    Hi! My name is Ben. I'm 12 years old. I'm very helpful. I usually wash clothes and clean the rooms at home. I always help my teachers at school. And I am a foodie(吃货)，I like ice creams. They are sweet. And potatoes are my favourite vegetables. I like fruits, but I don't like bananas.

    I'm a cool boy，too. I like playing ping-pong，football and I can swim very well. I was afraid of dogs before，but now I have a pet dog. It drinks orange juice every day. It can play with a ball, it's so cute. I like it very much.

    What am I going to be? Mm…I want to be a police officer. Because helping people is fun for me. I will study hard and do more exercise.
