（或的叠加性）最大项表达式：将使F=0的最大项“与”起来。
（与的公共性）两者之间为互补关系。
三、分析、计算题（每题10分，共20分）1．图1示电路的接法是否正确？若正确，请写出F的表达式。
（注：图1中的逻辑门为集电极开路“与非”门，即OC门）答：“与非”门输出端不能直接并联。
F=F1×F2 =AB·CD =CD ABF CBVcc图 12．某D/A转换器的最大输出电压为5V，分辨率不大于1mV。
1)试确定该D/A的最少位数；2)该D/A的实际分辨率为多少?答：1）当满量程为5V，分辨率为1mV时，就是说每变化一位的数据增加1mV，那么1mV/5V=0.0002，代表一位，就是两万倍，则DAC位数为n，2^n要与10000最接近且满足1mV的要求，通过计算，2^13=8192与2^14=16384相比，应该得选用13位的DAC最接近，所以该D/A的最少位数是13.2）该D/A的实际分辨率为0.61mV。

He always acted as if he thought I wasn’t one of the families. There was an advantage in being one of the families, for he didn’t bite the family as often as hebit strangers.In his last years Muggs used to spend almost all his time outdoors. As a result the garbage man, the iceman and the laundryman wouldn’t come near the house. We had to drag the garbage down to the corner, take the laundry out and bring it back and meet the iceman away from home. After this had gone on for some time we hit on a good idea for getting the dog into the house so that we could lock him up while others needed to come inside the house. Muggs was afraid of only one thing, thunder and lightning. It frightened him out of his senses. He would rush into the house and hide under a bed or in clothes closet. So we made a thunder machine out of a long narrow piece of iron with a wooden handle on one end. Mother would shake this with all her strength when she wanted Muggs into the house. I suppose it was the most complex system for running a household that was ever devised. It took a lot out of Mother.1．If you were a member of family, you had the “advantage” of ________.A. being able to touch Muggs without being bittenB. being protected by Muggs from strangersC. being bitten less often than strangers were by muggsD. being bitten less severely than strangers were by Muggs2．The garbage man wouldn’t come near the house because_________.A. he did not like families with dogsB. he knew the family were unfriendly to himC. he could pick up the garbage at the cornerD. her was afraid of being bitten by Muggs3．Judging from the context, “we hit on a good idea” most probably means______A. we felt excited about a good ideaB. we suddenly thought of a good ideaC. we agreed on a good ideaD. we carefully studied a good idea4．The thunder machine was made to ______.A. frighten Muggs into the houseB. draw Mugg’s attention when someone came mear the houseC. give the children something to play withD. get Muggs used to thunder and lightning5．We learn from the passage that Muggs _____.A . was the worst dog the author ever sawB. caused a lot of trouble to the familyC. was a dog nobody ever likedD. changed the way of housewives to run a householdPassage 2Questions 6 to 10 are based on the following passage:The Ayalas were an ordinary American family just like millions of others: mom, dad, a boy and a girl. Until, that is, daughter Anissa was found to be suffering from leukemia.Her parents soon learned the dreadful truth: their daughter was under sentence of death. Leukemia patients usually die within five years without successful bone marrow transplantation. At this point Anissa’s best bet was her brother Airon, but his bone marrow proved unfit. Next, the Ayalas searched nationwide for a donor. Time was running out.Anissa’s final hope was a child who did not, as yet, exist. Earlier the father Abe had had an operation so there would be no more children. He had to have another operation. At the age of 43 Anissa’s mother gave birth to another baby, knowing that the chances against the bone marrow of the new arrival being fit for Anissa were three to one. They were lucky. A daughter who could save her sister’s life was born.After a fourteen-month wait, doctors at Los Angeles’ City of Hope Hospital took a cupful of healthy bone marrow from the new baby. It was then transplanted into the body of her elder sister. Even then, doctors were not fully sure. Anissa had a 70% chance of success. Fortunately, it succeeded and Anissa’s health improved gradually. A year later, in June 1992, she got married and looked forward to along life together with her husband.6．What was the mane of the newborn baby?A. AnissaB. AironC. AbeD. Not mentioned in the passage7. Whey did the father have another operation?A. To get back his ability to give birth to more babies.B. To see if his bone marrow is fit for his sick daughter.C. He was sick himself.D. He wanted to give his bone marrow to his daughter.8. How many people’s bone marrow matched that of the sick daughter before her sister was born?A. OneB. NoneC. At least threeD. Two9. How old was the sick daughter when she was cured?A. ThirteenB. Forty-threeC. FiveD. In her adulthood10. Which of the following words best describe the fate of the sick daughter?A. UnfortunateB. LuckyC. UnalterableD. ComplicatedPassage 3Questions 11 to 15 are based on the following passage:Extensive new studies suggest that the world has made extraordinary progress in reducing poverty in recent decades. The research suggests that the pace of economic progress has been rapid and continued for decades, built on the foundations of relative political stability, rising trade, and economic liberalization after two world wars. One new study, published recently by the Institute for International Economics in Washington, find that the proportion of the 6.1 billion people in the world who live on $1 a day or less shrank from 63 percent in 1950 to 35 percent in 1980 and 12 percent in 1999. By some other measures, the progress has been more modest. Still, economists agree that poverty has plunged in key nations such as India and especially China, thanks to slowing population growth as well as economic freedom. "This is a huge success for the world as a whole," says Harvard University economist Richard Cooper. "We are doing something right."The news comes as the World Bank is about to open its annual meeting in Washington- an event that has been troubled in recent years by protests that the Bank and its sister Institution, the International Monetary Fund，have done too little for the world's poor. The new economic research will not put an end to that dispute. Vast populations remain poor, and many still question the wisdom of World Bank policies. Nonetheless, the research findings are helpful to understand what policies should be followed by those institutions and hundreds of other development groups working very hard to hasten the pace of world economic progress. If dramatic gains are under way, the present policies-calling for open markets, free business activities and tight monetary control-are working and correct.But critics of IMF and World Bank policies maintain that such economic success stories as Japan, China, South Korea and Singapore are rooted in more than just "free" markets. These nations have managed to grow rapidly, and thereby reduce poverty, by limiting imports when their domestic industries were young, pushing exports to rich nations, and putting controls on purely international financial flows. The have been open to foreign-owned factories but have often insisted that those investors share the knowledge and skill on modern technologies.11. The word "plunged" in the first paragraph means ________.A. decreasedB. climbedC. increasedD. dropped into water12. From the passage, we learn that ______.A. World Bank has done nothing to help the poor in the worldB. IMF only helps the rich in the worldC. World Bank controls all the banks in the worldD. There are some demonstrations against World Bank in recent years13. According to this passage, in _____, the world had the largest number of poor people.A. 1999B. 1980C. 1950D. 199014. According to the author, the economy of East Asian countries grew very fast because of the following measures EXCEPT ______.A. encouraging exportB. opening up to foreign investmentsC. limiting international financial flowsD. controlling import15. The best title for this passage might be ______.A. China's Contribution to the Reduction of Poverty in the WorldB. World Bank's Extraordinary Progress in Recent DecadesC. India's Leading Role in Reducing Global PovertyD. Global Progress in Reducing PovertyPart II Vocabulary and Structure (20%)1.
