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 process diagram illustrates how sugar is made from sugar canes.

This linear procedure consists of seven steps. It starts from the growing of sugar canes which take about 12-18 months and ends at drying and cooling of sugar crystals separated from syrup.

Initially, sugar canes take almost 12-18 months to fully grow. Harvesting of these fully grown sugar canes are done by two different methods. One by the harvester machine and secondly by the farmer himself. Further, those sugar canes are passed through a crushing machine to extract the juice.

Sugar cane juice is purified as it is passed through funnel having a limestone filter. In processing phase, purified juice is heated in an evaporator till it becomes thick and converts into syrup. Afterwards, syrup is rotated in a centrifuge machine which separates the sugar crystals from the syurp. Lastly, separated sugar crystals are left for drying and cooling in a drum.

Task Achievement / Task Response — Band 6.0

The response successfully covers all the main stages of the sugar manufacturing process, starting from the cultivation of sugar cane and finishing with the drying and cooling of the crystals. Key features such as the 12-18 month growing period, the two harvesting methods, juice extraction, filtration, evaporation, centrifugation, and final drying are all reported accurately. The overview statement effectively summarises the process length and main start-and-end points. While comparisons between the two harvesting methods are touched upon briefly, the response could have been slightly more detailed regarding the transformation of the syrup into crystals. Overall, all parts of the prompt are addressed adequately, demonstrating a clear understanding of the diagram without major omissions.

Coherence and Cohesion — Band 6.5

The response is coherent and shows a logical overall arrangement following the chronological order of the process diagram. Paragraphing is used appropriately to separate the introduction, general overview, and body steps. Cohesive devices are employed to guide the reader through the stages, using sequencing words such as 'Initially', 'Further', 'In processing phase', 'Afterwards', and 'Lastly'. However, referencing and cohesion occasionally feel slightly mechanical, and there are minor instances where article usage or transitional phrasing could be smoother. Despite these minor flaws, there is a clear progression from the beginning to the end of the manufacturing process.

Lexical Resource — Band 6.0

The vocabulary used is generally adequate for the task, successfully incorporating process-specific terms such as 'crushing machine', 'limestone filter', 'evaporator', 'centrifuge machine', and 'sugar crystals'. There are some successful attempts at less common lexical items, though occasional inaccuracies in word choice and spelling occur, such as misspelling 'syrup' as 'syurp' in the final paragraph. Phrasing like 'Harvesting of these fully grown sugar canes are done' reveals slight awkwardness in collocation and agreement. Nevertheless, the range of vocabulary is sufficient to convey the process clearly without impeding communication.

Grammatical Range and Accuracy — Band 6.0

The writer employs a mix of simple and complex sentence forms, demonstrating some control over grammatical structures. Examples of passive voice, which are essential for process descriptions, are used correctly in sentences like 'sugar canes are passed through a crushing machine'. However, there are notable grammatical errors, particularly subject-verb agreement issues, such as 'Harvesting of these fully grown sugar canes are done' (instead of 'is done') and missing articles, as in 'passed through funnel'. Punctuation is generally acceptable, and while these frequent minor errors persist, they rarely impede the overall communication of the process steps.
