数词的用法:
数词是指表示数目多少或顺序先后的词。表示数目多少的数词叫基数词,如 one, five, ten, thirty, sixty-five 等;表示顺序先后的数词叫序数词,如 first, sixth, tenth, twenty-first 等。数词用法相当于名词和形容词,在句中可用作主语、宾语、表语、定语、同位语等。
基数词
1. 英语中没有“万”这个读数单位,要表示汉语中的“万”,英语需借用thousand一词,如“一万”用“十个千”表示(ten thousand),“十万”用“一百个千”表示(one hundred thousand)。
2. 用作基数词单位的 hundred, thousand, million, billion 通常不带复数词尾-s,但若用于表示数百、数千、数百万这样的泛指,则用复数。
【例句】
About two thousand people died in the earthquake. 大约有两千人在地震中丧生。
Thousands of people go to the seaside every year. 每年成千上万的人到海滨去。
3. 表示整十的基数词用复数形式可以表示人的大约岁数或年代。
【例句】
He is in his early twenties. 他才二十出头。
This took place in the 1930s. 这事发生在20世纪30年代。
序数词
1. 许多序数词是由相应的基数词后加词尾-th构成的,如four / fourth,six / sixth,ten / tenth,sixteen / sixteenth,但是nine变为序数词是ninth,而不是nineth。
2. twentieth, thirtieth, fortieth 等表示整十的序数词,由相应的基数词将词尾y改为ie,再加-th 构成。
3. first, second, third 通常可缩写为1st, 2nd, 3rd。凡是以th结尾的序数词可缩写为“基数词+th”:4th, 5th, 9th, 11th, 60th, 128th等。
4. 非整十的多位数,将个位数变成序数词即可:twenty-first(第21),thirty-sixth(第36),ninety-ninth(第99),three hundred and sixty-fifth(第365)等。
5. hundred, thousand, million 等序数词形式为 hundredth, thousandth, millionth 等。
6. 序数词前通常要用定冠词,但表示考试或比赛等的名次时,通常可省略其前的定冠词。
【例句】
My room is on the second floor and his on the third. 我的房间在三楼,他的房间在四楼。
He was (the) third in the exam. 他考试得了第三名。

Counting before numbers
Before the invention of written numbers. people used many different ways to count things.
At first, people used their fingers,and even their toes. However,they could only count small numbers in this way.
After that. they began to make small marks on sticks and bones. This helped them count bigger numbers. They used them to count things like the days of the month,the amount of food and the number of animals they had.
Then people began to use tokens made from clay or small stones. This helped them count even bigger numbers. They often put the tokens on pieces of string so that they could carry them around easily. This developed into tools like the abacus.
Finally, people began to develop systems of written marks to show different numbers,and this led to the Hindu—Arabic system (0—9). We are still using this system today.
