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 diagram given below illustrate the process of producing electricity from cold water through several steps.

overall, there are 5steps involved and 3stages beginning with cold water and middle steps are involved for producing the electricity using the cold water and ending with the generated electricity by the generator.

Intially the cold water is filled in container then it is pumped down to the injection well which is 4.5 km depth and later this water is sent to the production well while the water reaching the production well it goes through geothermal zone where the water gets hot while passing through this geothermal zone.

From the production well the hot water is pumped up to the condenser where the hot water is converted into steam. that steam is passed to the turbine where the power is generated using the steam and this power is sent to the generator which is powered by turbine and produces the electricity.

Task Achievement / Task Response: Band 6.0

You describe the main sequence from cold water being pumped underground to electricity being produced, and you include the important 4.5 km depth. The overview also identifies the process as a series of stages, so the response addresses the task. However, some details are unclear or inaccurate: the water is heated as it passes through the geothermal zone before it rises in the production well, whereas your wording first says it is sent to that well and then describes the heating. The final stages are also blurred: the turbine is driven by steam, and it drives the generator; electricity is produced by the generator, not by the turbine. Make the overview more precise and report each stage in its correct order to develop the description more fully.

Coherence and Cohesion: Band 6.5

The response follows a generally logical process order, moving from the cold-water container through the underground wells and then to the condenser, turbine and generator. The opening overview and the use of sequence markers such as “then,” “later” and “From the production well” help the reader follow the explanation. This gives the response a coherent overall arrangement. However, the account is presented as one continuous block, and some links are awkward or unclear, particularly “while the water reaching the production well it goes through geothermal zone.” The overview’s reference to “5steps” and “3stages” is also not clearly connected to the later description. Use separate paragraphs for the overview and process details, and make transitions express the sequence and cause more precisely.

Lexical Resource: Band 5.5

You use relevant process vocabulary, including “injection well,” “production well,” “geothermal zone,” “condenser,” “steam” and “turbine,” which allows you to identify the main components. There is also some useful variation in describing movement, such as “pumped down” and “pumped up.” However, several phrases are imprecise or repetitive: “the power is generated using the steam” does not clearly distinguish the turbine’s role from the generator’s, and “the process of producing electricity from cold water” is less exact than describing geothermal energy. Spelling and word-form slips such as “Intially” and “5steps” also reduce accuracy. Choose precise process verbs and check spelling and spacing to make the description more natural.

Grammatical Range and Accuracy: Band 5.0

You attempt both simple and more complex sentences, including a relative clause in “the injection well which is 4.5 km depth” and a time clause beginning “while.” The overall meaning is usually recoverable, but some errors in sentence structure, agreement, articles and punctuation make parts difficult to read. For example, “The diagram given below illustrate” has a subject–verb agreement error, while “while the water reaching the production well it goes through” is not a complete, correctly formed clause. Capitalisation after full stops is inconsistent, and several long sentences need clearer punctuation. Practise forming complete clauses and use shorter sentences where necessary; this will improve accuracy while retaining your attempts at complex structures.
