Today , I found out something about my brother that could get him into a lot of trouble. I’ m not sure whether to tell mum and dad.
Although william and I are almost 18 , 小题1:妈妈和爸爸仍然对我们要求很严格。Recently , William has begun wearing some strange clothes, and he looks quite different from before.小题2:The other day I saw him smoking in his room , with two of his friends, Jack and Sean .小题3:I know mum and dad would be angry with me if they knew that I had kept this secret for them . 64.也许我应该告诉他们, so they would’t blame me for keeping a secret.小题4:However, I don’t think william will live at home for much longer as he’s planning to go to university soon, 小题5:His grades are still good. It seems that his behaviour hasn’t hurt his studies . Maybe I should just keep my mouth shut.what should I do?
