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 represent the various stages involved in the production of sugar from sugar cane.

Overall, they are 7 stages involved in the conversion of sugar cane to sugar. It starts with the growth of these sugar canes, these growth takes about a year and 6 months, which is later harvested automatically or manually. This is later processed until it get to the final stage for human consumption.

When these sugar cane are fully grown, taking about 12-18 months, it is harvested either with the use of an harvester machine or with the use of a cutlass manually. The next process is transferring the harvested sugar cane into a crusher to get it juice. The juice gotten is placed in a funnel to filter any impurities. This clear juice is heated into a syrup in an evaporator.

The next stages include placing the syrup in a centrifuge machine to separates any crystals from the syrup, this almost ready sugar is now taken into the last and final stage of production, where it is placed in a container to cool and dry off . At this point the sugar is ready for human consumption.

Task Achievement / Task Response: Band 7.0

The response covers the process from cane growth through to drying and cooling, and the overview identifies the seven stages and the two harvesting methods. It also includes the stated growing period of 12–18 months and correctly describes crushing, filtering, evaporation and centrifuging. These details make the account relevant and generally complete. However, the final claim that the sugar is ready “for human consumption” is not shown in the diagram, and “funnel” is less precise than the limestone filter depicted. To strengthen the report, describe the final stage only as drying and cooling, and use the diagram’s specific labels where possible. The main stages are clear, though some descriptions could be more exact.

Coherence and Cohesion: Band 6.5

The response is organised into an introduction, an overview and two paragraphs that follow the process in sequence. This gives the reader a clear route through the stages, and linking expressions such as “The next process” and “The next stages” help signal progression. The overview also usefully groups the process from growth to the final product. However, several transitions are repetitive, and references such as “This” and “these sugar cane” are not always clear. The final paragraph combines centrifuging and drying in a long sentence, making the relationship between the stages less smooth. More varied sequencing language and clearer sentence boundaries would make cohesion more flexible and precise.

Lexical Resource: Band 6.0

The response uses a suitable range of process vocabulary, including “harvested,” “crusher,” “filter,” “evaporator,” “syrup” and “centrifuge.” These terms allow the reader to follow the production stages, and “automatically or manually” conveys the two harvesting methods. There are also some imprecise or awkward choices: “cutlass” is not the clearest description of the tool shown, “funnel” does not match the limestone filter, and “juice gotten” is an unnatural collocation. “Almost ready sugar” is also unclear. Aim for more precise process terminology and natural combinations, such as “the resulting juice” and “sugar crystals,” while avoiding unsupported claims about consumption.

Grammatical Range and Accuracy: Band 5.5

The response attempts both simple and complex sentences, including a time clause (“When these sugar cane are fully grown”) and a relative clause (“where it is placed…”). However, errors in agreement, verb forms and sentence construction are noticeable. For example, “The diagram represent” should be “The diagram represents,” “they are 7 stages” should be “there are seven stages,” and “these growth takes” has incorrect agreement. The construction “to separates” also needs the infinitive “to separate.” Some sentences are overloaded, particularly the one beginning “The next stages include,” and punctuation around the final stage is uneven. Check subject–verb agreement and verb forms, and divide longer descriptions into controlled sentences.
