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 6.5)

The diagram presents different stages of how sugarcane is converted into sugar.

Overall, growing is the first and longest part of this process followed by a number of crucial stages such as crushing, purifying, centrifuging, and drying and cooling of the sugar, marking the last and final phase of this long process.

The process of producing sugar starts from growing sugarcane which is the longest stage of this process as it takes twelve to eighteen months, followed by harvesting which can be done through harvestor machines or human beings. Next, the sugarcane is crushed and purified juice is being made of it, marking it as a decisive phases.

After being evaporated, the centrifuge marks the sixth stage of the process where the sugar crystals are separeted from syrup. The sugar is dryed up and is kept in a large tube for cooling; which is the last and final part of manufacturing sugar from sugarcane.

AI examiner evaluation

Task Achievement / Task Response: Band 7.0

You give a clear account of the process from growing through to drying and cooling, and include the key duration of twelve to eighteen months and both harvesting methods. The overview identifies growing as the longest stage and signals the final stages, while the description of centrifuging correctly explains that crystals are separated from syrup. Some details are less precise: the diagram shows juice passing through a limestone filter before evaporation, but “purified juice is being made of it” does not clearly explain this step. The final product is dried and cooled in a cylinder; saying it is “kept in a large tube” adds a size and storage detail not shown. More exact reporting of each transformation would strengthen an otherwise clear summary.

Coherence and Cohesion: Band 7.0

The response is organised into an introduction, an overview and two chronological detail paragraphs, so the reader can follow the process from cultivation to the finished sugar. Sequencing expressions such as “Overall,” “Next,” and “After being evaporated” help signal progression, and the stages are generally presented in the correct order. Some links between stages are compressed, however: “the sugarcane is crushed and purified juice is being made of it” combines crushing and filtration without clearly showing the transition from cane to juice and then to purification. The overview also repeats “last and final,” which is redundant. Use a few precise links to clarify how each output becomes the input for the next stage.

Lexical Resource: Band 6.5

You use a suitable range of process vocabulary, including “harvesting,” “crushed,” “evaporated,” “centrifuge,” and “sugar crystals,” and these choices make the subject clear. There is also some attempt at more formal description, such as “crucial stages” and “decisive phases.” However, several expressions are imprecise or unnatural for this diagram: “purified juice is being made of it,” “dryed up,” and “kept in a large tube.” The spelling of “harvestor” and “separeted” also reduces accuracy. The range is adequate and includes relevant technical terms, but more precise collocations and accurate spelling would make the description more flexible and polished.

Grammatical Range and Accuracy: Band 6.0

You use a mix of simple and complex forms, including the overview sentence beginning “Overall” and the clause “which is the longest stage … as it takes twelve to eighteen months.” Most meanings remain understandable, but some grammatical errors recur. In “purified juice is being made of it,” the passive construction is awkward and does not clearly express the process; “the juice is purified” would be more direct. “After being evaporated, the centrifuge marks the sixth stage” has an unclear opening modifier, since the juice, not the centrifuge, is evaporated. The final sentence also uses a semicolon before “which,” where a full stop or conjunction would be more appropriate. Aim for clearer passive forms and check clause attachment and punctuation.
