With a long history of more than 2,000 years，the Great Wall is now considered to be one

of the greatest wonders in the world. The Wall is 6,700 kilometers long from Shanhaiguan Pass in Hebei Province to Jiayuguan Pass in Gansu Province. The wall is about 7.8 meters high，and it is 6.5 meters wide at the base and 5.8 meters at the top. The Great Wall was first built during the Warring States Period (476-221B.C.) to prevent people in the north from attacking. Then the First Emperor of Qin ordered several hundred thousand workers to connect different sections of the wall. Today，tourists can visit eight sections of the Great Wall. Most of them were built in the Ming Dynasty. The best section of the Great Wall is located near Beijing. 依照文章判断正误(对的写T;错误写F)
