At the beginning, written Chinese was a picture-    1     language. It dates back several thousand years to the use of longgu-animal     2     and shells on which     3     were     4     by ancient Chinese people.

In ancient times, silk from China found its way overland to India, the Middle East and Rome, along what became known as the Silk Road. A trading route across the sea was also     1     along the coasts of the Indian Ocean centred around Ceylon (now Sri Lanka). Here, merchants from China and many other places met to     2     trade deals, which also led to more     3     of each other’s cultures. Over the centuries, further trading allowed more exploration of the regions to the west of China, as     4     in Du Huan’s Record of My Travels in the eighth century.

Later, the Ming Dynasty further     5     relations with these regions. Between 1405 and1433, seven large fleets sailed west on voyages of trade and exploration. These fleets were a sight to behold and were in a league of their own at that time. Under the     6     of Zheng He, they set sail from the South China Sea across the Indian Ocean to the mouth of the Red Sea, and then to the east coast of Africa. African     7     families sent gifts such as giraffes as gestures of friendship in     8     for gold, silk, and spices. Although China     9     from further expeditions after 1433, these land and sea routes remained     10     channels between other cultures for centuries.

But by any criteria this work is worth it to us as well, because it shows that we are global citizens     1         2         3         4    , and that we feel responsible for others and are ready to build a community with a     5         6         7         8    .

As a player, Lang Ping brought honour and     1     to her country. As a coach, she led the China women’s volleyball team to     2     at world championships and the Olympics. As a person, Lang Ping is loved by fans     3         4         5         6    . When the Chinese team was preparing for the 2015 World Cup, her determination was     7    . The team that Lang ping had built was     8         9    . One of the best players had been     10    , and the team captain had to leave     11         12     heart problems. Losing two important players was a big     13    , but Lang Ping did not     14         15    . She had faced difficulties before, and she knew that her young players could win if they     16         17     as a team. Two weeks later, they were world champions! Then in 2016, Lang Ping led her volleyball team to Olympic gold in Brazil.

I recommend that you talk to your friend about his behavior. It is not unusual for teenagers of your generation to     1     computer games and the online world. But spending too much time online is unhealthy and makes it very difficult to focus on other things in life. Some students even     2     the Internet and cannot     3     school and family life.

Tu Youyou, a committed and patient scientist, was born in Ningbo, China, on 30 December 1930, and graduated from Peking University Medical School in 1955. After she graduated, she worked at the China Academy of Traditional Chinese Medicine in Beijing. In 1967, the Chinese government formed a team of scientist with the o    1     of discovering a new treatment for malaria, and Tuyouyou was among the first r    2     chosen. In the beginning, Tuyouyou went to Hainan, where malaria was more common, to study malaria patients. In 1969, she became the head of the project in Beijing, and decided to review ancient Chinese medical texts to find traditional b    3     treatments for the disease. Her team examined over 2,000 old medical texts, and e    4     280,000 plants for their medical p    5    . From their research, they discovered and texted 380 d    6     ancient Chinese medical treatments that showed promise in the fight against malaria.

One medical text from the fourth century suggested using the extract from sweet wormwood to treat a fever. Tu’s team tested a collection of dried wormwood leaves but found no effect. They then tried boiling fresh wormwood, and using the l    7     obtained from this to treat malaria, but this did not work either. Their project get stuck. However, Tu Youyou would not a    8     defeat. She analysed the medical texts again, and by chance, she found one sentence suggesting a different way to treat the wormwood. She concluded that boiling the sweet wormwood apparently destroyed its medical properties. Using a lower temperature to draw out the extract, she found a s    9     that worked. After failing more than 190 times, the team finally succeeded in 1971. Tu Youyou and her team members even i    10     on testing the medicine on themselves to make sure that it was safe. Later, the medicine was tested on malaria patients, most of whom recovered. This medicine, which was called artemisinin, soon became a standard treatment for malaria.
