Now it is not allowed to set off firecrackers in big cities on festivals. Some people are against it. But I am for the idea.

some people think setting off firecrackers is a traditional way to celebrate important festivals, especially the Spring Festival. It can show people's happiness, their feelings and the festive mood. And people can enjoy the beautiful scenery of fireworks.

On the other, hand, as we all know, setting off firecrackers may cause a lot of trouble. It may bring big fires and air pollution. And it will do harm to people's eyes and hearing. If firecrackers are not set off correctly they can injure or disable people or even cause death' This will bring great sorrow to the family.

From these we can see there are more disadvantages, So I approve of not setting off firecrackers, and we should seek other ways to show our happiness.

现在大城市在节假日里不允许燃放鞭炮。有些人反对这么做，但是我赞成。

一些人认为燃放鞭炮是庆祝重要节日的传统方式，尤其是春节。它可以展示人们快乐、热情的节日气氛。人们也可以欣赏美丽的烟火。

另一方面，众所周知，燃放鞭炮会给人们带来很多麻烦。它会引起大火以及空气污染;它会损坏人们的视力和听觉;如果鞭炮燃放不正确，它全使人们受伤或致残，甚至升起死亡。这会给家庭带来很大的痛苦。

从这些我们可以看到燃放鞭炮弊大于利，所以我赞同不放鞭炮。我们应该寻找其他方式来表达我们的喜悦之情。
