If you were working for the UN, which job would like to have using your English abilities? Why?

I would like to work as a teacher. UNESCO provides teaching materials and offers health education so that all childeren in the world can recive an education. In addition, UNESCO conducts education training for local techers on developing countries. It is very important not only education for children, but also training for teachers. I think that children would increase their opportunity to recive an education if the namber of teachers increase. So I would like to teach knowledge of education as a teacher.
