小升初语法讲解 数词（序数词） 专题训练（讲义） 牛津上海版（试用本）英语五年级下册 知识点讲解 序数词 第1~第10 第20~第90 第100 1st first 20th twentieth 100th hundredth 2nd second 30th thirtieth 3rd third 40th fortieth 4th fourth 50th fiftieth 5th fifth 60th sixtieth 6th sixth 70th seventieth 7th seventh 80th eightieth 8th eighth 90th ninetieth 9th ninth 10th tenth 注意： 序数词应注意的几点事项： 1. 多位数的基数词变成序数词时，只需将末位基数词变成序数词，前边的基数词不变。如： 42 forty-two 第42 forty-second 900 nine-hundred 第900 nine-hundredth 2. 当序数词用阿拉伯数字表示时，必须在数字后加上序数词的最后两个字母。如： 第21: 21st 第32: 32nd 3. 编了号的事物要用基数词表示顺序，但是基数词要后置。 例如： 第一课：Lesson One 第三十二页：Page 32 第305房间：Room 305 第12路公共汽车：Bus No.12 4. 序数词前一般要用定冠词the，如果序数词前用a或an时，则表示“又一；再一”（没有具体范围的限制）。 如：Though he had failed twice，he wanted to try a third time. 尽管他已失败了两次，他还想再试一次。 The little monkey had had three apples，and he wanted to eat a fourth one. 那只小猴子已经吃了3个苹果，他还想再吃一个。 精选精练 1．The Whites are from the _______ floor.
