To solve the problem of scanning codes for residents     1     smart phones, especially the elderly, the government of the Meilisi Daur district of Qiqihar, Heilongjiang province has worked with local public security departments     2     (promote) the “reverse scanning (反向扫码)”.

A card with a personalized QR code     3     (show) before residents enter a facility and staff from the facility should scan the code with     4     application.

“In the past, I often felt embarrassed when I visited a public place because I didn’t own a smart phone and I didn’t know how to scan codes, either,” said Gao Changyong, 73, a     5     (retire) worker. “I had to wait for the staff to write down my information, which caused much more     6     (convenience) than scanning codes.”

“Sometimes we had to queue up outside, which was insufferable, especially in the     7     (extreme) cold winter,” he said. “Therefore, daily     8     (supply) were sent to me by my children so I could avoid going out.”

“When the community worker told me the new method, I was really happy and immediately     9     (submit) my application,” he said. “I received the card just a few days later,     10     that made my life more efficient.”

Ivana is an International student from Tsinghua University. Born in the middle of war, she     1     (force) to move to Serbia with her family. After the war, she returned to Bosnia where she was     2     (unfortunate) raised by a single parent. Her mother was the only figure     3     provided for her and kept her     4     the right track.

During the COVID-19 outbreak, she got the best opportunity     5     (understand) China. She saw     6     (million) of people united with one goal- to win the battle against the COVID-19. She has never seen such a collective dedication from a nation,     7     (turn) things for the better by sacrificing personal convenience.

Over the past year, she has been actively engaged in searching international connections in     8     healthcare industry, first for China and later on for her own country. Thanks to the network she built through Tsinghua, she was able to organize donation of personal protective equipment for both China and her own country.

“Every graduating student has their own unique experiences and stories,” Ivana said at the graduation ceremony, “but I believe we all have had a     9     (reward) experience in Tsinghua.” She would very much like to extend her gratitude to Tsinghua University, to the Chinese government, and to the great civilization with the       10     (wise) of self-discipline and social commitment.

One of the biggest themes at this year’s CES tech show was electric and autonomous transportation — cars, trucks, bikes, boats. And, it turns out, tractors.

Farm-equipment giant Deere showed a new autonomous tractor with     1     attached tillage (耕作) tool at CES. For those not familiar     2     farm life, Julian Sanchez, Deere’s director of emerging technologies, says that tillage is an     3     (importance), time-consuming, and tiring process of preparing the soil for next season s planting. If you don’t do it fast, the ground could freeze. And     4     (effective) tilling means some seeds won’t take and yield (产量)     5     (drop).

While automatic driving has been on tractors for several     6     (year ), Deere’s autonomous tractor can operate without. a driver in the cab. The tractor can detect obstacles     7     might damage the attached tiller. And, he says, it can run around the clock, saving time and labor, and improving productivity by as much as 20%.

If the tilling is too shallow, you don’t break up the straw too deep, and the tractor moves too     8     (slow), increasing fuel costs. This system includes six cameras to detect holes, rocks, or other materials,     9     (inform) the farmer when an issue needs to be addressed. Eventually. Deere expects     10     (add) other tasks to the autonomous tractor.

China’s record-setting Shenzhou 13 missionis in the books.

After orbiting Earth for six months,     1     three crew members of China’s Shenzhou XIII mission have departed     2     the Tiangong space station and returned to the mother planet on Saturday morning, finishing the nation’s     3    (long) manned spaceflight.

Shortly after landing, all three astronauts radioed that they were feeling fine after their long space mission, bringing     4    (applaud) from the China National Space Administration’s mission control center in Beijing.

Shenzhou 13 set other national marks as well. For example, the mission’s Wang Yaping became the first woman to live aboard Tianhe and the first Chinese woman ever     5     (conduct) a spacewalk.

Wang was joined on Shenzhou 13 by Ye Guangfu and Zhai Zhigang,     6     commanded the mission. They were very busy during their six months in orbit. The astronauts — or taikonauts, as Chinese spaceflyers are called — performed two spacewalks, conducted more than 20 different scientific experiments and delivered two live     7    (education) lectures from Tianhe.

The Shenzhou 13 crew also spent some time     8    (get) Tianhe ready for its next round of visitors, which will arrive     9    (relative) soon; the Shenzhou 14 mission     10    (expect) to launch in early June.

On Tuesday China launched a spacecraft, called Chang’e-5, to collect soil and rock samples from the moon. If the journey is successful, China will be the third nation     1     (bring) pieces of the moon back to Earth.

    2     China stepped into space much later than the United States and the Soviet Union, the country    3     (make) huge progress over the past decade, and becomes one of    4     (advance) nations in the world in terms of space exploration. Over the long term, some of Chang’e 5’s operations will help to accumulate and demonstrate modern technologies for future Chinese manned lunar journeys.

It has been four decades since lunar samples    5     (carry) to Earth last time. Planetary scicentists are waiting eagerly for the day more samples will be brought back to Earth.     6     the samples collected by Chang’e-5, scientists can measure radioactive elements in the rocks and     7     (precise) calculate when a volcanic eryption occurred, which will make major     8    (contribute) to the understanding of the solar system’s evolution.

