用法
The phrases a half, half of, and half a or half an are all correct, though they may differ slightly in meaning. For example, a half day is used when day has the special sense “a working day,” and the phrase then means “4 hours.” Half of a day and half a day are not restricted in this way and can mean either 4 or 12 hours.
短语a half,half of 和 half a 或者 half an 都是正确的, 尽管它们可能在意义上稍有不同。例如当day 当工作日来讲时, a half day 这个短语的意思是“四个小时”。 Half of a day 和 half a day 的意思不限于此, 它们可以表示四小时或者十二小时
