问题 共用题干The Weight Experiment
1. Nicola Waiters has been taking part in experiments in Scotland to discover why humans gain and lose weight. Being locked in a small room called a" calorimeter"（热量测量室）is one way to find out. The signs above the two rooms read simply"Chamber One"and"Chamber Two",these are the calorimeters:4m by 2m white-walled rooms where human volunteers are locked up in the name of science .Outside these rooms another sign reads.,"Please do not enter-work in progress" and in front of the rooms advanced machinery registers（记录）every move the volunteers make. Each day,meals measured to the last gram are passed through a hole in the wall of the calorimeter to the resident volunteer.
2. Nicola Waiters is one of the twenty volunteers who,over the past eight months,have spent va-rying periods inside the calorimeter. Tall and slim,Nicola does not have a weight problem,but thought the strict diet might help her with training and fitness program. A self-employed communi-ty dance worker , she was able to fit the experiment in around her work. She saw an advert（广告） for volunteers at her gym and as she is interested in the whole area of diet and exercise,she thought she would help out.
3. The experiment on Nicola involved her spending one day on a fixed diet at home and the next in the room.This sequence（次序）was repeated four times over six weeks.She arrived at the cabo-rimeter at 8:30 a. m. on each of the four mornings and from then on everything she ate or drank was carefully  measured.Her every move was noted too,her daily exercise routine timed to the last second. At regular intervals,after eating,she filled in forms about how hungry she felt and sam-pies were taken for analysis.
4. The scientists helped volunteers impose（确立）a kind of order on the long days they faced in the room."The first time,I only took one video and a book .But it was OK,because I watched TV the rest of the time, "says Nicola.And twice a day she used the exercise bike.She pedaled(踩踏 板）for half an hour,watched by researchers to make sure she didn't go too fast.
5. It seems that some foods encourage you to eat more,while others satisfy you quickly.Volunteers are already showing that high-fat diets are less likely to make you feel full. Believing that they may now know what encourages people to overeat,the researchers are about to start testing a high-protein weight-loss diet. Volunteers are required and Nicola has signed up for further sesslons.The experiments show that high-fat diets______.A: the volunteers doB: because she does not have a weight problemC: because the life there can be very boringD: make people overeatE: because she was her own bossF: after passing a high-protein test
选项 The experiments show that high-fat diets______.
A: the volunteers do
B: because she does not have a weight problem
C: because the life there can be very boring
D: make people overeat
E: because she was her own boss
F: after passing a high-protein test
答案 D
解析 本文的主旨是体重试验，主要谈哪些活动可以减轻人的体重。要达到这样的目的，人们就有必要建立专门的热量实验室。第一段详细地介绍了热量实验室的有关情况，比如它的外观、尺寸、用途等。选项C的意思是“热量测量室是什么？”作为第一段的大意最合适，故选C。


第二段主要讲尼古拉作为一名志愿者，在热量测量室进行了多次试验，文章说她到这里来的目的主要不是减肥，因为她没有体重问题，而是看看这里的饮食和活动对她的健身活动如何有益。因为她是跳舞的，她认为通过参加这里的活动会给自己的工作带来益处。选项F的意思是“她为什么来参加试验？”正好概括了这段的主旨大意，所以选F。


第三段的第一句就指出了尼古拉所面对的试验的要点，整段主要介绍了针对她安排的实验的详细情况，这与选项B的意思相符，故选B。


第四段主要介绍志愿者接受试验时如何打发自己的时间，主要是看看电视或看书。选项E中的kill the time就是打发时间的意思，与第四段相符，故选E。


本题考查的是对阐述文章的主旨事实与细节的了解。此句的意思是实验室外面的机器都记录了什么，根据第一段的介绍，显然是志愿者所作的各种活动的情况等，故选A。


本题考查的是对文章细节的了解。此句问为什么尼古拉有时间来参加试验，文章提到她是自由职业者，可以自由支配和安排她的时间，故选E。


本题考查的是对阐述文章的主旨事实与细节的了解，以及时上下文之间的意义关系的理解。此句问的是为什么接受试验者要对在实验室里待上一段时间做好准备，文章也提到了做试验时是很枯燥的，如果接受试验，就要做好如何打发时间的心理准备，选项C补充到原句中意思合适，故选C。


本题考查的是对阐述文章的主旨事实与细节的了解。此句问的是“试验表明，高脂肪的饮食会导致什么？”文章最后一段说，志愿者表示高脂肪的食谱让人感觉吃不饱，所以导致人们饮食过量。因此选D。
