【OG20-P565-621题】

According to a study, after a week of high-altitude living, twenty men had slimmed down.The men, middle-aged residents of low-altitude areas, had been taken to a research station at 2,650 meters (8,694 feet) above sea level. They had unrestricted access to food and were forbidden vigorous exercise, yet they lost an average of 1.5 kilograms (3.3 pounds) during their one-week stay. Clearly, the lower availability of oxygen at higher altitudes, or hypobaric hypoxia, can be said to have caused the weight loss, since __________.

Which of the following would, if true, most logically complete the argument?

A

a decrease in oxygen intake has been shown to depress appetite
分析A选项
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

B

the men all participated in the same kinds of exercise during their stay
分析B选项
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

C

the foods available to the men had fewer calories than the foods they usually ate
分析C选项
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

D

exercise at higher altitudes is more difficult than exercise at lower altitudes is
分析D选项
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

E

several weeks after returning home, the men still weighed less than they had before the study
分析E选项
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

题型：explain

原文大意：一项研究显示，在一周的高海拔生活之后，20个人瘦了。这些中年的低海拔地区的人被带到2650米的地方，没有限制饮食并禁止强烈运动，但还是平均减少了1.5公斤。很显然，高海拔的缺氧带来了减肥，是因为？

逻辑链：

oxygen---weight loss---no diet or exercise

High-altitude

选项解析：

A.缺氧会抑制食欲。因此虽然没有限制饮食但自觉吃的少了，带来减重，可以解释，正确

B.都做一样的运动，运动导致减重，排除

C.食物是低卡的，说明是食物导致减重，排除

D.高原运动更难，无关比较，排除

E.回家之后依然更轻，回家之后，无关，排除

这道题是说在高海拔地区不限食物供应但是禁止剧烈运动的人在高海拔地区成功减重。得出高海拔地区的氧气稀薄能够导致减重，问为什么氧气稀薄能导致减重，那么就必须要在围绕氧气稀薄和减重之间建立一个关系，这个关系只有A能说明，其余选项均为无关选项。

原来2650米这里是高海拔区域。。。

能得到食物和能增重之间有个gap，就是这人要把得到的食物吃下去，要佐证这个结果就是说明得到再多的食物也吃不下去。

逻辑链;a week of high-altitude living （unrestricted access to food and were forbidden vigorous exercise）-->men had slimmed down-->HH caused the weight loss.A 搭桥，HH可以降低食欲，减肥；B 参加锻炼，否定前提；C 食物卡路里低，但无限量，所以不能解释，且与HH无关；D 前提说了不能锻练，无关；E 试验过后，无关
