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.”

14.In Paragraph 4, “a fruitless search”means            .

A.an effort with no results                    

B.a search for a diet without fruits

C.a research on fruitless diet                 

D.a diet serving as medicine

15.Many women take it for granted, according to passage that            .

A.a balanced diet can result in being fat

B.staying thin and healthy are both possible

C.lack of variety in diets leads to staying thin

D.vitamins are some kind of subsitutions for food

16.By “if the fuel isn’t there, the spark is useless”,the author means            .

A.carbohydrates, protein and fat are enough to support a human life

B.vitamins and minerals are virtually of no valuew.

C.carbohydrates, protein and fat are as important as vitamins and minerals

应根据何种用途对该两幢房屋进行估价( )

A．根据房屋所有权证上记载的用途进行估价

B．根据估价人员现场勘察结果的现状用途进行估价

C．根据企业改制、资产重组后该两幢房屋拟确定的用途进行估价

D．根据该两幢房屋可以获利最多的用途进行估价

如图17所示的风洞是对许飞机导弹性能进行检测的一种高科技产物，现代汽车的生产也有运用风洞技术进行检没的，如图18所示是小丽所在兴趣小组设计的一个类似于风动的实验装置，他们在桌面上放有许多大小不同的塑料球，测得它们的密度均为，用水平向左恒定的风作用在球上，使它们做匀加速运动（摩擦不计）。已知风对球的作用力与球的最大横截面积成正比，即F=kS，k为一常量。                                                       图17

（1）对塑料球来说，空间存在一个风力场，请定义风力场强度并写出其表达式

（2）在该风力场中风力对球做功与路径无关，因此可引入风力势能和风力势的概念。若以栅栏P为风力势能参考平面，写出风力势能E_P和风力势U的表达式

（3）写出风力场中机械能守恒定律的表达式（小球半径用r表示；第一状态速度为v₁，和P的距离为x₁；第二状态速度为v₂，和P的距离为x₂）
