As a Student (改：As a student) , it is necessary to have a good behavior. And I will tell you something about being a civilized student.（段评：作为说明文的开头,你明确点出了成为文明学生的必要性,很好地引出了主题！但有两个小问题可以改进: 1. 语法错误:第一句中的“As a Student”应改为“As a student”,这里的student不是专有名词,不需要大写。 2. 表达优化:“And I will tell you something about being a civilized student”可以更自然,改为“I'd like to share some thoughts on being a civilized student”会更符合说明文的正式语气。修改版：As a student,it is necessary to have good behavior. I'd like to share some thoughts on being a civilized student.）

There is no doubt that being civilized has many meanings. First of all, it can improve ourselves and show our good characteristics. Secondly, behaving politely can bring peace and happiness to others, which is good for our relationship. Moreover, a civilized person could also make the society much better. In a word, we students should learn to be civilized.（段评：你用了First of all、Secondly、Moreover这些连接词,让段落的逻辑很清晰,值得表扬！不过有一处表达可以更准确: 1. 词不达意:“show our good characteristics”中的“characteristics”更偏向“性格特点”,用“qualities”(品质)来表达“良好品质”会更贴切。 2. 语法优化:“a civilized person could also make the society much better”中的“could”可以改为“can”,因为这里是陈述客观事实,用一般现在时更合适。修改版：There is no doubt that being civilized has many meanings.

Here are some suggestions on how to do this. As the saying goes, 'Actions speak louder than words'. We ought to take action instead of just saying. Caring about others is also a good way which helps us become more civilized. It is important to behave politely in public. Besides, paying more attention to our manners also matters our politeness (改：matters for our politeness) .（段评：你给出的建议很实用,还引用了谚语,很棒！但有两个地方可以优化: 1. 语法错误:“which helps us become more civilized”中的“helps”应改为“help”,因为先行词是“a good way”,单数名词作主语,谓语动词用第三人称单数。 2. 搭配不当:“matters our politeness”应改为“matters for our politeness”,“matter for”是正确的搭配,表示“对……重要”。修改版：Here are some suggestions on how to do this.

These are all my opinions about being a civilized student. I hope this article will help you become more polite after you reading it (改：after you read it) .（段评：结尾总结了全文观点,还表达了对读者的期望,不错！但有一处语法错误: 1. 语法错误:“after you reading it”应改为“after you read it”,“after”引导时间状语从句,从句要用完整的主谓结构。修改版：These are all my opinions about being a civilized student. I hope this article will help you become more polite after you read it.）
