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 illustration represents the process of how electricity is generated through a hydroelectric power station

Overall the process consists of several stages. River water is flowed through different stages to produce electricity.

In the beginning the river water is passed through a dam the purpose of dam is different in day moreover different at night in the morning the water is passed from dam and at night they save the water like they restore it for the other day so they can reuse it again later. After it crosses from a turbine Although the turbines are not normal turbines they are reversible turbines so they could consume it differently at night and different at night.

The turbines acts like a operate generator in the morning on the other hand at night it pump water into high level reservoir. moreover the water from the dam are at high speed as it touches the turbines withe a great speed it makes the fan or motor rotates as in result the electricity gets generated

Task Achievement / Task Response: Band 5.0

You identify the subject and give a basic overview that water is used to generate electricity and can be reused. You also mention the key day/night contrast: the turbines operate the generator during the day and pump water back at night. However, the account only partially covers the process. It does not clearly explain the route from the high-level reservoir through the intake and turbines to the low-level reservoir, or the generator’s connection to the power lines and national grid. Some details are unclear or inaccurate, such as saying the water passes “through a dam” and describing it as moving at “high speed.” To improve, report the stages in order and distinguish the daytime flow from the reverse nighttime pumping cycle.

Coherence and Cohesion: Band 4.5

There is a basic attempt to organise the response, with an opening, an overview, and a description of the process. Time markers such as “In the beginning,” “at night,” and “on the other hand” also show an effort to connect ideas. However, the progression is difficult to follow because several stages are compressed into long, loosely connected sentences. For example, the sentence beginning “In the beginning the river water…” moves between the dam, daytime flow, and nighttime storage without clearly separating them. The final explanation repeats the day/night contrast rather than completing the sequence. Use separate paragraphs for the overview and process details, and connect each stage in chronological order with clear references to where the water moves.

Lexical Resource: Band 5.0

You use some relevant process vocabulary, including “hydroelectric power station,” “reversible turbines,” “generator,” and “high level reservoir,” so the topic is recognisable. However, the range is limited and several choices are imprecise or repetitive, which sometimes makes the process hard to understand. “The river water is passed through a dam” does not accurately describe the route, while “consume it differently” is unclear in this context. The phrase “fan or motor” is also an imprecise description of the equipment shown. Aim for accurate process verbs and technical nouns, such as water flowing through an intake, driving turbines, and being pumped back to the upper reservoir. Avoid repeating “different” when a precise contrast can be stated.

Grammatical Range and Accuracy: Band 5.0

You attempt both simple and more complex sentences, including a contrast with “on the other hand” and a cause-and-result explanation. However, the range is limited, and errors are frequent enough to make some relationships difficult to follow. Examples include “the turbines acts,” where the subject and verb do not agree, and “at night it pump water,” which has an incorrect verb form. The sentence beginning “In the beginning” also runs on without clear punctuation, and “After it crosses from a turbine Although…” contains an incomplete, poorly joined structure. Practise building shorter, complete sentences first, then combine them accurately using clauses. Check subject–verb agreement, articles, and punctuation when describing each stage.
