Re: can somebady fix my essay please?
Welcome to the forums, noamm.
The reason it's important to give correct information in your profile is that it helps us help you better. It's very clear your native language is not American English.
Your essay is full of grammatical errors.
But there are also two questions that have nothing to do with grammar:
What do you mean by it being a "stealing tool" and what is the source of your idea that there is a dangerous amount of radiation in using a phone?
The other thing you need to understand is that we can't help you with any assignment you are going to turn in to your teacher. Your teacher must see what you can do, not what we can do.
After you submit it, if your teacher makes comments you do not understand, you can ask us here.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
