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 7.0)

The diagram illustrates the production steps involved in producing sugar from sugar cane. The manufacturing process consists of seven sequential steps to produce sugar.

Overall, the method begins by growing and harvesting the sugar canes. These are crushed into juice and further purified using a filter. In the next step, an evaporator is used to make syrup, which then undergoes through a process of centrifugation. The separated sugar is dried and cooled in the last step.

Initially, sugar canes take 12-18 months to grow. Once these are grown, they are harvested. The harvested sugar canes are then crushed with an equipment to make juice. This juice is filtered through a limestone filter in order to purify it.

Once juice is purified, it further goes for processing in an evaporator. As the heat is applied, the water content from juice is evaporated and juice becomes more dense and eventually produce syrup. To separate sugar crystals from syrup centrifugation is used. In the penultimate step, these sugar crystals are dried and further cooled in the end.

Task Achievement / Task Response: Band 7.0

The response gives a clear account of the process and includes its main stages in the correct order, from growing the cane for 12–18 months to drying and cooling the sugar. The overview also identifies the key transformations—crushing to obtain juice, purification, evaporation into syrup, and centrifugation. This covers the task well. Some details, however, go beyond what the diagram states: it does not specify that water is evaporated or that the juice becomes “more dense,” and the final stage is described as drying and cooling the crystals without explicitly identifying the output as sugar. To strengthen the report, keep explanations closely tied to the visual and mention that harvesting can be done mechanically or by hand.

Coherence and Cohesion: Band 7.0

The information is organised clearly: an introduction is followed by an overview and then two paragraphs tracing the stages in sequence. Transitions such as “Initially,” “Once,” and “In the penultimate step” help the reader follow the process, and the progression from cultivation to the final product is easy to understand. The paragraphing is appropriate and the stages are grouped sensibly. Some linking is slightly repetitive, particularly the repeated use of “Once,” and “In the next step” in the overview is less precise than a direct description of the sequence. More varied, unobtrusive links and clearer references to the material at each stage would make the flow even smoother.

Lexical Resource: Band 7.0

The response uses a suitable range of process vocabulary, including “purified,” “evaporator,” “syrup,” “centrifugation,” and “crystals.” These choices show awareness of the technical subject and generally communicate the stages precisely. There are occasional awkward collocations or imprecise choices: “crushed with an equipment” is not idiomatic, “undergoes through a process” is redundant, and “further goes for processing” is unnatural. “Produce sugar” is also less precise than describing the crystals as the final product. Aim for concise, natural process language and use the diagram’s labels where they are accurate; this would improve flexibility and precision without changing the clear meaning.

Grammatical Range and Accuracy: Band 7.0

There is a useful mix of simple and complex structures, including the overview sentence beginning “In the next step” and the time clause “Once juice is purified.” Many sentences are accurate and punctuation is controlled, so the sequence remains clear. A few grammatical errors persist. In “crushed with an equipment,” the article and countability are incorrect; “an equipment” should be “equipment” or “a piece of equipment.” In “juice becomes more dense and eventually produce syrup,” the verb should agree with “juice” (“produces”), or the sentence can be recast. “Undergoes through” also combines incompatible patterns. Check agreement and verb complementation when editing, while continuing to use varied sentence forms.
