这是某学校通过校长意见箱收集到的一学生的意见和建议。请阅读下文,根据所提的信息,完成下列表格。

Zhang Hongying,girl, 15

I want to make our lunch time longer. At the moment,lunch time is short.Most of my classmates would like to do their homework during this time. But if they don’t get a good rest, they won’t have enough energy for the afternoon. So 1 would like to have more time and have time to take a nap(午睡)after lunch. That way, we’ll learn better in the afternoon.

Zhao Pengran, girl, 15

I would like to have more chances to talk in English. Now, the English classes are not enough for us to practice spoken English. I think we’d better have one morning a week at least to have spoken English lessons in order to improve our English.

Zhou Jiancheng, boy, 15

My idea would be to have more fashionable school uniforms. If I were the headmaster, I would ask the students to design the uniforms themselves. We could have a contest among student designers. Then, we could ask others to choose their favorites. This way, we’ll be able to wear what we like best. How nice it would be for us young people!
