你这不是完形填空 貌似是改错
My favourite animal is dog. They are very cute. There are many kinds of dogs. Some of them are big and some of them are small, some of them are white and some of them are black. I like the big dogs, like a bulldog, because they can protect me. I don't have anydog yet, because my mum does not like dogs. she think they are dangrous. I Will buy a dog after I become older.
