在测量电流互感器极性时，电池正极接一次侧正极，负极接一次侧负极，在二次侧接直流电流表，如何判断二次侧的正极（）
A、电池断开时，表针向正方向转，则与表正极相连的是二次侧正极
B、电池接通时，表针向正方向转，则与表正极相连的是二次侧正极
C、电池断开时，表针向反方向转，则与表负极相连的是二次侧正极
D、电池接通时，表针向反方向转，则与表负极相连的是二次侧正极
参考答案：B
Around twenty years ago I was living in York. ___ I had a lot of experience and a Master’s degree, I could not find ____ work. I was ____ a school bus to make ends meet（使收支相抵）and ____ with a friend of mine, for I had lost my flat. I had ____ five interviews with a company and one day between bus runs they called to say I did not ___ the job. “Why has my life become so ____?” I thought painfully. As I pulled the bus over to ___ a little girl, she handed me an earring ____ I should keep it ___ somebody claimed it. The earring was painted black and said “BE HAPPY”. At first I got angry. Then it ____ me -- I had been giving all of my ____ to what was going wrong with my ____ rather than what was right! I decided then and there to make a ____ of fifty things I was happy with. Later, I decided to ____ more things to the list. That night there was a phone call for ____ from a lady who was a director at a larger ____. She asked me if I would ___ a one-day lecture on stress (压力) management to 200 medical workers. I said yes. My ____ there went very well, and before long I got a well-paid job. To this day I know that it was because I changed my way of ____ that I completely changed my life.
