Have you ever wondered     1     you would do to solve math problems if you didn’t have a calculator or computer or even pencil and paper? People in China have used an ancient counting tool     2     (perform) mathematical operations. The Chinese calculator’s name is “suanpan”, but it is known     3    “abacus” in English. Invented by Liu Hong, abacus is one of the symbols of Chinese people’s wisdom     4     (date) back to the 12th century. Abacus has had a far-reaching influence on science and technology, language, literature, art, architecture and many     5     fields of China and even some areas of the world. Meanwhile, abacus has affected people’s character, such as honesty and diligence. For centuries, this simple counting device     6     (pass) down through different dynasties with its original design and purpose     7     (actual) unchanged. The calculations can be made on it immediately, with the device storing the results in “visual storage” much like a computer display.     8     working with an amount of numbers, an abacus is practically faster, since it has a     9     (good) “keyboard” than the Western calculators. Anyway, the small abacus has made an outstanding     10     (contribute) in the fields of human intellectual development, just as the computer does in today’s society.

The first religions started thousands of years ago,    1    people began to believe in spirits. These spirits were usually believed    2     (control) things such as fire, wind, water and animals. There are many tribes around the world still    3    (follow) this type of religion, and they believe that some spirits are good while    4     are dangerous. The people in these tribes often wear necklaces     5    (make) from animal teeth or bones because they believe that this will protect them     6    sickness and harm. According to the traditional     7    (religion) beliefs of the Karen tribe from western Thailand, there are spirits living in houses, fields, water, rice and trees. They believe that the spirits must all     8     (give) presents of foods because if they are hungry, there will be great suffering and burdens for people to bear. The most important person in the Karen village is the priest and he is consulted     9     (regular) about sacrifices and other     10     ( ceremony).

The United Nations Children’s Fund, also known as UNICEF, is a United Nations organization based in New York. It offers help needed by children all over the world. UNICEF     1     (found) on 11 December, 1946 to provide food and healthcare to children in countries damaged in World War II. Since 1953, the organization     2     (take) up an extended mission to help children in the developing world, including those living with disease or disabilities, and those affected by rapid modernization and environmental     3     (problem). Now, UNICEF has been working to improve the lives of children and their families across 190 countries and territories.

When Costco opened its first store in China in 2019, it wasn't just the hot barbecue chickens and discounted Birkin bags    1    attracted overexcited crowds. A fiery, throat-tingling liquor called Kweichow Moutai also flew off shelves.

    2    1,498 yuan, or $209 for a half-liter bottle, it might not sound like the kind of bargain Costco shoppers usually go for—but in this case, it absolutely was. That price    3    (represent) a sharp discount over Moutai sold elsewhere—that is, if you could get your hands on it. The luxury spirit is so beloved in China, it sold out quickly.

Even amid a global pandemic, Kweichow Moutai, the company that makes the liquor, had     4     outstanding year: its stock surged around 70% on the Shanghai Stock Exchange in 2020. The company is China's most valuable firm outside of technology-worth more than the country's four biggest banks.     5    (globe). its market cap has not only beaten all other alcohol distillers, but also Coca-Cola, which had long held the crown as the world's largest beverage maker by market cap.     6    (value) at 2.7 trillion yuan, or S421 billion, Kweichow Moutai is worth more than Toyota, Nike and Disney, too.

Apart from popularity in China,    7     ,Moutai is still virtually unknown overseas. Almost all-about 97%-of its sales come from China alone, according to its     8    (finance)reports.

So how is a company    9    sells its products primarily in just one country now worth more than some longstanding behemoths? And can Kweichow Moutai, which     10    (describe) in the west as "drinking liquid razor blades," succeed in appealing to non-Chinese consumers?
