Synthesis 综合 combines sources through agreement, difference, qualification or a gap to
develop your argument. Sources must remain identifiable. Several sentences with separate
citations can synthesise; one sentence with many citations can still be unsupported. Organise
around the question or idea and explain how the sources relate.
Supplied fictional practice source pack
These extracts and references are written for teaching, not actual published studies. Use them
only in this exercise; do not present them as real research.
Li (2020), Shade at street sites, practice source A. “At the sites observed, shaded pavement
had lower midday surface temperatures than nearby unshaded pavement.”
Chen (2021), A second set of shaded sites, practice source B. “At a different set of sites,
shaded pavement also had lower midday surface temperatures. We did not measure whole-city
average air temperature.”
Wang (2022), Water for planted trees, practice source C. “Some planted trees needed summer
irrigation. We did not measure the total water cost or compare it with the cooling benefit.”
Worked synthesis. “Both illustrative reports describe lower midday surface temperatures at
shaded sites (Li, 2020; Chen, 2021). Wang (2022) adds an irrigation requirement for some planted
trees. Together they suggest that a planting proposal should consider cooling and water needs;
these extracts do not establish a whole-city temperature change or an affordable water cost.”
The relationship is agreement plus a practical qualification. Citations remain traceable.
Keep the distinction between surface temperature and air temperature. Do not add “exactly when
cooling matters most” or a measured city-wide effect absent from the extracts.
Practice. Write two or three sentences comparing the cooling evidence with the water issue.
