This week I have spent he same simple grammatical error from two otherwise excellent students. It is highly likely that you will use some form of the verb ‘to grow’ in the IELTS academic writing paper part one when describing a rise in a statistic. It’s an irregular verb, but a common one, and you can’t afford to get it wrong.
The number of tourists grows in every year displayed in the chart.
The numbers grew hugely from 2000 to 2015.
The figures have grown since the start of the millennium.
Also you should ensure that you know the noun from this verb and how to use it.
Last year saw significant growth in the numbers of people flying long haul.
