中考总复ä¹

1. 中考总复习 数词 龙田镇初级中学: 杨 笠

2. [目 标]： 1、要求学生再次熟记数词（ 基数词和序数词），特别是的序数词 2、掌握数词的运用 [重 点]：1、熟记特殊的序数词 2、数词的运用 [课 时]：1课时

3. 数词定义: 数词就是表示事物的数量和顺序的词，分基数词和序数词两种。 数词的分类: ｛ 基数词 序数词

4. 一.基数词 表示数量多少的词是基数词，如：one, two, three等。构成方法如下： 1）从1－12分别由从one到twelve12个各不相同的词表示。 2）从13－19均以后缀-teen结尾。 3）从20－90的整十数词均以后缀-ty结尾。表示“几十几”时，个位和十位之间需加连字符，如twenty-one, thirty-two, forty-three等。 4）数字的写法和读法： A 十位与个位之间要加连字符“-”； B百位和十位之间要加and；

5. C三位数以上的数，从个位往前数，每三位数加一个逗号“，”，从后往前数的第一个逗号代表thousand,第二个逗号代表million,第三个逗号是billion，注意这几个词此时不能用复数形式，其后也不能加and。5）表示具体、准确的数目时，hundred, thousand, million等数词后不能加-s,如:five hundred, six thousand, seven million等。6）当hundred, thousand等数词与of连用，表示不具体、不准确的数目时，词尾须加-s。如：thousands of students, millions of trees.

6. 一二三要牢记， [序数词口诀] 八去t，九去e； 五和十二两兄弟，常用f代ve, 变换整十要注意，要把y变ie,然后再加th. (first second third) (eight-eighth nine-ninth) (five-fifth twelve-twelfth) (twenty-twentieth forth-forth) 二.序数词 1）不规则变化 2）以-ty结尾的表示“几十”的基数词，先把y变为i，再加-eth 3）表示“第几十几”时，十位数的“几十”仍用基数词，只把个位部分变成序数词就行了。 4）除上述情况外，均在词尾加-th，如ten tenth onehundred one hundredth

7. 三. 数词的用法 • （一）表示事物的编号 • 基数词放到名词的后边,该名词一般要大写；序数词放到名词的前面，加定冠词。 • 第一课 Lesson 1/ the first lesson. Row 3/ the third row • （二）年、日、时刻表达方法。 • “年”用基数词，“日”用序数词，前要加定冠词。读的顺序是月日年。如：1999年5月2日读作：May the second, nineteen ninety。

8. “时刻”用基数词表达，同时要注意以下两点。“时刻”用基数词表达，同时要注意以下两点。 • 1.表示“整点”时，在基数词后加o’clock; 9:00 o’clock. • 2. 分钟数小于或等于30分钟的，用“分钟数＋past＋钟点数”形式； 分钟数大于30分钟的，用“到下一个钟点所差的分钟数＋to＋下一个钟点数”形式,也可以依次读钟点数和分钟数。 7:20 twenty past seven或seven twenty. • 3.注意两个特殊的表示时间的单位词：30分钟用half，15分钟用a quarter，如： 6:30 读作：half past six 5:45 读作：a quarter to six 6:15 读作：a quarter past six

9. （三）分数的表达方法 • 表示分数时，分子用基数，分母用序数，分子大于1，分母用复数。分数修饰名词时，后用of短语。如： 1/3 one third of teachers 3/7 three sevenths of the boys 1/2, 1/4分别用 a half和a quarter表示。

10. （四）“基数词－名词－形容词”结构 • “基数词－名词－形容词”只能用来放到名词前作定语。如： She is a 3-year-old girl. They live in a 7-storey-high building. • 注：这种结构中名词不能用复数，同时只能作定语。用作表语时，不用连字符，名词有复数。如： Tony is 10 years old this year. Tony is a 10-year-old boy.

11. 中考考什么? • 中考从以下几个方面来考查学生对数词的掌握情况：

13. 2.分数 A It is said that the gravity(引力) on Mars is only about __________ of the gravity on earth. • A. three－eighths B. third－eighth • C. three－eights D. third－eight • [解题技巧] • 以此立意的试题考查考生能否正确使用分数：分子在前用基数，分母在后用序数。分子大于一，分母用复数，分子与分母之间可以用连字符连起来也可以不用连字符，如two thirds或two-thirds；当分数修饰名词作定语时，后要跟of，如：two thirds of students 三分之二的学生 • 本题的选项中只有A项正确。

14. 3. hundred,thousand,million,billion等单位数词 • －How many people will come to Beijing next year? • －It’s hard to say, ________ people, I think. • A. million of B. millions of C. three millions • D. three millions of • [解题技巧] • 以此立意的试题考查考生能否正确使用hundred等单位数词。表示单位的数词用法分两种情况：1）当放在具体的数字后边，表示具体的“百、千、百万、十亿”时，不能用复数形式，可以直接修饰名词复数，如two thousand students；2）当表示大概的“几百、几千、几百万、几十亿”时，用“复数形式＋of”结构，前边不能用具体的数字，如：thousands of students。 • 本题中只有B项正确。 B
