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 illustration presents the process of producing sugar from sugar cane.

Overall, the process starts with growing and harvesting sugar cane. After that it is processed through several mechanical and chemical processes to produce sugar.

Firs step to produce sugar is to grow the sugar can which takes from 12 to 18 months. After that it is cut by farmers and it is processed through harvesting machine to separate body part from leaves. And the main body of sugar cane is then send to mills where is is processed further.

In industry, these sugar canes parts are crushed to convert it into juice and which is then purified by passing through limestone filters to separate any impurities. After that juice is evaporated to reduce water content in evaporator to make syrup out of juice. After that it is passed through centrifuge process where sugar crystals are separated from syrup which are then dryed and cooled to make sugar.

Task Achievement / Task Response: Band 6.5

You cover the main stages in the correct order, including the 12–18-month growing period, crushing, limestone filtration, evaporation, centrifuging, and final drying and cooling. The overview also identifies the start and end of the process. This gives the response a clear account of the diagram. Some details, however, are less fully or accurately reported: the diagram shows harvesting by either a machine or by hand, not that farmers cut the cane and a machine then separates the stalk from its leaves. The description of the centrifuge and the final product is relevant, but the overview could more clearly summarise the transformation from cane to juice, syrup, and sugar. More precise coverage of the two harvesting methods would strengthen the response.

Coherence and Cohesion: Band 7.0

The response is organised into an introduction, an overview, and two paragraphs describing the stages, with the process generally moving in the correct sequence. Linking expressions such as “After that” and “In industry” help readers follow the progression, and the final sentence brings the process to its endpoint. However, “After that” is repeated several times, making some connections mechanical, while “And” begins a sentence in the middle of the process description. The transition from harvesting to crushing could also be clearer, since the account introduces two harvesting methods as though they occur successively. Use a wider range of sequencing and result links, and group related stages so the progression feels more deliberate.

Lexical Resource: Band 6.0

You use relevant process vocabulary, including “limestone filters,” “evaporated,” “centrifuge,” and “sugar crystals,” which allows you to describe the diagram’s key operations. There is also some variation in how you refer to the material, such as “juice” and “syrup.” However, several choices are imprecise or awkward: “body part” does not clearly identify the cane stalk, “mills” is not shown in the diagram, and “passed through centrifuge process” is an unnatural collocation. Spelling errors such as “dryed” and “Firs” also reduce accuracy. Aim for precise process terms and check spelling and word forms; this would make the vocabulary more flexible and reliable.

Grammatical Range and Accuracy: Band 5.5

You attempt both simple and more complex sentences, including clauses linked with “which” and “where,” and the overall meaning remains understandable. However, some grammatical errors recur. For example, “Firs step” is missing an article and has an incomplete opening structure; “the sugar can” has a number-agreement problem; and “is then send” uses the wrong verb form. In “where is is processed further,” the repeated subject and unclear clause structure interrupt the sentence. The long sentence beginning “In industry” also contains a faulty connection in “juice and which is then purified.” Practise accurate passive forms and sentence boundaries, and proofread for agreement, articles, and repeated words.
