【正确答案】正确答案： Science and technology advances are an important hallmark of social progress. The United Kingdom hosted the first World Expo in 1851, just because it was the first country to launch the Industrial Revolution, thus manufacturing a large number of technological products. The industrial revolution spurred an imposing growth in productivity. The productivity generated in less than 100 years after the Industrial Revolution exceeded the total sum of productivity of all previous times. And the last 100 years have seen even greater increases of productivity than the 100 years following the Industrial Revolution. Expo 2010 Shanghai has shown mankind's latest achievements in science and technology such as the new generation of mobile communications, artificial intelligence, new materials and eco-friendly construction, which speak volumes about the immense human wisdom and creativity.
