China is widely known for its ancient civilization     1     has continued all the way through into modern times. There are many reasons why this has been possible.

At the beginning, written Chinese was     2     picture-based language. Ancient Chinese people carved     3    （ symbol） on animal bones and shells. By the Shang Dynasty, a well-developed writing system had come into being. At that time, people lived in different places,    4     （ lead） to many varieties of dialects and characters.

Emperor Qinshihuang united the seven major states into one country where the Chinese writing system began to develop     5    one direction. The writing system was of great     6    （important） in uniting the Chinese people and culture. Even today, wherever Chinese people live or whatever dialect they speak, they can communicate    7     （free） in writing.

Written Chinese has also become an important means by which China's present is connected with    8    （it） past. People in modern times can read classic works that    9    （write） by Chinese in ancient times. The high regard for the Chinese writing system can be seen in the development of Chinese characters as an art form,    10    （ know） as Chinesecalligraphy, which has become an important part of Chinese culture. Today, the Chinese writing system is still an important part of Chinese culture.

From China's Changcheng Research Station in the South Pole to Tuktoyaktuk, Canada in the North Pole,   Guizhou runner Bai Bin took 433 days and ran 24,000 kilometers     1     (complete) this journey.

    2       (bear) in Sinan county, Tongren, Southwest China's Guizhou province, Bai     3    (be) a running enthusiast since childhood. In 2006, Bai took 50 days to run from Guiyang to Lhasa. In 2011, Bai took 150 days to run from Istanbul to Xi'an.     4     (he) previous experience in grueling sports laid the foundation for him to push his limits. In 2018,     Bai and his friend Li Zhenyu     5    (plan) the route for running from the South Pole to the North Pole. According to the plan, the route will be by way of 219       6     (city) and towns in 14 countries. His journey started on March 2. 2018. In addition to       7    (run) , the extreme environment posed a major challenge for him.    8    the help of his team, local citizens, and overseas Chinese, Bai overcame massive difficulties and arrived in the North Pole on May 8.

In western countries the only person who might dare to tell you that you are fat is your     1     (person) doctor. Then he would probably tell you how to lose weight. In China, there is no such inhibition (拘谨) as to     2     (talk) about people’s weight. It     3     (be) common for Chinese to go to foreigners, saying, “You are fat.” While talking with     4    Chinese friend about this, she told me that I was wrong and that Chinese will normally say, “You are so fat.” There are several reasons     5     people will say this. Firstly, there aren’t many fat people in China. It is almost a     6     (curious) to see someone fat. Secondly, there are     7     (few) private issues. Thirdly, people just feel freer to speak exactly what is on their mind. Try feeding Western dessert to Asians     8    you will always hear “too sweet, too sweet”. Some Chinese think that all Westerners are fat. Once I     9     (play) basketball when a guy said, “Why are you so skinny?” I thought all people from America were fat.” Perhaps if more people in American comment on others’ weight, then it might help remind people to try     10     (stay) fit.

With a    5    (puzzle) look on my face, I pointed to myself and said, "Me?" She    6    (nod) and said, "Yes,you." I walked to the table and she said," Bring your family here. I can finish eating at the counter. My son is in    7    hurry to leave anyway." My eyes    8    (fill) with tears as she wiped down the table and guided my dad to the seat.

I always believe that there are    9    (nature) kind people in this world.This woman has set a good example to her son,    10    is a really lucky guy.

As a five-year old girl, Lin Qiaozhi was deeply affected by her mother’s death. At the age of 18, instead of following the    1     (tradition) path of marriage, she     2     (choose) to study medicine.

Pei, then the most sought-after architect in America,    1    ( present) his plans for a 70-foot glass pyramid in the l8th-century courtyard of the Louvre, the general     2     (react) was anger. Because Mr. Pei was Chinese-American, he    3    ( apparent) had no understanding of the Louvre, or Paris, or France.

However, these remarks did not annoy him. With quick enthusiasm and wide smiles, he took them. He had been asked to design    4    new entrance for the museum and,    5    everyone's surprise, instead of adding on some concrete block, he had created a great welcoming space: put a winding staircase underground and capped it with a ray of light,    6     did not hurt the old facades (外墙).

9 . The Sydney Opera House has a very interesting history.     1     all started in the 1940s, when the Sydney Symphony Orchestra had nowhere to play. The orchestra’s conductor, Eugene Goossens, asked the Australian government to think about building a place and the government     2     (final) agreed to build an opera house in 1954.

The government held an     3     (nation) competition to find a design for the opera house. Many of the 233 designers from around the world     4     entered the competition were famous, but the design of an unknown Danish architect     5     (name) Jorn Utzom was chosen as the     6     (win).

While drawing up the plans, Utzon remembered the temples he     7     (see) in Mexico before and used them as his inspiration for the base     8     the opera house in Sydney. The building of the opera house began in 1958, but Utzon had still not finished his plans He did not like his first plan as the concrete roof shells did not work. His new idea was     9     (make) the shell shapes on the roof into the shape of a ball. That way, the same ball mould (模型) could be used for several roof     10     (part). In 1962, the government agreed to the new ball roof idea. The building was completed and in November 1973, the Sydney Opera Hope was opened by Queen Elizabeth II.
