四级练习2016.04.14


       
       



Increasingly, over the past ten years,people-especially young people-have become aware of the need to change their eating habits,(1)__________________________________________.Consequently, there has been a growing interest in natural foods:foods which do not contain chemical materials and which have not been affected by chemical fertilizers,widely used in farming today.Natural foods, for example, are vegetables,fruit and grain which have been grown in soil that is rich in organic matter.Natural foods also include animals which have been allowed to feed and move freely in healthy grasslands.(2)_________________________________________________.There are battery farms, for example,where thousands of chickens live crowded together in one building and are fed on food which is little better than rubbish.Chickens kept in this way are not only tasteless as food;they also produce eggs which lack important vitamins.What’s more, nowadays fiber is considered to be an important part of a healthy diet.In white bread, for example, the fiber has been removed.But it is present in unrefined flour and of course in vegetables.It is interesting to note that in countries where the national diet contains large quantities of unrefined flour and vegetables,certain diseases are comparatively rare.(3)__________________________________________________.
