The people who write the questions for IELTS reading do something like this:
- They take a reading passage.
- They read through the passage and stop when they find something interesting.
- They make a question about that part of the passage, usually by paraphrasing it. For example, if the passage contains the phrase "elderly people", the question writer might create a question with the words "senior citizens".
Have you ever tried writing your own IELTS reading question? It's a good exercise to get you thinking like the question writer, and hopefully you'll see why the keyword technique is so useful.
Tip: If you try this, start by writing your own 'true, false, not given' questions.
