6. The graph below shows the number of books read by men
and women at Burnaby Public Library from 2011 to 2014.
Summaries the information by selecting and reporting the
main features, and make comparisons where relevant.
7. PARAPHRASING THE FIRST SENTENCE:
The graph gives information about Burnaby
Public Library between 2011 and 2014. It
shows how many library books people read
over this four-year period.
8. OVERVIEW
As can be seen from the graph, there were different trends for men and women.
The number of books read by men increased steadily between 2011 and 2012,
from about 3000 to 4000. After that, the number rose dramatically to 14000 books
in 2014. This was the highest figure in the period.
Women started off reading more books than men, but their numbers followed a
different pattern. Between 2011 and 2012, there was an increase of 3000 from
5000 books to 8000 books, and then a gradual rise to 10000 books in 2013.
However, in 2014, their numbers fell back to 8000 again.
Overall, there was a strong upward trend in the number of books read by men.
Although women read more books than men in 2011, their reading fell to below
the level of men in 2014.

15. MODEL ANSWER
The line graph shows growth in the consumption of renewable energy during the period
1949-2008 in the USA. The results are also broken down by source.
The first thing to note is that renewable energy use more than doubled over the period,
with particularly strong growth in biofuels. This sector did not exist in 1980 but
experienced a steep rise during the 2000s to over one quadrillion Btu per year. This made
biofuels a serious challenger to both wood and hydroelectric power, which both saw only
limited growth overall. The former grew steadily between 1975 and 1985, but then
slipped back to around its original level of 1.8 quadrillion Btu. The latter began the
period at the same level as wood but experienced more substantial growth. However, it
also fell back to around 2 quadrillion Btu, with a particularly sharp drop in the late 1990s.
Finally, wind power emerged late in the period but showed a gradual rise to around 0.5
quadrillion Btu, suggesting that it, along with biofuels, will replace wood and
hydroelectricity as the main sources of renewable every in the future.
