нужно составить текст

Every subject, learning at school, is important for us. But , personally, I'm not sure, everyone needs to learn biology or history. There are some subjects, which we all should know.

In my opinion, one of the most important school subjects is the Russian language. We live in Russia so we must know our native language clearly. As we all know, Maths is also very important subject. We use our computing abilities in everyday life and we certainly need it to know.

After all, I can suppose that every of the subjects is important for one or another pupil, but the most important are the Russian language and Mathematics
