My grandparents can be good fun. They are retired, so they don't work anymore. My grandfather is
68 and my grandmother is 67, but they are not too old to be active. They exercise by playing golf and they
go out for meals and to the theater. Sometimes they take me out too. We have a good time. They also go on
great holidays Last year, they went to China and walked along the Great Wall!
Sometimes, my grandparents like to criticize me. They think that children today have an easy life. Life
was very different when they were young and there are many things about my life that they do not understand. They tell me, over and over, how they had to start work at 16. They know that I will go on to university and
won't be getting a job until I am about 22! They also think that I have too many possessions (财产), such as
mobile phones,computers and PSPs. When they were young, they did not have anything like that. What they
do not realize is that they cannot compare children at present time. They had the same kinds of things as the
rest of people of their age-so do I. It would be very strange if I only had the possessions that they had when
they were my age.

由电路图可知，当S闭合时，两电阻并联，电流表A1测R2支路的电流，电流表A2测干路电流； 并联电路中各支路两端的电压相等，∴根据欧姆定律可得：IR1IR2=UR1UR2=R2R1=6Ω4Ω=32， 并联电路中干路电流等于各支路电...
