我想做一名宇航员500字作文【一】
自从我上了小学，我们班的班长换了好几位。可是我从来没当过班长。
记得还是上一年级的时候，邻居萌萌当了他们班的班长，妈妈知道后对我说：“你瞧人家萌萌就是比你有出息，刚上一年级就当上了班长。你呢？连语文小组长都不是，真是没出息，等呢长大了能干什么呀？”我想我一定要好好学习，天天向上，遵守纪律，当一回班长。可是我天生胆小，不敢当着大家的面说话，就算我学习成绩很好，但也没能当上班长。就因为这，妈妈经常说我没出息。我心里挺难受的。没当班长就没出息吗？不管我知道自己的缺点――胆小不敢说话。我一定要改掉这坏毛病，练习大胆说话，争取有一天当上班长。
如果我能当一天班长。我要干三件事。第一，我要把这消息马上告诉妈妈，让她说我有出息。第二，我要组织一次全班讨论会，让平时不敢说话的同学当回辩手。第三，我要宣布今后每人都当一天班长，让平时没当过班长的同学都过一下班长的瘾。
我盼望着早一点当班长。
