Taking away a city's rubbish is a big job．Every day tracks come into a city to collect it．Most rubbish is made up of things we can't eat or use．If we kept these things we would soon have a mountain of rubbish．
In some cities the rubbish is collected and taken outside of city to a dump．Often the city dump is placed where the ground is low or there is a big hole．The kitchen rubbish is broken into small pieces and sent into the sewagesystem．The sewage system takes away the used water from toilets，bathtubs and other places．
To keep mice and flies away，some earth is used to cover the newly dumped rubbish．Later，grass may be planted on the rubbish﹣filled land．Finally，a house or a school may be built there，and then you'd never know that this had once been an old rubbish dump．
In other cities the rubbish is burnt in special places．The fire burns everything but the
metal．Sometimes the metal can be used again in factories where things are made of metal．The food parts of rubbish are put in special piles where they slowly change into something called humus，which looks like black earth．It is rich with the kinds of things that feed plants and help make them grow．

Now，I'm studying in the US．I find there are some differences between schools in the US and in Vietnam．
One big difference is the clothes students wear at school and how they look．In my country，all the students should wear uniforms when they go to school．Boys aren't allowed to have long hair．Girls aren't allowed to have long or colored nails（指甲）．
Another difference is about the rules for parents．In Vietnam，when we begin a new school year，our parents have to go to a meeting in our class．If they don't go to that meeting，their children won't have a grade or a report card from school．However，in the US，there aren't such strict rules above．
In Vietnam，a class is only 45minutes and we have only five classes each weekday．When the bell rings，the students just sit in their own classroom．They can't move to a different one，but students can in the US．In Vietnam，students can't go to work because they can't find a job if they're
under18．But in the US，many students work after school．This helps them make money．More importantly，this helps them become more independent．They're able to do things by themselves in their own way，withoutasking other people for help．
