in后面跟时间段，表示在一段时间里技巧:in通常接的时间范围大(一天以上)多是月份、季节、年等比如 In May， In summer等n搭配星期几或具体日期指在某一天或某具体一天的上午，下午，晚上，如: n Mnday ,n Sunday afternn, n July 1, 1999
at后常跟一天内具体的时间点般表示点时间，如at six 'clck, at three thirty习惯用法: at night， at nn
固定搭配at nn/night中午/晚上in the mrning/afternn/evening早上/下午/晚上但是，当这些名词有前缀时，介词则用n，如: n Wednesday evening)
n表示在具体的某一天，或某一天的上下午等，技巧:看这一天或上下午“是否受到修饰限定”如果是，则用n，这个限定成分，可以在前，也可以在后例子：On a very ht mrning, we went t the swimming，在一个很热的上午我们去了游泳池
注意在英语中，如果时间名词前用this，last，next等修饰时，像这样的表示，“在某时”的时间短语前，并不需要任何介词。例如:last mnth, last week, this year, this week, the next day, the next year等。
