3. 口语部分
Task:
Describe a tradition in your culture that is unique and explain why it is important to you. Please include specific details in your response.
Sample Answer:
In my culture, one unique tradition is the Dragon Boat Festival, which is celebrated during the fifth month of the lunar calendar. This tradition is important to me because it commemorates the life and death of the ancient Chinese poet Qu Yuan. The festival involves racing dragon boats, which are long, narrow, and paddled by teams of people. It's a symbol of unity and strength, as everyone works together to propel the boat forward. The Dragon Boat Festival also includes eating zongzi, which are sticky rice dumplings wrapped in bamboo leaves. This tradition is a way for us to remember our history and honor the contributions of Qu Yuan, while also enjoying a day of community and competition.

Task:
Do you agree or disagree with the following statement? "All scientific discoveries should be shared among scientists all around the world; governments should not keep these discoveries secret." Use specific reasons and examples to support your answer.
Sample Answer:
I agree with the statement that all scientific discoveries should be shared among scientists worldwide, and governments should not keep these discoveries secret. Firstly, sharing scientific knowledge promotes collaboration and innovation. When researchers from different countries can access the latest findings, they can build upon each other's work, leading to more rapid advancements in various fields. For example, the Human Genome Project was a global effort that involved scientists from multiple countries, and it resulted in a better understanding of human genetics.
Secondly, keeping scientific discoveries secret can hinder the progress of medicine and technology. If a government withholds information about a new medical treatment, it could delay the treatment's availability to patients who need it. This was seen during the COVID-19 pandemic, where the rapid sharing of research on the virus and potential vaccines allowed for a quicker global response.
Lastly, transparency in science fosters trust among nations. When countries openly share their scientific achievements, it can lead to increased cooperation and reduced tensions. This openness can also help to prevent the misuse of scientific discoveries for harmful purposes, as the international community can monitor and discuss the implications of new technologies.
In conclusion, sharing scientific discoveries is crucial for the advancement of knowledge, the well-being of humanity, and global cooperation. Governments should prioritize the dissemination of scientific knowledge to foster a more collaborative and transparent scientific community.。
