数词用法的几个易错点

◆“一两天”之类的表达

“一两天”可说a day or two或one or two days。但不能说成 one day or two或a or two days。类似的有：a year or two / one or two years 一两年 / a month or two / one or two months。

◆“一个半”之类的表达

表示“一个半”可用a…and a half或one and a half… 如：

We waited for an hour and a half. / We waited for one and a half hours. 我们等了一个半小时。

◆“每隔几…”的表达法

如“每隔一天”的说法有every two days, every second day, every other day，“每隔3天”的说法有every three days或every third day。

◆“另外几…”的表达法

如“另加2个星期”可说another / a further two weeks或two other / more weeks。
