A 把数字读出来或拼写出来时,如数字在三位或三位以上,应在十位数之前加上and,如无十位数时,则在百位数与个位数之间加上and:
713 seven hundred and thirteen
5,102 five thousand,one hundred and two
6,100 six thouand,one hundred(无十位数或个位数)
上述and的用法也适用于一千以上的数字,因为在英语中一万是ten thousand,十万是a hundred thousand:
320,410 three hundred and twenty thousand,four hundred and ten
上述方法同样适用于一百万以上的数字:
303,000,000 three hundred and three million
B hundred,thousand,million等单独使用或用于短语中,前面用a要比用one更常见:
100 a hundred
1,000 a thousand
100,000 a hundred thousand
我们也可以说a hundred and one,a hundred and two等及a hundred and ninety-nine和a thousand and one等,一直到a thousand and ninety-nine为止,或者用one而不用a(参见上面),因此:
1,040 a/one thousand and forty
但是:
1,140 one thousand,one hundred and forty
C hundred,thousand,million和dozen这些词用来指具体明确的数目时,不用复数形式:
six hundred men六百人
ten thousand pounds一万磅
two dozen eggs 24个鸡蛋
假如这些词用来指大致的计数,即只给人一个大致的概念时,必须用复数形式:
hundreds of people数以百计的人
thousands of birds成千上万的鸟
dozens of times数十次
注意:在这种情况下,要在数词hundreds,thousands等之后加上介词of。
of不能用在明确的数字之后,但在the/them/these/those之前或所有格之前则例外:
six of the blue ones六个蓝色的
ten of these这些中的十个
four of Toms brothers汤姆兄弟中的四个
D 由四个或四个以上的数码构成的数目,如上所示,是分成三位一组读写的,小数点(.)读为point:
10.92 ten point nine two
小数点后的零读为nought:
8.04 eight point nought four
但这个零也可读为o/+u/或zero。
