用英语表达数字可能会让学生和听力者感到困惑。遵循以下规则,确保你理解了如何用英语口语表达数字。
下面列出的数字是为了帮助学习正确的英语分组。一般来说,大于 9 的数字应始终用英文书写的数字表示,而小于 10 的数字则应写出:
I have 15 clients in New York.
He ate three cookies.
She has 240 contacts on her mailing list.
1到100的数字怎么说
比如1到20之间的单个数字。在那之后,用十位数(20、30等)后跟着是数字1到9:
7 - seven
19 - nineteen
32 - thirty-two
89 - eighty-nine
当表达大数字(超过100)时,以百为单位阅读。顺序是:十亿、百万、千、百。注意百位、千位等等后面不能加"s ":
200 is two hundred NOT two hundreds
如何说百位数字
以百开头,从1到9,再加上“百”。最后说最后两位数:
350 – three hundred fifty
425 – four hundred twenty-five
873 - eight hundred seventy-three
112 - one hundred twelve
注意:英式英语在“hundred”后面加“and”。美式英语省略“and”
如何说千位数字
说出一个999以内的数字,后面跟着“thousand”。
15,560 – fifteen thousand five hundred sixty
786,450 – seven hundred six thousand four hundred fifty
342,713 - three hundred forty-two thousand seven hundred thirteen
569,045 - five hundred sixty-nine thousand forty-five
如何说出数百万数字
对于“百万”,可以用999以下的数字加上“million”。结束时先说千,然后说百.
2,450,000 – two million four hundred fifty thousand
27,805,234 - twenty-seven million eight hundred five thousands two hundred thirty-four
934,700,000 – nine hundred thirty-four million seven hundred thousand
589,432,420 - five hundred eighty-nine million four hundred thirty-two thousand four hundred twenty
对于更大的数字,首先使用数十亿,然后以类似于数百万的方式使用万亿:
23,870,550,000 - twenty-three billion eight hundred seventy million five hundred fifty thousand
12,600,450,345,000 - twelve trillion six hundred billion four hundred fifty million three hundred forty-five thousand
大数字通常四舍五入到下一个最大或下一个最小的数字, 例如,345,987,650 四舍五入为 350,000,000