The mission is the latest step in an ambitious space program     9     China hopes will end with an international lunar research station and ultimately a human colony on the moon by the 2030s . China’s achievements in space have become a source of national pride,    10     (emphasize) the Communist Party’s strong and steady leadership.

White Cane Safety Day is an observance celebrated on October 14 of each year since 1964. It is a day of the White Cane, a tool that allows the visually impaired (障碍) people to travel independently and get     1     (identify) easily.

The White Cane     2     (introduce) by an American man called George A. Bonham. One day, he watched a man who was blind     3     (attempt) to cross a street. The man’s cane was black and motorists couldn’t see it, so Bonham proposed painting the cane white with a red stripe to make it more noticeable. The idea quickly     4     (catch) on around the U.S.,making the White Cane an important tool for blind people to move     5    (safe).

Today, there are about 17,000,000 people with visual impairment in China, over 8,000,000 of     6     are blind. It is important that people raise awareness of their     7     (exist) and help, improve their living conditions.

Modern White Canes are becoming more and more lightweight and high-tech, making it     8     (easy) for them to travel independently.    9     it usually takes more effort for them to receive education and pursue careers. Therefore, it is important that the whole society help create     10     barrier-free environment for them.

With the Chinese government’s initiative to “build a new socialist countryside”, rural tourism is now prospering in my hometown, drawing many     1     (visit) and talents.

Come to my hometown,     2     (locate) in the Linan township of Zhejiang province,    3     you will discover that it is an ideal place     4     (enjoy) rural tranquility (宁静). Driving down the road, you can see a vast pond shining like glass in the sunlight and the     5     (specific) designed homestays (民宿).

However, such great development of rural economy couldn’t have been achieved     6     support from our government. Back in 2018, no one     7     (believe) that people in the dilapidated (破旧的) houses could do wonders. And that was also the year     8     my mom embarked on (着手) a great project of developing rural tourism. For her,     9     can compare with the first cockcrow and the twitter of birds at dawn.

To further develop the rural tourism in my hometown, I hope our government could improve the     10     (conserve) and development of tourism assets (资产). They also need to train rural residents to improve the quality of tourism services.

The female Chinese taikonaut Wang Yaping hit headlines all over the world. Known for     1     (broadcast) a 40-minute live lesson showing space experiments in the Tiangong-1 space lab, she has drawn     2     (globe) attention during her space missions.

“When I was young, my dream was to go beyond the village and to pay back     3     my parents had given me.” Wang recalled. Her space dream started in 2003 when China sent     4     (it) first taikonaut Yang Liwei into space. “I watched the bright rocket flame on TV, and an idea flashed through my mind: When will there be     5     female taikonaut?” Wang said. At that time, she was already a transport aircraft pilot with two     6     (year) of experience. During desert survival training, she     7     (ask) for the same standards as those for males and demanded to train in the pressure chamber (压力舱) for an extra 30 minutes each time. “You can’t catch a break     8     (simple) for being a woman,” Wang said. Her efforts were not     9     vain.

Wang’s lesson painted a space world for children and earned her millions of hits on social media, where she has     10     (know) as a “space heroine”.

On July 19, 2013, a girl who was coming to 10 signed up on Weibo with the nickname "frog princess Gu Ailing," and she has posted some pictures of her different skiing     1     (compete). The nickname came from Gu’s first helmet when she started skiing,     2     was green and had a crown and a pink hair pin on it, according to media reports.

Gu first went into public view on June 6, 2019, when she     3     (announce) on Weibo that she would represent Team China in the Beijing 2022 Winter Olympics. In the same month, Gu changed her     4     (register) nationality from the US to China on the official website of the International Snow Federation (FIS). Due to the sensitivity about     5     (switch) nationality and lack of attention on winter sports, Gu did not attract much enthusiasm in the first place.

Over the next two years, she won 12 gold     6     (medal) for China. More and more people become familiar     7     Gu, a girl who loves to eat dumplings and Peking roast duck,     8    (particular) when they found out that Gu’s Putonghua with a Beijing accent is t4more standard than their own.   And no one in China doubted     9    (she) from a patriotic standpoint. Some have noticed that there's     10     "Chinese dragon" on Gu's sportswear to win the gold medal.

China is known as a state of etiquette (礼仪) and ceremonies. Take the example of an interesting story. Once upon a time, a man went on a long tour     1     (visit) his friend with a swan as a gift. But it escaped from the cage on the way and in his effort to catch it, he caught nothing but a feather. When his friend received this unexpected gift—the swan feather, he was     2     (deep) moved by the sincerity (真诚). Later, the saying “the gift is nothing much, but it is the thought     3     counts,” was spread far and wide.

Gifts are regarded as an important part to show politeness in China.     4     is appropriate to give gifts on     5     (occasion) such as festivals and birthdays. If you are invited     6     a family party, small gifts like wine, tea or candies are welcomed. Also fruit, cookies, and flowers are a safe     7     (choose).

Chinese used to cup one hand in the other before the chest as a salute (致敬). This tradition, nowadays seldom     8     (follow) except in the Spring Festival, has a history of more than 2000 years. Shaking hands, which should be firm and brief but not too strong,     9     (consider) formal greeting behavior in China.

If you follow the usual rules of etiquette in China, there is no need to worry about the cultural barriers, for the warm and friendly Chinese will try their best to respect your customs when     10     (communicate).
