你是什么年级的?我不知道要适应怎样的水平
having a pet can bring us much pleasure. I have a pet ,it is like a member of my family. when i leave home in the morning, it will send my to the door. when i get home in the evening, it will welcome me at the door. if I get home late, it will be worried. really, i feel it is like a baby around me, i look after it and it reward my a lot of fun.
