XV. Food plays a very important part in our life. Read the text and learn how it all happens. Then retell the text. How it Happens.

I like to eat, I like bread and pears and celery. I like carrots and chicken and potatoes and hamburgers. I like orange juice and milk and tomato juice. What do you like? Good food makes you strong and healthy. It gives you energy and helps you grow. Your body uses some kinds of food to make strong bones and hard teeth. It turns other food into solid muscles. It uses some of the food you eat to keep you warm. In the morning you may eat scrambled eggs or cereal. You may drink orange juice or hot chocolate. In a few hours your body has digested the food. Then your blood begins to carry the tiny food molecules to your muscles to make them stronger, to your bones to make them harder, to every part of your body to give you energy and help you grow.

XVI. What should people do if they don’t want to be fat? Read the text and write a letter to your friend who likes to eat fast food. Fat Farmers.

A lot of people are fat. Many of them are teenagers. In the USA some young people go to special summer camps called "fat farms". The campers are not allowed to chocolate, hamburgers, hot dogs or the snack food. They eat fresh fruit, vegetables, fish and brown bread. But why are these teenagers fat? All over the world, young people are eating more and more snacks and fast food and fewer traditional meals. It isn't good to eat a lot of fast food. It is high in salt, sugar and fat. Some chips, for example, have 40% fat. This extra, fat can make you fat. Of course, our bodies need some fat and sugar, and a little fast food won't hurt us. But a lot of fast food is bad for you.

VXII. Read the text " Healthy Henry". " Healthy Henry".

Henry is a clerk in an office in town. He's also a health freak. He wants to live to be a hundred, so health is very important to him. He gets up at five o'clock in the morning and lifts weights for thirty minutes. For breakfast he eats spinach and a raw egg with garlic and chili pepper. It tastes disgusting, but he thinks it's good for him. Then he runs for an hour in the park, even if the weather is bad. He leaves for work at seven o'clock. He never goes by bus or by train and he thinks that cars are extremely dangerous. So he walks everywhere - with a mask over his nose and mouth. He also wears a uniform which he designed to protect himself from dust and dirt. At the office he washes his hands ten times a day and he wears gloves to pick up the telephone in case it's dirty. He takes his lunch to work with him. He eats fifteen sunflower seeds and one onion. He is sure that the lunch which the firm provider, isn't good for him. After work he rushes home to water the plants. He has hundreds of plants, because they provide oxygen. In the evening he sometimes listens to the radio, but he never watches television because it might damage his eyesight.

On Monday he goes to a deep breathing class and on Thursday he goes to a vegetarian cookery class. He rarely goes to the cinema or to the theatre - there are far too many germs. He goes to bed early. In summer he sleeps in a tent in the garden. At the weekend he goes camping in the country, but he never sits in the sun. On the first day of every month he goes to the doctor's, just to make sure that he isn't ill. After all, he doesn't want to find himself in hospital.
