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 illustrates the several manufacturing stages of making sugar from sugar cane.

Overall, the process of making edible sugar consists of seven major steps, beginning with the gowing of sugarcanes for several months and ending with the production of refined sugar.

Initially, the sugarcanes is grown properly for approximately 12-18 months, after that the sugarcane undergo harvesting process, where it is prepared for the next step. The harvested sugarcanes is then crushed to extract the juice. Following this, the juice is purified and filtered by the limestone filter and ready for the next step.

Following the purifying process, the juice is heated and warmed by the evaporator, which converted juice into the syrup. After this process the juice enter into the process called, centrifuge, which helps to convert sugar crystals from the existing syrup. After this whole process, the centrifuge sugar is then converted into the refind and edible sugar by drying and cooling method.

Task Achievement / Task Response: Band 6.5

You identify the process as a sequence and give a clear overview that it has seven stages, from growing sugar cane to producing refined sugar. Most key stages are reported in the correct order, including harvesting, crushing, purification, evaporation, centrifuging, and drying and cooling. The growing period is also accurately stated. Some details are less fully or precisely described: the diagram shows harvesting by either machine or hand, but you only say the crop undergoes harvesting, and the limestone filter is described as purifying and filtering without explaining its role in the sequence. The final stage is presented as converting sugar into edible sugar, whereas drying and cooling are the final treatment of the separated crystals. Including these details would make the account more complete and precise.

Coherence and Cohesion: Band 7.0

The response is organised into an introduction, an overview, and two chronological paragraphs, so the reader can follow the process from cultivation to the final product. Sequencing expressions such as “Initially,” “Following this,” and “After this process” help signal progression, and the stages are generally presented in the correct order. The organisation is clear, though some links are repetitive and the final paragraph’s repeated references to “the process” and “after this” make the progression slightly mechanical. A few references are also imprecise: “the juice” is used after the centrifuge, although the material at that point is syrup and sugar crystals. More varied linking and clearer references to each material would strengthen the flow.

Lexical Resource: Band 6.0

You use an adequate range of process vocabulary, including “manufacturing stages,” “extract the juice,” “limestone filter,” “evaporator,” and “centrifuge.” These terms show awareness of the technical subject, and the main meaning remains clear. However, some word choices and collocations are inaccurate or awkward, such as “grown properly,” “undergo harvesting process,” “centrifuge sugar,” and “converted into the refined and edible sugar.” There are also spelling errors in “gowing” and “refind,” which reduce precision. Aim to use the diagram’s labels directly where appropriate and choose natural process verbs—for example, sugar cane is harvested, juice is evaporated into syrup, and crystals are dried and cooled. This would make the vocabulary more precise and controlled.

Grammatical Range and Accuracy: Band 5.5

You attempt a mix of simple and complex sentences, including a relative clause in “the evaporator, which converted juice into the syrup” and a sequence linked with “after that.” The overall meaning is usually understandable, but some grammatical errors recur. Subject–verb agreement is inaccurate in “the sugarcanes is grown” and “the harvested sugarcanes is then crushed”; tense control is also inconsistent in “which converted” and “the juice enter.” Articles and sentence construction need attention in “undergo harvesting process” and “called, centrifuge.” The comma splice in “for several months and ending…” is not the main issue, but punctuation around clauses and labels should be checked. Practise accurate agreement and consistent present simple forms for describing processes.
