Originally constructed around 256 BCE by the State of Qin     1     an irrigation and flood control system, Dujiangyan is a remarkable example of ancient engineering skill and is still     2     use today.

During the Warring States period, people who lived along the banks of the Min River     3     (trouble) by annual flooding. Qin governor and irrigation engineer Li Bing investigated the problem thoroughly. He led a team     4     (construct) a levee(堤坝) to redirect a part of the river’s flow. Then they cut     5     channel through Mount Yulei to let the water flow through it. After the system was finished , no more floods     6     (occur). What’s more, it made Sichuan one of the most productive agricultural     7     (region) in China because the redirected water from the Min River could be used for irrigation. If you visit Dujiangyan, you will see an     8    (usual) construction that looks like a fish’s mouth. This famous attraction, Yuzui, together with two other important parts, namely, Feishayan and Baopingkou, was     9     (scientific) designed to control the water flow throughout the year.

    10     (recognize) as a UNESCO heritage site, Dujiangyan has irrigated farms while preventing floods for over 2,000 years.

2 . About one million years ago, the Ice Age began. The Ice Age was a long period of time in which four great glaciers (冰川) pushed southward to cover almost all the upper half of North America, and then melted away. Each glacier was a thick sheet of ice and snow that spread out from a center near what is now Hudson Bay in Canada. The winters were long, and the cool summers were too short to melt much of the ice and snow, The ever - growing sheet built up to a thickness of two miles at its center.

As all glaciers do, these great glaciers slid. They pushed down giant trees in their paths and scraped (刮, 削) the earth bare of soil. Many animals moved farther south to escape. Others stayed and were destroyed.

When winters of little snow came, the summer suns shone into the edges to the ice sheets. As the glaciers melted, rocks, soil and other things that had mixed with the ice and snow were left. New hills, lakes and rivers were formed.

The last of the great glaciers began its melting about 11000 years ago. Its melting formed the Great Lakes. These lakes are today little changed from their early sizes and shapes. The largest of the North American river systems Was also influenced by the glaciers. This is the Mississippi - Missouri - Ohio system. These rivers were miles wide a first. Through the years they settle into their present channels.

The Honghe Hani Rice Terraces(梯田), in southern Yunnan, China, cover a huge 16, 603-hectare area. The terraces,     1    (know)to all of the world now, were made out of a thick forest by the Hani people. The terraces rise at different angles from a shallow 15°    2     a steep 75°, forming a wonderful landscape(景观)that     3    (be)rare in the world.

In 2003, the terraced fields were     4    (official)recognized by UNESCO as a World Cultural and Natural Heritage site. About 1,300 years ago, the Hani people first     5    (come)to the steep mountains. They struggled against the difficult terrain(地形), successfully creating the terraces, where they grew rice in order to make     6    (they) living. Over the past 1,300 years, the Hani people have developed a complex system of channels     7    (bring)water from the forested mountaintops. They show great appreciation for natural phenomena such as rivers, mountains, the sun, fire     8     the moon. They have also created a complete farming system     9     involves cattle, ducks, and fish and supports the     10    (produce)of red rice, the area's main crop.

The landscape changes through the year. In April the terraces are all green as rice starts to grow; in later parts of the year it is yellowish brown as the rice ripens. In February, the terraces become bare earth, with the water reflecting(反射)the sky.

The Xi’an City Wall is the most complete city wall that has survived China’s long history. It     1     (build) originally to protect the city     2     the Tang dynasty and has now been completely restored (修复). It is possible       3     (walk) or bike the entire 14 kilometers.

We accessed the wall through the South Gate. The wall is 12 meters high and from here you can see streams of people moving inside and outside the City Wall.

After     4     (spend) some time looking at all the defensive equipment at the wall, we decided it was time for some action and what     5     (good) than to ride on a piece of history!

We     6     (hire) our bikes from the rental place at the South Gate. My bike was old and shaky     7     did the job. It took us about 3 hours to go all     8     way around the Xi’an City Wall. Supposedly you can do it in two hours, but we stopped at the different gates and     9     (watchtower) to take pictures or just to watch the local people going about their     10     (day) routines.

Many buildings along the Yangtze River have been destroyed during the flood season,     1     the Guanyin Pavilion (亭子) in the middle of the river has continued to stand tall even after more than 700 years. How does this ancient pavilion make     2    ? Described as “the first pavilion on the Yangtze River”, the Guanyin Pavilion     3     (build) in the Song Dynasty and then rebuilt in the Yuan Dynasty. Today, the pavilion     4     (sit) on a piece of dragon-shaped rock in the middle of the Yangtze River. Located outside the city of Ezhou, Hubei Province, the pavilion was constructed on a huge rock about 30 meters from the bank of the river.     5     (face) west, the pavilion is 24 meters long, 10 meters wide and 14 meters in     6     (high) . The base is made with a one-meter- high stone pile. The entire base is     7     (beautiful) combined with the rock, and the whole building is shaped     8     a boat in the direction of the flowing water. More importantly, a very strong stone wall was set up     9     (protect) the main body from the floods. The ancient pavilion is still standing more than 700 years later,     10     shows the wisdom of ancient Chinese people.

6 . “It has nothing in common with anything else on the Bund(外滩) "said Ben Wood, the American architect behind Shanghai's famous Xintiandi District, commenting on the Fosun Foundationafter its completion in 2016. "The great thing about the Bund is that it'sgrand. Perhaps a building that can stand out is needed here to show that acompany is progressive. But it's not grand.”

For now, however, the FosunFoundation ---a new theatre ---is proving popular with riverside tourists.

Located in the Bund FinanceCenter, the theatre was designed by co-operation of two world-known Britishdesign firms: Foster+ Partners and Heatherwick Studio. The architecturalhighlight is the outward appearance ---a golden, three-layered(层) steel bamboo curtain that hangs fromthe third floor. But what makes the architecture really unique is that it"dances" : repeatedly each day, the curtain slowly moves ---opens andcloses--- with music. This visual element, combining East and West, looks likeboth an ancient Chinese crown and a Western harp (竖琴). The building's ground floor entrancelooks unclear, but once inside, you'll see the space reveal a hall and cafe, and traditional Chinese theatres on the upper floors. Although there're onlyfour stories above ground, the building houses several music halls on its threeunderground floors.

“The opportunity to makesomething new in this culturally historic location was extraordinary, "said Thomas Heatherwick, Heatherwick Studio founder. "We tried to make itan interesting addition to show Shanghais mix of modern and historicarchitecture.”

The Fosun Foundation is only part of a bigger plan for this economicand cultural center in China. Along the Huangpu River, a massive waterfront artarea is being built. Shanghai hopes to play a larger role in the global artindustry in the coming years.

What Shanghai makes of thisnew riverside project remains to be seen. But with the Fosun Foundation open tothe public, the area's rapid transformation is bringing up discussions inChina's arts scene and beyond.
