There are many adjectives to describe Class 1A, such as clever, helpful and so on. But I think the most suitable adjectives are active, humorous and polite.
Class 1A is active. Students always participate in the lesson. They raise their hands to answer questions even though they don’t really know if their answers are right. They ask questions if they don’t understand.
Class 1A is humorous. Students like to tell jokes to each other. When you enter Class 1A, you will hear a lot of laughter. You will see students laughing. Everyone’s face has a big smile on it.
Class 1A is polite because they respect the others. They pay full attention to the speaker. They won’t chat while others are talking. They will keep quiet. They won’t say anything which hurts people.
I think Class 1A is a wonderful class. Students in Class 1A are active, humorous and polite. I am really glad that I can be a member of Class 1A. What an awesome class, thanks God!
