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 7.0)

The process diagram outlines the stages of how sugar is produced from sugar cane.

Overall, the process consists of seven stages, which include growing sugar canes, followed by harvesting and crushing them. The later stages involve purifying juice and evaporating it to make syrup and finally drying and cooling of produced sugar.

The process starts with cultivation of sugar cane which takes 12-18 months to mature. The fully grown sugar canes are then harvested by two methods, either by farmers or by heavy machineries. After that, sugar cane is passed through the crushing machines where it is crushed and juice is extracted.The juice then is purified by passing through a limestone filter.

In the later stages, filtered juice is placed in a large container under heat where it is converted into syrup by evaporating excess water. The syrup is then passed through a centrifuge where sugar crystals are seperated from it and finally the obtained sugar crystals are left for drying and cooling. The sugar is ready for the consumption by human beings.

Task Achievement / Task Response: Band 7.5

The response gives a clear account of the process from cultivation through to the finished sugar, and its overview correctly identifies the seven stages and the main progression from cane to juice, syrup and sugar. It also includes key details such as the 12–18-month growing period, the two harvesting methods, limestone filtration and centrifuging. This is a well-focused summary of the diagram. To make the account more fully developed, describe the centrifuge’s role more precisely as separating sugar crystals from the remaining syrup, and avoid adding the unsupported claim that the sugar is ready for human consumption. The main stages are covered, but a little more precision in the final steps would strengthen the report.

Coherence and Cohesion: Band 7.5

The response is organised into a brief introduction, an overview and two chronological detail paragraphs. The sequence is easy to follow, with transitions such as “Overall,” “After that” and “In the later stages” guiding the reader through the process. The division between the initial processing and the later stages is appropriate, and references such as “The juice” and “The syrup” are generally clear. Cohesion is effective overall, though some links are quite formulaic and the final sentence about consumption feels detached from the process description. A more concise ending that completes the sequence, together with a few more varied but natural transitions, would make the progression even smoother.

Lexical Resource: Band 6.5

There is an adequate range of process vocabulary, including “cultivation,” “extracted,” “limestone filter,” “evaporating” and “centrifuge,” which helps convey the stages clearly. The writer also uses relevant terms such as “sugar crystals” and “harvested.” However, some choices are imprecise or awkward: “heavy machineries” is not a natural expression, “passed through the crushing machines” is less direct than describing the cane being crushed, and “ready for the consumption by human beings” is unnecessarily wordy. There are also spelling errors in “seperated.” Greater control of collocation, spelling and concise process language would add the flexibility and precision needed for a stronger performance.

Grammatical Range and Accuracy: Band 7.0

The response uses a mix of simple and complex structures, including the overview clause “which include growing sugar canes” and the time clause “where it is converted into syrup.” Many sentences are clear and grammatically controlled, and the sequence of actions is generally expressed accurately. A few errors remain: “sugar cane is passed” shifts awkwardly from the plural canes in the preceding sentence, and “the obtained sugar crystals are left” is an unnatural construction. The sentence “The juice then is purified” also has less natural adverb placement, while the missing space after “extracted.” is a punctuation slip. These issues do not obscure meaning, but more consistent control of articles, number and sentence phrasing would improve accuracy.
