Passage Four The American public’s obsession with dieting has led to one of the most dangeroushealth misconceptions of all times. Many television ads, movies, magazine articles, anddiet-food product labels would have consumers believe that carbohydrates (碳水化合物) are bad for the human body and that those who eat them will quickly becomeoverweight. We are advised to avoid foods such as potatoes, rice and white bread andopt for meats and vegetables instead. Some companies promote this idea to encourageconsumers to buy their "carb-free" food products. But the truth is, the human bodyneeds carbohydrates to function properly, and a body that relies on carbohydrates but isexhausted of thisdietary element is not in good shape after all. Most foods that we consume on a daily basis like potatoes and rice are loaded withcarbohydrates. Contrary to popular belief, carbohydrates have many health benefitssome fight diseases such as high blood pressure and heart disease, and others help toprevent cancer and stroke. Cutting these foods out of your diet may deprive your bodyof the many health benefits of carbohydrates. One of the best benefits of carbohydrates is their ability to help to maintain the health of our organs, tissues, and cells. Scientific studies have shown that one type of carbohydrate called fiber reduces the risk of heart disease. Carbohydrates also contain antioxidants (抗氧化剂) , which protect the body’s cells from harmful particles with thepotential to cause cancer. This does not mean that the human body can survive on a diet composed entirely ofcarbohydrates. We also need certain percentages of proteins and fats to maintain healthybodies. But carbohydrates certainly should not be avoided altogether. In fact, the foodpyramid, the recommended basis of a healthy diet, shows that a person should consumesix to eleven servings of breads and grains, as well as three to four servings each offruits and vegetables - all carbohydrate-containing foods. It is easy to see why cuttingcarbohydrates out of a person’s diet is not a good idea. The only way to know what is truly healthy for your own body is to talk to a nutritionist or dietician, who can help you choose foods that are right for you as well asguide you toward a proper exercise program forweight loss, or muscle gain. Theseprofessionals will never tell you to cut out carbohydrates entirely! The bottom line:listen to the experts, not the advertisers! The main purpose of the passage is to
案例分析题Temperatures (温度) around the world are going up year after year. A report shows that the ten warmest years since 1860 all happened after 1987. Of those ten, nine happened after 1990. The report also says the increase (上升) in temperature over the past 25 years is greater than that over the past 1,000 years. Ken Davidson, a world-famous scientist, agrees with the scientific findings that global (全球的) warming is happening just because of what people do on the earth. He says one of the most important reasons for the higher temperatures is the fact that cities are getting bigger and bigger. Studies show that cities are hotter than other places. Reports show that many places around the world have had unusual weather in the past few years because of global warming. Most of Asia, for example, is warmer than before, and in India hundreds of people have even died from the hot and dry weather each year. Parts of Africa have often had unusually heavy rains while other parts of Africa have had unusually dry weather. In parts of Europe, more than 100 people died from heavy rainfall in September 2002. Yet large parts of North and South America had very dry weather in the same year. What does the scientist think is an important reason for the higher temperatures（）
Ironically, a study finds that we’re awful gift-givers precisely because we spend too much time trying to be considerate.We imagine our friends 46 a gift that is impressive,expensive,and sentimental. We imagine the look of happinessand surprise on their faces and the warmth we feel. 47 .But there’s something thatthe most sentimental-gift-givers tend not to think too much about: 48 the gift is practical in the first place. 49 , practicality seems like an enemy of great gift giving. Beautiful jewelry, lovely watches, perfect rugs, finely crafted kitchen hardware: These things50great gifts because they communicate something beyond practicality. Theycommunicate that the giver cares. But do the receivers care Often,no. "Gift receivers would be 51 ifgivers gave them exactly what they requested 52 . attemptingto be’thoughtful and considerate’ by buying gifts they did not explicitly request" to surprisethem, the researchers write. Their clever paper asks givers and receivers to 53 gifts from two perspectives: desirability (e.g. the cost of a coffee maker) and feasibility(e.g. the 54 of the coffee maker).Across several experiments, theyfind that givers consistently give gifts based on desirability and receivers 55 favor gifts based on feasibility .
案例分析题Many people believe they should drink eight glasses of water a day. That is (41) they have been told all their life. (42) a new report says people should drink as (43) water as they feel like drinking. The report does not (44) people how many glasses of water to drink. Instead, (45) says women should get about 2.7 litres (升) of water a day, (46) that men should get about 3.7 litres. In each (47) , that is more than eight glasses. As you might (48) , the report says people need to drink more water (49) they are doing physical (体力的) work. The same is true of those who live in hot weather. These people could need much more water (50) others. 49（）。
