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 diagram provide the information about electricity in a hydroelectric power station.

Overall, it is clear that a river water collect through the dam and there is a intake way that open in day time, however close at night time. Moreover there is a large pipe flow of water go to the generater and perduce electricty. Along with this, power send to national grid the help of power lines.

On the other hand, water reversible from turbines and there are two genretor, one operate generetor and second pump water into high-level reservoir. At the end, a day pipe and a night pipe attected into low-level aera.

To summarise the information by selecting and reporting the main features, and comparise the relevant. It is a huge dam which built on the river to perduce the power and reserved into national grid. Moreover, that power sent to the cities through the power lines.

Task Achievement / Task Response: Band 5.0

You identify the main components—reservoir, dam, intake, turbines, generator, power lines and national grid—and note that the intake is open by day and closed at night. However, the process is only partly described and several details are inaccurate: the diagram shows one generator, not “two genretor”; the turbines operate the generator during the day and pump water back to the high-level reservoir at night. The low-level reservoir is also important to the cycle, but its role is not clearly explained. The final reference to power being sent to cities is not shown. The response is 140 words, below the required 150, and the repeated summary does not add useful process information. Explain the complete day-and-night cycle accurately.

Coherence and Cohesion: Band 4.5

There is some paragraphing and a basic attempt to introduce the diagram, give an overview and describe further details. However, the progression is difficult to follow because the stages are not presented in a clear sequence, and the final paragraph repeats earlier points rather than completing the process description. Connectors such as “Moreover,” “On the other hand,” and “At the end” do not always show the relationship between the ideas that follow them. For example, the shift from the turbines to “two genretor” introduces an inaccurate and confusing contrast. Organise the response into a brief overview followed by a chronological account of daytime generation and nighttime pumping, using clear references to each reservoir.

Lexical Resource: Band 5.0

You use some relevant process vocabulary, including “dam,” “intake,” “turbines,” “power lines” and “national grid,” so the topic is generally recognisable. However, the range is limited and several word-choice, word-form and spelling errors make parts difficult to understand: “river water collect,” “water reversible,” “perduce,” “genretor” and “attected.” Some combinations are also unnatural, such as “a large pipe flow of water go to the generater” and “reserved into national grid.” Use precise process terms and standard spelling, and avoid repeating “power” where a more specific noun such as “electricity” or “water flow” is intended. More accurate collocations would make the description clearer.

Grammatical Range and Accuracy: Band 4.5

The response attempts both simple and longer sentences, including a contrast with “however” and a clause beginning “which built on the river.” However, control is inconsistent, and errors in sentence structure, verb forms, agreement and articles frequently affect clarity. Examples include “The diagram provide,” “a river water collect,” “there is a intake way that open,” and “which built on the river.” The sentence beginning “Moreover there is a large pipe flow of water go…” combines clauses without a workable grammatical structure. Use a reliable present-simple pattern for each stage—for example, subject + verb + object—and check singular/plural agreement and articles. A few accurate complex sentences can then add variety without making the process harder to follow.
