Beijing Zoo works hard to prevent people from feeding or otherwise harming animals. According to a report in Beijing Daily on Wednesday, those who feed animals in forbidden areas will have to pay 50 to 100 yuan (about $ 7.50 to $ 15) as an official    1    (punish) in accordance with Beijing's park regulations. Normally, food for animals         2    (provide) by zookeepers with the correct nutritional balance. Visitors who feed animals may cause indigestion (消化不良)or    3    (bad). In 2015, three deer at the Shanghai Zoo died after taking    4     uneatable material, including plastic bags    5    (throw) into the cages by visitors.

Since the middle of last month, Beijing Zoo    6    (deal) with more than 300 cases in which animals were fed in forbidden areas. Meanwhile, the zoo has built feeding zones    7    zoo-keepers will regularly provide a certain amount of food visitors can use to feed the animals. "Hopefully,    8    new regulation will effectively stop the ones who like feeding the animals, which in fact is harming    9    (they)," said Zheng Wei, 31, a young mother of a 5-year-old girl. "We should teach our children correctly, rather than just having fun. Many tragedies have already happened because of    10    (proper) feeding.

Chinese scientists have created the world’s first light-based quantum (量子) computer, called Jiuzhang. It’s     1     breakthrough in the field after Google completed its quantum computer last year.     2     (compare) with today’s best supercomputers, Jiuzhang can calculate 100,000 billion times faster.

Usually, information     3     (handle) in binary bits (二进位) by classical computers, presenting itself as either 0s or 1s. However, quantum computers process data using qubits (量子位),     4     is identified as 0s, 1s or everything in between. As a result, as the number of qubits     5     (increase), the computing ability of quantum computers rises too. Another advantage of Jiuzhang is that it’s     6     (easy) to make and maintain. Superconducting quantum computers must be kept at ultra-cold temperatures     7     (ensure) their materials can conduct electricity without any resistance. But most parts of Jiuzhang can operate at room temperature except its sensory equipment and it must be kept at -269.1℃. With advantages     8     traditional computers, quantum computers have a wide range of     9     (apply). The calculations carried out by Jiuzhang can     10     (potential) be applied to machine learning, quantum chemistry and graph theory.

With the approach of the Palace Museum's 600^th anniversary, those     1       (hope) to visit it during the National Day holiday may find     2     difficult to get in. Since the COVID-19 pandemic     3     (break) out, it has limited the ability of visitors to experience the museum     4     person - only 12,000 visitors a day are allowed in. Meanwhile, tickets,     5     can be available 10 days in advance online, also have been sold out immediately. While some     6     (previous) scheduled events have been canceled, visitors can still appreciate three highlighted exhibitions     7     (hold) next month. The exhibitions will present a large number of cultural remains and also give a brief introduction to Chinese aesthetics (美学). Additionally, a series of·    8     (academy) activities, along with the exhibitions,     9     (organize) at the museum. The director of the Palace

Museum hopes that all these activities can raise people's     10    (aware) to treasure and protect our heritage and promote cultural value of this era.

The Chang’e 5 lunar mission is the Chinese National Space Administration's (CNSA) effort to send a robotic spacecraft to the moon to collect samples and return them to Earth for    1     (science) study.

The four-module Chang'e 5 mission — China's first-ever sample-return effort — launched on Nov. 23. A lander and an attached ascent vehicle (上升器)    2    (touch) down near Mons Rümker, a volcanic mountain on Dec. 1. Within.     3    (hour) of landing, Chang'e 5 swiftly got to work. The lander successfully collected 2kg of lunar material, some of    4     was dug from up to 2 meters underground     5     (use) a drill. The sample returned to Earth on Dec. 17, arriving at Siziwang Banner, Inner Mongolia —     6    same site used by the CNSA lo return astronauts home aboard     7    (it) Shenzhou spacecraft.

Chang'e 5 is part of the CNSA's Chang'e lunar exploration program.     8    (name) after a Chinese goddess of the moon, the series of missions aims to     9    (steady) increase their technologies capabilities, laying the groundwork     10    future human landing.

Have you had enough trouble spelling English words? You are not alone. Scholars have argued against the irregularities in English spelling since the 17^th century.

Part of the problem    1     (cause) by the various origins of English words. German, Latin, French and Greek are all common     2     (source), and each follows a different set of rules for spelling.

Some English learners know that     3     (memorize) the Latin roots of English words is a great way to enlarge their vocabulary, as many Latin-rooted words entered English from French after the Norman Conquest (诺曼人征服英格兰). The Normans used French    4     the language of the court, throwing Old English out of official usage for around 300 years. By the time English was again allowed at the court, it was a French-influenced language. There was     5     (actual) no set form of spelling. Until the 15^th century the use of the printing press and the mass distribution (大量流通) of books    6     (freeze) the spelling of words. The spelling system we use today is based on the    7     (pronounce) of that time.

