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 depicts the manufacturing process of producing sugar from sugar cane.

Overall, it is clear that the process consists of seven stages, starting with the growing of sugar cane and ending with the drying and cooling of the sugar crystals. The process also involves crushing the sugar cane to extract juice, followed by several stages of purification and processing.

First, sugar cane takes 12–18 months to grow. Once it has fully grown, it is harvested either mechanically or by hand. It is then crushed in a machine to extract the juice. After that, the juice passes through a limestone filter in order to be purified.

In the next stage, the purified juice is heated in an evaporator. As heat is applied from below, the juice is converted into syrup. In the sixth stage, the syrup is passed through a centrifuge, where the sugar crystals are separated from the remaining syrup. Finally, the sugar crystals are dried and cooled, completing the manufacturing process.

AI examiner evaluation

Task Achievement / Task Response — Band 7.0

The response covers all stages of the process clearly and accurately. You have successfully identified the main features, such as the growth period, harvesting, and the transformation from sugar cane to final crystals. The overview is concise and effectively highlights the key stages. To reach a higher band, ensure you explicitly mention the 'main features' as a summary of the entire flow, perhaps by noting the transition from raw agricultural product to refined industrial output. The information is well-selected and logically presented, meeting the requirements of the task effectively.

Coherence and Cohesion — Band 7.5

The essay is well-organized with a clear logical progression. Each paragraph focuses on a specific phase of the process, which helps the reader follow the sequence easily. You have used cohesive devices such as 'First', 'Once', 'After that', 'In the next stage', and 'Finally' to link ideas effectively. The paragraphing is appropriate, and the flow of information is smooth. There is no evidence of mechanical or repetitive use of linking words, and the overall structure is coherent, making the information easy to digest.

Lexical Resource — Band 6.5

You have used a good range of vocabulary appropriate for a process description, such as 'manufacturing process', 'harvested', 'mechanically', 'purified', 'evaporator', and 'centrifuge'. The terminology is accurate and fits the context well. While the vocabulary is sufficient and precise, incorporating a few more sophisticated collocations or synonyms for common verbs (e.g., 'transformed' instead of 'converted') could elevate the lexical range further. Overall, the language is natural and error-free, demonstrating a solid command of topic-specific vocabulary.

Grammatical Range and Accuracy — Band 7.5

The response demonstrates a good variety of sentence structures, including complex sentences using subordinate clauses (e.g., 'Once it has fully grown, it is harvested...'). The grammar is highly accurate, with no noticeable errors in tense, subject-verb agreement, or punctuation. The use of the passive voice is appropriate for a process description, as it focuses on the actions rather than the agents. The control over complex structures is consistent, and the writing is clear and professional throughout.
