I knew a guy who played his radio only in the morning.


When someone asked him why,he replied, "This is an AM radio."


 


 


Notes 1:


 


1. I knew a guy who played his radio only in the morning.


 


我认识一个人,他只在早上收听广播。


 


2. When someone asked him why,he replied, "This is an AM radio."


 


当有人问他为什么时,他回答:“(我的)这一台是AM(调幅)收音机。


 


"AM"表示“调幅”(amplitude modulation),也可表示“上午的”,通常与时间连用,不需再加o'clok,也可以用"a.m."表示,如:at 9 a.m.(在早上九点)。广播的收听方式有调幅 (AM)和调频(FM/frequency modulation)两种。


 


那个拥有AM收音机的人认为AM是早上的意思,所以只能在早上收听。


 


amplitude [ˈæmplɪtju:d] n.(物理)振幅


 


modulaiion [ˌmɒdjʊ'leɪʃn] n.(电子)电波频率的调变;调幅


 


frequency [ˈfri:kwənsi] n.(物理)频率
