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 schematic diagram depicts the various steps involved in the production of sugar.

Overall, the process begin with the harvesting of sugarcane by humans or by machines.Grinding of sugarcnes,filteration of juice,heating the juice , production of syrup, centrifugation of syrup , cooling and drying of yielded crysals..

The diagram illustrates sugarcanes are harvested after their optimal growth . The growing process completes after 12 to 18 months. Sugarcnes are cropped either by manual labours or by machines.The culled sugarcanes are grinded and crushed to produce juice.Obtained juice is filtered by using limestone filter.Dirt and debris are removed from the juice by limestone filter.In the next step , purified juice is heated in an evaporator. Heat thickens the consistency of juice and it is converted into syrup. Sugar syrup undergoes the process of centrifugation in a specific apparatus. There, sugar crystals get separated from syrup.Finally, crystals are dried and cooled . The final yielded product is called sugar.

Task Achievement / Task Response: Band 7.0

The response covers the main stages and gives a clear overall account of the process, including the 12–18-month growing period, the two harvesting methods, juice purification, evaporation, centrifugation, and final drying and cooling. The explanation that heating turns the juice into syrup and that centrifugation separates crystals is particularly useful. This makes the process understandable and addresses the task well. However, the overview is not fully accurate: it says the process begins with harvesting, whereas growing is the first stage. Some details are also added without support, such as saying the limestone filter removes “dirt and debris.” To strengthen the report, make the overview reflect the complete sequence and keep explanations closely tied to what the diagram shows.

Coherence and Cohesion: Band 6.5

The response has a recognisable structure: an introduction, an overview, and a chronological description of the stages. The sequence from harvesting through crushing, filtering, heating, centrifugation, and drying is generally easy to follow, and phrases such as “In the next step” and “Finally” help guide the reader. The overview, however, lists stages in a fragmented way and does not clearly establish the full progression from growing to the final product. Some links between sentences are also repetitive, with several successive statements beginning with the product or process being described. Use a more complete overview and vary transitions or combine closely related steps to make the progression smoother and less mechanical.

Lexical Resource: Band 6.0

There is an adequate range of process vocabulary, including “evaporator,” “centrifugation,” “limestone filter,” and “sugar crystals,” which helps convey the technical stages. The writer also attempts more formal wording, such as “depicts” and “undergoes.” However, several spelling and word-choice errors reduce precision: “sugarcnes,” “cry[s]als,” “filteration,” and “grinded” are inaccurate, while “yielded product” is an awkward collocation. “Cropped” and “culled” are also not natural choices for harvesting sugar cane. Check spelling carefully and prefer standard process terms such as “crushed,” “filtered,” and “resulting product.” This would make the vocabulary more accurate and natural without requiring a much wider range.

Grammatical Range and Accuracy: Band 5.5

The response attempts both simple and more complex forms, including passive constructions such as “are harvested” and “get separated,” as well as a time clause describing growth. Meaning is generally recoverable, but grammatical control is uneven. The opening overview contains a sentence fragment and an incorrect verb form in “the process begin”; the list that follows is also not a complete sentence. Other examples include “The diagram illustrates sugarcanes are harvested,” which needs a linking structure, and “The growing process completes,” where the verb pattern is incorrect. Missing spaces after full stops and inconsistent punctuation also affect accuracy. Practise complete sentence structures, subject–verb agreement, and accurate passive forms while retaining the useful variety of sentence patterns already attempted.
