It is a commonplace among moralists that you cannot get happiness by pursuing it. This is only true if you pursue it (62) . Gamblers at Monte Carlo are pursuing money, and most of them lose it instead, (63) there are other ways of pursuing money, which often succeed. (64) it is with happiness. If you pursue it by (65) of drink, you are forgetting the hang-over (宿醉). Greek philosopher Epicurus pursued it by living only in congenial (趣味相投的) society and eating only dry bread, supplemented by a little cheese on feast days. His method (66) successful in his case, but he was a sick and weak man, and most people would need something more (67) . For most people, the pursuit of happiness, (68) supplemented in various ways, is too abstract and theoretical to be adequate as a personal rule of life. But I think that whatever personal rule of life you may choose it should, except in rare and heroic cases, be compatible (69) happiness. There are a great many people who have all the (70) conditions of happiness, i.e. health and a sufficient income, and who, (71) , are profoundly unhappy. In such cases it would seem as if the (72) must lie with a wrong theory as to how to live. In one (73) , we may say that any theory as to how to live is wrong. We imagine ourselves more different from the animals than we are. Animals live on (74) , and are happy as long as external conditions are (75) . If you have a cat it will enjoy life if it has food and warmth and opportunities for an (76) night on the tiles. Your needs are more complex than those of your cat, but they still have their basis in instinct. In civilized societies, (77) in English-speaking societies, this is too (78) to be forgotten.

Technology brought great convenience to our lives yet it also created multiple social problems. What do you think about technology Please write about your opinion. Give two or three examples to illustrate your point. You should write 160 - 200 words neatly on ANSWER SHEET 2.

In his recently written autobiography, he ____________(把自己的成功归功于父母的鼓励).

Technology was supposed to set us free, but in the car industry it’s locking us out of our vehicles. And as many more car keys contain electronic chips and come equipped with computerized anti-theft ignition systems, this problem looks set to worsen, experts say. The days of visiting a hardware store for an extra car key are quickly vanishing, and consumers and advocacy groups say the time needed to replace missing or lost electronic keys is inordinately long and expensive - and drivers may have no recourse (求助对象) when dealerships are not open. Getting a new electronic key can cost hundreds of dollars, including the cost of towing a car. Unlike an old-fashioned mechanical key, which unlocks a door or starts an ignition with its "teeth", an electronic car key works by sending a code that must be read electronically before a vehicle’s engine will start. The technology for these keys is evolving rapidly and only a few locksmiths are investing in the technology needed to replace them, meaning most drivers who lose their keys are forced to visit a dealership for a replacement. In a study of the cost of replacing keys in 50 makes and models of vehicles in the Washington, D. C. area, Ditlow’s group found that the average cost of an old-fashioned mechanical key was $12, while the average local dealer price of a "smart" or electronic key was $152. The highest key replacement cost was $335 for a 2004 Lexus IS300. Ditlow speculates that with a healthy profit coming from their service and parts replacement divisions, auto companies are reluctant to make the codes for their electronic keys more readily available. For their part, automakers say making the information readily accessible would lessen the effectiveness of their anti-theft systems. To remedy this, Ditlow has suggested that the National Insurance Crime Bureau, which combats theft and insurance fraud, maintain a database of key codes so they can be easily located. Some automakers do indeed provide their information, but not all. And as automobile electronics become increasingly sophisticated and increasingly common, the electronic key problem looks set to continue to dog drivers, experts say. Most luxury cars now have sophisticated electronic key systems, and car lockouts are among the most common reasons for roadside-assistance calls according to the AAA. Replacing an electronic car key costs ______ on the average according the Ditlow survey.
