Give me two, please. 桌子上有许多苹果,请给我两个。(作宾语) I think his father is forty years old. 我想他父亲四十岁了。(作定语) ★用于名词之后表示顺序。例如: Lesson One is very easy. 第一课很容易。 Please open your books and turn to page 28. 请打开课本翻到二十八页。 ★基数词可表示年份、时间(钟点)、电话号码、年龄等。例如: I was born on July 12, 1989. 我生于1989年7月12 日。 —What’s the time? 几点了? —It’s nine thirty. 九点三十分。 His telephone number is 3940530. 他的电话号码是3940530。 —How old are you? 你多大了? —I’m forty-five. 我四十五岁了。 He has two uncles, and I have only one. 他有两个叔叔,我只有一个。 There are fifty-six students in our class. 我们班上有五十六个学生。 ▲难点 表示“数以百计”、“数以千计”,分别用hundreds of, thousands of,且它们前面不可加入任何具体数词。也就是说hundred, thousand 前有具体数词时,其后不能加-s,当hundred, thousand 与介词of 连用时,则用复数形式,表示不确定的数目,其前不能有数词。例如: There are hundreds of foreign students in their school. 他们学校有数百名外国学生。 根据汉语意思完成下列句子。 1. 一年有三百六十五天。 There are ________ days in a year. 2. 这家商店里有数百台电视。 There are ________ TV sets in this shop. 3. 一小时有三千六百秒钟。 There are ________ seconds (秒) in an hour. 4. 我每天早上五点半起床。 I get up at ________ every morning. 5. 我们班有四十八套桌椅。 There are ________ desks and chairs in our class. 参考答案: 1. three hundred and sixty-five 2. hundreds of 3. three thousand six hundred 4. five thirty / thirty past five / half past five 5. forty-eight (文/孙广所;英语通初一版04~05学年第12期;版权归英语辅导报社所有,独家网络合作伙伴新浪教育,未经许可,不得以任何形式进行转载。) |
