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 process of producing electricity from geothermal energy.

overall,electricity os produced through several stages, begining with the cold water and ending with the generator turbine.

First,cold water is used in this process.and this water is pumped down into the injection well.the ditsnace from cold water to injection well is 4.5km.When cold water is reached into the injection well Now the second process is start.This cold water in injection well is going through another process which is geothermal zone.In this act cold water now becomes a hot rocks.

Next it is the production well.In this well hot water which has gone through geothermal zone is now pumped up.This hot water is reaching to the condenser.Moreover,steam is being produce through the condenser.

This steam is now mixed into the turbine.The turbine is powered by the steam.

and the last atep is generator which is powered by turbine and generate electricity .this is whole scenarioe of geothermal power plant.how the electicity is produced in power plant.

Task Achievement / Task Response: Band 5.5

You identify the process and describe its main sequence: cold water enters the injection well, passes through the geothermal zone, rises through the production well, and is converted to steam before powering a turbine and generator. However, some key details are unclear or inaccurate. The water does not become “hot rocks”; it is heated by the hot rocks. The 4.5 km measurement refers to the depth of the well, not the distance “from cold water to injection well.” The overview also says the process ends with the “generator turbine,” which confuses two separate components. To make the summary more complete and precise, state clearly that the generator produces electricity and include the overall transformation from cold water to electricity.

Coherence and Cohesion: Band 5.5

The response follows the diagram’s general order, and sequencing words such as “First,” “Next,” and “the last step” help the reader follow the stages. However, progression is weakened by unclear links and sentence boundaries. For example, “When cold water is reached into the injection well Now the second process is start” is difficult to follow, while “and the last atep” begins a new stage without appropriate sentence control. Several ideas are also repeated, particularly the statements about steam powering the turbine and the generator being powered by it. Organise the description into a brief overview and clearly separated stages, and use linking phrases to show cause and movement rather than relying mainly on basic sequence markers.

Lexical Resource: Band 5.0

You use relevant process vocabulary, including “injection well,” “production well,” “geothermal zone,” “condenser,” and “turbine,” which allows the reader to recognise the main components. However, the range is limited and several word choices or forms are inaccurate enough to make parts of the process unclear. “Cold water now becomes a hot rocks” misrepresents the change, and “steam is being produce” and “this steam is now mixed into the turbine” are not natural descriptions of the process. Spelling errors such as “ditsnace,” “scenarioe,” and “electicity” also reduce clarity. Build a more precise set of process verbs, such as “heat,” “rise,” “convert,” and “drive,” and check spelling and word forms.

Grammatical Range and Accuracy: Band 5.0

The response attempts to describe a sequence using both simple sentences and longer clauses, but control is inconsistent. Errors in verb forms and sentence construction occur frequently, as in “the second process is start,” “steam is being produce,” and “the generator … generate electricity.” Some sentences run together or lack clear punctuation, particularly “When cold water is reached into the injection well Now the second process is start.” Capitalisation is also inconsistent after full stops, as in “and the last atep.” These problems sometimes make relationships between stages difficult to understand. Practise forming accurate passive constructions for process descriptions—for example, “water is pumped down” and “steam is produced”—and check subject–verb agreement and sentence boundaries.
