问题 共用题干The Weight Experiment
Nicola Walters 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.
1. 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 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 Walters is one of twenty volunteers who,over the past eight months,have spent varying periods inside the calorimeter. Tall and slim,Nicola does not have a weight problem,but thought the strict diet might help with her training and fitness programme.As a self-employed community dance worker,she was able to fit the experiment in around her work .She saw an advert for volun- teers at her local 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 was repeated four times over six weeks.She arrived at the calorimeter at8:30 am 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 samples were taken for analysis.
4. The scientists help volunteers impose a kind of order on the long days they face 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.Volun- teers 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 ses-  slons。The machinery outside the calorimeters records everything______.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 machinery outside the calorimeters records everything______.
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 A
解析 本文的主题是体重实验，主要谈哪些活动可以减轻人的体重。实验室里有专门的热量测量室。第一段主要介绍热量测量室的有关情况，选项C的意思是“热量测量室是什么？”作为第一段的小标题最合适，故选C。


第二段主要讲Nicola作为一名志愿者，在热量测量室进行了多次实验，文章说她到这里来的主要目的不是减肥，而是看看这里的饮食和活动对健身如何有益，因为她自己是搞跳舞的，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 “她为什么来参加实验？”正好概括了这段的意思，所以选F。


第三段主要介绍针对Nicola安排的实验的详细情况。与选项B的意思相符，故选B。


第四段主要介绍志愿者接受实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，与第四段意思相符，故选E。


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，显然是志愿者所做的各种活动的情况等，故选A。


此句问为什么Nicola有时间来参加实验，文章提到她是自雇的社区跳舞工作者，可以自由安排自己的时间，故选E。


此句问的是为什么志愿者要对在实验室里的时间做好准备，文章也提到了做实验时是很枯燥的，如果接受实验，就要做好如何打发时间的心理准备，选项C补到句子中意思合适，故选C。


题句问的是实验表明，高脂肪的饮食会导致什么？文章最后谈到，志愿者发现实验室里安排的这些高脂肪食物让人感觉吃不饱，所以导致人们吃得过多。因此选D。
