【正确答案】[范文] Keeping Pets There is no denying that keeping pets is a hotly debated topic today. Some people claim that keeping pets is a good thing. They believe that pets, like cats and dogs, can help relieve the loneliness suffered by senior citizens. They also argue that keeping pets helps mankind understand animals' world and develop positive feelings toward them. Others, however, hold the opposite view. They regard keeping pets as a harmful thing. First, keeping pets is unhealthy. Pets can transmit diseases. Second, the noise and dung of pets are sources of pollution. Last but not least, as many rare birds and animals are kept as pets, they will surely be hunted on a large scale, which means a threat to the balance of the ecosystem. Weighing the arguments of both sides, I am inclined to agree with the latter. Anyway, we can lessen our loneliness and express our love toward animals in other ways. And it is believed that only by placing man and other species on an equal basis can we expect to have a lively and colorful world.

【答案解析】本文属对比分析类议论文。此类作文要求对同种或两种事物进行比较，然后得出结论。“养宠物”属提纲式作文。根据题中所给提示，本文可用三段式的谋篇形式。 第一段：陈述有些人支持养宠物，并阐述养宠物的优势。 第二段：相反，有些人则反对养宠物，并阐释养宠物的弊端。 第三段：陈述个人观点。 [参考译文] 养宠物 不可否认，养宠物是一个热议的话题。一些人认为养宠物是一件好事情。他们认为宠物，比如猫和狗，可以帮助老年人缓解孤独。他们还认为，养宠物有助于人类理解动物的世界并且对它们持友好的态度。 然而，还有一些人持相反的观点。他们认为养宠物是一件有害的事情。首先，养宠物是不健康的。宠物会传播疾病。其次，噪音和宠物粪便是污染的来源。最后，许多珍稀鸟类和动物作为宠物饲养，它们肯定会被大规模捕杀，这意味着对生态系统平衡的威胁。 权衡双方的论点，我倾向于同意后者。无论如何，我们可以通过其他方式减轻孤独、表达我们对动物的爱。相信只有人与其他物种平等相处，我们才会拥有一个充满活力、多姿多彩的世界。
