IELTS Writing Task 1 question

The diagram below shows how geothermal energy is used to produce electricity.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

Student answer (Band 5.5)

The process chart depicts the procedure how geothermal energy is utilized to manufacture electricity.

To initiate with, firstly, cold water is pumped down to injection well which is 4.5 km under the ground. Afterthat, the water is passes through geothermal zone whic contain hot rocks.Moreover, after crossing two steps hot water is produce and travelling through the production well. The water is pumped to upwars for other crucial steps.

Probing ahead, there is a condensar producing stream from warm water with the help of vapours. Moving further, stean is going through turbine with rotating motion. After passes from turbine a generator is placed with is powered by turbine and it provide electricity to towers for the household utilization

Overall, all the steps are vital to produce electricity. However if any step is left the procedure take on hold and not able to produce electric current for the usage of the people

Task Achievement / Task Response — Band 5.5

The response covers the main stages of the geothermal energy production process, from the injection well to the distribution of electricity. However, the description is somewhat superficial. While the key steps are identified, the explanation lacks the precision required for a higher band. For instance, the mention of 'two steps' is vague and does not accurately reflect the technical nature of the diagram. The overview provided in the final paragraph is more of a general observation than a summary of the main features or trends. To improve, ensure that the relationship between the components is described more clearly and accurately.

Coherence and Cohesion — Band 5.5

The essay is organised into paragraphs, which helps the reader follow the progression of the process. However, the use of cohesive devices is often mechanical or inaccurate. Phrases like 'To initiate with' and 'Probing ahead' are not standard academic transitions. Referencing is sometimes unclear, such as in the sentence 'After passes from turbine a generator is placed with is powered by turbine', where the connection between the components is muddled. The flow between sentences is occasionally disjointed, making the overall progression feel slightly forced rather than natural.

Lexical Resource — Band 5.0

The vocabulary is limited and contains several errors that occasionally impede clarity. There are frequent spelling mistakes, such as 'condensar' for condenser, 'stean' for steam, and 'upwars' for upwards. Word choice is also imprecise; for example, 'manufacture electricity' is not a standard collocation, as electricity is 'generated' or 'produced'. While the student attempts to use technical terms related to the diagram, the lack of control over basic spelling and collocation prevents the response from reaching a higher band. A wider range of precise, topic-specific vocabulary is needed.

Grammatical Range and Accuracy — Band 5.0

The response relies on a mix of simple and attempted complex sentences, but the accuracy is low. There are frequent errors in verb forms and sentence structure, such as 'the water is passes', 'hot water is produce', and 'which contain hot rocks'. Punctuation is also inconsistent, with missing commas and incorrect sentence boundaries. The misuse of relative clauses ('which is powered by turbine and it provide') further complicates the reading. While the meaning is generally understandable, the high frequency of grammatical errors significantly impacts the quality of the writing.
