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 6.0)

The diagram illustrates the process of generating electricity in a hydroelectric power station.

Overall, The process is performed during the day and to execute this various preparation are done during the previous night.

Before starting the process river water is being halt in a High level reservoir inside of a dam. To Begin the process thee doors of the dam are open.

after opening the doors the rushing water flows at very high speed towards power station. This water help to spin the turbines connected to a genrator. continuous spinning of the turbines finally genrates electricity which is transferred to national grid via power lines. The remaining water is then stored at low level reservoir

Once the electricity is genrated, the water inside the low level reservoir is pumped using the same turbines which are reversible. moving further to high level reservoir, After all the water is pumped successfully. doors are kept shut of the dam

Task Achievement / Task Response: Band 6.5

You cover the main operating cycle and give a clear overall distinction between daytime electricity generation and nighttime preparation. The account correctly identifies the high-level reservoir, the turbines and generator, transmission to the national grid, and the return of water from the low-level reservoir for pumping back uphill. This is a strong, relevant response, though some details are less fully or precisely explained: for example, the intake is open by day and closed at night, but you refer more generally to “doors of the dam,” which could suggest the dam itself is opened. The nighttime pumping stage is included, but its relationship to the reversible turbines and the closed intake could be stated more clearly. More precise coverage of these labelled stages would strengthen an already effective summary.

Coherence and Cohesion: Band 6.0

The response follows a broadly logical sequence: it introduces the process, describes daytime generation, and then explains the nighttime return of water. Paragraphing also separates the overview from the process details. However, progression is sometimes weakened by abrupt transitions and unclear links, particularly in “Once the electricity is generated” and “moving further to high level reservoir, After all the water is pumped successfully.” The sequence would be easier to follow if each stage were connected with precise time markers such as “During the day,” “After passing through the turbines,” and “At night.” Some linking is mechanical, and inconsistent sentence boundaries and capitalization distract from the otherwise coherent arrangement.

Lexical Resource: Band 5.5

You use relevant process vocabulary, including “reservoir,” “turbines,” “generator,” “pumped,” and “national grid,” which allows the reader to understand the main stages. There are also attempts at more descriptive wording, such as “rushing water” and “continuous spinning.” However, several word choices or collocations are imprecise: “water is being halt” does not naturally describe storage, and “doors of the dam” is less accurate than “intake gates.” Spelling errors such as “genrator” and “genrates” are noticeable, while repeated use of “water” and “process” limits flexibility. Aim for accurate technical terms and natural collocations rather than adding descriptive language that is not needed in a process report.

Grammatical Range and Accuracy: Band 5.0

You attempt a mixture of simple and more developed sentences, including the relative clause in “turbines connected to a generator” and the time clause beginning “Once the electricity is generated.” The main sequence remains understandable, but grammatical control is uneven. For example, “This water help to spin” has a subject–verb agreement error, while “Before starting the process river water is being halt” has problems with the verb form and sentence construction. Several sentence fragments or run-ons appear around “moving further to high level reservoir” and “After all the water is pumped successfully.” Capitalization and punctuation are also inconsistent. Practise forming complete sentences with controlled passive structures, which are especially useful for describing processes.
