英语语法：half的用法

‍前几期我们学习了英语语法：基数词和序数词1-19、基数词和序数词20-99、基数词和序数词100-1,000,000、分数词。这一期，我们学习英语语法：half的用法。

数词

5.3 half的用法

“half a(an)+名词”或“a half+名词”表示“一半……”。

比如：

半小时

half anhour

a half hour

半天

half a day

a half day

半公里

half akilometer

a halfkilometer

half充当名词时，可以用在结构“half of…”中，也可以略去of。但half用在人称代词前面时，of不能省略。

比如：

half (of)the cars

一半的汽车

half (of)the work

一半的工作

half of us

我们中的一半人

“一个半”的表示如下：

一个半小时

an hour anda half

one and ahalf hours

1.5公斤

akilogramme and a half

one and ahalf kilogrammes
