Why did Zhong Yang want more people to do seed collection and research? From the article, we know that seed banks need many different kinds of seeds to protect important plants from disappearing forever. The work of seed collection and research is very hard, and it involves a huge amount of work. Also, he knew that important scientific work could be done better with more people involved. He wanted to train local students to become scientists so that the research could continue, and more seeds and plant information could be collected for China and the world. 2. What made Zhong Yang admirable? What can we learn from him? What made him admirable: He dedicated his whole life to researching plants and seeds, collecting many important seeds for China’s seed banks to protect plant diversity. He overcame great difficulties (cold weather, high altitudes, illness) to collect seeds in Xizang, showing strong perseverance and dedication. He trained local students to continue the work, passing on his spirit and knowledge, which means his legacy lives on beyond his own life. What we can learn from him: We should have a strong love and curiosity for our chosen field, and stick to our goals even when facing hardships. We should be willing to make contributions to society and the world, not just for personal gain. We should value passing on knowledge and spirit to younger generations, so that good work can continue for a long time. ... Think and Share What do you think seed banks mean for the future?
