researchers.“It was a small surprise，for it is against the mon belief，”said Pieter van Baal，who led the study.“But it makes sense.If you live longer，then your costs of the health system will be more.”The researchers found that from age 20 to 56，obese people racked up(累计)the most expensive health costs.But on average，healthy people lived 84 years.Smokers lived about 77 years，and obese people lived about 80 years.Smokers and obese people tended to have more heart disease than healthy people.Therefore in the long run，the thin and healthy group spent about $417，000，from age 20 on.Smokers spent about $ 326，000 and obese people $371，000.“The result throws a bucket of cold water onto the idea，based on guesswork，that obesity is going to cost trillions of dollars，”said Patrick Basham，a professor of health politics.“If were going to worry about the future of obesity，we should stop worrying about its financial impact，”he said.“The benefits of obesity prevention may not be seen immediately in terms of cost saving in tomorrows budget，but there are long-term gains，”said Baal.“These are often immeasurable when it es to people living longer and healthier lives.”In the meanwhile，he said that governments should recognize that successful smoking and obesity prevention programmes mean that people will have a higher chance of dying of something more expensive later in life.“Lung cancer is a cheap disease to treat because people dont survive very long.But if they are old enough to get Alzheimers(早老性痴呆病)one day，they may survive longer and cost more.We are not advising that governments stop trying to prevent obesity，”Baal said.“But they should do it for the right reasons.”【语篇解读】本文介绍了减肥和戒烟能使我们活得更长久，但是却不能省钱，也许会花得更多。1Among middle-aged people，whose costs of the

programs解析：考查推理判断。根据最后两段的内容可推知，政府预防人们肥胖的目的应该是让人们更长寿、更健康。答案：C4What would be the best title for this text?AA recent medical study shows the truth about healthBPreventing obesity and smoking may cost moreCObesity and smoking lead to expensive diseasesDGovernments change attitudes towards obesity and smoking解析：考查标题判断。根据第一段的第一句“Preventing obesity(肥胖)and smoking can save lives，but it doesnt save

to artists，writers，or dancers，rather than ourselves._1_ The following tips are a great beginning for developing our creativity.1Get out of your fort zoneWe eagerly accept the familiar and fear the unknown.Break out of your usual patterns and wele creativity into your life.As stated earlier，the human brain was designed to recognize patterns._2_ In fact，our fort zone is nothing more than a collection of patterns.As we bee more efficient at recognizing and using patterns，we rely less on creativity to find new paths.We should force ourselves out of our fort zones and open up new possibilities.2Try different thingsIf you always do what youve always done，youll always get what youve always got.We are creatures of habits and routines，and creativity hates routines.If you usually drive to work，take the subway for a few days._3_ Interrupt your routine，experiment and try something new.New things are often creative，but the same old thing never is.3_4_Having a great idea is not enough；you must work to make it a reality.Have you ever seen a new product and realized that you thought of the same thing long ago？Yet someone else is making money with“your”idea._5_ The difference between a dreamer and a doer is action.Do whatever it takes to bring your ideas to life.If you can put them into practise，you are well on your way to improving your cr
