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)

The given diagram illustrates that the generation of electricity with the help of hydroelectric power station.

Firstly, a lagre amount of water is stored in the Dam coming from the river.Likely the dam is opened at day time and close at night.Afterwards there is a Power station for making electricity.

Moreover,the whole process of generating current along the reversible turbines in this section current generated and then moved to the next destination that is power lines.

To sum it up, the all process of the creating electric current through the water that is comming from the river is disscused in this described diagram.

AI examiner evaluation

Task Achievement / Task Response: Band 4.0

You identify the general subject—electricity generation in a hydroelectric station—and mention the river, dam, turbines and power lines. However, the account is only a minimal response to the process: it does not explain the main sequence or the important day/night cycle, including water passing through the turbines to the low-level reservoir by day and being pumped back at night. The statement that “the dam is opened” is also inaccurate; the diagram labels an intake that is open by day and closed at night. There is no clear overview of how the system operates, and several stages are omitted or unclear. The response is also 47 words below the required minimum. To improve, describe the complete cycle in order and include its key operating contrast.

Coherence and Cohesion: Band 5.0

The response has a basic sequence, signalled by “Firstly,” “Afterwards,” “Moreover” and “To sum it up,” and it stays broadly focused on the diagram. These markers provide some organisation, but the progression is not clear because important stages are skipped and the links between ideas are weak. For example, “Afterwards there is a Power station for making electricity” does not explain how water reaches the station or how the generator and turbines work together. The final sentence repeats the general topic rather than summarising the process. Use separate paragraphs for an overview and the stages, then connect each stage with precise references such as “the water then flows” and “at night, it is pumped back.”

Lexical Resource: Band 5.0

You use some relevant process vocabulary, including “reversible turbines,” “power lines,” “river” and “electricity,” so the reader can recognise the topic. However, the range is limited and several choices are inaccurate or awkward, which makes parts of the description difficult to interpret. “Current” is repeated instead of using more precise terms such as “electricity” or “electrical power,” while “the next destination” is vague for describing the route to the national grid. Spelling errors such as “lagre,” “comming” and “disscused” also reduce accuracy. Build a small bank of process verbs and technical nouns, and check spelling and collocations before finishing.

Grammatical Range and Accuracy: Band 5.0

You attempt both simple statements and longer sentences, but the range is limited and errors recur. The opening, “The given diagram illustrates that the generation of electricity…,” has an awkward clause structure; a direct form such as “The diagram illustrates how electricity is generated” would be clearer. In “the dam is opened at day time and close at night,” the verb forms are not parallel, and the sentence also misidentifies the intake as the part that opens and closes. Missing spaces after full stops and commas, as in “river.Likely” and “Moreover,the,” further affect readability. Practise accurate passive forms and consistent verb structures, and proofread sentence boundaries and punctuation.
