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 4.5)

The diagram represented how to make the electricity is generated in a hydroelectric power station.frist of all at the above the river make a dam, because here the level of water is high reservoir than make the way for the flow of water to generate electricity. water has been move the generator and make power all this process occurs only in aday after that power move from the power station by the power line.The last stage from the power station power are converted to the differet cities and villages for use for different purposes.This electricity has been used in offices, buildings,tran station and education aidea

Task Achievement / Task Response: Band 3.5

The response identifies the general subject as electricity generation in a hydroelectric station and mentions a river, dam, water flow, generator and power lines. However, it gives only a partial and sometimes inaccurate account: it does not explain the low-level reservoir or the crucial night-time reversal, when water is pumped back uphill, and it adds unsupported claims about electricity being distributed to cities, villages, offices and schools. There is no clear overview of the two operating modes. The response is also 98 words, below the required 150 words, which limits the detail available to describe the process. To improve, summarise the complete day and night cycles and include only information shown in the diagram.

Coherence and Cohesion: Band 4.5

There is a basic attempt to put events in sequence, using “first of all,” “after that” and “the last stage.” This gives the reader some sense of progression, and the response stays broadly focused on the process. However, the stages are crowded into one long, poorly punctuated paragraph, so the relationships between them are difficult to follow. For example, “water has been move the generator” does not clearly connect the water flow to the turbines and generator, while the final sentences shift to uses of electricity rather than continuing the diagram’s sequence. Organise the response into a short introduction, an overview and logically grouped process stages; use clear links for the daytime and night-time cycles.

Lexical Resource: Band 4.5

The response uses some relevant topic vocabulary, including “river,” “dam,” “reservoir,” “generator” and “power line,” so the reader can recognise the general subject. However, the range is limited, and several word choices or combinations are inaccurate or unclear, such as “make the electricity,” “make the way for the flow” and “power are converted to the differet cities.” Spelling errors, including “frist,” “differet” and “tran station,” also reduce clarity. Some details, such as “education aidea,” are difficult to interpret and are not needed for this diagram. Build a more precise process vocabulary, using terms such as “flow,” “turbine,” “transmit” and “reservoir,” and check spelling and collocations.

Grammatical Range and Accuracy: Band 4.5

The response attempts to connect ideas with clauses and time expressions, but sentence structures are mostly simple or incomplete, and errors frequently make the process difficult to understand. Examples include “The diagram represented how to make the electricity is generated,” which combines incompatible verb patterns, and “water has been move the generator,” which has an incorrect verb form and unclear structure. Articles and agreement are also problematic in “at the above the river” and “power are converted.” Punctuation is weak: several sentences run together, and the opening has no space after the full stop. Practise accurate present-simple descriptions of processes, such as “Water flows through the turbines,” and separate each stage into complete, correctly punctuated sentences.
