动物的英语作文 篇5
There has been a heated discussion in my neighborhood about whether people should keep pet dogs or not.
People who oppose keeping pet dogs believe that not only do dogs pollute the environment but could potentially attack people.
Despite the against side's perspective the for side stands by their opinions----pets make life more interesting and can comfort elders.
Frankly I think both sides have valid points. Dogs can make great companions whenever you are happy or anxious lonely or melancholy-they'll always be the most loyal friends.
And yet the owners should aware of the potential problems such as the pollution. Just as every coin has two sides so does this issue.
It would be a good thing to keep pet dogs as long as their owners cared for and educated them responsibly.
