在平时的学习中,我们注意到一般的时间状语前都有介词in/on/at或for 等,而实际上在英语中,有不少表示时间的状语前是不加介词的. 现我将几种情况加以小结,供同学们在学习中参考.

我们今天上了六节课.
3) We had a good time the day before yesterday.

前面往往不加介词.例如:
1) That morning he got up very early.
那天早上他起得很早.
2) What are you busy with these days?
这几天你在忙些什么?
3) We will have a big gathering this coming Saturday.
下星期六我们将进行一次大聚会.
3.由next, last, the next, the last 等用于表示时间概念的名词前时,前面不用介词修饰.例如：
1) We planted many trees last spring.
去年春天我们栽了许多树.
2) She said she would pay a trip to Suzhou the next month.
他说他下个月将去苏州.
3) The very next time I saw her, she was working in London.
在那次之后我又见到他时,他正在伦敦工作.
4.在each, any, every, some, all 等用于表示时间概念的名词前,一般不用介词来修饰. 例如:
1) The buses go every 10 minutes.
汽车每隔10分钟一辆.
2) Jack coughed all night.
杰克咳了一整夜.
