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 diagram provides a information about the how geothermal energy is used to produce electricity.
Overall it is crystal clear that there are approximately five steps for the production of electricity. In the beginning cold water is pumped down about 4.5 km and ends with the final step through rotation of steam in the turbine.
At a fleeting glance Firstly the cold water pumped downward through injection well about 4.5 km into the earth by following this process cold water sent to geothermal zone where water water pass through boiling method by increasing the temperature with hot rocks and then hot water pumped upward direction through the production well as following.
Moving further, moreover the condenser inhibit of hot water converted into steam which rotate over turbine all time when steam is produced and then pass to generator which produces the electricity. the following steps are used to produce electricity.

Task Achievement / Task Response — Band 5.0
The response identifies the main features of the geothermal process, such as the injection well, the geothermal zone, and the turbine/generator. However, the description is somewhat mechanical and lacks a clear, logical flow. The overview is present but could be more effectively integrated. While the key stages are mentioned, the explanation of the process is occasionally confusing, particularly in the description of the condenser and the steam rotation. To improve, ensure that the relationship between the components is described with greater precision and that the summary highlights the cyclical nature of the process more clearly.
Coherence and Cohesion — Band 5.0
The essay uses some cohesive devices like 'Firstly', 'Moving further', and 'moreover', but these are often used incorrectly or redundantly. For instance, 'At a fleeting glance' is an inappropriate phrase for a technical report. The paragraphing is present, but the internal structure of the paragraphs is weak, with sentences feeling disjointed rather than flowing logically. The referencing is sometimes unclear, such as the phrase 'as following' at the end of a paragraph. Improving the use of linking words and ensuring each paragraph has a clear, singular focus would significantly enhance the readability and coherence of your writing.
Lexical Resource — Band 5.0
The vocabulary is somewhat limited and repetitive. You rely on basic terms like 'cold water' and 'hot water' throughout the text. There are also issues with word choice and collocation, such as 'boiling method' and 'condenser inhibit of hot water'. These errors occasionally make the technical process difficult to follow. To reach a higher band, you should aim to use more precise technical terminology (e.g., 'geothermal reservoir', 'thermal energy', 'pressurized steam') and avoid informal or filler phrases like 'crystal clear' or 'at a fleeting glance', which are not suitable for an Academic Task 1 report.
Grammatical Range and Accuracy — Band 5.0
The response contains frequent grammatical errors that affect the clarity of the writing. There are issues with article usage ('a information', 'the turbine'), sentence structure (run-on sentences), and verb forms ('water water pass', 'which rotate'). Many sentences are simple or poorly constructed, lacking the complexity required for higher bands. For example, 'the condenser inhibit of hot water converted into steam' is grammatically incoherent. To improve, focus on basic sentence construction, subject-verb agreement, and the correct use of articles. Proofreading for these fundamental errors will help ensure that your meaning is conveyed accurately to the reader.
