Learning to Accept

I learned how to accept life as it is from my father. However, he did not teach me acceptance(接受) when he was strong and healthy, but rather when he was 　1　 　and ill.

　 　My father was once a strong man who loved being active, but a terrible illness 　2　 　all that away. Now he can no longer walk, and he must sit quietly in a chair all day. Even talking is 　3　 　One night, I went to visit him with my sisters. We started talking about life, and I told them about one of my 　4　 . I said that we must very often give things up as we grow-our youth, our beauty, our friends-but it always 　5　 　that after we give something up, we gain something new in its place. Then suddenly my father 　6　 　up. He said, “But, Peter. I gave up 　7　 ! What did I gain?” I thought and thought, but I could not think of anything to say.　 8　 　, he answered his own question.

He could replace his great pain with a feeling of love for others, then I should be 　12　 　to give up my small irritations. In this 　13　 　, I learned the power of acceptance from my father.

35、(16分)将带电量为l×10^-8C的正电荷a，从无限远处的P点移到电场中的A点，要克服电场力做功1×10^-6J．若取无限远处为电势零点，问：

(1) 电荷a的电势能是增加还是减少? 电荷a在A点具有多少电势能?

(2) A点的电势是多少?　

(3) 若仅靠电场力可以把带电量为2×10^-8C的电荷b从无限远处移到电场中的A点，说明电荷b带正电还是带负电? 电场力做了多少功?
