Перевод текста с английского на русский, очень срочно надо)

Our school is in a small town on the coast and tourism is very important for our community. One of the problems we've been having though is all the litter that gets left on the beaches. It's not all left by tourists. Unfortunately, most gets dumped by people who live in the area and some is washed up by the sea. Anyway, we decided to do something about it, so once a week during the summer we organised ourselves into work parties and cleaned the beaches. Apart from helping the image of the town, it gave us the chance to get plenty of fresh air.

In citizenship classes. we visit elderly people in the community, who have difficulty in doing things for themselves, and help them. This means doing things like going to the shops and helping out in the house and garden. Sometimes, all we do is just have a chat with them. Sometimes we can find out something about life from them, because they've lived through a lot and have plenty of experience. I think it's important for different generations to look out for each other.

It's very beautiful here in the mountains and we get a lot of visitors, but beneath all the beauty it is quite a wild and dangerous place. I should know because I'm a volunteer with the local mountain rescue service. Naturally, we receive instruction in first-aid and how to use maps and compasses. I've even been in a helicopter. Last summer, I helped find a walker who had fallen and broken his leg. If we hadn't got to him. he would have died.
