雅思口语P2 Describe a person who knows a lot（文字版）

I've met many smart people in my life. Today, I'm going to talk about one in particular. His name is David. Originally, he is from a small part of Thailand, but his family moved to China 5 years ago. So, now, he lives in Shanghai with his parents. David works as a car designer in BMW, a renowned automobile company. He is appointed in the head office in Shanghai. He completed his Bachelor of Technology in Mechanical Engineering from the University of Shanghai. I feel that he is one of the smartest men I have ever seen. Despite being a fresh graduate, he was offered a place in a world-class organization. Many senior people struggle for years to join such companies. He made it in the first year of his career. That is definitely a remarkable achievement. This was made possible because he knows so much about various subjects, I love discussing with him because he always has an answer to my questions, and even if he doesn't, he knows what to do to get the answer. Another reason why I think he is brilliant is that he is an active learner. Normally, when anyone starts working, they don't like improving their knowledge or skills. But, this is not the case with him. He is always willing to expand his knowledge and general culture. He often reads periodicals and attends seminars to keep himself updated with the latest information. All these things make him different from others. I can't help but admire him. He is a role model for me.
