on的用法比较中性,后面一般用weekend
on,at,in用法巧记
on,at,in这三个常用介词都可以表示时间和地点,但具体用法不同,多数学生对它们混淆不清.现在只要记住了口诀,就可避免at,on,in的种种误用.
1. on,in,at表示时间
on“在具体某一天”①
“当某时”,动名词, arrival,death前;early,late位句先②,用in一般“上”“下”“晚”;on用于天,in用于月、季、年③;限定三时in要变.④at是个时间点,“工作”“时刻”与“圣诞”⑤.at noon(night),in the day,习惯用语记心间.
注:①on表示在具体某一天及具体某一天的上午、下午和晚上.

wish you success(祝你成功)
