为了更好地掌握这些万能句型，让我们来进行一次实战演练。假设我们有一个图表，显示了2010年至2020年间某城市的就业率和失业率。

**第一段：概述图表**
"The chart illustrates the employment and unemployment rates in a city from 2010 to 2020."

**第二段：描述动态趋势**
"From the chart, it is evident that the employment rate increased steadily from 70% in 2010 to 85% in 2020. Conversely, the unemployment rate showed a marked downward trend, declining from 12% to 5% over the same period. The data for both rates fluctuated slightly during the middle years but overall followed a clear trend."

**第三段：进行数据对比**
"Compared to 2010, the employment rate in 2020 is significantly higher, showing a rise of 15 percentage points. On the other hand, the unemployment rate in 2020 is notably lower, decreasing by 7 percentage points. This stark contrast highlights the city's improvement in job market conditions over the decade. Among the years, 2016 stands out with a slight dip in employment and a corresponding rise in unemployment, which is an exception to the overall trend."
