【答案解析】{{B}} Life-long Learning{{/B}} In today's society, life-long learning has become very important for everyone. This is because one needs to renew his knowledge continuously in order to meet the needs of his work and fast development of the society. There are several ways for one to take a life-long learning. One way is to take a part-time education program. It means that one is learning part time while he is working. The program could be at undergraduate level or graduate level. The second way is to study by oneself. You can learn whatever you need for your work on your own. You can learn from books, from TV programs or from Internet or radio. In my opinion, life-long learning is necessary for us. We should choose one of the ways mentioned above, which depends on your own personal preference and interest. I prefer the first one because this kind of learning is systematic and formal. With the help of the teachers, it is easier to learn and quicker to get what you need for your work.
