阅读下面的短文，然后按照要求写一篇150词左右的英语短文。

We spend hours, days and years of our lives in education. But how perfect do you think your school is? Imagine you could decide your ideal school. What would it be like? What would you be doing? We wanted to find out what teenagers around the world thought. Here is what they said.

Sonia from Italy: I’d like a room where we can go and relax and play computer games and chat with friends. Some older pupils in the school have this but I think there should be a place for everyone to go when they want to switch off from the lessons.

Richard form USA: I think it would be great to have a day off every week, as well as the weekend. If that day was a Friday or a Monday, we would have a long weekend every week. I’m sure we could learn just as much in fewer hours.

David from UK: The school dinners are absolutely disgusting. There is a little shop called a “tuck shop” which we can go to in our breaks but it just sells rubbish. I’d like to be able to buy fruit and healthy snacks.

Hannah from Australia: My school environment is great – especially the sports facilities. We’ve got a swimming pool and tennis court. It’s teachers I’d change. I think they should give us more freedom and choice about how we study and what we study. I also think it’s ridiculous that we have to wear a school uniform.

Sam form Mexico: I’d like clean toilets and showers, a big library, big lockers and a restaurant. Not much to ask for.
