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 8.0)

The diagram illustrates the sequential stages involved in the commercial manufacturing of sugar from sugar cane. Overall, the process consists of seven distinct phases, beginning with agricultural cultivation and culminating in the drying and cooling of the final product.

Initially, sugar cane requires an extensive growth period of approximately 12 to 18 months before it is ready for harvesting. Once harvested, either manually or via mechanical trackers, the cane stalks are fed into industrial crushing rollers to extract the raw liquid juice.

Following this extraction phase, the raw juice is passed through a limestone filter to remove unwanted impurities. The purified liquid is subsequently transferred into an evaporator, where it is heated until the water boils away, transforming the juice into a concentrated, thick syrup.

During the this stage, this syrup is processed inside a centrifuge machine. The high-speed spinning motion successfully separates the solid sugar crystals from the liquid byproduct. Finally, these wet crystals are sent to a drying and cooling chamber, yielding the refined sugar ready for consumption.

Task Achievement / Task Response — Band 7.5

The response clearly identifies the main stages of the sugar production process. You have successfully highlighted the key steps from cultivation to the final refined product. The overview provided in the introduction is effective, and the progression through the seven phases is logical. To reach a higher band, ensure you explicitly mention the input and output at each stage (e.g., the role of limestone or the specific byproduct of the centrifuge). While you have described the process well, adding a brief concluding summary or a more detailed comparison of the mechanical versus manual harvesting would further enhance the depth of your analysis.

Coherence and Cohesion — Band 8.0

The essay is well-organised with a clear, logical progression from the beginning of the process to the end. Paragraphing is used effectively to separate the different stages of production. You have employed a range of cohesive devices such as 'Initially', 'Following this extraction phase', 'subsequently', and 'Finally', which help the reader follow the sequence of events smoothly. The referencing is generally clear, and the flow of information is natural. The text is easy to read and demonstrates a high level of coherence throughout.

Lexical Resource — Band 7.5

You have used a good range of vocabulary appropriate for a process description, such as 'sequential stages', 'commercial manufacturing', 'impurities', and 'byproduct'. The terminology is precise and fits the context of the task well. There are no significant errors in word choice or collocation. To push towards a higher band, you could incorporate slightly more sophisticated or academic collocations, such as 'subjected to' instead of 'passed through' or 'facilitating the separation' instead of 'successfully separates'. Overall, the lexical range is sufficient and used with good control.

Grammatical Range and Accuracy — Band 8.0

The writing demonstrates a good command of complex sentence structures, such as the use of participial phrases ('beginning with...', 'transforming the juice into...') and passive voice constructions, which are essential for process descriptions. The grammar is generally accurate, with only a minor slip in the phrase 'During the this stage', which is a simple repetition error. The majority of your sentences are error-free, and your punctuation is handled correctly. The variety of structures used contributes to a fluent and professional tone throughout the report.
