题目内容
19.A new study,a project of the researchers from the University of Pittsburgh in Pennsylvania,finds the fitness tracker probably does not help with weight loss.The devices are designed to record your physical activity.They are usually worn around the wrist,where they measure a person's heart rate.The research team looked at two groups of individuals.The first wore a fitness tracker and took part in health counseling(咨询)with experts to consider the best weight-loss plan.The researchers compared this group with people who only got health counseling.
The study found that those only speaking with the health experts lost nearly 6 kilograms,but those using a fitness tracker lost only 3.5 kilograms.John Jakicic,the lead researcher,questioned the use of electronic devices for weight control in place of"effective behavioral counseling for physical activity and diet."
The study involved 470subjects aged between 18 and 35.Some of them were overweight,while others were considered obese(肥胖的).Over three fourths of the subjects were women.All the subjects were told to increase physical activity and start on a low-calorie diet.They had their weight measured once every six months.After six months,researchers divided the group into two parts:one continued with monthly counseling,while members of the other group were given a fitness tracker.Eighteen months later,both groups"showed significant improvements in fitness,physical activity,and diet,"with no major difference between groups.However,when it came to losing weight,the people who only spoke with experts lost nearly twice as much weight.
Jakicic said,"the study's findings are important because effective long-term treatments are needed to address America's obesity."More information is needed,he added,to learn how to best use these devices to change"physical activity and diet behaviors"in adults who want to lose weight.

分析 文章主要讲述了怎么有效的做到减肥,控制体重.
解答 32.D 细节题.根据第四段第四句 All the subjects were told to increase physical activity and start on a low-calories diet 可知所有人员都要增加锻炼,开始摄入低热量的食物.D项意为"提高人体活动",符合题意.故正确答案为D.
33.A 推断题.结合第四段中第六句 after six months…和第七句 Eighteen months later…可知实验总共进行了6加18共24个月.A项意为"实验大概持续了两年",符合题意.B项,"120多名男性参加了实验".根据第四段第一句 The study involved 470 subjects 和第三句 Over three-fourths of the subjects were women 可知参加实验的女性数量多于总数470人的四分之三,因此参加实验的男性少于四分之一,即少于120人.B项表述错误.C项,"健康咨询帮助减肥6千克".根据第三段第一句 those only speaking with the health experts lost nearly 6 kilograms,but those using a fitness tracker lost only 3.5 kilograms 可知,只有与健康专家谈过话的人减肥了6千克,使用健康追踪器的人只减肥了3.5千克,所以并不是所有有健康咨询的人都减肥了6千克,不符合题意.D项,"佩戴健康监测器有利于苗条".文中并未出现相关信息,不符合题意.故正确答案为A.
34.C 细节题.根据最后一段第一句 the study's findings are important because effective long-term treatments are needed to address America's obesity 可知,处理美国的肥胖问题需要长期有效的治疗.C项意为"解决肥胖问题需要长期有效的治疗",符合题意.故正确答案为C.
35.B 推断题.结合第四段实验结果可知进行健康咨询的小组减肥效果更为明显,B项意为"暗示定期的健康咨询对于控制体重很有必要",符合题意.A项,"描述研究人员进行试验".这只是文章部分内容,不符合题意.C项,"告诉读者为了控制体重而佩戴健康监测器".这并不是文章目的,不符合题意.D项,"警告女性更可能受体重问题影响".实验对象大多数是女性,但不是文章写作目的,不符合题意.故正确答案为B.
