II. Прочитать и перевести текст DIGESTION For life to continue, the body requires fuel in the form of oxygen and food. Respiration provides the oxygen. Our food, however, cannot be utilized by the body in the form in which it is eaten. It must be specially processed by the body before it can be of any use. This special processing is known as digestion. It is brought about by the action on the food of certain substances called enzymes which are made by the body and mixed with the food during its passage through the body. The food we eat consists of protein, carbohydrate and fat. It also contains small quantities of vitamins and minerals. Proteins are found in meat, fish, eggs, milk .and cheese. They are broken down into amino-acids during digestion. Protein is necessary for cell growth and repair. Carbohydrates are found in sweet and starchy foods such as sugar, flour and potatoes. They are broken down into glucose during digestion. Carbohydrates provide body cells with the energy required to perform their functions. Fats are found in meat, fish, dairy products and vegetable oils. The digestive process breaks them down to fatty acids. Fats provide energy and body fat, which is stored in a layer beneath the skin. It acts as a reserve source of energy when needed, and also as insulation which helps maintain body temperature in cold weather. The body requires water for the production of blood, digestive juices, urine and sweat. Many foods contain a large quantity of water but it is still necessary to drink more than a litre of fluid daily. III. Найти из текста английские эквиваленты

VI. Прочитать и перевести текст The food we eat is called our diet. All the constituents of food — protein, fat, carbohydrates, vitamins and minerals — are present in adequate quantities in a normal balanced diet. There is no need to eat excessive quantities of one or the other. Over-eating is dangerous to health as the body only requires a certain amount of energy. Food eaten in excess of the body's energy requirements is stored in the form of fat and thus increases body weight. This is potentially dangerous to health as it puts an extra strain on the heart and circulation and may lead to disease of the heart and arteries, resulting in high blood pressure and heart failure. Thus all the food we eat undergoes digestion by enzymes, which turn it into amino-acids, fatty acids, glucose, vitamins and minerals. Only when it is in this form can it be absorbed into the blood and utilized by the body cells. VII. Перевести предложения, используя слова из необходимого лексического минимума
