【正文】 r and hotter.D. Not all animals are as smart as desert elephants.CAt the beginning of my 8:00 . class one Monday at UNLV（拉斯維加斯內(nèi)華達大學(xué)）, I cheerfully asked my students how their weekend had been. One young man said that his weekend had not been very good. The young man then proceeded to ask me why I always seemed to be so cheerful. His question reminded me of something I’d read somewhere before: “Every morning when you get up, you have a choice about how you want to approach life that day,” I said to the young man. “I choose to be cheerful.” “Let me give you an example,” I continued. “In addition to teaching here at UNLV, I also teach out at the munity college in Henderson. One day a few weeks ago I drove to Henderson. I exited the freeway and turned onto College Drive. But just then my car died. I tried to start it again, but the engine wouldn’t turn over. So I put my flashers on, grabbed my books, and marched down the road to the college.” “As soon as I got there, the secretary in the Provost’s office asked me what had happened. ‘This is my lucky day’, I replied, smiling.” “Your car breaks down and today is your lucky day?” She was puzzled, “What do you mean?”“I live seventeen miles from here. I replied. My car could have broken down anywhere along the freeway. It didn’t. Instead, it broke down in the perfect place: 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 was meant to break down today, it couldn’t have been arranged in a more convenient fashion.” you want to be cheerful you should ___________.A. try to succeed in doing everythingB. try to please your boss every dayC. earn a lot of money by workingD. choose to be cheerful every day underlined phrase “turn over” in the third paragraph means “________”A. roll over B. work normally C. stopped suddenly D. move around to this passage we can infer that the teacher’s car broke down ____.A. near UNLV B. along the highwayC. near Henderson D. at the munity college one of the following is TRUE?A.

These laptops connect people to their workplace. In the United States today, laptops also connect students to their classrooms.Westlake College in Virginia will start a laptop puter program that allows students to do schoolwork anywhere they want. Within five years, each of the 1500 students at the college will receive a laptop. The laptops are part of a $10 million puter program at Westlake, a 110yearold college. The students with laptops will also have access to the Internet. In addition, they will be able to use to “speak” with their teachers, their classmates, and their families. However, the most important part of the laptop program is that students will be able to use puters without going to puter labs. They can work with it at home, in a fastfood restaurant or under the trees，anywhere at all
