The passage tells us that ______.

are of the need to change their eating habit, because much of the food they eat, particularly processed foods, is not good for the health. Consequently, there 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 matter. 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 amount -- but not the 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 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. 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 this 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 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 contains large quantities of unrefined flour and vegetables, certain diseases are comparatively rare. Hence the emphasis is placed on the eating of wholemeal bread and more vegetables by modem experts in "healthy eating".

This passage is mainly concerned with ______.

A．people's growing interest in natural foods

B．natural food and health diet

C．the importance of fibre in foods

D．harmful effects of sugar

Directions: Read the following three texts. Answer the questions on each text by choosing A, B, C or D. Mark your answers on ANSWER SHEET 1.

Play is the principal business of childhood, and more and more in recent years research has shown the great importance of play in the development of a human being. From earliest infancy, every child needs opportunity and the right material for play, and the main tools of play are toys. Their main function is to suggest, encourage and assist play. To succeed in this they must be good toys, which children will play often, and will come back to again and again. Therefore it is important to choose suitable toys for different stages of a child' s development.

In recent years research on infant development has shown the standard a child is likely to reach, within the range of his inherited abilities, is largely determined in the first three years of his life. So a baby' s ability to profit from the right play materials should not be underestimated. A baby who is encouraged and stimulated, talked to and shown things and played with, has the best chance of growing up successfully.

The next stage, from three to five years old, curiosity knows no bounds. Every type of suitable toys should be made available to the child, for trying out, experimenting and learning, for discovering his own particular ability. Bricks and jigsaws and construction toys; painting, scribbling 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 years -- the child is at school. But for a few more years play is still 'the best way of 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 and 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.
