In 2020, sales of all devices will increase.
In IELTS Task 1 writing candidates are often required to make future predictions based on data in graphs, tables, and charts.
This can be an opportunity to display some sophisticated grammar, in particular the future perfect tense!
In a previous post I showed you how to use a phrase beginning by + time expression to build a sentence using past perfect tense. In fact we can take the same approach with other perfect tenses:
In this example we can say:
By 2020, sales of all devices will have increased.
Here I used the structure:
by + future time expression + subject + will + have + V3
We can then add other information in the usual manner using will for prediction:
By 2020, sales of all devices will have increased. Sales of the PS4 will be double sales for the Xbox One, which will in turn be three times sales for the Wii U.
Future perfect is very rarely used by native speakers because there are very few opportunities to use it! This is one of the reasons why future perfect, and indeed the other ‘perfect’ tenses, helps to increase your IELTS score for grammar in both writing and speaking.
Pay careful attention to the structure of future perfect and good luck with your future predictions in IELTS task 1!
