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)

Electrici ty generates through water in dam's.

First water enters the Dam water pipeline and the pipeline goes to high level reservoir which reserves the water quantity for moving to next procedure.

In the reservation tank, The litle intake of water in the bottom of tank. The intake time is open for day and close at night.

Then water flows through intake and entered the next step which is generator turbine the named power station the generate rotate on high speed with the support of water intake and then the water enters the low-level reservoir at day and then back at night with flow of water pumping at night.

When the electricity generates through this process the generator collect all the electricity and then move forward through power cable lines to National grid station for consuming electricity at public or residential places where electricity is often use that is the process of making electricity through Dam.

Task Achievement / Task Response: Band 5.0

You identify the main components, including the reservoirs, intake, turbines, generator and national grid, and you mention the day/night cycle. However, the process is only partly described and some relationships are unclear or inaccurate. For example, the river feeds the high-level reservoir; the pipeline does not lead to that reservoir as your opening stages suggest. The key contrast—that water flows downhill to generate electricity by day, while the reversible turbines pump it back uphill at night—is not explained clearly. The overview is also missing: state the system’s two-way operation before describing its stages. Focus on the main sequence and explain how the generator and grid fit into daytime generation.

Coherence and Cohesion: Band 5.5

The response generally follows the process from water storage to electricity transmission, and words such as “Then” and “and then” help signal sequence. However, the progression is not consistently clear because several stages are combined in long sentences, especially the sentence beginning “Then water flows through intake.” The day and night operations are also blended together, making it difficult to follow the return flow. Paragraphing would help distinguish an overview from the detailed stages. Use clearer links such as “During the day” and “At night,” and give each stage a distinct place in the sequence. This would make the organisation more coherent and reduce repetition.

Lexical Resource: Band 5.0

You use some relevant process vocabulary, including “high level reservoir,” “intake,” “low-level reservoir,” “generator,” and “National grid.” This gives the reader a basic sense of the subject. However, word choice and collocation are often inaccurate, sometimes making the process difficult to understand: “reservation tank” is not the appropriate term, and “the generator collect all the electricity” does not describe the generator’s function precisely. There are also spelling and form problems, such as “litle” and “Electrici ty.” Build a more accurate set of process terms and use them consistently; for example, describe water as flowing through a conduit and the generator as producing electricity.

Grammatical Range and Accuracy: Band 5.0

You attempt to connect stages using longer sentences, but the range of sentence structures is limited and these attempts often contain errors that affect clarity. For example, “the pipeline goes to high level reservoir which reserves the water quantity” has unclear clause structure, while “the generator collect” has a subject–verb agreement error. Tense and article use are also inconsistent, as in “water enters” followed by “the electricity generates.” Several sentences run on, particularly the description of the turbines, reservoirs and night pumping. Use mostly clear present-simple sentences for the process, check agreement and articles, and separate each stage with full stops. More accurate control of these basics would make your meaning easier to follow.
