【正确答案】 This chart gives us an overall picture of the total number of Chinese tourist traveling overseas from 2008 to 2012. Besides, it also predicts the number of Chinese tourist traveling overseas in 2020, which is about 25, 000. We can see from the chart that the total number is always in increase ：on the whole the increase rate is quite steady from 2008 to 2012 ； the total number in 2012, which is 8, 318, is about two times as much as the total number in 2008 ； while the chart shows almost a threefold increase in the total number from 2012 to 2020. Seeing from the chart, we could get the conclusion that people’s economic conditions have been largely improved.
