阅读理解。 What would you think if I told you I could eat 40 percent more food than other peopleeating boxes of ice cream,bowls of noodles and plates of meatall while losing weight? You might hate me,thinking I have one of tho annoyingly good metabolisms (新陈代谢) that just burn up fat the instant it enters my body.You might wonder if I have an intestinal (肠的) worm,or perhaps an eating disorder.Or maybe you'd just shrug your shoulders and figure I have a rich fantasy life.You'd be wrong. For my body to finish such a surprising task,I would have to be a mou.Not just any mou,but one lucky enough to be involved in a new study at Baylor College of Medicine in Houston. After identifying an enzyme (酶) that allows fat to be stored in the body,scientists fed mice without tho enzymes,and found tho mice were able to consume far more food than other miceand still weigh 10 to 15percent less.   Best of all,the mice that had no enzymes were in very good health,producing baby mice with no problem and generally acting like any other mou.That's great news for obesity rearchers,who think that scientists may figure out a way to prevent the fatmetabolizing (脂肪代谢) enzyme in humans and control weight gain.And such a pill would be very exciting for many struggling to get rid of dangerous extra pounds. But don't start planning any big dinner just yet:At this point,of cour,any pill for humans is but a twinkle (闪烁) in the eye of every medicine company's CEO.More tests are to be made,and eventuallyhumans will be introduced in the test. But for now,unfortunately,control in diet is still key.1.What does "such a surprising task" in Paragraph 3 refer to?A.Eating a lot of food while losing weight.   B.Burning fat very quickly.C.Controlling the diet.   D.Having a rich fantasy life.2.Why did the author say he/she had to be a mou in Paragraph 4?A.Becau a mou can lo weight no matter how much it eats.B.Becau the weightlosing tests were made on the mou.C.Becau the mou has a very good metabolism.D.Becau the author wants to try the food without the enzyme.3.What does the author want to show through the last two paragraphs?A.You can be free of guilt when having big dinners.B.Scientists cannot find the key to identifying the enzyme.C .Don't overeat before the test is made on humans.D.It is unnecessary to control weight at prent. 题型：未知难度：其他题型
