　　Passage 1 (選自大綱樣題)

　　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'(熱量測量室)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.

　�、� 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. A self-employed community dance worker, she was　able to fit the experiment in around her work. She saw an advertisement for　volunteers at her local gym and as she is interested in the whole area of diet　and exercise, she thought she would help out.

　�、� 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 at 8:30 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.

　�、� 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. 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 sessions.

　　A. What does the calorimeter look like inside?

　　B. What programme was designed for the experiment?

　　C. What is a calorimeter?

　　D. What kind of foods are to people’s taste?

　　E. How do the volunteers kill the time?

　　F. Why did Nicola join in the experiments?

　　【答案】F

　　【解析】第二段主要介紹了Nicola自愿參加這一實驗的意圖和目的，雖然沒有超重問題，但出于對飲食調節(jié)和身材的保持，她選擇加入這一項目。

　　18. Paragraph ③

　　【答案】B

　　【解析】該段的第一句話是主題句The experiment on Nicola involved her spending one day on a　fixed diet at home and the next in the room.即：實驗所涉及的內容、具體的要求和環(huán)節(jié)。

　　19. Paragraph ④

　　【答案】E

　　【解析】段首句往往是主題句，首句說明科學家?guī)椭�志愿者設定一個日程表來打發(fā)在密室里的時間。后面介紹了看電視、看錄像、看書、騎單車等活動。

　　【答案】D

　　【解析】第五段的首句出現(xiàn)了foods一詞，從剩余的兩個選項A和D中很明顯就能選出D。第五段主要介紹了什么食物適合人的胃口。

　　【單選題】Decide which of the statements can best summarize the　　following passage.Celebrities will always have a large influence on society. The　　influence they have on twitter is incredible. Twitter is an easy way for fans to　　connect with their favorite celebrity and many celebrities are taking advantage　of Twitter's popularity. Every celebrity tweet starts a firestorm of retweets,　　replies, and discussions about what a celebrity just tweeted. A good example of　　this is that the trending topics often revolve around a celebrity or something　　that a celebrity recently tweeted. Celebrity tweets also become news in the　　world of celebrity news. Celebrities now use Twitter to communicate with the　　public instead of issuing statements, and also use their accounts to dispel　　rumors, make announcements, and promote their movies, albums, or books.　　Moreover, because there are so many celebrity tabloids(小報)，simple tweets about　　their everyday lives will also become front-page news.

　　A. Celebrities' use of　　tweet

　　B. Politician's influence on tweet

　　C. Tweet's popularity

　　D. New　　organizations' understanding of　　tweet

　　【答案】A

　　【解析】本題考查概括段落大意。本段出現(xiàn)頻率最高的詞是celebrity，本段一直在講名人如何使用微博，故選A。【知識點】概括段落大意
