（单词翻译）

　　Dear Editor,I live in Paris,France.In my country there is a famous site,called the Chauvet Caves.I am very worried about it because some of the cave paintings have been destroyed by air pollution.No,the pollution does not come from cars or factories,but from human begings.
Thousands of tourists visit the caves every year.The carbon1 dioxide2 from their breath3 is damaging the paintings.I think one way to solve the problem is to put glass walls in front of the paintings.Second,the number ofvisitors should be limited.And we should build a website where people can look at the pictures and paintings.
Yours sincerely,Sophie
