Roujiamo is closely associated with the north-central city of Xi’an in Shaanxi Province. Since 210BCE, Xi’an has been both the eastern terminus of the Silk Road and the capital for 13 more-or-less Chinese     1     (dynasty).

The meat preparation used to make the filling for roujiamo traditionally     2     (date) back to the Warring States Period. The introduction into China of Central Asian-style flat breads, like the kind used in roujiamo, is often credited to Ban Chao,     3     Chinese general who spent more than 30 years     4    (battle) an association of tribes during the 1st century to regain control of the     5    (far) western reaches of China.

Every family has its own roujiamo recipe, but there are some constants (不变的事物). First comes the lazhi, which includes a list of spices: ginger, star anise, cassia and so on. A special importance     6    (place) on aged stock (陈年老汁). Once the stock is made, thick slices of pork take     7    (they) turn in the pot, simmering(炖) for hours. The flatbread bun, called baijimo, takes its name from     8     is today known as Baiji township.

To be sure, roujiamo is far     9     the perfect food. It’s risky to eat on the go. One has to use both hands     10     (eat) roujiamo; otherwise, the filling is going to launch out from both sides of the burn.

The Maritime Silk Road Museum of Guangdong (MSRMG) in Yangjiang, South China’s Guangdong Province, is China’s first museum to focus     1     underwater archaeology (考古学). The museum has become the home of the ancient ship, now known as the Nanhai I, and continues to tell the story of the Maritime Silk Road     2     began 800 years ago.

“Unlike many other Chinese museums that contain     3    (various) of relics, the MSRMG is dedicated to Nanhai I culture,” museum expert Li Yiyang said.

Ye Daoyang, the deputy director of MSRMG’s Underwater Archaeology and Technology Department, said that the Nanhai I will     4    (eventual) become closer and closer to people.

As the world’s longest man-made canal, the Grand Canal is a vast waterway system in the north-eastern and central-eastern plains of China,     1     runs from Beijing in the north to Zhejiang Province in the south.

The Grand Canal (大运河) is one of the greatest hydraulic (与水利系统有关的) projects in human history,     2     (stretch) 1,794 kilometers. Constructed in sections from the 5th century AD onwards, it was built as a unified means of communication for the empire for the first time in the Sui Dynasty. By the 13th century it consisted of more than 2,000 km of artificial waterways, linking five of China’s main river     3     (basin). The canal was     4     important factor for the economy, social     5     (stable) and government functions in ancient China. It also helped the evolution of Chinese culture by enhancing communication     6     the south and the north.

It is widely acknowledged     7     the Grand Canal is precious heritage passed down to us by our ancestors and is flowable culture that should     8     (preserve). China will continue to carry out     9     (integrate) regional development strategies for the Beijing-Tianjin-Hebei region, the Yangtze River Economic Belt, the Yangtze River Delta region, and the Guangdong-Hong Kong-Macao Greater Bay Area and draw up a new national policy for environmental protection and high-quality development in the Yellow River basin. The purpose is     10     (seek) greater cooperation of opening-up among different parts of the country.

7 . If you’ve ever eaten a free doughnut (甜甜圈) on the first Friday in June, you’ve celebrated the Doughnut Lassies- whether you realized it or not, National Doughnut Day was established to honor the Salvation Army volunteers who fried sugary snacks for World War I soldiers on the front line.

When the US entered World War I in 1917, the Salvation Army, a charity organization, sent about 250 volunteers (who were mostly women) to France, where the American army was stationed. The plan was to bring treats and supplies as close to the front line as possible. But the closer the volunteers got to the action, the fewer resources they could access.

Margaret Sheldon and Helen Purviance were credited with bringing doughnuts to the Wester Front. They had a handful of ingredients, including flour, sugar, animal fats, baking powder and canned milk. Doughnuts were one of the few sweet foods they could make without an oven, and once they had a fire hot enough to heat the oil, they could fry them up fast. The women had the pan to cook them in, but for other parts, they had to get creative. For example, grape juice bottles became rolling pins (擀面杖) when necessary.

Sheldon and Purviance’s pan could fit seven doughnuts at a time, and on day one, they made just 150 doughnuts for the group of 800 men. The soldiers even fought over a doughnut. Then they made some changes to their operation, and eventually made 5,000 doughnuts a day. The snacks were so popular that the volunteers earned the nickname “ Doughnut Lassies”, while the soldiers they served were nicknamed “Doughboys”.

