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 illustrates the process of producing sugar from sugar cane .

Overall, there are main seven stages in the process, beginning with the cultivation of sugar cane nad ending with the drying and cooling of the final sugar product. The process involves both manual nad mechnical methods.

First , sugar cane is grown for approximately 12 to 18 months until ready to be harvested . The harvesting stage can be carried out the two ways :by using agricultural machinery or by cutting the plants manually. After harvesting , the sugar cane is passed trough a crushing machine ., which extracts the juice of the plants .

In the fourth stage , extracts juice is purified by passing it trough a lime stone filter to improve the impurities .The purified liquid then transferred to evaporates and the juice becomes thick syrup .

Next, the syrup processed in a contrifuge , which seprates sugar crystals from the remainning liquid . Finally , the sugar crystals are dried and colling in a container . Ones this fianl stage is completed , the sugar is ready for use or packging .

In conclusion, sugar production in seven -stage process that transforms hervested sugar cane into sugar through crusing , purification, evaporation, sepration , drying and colling.

Task Achievement / Task Response: Band 7.0

The response covers the process from cultivation through to drying and cooling, and the overview identifies the seven stages and the two harvesting methods. It also includes the growing period and explains the main transformations: cane is crushed for juice, the juice is purified and evaporated into syrup, and the centrifuge separates crystals from liquid. These details are relevant and generally match the diagram. The final claim that the sugar is ready for use or packaging is not shown, however, and the conclusion largely repeats the overview rather than adding a useful feature. To strengthen the report, keep every statement tied to the visual and make the overview more precise about the sequence and the conversion from cane to sugar.

Coherence and Cohesion: Band 7.0

The information is arranged in a clear sequence, with an opening, an overview, and paragraphs that follow the stages from growing to the final product. Connectors such as “After harvesting,” “Next,” and “Finally” help the reader track the process, and the two harvesting methods are grouped appropriately. The conclusion repeats much of the overview, while some transitions are less smooth—for example, the move from purification to evaporation is compressed into one sentence. Paragraphing and progression are effective overall, but cohesion would be more controlled if each stage were linked with accurate references and the repeated summary were replaced by a concise final point.

Lexical Resource: Band 5.5

The response uses relevant process vocabulary, including “cultivation,” “harvested,” “purified,” “syrup,” and “centrifuge,” which helps convey the stages. However, spelling and word-choice errors are frequent enough to make the vocabulary less controlled: examples include “mechnical,” “trough,” “contrifuge,” “seprates,” and “remainning.” Some combinations are also inaccurate, such as “improve the impurities” and “the sugar crystals are dried and colling.” Use standard process collocations such as “remove impurities” and “dried and cooled,” and check spelling carefully. More precise verbs for each stage would also reduce repetition and make the description sound more natural.

Grammatical Range and Accuracy: Band 5.5

There are attempts at complex sentences, including “The harvesting stage can be carried out the two ways” and the relative clause “which extracts the juice of the plants,” alongside shorter sequencing statements. However, errors in sentence structure and verb forms occur repeatedly. For example, “The purified liquid then transferred” needs a passive verb (“is then transferred”), and “the syrup processed” also lacks an auxiliary. The opening overview has agreement and article problems in “there are main seven stages,” while punctuation spacing and stray full stops interrupt several sentences. These errors sometimes make the relationships between stages less clear. Practise accurate passive constructions, articles, and complete clauses before adding more complex structures.
