Помогите пожалуйста с английским языком :(((

Hi /имя друга/,
I'm writing you back as soon as I've got your letter!
It turns out we are in the same shoes with our projects, aren't we?)
I have been doing a really huge project about Egyptian pyramids. Let me tell you about it.
I've got some exciting news for you. There are from 118 to138 pyramids in Egypt left. I've never realized there are so many of them! That's completely amazing.
The most interesting part of my project is the design of the pyramids itself tho.
What really made impression on me was that the Egyptians had built pyramids without any complicated machines, using primitive tools only.
Just imagine, one of the ways of processing stone walls was grinding. I find Egyptian grinding totally incredible. Not a blade of a knife could came in through the brick walls. Like totally impossible!
I came up with the demonstration the quality of that grinding in front of the history class. So I made a mini-copy of a pyramid wall. You should have seen the face of my teacher, while I was showing how it worked. And I couldn't believe it when I got A+ after all.

Keep in touch!
Yours,