The Doughnut Lassies’ impact didn’t end with World War I. The American soldiers’ experiences overseas made doughnuts a commonly eaten food for them back home.

8 . The Oldest Cookbooks from Libraries Around the World

Libro de arte coquinaria

The Library of Congress

The 15th-century Libro de arte coquinaria, or The Art of Cooking, is the work of Maestro Martino da Como. Martino was known for cooking for his employer. Along the way, he achieved fame as “the prince of cooks.” Martino’s work is significant for another reason too. In the 15th century, his recipes made up a major part of the world’s first printed cookbook, Platina’s De honesta voluptate et valetudine.

Shanjia Qinggong

The Harvard-Yenching Library

Harvard-Yenching owns a 17th-century copy of the Simple Offerings of Rural Households (Shanjia Qinggong). Containing over 100 recipes, Simple Offerings is probably the earliest surviving cookbook in Chinese. The author, Lin Hong, was a man of letters who lived in the Southern Song Dynasty. Lin evidently preferred vegetarian foods, as most of his recipes were plant-based.

Wushi Zhongkui lu

The Harvard-Yenching Library

Harvard-Yenching is also home to a 17th-century copy of the Cooking Manual of Madame Wu (Wushi Zhongkui lu), one of two surviving cookbooks by a Chinese woman before the 20th century. Unfortunately, few of Madame Wu’s personal details are known. Scholars guess that she lived in the larger Shanghai region during the Southern Song Dynasty. Madame Wu apparently had a weakness for sweets, as she devoted a full chapter of her cookbook just to desserts.

Complete Kitchen and Cellar Dictionary The Oslo Public Library

The Oslo Public Library, known as the Deichman Library, has a 1716 copy of the Complete Kitchen and Cellar Dictionary, written by the German writer Paul Jacob Marperger. It belonged to a Norwegian lawyer named Johan Fredrik Bartholin, who donated it to the city of Christiania (the former name for Oslo) in 1784. The book has been in the Deichman collection since it opened in 1785.

1. Who greatly contributed to the world’s first printed cookbook?

A．Lin Hong.	B．Paul Jacob Marperger.

9 . While DNA from animal bones or teeth can cast light on an individual species, environmental DNA enabled scientists to build a picture of a whole ecosystem.

A core of ice age sediment (沉积物) from northern Greenland has yielded the world’s oldest sequences of DNA. The 2 million-year-old DNA samples revealed the now largely lifeless polar region was once home to rich plant and animal life — including elephant-like mammals known as mastodons (乳齿象), reindeer, hares, lemmings, geese, birch trees and poplars, according to new research published in the journal Nature on Wednesday.

The finding is the work of scientists in Denmark who were able to detect and restore environmental DNA — genetic material drop into the environment by all living organisms — in tiny amounts of sediment taken from the Copenhagen Formation, in the mouth of a strait in the Arctic Ocean in Greenland’s northernmost point, during a 2006 expedition.

They then compared the DNA pieces with libraries of DNA collected from both extinct and living animals, plants and microorganisms. The genetic material revealed dozens of other plants and creatures that had not been previously detected at the site based on what’s known from fossils and pollen records.

“The first thing that blew our mind when we’re looking at this data is obviously this mastodon and the presence of it that far north, which is quite far north of what we knew as its natural range,” said study co-author Mikkel Pedersen.

The mix of temperate (温带) and Arctic trees and animals suggested a previously unknown type of ecosystem that has no modern equivalent — one that could act as a genetic road map for how different species might adapt to a warmer climate, the researchers found.

Love Dalen, a professor at the Centre for Palaeogenetics at Stockholm University, said the finding “pushed the envelope” for the field of ancient DNA. “Also, the findings that several temperate species (such as relatives of spruce and mastodon) lived at such high latitudes are exceptionally interesting,” he added.

Further study of environmental DNA from this time period could help scientists understand how various organisms might adapt to climate change. “It’s a climate that we expect to face on Earth due to global warming and it gives us some idea of how nature will respond to increasing temperatures,” he explained.

A．It makes it easier to understand individual species.

B．It is a collection of DNA from all kinds of living things.

C．It includes DNA of mammals living 2 million years ago.
