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 demonstrates the process of how sugar is produced from sugar cane.

Overall,it is a linear process including seven steps starting from cultivation of sugar cane stalks and ending with drying and cooling of sugar crystals.

Initially,sugar cane grow in fields,growing process take almost 12 to 18 months.Once sugar cane crops reached maximum height,it is harvested by two methods.Sometimes it is harvested by machinary, while sometimes by farmers.After its cutting, send it to crushing machine where sugar cane stalks are pressed and liquid came out in a large container.Then this juice is passed through limestone filter to kill toxic material or any debris and make a purify juice.

After the process of purifying,it is heated in a evaporator to make juice more condence.Then this condence liquid in put into centrifuge to separate sugar crystals from syrup.Finally, drying and cooling is carried out and store dry sugar crystals in a container.

Task Achievement / Task Response: Band 7.0

The response covers the full sequence and gives a clear overview: it identifies seven stages, from growing sugar cane to drying and cooling the crystals. It also includes the 12–18-month growing period and both harvesting methods, then explains the main processing stages in order. This is a well-focused account of the diagram. Some details are less precise: the diagram shows limestone filtering the juice, but does not state that this removes toxic material or debris, so that explanation goes beyond the evidence. The evaporator turns juice into syrup, rather than simply making it more concentrated, and the final stage is described as drying and cooling without explaining that the centrifuge separates crystals from syrup. More exact reporting of these functions would strengthen the coverage.

Coherence and Cohesion: Band 7.0

The information is arranged in a clear progression, with an introduction and overview followed by the growing and harvesting stages, then the processing stages. Sequencing expressions such as “Initially,” “After the process of purifying,” and “Finally” help the reader follow the process. The paragraph break also separates the early stages from later processing. Cohesion is generally effective, although some links are awkward or unclear, as in “After its cutting, send it to crushing machine,” where the subject of the action is not explicit. The repeated use of “process” and “then” could also be varied. More precise references between stages and smoother links between sentences would make the progression feel more controlled.

Lexical Resource: Band 6.0

The response uses an adequate range of process vocabulary, including “cultivation,” “harvested,” “crushing machine,” “limestone filter,” “evaporator,” and “centrifuge.” These terms make the stages recognisable, and the writer attempts more specific language such as “sugar crystals” and “syrup.” However, several word-choice, spelling, and word-form errors reduce precision: “machinary” should be “machinery,” “condence” should be “concentrate” or “thicken,” and “a purify juice” should be “purified juice.” “Kill toxic material” is also an unsuitable collocation for describing filtration. Building accuracy with process verbs and standard collocations would make the vocabulary more precise and natural.

Grammatical Range and Accuracy: Band 5.5

The response attempts both simple and more complex sentence forms, including a relative clause in “where sugar cane stalks are pressed” and a contrast between the two harvesting methods. The sequence remains understandable, but grammatical errors occur in several sentences. For example, “sugar cane grow” needs subject–verb agreement, while “growing process take” needs an article and a matching verb form. “Once sugar cane crops reached maximum height” shifts tense, and “After its cutting, send it” lacks a clear grammatical subject. Articles and sentence punctuation also need attention, as in “in a evaporator” and the missing spaces after commas. More consistent past or present tense and complete clauses would improve accuracy.
