IELTS Writing Task 1 question

The diagram below shows the manufacturing process for making sugar from sugar cane.

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

How sugar is produced from sugar cane

Student answer (Band 6.0)

The provided diagram represents the production process of sugar from sugar cane. Overall, the sugar is produced from sugar cane in seven stages which include sugar cane growth, harvesting, crushing, filtration, evaporation, crystal separation, drying and cooling processes.

The sugar cane takes 12-18 months to achieve its proper growth and then it is harvested by farmers and harvesting machines. In the next step, sugar cane is crushed until its juice is produced, and then it is passed through a filtration process. Juice is filtered out by using limestone filter which purifies the juice, and then it is brought into an evaporator and beneath the evaporator there are fire flames where juice is converted into a liquid syrup. A centrifuge is placed which separates out sugar crystals from heated syrup. In the last step, the crystals are dried and then cooled down to room temperature which leads to the formation of edible sugar.

Task Achievement / Task Response — Band 6.0

The response covers all stages of the sugar production process, from growth to the final product. You have successfully identified the main features and provided a clear overview. However, the description could be improved by making more explicit comparisons or highlighting the transformation between states (e.g., solid to liquid to solid). While you mention the stages, the explanation of the 'centrifuge' and 'evaporator' is slightly descriptive rather than analytical. To reach a higher band, ensure you focus on the flow of the process and the key changes at each transition point rather than just listing the steps.

Coherence and Cohesion — Band 6.5

The essay is logically organized, moving chronologically through the seven stages of production. Paragraphing is used to separate the introduction/overview from the detailed process description. Cohesive devices such as 'In the next step', 'then', and 'In the last step' are used to guide the reader. However, the transition between the filtration and evaporation stages is slightly repetitive with the use of 'then' and 'and then'. Using a wider variety of linking phrases or relative clauses would improve the flow and make the progression feel less mechanical.

Lexical Resource — Band 6.0

You have used a good range of vocabulary relevant to the topic, such as 'harvesting', 'filtration', 'evaporator', and 'centrifuge'. These terms are used accurately. However, there is some repetition of basic verbs like 'produced' and 'filtered'. To improve, try to incorporate more precise academic vocabulary to describe the physical changes, such as 'extracted', 'purified', or 'crystallized'. The vocabulary is sufficient for the task, but lacks the sophistication and flexibility required for a higher band score.

Grammatical Range and Accuracy — Band 6.0

The response demonstrates a mix of simple and complex sentence structures. Most sentences are clear and error-free, which ensures that communication is never impeded. There are some minor issues with article usage, such as 'A centrifuge is placed' (should be 'A centrifuge is used') and 'beneath the evaporator there are fire flames' (which is slightly awkward phrasing). While you have used passive voice appropriately for a process description, increasing the variety of complex sentence structures would demonstrate a wider grammatical range.
