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 6.0)

The given diagram shows the manufacturing process for making sugar from sugar cane. There are numerous stages in the development of sugar.

The first process is growing sugar canes which takes about 12-18 months approximately.

The second stage is harvesting of sugar cane. Farmers harvest these canes in the ground. Mostly, it is done with the help of machinery like tractors.

In the next step, these grown sugar canes are crushed using a wooden machine and it gives sugar cane juice. The step four shows the purifying of juice as it passes through a limestone filter. After that, this purified juice goes through a process of evaporation in which the filtered juice is heated in evaporator and it becomes a syrup.

Diagram six shows the process of centrifuge in which the sugar crystals are seperated from the syrup. Once sugar and syrup are seperated, the sugar is dried and cooled down. Thus, this cycle of making sugar from sugarcane is completed.

Task Achievement / Task Response: Band 5.5

You cover the main sequence from growing cane through harvesting, crushing, purification, evaporation, centrifuging, and drying and cooling, and you correctly include the 12–18-month growing period. However, the overview is not clearly stated: “There are numerous stages” is general rather than identifying the process’s start and end or its key transformation from cane to sugar. Some details are inaccurate or incomplete. The diagram shows mechanical and manual harvesting, but you mainly describe machinery; it shows a crusher, not specifically a “wooden machine.” Also, “this cycle” suggests a repeating process, whereas the diagram presents a linear sequence. A clearer overview and more precise coverage of both harvesting methods would make the report more complete.

Coherence and Cohesion: Band 6.0

The stages are presented in a generally logical order, and sequencing phrases such as “The first process,” “The second stage,” “In the next step,” and “After that” help the reader follow the process. The final sentence also provides a clear sense of completion. However, the response is arranged as one continuous paragraph, so the overview and process details are not distinguished. Some linking is repetitive and mechanical, particularly the repeated use of “step” and “stage.” The reference “Diagram six” is also less smooth than a transition that connects the centrifuge directly to the preceding evaporation stage. Grouping the overview separately and varying transitions would improve the flow and cohesion.

Lexical Resource: Band 6.0

You use an adequate range of process vocabulary, including “harvesting,” “crushed,” “purifying,” “evaporation,” “centrifuge,” and “sugar crystals,” which makes the stages understandable. Some choices are imprecise or repetitive: “development of sugar” is not a natural description of production, and “wooden machine” adds a material not shown in the diagram. “Farmers harvest these canes in the ground” is also an awkward way to describe harvesting. There are spelling errors in “seperated,” repeated twice, and the phrase “sugar cane juice” could be expressed more concisely as “cane juice.” More precise process collocations and careful spelling would strengthen the vocabulary.

Grammatical Range and Accuracy: Band 5.5

The response includes both simple sentences and some longer structures, such as “The step four shows the purifying of juice as it passes through a limestone filter.” Most meanings remain clear, and the sequence is generally expressed with appropriate present-tense forms. However, some grammatical patterns are awkward or inaccurate. For example, “The second stage is harvesting of sugar cane” needs a more natural article or possessive construction, while “The step four shows” has an incorrect word order for the ordinal. “Once sugar and syrup are separated” would also be clearer with an article before “sugar” or a more precise noun phrase. Aim for more consistently controlled sentence patterns and check articles and ordinal constructions.
