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 illustrate the manufacturing process of sugar from sugar cane. Overall, the process consist of 2 parts, agricultural and manufactural, with 7 steps in total. The process start from growing the sugar cane to drying and cooling to make the ready-to-use sugar.

There are 2 steps in agricultural part which are growing and harvesting. Sugar canes take about 12-18 months to grow, then it is harvested by a heavy machinery or mannually by a human hand.

After that, manufactural part starts with crushing the sugar canes in a heavy roller to make a juice out of it. Before the juice is transformed into a thick syrup in the evaporator by heating it up, it is purified by the limestone filter. Furtherly, sugar crystals are seperated from the syrup in the centrifuge equipment. Lastly, after the process of drying and cooling the sugar crystals, it become our ready-to-use sugar in daily life.

Task Achievement / Task Response: Band 6.5

You cover the main stages and give a clear overview by dividing the process into agricultural and manufacturing parts, noting seven steps and the 12–18-month growing period. The sequence from harvesting through crushing, purification, evaporation, centrifuging, and drying is generally accurate. This shows good coverage of the task, while some details are less fully reported: for example, the diagram shows two harvesting methods, but “by a heavy machinery or manually by a human hand” is imprecise, and the role of the centrifuge in separating crystals from syrup could be stated more clearly. The final phrase about sugar being ready for daily life adds an unsupported use rather than describing the diagram. More precise reporting of the stages would strengthen the response.

Coherence and Cohesion: Band 6.5

The response is organised into an introduction and overview followed by the agricultural and manufacturing stages, and the process is presented in a mostly logical order. Sequencing expressions such as “After that,” “Before,” “Furtherly,” and “Lastly” help the reader follow the stages. However, the division into “2 parts” is not fully developed as a paragraph structure, and some links feel mechanical or awkward. “Before the juice is transformed…” temporarily reverses the sequence before returning to purification, while “Furtherly” is not a natural transition in this context. The reference in “it is harvested” is understandable but could be clearer by naming the sugar cane. More consistent paragraphing and simpler, more precise transitions would make the progression smoother.

Lexical Resource: Band 6.0

You use a relevant range of process vocabulary, including “evaporator,” “limestone filter,” “syrup,” “centrifuge,” and “drying and cooling,” which allows you to describe the diagram clearly. There are also attempts at more specific wording, such as “agricultural” and “manufacturing.” However, several choices or spellings are inaccurate or unnatural: “manufactural” is not the appropriate form, “heavy roller” is less precise than “crusher,” and “Furtherly” is an unsuitable connector. “Ready-to-use sugar in daily life” is also wordy and not a natural description of the final product. These issues do not prevent understanding, but more accurate collocations and careful spelling would improve precision and control.

Grammatical Range and Accuracy: Band 6.0

You use both simple sentences and more complex structures, including the time clause “Before the juice is transformed…” and the sequence “after the process of drying and cooling…”. The meaning is generally clear, but some errors in agreement, articles, and sentence construction remain. For example, “The diagram illustrate” should be “The diagram illustrates,” “the process consist” should be “the process consists,” and “it become” should be “it becomes.” The phrase “by a heavy machinery” also has an article problem, while “it is harvested” has an unclear reference that could be avoided by repeating “the sugar cane.” Review subject–verb agreement and article use, and aim for complex sentences that remain grammatically controlled.
