China’s tea culture can be traced as far back to before 2000 BC. The Shennong Emperor discovered tea when a leaf fell into boiled water he was drinking, beginning a tradition that still     1     (exist) nowadays.

During the Tang dynasty(618-907) in China, the culture of tea underwent a remarkable development. When Emperor Lu Yu     2     (author) the highly regarded Classic of Tea (茶经), he set off on a journey that would play a critical role in establishing tea’s cultural     3     (significant) in China. Lu Yu, a monk who later earned fame     4     the’Sage of Tea’ (茶圣), had an enormous impact on the spread of tea drinking and linked     5     to Buddhist ideas, including the harmony and mysteries of the universe. The Classic of Tea is the oldest     6     (know) guide to tea drinking and culture. It covers all aspects of tea culture, from growing to harvesting, producing as well as techniques for farmers and craftsmen     7     (produce) the finest teas.

Throughout the Tang dynasty,     8     culture of tea drinking spread quickly among scholars. Inspired by Lu Yu’s ideas, they added medicinal qualities to tea, praised for     9     (sharpen) the mind. At the same time, wine was falling out of favour for their alcoholic properties, paving a path for tea to spread throughout society     10     to be used in religious occasions and offerings.

3 . As archaeologists (考古学家) examined ancient tombs in Turfan in western China, they discovered some surprisingly well-preserved and familiar relics. Though hardened from over 1,000 years, there sat little dumplings.

Exactly who invented dumplings remains a mystery. But some scholars suspect they were first spread by nomadic (游牧的) Turkic peoples living in western China and Central Asia. This is thought to be the case because “manti,” meaning “dumpling” or “steamed bun” in many Turkic languages, appears to be the root word for dumpling in several other languages. Ancient Turkic people probably filled their dumplings with meat. But it’s unclear when this practice began, or whether they learned the art of dumpling-making from others. However this happened, dumplings certainly gathered steam in ancient China.

Dumplings continued to take off and diversify in China over the next thousand years. Instead of the traditional meat filling, some communities chose vegetarian (素食) dumplings. People developed new cooking methods. The relationship between Chinese dumplings and those in other areas is tricky to trace, but food historians have made their best guesses based on available clues.

Besides Turkic tribes, some scholars believe that the Mongol Empire also contributed to the spread of dumplings, perhaps introducing them to parts of Eastern Europe. These dumplings could have come by way of China or directly from some of the Turkic peoples the Mongols hired to run their empire. One theory is that this gave rise to dumplings like pelmeni in Russia, pierogi in Poland and vareniki in Ukraine. The Mongol Empire also controlled Korea and might have likewise introduced dumplings there. Later, after Chinese dumpling varieties were introduced to more countries, English speakers began calling them dumplings, which means “little lumps”. During the Second World War, Chinese “jiaozi” were brought to Japan. So what about the Italian dumpling-like pasta? Some historians think it might be brought by Arab conquerors.

It’s unlikely that all dumpling dishes came from the same root tradition. However, we can appreciate the mysterious historical web that made dumplings so various.

Deep in the jungle, the Maya built an empire (帝国). And now, scientists are unlocking more secrets about this ancient civilization with the     1     (discover) of 417 cities dating back to 2,000 years ago, said The Washington Post. The cities were found to be connected by 110 miles (177 kilometers) of “highways” in May. They     2     (consist) of the “world’s first-ever extensive system of highways”. The “highways”, as Reuters reported, were     3     (space) stone roadways. Plus, scientists also found pyramids, ball game courts and water     4     (engineer).

The Maya civilization was “far more advanced than we thought”, noted The Washington Post. The new findings showed that they were already busy     5     (create) cities in world history at the time, CNN reported. They did all this in a jungle environment,     6     is rare and impressive. They had to clear rainforest areas     7     (farm) and built large underground reservoirs to store rainwater.

    8    , by 900 BC, many Maya cities were abandoned, calling an end     9     the empire. Scientists still don’t know why. With new forms of technology, maybe this mystery and others could     10     (uncover), telling us even more about this fascinating civilization.

Xi’an, capital city of Shaanxi, served as the capital of 13 dynasties in Chinese history, which in total     1    (last) about 1,100 years. Consequently, the ancient history of Shaanxi is to some degree the ancient history of China. Shaanxi History Museum considers     2     a duty to be a showcase of Chinese ancient civilization.

People call Shaanxi History Museum “Bright Pearl in Ancient Capital and Precious Treasure of China”, for it is an art palace     3    (full) showing Shaanxi history and culture as well as Chinese ancient civilization. Its architectural buildings and exhibits have made it famous as a first-class museum in China     4     it was opened to the public in 1991. It covers     5     total area of 65, 000 square meters.

The basic halls in the museum are divided into three exhibition halls     6     2,000 cultural remains to display the history of ancient times in chronological (编年的) order. The first exhibition hall     7    (locate) on the ground floor while the other two are on the second floor.

While     8    (design) the buildings in Shaanxi History Museum, the great designer used     9    (tradition) palace construction of Tang Dynasty for reference. Adopting symmetry axis (轴对称) layout with main and supporting buildings in order, the complex     10    (architecture) show the unique presence of Tang Dynasty.

The recent opening of a new exhibition building at the Sanxingdui Museum, in Guanghan, in Sichuan province, made the place     1     instant tourist hot spot. The bronze heads, golden masks, holy trees and various statues reveal the    2     (mystery) faces of a culture dating back more than 3,000 years.

For those who cannot make it to Guanghan,     3     the extensive site of Sanxingdui is located, an immersive exhibition     4    (equip) with digital technology, titled Hello Sanxingdui,     5     (offer) an alternative means to be awed by the magnificence of this Bronze Age culture. It is running at the Longfu Art Museum in Beijing until Feb 29.

It provides a time-travel experience for both an educational and artistic appeal. The journey begins     6     a brief timeline of texts, photos and videos, showing how Sanxingdui was first discovered in the 1920s, when objects were found by farmers digging an irrigation ditch (灌溉沟渠); and it highlights the important moments in the past century’s continued archaeological efforts, to reveal the myths surrounding Sanxingdui and the secrets yet     7     (uncover).

On show     8     life-size reproductions of dozens of astonishing artifacts, supervised by Sanxingdui Museum, such as 2.6-meter bronze statues, 3.8-meter-wide bronze masks and “the holy tree” standing nearly 4 meters.

Images of these objects found at Sanxingdui and their     9     (pattern) have been digitalized, animated and projected on screens, leading the audience into the ancient kingdom of Shu, a     10     (civilize) that thrived for centuries in the southwest during the Zhou Dynasty, and disappeared suddenly, leaving many myths and legends.

9 . A national park is an area set aside by a government for the preservation of the natural environment. The national parks in the United States and Canada center on the protection of both land and wildlife.     1     And those in Africa primarily protect animals.

It is widely thought that the idea of a park or nature reserve under state ownership started in the United States in 1870.     2     Yosemite, Sequoia, and General Grant National Parks were established in the United States in 1890. And the U. S. National Park Service (NPS)was created in 1916 to manage the parks.     3     In addition to national parks, the system included national preserves, seashores, historic parks and sites and so on.

Partly following the American example, movements supporting national parks sprang up in many other countries.     4     . And Canada set up its first three national parks in the mid-1880s. The establishment of modern national parks and nature reserves gained momentum (动力)only after World War I or, in some cases, after World War II in Europe. Great Britain established the administrative machinery for both national parks and nature reserves in 1949.     5    

But interest in parks came later in Asia and Latin America than it did in the Anglo-American countries and Europe.
