参考答案和解析
DDBBCC C语言对枚举的定义规定：在枚举中声明的各个枚举元素，如果没有明确指出某个枚举元素的值，它的上一个元素存在并有明确值的情况下，这个枚举元素的值为其上一个元素的值+1。在本题中，没有明确说明枚举元素em3的值，则em3=em2+1=1+1=2，进而可知，在printf()打印函数中，要打印的数组元素是aa[3]、aa[1]、aa[2]，因此最后的打印结果应当为“DDBBCC”。

阅读下列短文，从每篇短文后所给各题的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。AMy grandfather came from Hungary and was the only one in his family who settled down in the United States. The rest of his family remained in Europe. When World War I broke out, he seemed to have become another man, downhearted. Such obvious change was not born out of concern for his welfare, but out of fear: if his only son, my uncle, had to go to war, it would be cousin fighting against cousin.One day in 1918, my Uncle Milton received his draft notice. My grandparents were very upset. But my mother, at the age of 10, felt on top of the world about her soldier brother going off to war. Realizing how he was regarded by his little sister and all of her friends, my uncle bought them all service pins, which meant that they had a loved one in the service. All the little girls were delighted.The moment came when my uncle and the other soldiers, without any training but all in uniforms, boarded the train. The band played and the crowd cheered. Although no one noticed, I’m sure my grandmother had a tear in her eye for the only son. The train slowly pulled out, but not about a thousand yards when it suddenly paused. Everyone stared in wonder as the train slowly returned to the station. There was a dead silence before the doors opened and the men started to step out. Someone shouted, “The war is over!” For a moment, nobody moved, but then the people heard someone bark orders at the soldiers. The men lined up in two lines, walked down the steps, and with the band playing, marched down the street, as returning heroes, to be welcomed home. My mother said it was a great day, but she was just a little disappointed that it didn’t last a tiny bit longer.51. What the grandfather was most worried about was .A. the spread of the world warB. the safety of his two cousinsC. a drop in his living standardsD. his relatives killing each other

Because of her English, she was often treated unfairly. People in department stores, at banks, And at restaurants did not take her seriously ,did not give her good service ,pretended not to Understand her ,or even acted as if they did not hear her.My mother has realized the limitations of her English as well. When I was fifteen, she used to have me call people on phone to pretend I was she . I was forced to ask for information or even to yell at people who had been rude to her. One time I had to call her stockbroker (股票经纪人).I said in an adolescent voice that was not very convincing, “This is Mrs.Tan.”And my mother was standing beside me ,whispering loudly, “Why he don’t send me cheek already two week lone.”And then , in perfect English I said : “I’m getting rather concerned .You agreed to send the check two weeks ago, but it hasn’t arrived.”Then she talked more loudly. “What he want? I come to New York tell him front of his boss.” And so I turned to the stockbroker again, “I can’t tolerate any more excuse.

But now, I see it differently. To me, my mother’s English is perfectly clear, perfectly natural. It is my mother tongue. Her language, as I hear it, is vivid, direct, and full of observation and wisdom. It was the language that helped shape the way I saw things, expressed ideas, and made sense of the world.41.Why was the author’s mother poorly served?A.She was unable to speak good English.B.She was often misunderstood.C.She was not clearly heard.D.She was not very polite.
AIt was the first snow of winter – an exciting day for every child but not for most teachers. Up until now, I had been old enough to dress myself, but today I would need some help. Miss Finlayson, my kindergarten teacher, had been through first snow days many times, but I think she may still remember this one.I managed to get into my wool snow trousers. But I struggled with my jacket because it didn’t fit well. It was a hand-me-down from my brother, and it made me wonder why I had to wear his ugly clothes. At least my hat and scarf were mine, and they were quite pretty. Finally it was time to have Miss Finlayson help me with my boots（靴子）.In her calm, motherly voice she said, “By the end of winter, you will all be able to put on your own boots.” I didn’t realize at the time that this was more a statement of hope than of confidence（信心）.I handed her my boots and stuck out my foot. Like most children, I expected grown-ups to do all the work. After much pushing, she managed to get the first one into place and then, with a sigh, worked the second one on too.I announced, “They’re on the wrong feet.”She struggled to get the boots off and went through the joyless task of putting them on again.“They’re my brother’s boots, you know,” I said. “I hate them!”Somehow, from long years of practice, she managed to act as though I wasn’t an annoying（烦人的）little girl, She pushed and pushed, less gently this time. With a greater sigh, seeing the end of her struggle with me, she asked, “Now, where are your mittens（连指手套）?”I looked into her eyes and said, “I didn’t want to lose them, so I hid them in the toes of my boots.”41．The little girl was more satisfied with her__________-.A．trousersB．jacket C．boots D．hat

根据下面资料，回答Bum rate is the speed at which a start up business consumes money. My rate would be $50,000 a month when my new media company started. So, I began looking around for individuals who would be my first investors. "Angel money" it was called. But when I reviewed my list of acquaintances to find those who might be able to help, I found the number got small. With no other choices, I began meeting with the venture-capital companies. But I was warned they took a huge share of your company for the money they put in. And if you struggled, they could drop you cold. As I was searching for "angel money", I started to build a team who trusted me even though I didn′t have money for paying checks yet. Bill Becker was an expert in computer programming and image processing at a very famous Media Lab at M.I.T. With his arrival, my company suddenly had a major technology "guy" in-house. Katherine Henderson, a film maker and a former real-estate dealer, joined us as our director of market research. Steve White came on as operating office. He had worked for the developer of a home-finance software, Quicken. We grabbed him. We had some really good people, but we still didn′t have enough money. One night, my neighbor, Louise Johnson, came for a visit. She and I were only nodding acquaintances, but her boys and ours were constant companions. She ran a very good business at the time. Louise was brilliant and missed nothing. She had been watching my progress closely. She knew I was dying for money and I had prospects but could offer no guarantees of success. She told me that her attorney had talked to mine and the terms had been agreed upon. She handed me an envelope. Inside was a check for $500,000. I almost fell down. I heard her voice as if from heaven. "I have confidence in your plan," she said. "You′ll do well. You′re going to work for it, but it′ s satisfying when you build your own company." Who could have thought I′ d find an angel so close to home? There were no words sufficient for the moment. We just said good night. She left and I just stood there, completely humbled and completely committed. Louise decided to lend money to the author because _____________.A.she wanted to join his companyB.she knew he would build a teamC.she knew his plan would succeedD.she wanted to help promote his sales
