初中英语演讲稿篇1

女士们，先生们：

下午好!我的演讲题目是沙尘暴。

沙尘暴是我国北方地区春季日益频繁发生的一种恶劣天气。虽然我才13岁，但也经历过多次了。

我想大家对上月发生的沙尘暴记忆犹新，它席卷了11个省，给我国造成了很大的`损失。

正如您从电视上看到的，沙尘暴所到之处，狂风卷着黄沙和尘土肆劣横行，有时候一些大树都被从中间吹倒了。鸟儿失去他们的家园，孩子们也找不到回家的路，就像到了世界末日。

当沙尘暴发生时，我们的教室也充满了沙尘。可怜的老师，尽管已饱受粉笔灰之苦，现在又不得不待在灰尘中。可怜的同学们，他们告诉我简直都要窒息了!

我们热爱美丽的春天，我们珍爱明媚的阳光。但是沙尘暴给这些蒙上了阴影，我们知道，沙尘暴是大自然母亲对我们破坏生态劣行的惩罚。要重新看到蔚蓝的天空和明媚的春光，我们必须绿化山川，保护环境。如果我们现在就开始，还不晚。

虽然这是一项艰巨的任务，但是我们必须勇敢地面对，因为这是一场我们必须获胜的战斗!
