How to eat healthfully can be espeically complex for working women who often have neither

How to eat healthfully can be espeically complex for working women who often have neither the desire nor the time to cook for themselves (or for anyone else). Registered dietitian(营养专家)Barhara Morrissey suggests that a few simple rules can help.
“Go for nutrientdense foods,”she suggests, “foods that contain a multiple of nutrients. For example, select whole wheat bread as a breakfast food, rather than coffee cake. Or drink orange juice rather than orange drink, which contains only a small percentage of real juice-the rest is largely colored sugar water. You just can’t compare the value of these foods, the nutrientdense ones are so superior, ”she emphasizes.
Morrissey believes that variety is not only the spice of life—it’s the foundation of a healthful diet. Diets which are based on one or two foods are not only virtually impossible to keep up the strength, they can be very harmful, she says, because nutrients aren’t supplied in sufficient amounts or balance.
According to Morrissey, trying to find a diet that can cure your illnesses, or make you superwoman is a fruitless search. As women, many of us are too concerned with staying thin, she says, and we believe that vitamins are some kind of magic cure to replace food.
“We need carbohydrates, protein and fat—they are like the wood in the fireplace. The vitamins and minerals are like the match, the spark, for the fuel,”she explains. “We need them all, but in a very different proportions. And if the fuel isn’t there, the spark is useless.”

(答案→)12-16 CBADD 解析：12.C 从第一段可以知道职业妇女忙，对做饭不感兴趣，从第一段的“have neither the desire nor the time to cook for themselves”(即没有愿望也没有时间为她们自己做饭)可以看出C项正确。13.B 橘汁和橘汁饮料的区别在于橘汁是自然的，有营养的，是直接从橘子中来的。橘汁和橘汁饮料的区别在第二段中曾经谈到过，即橘汁饮料“contains only a small percentage of real juice—the rest is largely colored sugar water”(只包含很少比例的真正橘汁——其他大都是加了色素的糖水)。因此，相对而言，橘汁是natural, nutritious and prepared from oranges(天然的、有营养的、直接从橘子中来的健康饮料)。14.A a fruitless search 意思为“没有结果的努力”，文中第四段谈到“试图寻找一种可以包治百病，又能使你成为超人的食谱是徒劳的”。因此，a fruitless search表示毫无结果的努力。fruitless的引申意义为没有结果的，徒劳的。15.D 许多妇女想当然地认为维他命是一种食物的代替品。文中第四段提到“As women,\:we believe that vitamins are some kind of magic cure to replace food”。16.D 通过引用“要是没有燃料，光有火花是不行的”。作者的意思是没有碳水化合物，蛋白质和脂肪，维他命和矿物质没有用处。文中最后一段在谈到碳水化合物、蛋白质、脂肪和维生素、矿物质的关系时，作者将碳水化合物、蛋白质、脂肪比作木材、燃料，维他命和矿物比作火柴、火花。引用专家的话说，“要是没有燃料，光有火花是不行的”

对的，就是这个意思
