5.By now,most people know they should be eating more vegetables.But are there ways to get more from the vegetables you already eat?A research shows that when it comes to vegetables,it's not only how much we eat,but also how we prepare them,that decides the vitamins(维生素) and other nutrients(营养物) that enter our body.
Many studies show that people who eat lots of vegetables have less heart disease,and eye problems and even cancer.But raw(生的) vegetables are not always best.The researchers found that 198Germans who eat raw food were short of lycopene(番茄红素),the matter found in tomatoes and other red vegetables."There is an idea that raw foods are always going to be better,"says Steven K.Clinton,a professor at Ohio State University."For fruits and vegetables,sometimes a little bit of cooking can be helpful."
A number decide how the vegetables do good to people's health before they reach the table,including where and how they were grown and stored before being bought.No single cooking way is best.Some nutrients are easily lost in cooking if they are cooked in different ways.
Vitamins C and B are often lost.In January,another report said that boiling was better for carrots than frying(油炸) or serving them raw.Frying was the worst way to cook.
What cooked with the vegetables can also be important?When the vegetables are cooked with fat,the diners can get more nutrients.Fat can also make the taste of vegetables better,meaning that people will eat more of them.Putting some other things will make it taste better-a little salt-can make the food taste better.

分析 现在,大多数人都知道他们应该多吃蔬菜.但是你有办法从你已经吃的蔬菜中获得更多我们身体所需要的东西吗?一项研究表明,当谈到蔬菜的时候,它不仅是我们吃了多少,而且我们如何准备,以使维生素和其他营养物质进入我们的身体.
许多研究表明吃大量蔬菜的人得心脏病的少,眼睛问题甚至癌症也少有发生.但原生态的蔬菜并不总是最好的.研究人员发现,198个德国人吃生的食物以至番茄红素减少,这种物质在西红柿和其他红色蔬菜中被发现.有一种观点认为生的食物总是会更好,俄亥俄州立大学教授Steven K.Clinton说,对于水果和蔬菜,有时稍稍烹饪一下是很有益的.蔬菜在到达餐桌前决定蔬菜如何有益于人们的健康.包括在购买之前在哪里以及如何成长和储存.没有一个单一的烹饪方式是最好的.如果烹饪方法不同,一些营养物质很容易在烹饪中丢失..
维生素C和B经常失去.在一月,另一份报告说,煮的胡萝卜要比油炸的或者生的胡萝卜更好一些.煎炸烹调是最糟糕的方式.
用什么烹调蔬菜也很重要.当蔬菜和脂肪一起烹调时,食客可以得到更多的营养.脂肪也可以使蔬菜的味道更好,意思是人们会吃的更多.加一些其他的东西会使它的味道更好--加一点点盐可以使食物味道更好.
解答 28.C.细节理解题.根据The researchers found that 198 Germans who eat raw food were short of lycopene(番茄红素),the matter found in tomatoes and other red vegetables.可知,调查表明长期食用生鲜蔬菜的人体内缺少lycopene.故选C.
29.D.细节理解题.根据A number decide how the vegetables do good to people's health before they reach the table,including where and how they were grown and stored before being bought.可知AB两项都能影响蔬菜的食用效果;从第一段but also how we prepare them,可知烹饪方法也有影响,而文中没有提到蔬菜价格的问题.故选D.
30.A.推理判断题,根据When the vegetables are cooked with fat,the diners can get more nutrients.Fat can also make the taste of vegetables better,meaning that people will eat more of them.Putting some other things will make it taste better-a little salt-can make the food taste better.可知做菜时放点肉和盐,可以使蔬菜更美味,营养更易吸收,但不会增加蔬菜本身的营养.因而排除BCD三项.故选A.
