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)

Electricity are produced by various method but the most important method to produce electricity are geothermal . In this method, geothermal energy are consume to generate electricity. Below, the diagram show that complete way to generate electricity. In the first step, a container that are fulfill with cold water and water are pulled down into the earth upto 4.5 km and at the second stage the injection well pass water at geothermal zone contain hot rocks. Then, it reached at third stage that are the production well. At this stage, water are hot then hot water are pumped up to the earth surface. when this hot water are reached at the suface of earth then it passed at the condenser where hot water are converted in the form of steam after the condenser turbine are fixed at the end of the condenser . This steam help to turn the turbine and it generate eletricity and stored in a generator and at the end it transfared into the large transformer.

AI examiner evaluation

Task Achievement / Task Response — Band 5.0

The response covers the main stages of the geothermal energy process, from the injection of cold water to the final distribution of electricity. However, the overview is weak; it lacks a clear summary of the overall process or the key transformation involved. The description is largely a step-by-step narration, which misses the opportunity to highlight the cyclical nature of the system or make meaningful comparisons between the stages. While the main features are identified, the lack of a clear introductory overview and the somewhat repetitive nature of the description limit the response to a Band 5.0 level.

Coherence and Cohesion — Band 5.0

The response is presented as a single block of text, which significantly hinders readability and logical progression. While there is a chronological sequence (e.g., 'In the first step', 'at the second stage', 'at the end'), the lack of paragraphing makes the text feel like a list of instructions rather than a cohesive report. Cohesive devices are used, but they are often mechanical and repetitive. The transition between ideas is sometimes abrupt, and the lack of clear paragraph breaks makes it difficult for the reader to follow the distinct phases of the process.

Lexical Resource — Band 5.0

The vocabulary is somewhat limited and repetitive, relying heavily on basic terms like 'water', 'hot', and 'generate'. There are several instances of inaccurate word choice, such as 'consume' instead of 'utilized' or 'harnessed', and 'fulfill' instead of 'filled'. The phrasing is often simplistic, and there is little attempt to use more precise technical vocabulary related to geothermal energy, such as 'geothermal reservoir', 'thermal energy', or 'pressurized'. The errors in word choice are noticeable and occasionally make the text feel unnatural, though the meaning remains generally clear.

Grammatical Range and Accuracy — Band 5.0

The response contains frequent grammatical errors, particularly regarding subject-verb agreement (e.g., 'Electricity are produced', 'diagram show', 'water are consume'). There are also persistent issues with articles and pluralization (e.g., 'at the suface of earth', 'at the condenser'). The sentence structures are predominantly simple or contain errors when attempting complex constructions. The high frequency of basic grammatical mistakes, especially with auxiliary verbs and plurals, significantly impacts the accuracy of the writing and prevents it from reaching a higher band score.
