This lesson is based on task 1 of the Academic IELTS Writing exam, in which you write a report about some data. There is a model answer and six exercises, practising various common writing errors. You must complete each exercise before moving on to the next.
Task type: bar chart and line graph
Key skills: eliminating persistent basic grammatical errors
You should spend about 20 minutes on this task.
The figures below show how much energy (measured in kilowatt hours) the average UK house and apartment used in different months of the year and the average monthly temperature across the same period.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
Write at least 150 words.
The bar chart and line graph provide information about the amount of energy that is used at different times of the year by two types of households (i.e. houses and apartments) in the UK, as well as the average outside temperature in each month. Overall, it is evident that more energy is consumed by those who live in houses than people in apartments throughout the year, and that energy usage is at its highest in the winter months when temperatures are the lowest, for both kinds of dwellings.
The average energy consumption for a house is between 575 kilowatt hours (in the spring and autumn months when temperatures are between 10 and 15 degrees Celsius) and about 800 kilowatt hours (in December and January when the weather is at its coldest, i.e. 3 to 4 Celsius) per month. The months of June (17 C; roughly 630 kWh) and August (19 C; 650 kWh) were the only slight variations from the otherwise steady trend of more energy use in colder weather. The trend is virtually exactly the same for the amount of energy consumed by those living in apartments. The only difference is that energy use in apartments is approximately 50 kWh lower (e.g. 750 kWh in December) than in houses every month.
