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 7.5)

The provided diagram illustrates the process through which sugar is produced from sugar cane.

Overall, it can be observed at a glance that there are seven stages in this process, beginning with the growing of sugar cane and culminating in cooling of sugar crystals. Moreover, evaporation appears to be the most important stage in this procedure.

As the first step, sugar canes are cultivated and grown for 12-18 months. These are then harvested either traditionally ( by farmer) or by advanced agricultural harvester. Following this, sugar canes are crushed in a machine in order to extract juice, which is then purified. Limestone filter assists in this process.

At a subsequent stage, purified juice is heated in an evaporator to increase its concentration and viscosity resulting in transformation of juice into syrup. Next, the syrup is transferred into a centrifuge which separates sugar crystals from syrup, followed by drying and cooling of sugar crystals.

Task Achievement / Task Response — Band 7.5

The student successfully addresses all parts of the task by providing a clear and comprehensive summary of the sugar manufacturing process. The response covers all seven stages depicted in the diagram, from growing and harvesting through to the final cooling phase. An effective overview is provided in the second paragraph, highlighting the total number of stages and identifying key features such as cultivation, evaporation, and crystallisation. Furthermore, the student accurately reports specific details, such as the 12-18 month growing period and the two distinct harvesting methods. The information is logically selected and accurately presented without introducing extraneous details, fully satisfying the requirements for Task Achievement at a high band level.

Coherence and Cohesion — Band 7.5

The response is logically organized with a clear progression from the beginning to the end of the manufacturing process. The text is appropriately divided into four paragraphs: an introduction, an overview, and two body paragraphs detailing the sequential steps. Cohesive devices are used effectively to guide the reader through the process, with transition markers such as 'As the first step', 'Following this', 'At a subsequent stage', and 'Next'. Paragraphing is logical and manages the flow of information smoothly, ensuring that relationships between stages are clear and easy to follow throughout the response.

Lexical Resource — Band 7.0

The student demonstrates a sufficient and generally appropriate range of vocabulary suitable for describing a technical process. Words and phrases such as 'cultivated', 'concentration', 'viscosity', 'transformation', and 'centrifuge' show a good attempt at incorporating less common lexical items. There are, however, a few minor inaccuracies or awkward phrasings, such as missing articles ('by farmer' instead of 'by a farmer' or 'by farmers', and 'cooling of sugar crystals' instead of 'the cooling of the sugar crystals'). Despite these occasional slips, the vocabulary is precise enough to convey the meaning clearly and effectively without impeding communication.

Grammatical Range and Accuracy — Band 7.0

The student demonstrates a good mix of simple and complex sentence structures, incorporating relative clauses, participial phrases, and passive voice constructions appropriately for a process description (e.g., 'sugar canes are crushed in a machine in order to extract juice, which is then purified'). The majority of sentences are grammatically sound and error-free. Minor errors are mostly restricted to missing articles, such as 'by farmer' and 'in evaporator'. Punctuation is generally accurate, and control over complex grammatical forms is sufficient to support clear communication throughout the task.
