good health is very important for every person. moreover, there is nothing more important than health. wise people even say: “health is above wealth”, because if you don’t care of your health, you can’t study or work properly.
unfortunately, having perfect health is almost impossible nowadays. due to highly polluted environment people suffer from many diseases.
the best way to stay healthy is to do regular morning exercise, to eat healthy products, to sleep at least 8 hours a day and to quit bad habits. the good thing is that people are becoming more health-conscious. in my opinion, the number of smoking and alcohol drinking people is decreasing in our country. this is happening because people started to understand how dangerous these two bad habits are. obesity is another health problem. people, who eat lots of fattening food and do almost no exercise, are often overweight. a healthy diet involves many fruit and vegetables, seafood and wholegrain products. salt, sugar and fat should be avoided. excessive dieting can be also dangerous. some people refuse to eat meat and become vegetarian. however, doctors say that meat is an excellent source of good nutrition.
to my mind, one of the best ways to stay healthy and fit is to go in for various sports. my favourite sport is swimming. i spend a lot of time in the swimming-pool. i think it revitalizes my body and gives me energy for the whole day. other sports i enjoy are cross-country skiing and figure-skating. to stay healthy, it is also important to spend lots of time in the open air. it is especially useful to go for a walk before going to bed.
following these simple rules regularly is the only way to promote our health.
1)machine это как общая машина больше. engine - двигатель.
2)это механичный, а техничный больше к технике. (это сложно объяснить)
3)Electronic is usually used to describe something that runs on electricity, such as a computer, television, phone. Electrical tends to describe something that contains/moves electricity, like a power cable or charger. Electric is used to describe something that isn't usually run on electricity, but it can be, like an electric screwdriver, electric guitar. (Только так могу сказать на примерах)
4)слово discover мы используем, когда находим что-то новое. То есть это уже существовало до нас, а мы только обнаружили это. Например: Ученые открыли новую бактерию (они ее не создали сами, а просто обнаружили ее существование). Слово invent мы используем, когда изобретаем что-то новое.
5)дивайс - техника.
6)fix - чинить что т овроде машины. correct - использовать типо исправлять ошибки и тд.
