IELTS Writing Task 1 question

The diagram below shows how electricity is generated in a hydroelectric power station.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

Student answer (Band 5.5)

The flow chart illustrates the method of producing light through hydro electric power station.

Overall,the hydro electric power station contains the dam water and for the flow of water they used pipes and a generator inside it.Due to this power lines supply the light to the national grid.

The river water flows down into the high level of reservoir which is stored in the form of dam.Water is stored in the morning time and closed at the night time.Then water can be flown using the pipes for producing electricity during the day time and using pumps at the dark time.Significantly,reversible turbines are also operating into the high level reservoir they will starts operating generator at the day time and night time they use pumps.

The morning time when the generator is operating and the power station starts working and they are providing light to the national grid.In this way electricity is produce.

AI examiner evaluation

Task Achievement / Task Response — Band 5.0

The response attempts to describe the process but struggles with accuracy and clarity. While it identifies the main components like the dam, reservoir, and generator, the description of the process is confusing and contains factual inaccuracies regarding the operation (e.g., mentioning 'morning' and 'night' time, which is not indicated in the diagram). The explanation of the reversible turbine cycle is also unclear. To improve, focus on describing the physical movement of water through the system as shown in the diagram rather than speculating on time-based operations. Ensure that the relationship between the components is described logically and accurately.

Coherence and Cohesion — Band 5.5

The essay is divided into paragraphs, but the logical flow is weak. The introduction is brief, and the body paragraphs lack a clear progression. Cohesive devices are used, such as 'In this way' and 'Significantly', but they are sometimes used incorrectly or do not effectively link the ideas. The referencing is occasionally unclear, making it difficult for the reader to follow the sequence of the hydroelectric process. Improving the use of transition words and ensuring each paragraph has a clear, singular focus would significantly enhance the coherence of the report.

Lexical Resource — Band 5.5

The vocabulary is somewhat limited and repetitive. Phrases like 'producing light' are inaccurate, as the diagram illustrates electricity generation, not light production. There are also issues with word choice, such as 'dark time' instead of 'night' or 'off-peak hours'. While the student uses some technical terms like 'reservoir', 'turbines', and 'generator', the overall range is narrow. To reach a higher band, you should use more precise terminology related to energy production and avoid informal or inaccurate phrasing.

Grammatical Range and Accuracy — Band 5.0

The response contains frequent grammatical errors that occasionally impede clarity. There are issues with subject-verb agreement (e.g., 'they will starts operating'), incorrect verb tenses (e.g., 'electricity is produce'), and awkward sentence structures. The range of structures is limited, relying mostly on simple or poorly constructed complex sentences. Punctuation is also inconsistent, particularly with spacing after commas. To improve, focus on mastering basic sentence construction and proofreading for common errors like subject-verb agreement and verb forms.
