How To Plan IELTS Discussion Essays

# 1 Analyse the question

This is an essential step in the planning process and will ensure that you answer the question fully. It’s quick and easy to do. You just need to identify 3 different types of words:
1. Topic words
2. Other keywords
3. Instruction words
We’ve already considered the instruction words (the actual question) so we’ll focus on the first two.
Topics words are the ones that identify the general subject of the question.
Some people think that zoos are cruel and should be closed down. Others, however, believe that zoos can be useful in protecting wild animals.

Many people do this first step of the process and then write about the topic in general. This is a serious mistake and leads to low marks for task achievement.
What we need to do now that we know the general topic, is to understand exactly what aspect of zoos we're being asked to write about.

The other keywords in the question tell you the specific topic you must write about. They define the opinions stated in the statement.
