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(咨詢)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 文章主要講述了怎么有效的做到減肥,控制體重.
解答 32.D 細(xì)節(jié)題.根據(jù)第四段第四句 All the subjects were told to increase physical activity and start on a low-calories diet 可知所有人員都要增加鍛煉,開始攝入低熱量的食物.D項意為"提高人體活動",符合題意.故正確答案為D.
33.A 推斷題.結(jié)合第四段中第六句 after six months…和第七句 Eighteen months later…可知實(shí)驗總共進(jìn)行了6加18共24個月.A項意為"實(shí)驗大概持續(xù)了兩年",符合題意.B項,"120多名男性參加了實(shí)驗".根據(jù)第四段第一句 The study involved 470 subjects 和第三句 Over three-fourths of the subjects were women 可知參加實(shí)驗的女性數(shù)量多于總數(shù)470人的四分之三,因此參加實(shí)驗的男性少于四分之一,即少于120人.B項表述錯誤.C項,"健康咨詢幫助減肥6千克".根據(jù)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,只有與健康專家談過話的人減肥了6千克,使用健康追蹤器的人只減肥了3.5千克,所以并不是所有有健康咨詢的人都減肥了6千克,不符合題意.D項,"佩戴健康監(jiān)測器有利于苗條".文中并未出現(xiàn)相關(guān)信息,不符合題意.故正確答案為A.
34.C 細(xì)節(jié)題.根據(jù)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,處理美國的肥胖問題需要長期有效的治療.C項意為"解決肥胖問題需要長期有效的治療",符合題意.故正確答案為C.
35.B 推斷題.結(jié)合第四段實(shí)驗結(jié)果可知進(jìn)行健康咨詢的小組減肥效果更為明顯,B項意為"暗示定期的健康咨詢對于控制體重很有必要",符合題意.A項,"描述研究人員進(jìn)行試驗".這只是文章部分內(nèi)容,不符合題意.C項,"告訴讀者為了控制體重而佩戴健康監(jiān)測器".這并不是文章目的,不符合題意.D項,"警告女性更可能受體重問題影響".實(shí)驗對象大多數(shù)是女性,但不是文章寫作目的,不符合題意.故正確答案為B.
點(diǎn)評 做這類題材閱讀理解時要求考生對文章通讀一遍,做題時結(jié)合原文和題目有針對性的找出相關(guān)語句進(jìn)行仔細(xì)分析,結(jié)合選項選出正確答案.推理判斷題也是要在抓住關(guān)鍵句子的基礎(chǔ)上合理的分析才能得出正確答案,切忌胡亂猜測,一定要做到有理有據(jù).
