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 6.0)

The diagram illustrates different stages of how sugar been produce from sugar cane.

Overall, the longest process is done in fields initially by growing and harvesting before it enter in an industry to turn those sugar cane into sugar through different stages involves turning sugar cane different form such as from liquid to crystals then into powder form.

First the sugar cane grows in the field for 12-18 months then harvesting is done both by hands and machinery.

The harvested sugar cane goes through process of crushing which transform them into juice. This juice filtered by limestone in this stage.

The purifying juice then added into evaporator where the juice became syrup by heating it up. Centrifuge stage separates crystals from the syrup which is different from filtering the juice because it is a separation stage, meanwhile filtration was a purifying method. After sugar crystal been separated from sugar crystals sugar is obtain as bt product after going through drying and cooling process.

Task Achievement / Task Response: Band 6.5

You cover the main stages in the correct order, including the 12–18-month growing period, the two harvesting methods, crushing, limestone filtration, heating, centrifuging, and final drying and cooling. The overview also recognises the broad progression from cane to processed sugar, and the distinction you make between purification and separation shows some understanding of the stages. This meets the task well, with some features more fully reported than others. However, the overview says the final product becomes “powder form,” which is not specified in the diagram, and the claim that the longest process is growing and harvesting is not clearly supported. The final centrifuge description is also confused. For a stronger response, keep the overview strictly grounded in the diagram and describe the output simply as sugar.

Coherence and Cohesion: Band 6.0

The response has a recognisable overall structure: an introduction and overview are followed by a chronological account of the process. Sequencing words such as “First,” “then,” and “After” help the reader follow the stages, and the explanation of filtration versus centrifuging attempts to connect related steps. However, the overview sentence is overloaded, and the final sentence repeats “sugar crystals” and makes the sequence difficult to follow. Some links are also mechanical, while references such as “This juice” and “The purifying juice” are not always smoothly connected to the preceding stage. Use one clear paragraph for the overview and group the stages into concise, logically linked sentences, with each pronoun referring unambiguously to a material or stage.

Lexical Resource: Band 6.0

You use a relevant range of process vocabulary, including “harvesting,” “crushing,” “limestone,” “evaporator,” “syrup,” “centrifuge,” and “drying and cooling.” These terms show that you can describe the diagram’s technical stages, and the contrast between “filtering” and “separation” is a useful attempt at precision. Some word choices and forms are inaccurate or awkward, however: “sugar been produce,” “different form,” “powder form,” and “bt product” reduce naturalness or clarity. “Longest process” is also an imprecise description of the growing and harvesting stages. Aim for accurate process collocations and avoid adding a product form that the diagram does not show; careful proofreading would also catch the spelling error.

Grammatical Range and Accuracy: Band 5.0

You attempt both simple and more complex sentences, including a relative clause in “which transform them into juice” and a comparison explaining the difference between filtration and centrifuging. The sequence is generally understandable, but errors in verb forms, agreement, articles, and sentence construction are persistent enough to limit accuracy. Examples include “how sugar been produce,” “before it enter in an industry,” “This juice filtered,” and “After sugar crystal been separated.” The long overview sentence also combines several ideas without secure grammatical control. Practise forming passive process descriptions consistently—for example, “the cane is crushed” and “the juice is filtered”—and check subject–verb agreement and tense. Shorter, complete sentences would help you express the stages more accurately.
