Every person has problems.

We often have many problems in school. We are given a lot of homework, we often do not understand some topics  at the lesson, or what is worse, we have conflicts with friends.

We also have a lot of problems with adults. Adults often do not understand us, make us do what we do not want to do at the moment. My problem is that I don't have free time enough to play computer games and I sit late hours. In the morning I always feel like sleeping but my parent wake me up... They even have taken my mobile phone because of that. And I am angry with them, though I understand that I must be angry with myself.

We sometimes have misunderstandings with friends. Sometimes we quarrel or even fight, because of mere trifles, but we know if a friend is a true one, he will always help you in a difficult situation.

In order not to fall into depression, in all these cases, you need to try to treat your problems from a positive point of view and look at the situation from another point of view, because in fact, if you try to do your best, you can soon find a solution to any problem. So, if you have a problem, follow my advice and I hope all problems will soon be solved.

Cobras are among the best-known snakes. It's a reptile. It is very dangerous, because it has poison in the teeth. They say, a large king cobra has enough poison in one bite to kill 20 human beings or an elephant. 
The Cobra is famous for its hood, which is formed when a snake gets angry and is ready to attack. 
Cobras can be found mainly in Africa and Asia. They typically live in hot, tropical areas.They like to spend time underground, under rocks and in trees.
They come in different colours: yellow, brown and black. Cobras eatmice, rats, rabbits, lizards, snakes, eggs and birds, but they can easely live without eating for days or months. 
Like other snakes, cobras  do not hear, they are death, but they cansense the ground vibrations.
Cobras lay eggs. They build nests for their eggs and guard them very carefully until babies are born.
It's interesting to know that cobras smell their prey using their tongue.
