‎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. 1～12是基本的数词。‎ ‎ 2. 13～19是在3～9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. 21～99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：21→twenty-one 35→thirty-five 44→forty-four 55→fifty-five 88 →eighty-eight 99→ ninety-nine。‎ ‎ 5. 101～999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, 348→one thousand three hundred and forty-eight 5,076→five thousand and seventy-six 2,006→ two 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(million)，第三个分号前是十亿( billion)。如：423，845，208，172→four 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，“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 12 12号房间 No.1 Middle School第一中学 ‎ Lesson One 第一课 Page 10 第10页 ‎ 例题1 How do you say the number 567,043?‎ ‎ A five hundred sixty-seven thousand forty-three ‎ B. five hundred sixty-seven thousand and forty-three ‎ C five hundred and sixty-seven thousand forty-three ‎ D. 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? ---It’s _______________.‎ ‎ A. twelve B. twenty C. 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3 It is reported that nearly ________foreign kids joined a British boarding school last year, and a third of them came from China.‎ ‎ A. nine thousand B. nine thousands C. nine thousand of D.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. 20～90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'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1 There are _______ syllables（音节）in the word recommend. And the stress(重音)falls on the ____________-syllable.‎ ‎ A. two, second B. three, first C. three, third D. 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 are in the living room?‎ ‎ ---Yes, they are my classmates. They are celebrating Lucy's ________ birthday.‎ ‎ A. thirteen B. the thirteenth C. 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3 ‎ David Beckham has ______ children. Brooklyn Beckham is his _________ son.‎ ‎ A. third; first B. three; one C. three; first D. 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：‎ ‎ 1/2 o ne-second; 3/4 three-fourths; 2/5 two- fifths。‎ ‎ 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：‎ ‎ One 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 students 30%的学生。‎ ‎ 例题1 一Mum，________ of the apples __________gone bad.‎ ‎ --- We'd better eat up the rest as soon as possible.‎ ‎ A. one third; have B. one third; has C. one three; have D. 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+of the apples”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 fives B. Third fifths C. Three fifths ‎ 【解析】C本题考查分数的词的构成。词义为“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3 It's said that ________ of the water around the world______ polluted.‎ ‎ A. two thirds; has B. two thirds; is C. two third; are D. 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。‎ 真题测试 测试时间：15分钟 满分：30分 ‎1.
