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 diagram displays how sugar is produced from sugar cane.

Overall, this manufacturing process consists of seven stages. It starts with growing sugar cane in the first stage and ends with drying and cooling of syrup in the last stage.

In the beginning of the process, sugar cane is grown for 12 - 18 months. Once sugar canes are grown in the first stage, the second stage is harvesting. These harvested sugar canes then are crushed in the following stage. By the end of three stages, juice is produced.

The fourth stage is about purifying this juice. This purification process is done with the help of limestone filter. In the following stage, this purified juice is transformed into syrup. this is done by applying heat via an evaporator. Once the syrup is ready by the end of the fifth stage, sugar crystals are separated from it via centrifuge in the penultimate stage of this process. The process ends with drying and cooling of this syrup, from which sugar crystals were separated in the earlier stage. Once the syurp dries and cools, sugar is produced.

Task Achievement / Task Response: Band 7.0

You cover the process from cultivation through to the final production stage, and the overview correctly identifies seven stages and the starting point. Relevant details include the 12–18-month growing period, limestone filtration, heating in an evaporator and separation in a centrifuge. However, the overview says the process ends with “drying and cooling of syrup,” whereas the diagram shows sugar crystals being dried and cooled after they have been separated from the syrup. The final explanation partly corrects this, but the distinction should be clear throughout. You also omit the two harvesting methods shown. The response addresses the task and reports the main sequence, while a more precise overview and fuller coverage of key details would strengthen it further.

Coherence and Cohesion: Band 7.0

The response is organised into a brief introduction, an overview and two paragraphs that follow the stages in sequence. Linking expressions such as “In the beginning,” “In the following stage” and “Once” help the reader track the process, and references to the “fourth,” “fifth” and “penultimate” stages support progression. Some linking is repetitive, particularly the repeated use of “stage” and “Once,” and the final paragraph could distinguish more cleanly between syrup separation and the drying of sugar crystals. The sentence beginning “By the end of three stages” also interrupts the otherwise smooth stage-by-stage account. Overall, the progression is clear; more varied, precise transitions and tighter connections between related steps would make cohesion more flexible.

Lexical Resource: Band 6.5

You use a suitable range of process vocabulary, including “purifying,” “limestone filter,” “evaporator,” “syrup” and “centrifuge,” which allows you to describe the main stages clearly. Some wording is imprecise or repetitive: “this syrup” is used for the material dried and cooled, although the diagram indicates that sugar crystals are dried after separation, and “sugar canes” is repeated several times. There are also spelling slips in “syurp” and “filter” would be more natural as part of “limestone filtration” in this context. The vocabulary is adequate and includes relevant technical terms, but greater precision in collocation and careful proofreading would provide more flexibility and control.

Grammatical Range and Accuracy: Band 6.5

You use a mix of simple and complex forms, including time clauses such as “Once sugar canes are grown” and passive constructions such as “is produced” and “are separated.” Most sentences communicate the sequence successfully. Some grammatical choices are less controlled: “These harvested sugar canes then are crushed” has awkward adverb placement, and “this is done” begins a sentence without a capital letter. The final sentence, “Once the syurp dries and cools,” also shifts to a present-tense description after the preceding past-tense “were separated,” making the time reference less consistent. These issues do not prevent understanding, but more consistent tense use, sentence-level editing and accurate punctuation would improve control.
