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 figure below is showing how we use water to produce an electricity. This is a whole process which contain different steps to produce electrical energy. Overall this is the process in which geothermal energy converted into electrical energy. Following are the steps that are based on to who produce electricity

Firstly, The cold water pumped down towards hot rocks and because of that rocks water converted into steam. This whole process is totally depend upon water cold water become hot and than converted into steam

Secondly, That steam which is made by the help of hot rocks that water vapours are used to run the turbines and when that turbines are powered by the steam than that are used to give power to the generator

Afterall, the power which is stored in generators that help us to produce electricity by this all procedure we used to convert geothermal enerdy into electrical energy

Task Achievement / Task Response: Band 5.0

You identify the overall purpose as converting geothermal energy into electricity and mention the main elements of water, hot rocks, steam, turbines and a generator. However, the account only partially describes the process: it omits the two distinct wells, the 4.5 km depth, and the condenser, which is where the heated water is converted into steam. The claim that water becomes steam because it passes the hot rocks is not precise; the diagram shows hot water being pumped up to the condenser before steam is produced. The final stage is also unclear: electricity is produced by the generator, rather than power being stored in it. A clearer overview and a more accurate, ordered account of each stage would make the response more complete.

Coherence and Cohesion: Band 5.5

The response has a basic sequence, signalled by “Firstly,” “Secondly,” and “Afterall,” and it begins with an introduction and an overall statement. These features help the reader recognise that the process has stages. However, the progression is not consistently clear: the first stage combines pumping water down, heating it, and producing steam, while the condenser and separate wells are not explained. Several sentences repeat the same idea, particularly the conversion of geothermal energy into electrical energy, and references such as “that water vapours” and “that are used” make it difficult to identify what each pronoun refers to. Organise the body into clear stages and use precise links and references to show how each output becomes the next input.

Lexical Resource: Band 5.0

You use relevant process vocabulary, including “cold water,” “hot rocks,” “steam,” “turbines,” “generator,” and “electrical energy,” so the topic is generally recognisable. However, the range is limited and several choices or forms are inaccurate or repetitive, such as “produce an electricity,” “water vapours,” “power which is stored in generators,” and “enerdy.” “Afterall” is also not an appropriate connector in this context. More precise terms from the diagram—such as “injection well,” “production well,” “condenser,” and “electricity is generated”—would help you describe the stages accurately and avoid repeating broad phrases like “produce electricity.”

Grammatical Range and Accuracy: Band 4.5

You attempt some longer sentences using “because,” “when,” and “which,” but these structures are often faulty, and the response relies heavily on similar sentence patterns. For example, “This is a whole process which contain different steps” has an agreement error, while “This whole process is totally depend upon water” has an incorrect verb construction. Capitalisation after “Firstly” and punctuation between ideas are also inconsistent. These errors sometimes make relationships between stages difficult to follow, especially in the long sentence beginning “Secondly.” Practise building accurate simple sentences first, then connect them with clauses—for example, “Cold water is pumped underground, where hot rocks heat it”—and check subject–verb agreement and verb forms.
