(一)表示时间的介词 (1)at,on,in

①表示时间“点”用at。例如:at seven,at noon等。有时表示不确定的时间和短期假日的名词之前也可用at。如at that time,at night等。例如:

—When did Mr.Green come here? —At nine o'clock yesterday morning. Wu Yin gets up at six o'clock every day.

②表示时间“段”用on或in,一般说来,在某一天用on。如on Monday,on June 1st;指在一段时间内(年、月、日等)用in。如in the morning,in a week,in summer,in 1999,in October等。例如:

Mrs Brown came to China in 1996. ③表示某天的morning,afternoon,evening时用on。如果在morning,afternoon,evening之前有形容词修饰也用on。例如:

①during表示某一特定的一段时间,通常与一般过去时连用。例如: She woke many times during the night.

②for表示好长一段时间,指时间上的延续。例如: My uncle has worked in this hospital for ten years.

③since后接时间的起点,其终点往往是现在,常与完成时连用。例如: I haven't seen you since last Saturday. Tom has worked here since two years ago.

He has been late for school three times since the morning of last Friday. (3)after,in

这两个介词都可表示时间,意为“在……以后”。它们的区别是: after以过去为起点,表示过去的一段时间之后,通常用于过去的时态;in以现在为起点,表示将来一段时间之后,常用于将来的时态。例如:

After gratuation,he went to Japan. The teacher will be back in an hour. (二)表示地点、位置的介词

Hainan lies to the south of Guangdong. (2)above,over,on

这三个词都表示一个物体高于另一个物体,可译作“在……上面”。above表示位置高于某物,在其上方,但不是正上方。它的反义词是below;over表示在正上方,指垂直方向,它的反义词是under; on指两个物体表面接触,一个在另一个的上面。例如:

Let me show you the place on the map. The water came above our knees. A lamp was hanging over the table.
