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 manufacturing process for making sugar from sugar cane. Overall, the sugar making process involves 7 steps through which the raw sugar cane are transformed into ready to use sugar.

The process starts with the growth of sugar cane which takes around 12 to 18 months in total. Once grown, they are harvested using the agricultural machines and human labour. The tractor harvest sugar cane feild ans collect them in a trunk or a storage area. After collection, they are put into a crushing machine which flatens the sugar cane and extracts the juice of the sugar cane.

After extraction, comes the purfification process where the juice is filtered using the limestone filter. In the fifth step, the filtered juice is heated where evaporation takes place resulting in transformation of juice into syrup. This syrup is then put into centrifuge rotater which moves and seperates the sugar crystals from the syrup. Once seperated, the sugar crystals are collected and moved to the final stage of production which is drying and cooling. After sugar is cooled, it is ready to be used as an ingredient.

Task Achievement / Task Response: Band 7.0

You cover the full sequence and give a clear overview that the process has seven stages, from growing cane to producing usable sugar. The 12–18-month growing period, both harvesting methods, crushing, limestone filtration, evaporation into syrup, centrifuging, and final drying and cooling are all reported in the correct order. This is a strong, relevant account of the main features. Some details, however, go beyond what the diagram shows: the tractor is said to collect cane in a “trunk or a storage area,” and the final sugar is described as ready to be used as an ingredient. These claims are not indicated in the visual. Keep the description closely tied to the labelled stages and avoid adding unsupported details.

Coherence and Cohesion: Band 6.5

The response is arranged in a clear sequence, with an introduction and overview followed by two paragraphs that move from cultivation through processing to the final stage. Time and sequence markers such as “Once grown,” “After extraction,” and “In the fifth step” help the reader follow the process. This gives the account a coherent overall progression. To make the links more flexible and precise, avoid relying on repeated “After” constructions and make references explicit: “they” in “Once grown, they are harvested” could refer to the cane, but the reference is not fully clear. The phrase “After collection” also suggests a separate collection stage that the diagram does not show. More precise transitions would strengthen cohesion.

Lexical Resource: Band 6.0

You use an adequate range of process vocabulary, including “harvested,” “crushing machine,” “extracts the juice,” “limestone filter,” “evaporation,” and “centrifuge,” which makes the stages understandable. There are also attempts at more specific wording, such as “transformation” and “separates.” However, several spelling errors—“feild,” “purfification,” “flatens,” and “seperates”—reduce accuracy, and some choices are imprecise or informal for a process description. “Centrifuge rotater” is not a natural term, while “ready to be used as an ingredient” adds an unsupported use. Aim for accurate technical terms and concise, neutral phrasing; careful proofreading would also improve control.

Grammatical Range and Accuracy: Band 6.0

You use a mix of simple and more complex forms, including the relative clause in “which takes around 12 to 18 months” and the time clause “Once grown.” Most sentences communicate the process clearly, and the present tense is generally appropriate for describing a diagram. Some grammatical errors remain. In “the raw sugar cane are transformed,” the singular or uncountable noun needs a singular verb, or the noun should be pluralised. “The tractor harvest sugar cane” also needs a plural subject or a passive construction to match the general process. In “After extraction, comes the purification process,” the introductory phrase creates an awkward inversion; write “After extraction, the purification process takes place.” Continue checking agreement and sentence structure while retaining varied forms.
