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 5.0)

The given man made process chart represents production of electricity by geothermal energy

Overall it is crystal clear that it is exactly 5 steps to complete the process . To commence with cold water and end with production of electricity by generator .

The first step is cold water pumped into earth crust approximately in 4.5 km in depth which followed by the injection of wall the cold water comes in contact with hot rock and water get heated . Then the hot water is pumped to surface of earth .

moving ahead in last second step in condenser steam is transfer into the turbine .At the last step steam rotated the turbine and powered transfer to generator after that generator produced the energy then electricity are used for different purpose . Then these step start from the initial stage .

Task Achievement / Task Response — Band 5.0

The response fails to meet the minimum word count requirement of 150 words, which significantly impacts the task achievement score. While the main features of the geothermal process are identified, the description is somewhat superficial. The explanation of the steps is brief and lacks the necessary detail to fully convey the process shown in the diagram. For instance, the transition between the condenser and the turbine is unclear, and the explanation of how the generator produces electricity is overly simplistic. To improve, you should aim to expand on the technical details of each stage and ensure the response meets the length requirement to allow for a more comprehensive overview.

Coherence and Cohesion — Band 5.0

The response is organized into paragraphs, but the logical flow is hindered by awkward transitions and repetitive sentence structures. Phrases like 'moving ahead in last second step' and 'at the last step' are mechanical and do not effectively guide the reader through the process. The use of cohesive devices is limited and sometimes inaccurate, which disrupts the progression of ideas. To improve, focus on using a wider variety of linking words and phrases to connect the stages of the process more naturally, such as 'subsequently,' 'following this,' or 'once the steam has been generated.'

Lexical Resource — Band 5.0

The vocabulary is basic and repetitive, relying heavily on simple verbs like 'pumped' and 'get'. There are also issues with word choice and collocation, such as 'man made process chart' instead of 'diagram' or 'flow chart', and 'powered transfer to generator' which is grammatically and lexically unclear. The range of vocabulary is insufficient to describe a technical process with precision. To improve, incorporate more specific terminology related to energy production, such as 'harnessing,' 'thermal energy,' 'pressurized,' and 'conversion,' and ensure that words are used in their correct collocations.

Grammatical Range and Accuracy — Band 5.0

The response contains frequent grammatical errors that occasionally impede clarity. Examples include 'it is exactly 5 steps' (should be 'there are'), 'approximately in 4.5 km in depth' (preposition error), and 'electricity are used' (subject-verb agreement error). The sentence structures are mostly simple, and attempts at complex sentences are often faulty or poorly punctuated. There is a lack of variety in grammatical structures, which limits the ability to express the process clearly. Focusing on subject-verb agreement, correct preposition usage, and the use of passive voice—which is essential for process descriptions—would greatly improve your score.
