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 the manufactring process of producing sugar from sugar cane.

Overall, there are seven major steps in the producation of sugar, starting from plantation of sugar cane and later juice production to cooling process. In final step the syrup formed by sugarcane juice is dried and cooled as a result sugar forms.

Firstly, the sugarcane is grown for (12-18 months) after the plant is fully grown, the sugarcane is harvested using machinery or either with hands. In third stage sugarcane gets crushed and sweet juice forms, then a limestone filter is used for the purification of liquid.

Later a evaporation process is done using high heat to convert juice in to a syrup. In sixth step a machine called centrifuge is used to separate sugar crystals from the syrup. Final step include the drying and cooling process the sugar crystals go through a perod of cooling and finally the dried crystals turn into sugar.

Task Achievement / Task Response: Band 7.0

The response gives a clear account of the process and includes its main stages in the correct order, from growing the cane for 12–18 months through harvesting, crushing, purification, evaporation and centrifuging to drying and cooling. The overview identifies the seven steps and the transformation from cane to sugar, while the body adds relevant details such as the two harvesting methods and the limestone filter. This covers the task well. To make the account more fully developed, describe the final separation and product more precisely: the centrifuge separates sugar crystals from syrup, and the diagram labels the final output as sugar. The statement that crystals “turn into sugar” is less exact, since drying and cooling are the final processing stages rather than a separate transformation.

Coherence and Cohesion: Band 6.5

The response is organised into an introduction, an overview and two body paragraphs, and the stages generally progress in the same order as the diagram. Sequencing expressions such as “Firstly,” “Later” and “In sixth step” help the reader follow the process. This is a coherent structure, with some effective progression. However, the linking can feel mechanical, and a few connections are unclear. For example, “starting from plantation of sugar cane and later juice production to cooling process” compresses several stages rather than clearly summarising the sequence. The final sentence also repeats “final” and “process.” Use more precise transitions and clearer references between stages, and group related actions into smoother sentences to make cohesion more flexible.

Lexical Resource: Band 6.0

The response uses a suitable range of process vocabulary, including “harvested,” “crushed,” “limestone filter,” “evaporation” and “centrifuge,” so the reader can understand the production stages. It also attempts more specific terms such as “purification” and “sugar crystals.” However, several spelling and word-choice errors reduce precision: “manufactring,” “producation” and “perod” are misspelled, while “plantation” is not the most natural term for the growing stage. Some phrases are also awkward, including “sweet juice forms” and “a evaporation process.” Aim for accurate spelling and conventional process collocations, such as “the cane is cultivated” and “the juice is heated and concentrated into syrup.”

Grammatical Range and Accuracy: Band 5.5

You attempt both simple and more complex sentence forms, including a time clause (“after the plant is fully grown”) and a passive construction (“is used for the purification”). The sequence remains understandable, but grammatical control is uneven, with errors in articles, agreement, sentence boundaries and clause construction. For example, “a evaporation process” needs the article “an,” and “Final step include” requires a singular verb and an article. The opening overview sentence also has an unclear structure, while “Firstly, the sugarcane is grown … after the plant is fully grown, the sugarcane is harvested” joins clauses awkwardly. Practise building accurate passive sentences and punctuating longer clauses; this will let you express the process with greater control.
