When the Library Cave, known as Cave 17 from the Mogao Cave Complex at Dunhuang, China, was opened in 1900, several tons of manuscripts (手稿) scrolls, booklets and paintings on silk and paper were found literally stuffed into it. These     1     (extreme) valuable writings were collected between     2     9th and 10th centuries CE, by Tang and Song Dynasty Buddhist monks who carved out the cave and then filled it     3     ancient and current manuscripts on topics ranging from religion and philosophy, history and mathematics, to folk songs and dance.

Cave 17 is only one of the 735 human-made     4     (cave) called Mogao Grottoes,     5     were dug into a loess cliff about 15 miles southeast of the town of Dunhuang in Gansu Province. Dunhuang’s long and glorious history reflects     6     (it) significance as a center of     7     (culture) and religious exchange. These caves     8     (dig) and maintained by Buddhist monks from 366 CE and were sealed and hidden about a thousand years ago. It was not until 1900 that they were rediscovered.

The Dunhuang Academy was set up in China in the 1980s,     9     (aim) to collect and preserve the manuscripts; the International Dunhuang Project (IDP) was formed in 1994 to bring the international scholars together     10     (work) jointly on the collections. The IDP has put many of the documents, images and translations online.

Hanfu, meaning “Han clothing”, is based     1     the costumes worn by China’s Han ethnic (种族的) group in the past. Some of the most popular styles are from the Ming, Song and Tang     2    (dynasty).

In recent years, it has become     3    (extreme) popular though there are some opposite views. About three-quarters of Hanfu lovers are between 16 and 24 years old. Members of this generation often see it as       4    way to rediscover Chinese traditional culture. It’s pretty exciting     5    (see) young Chinese people building up their self-confidence and     6    (develop) their individuality (个性) to show the world what they love. For more Chinese, this dress style might become a good starting point to further explore the beauty of China’s long history and rich culture. Li Siting, president of the Hunan Hanfu Culture Promotion Association, often communicates with people from     7    (variety) places. Last year, she     8    (attend) the 7th Chinese music conference in Wuhan,       9    she met overseas Chinese culture lovers coming from Japan, France, Argentina and other places for the first time. Many people think Hanfu is not only the perfect bridge for young people to connect with Chinese culture,     10     a medium to promote Chinese culture.

Poetry probably had its origins in traditional folk music thousands     1     years ago. In that era, there were no TVs or films, and writing had not been invented. As     2     result, people would sit around the fire at night and sing songs     3     (entertain) themselves. These songs reflected themes from the people’s daily lives, such as bunting animals or     4     (sow) crops. Since nothing     5     (write) down at that time, different versions of these songs developed. Each area produced     6     (it) own respective rhythm. In addition to this, people would recite stories of past     7     (hero). As these stories were often quite long, they often had rhyme and rhythm to help people remember them more     8     (easy). While such songs and stories had a very simple format in the     9     (begin), over time they became more complicated and polished. These were no longer the works of amateurs siting around a fire, but works of true poets     10     cared about their art and sometimes made a living from it.

About six years ago I began my job as an IT     1     (consult).   I had always been quite good with computers. It was a great move for me, as I quickly learned a ton. Every day was fun. It was one of the best and most challenging jobs     2     I had ever had.

When thinking of a few years ahead, I realized that things started to taper(逐渐变窄). I wasn’t learning as much as before. I felt a desire to try     3     different. But I couldn’t get up the courage to make any moves. I     4     (pay) very well; I had a lot of freedom, and great benefits. I had grown comfortable and 1 had been accustomed to an easy life.

Last year things came to a head(达到紧急关头). I was having a     5     (true) stressful month,     6     (overload) with work that was neither challenging nor interesting. I had enough. I reached out to my boss and let him know about my idea. We had a meeting about my personal decision. He didn’t want to lose me. He addressed my     7    (concern) and we agreed that I could change my job and begin working on some new internal (内部的) organizational systems. I decided to give this new role a chance.

Now a year after my role change, not much is different. Senior staff did not adopt     8     new systems I built. The work is still uninspiring and unchallenging. Change can be very difficult for some and after spending time trying to carry out new solutions, I’ve realized that you simply can’t change other people     9     they don’t want it.

I’ve again quit my job. I need a greater challenge. I’ve learned a lot     10    my quitting experience.

Chinese scientist Yuan Longping, globally known for developing the first hybrid rice strain in 1973 that served as a solution     1     worldwide hunger, passed away on Saturday at the age of 91.

The scientist spent over five decades researching and improving hybrid rice,     2    has reached its third generation, feeding     3    (approximate) one-fifth of the world's population with less than 9 percent of the world's total land. In China, the annual planting area of hybrid rice has topped 16 million hectares, or 57 percent of     4    total planting area of rice. Its growth area overseas has reached 8 million hectares. His more recent achievements included developing     5    (variety) of seawater rice, or saline-alkali tolerant rice. His team planned to use the rice     6    (transform) 6.7 million hectares of saline-alkali land in China over the next eight to 10 years.

Yuan once said he had two dreams—to “enjoy the cool under the rice crops taller than men” and that hybrid rice could be grown all over the world to help solve the global     7    (short) of food.

Yuan's lifelong devotion to reducing hunger is     8    has made him a national hero and household name in China is. In 1999, an asteroid (小行星)    9    (discover) by the National Astro-nomical Observatories was named after Yuan. In 2019, he     10    (award) the Medal of the Republic, China's highest state honor.
