We have had a heated discussion about keeping pets on our English Talking Show recently.Some are in favour of keeping pets,while others are against it.
The supporters think keeping pets shows that they can live in harmony with nature,in which people can develop their inner minds.(高分句型一)For old people,keeping pets can bring them joy,thus driving away their loneness when their family are not beside them.(高分句型二)
However,those who are against it argue that it is a waste of time,money and energy.Besides,pets often make our living environment dirty and smelly.More importantly,pets may sometimes attack people.
Personally,I think it's one's freedom to decide whether to keep pets or not.But pets must be kept on condition that they don't cause trouble to others.(高分句型三)
