the glycemic index(血糖指数), or gi rating tells us. foods with gi scores above 75 are considered highgi foods, leading to faster sugar development. bananas have a gi of 62, which is considered low.weight loss can be a struggle for anyone, but it is especially hard for diabetics(糖尿病患者). a study looked at how the starch from unripe bananas affected the weight of a group of obese diabetics. after four weeks of a diet high in bananas, diabetics lost significantly more weight than on a control diet. they also saw improvements in insulin sensitivity from the banana diet.whats more, bananas have been shown to cut risks of strokes, diabetes and cancers.(bananas are the most powerful fruit for lowering the risk of kidney cancer.) bananas are also a rich source of fiber, which has been shown to help weight loss. bananas that still have some green on the skin are even higher in fiber.skins from green bananas can be taken and, after removing the stem and dark tip, cut into small pieces 23 inches long and 1/2 inch wide. these pieces can be made into a tea or added to a dish. when you eat the skins, be sure you are eating organic bananas. the flesh of regular bananas is low in pesticides, but the skins are not.【解题导语】本文反驳了“吃香蕉会使人发胖”这一错误观点，告诉大家香蕉不会使身体分泌很多胰岛素而导致脂肪增加，相反，香蕉对身体健康有着诸多好处。1what conclusion can we draw from paragraphs 1 & 2?abananas are likely to make people fat.binsulin determines the amount of sugar.clowgi foods can turn into sugar more slowly.dthe faster the food becomes sugar, the less insulin.c解析：推理判断题。根据第二段中“how can you know if food makes a lot of sugar quickly? the glycemic index(血糖指数).faster sugar development.”可知，血糖指数高的食物往往能更快地转化成糖分，反之，血糖指数低的食物转化成糖分的速度较慢。故选c。2what does the author say about bananas?aincluding bananas in diets is good for health.bbananas can cure people suffering kidney cancer.ceating organic bananas can protect people from strokes.dbananas abundant fiber improves insulin sensitivity.a解析：推理判断题。根据文章第三段中的“.diabetics lost significantly more weight than on a control diet. they also saw improvements in insulin sensitivity from the banana diet.”及第四段的“bananas have been shown to cut risks of strokes, diabetes and cancers.weight loss.”可知，香蕉可以帮助人们减肥，也能降低人们患中风、糖尿病及癌症的风险，由此可得出这样的结论：将香蕉列入日常饮食对人们的健康有益，故选a。3what is discussed in the last paragraph?athe use of banana skins.bthe benefits of banana skins.cthe importance of banana skins.dthe ways of choosing organic bananas.a解析：段落大意题。根据最后一段的内容尤其是“can be made into a tea or added to a dish”可知，本段主要讲的是香蕉皮的用途。故选a。4in which section of a newspaper can we read this passage?aeducation.bhealth.cculture.dscience.b解析：推理判断题。纵观全文可知，香蕉不仅有助于减肥，还能降低人们患中风、糖尿病及癌症的风险，而且香蕉皮也有用处。由此可知，本文最有可能出现在报纸的健康专栏。故选b。三、书面表达。微博(micro blog) 已成为时下学生常用的交流方式。人们
