One of my biggest fears is spiders. I do not like them since childhood. Once I pick berries in the forest and a spider crawled into my boots. I was very scared. Another image of a spider scares me. He has long legs and a small body. But I understand that this spider is nothing I can do. This myself and calm.

Один из самых моих больших страхов это пауки. Я их не люблю еще с детства. Однажды я собирал ягоды в лесу и паук залез ко мне в сапог. Я тогда очень напугался. Еще меня пугает образ паука. У него длинные ноги и маленькое туловище. Но я понимаю что этот паук ничего мне не может сделать. Этим я себя и успокаиваю.  

My Ideal School would be outside the city near a forest or a river, because the noise of traffic could disturb students at the lessons. When you enter the school yard you can see poplar trees and beautiful flowers. Children will be able to relax during the break, breath of fresh air. To the right of the school building will be a big playground. The school will be has a large room for lessons in various sections, such as dance, aerobics, gymnastics and much more. There will also be a swimming pool and various trails for cyclists and athletes.
