Let's look at an introduction and overview for the line graph below.
The graph below shows changes in young adult unemployment rates in England between 1993 and 2012.
Introduction and overview paragraphs:
The line graph compares levels of unemployment among 16 to 24-year-olds with overall unemployment figures over a period of 20 years in England.
It is clear that the proportion of young adults who were unemployed at any time between 1993 and 2012 was significantly higher than the overall proportion of adults without work. Unemployment rates for both groups of adults were consistently higher in London than in the rest of England.
Can you see examples of paraphrasing in my introduction? Can you see which two main points I chose for my overview?
