  【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。

  1.C 考查推理判断。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。

  2.A 考查推理判断。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。

  3.A 考查主旨要义。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。

  4.B 考查推理判断。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。

  二、单句语法填空

  答案:permission official permission "官方许可",在句中是名词短语作主语。
