Recently we have had a heated discussion on whether people should keep pets in cities.One possible version:Dear editor,Recently we have had a heated discussion on whether people should keep pets in cities. Some students think it is a good idea to keep pets, because pets can give company to many old people who live alone at home. Besides, getting along well with animals will make our life more interesting. On the contrary, the other students who are against the idea believe if too many people keep pets, it will do harm to the environment. What’s worse, pets may make too much noise and even attack people.I like animals, so I don’t think it’s bad to keep pets, but we must take some measures to prevent them from polluting our environment.。
