As a middle student (改：middle school student) , every person of us (改：each of us) should be helpful and honest. To be a good student with some good manners, here are some suggestions for you.（段评：这段作为开头,点明了礼貌的重要性并引出建议,主题明确！但存在两个问题: 1. 运行句(连写句):第一句中两个独立句子用逗号连接,如"Good manners are very important,it can show...",应改为复合句。 2. 词汇使用:"middle student"是中式表达,应改为"middle school student"；"every person of us"可简化为"each of us"更自然。修改版：Good manners are very important because they can show if you are friendly or civilized. As a middle school student,each of us should be helpful and honest. To be a good student with good manners,here are some suggestions for you.）

First, help people who have some problems. You should try to help them with their problems and tell them the things about how to solve these problems by using friendly and polite words. Second, you should always be honest. Even if you have made something wrong (改：have done something wrong) , you should also be honest. Also, if you friends (改：your friends) tell lies to their teachers or parents, you should ask them not to do these things and be honest to other people. Third, you should be kind to others, too. You should talk with other people friendly (改：talk to others in a friendly way) . In this way, you will make many friends and improve yourself.（段评：这段列出了三个具体建议,内容充实！但存在以下问题: 1. 词汇重复:多次使用"problems"和"honest",可适当替换同义词如"difficulties"、"truthful"。 2. 句式单调:多为简单句,可增加复合句如条件句、定语从句使表达更丰富。 3. 表达冗余:"have made something wrong"可简化为"have done something wrong"更简洁。修改版：First,help people who are facing difficulties.
