In Thursday's lesson I suggested that you should avoid using words like soar, rocket and plummet when describing changes on a graph or chart. I explained that these words exaggerate too much, and that they are not 'academic'.
But someone asked this sensible question:
How can we get a high score for lexical resource (vocabulary) if we only use common words like 'increase', 'rise' and 'fall'?
The quick answer is that it's better to use 'less common vocabulary' for other aspects of your description. If you analyse this band 9 essay, you'll see that I used common words like rose, decreased, reaching and dropped to describe changes, but I managed to use 'less common vocabulary' for other aspects of my description e.g. global turnover, devices, namely, platform.
I'll explain more about how to get a high vocabulary score tomorrow.
