某市电价为一个自然月内用电量在100度以内的每度电0.5元,在101度到200度之间的每度电1元,在201度以上的每度电2元。张先生家第三季度缴纳电费370元,该季度用电最多的月份用电量不超过用电最少月份的2倍,问他第三季度最少用了多少度电

A.300

B.420

C.480

D.512

答案

参考答案:C

解析:解析:要使用电量最少,则应让用的超过200度的电尽可能多,则两个用电少的月份用电量相同,设为x。根据题意有:[50+1×(x-100)]×2+50+100+2×(2x-200)=370,x=120,总用电量为4x=480。

Recently I gave my adult students homework. It was “go to someone you love and tell them you love them.” It has to be someone you have never said those words to before or at least haven’t shared those words with for a long time.

It sounds like very tough homework since most of the men were over 35 and were raised in the generation of men that were taught expressing emotions is not “macho (阳刚之气).” Showing feelings or crying was just not done. So this was very threatening homework for some.

At the beginning of our next class, I asked if someone wanted to share what happened when they told someone they loved them. I fully expected one of the women to volunteer, as was usually the case, but on this evening one of the men raised his hand, quite moved and a bit shaken.

As he unfolded out of his chair (all 1.85 meters of him), he began by saying, “Dennis, I was quite angry with you last week when you gave us this homework. Who were you to tell me to do something that personal?”

“But as I began driving home my conscience (良心)started telling me that I knew exactly who I needed to say ‘I love you’ to.”

“Five years ago, my father and I had a severe disagreement and really never settled it since then. We avoided seeing each other unless we absolutely had to at Christmas or other family gatherings. But even then, we hardly spoke to each other.”

“So last Tuesday by the time I got home I had convinced myself. I was going to tell my father I loved him. It’s strange, but just making that decision seemed to lift a heavy load off my chest.
