Où j'en suis dans mon devoir

J'ai écrit mon expression écrite et j'aimerais que vous dites si vous trouvez des fautes et si j'ai bien respecter les poins ci-dessus


One day I read a good novel in my bath but I was so exhausted that I fell asleep. When I woke up my book was totally soaked with water. It is then that I had the idea to invent a book which would resist the water. I inquired and no book which can be read in the bath had been marketed except for some album for child.
To realize this project, I thought of creating an ink which would not soak and a rather thick paper and which does not absorb the water. To find all these constituents I have to appeal to specialists. The ideal would be that in a few years any book could be bought with this bonus.
I suppose that many readers would be happy of this invention. What literary person has not ever dreamed to read in warm water plunged into the foam? Or be allowed float on an inflatable mattress by wasting a book?
Of course the price of these books would be more raised because the paper and the ink will be more expensive. For a book having the 15 dollars price it would be necessary to pay out in 30 dollars.

Merci d'avance
