Correction of the 1st English – Exam

I was very happy when I saw your letter.
But I was very shocked about Jason. Has nobody told him about the dangers of drugs?
If he keeps on taking drugs, maybe he will die. Or he could have a brain damage or he could have hallucinations.
But you should know it and don’t try it please.
There are some theories, why people take drugs. And you fit 3 of them. Jason wants you to take drugs too so it is the “evil pusher” theory. You want to belong to the crowd and so it is the “in – with – the – crowd” theory.
When you take it, then it is the “because – it – is – offered” theory. And this is stupid I think.
At the beginning it won’t do any harm, but later he won’t be healthy any more or he will leave school maybe.
He could have big problems with his organs.
Think of his parents. They would be very sad I think, if anything happened to him.
Don’t you think so?
The future won’t be bright for him.
I think he should attend a rehab clinic and stop taking drugs.
And as to you
You are my Friend and I don’t want you to take drug. Because I like you and I don’t want to lose you.
Think of your family and of your life.
I am sure that you won’t start take drugs, when you think long about your life.
