Choosing the right resolution(决定决定)Millions of Americans began 2014 with the same resolution they started 2013 with,a goal of losing weight.However,setting weight lose as a goal is a mistake.返回目录返回目录专题二十五专题二十五科普知识型阅读理解科普知识型阅读理解真真题题典典例例To reach our goal of losing weightthe output,we need to control what we eatthe input(输入输入).That is,we tend to care about the output but not to control the input.This is a bad way to construct goals.The alternative is to focus your resolution on the input.Instead of resolving to lose weight,try an actionable resolution:“Ill stop having dessert for lunch,”or“Ill walk every day for 20 minutes.”Creating a goal that focuses on a wellspecified input will likely be more effective than concentrating on the outcome.返回目录返回目录专题二十五专题二十五科普知识型阅读理解科普知识型阅读理解真真题题典典例例Recently a new science behind incentives(激励激励),including in education,has been discussed.For example,researcher Roland Fryer wanted to see what works best in motivating children to do better in school.In some cases,he gave students incentives based on input,like reading certain books,while in others,the incentives were based on output,like results on exams.His main finding was that incentives increased achievement when based on input but had no effect when based on output.返回目录返回目录专题二十五专题二十五科普知识型阅读理解科普知识型阅读理解真真题题典典例例Fryers conclusion was that the incentives for inputs might be more effective because students do not know how to do better on an exam,aside from general rules like“study harder”.Reading certain books,on the other hand,is a wellset task over which they have much more control.返回目录返回目录专题二十五专题二十五科普知识型阅读理解科普知识型阅读理解真真题题典典例例As long as you have direct control over your goal,you have a much higher chance of success.And its easier to start again if you fail,because you know exactly what you need to do.返回目录返回目录专题二十五专题二十五科普知识型阅读理解科普知识型阅读理解真真题题典典例例If you want to cut down on your spending,a good goal would be making morning coffee at home instead of going to a cafe,for example.This is a wellspecified actionbased goal for which you can measure your success easily.Spending less money isnt a goal because its too general.Similarly,if you want to spend more time with your family,dont stop with this general wish.Think about an actionable habit that you could adopt and stick to,like a family movie night every Wednesday.In the long run,these new goals could become a habit.返回目录返回目录专题二十五专题二十五科普知识型阅读理解科普知识型阅读理解真真题题典典例例1The writer thinks that setting weight loss as a goal is a mistake because _.Ait is hard to

the air we breathe.返回目录返回目录专题二十五专题二十五科普知识型阅读理解科普知识型阅读理解新新题题预预测测Start with about 25,000 gallons of air.Now,press it all into a space smaller than your school lockerbecause thats the size of two superstrong,highpressure air tanks,made from fibre and fixed beneath the air car.Confining that much air inside those small tanks generates an internal pressure of over 4,000 pounds per square

not associated with earlier death,and premature greying is not,generally speaking,a sign of an illness or ill health in younger adults.There are,however,some specific health conditions associated with grey or white hair,but for most of us,going grey is just a fact of life.返回目录返回目录教师备用习题教师备用习题Hair colour comes from the pigment melanin(黑色素黑色素),which determines your individual shade.Hair without any melanin is pure white.The pigment is produced in cells called melanocytes,which inject pigment into the hair.At some point in everyones lifetime,these cells slow down and eventually stop producing colour.Scientists have yet to identify the exact mechanism by which melanocyte cells death occurs.返回目录返回目录教师备用习题教师备用习题A study of more than 4,000 women and men from 20 countries determined that about

grey hair by retirement age.Beginning at age 30,your chances of having grey hair go up 10%20%per decade.返回目录返回目录教师备用习题教师备用习题It may feel like you have more greys after a stressful event,but thats probably because middle age is basically a series of anxietyridden events.Between working,raising kids,and caring for older parents,the“sandwich”years of 4565 can be stressful,especially for women.They are also stressful when they naturally start to look older.At this point,there is still no silver_bullet to keep away the greys.返回目录返回目录教师备用习题教师备用习题1What would be the best title for this
