我们小组叫黑马组，一听这名就知道这是一队充满无限能量的黑马，是一个很酷的小组。我们组共有6个人我是二号，下面我来一一介绍我们的小组其他成员吧。
一号是我们的大组长杨书研，她的优点是做事认真。如果你要是有题不会做，她会认真仔细的\'给你讲解，直到你明白后才会让你走，但她也是个急性子，这使我们的小组成员感到很不爽。有一次老师把考试卷子发下来让我们更改错题，我有一道题改完了，给她帮我检查，可她以为我改完了，想快速交卷给我们组加分，二话不说，直奔老师而去，还好我这次全部做对，不然的话就惨了。
三号是我们组的陈雨菲，她得优点是无私奉献，如果组内有谁忘带学习用具，她就算自己不用，也会把自己的学习用具借给对方，她这种无私奉献的精神值得我们学习。可是她也有办事拖拉的毛病。语文老师规定：每天上午和下午在规定时间到达教室学习的小组可加六分，可是我们都上课了，她才到达教室学习，唉……真没办法！
四号是徐莹，如果她高兴的时候，肚子里有好多冷笑话讲给我们组的每个人听，如果她和组内的同学发生矛盾了，她的脾气可就要爆发了，看到谁就想和谁吵！
五号是我们组的杨家乐，他乐于助人，记得上次冯博被高年级的同学无辜的欺负了，杨家乐挺身而出，敢于向老师报告，帮助低年级的同学。
不同的性格组成了我们的黑马组，我们这个小组一定要团结努力，好好学习，考试取得好成绩，给培养我们的老师和家长一份满意的答卷，做一队真正的黑马。

I have a great mother. She cares much about me in my life and study.
In the morning, she gets up early to make breakfast for me. When I was little, she prepared my schoolbag. But now, she tells me to do it by myself. Because she thinks I have been old enough to do it. Besides, she always checks my homework. When I finish my homework, she checks it and points out the mistakes. She is very careful and helps me a lot.
I love my mother.
