在今年的三月十三日，我们班的科学老师对我们说："下周，我们将进行科学演讲。"听完老师的布置，我们各个愁眉苦脸，生怕自己演讲。老师说："我点到的是——十......"我瑟瑟发抖，"三!"哦，不!点到的是我!老师对我说："可以做一个小实验，还可以放PPT，或者......"

On March 13 this year, the science teacher of our class said to us, "next week, we will give a science speech." After listening to the teacher's arrangement, we all frowned for fear of giving a speech. The teacher said, "what I ordered was ten..." I shivered, "three!" Oh, no! It's me! The teacher said to me, "you can do a small experiment, put PPT, or..."

回到家中，我轻声对妈妈说："妈妈，下周三是我的科学演讲。"妈妈问："你为什么排在第一个?""因为今天是三月十三日。"我答道。我们演讲的题目是"火山爆发"。在我写作业的时间内，妈妈帮我打完了这篇稿子，我为有这样支持我的妈妈感到无比自豪。但是当我看见稿子的第一时间就惊呆了。啊?怎么这么长!我心里非常不情愿，但想起妈妈曾经说过："还记得学游泳时吗?当你感觉在水中要死了的时候，只要你再挣扎一会儿，探出头来，你就会活下来!"我鼓起勇气，果然，像妈妈所说，事情并没有那么难，不一会儿，第一段和第二段就背完了，第三段(最后一段)最难背，主要是得按化学方式讲讲为什么会爆发出来，为什么用了这些道具，才会产生化学反应呢。呀!终于，花了整整二十多分钟才会完整的、有感情的背诵下来。

Back home, I whispered to my mother, "Mom, next Wednesday is my science speech." Mother asked, "Why are you first?"" Because today is March 13th. " I replied. The topic of our speech is "volcanic eruption". During my homework, my mother helped me finish typing this manuscript. I am very proud of my mother who supports me. But when I saw the manusc

ript, I was stunned at the first time. Ah? Why so long! I was very reluctant, but I remembered my mother once said, "do you remember learning to swim? When you feel like you're dying in the water, as long as you struggle a little longer and stick your head out, you'll survive! " I summoned up my courage. Sure enough, as my mother said, things were not so difficult. After a while, I finished reciting the first and second paragraphs, and the third paragraph (the last paragraph) was the most difficult to recite, mainly because I had to talk about why it broke out in a chemical way and why the chemical reaction would occur only after using these props. Ah! Finally, it took more than 20 minutes to recite it completely and emotionally.

最后，开始模拟过关了，我的道具很整齐，背的声音很洪亮。顺利通过!请同学们期待我明天的展示吧!

Finally, I began to pass the simulation. My props were very neat and the sound of my back was very loud. Smooth passage! Please look forward to my show tomorrow!
