黄金口诀
• 英语数词不难记,找出规则就容易。 一至十二词各异,一个一个单独记。 后面加teen变十几,thirteen, fifteen看仔细。 eighteen只有一个t,两个音节念清晰。 二十至九十后加ty,twenty不同重点记。 forty去掉字母u,thirty, fifty更出奇。 十位数后个位数,表示数值几十几. 按序排列不费力,连字符号莫丢弃。 巧学妙计加努力,hundred是你的好成绩
7.1000以上的数字,从后往前数每三位加一个逗号“,”第一 个逗号前为千(thousand),第二个逗号前为百万(million), 第三个逗号前为billion(十亿)。 英语中无“万”这个词,我们可以用“几十个千 (thousand)”表示几万,“几百个千(thousand)”表示 “几十万”。
特殊用法
1.数词作主语,谓语动词用单数。 Two months is quite a long time. Four and two is six. What‘s two and three?
2.一个半小时(一年半,一个半月可类推) one/an hour and a half one and a half hours
