Many people have pets. Other people don’t. In your opinion, is it a good idea to have a pet, such as a bird, dog, or cat? Why or why not? Use specific reasons and examples to support your answer.
说到宠物话题的利与弊自然大家都能例举出很多例如： companionship and reduces stress or hygiene problem and expense。如果你更倾向于好处时，我们通常需要一个让步段来支持不好的观点：
It seems reasonable that some people dislike a pet in the company of them in the daily life. People who do not raise a pet at home may perceive it is less hygienic and is more likely to be infected with parasites. If you have a puppy, its hair might pass microbes that could bring about contagious diseases to our human beings. Moreover, buying the pet food and supplies can be pricy as well. This means your regular disposable income must subtract the amount of expenditure on your pet.