Supporters of English spelling reform argue that replacing words with regular spelling rules will make them easier     8     (remember). Others say that the spelling system, on     9     English is based today, leaves plenty of applications to unlocking the history of the language,    10     (help) readers understand the origins of words.

According to Xinhua News Agency, the Palace Museum and Huawei signed a cooperation agreement on March 15. The two sides will set an example    1    5G application.

The Palace Museum received more than 17 million visitors in 2019,    2    （make）it the most visited museum in the world. In the past 20 years, an office information network covering the whole museum    3    （build）gradually. The museum has developed an App that    4    （provide）an in-depth explanation of cultural relic information and cultural services. Also, the museum has researched on the    5    （apply）of VR, AR, AI in museums.

    6    signing of the agreement marks a new chapter in the strategic cooperation between the Palace Museum and Huawei Technologies Co. So, Huawei will make efforts    7    （speed）up the intelligent construction of the Palace Museum.

"The 600-year-old Palace Museum has never been so close to science and technology." Shan Jixiang said    8    （proud）, former director of the Palace Museum.

Shan shared many ideas about the 5G Palace Museum. With the help of advanced technology,    9    is expected that in the future, audiences around the world will be able to experience and visit the Palace Museum, whether it is a field trip or a virtual tour. Also, the use of AI technology provides a    10    （broad）platform and stronger knowledge support for cultural relics among young people.

On Nov. 8th, four astronauts     1     (get) to the John F. Kennedy Space Center and received the last training. They will go on a trip to the International Space Station (ISS) if weather conditions permit.     2     flight will be the second crew launch for SpaceX, which is a private company and works with NASA to carry astronauts to space.

The first SpaceX flight took place in May 2020 and made history. It was the first time that a private company     3     (send) astronauts into Earth’s orbit. It     4    (successful) carried two NASA astronauts to the International Space Station, who returned to Earth in August after a two-month stay.

Now the company will again transport the astronauts on the next mission. And the astronauts named     5    (they) spacecraft “Resilience” to show the many     6    (challenge), which Americans have faced in 2020. “It’s been a tough year for everybody for a lot     7     different reasons,” crew commander Mike Hopkins said after     8    (arrive) in Florida. They hoped that the name of their vehicle could give a little hope, a little     9     (inspire) and put a smile on people’s face. Then that was     10     they wanted to do.

A video showing a traffic police officer pretending to be blind being denied permission to get     1     a bus with a guide dog has been drawing public attention and has led to     2     (heat) online discussions about the lack of support     3     care for the visually impaired (视觉障碍人士).    4     shown in the video, wearing a blindfold, the officer wasn’t allowed on the bus with     5    guide dog, and was told no dogs are allowed whether they’re guide dogs or not. Some passengers also scolded the officer for making a scene and wasting their time, while the dog appeared very distressed.

The guide dog’s owner Gao Zhipeng, who is visually impaired, told media Monday that this     6     (happen) almost every day since he brought Taobao home in 2014, and it is the same when     7    (catch) a cab. And each time they were refused, Taobao would sink into     8    (depress) for days.

The guide dog being denied     9     (board) is just the tip of the iceberg, compared to the     10     (vary) difficulties faced by the country’s visually impaired population every day when they leave their home.

China, which     1     (recognize) widely as the hometown of tea, gains a big reputation of tea planting, strict tea etiquette (礼节) and unique tea drinking     2     (habit). Tea drinking in China has a history of more than 5,000 years,     3     (date) back to the Shennong era. Tea ceremony has been into    4     (exist) since ancient times. It is the     5     (early) traditional etiquette of the Han nationality in China to offer tea    6    guests. Until now, a cup of tea is always made for guests when they come. A tea party is not only simple and money-saving, but also elegant and formal. The saying “gentleman’s friendship is as light as water”,     7    water refers to tea, indicates a kind of deep friendship. The Han people also have various customs of giving tea as a gift. Every summer in ancient Hangzhou,     8     capital city of the Southern Song Dynasty, each family cooked a new tea called Qijia tea,     9     (primary) together with fine fruits of various colors. Then the tea would be presented to relatives and friends. This custom is putting two green fruits in the tea cup, namely olives or kumquats,     10     (show) the meaning of good luck and happiness.

Great Britain consists     1     four countries: England, Wales, Scotland and Northern Ireland. In the 13th century, Wales     2     (link) to England. In the 17th century, they were joined to Scotland, and happily were united     3     conflict. However, just as they were going to get Ireland connected     4     (form) the United Kingdom, the southern part of Ireland broke away,     5     only Northern Ireland joined with them.

England is the     6     (large) of the four countries and for     7     (convenient) it is divided into three zones: the South of England, the Midlands and the North. You find most of the population     8     (settle) in the south, but most of the industrial cities in the Midlands and the North of England.

London is the capital city with the greatest     9     (history) treasure. It has the oldest port built by the Romans in the 1st century AD, the oldest building begun by the Anglo-Saxons in the 1060s and the oldest castle     10     (construct) by later Norman rulers in 1066.
