一、基数词的表达方式

1.1-12, 独立成词。

5.101—999,三位数,百位与十位/个位之间加and。如:101-one hundred and one

6.1, 000以上数目,从右向左每三位用","分开,分别读为thousand , million, billion。

二、基数词的用法

1.hundred, thousand, million, billion的用法

用作基数词单位时,hundred, thousand, million, billion通常不带复数词尾s,不带of。如:six million;但若用于表示数百、数千、数百万、数十亿这样泛指的概念时,则用复数,并且后面 of。如:thousands of。

2.基数词表示时刻的用法

(1)顺读法----先时后分, "几点几分"。如:9:30 nine thirty。

(2)逆读法----先分后时 

A.表示"几点过几分",半小时以内,介词用past。读作:分钟数 past 钟点数。如:10:10 ten past ten。

B.表示"几点差几分",半小时以上,介词用to。读作:60减原分钟 to (钟点 1),即差几分到几点。如:7:40 twenty to eight。

C.15分钟:a quarter past 钟点/a quarter to (钟点 1)。如:3:15 a quarter past three,9:45 a quarter to ten。

D.30分钟:half past 钟点。如:12:30 half past twelve。

3."基数词 名词"的合成形容词作定语,中间用连字符"-", 当中的名词用单数。如:a seven-day holiday。

5.基数词表示编号的事物时,基数词首字母大写。如:Class Seven。

6.基数词作主语时,谓语动词用单数形式。如:Three and two is five.

三、序数词的表达方式

(1) 1-3, first, second, third。

(2) 4-19, 相应基数词 th。fifth, eighth, ninth, twelfth特殊记忆。

(3) 20-90, y变成i eth。如:twentieth。

(4)21-99, 只把个位的基数词变成序数词。如:twenty-first。

四、基数词变为序数词的口诀:

基变序,有规律,词尾加上th,

一、二、三特殊记,first,second,third,

八去"t",九去"e",

"ve"要让"f"替,

ty变成ti, 再加eth,

遇到几十几,只变个位就可以。

五、序数词的用法

1.序数词作定语,前面要加the。如:

The first truck is carrying a food basket.

John lives on the fifteenth floor.

*注意:如果序数词前面有形容词性物主代词或名词所有格修饰时,则不用定冠词the。如:my twelfth birthday。
