阅读下面短文，请根据短文后的要求答题。(请注意问题后的字数要求)

　　[1]Losing weight is hard enough．Keeping it off is even harder．Now a new study by researchers at Penn State suggests that the techniques that work for losing weight aren't necessarily the same as those that help keep you slim．

　　[2]First the researchers surveyed over 1, 100 people who had achieved significant weight loss and maintained(维持)it．The researchers identified 36 weight－loss and weight－maintenance practices that at least10％ of the group used．

　　[3]Then the researchers conducted a national telephone survey of overweight people who had tried to lose weight and keep it off with varying success： about 11％reported successfully losing weight, and 21％ were able to maintain that loss for at least a year．

　　[4]The survey found people who ________ did so by participating in weight loss programs, cutting back on sugar, eating healthy snacks, not skipping meals and participating in different types of exercise．

　　[5]Still．Say many nutrition and obesity experts．The basic principles of weight loss and maintenance are the same; you have to eat a healthy diet and increase your exercise．people who lose weight and keep it off tend to eat significantly healthier foods and do a lot more exercise than the average American．

　　[6]But what may maintain between weight－loss and maintenance is a person's attitude; rather than focusing on actively losing weight in the short term．People have to start focusing on long－term, permanent lifestyle changes and behaviors, if they want to maintain the weight that's been lost．The key to success, experts agree, is motivation, not necessarily the particulars of your weight－loss program．

Answer 1

答案：
解析：

1．By providing a new study． 　　2．lost weight successfully．本句意为：研究结果显示，那些减肥成功是采用与减重有关的方法来达到成果的。 　　3．Permanent motivation．从最后一段最后一句“在专家们看来，成功的关键是保持动力，这不仅仅是在你的减肥计划中的某一部分，应该是贯穿始终的。” 可知。 　　4．You should eat a healthy diet and increase your exercise．根据第五段“你必须养成健康饮食的习惯，同时增加体育运动。能够在减肥之后有效的保持成果的人们通常在饮食方面非常的健康，并且要比普通人更加多的参与运动。” 可知。 　　5．How to keep the weight off．第一段的第二句Keeping it off is even harder．(那么保持住减肥的成果不反弹则是难上加难。)是主旨所在。
