2. 根据题目,我们可以知道等差数列的公差d = 7 - 3 = 4,因此通项公式为an = a1 + (n-1)d,将a1 = 3代入,得到an = 3 + (n-1)* 4 = 4n - 1。
3. 对数函数的定义域是其内部参数大于0的范围,因此y = ln(x)的定义域为x > 0。
4. 圆的方程中,圆心坐标可以通过公式(a, b) = (2, 3)得到,其中a 和b分别是圆的方程中的常数项。
5. 根据三角函数的基本恒等式sin^2θ + cos^2θ = 1,我们可以解得cosθ = √(1 - sin^2θ) = √(1 - (3/5)^2)。
三、解答题(每题10分,共30分)1. 求函数f(x) = x^3 - 3x^2 + 2的极值点。

Millions of people die of hunger in southern Africa every year, but when Zambia was offered thousands of tons of free maize by the US, the government politely said no.“We don ’t know whether the food is safe,” said Zambia ’s commerce, Trade and Industry Minister Dipak Patel.His worries are shared by countries around the world that are in two minds about America ’s genetically modified (GM,转基因的)crops .Just last week, EU (欧盟)member nations were discussing whether or not to import GM sweet corn from the US .Ever since people started farming, they have tried to crossbreed (杂交)plants to make them stronger or better tasting. At one time, only related plants could be crossed with each other .But when GM techniques were developed in the 1970s, scientists were able to put a single gene from a living creature into an unrelated creature.This means they can make crops more productive and resistant to disease by adding genes from other species .They can also create food with special characteristics, such as “golden rice ”, which is enriched with vitamin A. But many people believe GM foods are a health risk.At the moment, the official argument is that GM foods “are not likely to present risks for human health ”. But there are still many questions to be answered as the foods are produced in different ways.Some experts believe the genetic material added to plants can transfer to humans and give damage to our bodies. Further harm could be caused by the genes from GM plants crossbreeding with naturally produced crops .People in China are also getting worried about GM foods. More than 70 percent of thecountry ’s soybean oil is produced from imported GM soybeans. Meanwhile, an investigation last November found that 12 of 60 famous foods sold across the country were GM products. The government has begun to introduce a marking system for GM goods so that people can choose whether or not to eat them.【小题1】Which is the best title for the passageA .Harmful GM foodsB .Advantages of GM foodsC .GM foods, a health riskD .the Techniques of GM foods【小题2】Why has Zambia refused the American free maizeA .they decide to follow EU member ’s advice○…………外…………○…………装…………○…………订…………○…………线…………○………… 学校:___________姓名:___________班级:___________考号:___________○…………内…………○…………装…………○…………订…………○…………线…………○………… C .they care little about the problem of starvation D .they are too proud to accept free offer 【小题3】It has been proved that _________.

Whether you ’re eating at a fancy restaurant or dining in someone ’s home. Proper table manners are likely to help you make a good impression. According to a US expert, Emily Post, “All rules of table manners are made to avoid ugliness.” While Henry Hitchings of the Los Angeles Times admits that good manners can reduce social conflict, he points out that mostly their purpose is protective - they turn our natural warrior-like selves into more elegant ones. So where did table manners come from In medieval England, a writer named Petrus Alfonsi took the lead to urge people not to speak with their mouths full. And King David I of Scotland also proposed that any of his people who learned to eat more neatly be given a tax deduction (减除). Disappointingly, that idea never caught on . It was during the Renaissance, when there were real technical developments, opinions of correct behavior changed for good. “None of these was more significant than the introduction of the table fork,” wrote Hitchings. “Gradually, as forks became popular, they brought the new way of eating, making it possible, for instance, to consume berries without making one ’s fingers dirty.” Forks were introduced to Britain in 1608 and 25 years later, the first table fork reached America. Yet while most of the essentials (基本要素) are the same on both sides of the Atlantic, there are a few clear differences between what ’s normal in the US and what holds true in the UK. For example, in the US, when food needs cutting with a knife, people generally cut a bite, then lay aside the knife and switch the fork to their right hand. Then they pick up one bite at a time. By contrast, Britons keep the fork in the left hand and don ’t lay the knife down. Though globalization has developed a new, simpler international standard of table manners, some people still stick with the American cut-and-switch method.The Los Angeles Times noted, “They are hanging on to a form of behavior that favors manners above efficiency.” 【小题1】What does the story mainly talk about A .The importance of proper table manners .○…………外…………○…………装…………○…………订…………○…………线…………○………… ※※请※※不※※要※※在※※装※※订※※线※※内※※答※※题※※ ○…………内…………○…………装…………○…………订…………○…………线…………○………… C .Some unwritten rules of table manners in the US and UK.

The way people hold to the belief that a fun-filled, and pain-free life equals happiness actually reduces their chances of ever attaining real happiness. If fun and pleasure are equal to happiness then pain must be equal to unhappiness. But in fact, the opposite is true: more often than not things that lead to happiness involve some pain.As a result, many people avoid the very attempts that are the source of true happiness. They fear the pain inevitably(不可避免的) brought by such things as marriage, raising children, professional achievement, religious commitment (义务), self - improvement.Ask a bachelor(单身汉) why he resists marriage even though he finds dating to be less and less satisfying. If he is honest he will tell you that he is afraid of making a commitment. For commitment is in fact quite painful. The single life is filled with fun, adventure, excitement. Marriage has such moments, but they are not its most distinguishing features.Couples with infant children are lucky to get a whole night ’s sleep or a three - day vacation. I don ’t know any parent who would choose the word fun to describe raising children. But couples who decide not to have children never know the joys of watching a child grow up or of playing with a grandchild.Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations. It liberates time: now we can devote more hours to activities that can genuinely increase our happiness. It liberates (解放)money: buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless. And it liberates us from envy: we now understand that all those who are always having so much fun actually may not be happy at all.【小题1】According to the author, a bachelor resists marriage chiefly because _______ .○…………外…………○…………装…………○…………订…………○…………线…………○………… 学校:___________姓名:___________班级:___________考号:___________○…………内…………○…………装…………○…………订…………○…………线…………○………… B .he believes that life will be more cheerful if he remains single C .he finds more fun in dating than in marriage D .he fears it will put an end to all his fun adventure and excitement 【小题2】From the last paragraph, we learn that envy sometimes stems from ________ . A .hatred B .misunderstanding C .prejudice D .ignorance 【小题3】What is the author trying to tell us A .Happiness often goes hand in hand with pain. B .One must know how to attain happiness. C .It is important to make commitments. D .It is pain that leads to happiness.答案解析部分(共有 4 道题的解析及答案)二、阅读理解1、2、3、4、In North America, most students go to school on the school bus.
