keeping pets

i'm written to tell you about the recent discussion that we 've whether people should keep pets at home in cities。the oppions are divided into two parts 。some students believe that pets can bring happiness to lonely people which always company with the old and young person,so that these people don't feel lonely any more。Besides ,we can learn how to stay with animals and strongthen our abilities。Most of all ,we all konw that the pets are extremly intresting and cute 。on the country ,some students support the other idea that keep a pet is costly。what is worse,many adventages ,for instance,pullute the environment,bring too much noise,even attract people。it also give us many troubles and add our burdons。so they are against keeping pets。As for me,i prefer keeping pets。coz i love animals and wanna be close to them 。Furthermore,we have the obligations to create a warm and comfortable home to the animals 。we also need to avoid the bad influnces when we keep pets。
