I teach economics at UNLV three times per week. Last Monday, at the beginning of class, I31asked my students how their weekend had been. One young man said that his weekend had not been so good. He had his wisdom teeth32. The young man then proceeded to ask me why I33seemed to be so cheerful.

His question34me of something I’d read somewhere before:“Every morning when you get up, you have a choice about how you want to35life that day,” I said.“I choose to be cheerful.”

“Let me give you a(n)36,” I continued,37all sixty students in the class.“In addition to teaching here at UNLV, I also teach at the community college in Henderson, 17 miles down the freeway from where I live. One day a few weeks ago I drove to Henderson. I38the freeway and turned onto College Drive. I only had to drive another quarter mile down the road to the college. But just then my car39. I tried to start it again, but the engine wouldn’t40. So I put my flashers on, grabbed my books, and41down the road to the college.”

“As soon as I got there I called AAA(汽车协会) and42for a tow truck to meet me at my car after class. The secretary in the Provost’s office asked me what had happened.‘This is my43day,’ I replied, smiling.”

“‘But your car breaks down.’ She was puzzled.‘What do you mean?’”

“‘I live 17 miles from here.’ I replied.‘My car could have broken down anywhere along the freeway. It didn’t.44, it broke down in the45place:off the freeway, within walking distance of here. I’m still able to teach my class, and I’ve been able to arrange for the tow truck to meet me after class. If my car was46to break down today, it couldn’t have been arranged in a more convenient fashion.’”

“The secretary’s eyes opened wide, and then she smiled. I smiled back and headed for class.” So ended my story.

I47the sixty faces in my economics class at UNLV. Despite the early hour, no one seemed to be asleep.48, my story had touched them. Or maybe it wasn’t the story at all.49, it had all started with a student’s50that I was cheerful.

阅读下面短文，回答下面题。
在碳纳米管的研究问题上，当国外把主攻方向放在小直径时，我国科学家却另辟蹊径，瞄准了超长纳米管的合成。经过改进工艺等方法，他们成功地合成出3毫米长、形状酷似牙刷的定向碳纳米管列阵，长度居世界之最，使我国在“超级纤维”碳纳米管的研究尤其是合成方法上达到了世界领先水平。
作为石墨、金刚石等碳晶体家族的新成员，碳纳米管韧性很高，导电性极强，兼具金属性和半导体性，韧度比钢高100倍，比重只有钢的六分之一。因为它性能奇特，被科学家称为来来的“超级纤维”。它非常微小，5万个排列起来，才有人的一根头发丝宽，实际上是长度和直径之比很高的纤维。碳纳米管潜在的用途很诱人，可制成极好的微细探针或导线、性能颇佳的加强材料、理想的储氢材料。它使壁挂式电视进一步成为可能，将来有可能替代硅芯片，从而引发计算机行业的革命。
“长纳米管”的问世，克服了碳纳米管研究的主要障碍，使碳纳米管的生长成为可以控制的事情，有可能将整个碳纳米管的研究提高到新的层次。
(佚名《超长纳米管合成》)

对“碳纳米管”用途的理解，不正确的一项是：

A．用“碳纳米管”制成微细的探针或导线，其使用效果极好。

B．用“碳纳米管”制成的加强材料、储氢材料，其性能十分理想。

C．“碳纳米管”用于壁挂式电视机的研制，有可能使壁挂式电视机成为现实。

D．“碳纳米管”能够替代硅芯片，引发计算机行业的革命。
