为什么要努力学习500字作文【一】
Study is our student's personality.But many students will ask, why we must learn knowledge. Is knowledge so important to us?If we don't need to pass the exam, should we still need the knowledge?
As I am concerned, study is not only a personality of students, but also a personality of all people throughout their lives.People need to learn the knowledge whoever they are.If people don't learn knowledge, there will have no way to do things and become ignorant about world.Can you imagine a world that no people have knowledge?Leaving knowledge,the world would no get progress.If people don't learn knowledge, there will be no people to know how to use the computer ,how to write the news, even how to communicate with others.
So learning knowledge is a very important thing, it consists of our world.
为什么要努力学习500字作文【二】
只能够自认倒霉了！谁叫我平时不好好学习，考试前又不好好复习。上课时和旁边的同学说话，别人在做作业的时候，我却一个人在玩耍，自己的成绩自己知道，一股劲地往下退，直线下降嘛！尤其是数学，我一点也听不懂，上课就像梦游一样，老师上到那儿就算到那儿，听了就忘，简直是一只耳朵进，一只耳朵出。简直不知道自己在做什么。平时做作业还要好，做完就不知道自己在做一些什么，为什么这么做。简直像在做梦一样却不知道一个所以然。大部分时候，我只要一遇到做不出的时候就问同学，美其名曰虚心请教，然而实质上是叫别人说了，自己写写，好像自己当一个书记员，只管抄写。老师看到以后经常跟我耐心谈话，说了一大堆道理，我却全部当了耳旁风。到了期中考试的时候，虽然我提前两天知道，但是我说临时抱佛脚，越抱越别脚。所以，大家在复习的时候，我却照玩不误。期中考试考了一个比较差的成绩那是不能够怪别人的呀！只能够怪自己不用功呀！
也许家长会开完，家长们相互通气，妈妈又会掉下伤心的眼泪，因为我是她的'希望，她的骄傲，她的精神支柱。可是，我就是那么不争气，成绩那么差我想自己真的不应该让他们那么失望，那么伤心，那么落泪。从现在开始，我一定要加倍努力学习，争取以后考试次次都取得好成绩！那么让自己的父母也能够在家长会上抬起头来。
