     I'm Leo. There is a great artist in my family. She is Lisa. Lisa likes drawing a lot. Here are her three drawings.

    There is an animal in the first drawing. It has two big eyes, a big mouth and two small ears. It has long arms and long legs. It is black and white. There are some apples in its hands. It looks very happy. What is it? I don't know, but Lisa says it is a panda.

    There is a woman in the second drawing. She is thin. She has straight blonde hair, a small mouth, a big nose and two big eyes. She looks angry. Who is she? Lisa says she is our mom. But Mom has curly blonde hair, small eyes and a small nose.

    There is an animal in the third drawing, too. Its head is an apple. Its hair and tail are leaves. It has a long mouth, and it is a banana. Its two legs are carrots. What is it? Lisa says it is a horse, but it doesn't look like a horse.

    Lisa is really a great artist, isn't she?
