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 flow diagram illustrates the manufacturing process of sugar from sugar cane.It comprises of seven different steps of manufacturing sugar.

Overall, it is clear that making sugar from sugar cane requires two kind of processes, natural process and industrial process.

As in the diagram it is clear that sugar cane grows first which generally requires 12-18 months. In second step harvesting of sugar cane takes place. Harvesting can be done with the help of workers or by using advanced matchiney. After that, crushing of sugarcane take place to seperate all the juice, which then goes for purification by passing it through limestone filter.

After the purification step juice becomes syrup in evaporator by utilizing heat energy. Then this syrup goes to centrifuge matchine, where high speed results in seperation of sugar crystals from syrup. Then these crystals goes for drying and cooling which ultimately results in the formation of sugar.

Task Achievement / Task Response: Band 7.0

The response covers the process from cane growth through to the final sugar, and includes the key duration of 12–18 months, both harvesting methods, the limestone filter, heating, centrifuging, and drying and cooling. The overview also identifies a broad distinction between growing and industrial production, giving the reader a useful summary of the process. Most stages are described in the correct order, and the explanation of syrup becoming sugar crystals is relevant. To make the account more fully developed, state more precisely that the centrifuge separates crystals from the remaining syrup, and avoid the vague phrase “two kind of processes”; the diagram presents a sequence of stages rather than explicitly classifying them into two processes. Overall, the main features are selected and reported clearly, with some room for greater precision.

Coherence and Cohesion: Band 7.0

The response is organised into an introduction, an overview, and two paragraphs describing the stages, which gives it a clear progression. Sequencing expressions such as “In second step,” “After that,” and “Then” help the reader follow the process, and the stages are generally presented in the correct order. The final sentence provides a clear endpoint. Cohesion is sometimes a little mechanical because several sentences begin with “Then” or “After,” and “As in the diagram it is clear” repeats the idea already expressed in the overview. Use a wider range of linking structures and connect related stages more smoothly—for example, explain the transition from evaporation to centrifuging in one linked sentence. These refinements would make the progression feel less formulaic.

Lexical Resource: Band 6.0

There is an adequate range of process vocabulary, including “harvesting,” “purification,” “limestone filter,” “evaporator,” and “centrifuge,” which allows the main stages to be communicated. Some wording is imprecise or unnatural, however: “two kind of processes” is vague, “advanced matchiney” is not an appropriate form, and “seperate all the juice” does not accurately describe crushing, which extracts juice from the cane. Spelling errors such as “matchiney,” “seperate,” and “seperation” also reduce accuracy. Aim for precise process collocations and check spelling carefully. For instance, “extract the juice” and “mechanical equipment” would describe the relevant stages more naturally and accurately.

Grammatical Range and Accuracy: Band 6.0

The response uses a mix of simple and more complex structures, including the relative clause “which then goes for purification” and the clause “where high speed results in separation.” The meaning remains clear throughout. Some grammatical errors persist, particularly with agreement and articles: “two kind of processes” should be “two kinds of processes,” “crushing … take place” should be “takes place,” and “these crystals goes” should be “these crystals go.” The opening also needs a space after the full stop in “sugar cane.It,” and “comprises of” is not the correct construction; use “comprises seven steps” or “consists of seven steps.” More consistent subject–verb agreement and accurate sentence punctuation would improve control.
