Для этого действуем по формуле Х кг • %/100
Получается 5 • 85/100
Получается 4,25 кг меди
5кг - 4,25кг = 0,75кг олово или 750гр

A. Genetically modified crops have been developed by changing the plant’s genetic structure in order to help the plant resist against different diseases or produce larger harvest. However.

there is no scientific conclusion so far to prove the safety of GM foods for humans We don ’t

know what unforeseen consequences there might be. Most people, prefer not to risk their

health because scientists are not sure if GM food is absolutely harmless or not.



B. Food poisoning is a common, distressing and sometimes life-threatening problem for

millions of people throughout the world. Food poisoning is when someone gets sick from

eating food or drink that has gone bad or is contaminated by bacteria. Depending on the type

of infection, people can even die as a result of food poisoning. According to the Centers for

Disease Control and Prevention, about 16 million people in Britain become ill from the food

they eat, and about 1,000 of them die every year.



C. Experts say that fast food makes people overweight and even obese and elevates the risk of diabetes and cancer. If your food includes hamburgers, chips, hot dogs, pizzas and fizzy

drinks like Coke, Pepsi, Sprite and others, you are facing a serious problem threatening your

health. Such food is full of chemical additives. For example, a can of Coke contains about

eight teaspoons of sugar and artificial sweeteners. Moreover, there is a risk of food poisoning.



D. In North America and Europe people think that a slim woman is healthy and careful about

what she eats. But in many parts of Africa a fat woman is considered beautiful. In central

Africa the girls are sent to fattening rooms where these girls sit, lie and eat. They are given

bowels of food that help them get fat. It is boring to stay in these rooms for so long with

nothing to do, but the girls do not mind. A future husband wants his wife to be fat so other

people will think that the man is rich and he is a responsible man.



E. Do you know a person who has never eaten fast food? Many restaurants sell what is called

“fast” or “junk” food - hamburgers, chips and so on. This food is tasty and cheap. Such food

is very popular, especially with children and teenagers. What is more, fast food saves much

time and effort for busy working people. People don’t have to go to a supermarket, prepare

meals and wash the dishes when they eat out. However, many experts say that fast food is

not healthy.



F. People today are probably more concerned about food than ever before. We worry about

eating foods that contain too much fat and so we cut down on things like meat, bread,

potatoes and dairy products. The problem is that we may also be cutting out good sources of

iron or other vitamins and minerals. Suddenly we start feeling tired and irritable. Eating well

does not mean that you should cut out all your favourite foods; it just means eating sensibly

and trying to avoid too much fast food.



G. Weight problems among children in Britain are increasing. More and more children are over their ideal weight. Obese children are often bullied at school and may have health problems on too much junk food, computer games and TV. So the first Britain’s camp for obese children has been opened. Each morning at the camp, the children do three hours of activities like football, hockey and rugby. After lunch they have lessons on nutrition and cooking. Most kids leave the camp feeling healthier and happier than before.
