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 7.0)

The diagram shows the multi-stage processes of manufacturing sugar from sugarcane which involves steps such as growth of the sugarcane, extraction of sugarcane juice and purification of sugarcane which results in pure sugar.

Overall there are seven steps in sugarcane manufacturing which starts from growth and the extraction process. Sugarcanes grow out of the ground which is cultivated after 12 to 18 months on farm machineries such as a harvester and tractors or manually by a farmer. The harvested sugarcane is placed in a crushing machine that squeezes it which produces sugarcane juice.

As for the purification steps, the juice is passed through a limestone filter and then poured into an evaporator. The evaporator heats up which transforms the juice into a syrup. Later, the syrup is spun in a centrifuge where its centrifugal force seperate the sugar crystals from the syrup. The purified sugar is now placed in a container where it is dried and cooled.

Task Achievement / Task Response: Band 7.0

You cover the full sequence and give a clear overview that the process has seven stages, beginning with cane growth and ending with dried and cooled sugar. The account includes the key transformations—crushing produces juice, evaporation turns it into syrup, and centrifuging separates sugar crystals—so the main features are accurately selected. You also mention the 12–18-month growing period and both harvesting methods. To make the report more fully developed, describe the final product as sugar crystals and clarify that the centrifuge separates them from the remaining syrup; “purified sugar” is slightly imprecise. The opening also repeats several stages rather than adding a distinct overview of the process’s overall progression. Overall, the response addresses the task clearly, with only limited imprecision and scope to sharpen the overview.

Coherence and Cohesion: Band 7.0

The information is organised in a clear sequence, and the paragraphing separates the initial stages from the later purification and finishing stages. Transitions such as “Overall,” “As for the purification steps,” and “Later” help the reader follow the process. The progression from growing and harvesting through crushing, filtering, evaporation, centrifuging, and drying is easy to understand. Some linking is a little mechanical, however, and the first paragraph’s list of growth, extraction, and purification partly repeats information that is then explained in detail. You could make the overview more concise and use clearer references between stages—for example, “the resulting juice” and “the separated crystals”—to improve flow without adding unnecessary transitions.

Lexical Resource: Band 6.5

You use a suitable range of process vocabulary, including “crushing machine,” “limestone filter,” “evaporator,” “centrifuge,” and “centrifugal force.” These terms make the stages understandable, and “transforms” and “separate” help describe changes and functions. Some word choices and collocations are less precise: “sugarcane manufacturing” suggests the cane itself is manufactured, while “pure sugar” and “purified sugar” do not accurately name the crystals produced. “Farm machineries” is also an unnatural phrase, and “spun” is less precise than a process verb such as “rotated.” Greater control of these expressions would make the description more natural and exact; the range is adequate, but occasional inaccuracies remain.

Grammatical Range and Accuracy: Band 6.5

You use a mix of simple and complex structures, including the relative clause in “a crushing machine that squeezes it” and the time clause “which transforms the juice into a syrup.” Most sentences communicate the process clearly. Some grammatical errors remain, particularly in agreement and verb forms: “the multi-stage processes … which involves” has a plural subject with a singular verb, and “centrifugal force seperate” should use the third-person singular form “separates.” The sentence “The evaporator heats up which transforms the juice” also needs clearer clause structure, such as “The juice is heated in an evaporator, which transforms it into syrup.” More consistent passive constructions would suit a process description and improve control.
