6 . Icehouse and ice ticket

As early as Pre-Qin Dynasty, people used natural ice to keep food fresh and make cold drinks. The Zhou royal court had a specialized department called “ice administration”. They collected natural ice blocks each December to store in the icehouse. During the Qing Dynasty, “ice tickets” were used and they were available only to officials and the rich.

Ice container

The most commonly used cooling tool is called “Jian”, which is a big container filled with ice. It was made of clay in early Chinese history, and was later made of copper (铜). The “Jian” can be seen as an ancient refrigerator, which can be used to make cold drinks.

Hiding food in the well

During the Qin and Han dynasties, for common people, the most common way to cool off is by using their wells. Some families put a pot in the well as a cold closet, or put food in a basket and lowered the basket into the well with a rope.

Herbal drinks

During the Qing Dynasty, taking Chinese herbal medicine was popular in Beijing. In hot summer, some people preferred to drink ice water, some boiled perilla leaves, and liquorice as summer soup to keep off the heat. Ancient people also loved to make lotus seed soup in summer for the benefit of strengthening the body.

Kites nowadays can be seen in parks throughout the world. But     1     is believed that the first kite was invented by the Chinese more than 2,000 years ago. In the beginning, the kites     2     (use) for military (军事的) purposes and defense. Since the Qing Dynasty, kites have been used mostly for     3     (entertain) and celebrations.

For a long time, kites were used only in China and nearby countries. Businessmen     4     visited China took kites to India, Korea and other parts of Asia. Marco Polo was the first person     5     (take) Chinese kites to Europe, after one of his famous trips to China in the 13th century. He was also one of the first     6     (author) who wrote about the kites,     7     (explain) to the Western audience how to use them. They spread from Europe to North and South America as well.

During the 20th century, kite flying festivals became very popular in China. Weifang, Shandong is considered the kite capital of the world and the Weifang International Kite Festival     8     (attract) many tourists from around the world.

10 . 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.
