particle infections disorders contagious the world microscopes 6. Read the text and put each sentence into the correct place. Some pathogens can survive for long periods on nonliving objects. Insects spread some of the most fatal infectious diseases. Many common infectious diseases spread as a result of close contact with a sick person. HOW INFECTIOUS DISEASES SPREAD Infectious diseases can spread in three chief ways. They spread (1) by people, (2) by animals, and (3) by nonliving sources. 1) Such contact frequently takes place through coughing or sneezing, which expels tiny droplets of moisture that may contain pathogens. Diseases that spread largely through coughing and sneezing include colds, influenza, measles, mumps, pneumonia, tuberculosis, and whooping cough. 2) Fleas, mosquitoes, and other insects that feed on blood transmit many serious diseases. Mosquitoes transmit encephalitis, malaria, and yellow fever in this way. In the same manner, fleas spread plague, and lice carry typhus. 3) These microorganisms can be transmitted by clothing, bedding, silverware, and other objects handled by sick people. Certain bacterial infections sometimes spread to hospital patients through contact with such contaminated objects. IV. Speaking 1.

NUTRITION Nutrition is the science that deals with food and how the body uses it. Food supplies the energy for every action we perform. It also provides substance that the body needs to build and repair its tissues and to regulate its organs and systems. A proper diet helps to prevent certain illnesses and aids in recovery from other. Eating a balanced diet is the best way to ensure that the body receives all the food substances it needs. The daily diet should include a certain number of servings from each of five food groups: vegetables; fruit; breads, cereals, rice and pasta; milk, yogurt and cheese; meat, poultry, fish, dried beans and peas, eggs and nuts. Food provides certain chemical substances needed for good health. The substances, called nutrients, perform one or more of three functions: 1. They provide materials for building, regaining or maintaining body tissues. 2. They help to regulate body processes. 3. They serve as fuel to provide energy. There are six main groups of nutrients. Water is the most critical nutrient. One can live without other nutrients for several weeks, but we can go without water for only about one week. The body needs water to carry out all its life processes. Adults should consume about 2—2.5 litres of water a day. Carbohydrates include all sugars and starches. They serve as the main source of energy. The main sugar in food is sucrose, ordinary white or brown sugar. Fructose comes from most fruits and many vegetables. Lactose is found in milk. Foods containing starches include beans, breads, cereals, corn, pasta (macaroni). Fats are a highly concentrated source of energy and they are composed of an alcohol called glycerol and substances called fatty acids. Proteins provide energy and serve as one of the main building materials of the body. Muscle, skin, cartilage and hair are made up largely of proteins. Every cell contains proteins called enzymes, which speed up chemical reactions. Minerals are needed for the growth and maintenance of body structures. Calcium, magnesium, phosphorus are essential parts of the bones and teeth. There are trace elements which include chromium, cooper, fluorine, iodine, iron and zinc. Iron is an important haemoglobin. Vitamins should be supplied daily in the diet. II. Language Development 1. Match the following English words with the Ukrainian ones.
