对人有益的动物有很多，例如有蜻蜓、青蛙等等。

我们先说蜻蜓吧，它是益虫，它对人的益处可多了。它生活在小池子旁边，捕捉害虫。有些人，捉蜻蜓，捕蜻蜓，捉住后到处卖。我们应给立一个保护蜻蜓法，如果他们再敢捉蜻蜓，捕蜻蜓，就是知法犯法，交给警察叔叔处理。

青蛙也不例外，它也是捕捉害虫的能手，不过，它生活在庄稼附近的池子旁边，有时候，它也到庄稼地，旁边捕捉害虫，人们都称它保护庄稼的好帮手。有的小朋友，到池子旁边，捕捉青蛙，回家后，吃青蛙。我们应该在池子旁边树一个牌子，上面写着“保护青蛙，人人有责”，这样就不会有人捕捉青蛙了。

如果没有这些有益动物，害虫就会增多。这样，连农药和灭害灵都不行了。我们应给共同保护动物。
