英语中时间的表达方法主要有直接法和借用介词法等。

八点正 eight o’clock
（2）借用介词法。

（3）表示正点的用法。

时间表示法和时段的简单运算是听力考试的热点，请看下面的对话：
W: How long does the class usually last?
M: Umm, let me think. It starts from a quarter to nine, and ends at nine thirty.
So...
W: That is fortyfive minutes. Thank you very much!
Q: When does the class usually start?
