Shu embroidery (蜀绣) enjoys a long history in China. As early as the Han Dynasty, Shu embroidery was already famous, enjoying a high reputation as “    1     treasure of Sichuan”. During the Five Dynasties and Ten Kingdoms period, a     2     (relative) peaceful society and large demand provided     3     (advance) conditions for the rapid development of the Shu embroidery industry. Shu embroidery experienced its peak development in the Song Dynasty,     4     (rank) first in both production and     5     (excellent). In the mid-Qing Dynasty, the Shu embroidery industry was formed.     6     the People’s Republic of China was founded, Shu embroidery factories were set up and the craft entered a new period of development.

Shu embroidery     7     (form) its own unique characteristics, since it originated among the common people in the west of Sichuan Province. Shu embroidery has strong expression and artistic effect,     8     features are said as “fine and smooth needlework, simple and elegant colors, graceful and easy lines and the traditional Chinese paintings style”. Altogether, there are 122     9     (approach) in 12 categories for weaving. The embroidery took locally-produced colorful satin (缎子) and threads     10     its materials.

Astronomers have published a major finding    1    (recent): A black hole has been releasing energy from a small star    2    was shredded (吞噬) in 2018, after two years in which it didn’t emit (发射) any such material.

“Super unusual,” said Yvette Cendes, an astronomer at Harvard. “We’ve never really seen this before to this degree.”

Researchers made the    3     (discover) when they used a    4     (power) radio telescope facility to check some two dozen black holes where stars had been shredded after     5    (come) too close to them. Such happenings    6    (call) tidal disruption (潮汐破坏) events, or TDEs.

What they found was that one of the TDEs was emitting energy at an unusual speed    7    at a very surprising time: more than two years after the event.

This behavior is different from what has been observed in black holes before, in two ways. First, the timing: it’s more common    8    (see) radio emissions from black holes within the first few months after swallowing a star. And second, the energy emitted in this case doesn’t quite fit in    9    what astronomers have seen before.

In most cases of black holes swallowing stars, perhaps 99%, the outflow is lower in energy. And in 1% of cases, that outflow, at about half the speed of light, rarely    10     (occur).

The 20th CPC National Congress was held from Oct 16 to 22 in Beijing. Xi Jinping, general secretary of the CPC Central Committee, delivered a report. The document is divided into three parts and 15 sections and contains more than 30,000 Chinese characters.

In January,     1     was decided to set up a     2     (draft) team, with Xi serving as its head. At that meeting, General Secretary Xi demanded that the preparation work fully     3     (grasp) the new features of the times. The document stated: ”China     4     (commit) to its fundamental national policy of opening to the outside world and pursues a mutually beneficial strategy of opening up. In the report of the 20th CPC National Congress, the word “opening-up” was mentioned as many as 29 times. The 20th National Congress of the Communist Party of China (CPC) provides a new opportunity for China’s high-level opening-up to the outside world and new momentum for world     5     (economy) growth. Up to now, China     6     (sign) more than 200 cooperation documents with 149 countries and 32 international organizations under the Belt and Road Initiative (BRI).     7     the 20th Congress report points out: We must strengthen our sense of hardship,     8     (prepare) for danger in times of peace and prepare for a rainy day. While 100 years have passed in the history of the CPC,     9     many successes achieved, the country is now faced with new strategic opportunities in pursuing development.

A strong youth makes a strong country. At this time of their lives, contemporary Chinese youth have a very broad stage     10     (display) their talents and a very bright prospect to realize their dreams.

A robot is any machine that can work     1     (independent) and perform tasks otherwise done by humans. Robots as we know them started out as science fiction (假想之物). The author Isaac Asimov coined the term “robotics” and     2     (come) up with the Three Laws of Robotics. The first of these was that robots may not harm a human being and     3     (scientist) referred to Asimov’s laws when they started making real-life robots.

In 1954, Unimate, a large robotic arm, became the world’s first     4     (industry) robot.

For a long time, robots were only found in factories or laboratories. But later, robots found     5     (they) way into homes and classrooms. Nowadays, robots have become an important part of space missions.

Some people fear that robots will take too many jobs away     6     humans. This process is called automation. However, some experts think that the use of robots will allow businesses     7     (create) more jobs than have been lost. The coronavirus pandemic (冠状病毒流行病) has shown how robots and humans can work together. In Singapore, a robotic dog called Spot has been used to help enforce (执行) social distancing. It was made by Boston Dynamics,     8     has also developed a human-like robot called Atlas. In December 2020, a video showed Atlas and Spot performing a dance routine together.     9     (look) ahead, whether it’s in education, entertainment     10     exploration, we surely believe that robots will play a big part in the future of humanity.

Ocean Park Hong Kong is one of Hong Kong’s greatest tourist     1     (attract). Because the park isn’t run for profit, it is much more suitable for education and wildlife conservation research. And     2     (compare) with other theme parks, it takes better care of the animals. In addition, you will find prices there fairly reasonable considering the size and the quality. Therefore, since its opening, the park     3     (draw) a large number of visitors.

    4     (cover) about a square kilometer on the southern side of Hong Kong Island, the theme park is conveniently close to downtown. As the park attracts large crowds every day, try to be there     5     the park opens at 10 in the morning and avoid the busy holidays and weekends.

I can remember some things about my childhood. Some are unhappy. I remember my first visit    1    the zoo. I saw a lion and    2    eagle. The lion was very lazy, and he    3    (sleep) all the time. He was very    4    (bore) to me. The eagles suddenly flew in the air and frightened me. I started to cry!

Of course some memories are happy. I remember the day when my father tried to teach me how    5    (ride) a bicycle. I wasn't very good at it. I said, “I don't want to do this!" But my father was very    6    (patience) and very soon he taught me how to do it. Now I ride my bicycle every day and I'm much    7    (fast) than my father! And I also remember my first day at kindergarten very    8    (clear). There were so many children! I only knew one of them, a boy    9    (live) in the apartment next door. I was very nervous. However,    10    we started playing with some toys, I soon stopped feeling nervous.
