纵观历史，大凡获得成功的人，都有一些良好行为长期坚持，养成习惯，形成自然。鲁迅先生从小就养成不迟到的习惯，他要求自己抓紧时间，时时刻刻地叮嘱自己凡事都要早做，这样长时间地坚持下去，就养成了习惯。这位以“小跑走完一生”的作家，在中国以至世界文学史上留下了辉煌的业绩。可见，行为习惯对一个人各方面的素质起了决定性的作用，对我们小学生来讲，尤为重要。

就拿我们密切相关的学习来说吧。我们经常看到这样的现象，有些同学平时不刻苦、不用功，作业总是马虎潦草，没有养成踏实认真的学习习惯，成绩总是不好;我们也看到，有些同学双休日只顾玩，把作业压到星期日晚上才去做，开了夜车还做不好。其实，这完全是学习习惯和方法的问题。大家都知道，一个好的、科学的学习习惯和方法，能使我们既学得有效率，又学得轻松自在。而如果你不能养成好的习惯，上课不注意听讲，不踊跃发言，不钻研难题，这样不但不能提高效率，而且对你的身心发展也会造成不利的影响。因此，我们在学习时，最重要的是养成一个良好的学习习惯。它会使你终生受益。

昨日的习惯，已经造就了今日的我们;今日的习惯决定明天的我们。让我们从现在做起，从今天做起，养成良好的行为习惯，做一个优秀的小学生，共同创造辉煌的未来!

谢谢大家!

i always feel tired after eight classes a day, so my dream school starts at 8:30 a.m. and ends at 3:30 p.m. there are three lessons in the morning and two in the afternoon. we can choose our favorite lessons to learn. we can spend more time doing some outside reading. the students do after-school activities for one and a half hours every day. we needn’t do a lot of homework. we are all happy to stay at school.

besides that, my dream school looks like a big garden. there are many kinds of flowers around the modern buildings. sweet perfumes are diffused all around. if i want to have a rest, i can lie on the grass, listen to music by the lake or look out at the flowers from the classroom windows.

the teachers here are kind and helpful. they are not only our teachers but also our good friends. the students are polite and friendly. we all know how to keep our school clean and tidy. there is no litter around the campus.

i love my dream school. we will grow up to be happier there.

老师们，同学们：

中国的环境污染已非常严重，如果我们再不保护环境，我们的家园将陷入危机-土地会沙漠化，pm2.5入侵全球……这些我们肯定都不愿发生，但事实是：土地有一半沙漠化，pm2.5已入侵北京。水污染也非常破坏环境，打个比方说吧：日本以前是靠打鱼为生，如果水被污染了那些人会怎样?但不幸的是，那里的水真的被污染了那些吃了鱼的人都得了一种怪病：水俣病，这是一种在当时治不好的病，很多人被无情的病魔夺走了生命，也有很多人在生死线上与病魔做着最后的斗争，但是很不幸，做着斗争的人有很大一部分在斗争中丧失了战斗力，与人世告别了。

还有树木，它们也是环保的一部分，它们整天吸收二氧化碳，呼出的却是人类需要的氧气，但是因为我们人类的过度开采，很多树木都倒下了，而讽刺的是：我们过度开发树木用来造纸，却在纸上写下了：保护环，不过度开采树木的假象，而那些伐木工依然日夜不停的砍伐，把我们的家园搞得千疮百孔。我们的家园多么可爱呀，像是一颗蓝色的明珠在浩瀚的宇宙中闪烁，但是，如果全球的土地都被沙漠化，世界将会怎样?如果pm2.5侵入全球，那又会怎样?如果世界上的水都被污染了，那会怎样?如果地球上的树木全都被砍光了，那又是怎样?如果地球被毁灭了，那人类又会怎样?

我们这个地球太可爱了，又太脆弱了。这是宇航员飞上太空目睹地球时的感叹。为了保护我们赖以生存的家园，请我做起，从他人作起一起来保卫我们共同的地球妈妈吧!

各位花草树木、水沟河流们：

大家好!

我相信大家对我不陌生吧，我就是百年前聚会时的小河呀!那时的`我呀，年轻气盛，无人能比，就连智多识广的大海老爷爷也比不过我!

可是现在，大家肯定认不出我了吧?我是不是很像刚挖开的黑水沟小弟弟呀?大家看看我吧!现已患了“哮喘”，说话大喘气，上次呀，我还差点得了“癌症”，而且我现在还染上了“河皮癣”!

再看看我的衣服吧!有的东西在我身上待了好几年了，看一看啊，他们人类把我点的“五彩缤纷”：这是七月前一个老婆婆的塑料袋;这是一年前一个小孩“送”给我的可口可乐;这是三年前一个农民随手扔下的坏猪肉，现在都被泡涨了……看一看，还哪有一百年前那矫健、清澈、可爱的身影啊!

要知道，以前人们在我身上嬉水，在我肚中游泳……七年前的一天，在离岸不远的地方开了一家油漆场，夜晚，总在些人偷偷摸摸的挖着“地道”。有一天那地道通到了我身边，并且接上了一根粗管子，我好奇的朝里看了一下，突然一阵恶臭扑鼻而来，我立即缩头，这时，一阵黑水一下涌出……从那以后，人们不再嬉水、游泳，久而抱怨、污染起我来，要知道害我的人是你们呀!

啊，我真希望人们改过自新，不再污染、破坏我们，让我们永远清澈!

谢谢大家，我的演讲完毕!
