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 5.0)
Above the diagram illustrates the method of rotating the coil and how the turbine of the generator is rotated and how to produce the electricity in a Hydroelectric power station.
Overall, this type of figure describes the Dam is connected with the bank of river, when the level of water is increased towards the river. In the bottom of the dam, there is a small internal, water is flow through the internal during day time and the process is reverse during night time to produce electricity.
A Dam is constructed near to the bank of river, during the High-level-reservoir, the water is reached at the high level, there is a small internal at the bottom of the river and connected to the hydroelectric power station to generate the electricity. When the water is flow through the bottom of the river at Day time and move in side the power station, the turbine is move during the flow of water which produce electricity and that is move to the Power Lines, after this is moves towards the national grid. the process is reverse at night which is also use to produce the electricity

Task Achievement / Task Response — Band 5.0
The response attempts to describe the process but fails to accurately interpret the diagram. The description of the 'internal' and the 'day/night' cycle is factually incorrect based on the provided image, which depicts a standard hydroelectric dam system. The response lacks a clear overview of the main stages (water intake, turbine rotation, and electricity transmission). While it mentions the dam and the turbine, the explanation is confusing and does not clearly outline the mechanical process shown. To improve, focus on accurately identifying the key components—the reservoir, intake, turbine, generator, and power lines—and describing their function in a logical sequence.
Coherence and Cohesion — Band 5.5
The essay is divided into paragraphs, but the logical flow is weak. The transition between the introduction and the body is abrupt, and the progression of ideas is disjointed. Cohesive devices are used, such as 'when' and 'after this', but they are often applied in a repetitive or mechanical way. The referencing is sometimes unclear, particularly when referring to the 'internal' or the 'process is reverse'. Improving the use of linking words and ensuring each paragraph has a clear, singular focus would significantly enhance the readability and logical structure of the report.
Lexical Resource — Band 5.0
The vocabulary is limited and often imprecise. Phrases like 'small internal' and 'move in side' are inaccurate and do not reflect the technical nature of the task. There is a reliance on basic verbs such as 'move' and 'produce' rather than more specific terminology appropriate for a process description, such as 'generate', 'rotate', 'flow', or 'transmit'. To reach a higher band, you should incorporate more precise technical vocabulary related to hydroelectric power, such as 'intake', 'penstock', 'generator', and 'distribution'.
Grammatical Range and Accuracy — Band 5.0
There are frequent grammatical errors throughout the text, including issues with subject-verb agreement ('the turbine is move', 'water is flow') and incorrect sentence structures. Many sentences are run-on or lack proper punctuation, which makes the text difficult to follow. The range of structures is limited, consisting mostly of simple sentences with some attempts at complex ones that are often grammatically flawed. Focusing on basic sentence construction, specifically ensuring correct verb tenses and avoiding unnecessary repetition of 'is', will help improve clarity and accuracy.
