　　Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English. You should write your answer on Answer Sheet 2.

　　計量，古稱度量衡，是實現(xiàn)單位制統(tǒng)一，保證量值準確可靠的活動，是現(xiàn)代國家經(jīng)濟、科技、社會發(fā)展的重要基礎。計量歷史悠久，關系國計民生。公元前221年秦朝建立，秦始皇統(tǒng)一度量衡，成為中國古代統(tǒng)一計量制度的里程碑。1875年5月20日《米制公約》的簽署，開辟了全球范圍內推行國際單位制的近代計量新紀元。以量子物理為基礎的現(xiàn)代計量科學技術的研究與應用，為人類文明發(fā)展提供了更加精準的現(xiàn)代計量技術保障。1999年第21屆國際計量大會決定：自2000年起，每年5月20日為“世界計量日”。2015年世界計量日的中國宣傳主題與國際主題一致，為“計量與光”。
