Reading1 A letter

Q1：Why did Sophie write the letter？ 

Q2：Can you guess what the editor reply？

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 beings.

Thousands of tourists visit the caves every year. And we should build a website where people can look at the pictures and paintings

Yours sincerely,

Sophie
