\oval{Breaking boundaries}

答案： 第一部分：Words to describe breaking boundaries in various areas
- Science and Technology：Innovation, discovery, paradigm - shift, breakthrough.
- Social and Cultural：Inclusion, diversity - promotion, tradition - re - evaluation, cultural - exchange - enhancement.
- Personal Growth：Self - discovery, skill - expansion, comfort - zone - leaving, mindset - transformation.
第二部分：Write your understanding about Lincoln's talk about the government “of the people, by the people, for the people”
This phrase emphasizes that the government should be composed of the people (representing their interests), operated by the people (through democratic means such as voting and participation in governance), and exist for the benefit of the people (providing services, protecting rights, and promoting the general welfare). It is a fundamental principle of democratic governance that highlights the central role of the people in a just and functional government system.
第三部分：Comment on a person who has helped to increase understanding between two countries
For example, consider Nelson Mandela. He not only fought for racial equality within South Africa but also became a global symbol of reconciliation. His efforts in building a new South Africa after apartheid showed the world the power of forgiveness and understanding. He engaged with the international community, sharing South Africa's story of struggle and hope. His visits to different countries and his speeches promoted cross - cultural understanding. He broke down the boundaries of racism and mistrust, showing that different ethnic and national groups can co - exist and thrive together. His work increased understanding between South Africa and the rest of the world, as well as between different racial and ethnic groups within South Africa.

Chinese Scientist Wins 2015 Nobel Prize
Tu Youyou has become the first female scientist of the People's Republic of China to receive a Nobel Prize, awarded for her contribution to the fight against malaria, one of the deadliest diseases in human history. Thanks to her discovery of qinghaosu, malaria patients all over the world now have had a greatly increased chance of survival.
Born in 1930, in Ningbo, Zhejiang Province, Tu studied medicine at university in Beijing between 1951 and 1955. After graduation, she worked at the China Academy of Chinese Medical Sciences. She completed further training courses in traditional Chinese medicine, acquiring a broad knowledge of both traditional Chinese medicine and Western medicine.
Tu’s education was soon to prove very useful. In the 1960s, many people were dying of malaria, and in 1969 Tu became head of a team that intended to find a cure for the disease. She collected over 2,000 traditional Chinese medical recipes for malaria treatment and made hundreds of extracts from different herbs. When they failed to produce any promising results, Tu referred to the ancient books of traditional Chinese medicine again. Inspired by an over 1,600-
year-old text about preparing qinghao extract with cold water, Tu redesigned the experiments and tried extracting the herb at a low temperature in order not to damage its effective part. On 4 October 1971, after 190 failures, she succeeded in making qinghao extract that could treat malaria in mice.
However, it was hard to produce enough qinghao extract for large trials because research resources were limited. Tu and her team managed to find solutions to the problem. When there was no research equipment, they had to extract herbs using household water containers. They worked day and night and their health began to suffer because of the poor conditions, but they never gave up.
Even with large amounts of qinghao extract produced, however, they still faced another problem. The trials on patients were likely to be postponed because they did not have sufficient safety data. To speed up the process and ensure its safety, Tu and her team volunteered to test qinghao extract on themselves first.
The efforts of Tu and her team finally paid off. In November 1972, through trial and error, they successfully discovered qinghaosu—the most effective part of the qinghao extract. As a key part of many malaria medicines, qinghaosu has since benefited about 200 million malaria patients. More than 40 years after its discovery, Tu was eventually awarded a Nobel Prize for her work. In her Nobel Lecture, she encouraged scientists to further explore the treasure house of traditional Chinese medicine and raise it to a higher level. Perhaps the next generation of scientists, drawing on the wisdom of traditional Chinese medicine, will indeed discover more medicines beneficial to global health care.
