Given that motivation is so central to our lives, what do we truly understand about how it operates and about its role in our lives? The assumption is that it's driven by a positive, external reward. Do this, get that. But the story is much more complex. One of the most striking aspects of motivation is that it often drives us to achievements that are difficult, challenging and even painful. You may think that you would be happy to spend all your time sitting on a whitesand beach drinking and that as long as you get to fill your days this way, you would be happy forever. But while a few days of enjoyment might be fun from time to time, I can't imagine that you would be satisfied by spending your days, weeks, months, years and even your life this way. Research that examines the differences between meaning and happiness finds that the things that give us a sense of meaning don't necessarily make us happy. Moreover, people who report having meaningful lives are often more interested in doing things for others, while those who focus mostly on doing things for themselves report being only superficially( 表面的 ) happy. The essential quality of “meaning” has to do with having a sense of being involved in something bigger than the self. We all know people obtain a great sense of meaning even in the most unpleasant of circumstances. Many volunteers spend portions of their lives working in dangerous, wartorn areas trying to keep disease and death from innocent civilians or teaching orphans to read. Their pain is real; their sense of doing something truly meaningful is substantial( 丰富的 ). They show how our deeprooted desire to believe that our lives have purpose beyond our lifespan drives us to work extra hard, even to the point of our own personal suffering, in order to gain more meaning. The point is that these seemingly odd and irrational( 不合理的 ) motivations get us to do things that are complex, difficult and unpleasant. But they go beyond helping people in need. They motivate us in every aspect of our lives—whether in our personal relationships, in our individual pursuits or in the workplace. 1. According to the author, which of the following about motivation is TRUE? A. Motivation is simply driven by external rewards. B. Motivation is largely determined by social responsibilities. C. Motivation enables us to gain more financial returns. D. Motivation drives us to struggle for achievements. 2. According to the research, which of the practices gives us a sense of meaning? A. Reading a classic novel in the leisure time. B. Enjoying sunshine and comfort on the beach. C. Accompanying terminal patients in hospital. D. Listening to popular music in the sitting room. 3. The example of people's voluntary work in Para. 4 mainly indicates that ________. A. experiencing personal suffering is a necessary part of our growth B. voluntary work serves the purpose of adding happiness to our lives C. it's our duty to help people in need to get out of their sufferings D. life's great rewards come from our experience of tough circumstances 4. What can we infer from the passage? A. People should make sacrifices for social benefits due to their short lifespan. B. The value and impact of motivation goes beyond our social circle and existence. C. Helping people in need is the most important goal of a human being nowadays. D. Superficially happy people usually put others first rather than focus on themselves.
