My Animal Friend
I have a lovely animal friend. It is a little dog named Doudou. It is black and white with big round eyes. It is very cute and friendly, and it is my best friend at home.
Doudou is very smart. It lives in my home and eats dog food every day. It also likes to eat small bones. It can run very fast and it can play with a ball well. When I come back home from school every day, it always runs to the door and wags its tail to me. Sometimes it plays with me in the park, and it is never shy with me. It is very friendly to my family too, and everyone in my family loves it.
Doudou is not only a little dog but also my closest animal friend. I look after it carefully every day—feed it, wash it and play with it. I will love it forever and it will be my friend for a long time.
3. 范文示例(主题二:保护野生动物)
Protect Our Wild Animal Friends
Wild animals are our best friends. They live with us on the earth and make our world more colorful. But now many wild animals, like pandas and tigers, are in great danger. They lose their forest homes and don’t have enough food to eat.
What can we do to protect them First, we mustn’t hurt or kill any wild animal. It’s wrong to do that. Second, we should protect their homes. We can’t cut down too many forests and we mustn’t pollute the ocean or river, because many animals live there. Third, we don’t feed wild animals when we see them in the forest, and we can tell our parents and classmates to love and protect wild animals with us.
Protecting wild animals is protecting our earth. They are an important part of nature. Let’s take action now to save our wild animal friends. I believe our world will be more beautiful with all kinds of animals living happily on the earth.
