　　初中的物理学到初三电学的时候，我们就会触摸到电压表这个玩意。要想有效地掌握到电压表，我们就要做到以下三点：　　一、电压表是干什么的？　　电压表便是一个工具，一个测量电压的工具。测电压不像测电流，测电流是说测电路中的电流，而测电压是说测某段电路两头的电压。从这个描述上我们就要区分它和电流表！　　电压表的结构为：在灵敏电流计里面有一个永磁体，在电流计的两个接线柱之间串联一个由导线构成的线圈，线圈放置在永磁体的磁场中，并经过传动装置与表的指针相连。　　换种说法我们能够这样了解电压表是用电流表串联一个电阻很大的电阻构成的。我们能够猜想到电压表的内阻很大，接入电路后电流十分小，相当于断路！　　二、正

Happy Teacher's DayIt is Teachers' Day on September 10th every year. Teachers are the greatest people in the world, I think, because they teach us how to write and read. The most important is that they teach us how to be a real man. They are also kind to everybody and they don't want anyone to fall
