----- Nội dung dịch tự động từ ảnh ----- How to be tidy Sorry to give you bad news: the first rule is that you (1) mustn’t / have to tidy your room before the floor becomes invisible! And I'm afraid that you (2) have to / mustn't leave old bits of pizza in your bedroom for more than a few days, or they will start to smell awful. Don't worry, you (3) have to / don't have to organize your wardrobe like a Benetton clothes shop, but you (4) mustn’t / have to leave your dirty socks under the bed for more than a week! You (5) don’t have to / mustn't be perfect but you (6) must / don't have to try to be tidy if you want to keep your parents happy.
