F: Why did Nicola join in the experiments?

参考解析

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。

Deep inside a mountain near Sweetwater in East Tennessee is a bady?of water known as the Lost?Sea.It is listed by the Guinness Book of World Records as the world′s largest underground lake.The Lost Sea is part of an extensive and historic cave system called Craighead Caverns.The caverns have been known and used since the days of the Cherokee Indian nation.The cave?expands into a series of huge rooms from a small opening on the side of the mountain.Approximately?one mile from the entrance,in a room called-The Council Room",many Indian artifacts have been?found.Some of the items discovered include pottery,arrowheads,weapons,and jewelry.For many years there were persistent rumors of a large underground lake somewhere in a cave,but it was not discovered until 1905.In that year,a thirteen-year-old boy named Ben Sands crawled through a small opening three hundred feet underground.:He found himself in a large cave half filled?with water.Today tourists visit the Lost Sea and ride far out onto it in glass-bottomed boats powered by electric motors.More than thirteen acres of water have been mapped out so far and still no end to the lake has been found.Even though teams of divers have tried to explore the Lost Sea,the full extentof it is still unknown.What was found in"The Council Room"?A.A small natural opening.B.A large cave.C.Another series of rooms.D.Many old Indian objects.

共用题干第二篇The Best Way to Reduce Your WeightYou hear this:"No wonder you are fat.All you ever do is eat."You feel sad:"I skip my breakfast and supper. I run every morning and evening. What else can I do?"Basically you can do nothing. Your genes,not your life habits,determine your weight and your body constantly tries to maintain it.Albert Stunkard of the University of Pennsylvania found from experiments that"80 percent of the chil- dren of two obese(肥胖的)parents become obese , as compared with no more than 14 percent of the offspringof two parents of normal weight."How can obese people become normal or even thin through dieting? Well,dieting can be effective,but the health costs are tremendous.Jules Hirsch,a research physician at Rockefeller University,did a study of eight fat people.They were given a liquid formula providing 600 calories a day.After more than 10 weeks,the subjects lost 45kg on average.But after leaving the hospital,they all regained weight. The results were sur- prising : by metabolic(新陈代谢的)measurement , fat people who lost large amounts of weight seemed like they were starving. They had psychiatric problems.They dreamed of food or breaking their diet. They were anxious and depressed;some were suicidal.They hid food in their rooms.Researchers warn that it is possible that weight reduction doesn't result in normal weight,but in an abnormal state resembling that of starvednonobese people.Thin people,however,suffer from the opposite:They have to make a great effort to gain weight.Ethan Sims,of the University of Vermont,got prisoners to volunteer to gain weight. In four to six months,they ate as much as they could. They succeeded in increasing their weight by 20 to 25 percent.But months after the study ended,they were back to normal weight and stayed there.This does not mean that people are completely without hope in controlling their weight.It means that those who tend to be fat will have to constantly battle their genetic inheritance if they want to significantly lower their weight. The findings also provide evidence for something scientists thought was true一each person has a comfortable weight range.The range might be as much as 9kg. Someone might weigh 60~69kg without too much effort. But going above or below the natural weight range is difficult. The body resists by feeling hungry or full and changing the metabolism to push the weight back to the range it seeks.The first paragraph tells us that our weight is determined by________.A:our eating habitsB:our life styleC:our work habitsD:our genes

共用题干The Weight Experiment1. 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. Volunteers have to get prepared for the time in the calorimeter______.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

单选题Bypass surgery has been shown to be effective at helping extremely obese people lose weight. Some patients have lost as much as 300 pounds after undergoing the surgery, thereby substantially prolonging their lives. Despite the success of the treatment, most doctors have not embraced the surgery as a weight loss option.  Which of the following statements, if true, best accounts for the lukewarm reaction of the medical community to gastric bypass surgery?AGastric bypass surgery carries a high risk of serious complications, including death.BObesity is one of the leading contributors to heart disease and hypertension, two leading causes of death.CObesity rates among the American population have been increasing consistently for the last three decades.DMany patients report that losing weight through diets is ineffective, since they usually gain the weight back within six months.EMost health insurance plans will cover the cost of gastric bypass surgery for morbidly obese patients at high risk of heart disease.
