Chemistry is very important. It can be called the “central science”, because it connects practically all the other sciences to each other.

Chemistry explains how the world around us works. After all, everything in this world is made out of atoms and chemical compounds. So when we know the basics of chemistry, we can understand how everything in the world interacts.

We actually use chemistry every day, every second. For example, our breathing is a set of complex chemical reactions. Other chemical reactions allow us to move, read, eat and feel.

You need to study chemistry if you choose to work in medicine, engineering, metallurgy, space exploration, developing perfumes and cosmetics, pharmaceuticals, energy and many others.

Химия очень важна. Её можно назвать «центральной наукой», потому что она связывает  друг с другом практически все другие науки.

Химия объясняет, как работает мир вокруг нас. В конце концов, все в этом мире состоит из атомов и химических соединений. Поэтому, когда мы знаем основы химии, мы можем понять, как все в мире взаимодействует.

Мы фактически используем химию каждый день, каждую секунду. Например, наше дыхание - это комплекс сложных химических реакций. Другие химические реакции позволяют нам двигаться, читать, есть и чувствовать.

Вам нужно изучать химию, если вы решите работать в таких областях, как медицина, машиностроение, металлургия, освоение космоса, разработка парфюмерии и косметики, фармацевтика, энергетика, и многих других.

My day usually starts with a jog.And then I have a day of school. My school is close to home, I go there on foot.I love the lessons and sections more than "sweat" at a Desk with textbooks. So today after school I stay for the rehearsal of the team of KVN.The evening I spend at home talking with my parents over dinner, and sleep try to go as early as possible, because I like to Wake up early. Tomorrow is another day of my wonderful life!
Мой день обычно начинается с пробежки.А потом меня ждет день школьных занятий. Школа моя находится недалеко от дома, я иду туда пешком.Я люблю занятия в кружках и секциях больше, чем "потеть" за партой с учебниками. Поэтому сегодня после уроков я останусь на репетицию команды КВН.Вечер я провожу дома,разговариваю с родителями за ужином, а спать пытаюсь ложиться как можно раньше, потому что люблю просыпаться рано. Завтра будет новый день моей замечательной жизни!
