第4题
The United States government publishes guidelines for appropriate nutrient intakes. These are known as the Recommended Dietary Allowances (RDAs) and are updated regularly based on new research in nutrition. RDAs are suggested amounts of calories, protein, and some minerals and vitamins for an adequate diet. For other dietary substances, specific goals must await further research. However, for the U.S. population as a whole, increasing starch and fiber in one's diet and reducing calories (primarily from fats. sugar, and alcohol) is sensible. These suggestions are especially appropriate for people who have other factors for chronic diseases due to family history of obesity, premature heart disease, diabetes, high blood pressure, and high blood cholesterol, or for those who use tobacco. Snacks can furnish about one-fourth of the calorie requirements among teenagers. Those snacks should also provide much of the day's allowances for protein, minerals, and vitamins. Sandwiches, fruit, and milk make good snacks for active teenagers. Food from the food pyramid may be part of any meal. A grilled cheese sandwich or a bowl of whole-grain cereal is just as nutritious in the morning as it is at noon. In addition, a good breakfast consists of any foods that supply about one-fourth of the necessary nutrients for the day. The passage directly states that most of the U.S. population should increase their intake of ______.
A protein B fats C starch and fiber D sandwiches
【正确答案】：C

第11题 The most popular organic gem is the pearl. A pearl is the response of a marine mollusk to the presence of an irritating impurity accidentally introduced into its body; a cultured pearl is the result of the intentional insertion of a mother-of-pearl bead into a live mollusk. Whether introduced accidentally or intentionally, the pearl-making process is the same: the mollusk coats the irritant with a substance called nacre. Nacre is composed chiefly of calcium carbonate. Because very few natural pearls are now on the market, most pearls used in free jewelry are cultured. These include "Biwa" pearls and most other freshwater pearls. Cultured pearls are not easily distinguished from natural pearls except by an expert. Which of the following people could tell the difference between a cultured pearl and an organic pearl?
A Scuba diver. B Fisherman. C Jeweler. D Clerk.
【正确答案】：C 【答案解析】 [分析] 细节题型。 见文章最后一句：Cultured pearls are not easily distinguished from natural pearls except by an expert.只有专家才能区分出天然珍珠和人工培 育的珍珠。珠宝商当然应是这类专家，所以选项 C 正确。A.Scuba diver 戴水 肺的潜水员 B.Fisherman 渔民和 D.Clerk 职员当然不是鉴别珠宝的行家了。

What is the chief component of nacre?
A Sand. B Bead. C Calcium carbonate. D Biwa.
【正确答案】：C
【答案解析】 [分析] 细节题型。 见文章第四句：Nacre is composed chiefly of calcium carbonate.选项 C.Calcium carbonate(碳酸钙)正确。
第13题 The difference between a pearl and a cultured pearl is the nature of the ______.
A color B introduction of the irritating impurity C coating material D irritating impurity
【正确答案】：B
【答案解析】 [分析] 细节题型。 文章第二句(A pearl is the response of a marine„a live mollusk. ) 指出：天然珍珠中的刺激性的杂物是偶然进入体内的(accidentally introduced into its body);而人工培育的珍珠中的杂物是人为加入的(the intentional insertion);所以选项 B 正确。
第14题 Nacre is a substance that is ______.
A mechanically manufactured B the result of laboratory testing C organically secreted by the mollusk D present in the chemical composition of freshwater pounds
【正确答案】：C
【答案解析】 [分析] 推断题型。 文中第三句(Whether introduced accidentally or intentionally, the pearl-making process is the same: the mollusk coats the irritant with a substance called nacre.)说明无论是天然珍珠还是人工：养殖的珍珠，它们 的形成过程是一样的：贝类用一种被称之为珍珠质的物质将刺激性的杂物包裹 住。由此推断出珍珠质 nacre 是贝类 the mollusk 滋生分泌出的，所以选项 C 正确。
第15题 The main idea in this passage is that ______.
A most marketable pearls are cultured because nature does not produce enough of its own to satisfy the market B cultured pearls are of a higher quality than natural pearls
C there are two major methods of pearl-making D a natural "drought" of pearl production is taking place
