Natural foods, for example, vegetables, fruits and grains which have been grown in soil that is 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 farms, for ex- ample, 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 non-essential 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 an additive: 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 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 vegetable. It is interesting to note that in countries where the national diet contains large quantities of unrefined flour and vegetable, certain diseases are comparatively rare. Hence the emphasis placed on the eating of wholemeal bread and more vegetables by modern experts on healthy eating. Recently, some people are interested in natural foods because ______. A．these foods are fresh and sweet B．they want to change their eating habits C．these foods do not contain chemical additives and have not been affected by chemical fertilizers D．they don't like the processed foods

I can pick a date from the past 53 years and know instantly where I was , what happened in the news and even the day of the week. I’ve been able to do this since I was four. I never feel overwhelmed with the amount of information my brain absorbs my mind seems to be able to cope and the information is stored away realy. When I think of a sad memory, I do what everyone does- try to put it to one side. I don’t think it’s harder for me just because my memory is clearer. Powerful memory doesn’t make my emotions any more acture or vivid. I can recall the day my grandfather died and the sadness I felt when we went to the hosptital the day before. I also remember that the musical paly Hamopened on the Broadway on the same day- they both just pop into my mind in the same way.
