2014年同等学力申硕考试英语真题与答案（卷一文字版)

　　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!
