How to Write a Report?

For any report writing or for writing an IELTS Task-1, the identification of an illustration is very important. So the first step is:-

1. Analyse the illustration

For starting the report, first of all, analyze the picture. As aforementioned, there are seven types of illustrations. So, identify the type. It will lead you towards another step of planning.

2. Planning

Planning takes two to three minutes for a report. Plan what to write an introduction, body paragraphs, and conclusion. Basically, planning is done to recognize the key features of the illustration. Once you identify the key features, you will be halfway through the report. Always remember that writing should be qualitative, not quantitative. So always focus on writing the key features and not the whole of the figures.

What can be the key features?

  • It can be any maximum or major figure.
  • It can be the lowest figure among the majors.
  • It can be any inclining or declining trend in time.
  • It can be about one year or one country only focusing on one variable.

3. Writing an Introduction

Introduction are the opening lines of the task. It should be effective. Introduction of task one is basically the rephrase of the given introduction in the task itself. Start with the name of the illustration, writing about what it shows, ending it with the time or the name of the place.

Start writing the paragraphs with the key features and in the first paragraph, important features should be highlighted. However, in the second paragraph, other trends or other features can be written.
