四级b类作文【一】
春天， 万物复苏，小河水哗哗地顺流而下； 活泼机灵的小鸟们在枝头喳喳地纵情歌唱； 小草们神不知鬼不觉地从地下探出了脑袋，大地换上了绿色的新衣； 小野花们争先恐后地展示着自己的美丽； 一棵棵大树好像正在返老还童， 抽出嫩黄色的新芽；。年迈的`凤凰木也紧跟着春天的步伐， 吐出米粒大小的嫩叶， 就像刚出生的婴儿那般娇嫩。
夏天，太阳像一个火炉似地炙烤着地面。凤凰木的叶子早已变成了深绿色，枝条也向四周扩展了许多，变成了一把绿色的大伞。当太阳透过茂密的树叶筛下一束束金光时， 美丽的凤凰花绽开了一张张笑脸，好像给凤凰木披上了红色的霞衣。
秋天，凤凰树的叶子慢慢地变成了金黄色，在微风吹拂下纷纷飘落下来， 给地面铺上了一层厚厚的金色地毯。课间十分钟，我和小伙伴们在凤凰树下尽情地玩耍、嬉闹，甭提有多高兴了。
冬天，刺骨的寒风从耳边呼呼地刮过，古老的凤凰木褪去了繁华，仿佛一个弯着腰、知识渊博的老学者，正在讲述着她一百多年来的沧桑岁月， 并勉励我们克服各种困难、勤奋学习，成为对国家有贡献的人才。
这就是我们百年老校的百年古树---凤凰木。

到中流击水，浪遏飞舟。——题记
青春，是一座桥，一座幼稚单纯通向睿智坚强的桥。恰同学少年，风华正茂，尽是追求，尽是拼搏，让我们与老师、与同学携手走进青春感受这奋进昂扬的美好时光。
师生斗智求真知
阳光泼洒在窗棂，数学老师正在给我们手舞足蹈讲课。“正多边形对称轴是它每一个边的中垂线，条数是它的边数!”这洪亮的声音充满威严，让人觉那仿佛是不容置疑的.真理。可是，一丝思维的火花在脑中闪过：“正方形的两条对角线也是对称轴呀!所有的正偶数边形都有与对角线重叠的对称轴”。老师显然错了!课后，我立即追上他，告诉他我的想法，他迟疑片刻说：“你画图没有，几何画图就明白了!教书几十年，我心中有数!”他的语气坚定自信，又语重心长。一旁的同学说：“老师是大数学家，你一个学生就不要和专家争了。”老师笑了笑，起身想离开。我不甘心，立即用笔画图给他看。老师抬抬眼镜，疑惑地看着图形上的线条——正方形的确有与对角线重合的对称轴!他显得惊讶，紧锁着眉头，手摸下頦，看了良久。终于，他舒展眉毛，对我说：“哎呀，老师还真弄错了……正偶数边形还有与对角线重合的对称轴!”大家会心地笑了。
让我们与老师一起追求知识和真理，携手走进青春!
同窗助威展风彩
雨丝落在操场，可比赛仍在继续。我正与对手们站在800米赛道的起点线上，哨声一响，箭一般冲了出去。加油声在耳畔，不断响起，似松涛!似雷鸣!迎着风，冒着雨，快步向前，对手们一个个从身边闪过，前方的身影越来越少，我暂时领先为第一!400、300……到最后冲刺的200米，加油的人群中传来一个焦急的声音：“来了!来了!右边，快啊!”余光中，右边的确有了黑影，对手几乎与我持平，这最后竞争的关键时刻来了。“快啊!快啊!……加油!加油!……同学助威声越来越烈，似急促的战鼓，冲锋的号角，我迫使自己的每个细胞都与氧气结合，迸发出奇伟的能量，在同学的鼓励声中，我忘情了，没命了，发狠了，超越对手，险胜夺冠!
让我们与同学一起为荣誉和胜利拼搏，携手走进青春!
青春岁月，来匆匆，去匆匆。曾记否!到中流击水，浪遏飞舟。让我们，永远携手走进青春，收获知识，收获成长，收获无悔青春。

Dear all,
I am writing this letter to express my gratitude to my parents for teaching me to be positive and to be strong. “Educating the mind without educating the heart is no education at all.” is the opinion held by Aristotle. It is the experience of our forefathers, however, it is correct even today, including my parenting.
It is widely acknowledged that parenting, which can also be explained as family education, is of great significance in our character forming and manner acquiring. To be more detailed, setting good examples instead of just giving precepts is the greatest achievement of my parents. They not only taught me to think for the best and prepare for the worst; they taught me how. They not only told me the benefits of being strong in mind; they proved it. All those things require huge amount of time and work, but it’s worth it.
Without my parents’ contribution and education, I would never be who I am now. But most importantly, I would never be more gratitude to them than today.
Yours,
XXX

Dear my father and mother,
This letter is my inner feelings. I want to thank both of you for so many years’ care and help.
During my growth, you have made a lot of efforts and love for me. When I make a success, both of you are more excited than me, and support me to do better. Even though I have failed, you always share sorrow with me and encourage me not to give up. Especially, during my preparation for CET-4, the support from you is always everywhere. I have passed the exam successfully.
You love is so unselfish that I am deeply affected, so I will study hard to be a useful person and won’t make you disappointed. Anyway, I would like to express the deep gratitude to you.
With best wishes.
Sincerely yours,
Li Ming

今天，我们在下社团课的时候，还高高兴兴地走在回教室的路上，等我们一进教室，大家都惊呆了：尹老师让我们带的十只小鱼和一只大鱼都了，花花草草也被人破坏了，花瓣都被人揪掉了，仙人掌被人掰断了，桌布也被人画得乱七八糟的，竟然还有的同学丢了铅笔......还有一个最重要的事儿是，了的大鱼的鱼鳞全没了，现场惨不忍睹，大家都非常气愤。想马上找出来是谁干的，一定要好好地教训他一顿。
在此，我想对在我们教室上机器人课的同学们说
1、请你们不要伤害我们的`花花草草和小动物，你们要爱护它们，不要去破坏它们；
2、请尊重我们的劳动成果，未经允许，不要动我们的东西；
3、如果是你们其中的哪位同学折断花，弄的小鱼……希望你们能主动找尹老师承认错误，我们会原谅你的；
4、如果你们以后再随意乱动我们的公物，我们会告诉学校，校长会严厉惩罚你们的，希望你们引以为戒，好自为知！
最后希望你们能用实际行动证明自己！

Dear Mary,
You said in your letter that many of your classmates wore fashionableclothes, but you couldn't afford them so you felt very depressed. There are dif-ferent views on people's clothes. The followings are my ideas:
Firstly, you shouldn't put too much emphasis on physical appearance.
Remember that the most important task for you today is to concentrate on yourstudies. No matter what you wear, you will really look your best when youcome out first in your examinations.
Secondly, you should understand that it is a fine virtue to live in fru-gality. Just as a famous saying goes, Frugality is the mother of virtue.
Since your family can't provide you with enough money to buy fashionableclothes, it is all the more necessary for you to try to lighten the financialburden of your family. And you will find the virtue of frugality benefit youa lot in your future life.
I hope you understand what I mean. Hope you will take a positive attitudetowards life and will be happy again when you read my letter.
Yours,
Anne
