近日，山东省华栋中学举行了一次日记大赛，刚刚升入初中七年级（1）班的小雷写的《融入新集体，享受学习》获得了一等奖。下面是小雷这篇日记的部分内容。

升入初中后，一片新的学习天地展现在我面前。新的班级就像一道美丽的彩虹，作为班级的一分子，该怎样为班级增色呢？我决心提高自己的学习成绩。但是学习的道路并不是一帆风顺的，我感觉再沿用小学的一套学习方法已经不适应了，老师要求我们学会做学习的管理者，班里的学习状元也介绍了他的学习方法，我和我的同桌却感觉并不奏效。就在我灰心丧气的时候，前不久发生的一件事改变了我。负责奥林匹克比赛的老师给我们留了的一道思考题作业，我用了近一周的时间，反复琢磨，还是做不出来，决定放弃。这时妈妈对我说：“你不要遇到难题就退缩，学习是一种快乐，不是一种负担。”我听了妈妈的教导，便安下心，重新做了起来，最后终于做出了，而且经检查结果正确。我激动地跳了起来，整个身体完全被一种喜悦和激动的心情所占据了。
