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 process diagram illustrates the process of manufacturing sugar from sugar cane.

Overall, the whole procedure requires seven major steps, starting from plantation of sugar canes and ending with drying and cooling of sugar granules.

First of all, the sugar cane plants are grown in a field, which takes around 12 to 18 months to fully mature sugar canes. After that, the harvesting process starts, either by mechanically with the help of machinery or physically by the farmer, to cut down the sugar cane from the field. Once the cutting have been done, a roller machine is used to extract the juice from sugar canes by crushing it.

In the next step, the process of purification of the juice is taking place with a limestone filter. Next, the heating process starts in which the juice becomes a thick syrup after the evaporation ends. Following by centrifugation, that separates the sugar crystals from the syrup and finally the last step which includes; drying and cooling of sugar, before making it available for consumers.

AI examiner evaluation

Task Achievement / Task Response: Band 7.0

You give a clear account of the process, including its seven stages, the 12–18-month growing period, both harvesting methods, and the transformation from cane to juice, syrup, crystals and finally sugar. The overview correctly identifies the beginning and end, while the body follows the main sequence and explains the key operations. This covers the task well. To make the account more fully developed, describe the centrifuge’s role explicitly as separating the crystals from the remaining syrup, and avoid adding unsupported details such as the sugar being “available for consumers.” The process is otherwise accurately represented, with no major stage omitted.

Coherence and Cohesion: Band 7.0

The response is organised into an introduction, a concise overview and a body that follows the process in order. Sequencing phrases such as “After that,” “Once,” “In the next step” and “finally” help the reader track the stages, and the progression is clear throughout. Some linking is slightly mechanical because several transitions simply announce the next step. The final sentence also combines centrifugation and the last stage in a long construction, making the relationship between them less smooth. Use a separate sentence for drying and cooling, and vary transitions with references such as “The resulting syrup” or “The separated crystals” to make cohesion more flexible.

Lexical Resource: Band 7.0

You use a suitable range of process vocabulary, including “extract,” “crushing,” “purification,” “evaporation” and “centrifugation,” and most choices communicate the stages clearly. There is some awareness of technical language, particularly in describing the separation of sugar crystals from syrup. A few expressions are less natural or precise: “plantation of sugar canes” is awkward for the growing stage, “physically by the farmer” is not the clearest contrast with mechanical harvesting, and “sugar granules” is more specific than the diagram’s label “sugar.” Prefer standard process collocations such as “sugar cane is cultivated,” “harvested by hand,” and “the finished sugar is dried and cooled.”

Grammatical Range and Accuracy: Band 6.0

You use a mix of simple and complex forms, including time clauses (“which takes around 12 to 18 months”) and participle structures (“by crushing it”), and the meaning remains clear. However, some grammatical errors prevent consistently accurate control. For example, “either by mechanically” has an incorrect adverbial form, “the cutting have been done” has subject–verb disagreement, and “Following by centrifugation” is not a well-formed construction. The final sentence is also a fragment after “and finally,” while the semicolon before “drying and cooling” is unnecessary. Aim to make each stage a complete sentence and check agreement and clause structure; for instance, “Once cutting is complete, the cane is crushed.”
