IELTS Writing Task 1 question

The diagram below shows how geothermal energy is used to produce electricity.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

Student answer (Band 5.0)

This diagram shows how to geothermal energy is used to produce electercity. Over all it is edvict that the diagram represent different process to p[roduce electricity.

At first step cold water pumped down 4.5 km to the well. Moreover it is injected to the well. At second stage water went to the geothermal zone which is hot rock. Meanwhile at third point water become hot and pumped up from the production well to upword in the form of condensation.

Additionally at forth that hot water which is in condencer converted it into steam. Furthermore that steam went into the turbine at fifth step. However that turbine is getting energy from that steam.

That energy shiffted towords the generator at sixth step. In last step that energy used into the generator and produced electercity. Which transmitted that electercity towords the tower. Which used to supply that geothermal electercity towords the whole area.

AI examiner evaluation

Task Achievement / Task Response — Band 5.0

The response addresses the task by describing the geothermal energy production process. However, the overview is weak and lacks a clear summary of the main features or trends. While the steps are identified, the description is somewhat mechanical and lacks the analytical depth required for a higher band. The response covers the stages from injection to electricity distribution, but the lack of a cohesive summary of the overall process limits the score. To improve, ensure the overview highlights the cyclical nature of the process rather than just listing steps.

Coherence and Cohesion — Band 5.5

The response uses some cohesive devices such as 'At first step', 'Moreover', 'Additionally', and 'Furthermore'. However, the use of these devices is often repetitive and mechanical. Paragraphing is present but could be more effectively used to group the stages of the process logically. The progression of ideas is clear, but the flow is occasionally interrupted by awkward phrasing and repetitive sentence structures. Improving the variety of linking words and ensuring smoother transitions between the stages of the diagram would enhance the coherence of the report.

Lexical Resource — Band 5.0

The vocabulary is limited and contains several spelling errors, such as 'electercity', 'edvict', 'p[roduce', 'condencer', and 'shiffted'. The range of vocabulary is basic and repetitive, relying heavily on simple verbs like 'pumped', 'went', and 'used'. There is little attempt to use more precise or technical terminology related to geothermal energy production. To achieve a higher score, you should focus on accurate spelling and expanding your range of vocabulary to include more specific terms related to the process, such as 'geothermal reservoir', 'thermal energy', or 'power grid'.

Grammatical Range and Accuracy — Band 5.0

The response relies primarily on simple sentence structures. There are frequent grammatical errors, including issues with articles ('the well'), verb tenses ('water went'), and word order ('pumped up from the production well to upword'). Some sentences are fragmented or lack proper subject-verb agreement. While the meaning is generally understandable, the high frequency of errors in basic grammar and punctuation hinders the overall quality of the writing. Focusing on sentence variety and proofreading for basic grammatical accuracy would significantly improve your performance.
