“This is one of the most important ancient     2     (civilisation), but people in the Western world don't know it,” says Michael Harrower, who has thrown himself     3    the study of the surrounding area. After discussions with the local people, the archaeologists set out     4     (dig) near a village, where they found piles of stone wall spread over fourteen hectares of land, which turned out to be a hill created by     5     (ruin).

According to Michael, future research at the site has the potential to clarify a range of topics, including the rise of one of Africa's first complex societies. Currently, they plan to do a further     6     (investigate) to look     7    this complex, yet still rather mysterious, society.

Reconstructed in the 14th century, the Ancient City of Pingyao,     1     (locate) in China’s Shanxi Province, is     2     exceptionally well-preserved example of a traditional Han Chinese city. The property includes three parts: the entire area within the walls of Pingyao, Shuanglin Temple,     3     Zhenguo Temple.

The postal system of the Han Dynasty consisted     5     three tiers— ting, you, and zhi. Tings were usually set up every two and a half kilometers, providing     6     place for passengers and envoys (使节) to rest on their journey. The distance between two yous was around 15 kilometers, the longest distance a man could cover by foot in a day. A zhi was the     7     (big) post station, set up at a distance of 40 kilometers, the one a horse-drawn carriage could reach in a day.

According to the records, sitting on the Hexi Corridor that connected ancient China and XiYu countries, Xuanquanzhi, the post house     8     (function) for more than 400 years as a hub (枢纽) that delivered mail and     9     (office) documents, as well as hosting envoys and foreign guests. “The Xuanquanzhi Ruins was a beautiful knot on Silk Road,”     10     (proud) said Zhang Defang, founding director of the Gansu Jiandu Museum.

Many people must have read The Art Of War but how many have     1     (true) understood it? What does it have to teach us? This is too big     2     question to explore.

    3     (appreciate) The Art Of War fully, we must first understand who Sun Tzu was. The thing about Sun Tzu is that his whole existence remains     4     (hide) in mystery. Where did he live?

It gives scientists and the public alike their first sight of     4    the sea floor looks like.

In the middle of the 20th century, when continental drift (大陆漂移) met with strong     5     (oppose) from many American scientists, Tharp’s groundbreaking maps made it possible     6    the theory of plate tectonics (板块构造学) to appear.

Tharp began her career at a time when few women     7     (become) scientists, but she was able to take advantage of doors opened by historical circumstances, becoming     8     (unique) qualified to make significant contributions to both science and cartography (地图绘制).

In 1997, the Library of Congress named her as one of the four     9     (great) cartographers of the 20th century. She died in 2006, but countless women scientists     10     (motivate) by her spirit since then.
