iv. background information
1. the great wall of china
in 221 b.c. the first emperor started to build a great wall right across the north of his empire. he wanted to keep the tribes of huns and tartars outside his country. there were earlier walls built in some places by different kings of china, but the first emperor, now that he ruled all china, decided to complete the wall. he decided to make it run right across from tibet to the sea, a distance of over 1 500 miles. it took seven years to build.
the great wall ran across wild, steep, mountainous country, over the mountains and down the valleys. north and west of it there were only wild mountains and deserts, and south and east there were the rich yellow river plains. it was built higher than a double-decker bus. in most places it was wide enough for eight men to march side by side along the top. it was built of stones and clay. there were huge blocks of stones on the sides, and on the top there were more stones. cars could travel along the top.
