【正确答案】 Science is based on facts. Science means honest and solid knowledge. It does not allow the slightest falsity and requires tremendous hard work. Meanwhile, science also needs creativity and imagination to break the restraint of traditional rules and to promote its development. Ladies and gentlemen, please do not allow poets to monopolize the fantasy. Via science, many fantasies in ancient China have come true, including the Goddess Chang's fly to the moon (with the elixir of life, chased by her famous archer-husband); the underwater treasure search in the Dragon King's palace; and those described in a famous Chinese book Creation of the Gods. The great astronomer Copernicus said that it is man's duty to be courageous enough to seek for truth. Chinese people have always been bold in exploration, creation and revolution through all the ages. We must break through conventions, blaze new ways by overcoming difficulties so as to achieve the scientific development. The combination of whimsicality and practicality is the unique characteristic of scientists. So let us explore the boundless universe in quest of never-ending truth.
