引导时间状语的介词in/on/at/during/till与until
1、用in的时间短语有：
① 表示一天中的某段时间：in the morning；in the afternoon；in the evening
② 表示周、月份、年份：in a week；in January；in Feb；in 1992
③ 表示季节：in summer；in spring；in autumn；in winter
in+表示时间长度的短语可以表示“在某段时间之内”,这时可以与现在时、过去时或将来时连用,一般与完成某动作有关；还可译为“……时间之后”,一般与将来时连用.根据时态判别in 表示的含义
in twenty minutes' time 20分钟之后
We will finish class in half an hour.
2、用on的时间短语有：
① 表示星期：on Monday；on Friday
② 表示日期：on June 1st；on 23rd March（在书写日期时没有冠词,但在口语中则分别读为：on June the first；on the 23rd of March）
