Reading can also be good preparation for the writing test. Just search online for a writing task 2 topic, and read some newspaper articles about it.
For example, last week we looked at the topic of "high salaries" in writing task 2. So let's see if we can find something to read about this topic.
Click here to see a newspaper article that I found when I put the phrase "maximum wage" into Google. It's full of great vocabulary for the high salaries topic (e.g. grossly-inflated pay, inequality in the workplace, pay gap), and you might find it interesting that British politicians are debating this issue.
