sunny days前用什么介词

1个回答

  • 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:

    He was at home on the night of May 1.

    Jim often goes to school on his bike.
