How will geography influence your life？For some children around the world，the environment they grow up in has a great influence on their lives.This is the case in Madagascar，an island country in Africa，where a 3 D-printed school is now being built.
    Maggie Grout was just 15 years old when she set up a non-profit （非盈 利的） organization—Thinking Huts.Now 22，she is raising money to build a series of 3 D-printed school powered by solar energy.Maggie took the lead role and worked with university professors（大學教授）through the whole process of building the 3 D-printed school.They chose Madagascar because it needs more schools.Many children in that country don't have the chance to receive education.Besides，it has a lot of sunshine，which can be made into energy to power things.
    Maggie first drew a design for the school.She thought about what things the people needed and where they worked best.
    Next，Maggie found an architect（建筑師）and 3 D printing company for the job.To make it environmentally friendly，they use.a special 3 D printer to build the school，It meant up to 50 percent less concrete（混凝土）used and less CO₂.Also，the school could be completed in just a week.They also used local materials to build the doors，windows and roof.
    What's more，Thinking Huts will get local workers to learn how to use a 3 D printer to build more schools on their own in the future.Maggie plans to print more new schools in other parts of Madagascar because one in five children don't have primary school to attend there.
So far，Maggie's charity has already raised ＄125，000."It's good news to me!Of course，we need more." Maggie told Spring wise website.Doing charity work means a lot and she is glad to carry on with it.
