[解析]
(1)C.推理判断题。根据上文"You may not have heard the words "freshman fifteen" before,but they are very important for students who are entering university.(你可能没听过"新生十五"这个词,但它们对即将进入大学的学生来说非常重要)"以及后文""Fifteen" refers to fifteen pounds—the fifteen pounds added to a student's weight in his or her first year.("十五"指的是十五磅——学生第一年增加的十五磅体重)"可知,上文提到了"新生十五"这个词,后文则解释了"十五"的含义,可知本句承接上文就"新生"这一词进行解释,C选项中freshman对应上文中freshman。故C选项"新生是大学一年级的学生"符合语境,故选C.
(2)D.推理判断题。根据后文"Some students choose unhealthy food,because now their parents are not nearby to help them choose.Some students visit the kitchen many times while studying.Late at night,some students get unhealthy fast food such as French fries and chicken nuggets with soda to drink.(一些学生选择不健康的食物,因为现在他们的父母不在身边帮助他们选择。有些学生在学习的时候经常去厨房。深夜,一些学生吃不健康的快餐,如炸薯条和鸡块苏打饮料)"可知,本段主要是关于大学厨房提供不同种类的食物,而学生的选择各有不同,D选项中kitchens对应后文中the kitchen。故D选项"大学厨房提供许多种类的食物"符合语境,故选D.
(3)F.推理判断题。根据后文"Here are some ideas(下面是一些建议)"结合后文主要就避免大学长胖提出了一些建议,故F选项"如果你很小心,你不必增加15磅"符合语境,故选F.
(4)E.标题归纳题。根据本部分小标题"Eating right(正确饮食)"以及上文中"•Don't eat desserts full of sugar;have fruit after dinner.( •不要吃含糖的甜点;晚饭后吃水果)"可知,本段主要是关于健康饮食的建议,故E选项"当你学习的时候,尽量不要吃那么多垃圾食品"符合语境,故选E.
(5)A.推理判断题。根据上文"Remember that the "freshman fifteen" can happen to anyone.(记住"新生十五"可能发生在任何人身上)"以及后文"Together,try to eat healthy food and not to eat junk food.Walking,running;and playing sports is always more fun with friends.Help each other and you can have a healthy and happy freshman year.(一起,试着吃健康的食物,不要吃垃圾食品。散步、跑步;和朋友一起做运动总是更有趣。互相帮助,你可以有一个健康和快乐的大一)"可知,上文提到"新生十五"可能发生在任何人身上,后文则提到了一起和互相帮助,可推测本句是在说明一起保持健康饮食的人,A选项中friends对应后文中friends。故A选项"和你的朋友谈谈"符合语境,故选A.
