Uniform
You should say:
Why do people wear uniform?
Have you ever worn a uniform?
What role does uniform play in a person’s life?

We all have seen people wearing uniform. People of different professions wear uniforms in order to distinguish them from other people and to show unity. You can easily observe that different organizations have different uniforms. I personally like the uniform of lawyers. Lawyers wear a black coat in my country which is quite good. Apart from lawyers there are also other people who wear uniforms. The most obvious ones are army men, doctors, students, police men and people of other law enforcement agencies.

我们都见过穿制服的人。不同职业的人穿制服是为了区别于其他人，显示团结。你可以很容易地观察到不同的组织有不同的制服。我个人喜欢律师的制服。在我的国家律师穿一件黑色的外套，这很好。除了律师之外，还有其他穿制服的人。最明显的是军人、医生、学生、警察和其他执法机构的人员。

I used to wear a uniform when I was in my school. I used to wear a white shirt and black pants. I was totally not cool with it. I always thought that my school should have allowed all the students in my school to wear their own clothes. I never felt good after wearing the uniform and I wanted to just take it off. But now that I am an adult I realize how wise it was of the school to make us wear these clothes. Wearing a uniform just saves us from the effort to try so hard to choose the clothes. Now I contemplate the idea behind making the students where the uniform. There are some rich and poor people in a school, so the schools introduce a uniform to promote equality and brotherhood amongst them. Uniform plays a vital role in the life of a person. It promotes unity, discipline and integrity. I can easily say that uniform has played a very imperative role in my life.

我在学校的时候经常穿制服。我过去常穿白衬衫和黑裤子。我对此完全不以为然。我一直认为我的学校应该允许所有的学生穿自己的衣服。穿上制服后我感觉很不舒服，我想把它脱掉。但现在我是成年人了，我意识到学校让我们穿这些衣服是多么明智。穿制服只会让我们省下挑选衣服的力气。现在我在思考让学生穿制服背后的想法。学校里有一些富人和穷人，所以学校引入了一套制服来促进他们之间的平等和兄弟情谊。制服在一个人的生活中起着至关重要的作用。它促进团结、纪律和正直。我可以很容易地说，制服在我的生活中扮演了一个非常重要的角色。
