单选题Everything living on earth—each plant and animal—needs other living things. Nothing lives alone. Most animals must live in a group, and even a tree or a plant grows close together with others of the same kind. Sometimes one living thing hunts another, one eats and the other is eaten. Each kind of life eats another kind of life in order to live, and together they form a food chain. Some food chains are simple, others are complicated. But all have two things in common-all food chains begin with the sun, and all food chains become broken up if one of the links disappears. All life depends on energy from sunlight. Only plants can use this energy directly. Their leaves are little factories that use sunlight to make food from water and things in the soil and air. Plants in turn feed all other living things. Animals can only use the sun's energy after it has been changed into food by plants. Some animals feed directly on plants, others eat smaller animals. Meat-eating animals are only eating plants indirectly. What about human beings? We are members of many food chains. We eat wheat, rice, vegetables, fruits and so on. We also eat meat and drink milk. This means the sun's energy passes through plant to animal before it reaches us. Nature is a greater thing. Any food chain always produces enough for each of its members if it is left alone. When there isn't enough food for any link in the chain, some of its members die off. So the balance is always kept. But men in their greed and ignorance often break up the food chain and do great harm not only to one plant or animal, but to all the links in the chain. People make seas and rivers dirty. They destroy whole forests and kill many kinds of wild animals and birds. When a river becomes dirty , the fish cannot be eaten. Men eat the fish and get strange diseases. In some places men have no fish to eat any more, because the fish have died off. Each form of life is linked to all others. Breaking the links puts all life in danger.

单选题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 m 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 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 m 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 ".

单选题 The Security Council has the greatest power in the UN. The main function of it is to maintain international peace and restore peace when conflicts arise. Its decisions are binding on all UN members. The Security Council has the power to define what is a threat to security, to determine how the UN should respond, and to enforce its decisions by ordering UN members to take certain actions. The Security Council arranges conferences whenever there is a threat to peace. A representative from each member country who sits on the Council must be available at all times so that the Council Can meet at a moment's notice. The Security Council also frequently meets at the request of a UN member — often a nation with a grievance about another nation's actions. The Security Council has 15 members; five of which hold permanent seats. The Assembly elects the other ten members for two-year terms. The five permanent members ( the United States, Britain, France, Russia, and China) have the most power. These nations were the winning powers at tile end of World WarⅡ, and they still represent the bulk of the world's military might. Decisions of the Council require nine votes. But any one of the permanent members can veto an important decision. This authority is known as the veto right of the great powers. As a result, the decision is effective only when its permanent members can reach an agreement. The Council has a variety of ways it can try to resolve conflicts among countries.

It can send peacekeeping troops into a distressed area. If war breaks out ,the Council can call for a ceasefire. It can enforce its decisions by imposing economic sanctions on a country ,or through joint military action.
