(注意使用关联词as we all know; unfortunately; in my opinion; what’s more; after all等)Dear editor,
I’m writing to tell you something about rare and endangered animals. As we all know, animals are close friends of human beings. Their existence, especially the existence of rare animals makes the whole world lively and colorful. Unfortunately, we recently heard that rare animals in the zoo couldn’t escape being hurt, even be killed without mercy, at which we can feel nothing but shocked. The reason why it happened is that some people lack understanding about these animals and caring for them. In my opinion, we should pay more attention to the importance of protecting rare and endangered animals. What’s more, we should take active and effective measures to protect them. After all, protecting animals is protecting ourselves. I hope you will find these suggestions useful.
Yours truly,

(注意使用关联词as we all know; unfortunately; in my opinion; what’s more; after all等)Dear editor,
I’m writing to tell you something about rare and endangered animals. As we all know, animals are close friends of human beings. Their existence, especially the existence of rare animals makes the whole world lively and colorful. Unfortunately, we recently heard that rare animals in the zoo couldn’t escape being hurt, even be killed without mercy, at which we can feel nothing but shocked. The reason why it happened is that some people lack understanding about these animals and caring for them. In my opinion, we should pay more attention to the importance of protecting rare and endangered animals. What’s more, we should take active and effective measures to protect them. After all, protecting animals is protecting ourselves. I hope you will find these suggestions useful.
Yours truly,
