People say that students don't need to wear uniforms at school . Do you agree or not ? write an essay from 130 -150 words giving your opinion about this .
Câu trả lời của bạn
Đây chỉ là 1 vài ý cơ bản làm dẫn chứng, bạn tham khảo nhé :
In my opinion, students need to wear uniforms at school. School uniforms provide stability. It seems to be fair that all students get dressed in the same clothes
- Uniforms avoid jokes being made about different clothes. Students get bullied because of what they are wearing, uniforms will stop that
- They will pay more attention in class because they don't have to worry about how they look. Instead, they may spend that time thinking about what they have learnt and what they will study
- If students could be allowed to wear casual clothes, some strangers could kidnap a child or something in the school
- Moreover, the uniforms represent your school. When you are wearing your uniform, it makes you proud of your school
