如何预防青少年犯罪的作文500字【一】
星期五，我和爸爸妈妈一起看了一个法制节目，这使我受到了很大的启发。节目中的很多很多的青少年，他们犯了法。他们现在被关入大墙之中，后悔莫及。
当他们见到自己的亲人后，一直在听他们的教育。当然现在听已经太晚了，如果当时听一下他们的劝告，也就不会落在这个泥潭之中。他们没有一个人不关心家里的，没有一个人不后悔的，没有一个人不想好好改造后到大墙外面去，获得自由的。如果再给他们最后一次机会，他们一定不会再犯罪的。其实，在我们身边也有很多的例子，比如：一个同学把另一个同学的橡皮弄没了，那个同学肯定会去找他算帐，就难免打架。在玩的时候，有人只是开个玩笑，拿一下别人的东西，而那个人以为他是故意的，就上去打架。现在很多少年罪犯都有一个规律是：辍学——流失——染上恶习——犯罪。往往也有很多人都不想***人，而是在自卫时都误***了他人。
很多青少年犯罪的原因：他们没有把精力放在学习上，而是在社会上闲逛或去上网吧结识一些坏人。我们平时要把精力放在学习上，不但要把数学、语文学好，更要把思想品德学好，要从现在开始，从我开始，和人相处要团结友爱，相敬如宾，做到宽宏大量，不要为一点小事而斤斤计较，要有正确的思想观，不但要德、智、体全面发展，更要做一个有很好心理素质的新新人才，心理的健康，能使青少年犯罪降低到零。
让我们都重视起来吧，杜绝犯罪，特别是青少年犯罪！争做一个优秀的少先队员。
