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 given diagram illustrates the steps involved in the making of sugar from sugar cane.

Overall, it is a seven step process. Starting from growing the sugar canes that takes several months. After growing it is passed through various steps resulting in sugar.

It takes 12 to 18 months to grow Sugar cane. Then these sugar canes are harvested either with harvesting machine or by labour. Harvested sugar canes are then passed through crushing machine that crushes sugar canes in to juice.

Sugar cane juice is purified with the help of funnel having limestone filter. After purification, juice is evaporated by means of heat. Heating the juice gives a more viscous consistency, resulting in syrup. After the syrup is formed, there exists sugar crystal those are seprated by using centrifuge. Sugar crystal will come to surface as they are heavier. These are then collected, dried and cooled. Following all these steps sugar is produced.

Task Achievement / Task Response: Band 6.5

You cover the main stages in the correct order, from the 12–18-month growing period through harvesting, crushing, purification, evaporation, centrifuging and final drying and cooling. The overview identifies a seven-stage process and its outcome, while the body includes relevant details such as the two harvesting methods and the use of heat to turn juice into syrup. This gives the account a clear factual basis. Some details are less fully or accurately reported: the centrifuge is described as bringing crystals to the surface because they are heavier, which is not stated in the diagram, and the limestone filter is called a “funnel.” To strengthen the response, report only what the visual supports and make the overview more informative by summarising the transformation from cane to juice, syrup and crystals.

Coherence and Cohesion: Band 6.5

The response is arranged in a sensible sequence, with an introduction, a brief overview and a body that follows the process from cultivation to the finished sugar. Time and sequence markers such as “Then,” “After purification” and “After the syrup is formed” help the reader follow the stages. The overall progression is clear, though some linking is mechanical and the overview is fragmented: “Starting from growing the sugar canes that takes several months” is not a complete sentence. References such as “it” in “After growing it is passed” are also unclear because the process involves several materials and stages. Use complete overview sentences and name the material at key transitions—for example, “the juice is then heated”—to make cohesion more precise and less dependent on repeated sequencing phrases.

Lexical Resource: Band 6.0

You use a suitable range of process vocabulary, including “harvested,” “crushing machine,” “purified,” “evaporated,” “syrup” and “centrifuge,” which allows you to describe the stages clearly. There are also attempts at more specific wording, such as “viscous consistency.” However, some choices are inaccurate or awkward for this diagram: “funnel” does not precisely describe the limestone filter, and “come to surface” is an imprecise description of the separation. “Sugar cane” and “sugar canes” are also used inconsistently. Spelling errors such as “seprated” reduce accuracy, while phrases like “there exists sugar crystal” sound unnatural. Aim for precise process collocations and check spelling and plural forms; this would make the vocabulary more controlled and natural.

Grammatical Range and Accuracy: Band 6.0

You use a mix of simple and more complex forms, including the passive constructions “are harvested” and “are then passed,” which are appropriate for describing a process. Most of the sequence remains understandable, but some grammatical errors persist. The overview fragment “Starting from growing the sugar canes that takes several months” needs a main clause, and “After growing it is passed” has an unclear subject and an awkward structure. In “Sugar crystal those are seprated,” the relative clause is not formed correctly; write “Sugar crystals are separated.” There are also agreement and article issues in “that crushes sugar canes” and “a more viscous consistency.” Practise complete sentences, clear subjects and accurate plural agreement while retaining the useful passive forms.
