It is very common for a classroom to have a world map on the wall．However，a new map，called the AuthaGraph World Map，might replace the old maps． （1）

This surprised many because earlier winners of the important award have been things like robots and mobility chairs （移動座椅）．
   But this map is very special，because it is more accurate than the maps you have used at school．This is because it is difficult to copy the 3-D，spherical surface （球面） of the world onto a 2-D map．（2）

This means places like North America look much bigger than they really are．North America looks the same size as Africa，even though Africa is much bigger． （3）

Created by Japanese designer Hajime Narukawa，it cuts the globe into 96 equal triangles and puts them into a tetrahedron （四面體） shape．In this way，the designer keeps the proportions （比例） of the land and water the same when going from a 3-D sphere to a 2-D map．
   The map is already being used in Japanese school textbooks．According to the Good Design Award judges，it is the best example of what the planet really looks like． （5）

A．However，they did suggest increasing the accuracy further by cutting the world into even smaller pieces．
B．It recently won Japan's 2016 Good Design Award．
C．Similarly，Alaska looks bigger than Brazil，even though Brazil is more than five times bigger in real life．
D．It recently becomes very popular in Japan and catch much attention．
E．That means the body of the world has been changed．
F．Bodies of water and land are distorted （變形） because of this．
G．The AuthaGraph World Map appears to have solved the problem using geometry．
