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 below illustrates the production process of preparing sugar from sugar cane.

Overall, the whole process will contain seven steps, beginning with the growth of sugar cane and ending with the production of sugar crystals. The process involves harvesting, crushing, extracting, and purifying the juice before it is dried and converted into sugar.

Firstly, growing sugar cane takes 12 to 18 months, when the sugar cane ripens, it will be harvested. The process of harvesting can take place with machines as well as by human hands. After harvesting, the sugar cane will move towards the crushing procedure, in which it will transform into juice. Furthermore, the juice is filtered by a limestone filter where the large particles present injuice is removed. Subsequently, the juice is then heated at a high temperature, causing the juice to become a syrup through evaporation, and it becomes concentrated,

In the next stage, the concentrated juice is placed in a centrifuge. This machine separates the sugar crystals from the remaining liquid. Finally, the sugar crystals are dried and cooled, resulting in the finished sugar product, which can be used in our homes and offices for sweet taste in tea and much more.

Task Achievement / Task Response: Band 6.5

You cover the main sequence accurately, including the 12–18-month growing period, the two harvesting methods, crushing, limestone filtration, evaporation, centrifuging, and final drying and cooling. The overview identifies the seven stages and the start and end points, giving the reader a clear account of the process. This meets the task well, though some details are less fully or precisely reported: for example, “extracting” is mentioned in the overview but not clearly distinguished as a stage, and the description of filtration adds that “large particles” are removed, which is not specified in the diagram. The final comment about household uses is not needed for a process summary. To strengthen the response further, keep every detail directly grounded in the visual and make the transformation from juice to syrup to separated crystals especially explicit.

Coherence and Cohesion: Band 7.0

The response is organised into an overview followed by a chronological account, and the progression from growing and harvesting through to drying is easy to follow. Sequencing expressions such as “Firstly,” “After harvesting,” “Subsequently,” and “Finally” help guide the reader through the stages. The shift to “In the next stage” also signals the final part of the process clearly. Some linking is slightly mechanical, and the long sentence beginning “Subsequently, the juice is then heated” carries several ideas before ending with a comma, which weakens the flow. The overview also repeats some stages that are then described in detail. For a more polished progression, use fewer repeated transitions and separate each major transformation into a clearly punctuated sentence or paragraph.

Lexical Resource: Band 6.5

You use a suitable range of process vocabulary, including “crushing,” “limestone filter,” “evaporation,” “concentrated,” and “centrifuge,” which helps explain the stages with reasonable precision. There are also attempts at more technical phrasing, such as “separates the sugar crystals from the remaining liquid.” Some choices are less natural or precise: “production process of preparing sugar” is redundant, “the sugar cane will move towards the crushing procedure” is awkward, and “for sweet taste in tea and much more” is informal and unnecessary. The phrase “large particles” also introduces a detail not shown in the diagram. Aim for concise, conventional process collocations and use technical terms only where they accurately describe the visual.

Grammatical Range and Accuracy: Band 6.0

You use a mix of simple and complex structures, including a relative clause in “a limestone filter where…” and a participle clause in “causing the juice to become a syrup.” Most of the process remains understandable, but some grammatical errors and punctuation problems persist. The opening sentence of the body joins two independent clauses with a comma: “takes 12 to 18 months, when…”; use a full stop or a suitable conjunction. The sentence ending “becomes concentrated,” is also left with a comma rather than a full stop. In addition, “injuice” needs a space, and the repeated future form “will be harvested” is less consistent with a general process description than the present simple. Check sentence boundaries and maintain one tense pattern throughout.
