Student answer (Band 5.0)

The given diagram illustrates that how the electricity is generated in hydroelectric power station.

overall looking more details in diagram its shows how electricity is generated in hydroelectric power station.In the diagram there is several process how the electricity is generated in hydroelectric power station.

from the begining process the water flows from river and Dam is made to control high level reservor of water .Usually the dam in day remains open and at night the dam is closed.In day the flow of water is used to generate electricity and at night the flow of water pumping.Both the water flows at day and night reached to power station and electricity generation begins.

In power station the generator is kept to generate electricity and at night generator is used to pump water into high level reservor.At last the electricity reached to power lines and distributed to national Grid.It is clear that at day electricity generated and at night the pumping of water is Do

Task Achievement / Task Response — Band 5.0

The response addresses the task by describing the process of electricity generation, but it lacks a clear overview of the main features. The description of the process is somewhat repetitive and lacks precision regarding the stages shown in the diagram. For instance, the distinction between the 'day' and 'night' cycles is mentioned, but the explanation of the mechanical process (water flow, turbine, generator) is underdeveloped. To improve, you should provide a clear summary of the overall process in the introduction and ensure each stage is described logically and accurately without unnecessary repetition.

Coherence and Cohesion — Band 5.0

The essay is divided into paragraphs, but the logical progression is weak. The introduction is repetitive, and the transition between the 'day' and 'night' cycles is disjointed. Cohesive devices are used in a very limited and sometimes mechanical way, such as 'At last' and 'In the diagram'. There is a lack of variety in linking words, which makes the flow of information feel fragmented. To improve, focus on using a wider range of cohesive devices (e.g., 'consequently', 'subsequently', 'in contrast') to connect sentences and ideas more naturally.

Lexical Resource — Band 5.0

The vocabulary is quite limited and repetitive. You frequently use basic phrases like 'how the electricity is generated' and 'flow of water'. There are also issues with word choice and collocation, such as 'high level reservor' (reservoir) and 'distributed to national Grid'. Some terms are used incorrectly, such as 'Do' at the end of the text, which is incomplete. To reach a higher band, you need to use more precise technical vocabulary related to the process, such as 'turbine', 'intake', 'power lines', and 'pumped storage'.

Grammatical Range and Accuracy — Band 5.0

The response contains frequent grammatical errors that occasionally impede clarity. There are issues with article usage ('the electricity', 'the dam'), subject-verb agreement ('there is several process'), and sentence structure. Many sentences are simple or contain errors in word order, such as 'the generator is kept to generate electricity'. Punctuation is also inconsistent, with missing spaces after periods. To improve, focus on mastering basic sentence structures and proofreading for common errors like missing articles and incorrect verb forms.
