Ну я так понял,что каждое число больше предыдущего на 1. Исходя из этого 199+199+1=399. Если не правильно,то извини

Переведите пожалуйста текст, как он читается ( Например Май нейм из Влад) My name is Vlad, I am Fifteen years old. I study at school number seventy five. My school is a three-storeyed building with a lot of classrooms, where we learn different subjects. The classrooms for the primary school are on the first floor and the classrooms for the high school are on the second and third floors.

My school has a good reputation in the city. I study at this school for quite a time. That is why I know every corner of our school building very well. By the way, speaking about the building itself I should say that it looks ordinary enough. My school looks like dozens of others built at about the same time. When you enter my school, you find yourself in a big beautiful lobby with decorated walls. Here one can see the cloakrooms and some corridors leading to the school gym and to the school canteen.
Our school is more or less well-equipped. There are special laboratories to study sciences like chemistry or biology; computer class. Besides, we have a gym and a carpenter’s workshop.
On the second floor there are a library and Assembly Hall which is large and beautiful. Different events are often held there.
As for teachers, they are hard-working, intelligent and dedicated. They do their best to give us as much knowledge and I appreciate this.
