hi how are you. I'm a mexican and I don't know how to use the first conditional so I will deliver you an example " My uncle is a writter.His novels don't sell very well" so this is my example please answer me as soon as posible.
With your facts, I can offer these:
If my uncle doesn't write better, his novels won't sell.
If my uncle doesn't sell more novels, he won't be a writer for long.
