Text 3 Increasingly, over the past ten years, people—especially young people—have become aware of the need to change their eating habit, because much of the food they eat, particularly processed foods, is not good for 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 fanning 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 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 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 whole meal bread and more vegetables by modem experts in "healthy eating". Which of the following is a reason for people’s growing interest in natural foods
Thousands of writers in Los Angeles and New York went on strike this week, risking their incomes and careers. They want more money for their work when it is used online than Hollywood studios are willing to pay. Because the strike is over matters of principle, not just dollars and cents, it could last for months. The immediate effect was to shut down late-night talk shows, including "Late Show with David Letterman" and "The Tonight Show with Jay Leno".Media companies argue that the market has become increasingly competitive and uncertain for many reasons. including internet piracy and tumbling box-office receipts. They want to cut writers’ income from "residuals", which are payments made when a TV show is re-used. The writers are determined not to repeat the mistake they made in 1985, when they listened to the studios’ plea that home video was an unproven new market and agreed to a residual payment of 0.3%, which translates into about four cents for each sale of a DVD—or one-tenth of what DVD-box manufacturers get. The writers now want a residual payment of 2.5% for re-use of material online and on mobile phones.The studios say that internet delivery is the same as home video, so the old rate still applies. And they refuse to pay anything to writers when content is streamed over the internet free to viewers, supported by ads, because this is merely "promotion". Both sides made last-minute concessions on traditional-media payments. But because new-media rights are so critical to the future earnings of writers and studios, neither was willing to compromise.Who will suffer the most "The strike won’t affect most studios unless the writers stay out three to five months," says a senior executive at a media conglomerate. Because writers on reality and animation programmes are not unionised, the networks will be able to switch to other forms of programming; sport will fill the gaps, too. But Moody’s, a credit-rating agency, reckons that a strike lasting into late 2008 would have a serious financial impact. Broadcast networks and premium-cable channels would be hurt most, because they rely most on first-run scripted shows. Why did writers make such mistake in 1985（）
