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 diagram illustrates the information about the how geothermal energy is utilized to generate the electricity.

Overall, it is clear seen that there are several steps which is starting from cold water and ending with generator and turbine for to produce electricity.

Fatching into detail, firstly cold water which is store in a tank pumped down in the rang of 4.5 km. Then after with the help of injuction well all the cold water transfer to the Geothermal zone(hot rocks).

turning toward remaining detail, the production well pumped all the hot water and then hot water stored into the condenser. Remarakbly, with the help of condenser the steam was produce. In last second step, in turbine the steam generate the electricity with the assist of generator and then the electricity pass convert into Geothermal power plant.

Task Achievement / Task Response: Band 5.5

You identify the process as geothermal electricity production and include several relevant stages: cold water is sent underground, heated by hot rocks, and brought back up before steam is produced. However, the account is only partial and the overview is unclear: “ending with generator and turbine” does not accurately summarise the final sequence, and the generator—not the turbine—produces electricity. The description also misstates the condenser as a place where hot water is stored, and says electricity is converted into a geothermal power plant, which is not shown. The 4.5 km depth is correctly reported. The response is 14 words below the required minimum, and adding the omitted turbine-to-generator sequence and a clearer overview would help develop the main features.

Coherence and Cohesion: Band 5.5

There is a basic attempt to organise the response, with an opening, an overview, and phrases such as “firstly” and “turning toward remaining detail” to signal stages. The reader can follow the broad movement from cold water to hot water and steam. However, progression is not consistently clear: “In last second step” is confusing, and the final sentence combines the turbine, generator, electricity, and power plant without showing their relationships accurately. Some transitions sound formulaic rather than helping the sequence, while the paragraphing does not clearly separate the overview from the detailed stages. Use a simple chronological structure and connect each stage explicitly—for example, steam drives the turbine, which in turn powers the generator.

Lexical Resource: Band 5.5

The response uses some relevant process vocabulary, including “injection well,” “production well,” “Geothermal zone,” “condenser,” and “steam,” so the topic is generally recognisable. However, the range is limited and several word choices or collocations are inaccurate, sometimes making the process difficult to understand. For example, “the hot water stored into the condenser” does not describe the diagram, and “electricity pass convert into Geothermal power plant” is unclear. There are also noticeable spelling errors, including “Fatching,” “injuction,” and “Remarakbly.” Aim for precise process verbs and check spelling; terms such as “is pumped,” “is heated,” “is converted into steam,” and “drives” would describe the stages more naturally.

Grammatical Range and Accuracy: Band 5.0

You attempt both simple and longer sentences, but the range is limited and complex constructions are often faulty. Errors occur in verb forms and agreement, as in “there are several steps which is starting,” “cold water which is store,” and “the steam was produce.” Articles and sentence patterns are also problematic in “generate the electricity” and “with the help of injuction well all the cold water transfer.” These errors sometimes make the relationships between stages unclear. Work first on forming accurate passive sentences, which are useful for process descriptions: “Cold water is pumped down the injection well,” followed by “It is heated by the hot rocks.” Use full stops to separate stages and check subject–verb agreement.
