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 diaram provides information about the steps of how sugar is manufactured from sugar cane.

Overall, a farmer grows and harvests sugar canes and then goes through several important steps to produce sugar such as crushing, purifying, evaporating, separating, drying and cooling.

Firstly, the sugar canes are grown within 12 to 18 months and then a farmer harvests them by hands or by using a tractor in the second step. The juice is obtained in the third step after crushing the canes in the machine.

The fourth step is to purify the juice through limestone filter. The juice in the next step is converted into syrup by heating the liquid in the evaporator. Then in the sixth step sugar crystals are separated from syrup via centrifuge. In the last step, the sugar crystals are dried and cooled in a container and this is how the sugar is manufactured with bamboo sticks.

Task Achievement / Task Response: Band 6.0

The response covers the main stages in the correct order, including the 12–18-month growing period, the two harvesting methods, crushing, purification, evaporation, centrifuging, and drying and cooling. The overview also identifies the process as a sequence from cane to sugar. However, some details are unclear or inaccurate: “this is how the sugar is manufactured with bamboo sticks” introduces an unsupported item, while the final stage is described as occurring “in a container” rather than clearly reporting drying and cooling. The account also gives limited detail about the limestone filter and the separation of crystals from syrup. More precise reporting of these features, and removal of the invented bamboo-stick claim, would make the summary more complete.

Coherence and Cohesion: Band 6.0

The response is arranged in a clear sequence, with an opening, an overall summary, and a body that follows the numbered stages from growing to final processing. Sequencing expressions such as “Firstly,” “The fourth step,” “Then,” and “In the last step” help the reader follow the process. However, the repeated step-by-step framing makes cohesion somewhat mechanical, and the final sentence is confusing because “and this is how” joins the process description to an unsupported claim about bamboo sticks. The overview could also be separated more clearly from the detailed stages, and transitions between stages could be made more natural. Overall, the organisation is coherent, though some linking and referencing are not fully controlled.

Lexical Resource: Band 6.0

The response uses an adequate range of process vocabulary, including “crushing,” “purify,” “evaporator,” “syrup,” and “centrifuge,” which allows the stages to be identified. Some less common terms are used, but there are inaccuracies in word choice and collocation: “by hands” is not the natural expression, “through limestone filter” needs a more precise phrasing, and “manufactured with bamboo sticks” is both unsupported and unsuitable here. “Diaram” is also a spelling error, and “sugar canes” is less natural than “sugar cane” when referring to the crop generally. Use accurate process terminology consistently and avoid adding objects not shown in the diagram.

Grammatical Range and Accuracy: Band 5.5

There is a mix of simple and more developed sentence forms, and most of the process remains understandable. For example, the sentence beginning “The juice in the next step is converted into syrup” uses a passive structure appropriate for describing a process. Some grammatical errors remain, however. “A farmer grows and harvests sugar canes and then goes through” has an unclear subject, since the process—not the farmer—continues through the later stages. “By hands” and “through limestone filter” also show problems with article or preposition patterns. The final sentence combines several ideas awkwardly, making the relationship between drying, cooling, and the claimed bamboo sticks unclear. More consistent passive constructions and careful checking of articles and sentence boundaries would improve accuracy.
