Today is the fifth of July. It’s my father’s birthday. Now Mum is cooking a lot of food for my father in the kitchen. My grandparents are watching a film and drinking juice in the living room. I prepared（準(zhǔn)備） a big birthday cake for my dad early this morning. I think he will like it very much. My grandparents will give a watch to him. What about my mum？ Mum says， “It’s a secret.”
