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)

The given man-made process chart represents the production of electricity using geothermal energy .

Overall it is clear that it consist of 5 steps to complete the process . Two commence with cold water and end with the production of electricity by generator.

The first step is a that cold water is pumped into the earth crust at the depth of 4.5 km . Which is followed by the injection of well the cold water comes in contact with hot Rock and water gets heated . Then the hot water is pumped come to the surface of Earth.

Moving ahead the next step is the condenser steam is transferred into the turbine . At the last step steam rotates the turbine and power is transferred to the generator after that generator produced energy . Then electricity is the used for different purposes . Then these step start from the initial stage.

Task Achievement / Task Response — Band 5.0

The response provides a basic overview of the geothermal energy process, identifying the main stages. However, the description is somewhat mechanical and lacks a clear, logical flow. While the key stages are mentioned, the explanation of the process is occasionally confusing, such as the sentence 'the condenser steam is transferred into the turbine', which misinterprets the diagram's flow. The summary of the process is accurate enough to follow, but it lacks the precision and analytical depth required for a higher band score. To improve, ensure that the relationship between the components (e.g., the condenser and the turbine) is described with greater technical accuracy.

Coherence and Cohesion — Band 5.0

The response is organized into paragraphs, but the progression of ideas is often disjointed. The use of cohesive devices is limited and sometimes repetitive, such as the frequent use of 'Then' to start sentences. Referencing is occasionally unclear, for example, 'Which is followed by the injection of well the cold water comes in contact with hot Rock'. This makes the text feel somewhat fragmented. To improve, use a wider variety of linking words and ensure that each sentence logically follows the previous one, creating a smoother narrative flow throughout the report.

Lexical Resource — Band 5.0

The vocabulary is generally adequate for the task but remains quite basic. There are some inaccuracies in word choice, such as 'man-made process chart' (which is unnecessary) and 'condenser steam'. The phrasing is often repetitive, relying on simple verbs like 'pumped' and 'transferred'. To reach a higher band, you should incorporate more precise technical terminology related to energy production, such as 'geothermal reservoir', 'thermal energy', or 'pressurized steam'. Expanding your range of vocabulary will help you describe the process with more sophistication and clarity.

Grammatical Range and Accuracy — Band 5.0

The response contains a mix of simple and complex sentence structures, but there are frequent grammatical errors that occasionally impede readability. Issues include missing articles ('at the depth of 4.5 km'), incorrect verb forms ('generator produced energy'), and awkward sentence construction ('the condenser steam is transferred'). Punctuation is also inconsistent, particularly with spacing around periods and commas. While the meaning is generally understandable, the frequency of these errors prevents the response from reaching a higher band. Focusing on subject-verb agreement and article usage will significantly improve the accuracy of your writing.
