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 6.0)

The following diagram depicts the method to generate the electricity with the help of geothermal energy.

Overall,this process consists of five stages,started from cold water and finalize at generator and turbine to produce elecric current.

we clearly seen that this process starts from cold water.Cold water pumped down to the Earth with the depth of 4.5 km.In second step the injection wall installed there after this water passes through the hot rocks where cold water converts into the hot water.After the second step,the production well pumped up the hot water and hot water transfers to the condenser chamber.

Moreover,in fourth stage hot water changes into the steam with the help of condenser chamber.After this stage steam is use for rotate the turbine with high speed.At the final stage,turbine rotates speedly and produce electricity with the generator.After all these stages electricity produced with the water and supply to the poles of electricity.

Task Achievement / Task Response: Band 6.5

You cover the main sequence from cold water being pumped underground to electricity generation, and include the important depth of 4.5 km. The overview also recognises that the process has stages, while details such as the injection and production wells, hot rocks, condenser, steam, turbine and generator are relevant. This gives the account a clear basis in the diagram. However, the overview is not fully accurate: the process does not finish at the generator and turbine, and the turbine does not itself produce electricity; it drives the generator. The final reference to electricity being supplied to “poles” is also imprecise. To strengthen the response, give a concise, accurate overview of the complete transformation and clarify the roles of the turbine and generator.

Coherence and Cohesion: Band 6.5

The response is arranged in a generally logical order, moving from the initial water supply through underground heating and then to electricity generation. Paragraph breaks help distinguish the overview from the process details, and markers such as “Moreover,” “After this stage” and “At the final stage” make the sequence easy to follow. This provides coherent overall organisation. Some linking is mechanical or unclear, however: “After the second step” does not clearly identify the next stage, and “After all these stages” adds little to the conclusion. The overview also says the process ends at the generator and turbine, which conflicts with the later account. Use stage references consistently and connect each step directly to the next to make progression more precise.

Lexical Resource: Band 5.5

You use relevant process vocabulary, including “injection well,” “production well,” “condenser,” “steam” and “geothermal energy,” so the reader can identify the main components. There is also some attempt to describe movement and transformation, for example, water “pumped down” and then “converts into the hot water.” However, several word choices and collocations are inaccurate or awkward, such as “generate the electricity,” “rotate the turbine with high speed,” and “supply to the poles of electricity.” Spelling errors in “elecric” and “speedly” also reduce precision. Aim for standard process-reporting phrases and accurate technical terms; this will make the description clearer without requiring more elaborate vocabulary.

Grammatical Range and Accuracy: Band 5.0

The response attempts both simple statements and longer sequences, including “After this stage steam is use for rotate the turbine,” but control of sentence structure and verb forms is limited. Errors include “this process consists of five stages, started,” “we clearly seen,” and “steam is use,” where tense, participle or verb-form choices are faulty. Articles and sentence boundaries also need attention: “with the depth of 4.5 km” and the missing space after full stops make parts less polished. These errors sometimes make relationships between actions harder to follow, although the overall process remains understandable. Practise accurate present-simple passive forms for processes, such as “water is pumped” and “steam is used,” and check each sentence for a complete, correctly formed verb.
