IELTS Academic Writing Task 1 with model answer

You should spend about 20 minutes on this task.

Eating sweet foods produces acid in the mouth, which can cause tooth decay. (High acid levels are measured by low pH values)

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

Write at least 150 Words.

Model Answer:

The given line graph illustrates the effect of two different types of sugar as well as honey on  tooth.

According to the graph, the two types of sugar (fruit and cane) and honey commence acidic activity in the mouth soon after they are eaten; however, such acid levels remain safe for about 3 minutes after which the effect of each type of sugar and honey becomes differentiated. It is clearly seen that cane sugar is in the harmful type as it increases mouth acidity to the highest level of PH3.5 just after 5 minutes. The acidity level then steadily declines over the following 25 minutes before it finally reaches the safe zone of PH 3.5. On the other hand, fruit sugar and honey exhibited a milder form of interaction  in the mouth with acid levels reaching a little less than PH5 and 4.5 at 5 minutes for honey and fruit sugar respectively. The acid levels of fruit sugar and honey are the same 9 minutes after consumption, recording a PH of 4.8. After that acid levels caused by honey quickly returns to the safe zone of PH 5.5 at approximately 14 minutes. Whereas acid levels cased by fruit sugar return to safe PH level after 20 minutes.
