英语说明文范文如下：

In everybody’s eyes, I am a good girl, because I make the good marks in the exams and help my parents to do things. Unlike other students, who will go against their parents, I follow my parents’ words. I don’t think that to do something goes against the adults is the wise choice, but I do want to do something new.

Recently, I want to cut my hair and make the short style. My mother doesnt agree with me, because she thinks a girl should have the long hair. This time, I insist on my idea. Finally, she supports me.

Trying something new makes me feel happy and be myself. The short hair makes me look like a cool boy and I like this style. My friends admire me to have the courage to change my image.

翻译：

在大家眼中，我就是一个好女孩，因为我考试成绩好，还帮助父母做事。不像其他学生，会和父母作对，我很听父母的话。我认为做一些违背大人们的事情是不明智的选择，但我想做一些创新。最近，我想把我的头发剪了，留短发。

我妈妈不同意我的做法，因为她认为一个女孩就应该留长头发。这一次，我坚持我的想法。最后，她支持了我。尝试新事物让我感到预约，做我自己。短发使我看起来像一个很酷的男孩，但是我喜欢这种风格。我的朋友都羡慕我有勇气去改变自己的形象。
