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 6.0)

The diagram illustrates that how the geothermal energy is utilize for generating electricity.

The cold water pumped down deep in earth then passed through geothermal zone where water is heated and then transffered to production well and reaches to condenser then convert into steam. Steam enters into turbine then in generator and produce electricity.

Firstly the cold water pumped down into earth for 4.5 km then injection wall push it to the thermal zone where hot rocks are presents and the water become hot due to high temprature. After it will tranfered to the production wall where water pumps upside. Heated water reaches through the condenser and the condensers covert hot water into steam by adding more. Steams enter through the turbine and revolves around the turbines the turbine push forward the steam toward generator. Generator and turbine produce electricity and then the generator put forward the produced electricity to tower and then the elecrticity will supply from one tower to other.

Task Achievement / Task Response — Band 6.0

The response covers the main stages of the geothermal energy process, from the injection of cold water to the distribution of electricity. However, the description is somewhat mechanical and lacks a clear overview or summary of the process as a whole. While the key features are identified, the explanation of how the condenser functions is slightly confusing and inaccurate based on the provided diagram. To reach a higher band, ensure that the overview highlights the cyclical nature of the process and provides a more precise summary of the transformation stages rather than just listing steps.

Coherence and Cohesion — Band 6.0

The response is organised into paragraphs, which helps the reader follow the sequence of events. However, the use of cohesive devices is quite limited and sometimes repetitive (e.g., 'then' is used frequently). The transition between sentences is often mechanical, and the logical flow is occasionally interrupted by awkward phrasing, such as the transition between the turbine and the generator. Improving the use of linking words like 'subsequently', 'following this', or 'as a result' would help create a smoother progression of ideas and improve the overall coherence of the report.

Lexical Resource — Band 5.5

The vocabulary is adequate for the task but lacks precision and variety. There are several spelling errors, such as 'transffered', 'temprature', 'tranfered', and 'elecrticity', which distract the reader. The use of technical terms is present, but the phrasing is often simplistic (e.g., 'water pumps upside'). To improve, you should focus on using more precise terminology related to energy production and ensure accurate spelling of key technical terms. Expanding your range of verbs beyond 'pushed' or 'reaches' would also demonstrate a stronger command of the language.

Grammatical Range and Accuracy — Band 5.5

The response relies heavily on simple sentence structures, and there are frequent grammatical errors throughout the text. Issues include missing articles ('pumped down deep in earth'), incorrect verb forms ('water is heated and then transffered'), and subject-verb agreement errors ('hot rocks are presents'). While the meaning is generally clear, these persistent errors impede the flow of the writing. To improve, focus on mastering basic sentence construction, particularly the use of articles and consistent verb tenses, before attempting more complex structures. Proofreading for basic errors would significantly enhance the quality of your writing.
