Student answer (Band 5.0)
Writing task 1
The diagram outline the stages of how electricity is generated in a hydropower electic power station.
In the first step the water of river can be stored in the dam. Excessive amount of water is collected to generate the electricity. Further a small canal is made where water is flowing during the day time and reached to the power station. when water gathered in a turbine the generator started and by the support of national grid power lines the turbines moved and electricity is produced. All this process is happened during the day time.
Despite this at the second step at night this process is stopped. All the water that is remaining
during the morning task stored in the low level reservor and when night comes the power lines become off and water is moving to the high reservor through the same canal where in morning water is fleet flowing. This proce Although this process remains the same everyday to make the electricity that is used in our industrial areas, and housing etc.

Task Achievement / Task Response — Band 5.0
The response covers the main stages of the hydroelectric process, but the description is somewhat disjointed and lacks a clear overview. While you identify the day and night cycles, the explanation of the mechanism is confusing. For instance, stating that 'the generator started and by the support of national grid power lines the turbines moved' is technically inaccurate, as the turbine movement drives the generator, not the other way around. The summary of the process is incomplete, and the final sentence is fragmented, which hinders the overall clarity of the report. To improve, ensure you clearly distinguish between the high and low reservoirs and describe the flow of water more accurately.
Coherence and Cohesion — Band 5.0
The response is divided into paragraphs, but the logical flow is weak. The transition between the day and night cycles is abrupt, and the use of cohesive devices is limited and sometimes misused, such as 'Despite this at the second step'. The final sentence is incomplete, which creates a significant break in the progression of ideas. To improve, use clearer linking words to show the relationship between the stages (e.g., 'consequently', 'subsequently', 'in contrast') and ensure that each sentence is complete to maintain the flow of information.
Lexical Resource — Band 5.0
The vocabulary is generally basic and sometimes inaccurate. You use terms like 'fleet flowing' and 'power lines become off', which are not standard collocations. There are also spelling errors such as 'electic' and 'reservor'. While you attempt to describe a technical process, the lack of precise terminology (e.g., 'intake', 'penstock', 'discharge') limits your ability to convey the information effectively. To reach a higher band, focus on learning topic-specific vocabulary related to diagrams and processes, and pay closer attention to word choice and spelling.
Grammatical Range and Accuracy — Band 5.0
The response contains frequent grammatical errors that occasionally impede communication. There are issues with subject-verb agreement ('the generator started', 'turbines moved'), article usage ('the water of river'), and sentence structure. Many sentences are simple or contain errors in tense and word order. The final sentence is a fragment, which is a major grammatical error. To improve, practice basic sentence construction and proofread your work to ensure that every sentence has a clear subject and verb and that your tenses are consistent throughout the report.
