数词的基本用法   

(一)基数词的基本用法   

1.定语

2.主语   

数词作主语,谓语动词用单数。   

如: Two months is quite a long time.   

Five is an odd number.   

3.宾语或介词宾语

4.表语

Five plus seven is twelve.   

5.同位语

Is there room for us two?   

6.基数词+单数名词+形容词构成合成形容词。如:一个五岁的男孩a five-year-old boy;一座800米长的桥an 800-metre-long bridge;女子400米接力girls‘400-metre relay race.   

7.句型:主语+is +about(大约)/ over =more than(超过)/nearly(接近)+具体数词+metre(s)/kilometre(s)/kilo(s)long / high /tall /deep /away等。如:长江长6300公里。   

The Changjiang River is 6,300 kilometres long.   

8.表示“……十”的数词的复数形式可以用来表示人的岁数或年代:   

He is in his early thirties.   

He died still in his forties.   

This took place in the 1930s.   

(二)序数词的基本用法   

1.序数词主要用作定语,前面一般要加定冠词(或物主代词):   

Tom is their second son.   

They celebrated the 10th anniversary of the founding of the republic.   

I will never give up,not even on the 1,000th or 10,000th try.   

2.有时前面可以加一个不定冠词来表示“再一”,“又一”这样的意思:   

We‘ll have to do it a second time.   

Shall I ask him a third time?   

When I sat down,a fourth man rose to speak.   

3.First,second 等有时可用来表示“先进个人(批)”“第二个人”等:   

She was among the first to come and settle in Dujiashan.   

You will be the second to speak.   

4.如果数字较长,序数词总避免使用,而且读的方法也常常简化:   

第201房间:Room 201   

第319面:page 319   

先进拖拉机厂:the Number I Tractor Works   

第六号车厢:Carriage No.6
