23、ears research has shown the great importance of play in the development of a human being.

27、and making things; sand and water play; toys for imaginative and pretending play; the first social games for learning to play and get on with others.By the third stage of play development-from five to seven or eight yearsthe child is at school.

28、learning, at home or at school. It is easier to see which type of toys the child most enjoys.Until the age of seven or eight, play and work mean much the same thing to a child. But once reading has been mastered, then books and school become the main source of learning. Toys are still interesting an
29、d valuable, they lead on to new hobbies, but their significance has changed-to a child of nine or ten years, toys and games mean, as to adults, relaxation and fun.（分数：10.00）(1).The writer wants us to understand that a child _.（分数：2.00）A.has to be taught how to playB.likes a toyC.matures through play

Consequently, th
44、ere has been a growing interest in natural foods: foods which do not contain chemical additives and which have not been affected by chemical fertilizers, widely used in farming today.Natural foods, for example, are vegetable, fruit and grain which have been grown in soil and are rich in organic matt
45、er. In simple terms, this means that the soil has been nourished by unused vegetable matter, which provides it with essential vitamins and minerals. This in itself is a natural process compared with the use of chemicals and fertilizers, the main purpose of which is to increase the a-mountbut not the
46、 quality-of foods grown in commercial farming areas.Natural foods also include animals which have been allowed to feed and move freely in healthy pastures. Compare this with what happens in the mass production of poultry: there are battery farm, for example, where thousands of chickens live crowded
47、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.There are other aspects of healthy eating which are now receiving increasing attention from experts on diet
48、. Take, for example, the question of sugar. This is actually a nonessential food! Although a natural alternative, such as honey, can be used to sweeten food if it is necessary, we can in fact do without it. It is not that sugar is harmful in itself. But it does seem to be addictive: the quantity we
49、use has grown steadily over the last two centuries and in Britain today each person consumes an average of 200 pounds a year! Yet all it does is to provide us with energy, in the form of calories. There are no vitamins in it, no minerals, and no fibre.It is significant that nowadays fibre is considered to be an important part of a healthy diet. In white bread, for example, the fibre 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 con
