用英语是: one(1) two(2) three(3) four (4) five(5) six (6) seven(7)。英语中纯数字的表达方法小数和分数:0.17 zero point one seven / point seventeen / zero point seventeen1/2 one half1/3 one /a third3/4 three fourths7'2/ 5seven and two fifths大于100的数字:101 one hundred (and ) one200 two hundred998 nine hundred ( and ) ninety'eight在英语中上面括弧中的and一般不能省略;而在美国英语中却往往省去。请分析下面的对话:A:How many people are present in the party last night?B: That‘s nine hundred and ninety-eight, exactly.A: Woo, you must be joking. How can you get such an accurate number?B: Ha, ha…… surely I am joking. You silly goose.大于1000的数字:1001 a/one thousand (and) one2232 two thousand two hundred (and) thirty'two900,732,266,043nine hundred billion seven hundred thirty'two million two hundred sixty'six thousand and forty three英语中一千以上数字的表达方法是以三位数为单元,从高到低billion,million,thousand而依次读出的。因此我们在听时,可以三位数三位数地记录。试比较下面的对话:A:Can you tell me exactly the numbers of the whole people in our country?B:One billion four hundred thirty'two million two hundred sixty'six thousand and forty three.A:Thank you very much.
1/2 可以读为one half 或 one over two。1/2 的说法跟 1/3、1/4 都不一样, 它不读为onesecond,而要用 one half。
而 one of two 常用在数学上, 强调 1 除以 2, 这种说法在日常生活中用得比较少。至于1/3是one third,1/4 是 one fourth等,大家对这种说法都已经很熟悉了,在此不多说,但要注意两点:在日常生活中,用 onequarter 表示1/4比用 one fourth 更多一些。
