Everyone has their own duties. They need to obey their own rules. As a student， what should we do？
In my opinion， we need to be polite at school. It’s common that students always say dirty words. It’s very impolite. And the people will feel uncomfortable. So we’re not supposed to do it. To be a polite student， we are expected to help our classmates in need. You can also feel happy for it， too. Second， we’re not expected to talk loudly in public， especially in the libraries， restaurants and so on. It can be a noise for others. Third， I think the most important one is to be honest to our parents at home. If you always tell lies， they won’t believe you at last. Then you may feel lonely and sad.
范文：
As a student， it is very important for us to be a polite person. But what shall we do？
First， we should treat our parents politely. We should answer them immediately when they talk to us. Don’t shout at them when they have different opinions. Share some housework like doing the dishes.
Second， we should greet the teachers， and bow when seeing them in the hallways. Never should a student argue with the teachers. Of course， students should also treat each other politely.
Other people such as the elders should also be treated politely. It is a student’s duty to help them， like sharing seats.
In short， a polite person can make a difference in our society. Let’s start to be polite today！

英语作文不同于汉语作文，我们主要是要按照要求用英语写出准确的句子。为减少失误，应尽量使用简单句，即一个句子一主语一谓语，同时注意but、and等连接词的使用，还要注意主谓一致和固定短语、句型的灵活运用。
