The Tokyo 2020 Olympics,     1     sponsorship revenue (赞助收入) has exceeded $3.1 billion,     2     (reschedule) to be held from July 23 to August 8 in 2021 due to the COVID-19 pandemic,     3     (shorten) the Olympic marketing period for the Beijing Winter Olympics—to be held in February 2022—by a year. 

Ren Hai, a professor at the Olympic Research Center, claimed on Tuesday, “There will of course be     4    impact, but I think the impact will be limited, as the Summer Olympics and Winter Olympics are different in terms of sports and disciplines,” Ren said. “    5     (history), the two different Olympics were hosted very close together.” Ren     6     (refer) to the period from 1924 to 1992,     7     both the Winter and Summer Olympics were held in the same year.

He Wenyi, executive director of the China Institute for Sports Value, said the reason     8     the limited impact on Winter Olympics marketing is     9     China has relatively few winter sports stars. “The promotional events of Beijing 2022 are unlikely     10     (affect), as the COVID-19 is under control in China.” He Wenyi added.

Australia was always a country I wanted to visit so I saved up some money and     1     (take) the plane for Australia at     2    end of the school term.

It was strange when I arrived. It was the start of winter! Happily for me the weather was still hot and sunny though.     3     also took me a while to get used to the time difference.

The country is     4    ( true) beautiful, full of wildlife you wouldn’t find anywhere else in the world. I visited a koala sanctuary (考拉保护区) in Brisbane —- there were koalas everywhere     5     (sleep) in the trees and I even got the chance     6     (hold) one. I learnt lots of     7     (fact) about koalas, too. For example, koalas can sleep for up to 22 hours a day. At the sanctuary there were also kangaroos (袋鼠) that we     8    (allow) to feed. They were really cute and friendly.

Another exciting part of my trip was snorkelling (潜泳) in the Great Barrier Reef, as the water was very clear and blue. I was also lucky to see some     9    ( interest )sea animals.

I loved visiting everywhere from the beautiful mountains and waterfalls in the National Parks     10    the long white sandy beaches. It’s a beautiful country and worth visiting one day if you ever get the chance.

In much of Asia, especially the so-called “rice bowl” cultures of China, Japan, Korea,     1     Vietnam, food is usually eaten with chopsticks.

Chopsticks are usually two long, thin pieces of wood or bamboo. They can also be made of plastic, animal bone or metal. Sometimes chopsticks are quite artistic. Truly elegant chopsticks might     2     (make) of gold and silver with Chinese characters. Skilled workers also combine various hardwoods and metal     3     (create) special designs.

The Chinese have used chopsticks for five thousand years. People probably cooked their food in large pots,     4     (use) twigs (树枝) to remove it. Over time,     5     the population grew, people began cutting food into small pieces so it would cook more quickly.

Food in small pieces could be eaten easily with twigs which     6    (gradual) turned into chopsticks.

Some people think that the great Chinese scholar Confucius,     7     lived from roughly 551 to 479 B.C., influenced the     8     (develop) of chopsticks. Confucius believed knives would remind people of killings and     9     (be) too violent for use at the table.

Chopsticks are not used everywhere in Asia. In India, for example, most people traditionally eat     10     their hands.
