Air
pollution releases pollutants
due to
human development and other natural or anthropogenic activities into the atmosphere.
Air
Quality
Index (AQI) is an index that quantitatively describes
air
quality
to report hourly or daily
air
quality
of a region. The level of
air
quality
affects people's life and health. There are many ways to reduce
air
pollution, one of them is rain. As a raindrop falls through the atmosphere, it can wash any pollutants
such
as PM, SO2, NO2, O3, CO, etc.
This
process is coagulation, a natural phenomenon that can clear
air
in the sky. Research conducted in Suzhou, China showed that 7 out of 9 points studied experienced a decrease in pollutant content as seen from the AQI value
due to
rain in the region.
This
research showed that rain is effective in washing away pollutants in the atmosphere.

Include an introduction and conclusion

A conclusion is essential for IELTS writing task 2. It is more important than most people realise. You will be penalised for missing a conclusion in your IELTS essay.

The easiest paragraph to write in an essay is the conclusion paragraph. This is because the paragraph mostly contains information that has already been presented in the essay – it is just the repetition of some information written in the introduction paragraph and supporting paragraphs.

The conclusion paragraph only has 3 sentences:

  • Summary
  • Restatement of thesis
  • Prediction or recommendation

Example:

To summarize, a robotic teacher does not have the necessary disciple to properly give instructions to students and actually works to retard the ability of a student to comprehend new lessons. Therefore, it is clear that the idea of running a classroom completely by a machine cannot be supported. After thorough analysis on this subject, it is predicted that the adverse effects of the debate over technology-driven teaching will always be greater than the positive effects, and because of this, classroom teachers will never be substituted for technology.

Start your conclusion with a linking phrase. Here are some examples:

  • In conclusion
  • To conclude
  • To summarize
  • Finally
  • In a nutshell
  • In general
