限定词十不可数名词名词单数”作主语时，谓语动词应用第三人称单数形式。如：Two thirds of her money was spent on clothes.她把三分之二的钱花在了衣服上。3.百分数的表达方式是：基数词+percent。如：thirty percent of the students30%的学生。例题1一Mum，_ of the apples _gone bad.- We“d better eat up the rest a

13、s soon as possible.A. one third; haveB. one third; hasC. one three; haveD. first three; has【解析】A本题前一空考查分数。分数的构成是分子用基数词，分母用序数词；后一空考查主谓一致，主语“分数+oftheapples”是复数，相应的谓语动词用复数形式。故选A项。例题2_of the girls will join the summer camp to visit England.A. Three fivesB. Third fifthsC. Three fifths【解析】C本题考查分数的词的构成。词义为

14、“五分之三”，分子用基数词three，分母用序数词fifth，由于分子大于一，所以fifth要加一s，即用fifths。故选C。例题3It“s said that _ of the water around the world_ polluted.A. two thirds; hasB. two thirds; isC. two third; areD. two thirds; have【解析】B本题考查分数词的用法及被动语态结构。句意：据说世界上三分之二的水被污染了。第一空用two thirds，由于分词修饰的名词water为不可数名词，动词用三单形式，水被污染，动词用被动语态，故选B。真题
