Nowadays, pets become so close and friendly to our human-beings that more and more people enjoy keeping them. Pets can bring them a lot of joys and happiness, because playing with pets is a good way to communicate with the nature. Besides, pets can comfort old people who live alone. With the companion of pets, they won’t feel lonely. Nevertheless, I’m not interested in keeping pets at all. For one thing, keeping pets is bad for environmental protection, since pets usually make a lot of noise and contaminate the roads. For another, the virus carried by pets may cause fatal disease. What’s more, sometimes pets may attack people when they are unhappy. Consequently, we had better not keep too many pets, so as to ensure our health and security. Besides, those pet lovers must take some effective measures to prevent their pets from hurting people and polluting our environment. ){ u#

如今，宠物跟人类的关系都很亲密和友好，越来越多的人也喜欢养宠物。宠物可以给他们带来很多快乐和幸福，因为和宠物玩耍是一种与大自然交流的好方法。此外，宠物可以安慰独居老人。有宠物的陪伴，他们不会感到孤独。然而，我对养宠物一点也不感兴趣。一方面，养宠物不利于环境保护，因为宠物通常会制造很多噪音，污染道路。另一方面，宠物携带的病毒可能会导致致命的疾病。更重要的是，有时宠物心情不好的时候可能会攻击人类。因此，我们最好不要养太多的宠物，确保我们的健康和安全。此外，那些宠物爱好者必须采取一些有效的措施来防止他们的宠物伤害人类和污染我们的环境。
