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 step-by step process of producing from sugar cane, which consists of seven distinct stages, starting from growing and ending with drying and cooling process.

Overall, it is evident that the process consists of both natural and industrial steps. It transforms raw sugar cane into refined sugar crystal using various methods such as harvesting, crushing,purifying, evaporating and separating.

First, sugar cane is grown for 12 to 18 months before being harvestred by either manually by hand or mechanically with specialised machinery. Once collected, the sugar can is fed into a crusing machine to extract raw juice.

Next, the liquid juice is purified by passing it through a limestone filter. The filtered juice is then heated in a evaporator, where it turns into thick syrup as a water evaporator. following this, the syrup goes into centrifuge machine, which spins rapidly seperate sugar crystals from the liquid. Fianlly the sugar crystals undergo a drying and cooling phase before they are ready for use.

Task Achievement / Task Response: Band 7.5

The response gives a clear account of the seven-stage process, from growing sugar cane for 12–18 months to drying and cooling the sugar. The overview identifies the transformation from cane to sugar and distinguishes natural and industrial steps, while the body covers both harvesting methods and the main processing stages in the correct order. This is a strong, relevant summary of the diagram. Some details could be more precise: “refined sugar crystal” is not quite the diagram’s wording, and the explanation that the evaporator works “as a water evaporator” is unclear and not supported by the visual. A more exact description of heating the juice until it becomes syrup, followed by separation of crystals from syrup, would make the account more consistently precise.

Coherence and Cohesion: Band 7.0

The response is organised effectively into an introduction, an overview and two chronological body paragraphs. Sequencing expressions such as “First,” “Once collected,” “Next,” and “Following this” help the reader follow the process, and the progression from cultivation to the final product is clear. The overview also gives the reader a useful sense of the process before the details begin. Cohesion is not always fully smooth, however: the second paragraph’s list of stages is compressed, and the final paragraph relies heavily on “then” and “following this” to connect steps. The sentence beginning “The filtered juice is then heated” also contains an unclear explanation that interrupts the flow. Use a wider range of links and make each stage-to-stage relationship explicit.

Lexical Resource: Band 6.0

There is adequate process vocabulary, including “harvesting,” “extract,” “limestone filter,” “evaporator,” “syrup,” and “centrifuge,” which allows the stages to be described clearly. The writer also attempts more specific language, such as “specialised machinery” and “spins rapidly.” However, several spelling and word-choice errors reduce precision: “harvestred,” “crusing,” and “Fianlly” are misspelled, while “a water evaporator” is an inaccurate or unclear description of the machine. “Sugar can” is also less precise than “sugar cane,” and “refined sugar crystal” is awkward in this context. Proofread technical terms carefully and choose natural process collocations, especially when describing what each machine does.

Grammatical Range and Accuracy: Band 6.0

The response uses a mix of simple and more complex structures, including a relative clause in “where it turns into thick syrup” and a passive construction in “is purified by passing it through a limestone filter.” Most relationships between stages remain understandable. Some grammatical errors nevertheless persist. In “before being harvestred by either manually by hand or mechanically,” the passive construction is followed by an incorrectly formed contrast; use “harvested either by hand or mechanically.” The article in “in a evaporator” should be “in an evaporator,” and “which spins rapidly seperate” needs a finite verb form, such as “which spins rapidly to separate.” Capitalisation after the full stop in “following this” also needs correction. More accurate control of these forms would strengthen the otherwise clear sentence structure.
