写作思路：可以将班级竞选班长的过程以及发生的事情进行详细地描述，中心要明确，语言要通顺，避免语法使用错误等等。
正文：
"Ding Lingling..." the class bell rang, and the students rushed into the classroom like a swarm of bees. They immediately sat down and waited for the teacher to come in. All of a sudden, Mr. Gao walked into the classroom with a big stride. The classroom is not as noisy as before. On the contrary, it is so quiet that you can hear a piece of paper floating to the ground. Because we are running for monitor today, we all want to listen to the speeches of monitor candidates.
“叮铃铃……”上课铃声响了，同学们都一窝蜂似的冲进了教室，马上坐好，等待着老师进了进来。突然，高老师大步流星地走进了教室。教室也不像以前吵闹了，反而安静得连一张纸飘到地上都能听得见。因为今天要竞选班长，我们都想听一听班长候选人的演讲词。
My best friend Guo Haoyu was the first one to appear on the stage. He used to be a deputy monitor. He walked slowly onto the platform with a dignified face, frowning and staring at every word of the speech, hoping to eat them. As he read, tears came down one by one, and a few words came out of his mouth: "Xiao Ming, I used to bully you. I'm sorry, please forgive me!"
第一位出场的是我的死党郭昊宇，他曾经当过副班长，他慢吞吞地走上讲台，面色凝重，皱起眉头，目不转睛地盯着演讲稿的每一个字，恨不得把它们吃了。他读着读着，一颗颗泪珠流了下来，嘴里还吐出几个字来：“小明我以前老是欺负你，对不起，请原谅我！”
I don't know which student started to say: "Guo Haoyu, don't cry." Students also said: "Guo Haoyu, don't cry." Guo Haoyu dried his tears and stopped crying. When he finished reading his speech, there were bursts of applause. Obviously, everyone was moved by his initiative to admit his mistake.
不知道哪位同学起头说：“郭昊宇，别哭了。”同学们也说：“郭昊宇，别哭了。”郭昊宇才把眼泪擦干，不哭了。他把演讲稿读完，迎接他的是一阵阵热烈的掌声。显然大家都被他主动认错的精神所感动了。
Then the two contestants came on stage in turn, but most of the contents of the speech were the same, and did not mention too much interest of the students. The fourth is Shi Peiliang, the most famous handsome man in our class. He looked at the speech in his hand and began to read it, but it was silent after a while. Some students began to laugh secretly. Gradually, they began to laugh.
接着又是两位选手依次上场，但演讲的内容大部分都一样，并没有提起同学们太多的兴趣。第四个是我们班大名鼎鼎的大帅哥——石培良。他看着手中的演讲稿开始读了，不过一会儿就没声了。有的同学开始偷偷笑起来，渐渐地，便大笑起来。
"In order to run for the monitor, Shi Peiliang came to the school with his illness. Don't laugh," Mr. Gao said All of a sudden, there was no sound under the platform, as if he was inspired, his language was fluent, and everyone cheered for him.
高老师大声说：“为了竞选班长，石培良同学忍病来到学校，大家不要笑。”顿时，讲台下面没了声，仿佛受到了鼓舞，他的语言流畅了许多，大家都为他欢呼起来。
At the end of the election campaign, I gave my precious vote to Guo Haoyu, who successfully became the monitor of our class 4 (3).
竞选结束了，我把宝贵的一票投给了郭昊宇，他也顺利地成为了我们四（3）班的班长。
Election monitor speech
尊敬的老师、亲爱的同学们：
Dear teachers, dear students:
大家好！
hello everyone！
今天，我能站在讲台上参加我们班的班长竞选。我感到非常自豪，也非常紧张。
Today, I can stand on the platform to participate in our class leader election campaign. I feel very proud and very nervous.
其实，当班长是我梦寐以求的梦想。因为我平时不爱讲话，而且也比较胆小。特别是在课堂上，平时不大举手，而且会大声音也比较小。
In fact, when the monitor is my dream dream. Because I usually do not love speech, but also more timid. Especially in the classroom, usually do not raise their hands, and will be a large voice is relatively small.
假如我当上了班长。我会变得大胆些，上课积极举手。
If I were on the monitor. I will be bold, active in class.
假如我当上了班长。如果同学遇到不会做的题目，我一定会详细的告诉他怎么做。我还会多组织一些活动：跳绳比赛、书法比赛、跑步比赛……我还会再叫一些同学捐一些书放在角落的书柜里，这样，同学们就可以提高学习成绩。我还会将一些成绩好的同学教一教一些稍微不理想的同学，到时候他们的成绩也会提高了。
If I were on the monitor. If the students will not do the subject, I will tell him in detail how to do. I will also organize some activities: rope skipping competition, calligraphy competition, running competition...... I'll ask some students to donate some books in the corner of the bookcase, in this way, students can improve academic performance. I will also some good students to teach some students a little less ideal, then their results will be improved.
如果我当上了班长。我一定会把以前的缺点改掉，而且还会更加努力学习，争取成绩名列前茅。
If I were on the monitor. I will give up the shortcomings of the past, but also more efforts to learn, for the best results.
请老师、同学们支持我，请投我一票，谢谢大家！

今天，我们班竞选班长了。`我成为了新的班长。我很高兴，不过我现在仍然很紧张。竞选开始的时候，我好紧张，我都可以听到我的心怦怦跳了。我努力了很长一段时间才平静下来。然后我才走向讲台开始我已经准备好的演讲。在演讲的时候，我觉得我的大脑一片空白。在竞选之前，我对这一职位是很有信心，但当我站在讲台上时还是很紧张。幸好提前准备了；否则，我肯定很难堪。不过结果却是我想要的。这是一件值得开心的事。
