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 process illustrates how electricity is made by geothermal power plant.

Overall, diagram consit approximately 5 stages, however if we see at whole process the cold water converted into hot and than pumped upward and lastly steam go toward grid station to make electricity.

In first step, cold water is store into a huge tank than water is pumped through a pipeline going down approximately 4500 meters, Afterward lower temperature h2o move in three differents injection well furthermore in third stage at the middle of ground hot rocks transform water into hot, again production well pumped hot water up.

In fourth stage hot water put into condenser shifts it to steam, moreover steam is rotated to built power in turbine which is than moved toward generator, whereas generator finally built electricity. When electricity is manufactured grid station will provide electricity to bus bar or electric pole.

Task Achievement / Task Response — Band 5.0

The response provides an overview of the geothermal energy process, but it fails to meet the minimum word count requirement of 150 words, which negatively impacts the overall task achievement. While the main stages are identified, the description lacks the necessary detail and precision expected for an Academic Task 1 response. The summary of the process is somewhat mechanical, and the explanation of the technical stages (such as the condenser and turbine interaction) is slightly inaccurate and under-developed. To improve, ensure all parts of the diagram are described with sufficient clarity and meet the minimum length requirement to allow for a full development of the information provided.

Coherence and Cohesion — Band 5.5

The response is organised into paragraphs, which helps the reader follow the sequence of the process. However, the use of cohesive devices is often repetitive or misused, such as the frequent use of 'furthermore' and 'moreover' in ways that do not always flow naturally. The transition between sentences is sometimes abrupt, and the lack of clear logical progression between the stages makes the text feel disjointed. Improving the variety of linking words and ensuring that each sentence builds logically upon the previous one would significantly enhance the coherence of the report.

Lexical Resource — Band 5.0

The vocabulary is generally adequate for describing a process, but it is quite limited and repetitive. There are several instances of awkward word choices, such as 'built power' instead of 'generate power' and 'h2o' instead of 'water'. The range of vocabulary is restricted, and the student relies on basic terms to describe technical components. To reach a higher band, you should incorporate more precise, topic-specific terminology related to energy production and engineering, and avoid informal abbreviations or imprecise verbs.

Grammatical Range and Accuracy — Band 5.0

The response contains frequent grammatical errors that occasionally impede the flow of information. There are issues with subject-verb agreement (e.g., 'steam go', 'generator finally built'), incorrect verb tenses, and missing articles. The sentence structures are mostly simple or contain errors when attempting more complex constructions. Punctuation is also inconsistent, particularly with the use of commas and run-on sentences. Focusing on basic sentence construction, ensuring correct verb forms, and proofreading for subject-verb agreement would help improve the accuracy of your writing.
