sunny days前用什么介词

用on...

认识介词 in,on,at

(一)介词in,on和at表示时间

年、季、月、周要用in,日期、节气用on行;

某时某刻用at,at the age of表年龄;

圣诞、夜晚、钟点前,用上at才自然;

早、午、晚上常用in,固定短语记心间.

(1)at主要表示:

①在某个具体时间,如:在……时刻,在……点钟,at seven o'clock,at 9:30等

②固定短语:at night,at noon,at that time,at the age of,at the weekend,at Christmas等

(2)on用来表示“在……天”,如:on Sunday,on the following day,on October 1,1949等

(3)in用来表示:

①在某年、某季、某月、某周,如:in 2003,in summer,in September,in the 10th week等

②在一段时间之后(之内),如:in a few days,in a minute,in two weeks等

③用在“早晨/上午、下午、晚上”名词前,如:

in the morning,in the afternoon,in the evening

如果表示某一天的上午、下午和晚上,要用介词on.如:on Sunday morning,on Saturday evening

可巧记为:某天上下午和晚上,不能用in要用on.

(二)介词in,on和at表示地点

on“在……之上”接触面,“靠近、接壤”左右边;

in“在里面”和“中间”,也可表示在“大地点”;

at表示在“小地点”,“入口、车站、影剧院”;

home前有限定“冠”,须用in把at换;

“夜间、车辆”若有限(定词),“回家途中”on在前.

(1)on表示“在……之上”(与物体表面相接触).如:

His pen is on his desk.

表示“靠近;相互接壤”,以及在左、右边都用on.如:

Korea lies on the northeast of China.

Tom sits on my right.

(2)in表示“在……里面”(物体内部)、“在……中间”.如:

My pen is in my pencil-box.

in还可以表示“在大地点”.如:

They live in Shanghai while we live in Beijing.

(3)at表示在较小的地点,在“入口、车站”和“影剧院”等名词前也用at.如:

at the entrance to the library,at the bus stop,at the theatre,at the cinema

(4)home前一般用at,但若有物主代词或定冠词等定语修饰时,必须用in.如:

at home,in my home,in his simple home(在他简朴的家中)

(5)“夜间”(night)、“车辆”(bus,bike,train等)名词前若有限定词修饰,以及“在……途中”用介词on.如:
