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 a seven step process of manufacturing sugar from sugar cane.

Overall, it is evident that a raw sugar cane undergoes several mechanical stages in order to produce sugar. The stages include growing and harvesting, crushing, purifying and evaporation of the juice, centrifuge and drying and cooling.

Initially, a sugar cane is grown in a field, which takes roughly 12 to 18 months to fully grow. In a second stage, the harvesting is conducted either by hands or mechanically through a tractor and a thresher. While in a crushing stage, the already harvested sugar canes are move through a crusher to transform it into juice form.

During a fourth stage, the juice that has been extracted from sugar cane is purified, using limestone filter. It then is poured into an evaporator where it is heated, untill the juice cusp into syrup. In the next stage is mark by a segregation of crystals and syrup in centrifuge. Ultimately, the sugar crystals are dried and cooled in a large container.

Task Achievement / Task Response: Band 7.0

The response covers the full process and gives a clear overview, identifying the main sequence from growing and harvesting through to drying and cooling. It also includes the key growing period and both harvesting methods, and correctly describes crushing, limestone filtration, heating, and separation in a centrifuge. This supports a clear, relevant account of the diagram. Some details could be more precise: the overview says the stages are “mechanical,” although growing is not a mechanical stage, and the final container is described as “large,” which is not established by the diagram. The explanation of the centrifuge could also state more clearly that it separates sugar crystals from syrup. More exact reporting of these features would strengthen an otherwise complete summary.

Coherence and Cohesion: Band 7.0

The information is arranged in a clear sequence, with an introduction, an overview, and a chronological account of the stages. Sequencing phrases such as “Initially,” “In a second stage,” and “Ultimately” help the reader follow the process, and the paragraphing is appropriate. The progression is generally easy to understand, although a few transitions are awkward or incomplete. For example, “While in a crushing stage” does not connect smoothly to the preceding sentence, and “In the next stage is mark by” disrupts the flow into the centrifuge stage. Use direct transitions such as “Next, the syrup enters a centrifuge” and maintain consistent sentence patterns to make the cohesion more natural and flexible.

Lexical Resource: Band 6.5

The response uses a suitable range of process vocabulary, including “purified,” “evaporator,” “centrifuge,” and “crystals,” and the meaning remains clear throughout. There is some attempt at precise technical description, but several word choices or forms are inaccurate or unnatural, such as “by hands,” “thresher,” and “the juice cusp into syrup.” “Segregation” is also less suitable than a verb such as “separation” in this context. These choices show that the writer can use task-specific vocabulary, but control of collocation and word form is not yet consistent. Aim for standard process descriptions—for example, “harvested by hand,” “mechanically,” and “the juice is concentrated into syrup”—to improve precision and naturalness.

Grammatical Range and Accuracy: Band 6.0

There is a mix of simple and more complex sentence forms, and the overall meaning is usually clear. The opening and overview are controlled, and the sentence describing the growing period uses a relative clause effectively. However, some grammatical errors remain. In “the already harvested sugar canes are move,” the passive verb form is incorrect; “are moved” is needed. “It then is poured” has awkward auxiliary placement, while “In the next stage is mark by” lacks a correctly formed verb phrase. Articles and number also need attention in “using limestone filter” and “a sugar cane.” These errors do not generally prevent understanding, but checking passive constructions, articles, and sentence completeness would improve accuracy.
