阅读理解 A new study suggests that the way to weight loss may be clear.A couple of glasses of water before meals help dieters lose about 5 pounds more than those who do not drink water.While drinking water before a meal may fill a person up，the contents of their meal are important as well.Should a person be eating a low－fat diet or a lowcarbohydrate (低糖的) diet? Or does it matter at all?Recent research suggests that one diet isn’t any better than the other.A few weeks before the water study，another concluded that lowfat and lowcarbohydrate diets tied in weight loss.While the lowcarbohydrate dieters did show a slight increase in good cholesterol (胆固醇) and a reduction in blood pressure，there was not much difference in the dieters’weight loss.The point here is that the person had to stick to the diet.What helps a person see a diet through? It could be body type.A study published in the Journal of the American Medical Association，as reported by Timemagazine，found that body shape is the key to which diet a person will be able to stick with.Apples are people who carry most of their weight above the belt，while pears carry their weight around their hips (臀部)．Apple types were more likely to be highinsulin secretors (高胰岛素分泌者) who respond more strongly to carbohydrates in their bodies.They lost the most weight on a lowcarbohydrate diet.Pears were lowinsulin secretors who lost the same amount of weight on both diets.Unstable (不稳定的) insulin levels can create stronger hunger senses，causing the apple types to go off their diet plans.All of these studies again come down to choosing the diet that helps you eat less.The bodytype diet does make some sense as men are more likely to be apple types，with larger stomachs，and tend to do well on higherprotein diets，while women，who tend to carry weight around their hips，find themselves drawn to the lowfat diets.The reality is if a diet is failing you try another one.A plan you can’t，or won’t，stick to will never work，no matter what the research says1.If you want to lose weight but don’t know what diet suits you，you can always ________A.drink a few cups of water after each mealB.drink a few cups of water before each mealC.eat plenty of pearsD.eat plenty of apples2.Compared with a lowcarbohydrate dieter，a lowfat dieter may ________A.lose weight fasterB.put on weight fasterC.have less good cholesterolD.have a lower blood pressure3.Which of the following statements is TRUE according to the passage?A.Women on highprotein diets usually do well in weight lossB.Men on highcarbohydrate diets usually do well in weight lossC.Men usually like eating apples while women mostly enjoy pearsD.Whether a person can stick with a diet depends largely on his or her body shape4.In the author’s opinion，________A.men don’t get hungry as easily as womenB.apple types work better than pear types in weight lossC.the result of the recent research is not of much valueD.strong will as well as proper methods is the key to weight loss

BCDD解析1.B根据第一段第二、三句可知，饭前喝几杯水会使人有饱胀感，从而有助于减肥。2.C根据第二段第三句可知，低脂肪饮食和低糖饮食在减肥方面差别不大，只是低糖饮食者的好胆固醇会有所升高，血压会有所降低，故相较于低糖饮食者，低脂肪饮食者的好胆固醇会相对低一些。3.D本文第二段最后一句和第三段第一句都明确提到一个人是否能坚持某种饮食和体形有很大关系。4.D作者通过本文第二段倒数第三句和本文最后一句都表明：要想减肥，除了适当的方法，坚持不懈也是非常重要的。

这个问题我还想问问老师呢
