silence should be gold, because it can make us more rational and modest. silence let us have more opportunities to think about some matters. then the decision will be made more carefully. as a result, we may deal with something more smoothly, and finally achieve the success. so in my opinion, i think silence is a kind of reflection. you know reflection is a symbol of wisdom. in the south of our school's yifu library, there is a contemplator statue sitting in the square. he has sited and kept silent there for many years. i think this statue teach us how to consider and reflect. that's to be modest and silent, when thinking. it will be a valuable venture for all researchers and students. so it is necessary to study how to keep silent.

someone may realize that silence is rather easier than speech. i think it is not exactly true. speech only needs our courage and confidence. however, silence not only needs our courage, but also need us to have clear mind and generous heart. sometimes it's not easy to get this. for example, do you remember in the world cup final 2008, zidan (the captain of french team) head-butt a player of italy so that he was showed red card and sent off immediately. it is pity for french, because of losing the leader in the football field. finally, french team lost the opportunity of achieving final success. so silence make person calm, and avoid impulsion.

sometimes silence means endurance. though i admit endurance isn't good for our psychology health, sometimes it is necessary. if you want to success, you have to be willing to endure something which may be produced by yourself or others. then just keep silent to do it. you should believe that action speaks louder than words. so do a man of action(doer).
