The Great Wall of China is one of the greatest wonders of the world. With a history of more than 2,000 years, some parts of the Great Wall have {#blank#}1{#/blank#}. It is, however, still a very popular place of interest.

It is the {#blank#}2{#/blank#} wall ever built. It's from Shanhaiguan on the east coast to Gansu Province in the {#blank#}3{#/blank#} of China. It is about 8 meters high. The top is 8 meters {#blank#}4{#/blank#} and it gets even wider towards the bottom where it is 15 meters. It is made {#blank#}5{#/blank#} stone and brick. The top is hard enough for men on horseback to ride on. The wall was built by hand and it took {#blank#}6{#/blank#} of years to finish.

No one knows {#blank#}7{#/blank#} when the building of the Great Wall was started. It is believed that the wall was built to {#blank#}8{#/blank#} parts of the country during the Zhou Dynasty. Emperor Qin Shihuang joined the separate walls built by the Qin, Yan and Zhao Kingdoms. The wall was not only for protection in the north, it was also a {#blank#}9{#/blank#}of China's ancient civilization (文明).

Today, many of the visitors go to see the wall. {#blank#}10{#/blank#}they stand on top of a tower and look down on this wall, they can't help (禁不住) saying “Wow, that's fantastic!”
