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)

Here this diagram about how geothermal energy is used to produce electricity and definately there are different steps in diagram we can see.Let's discuss how geothermal energy is using to produce electricity.

Here we can see inside the ground there are two pumps one is left side the seceond is right side the first one is for pump cold water in down it is about 4.5 kilometer down also top of it on ground a tank of cold water and the left one is for pump up hot water to Condenser which is exact on top of ground the right pump.Also in between two pumps we have a connecter name geothermal zone, for this connector two points left one is for the injection well and the right one is for production well.

So, now we move ouside of ground there is one big tower which have one Generator which is powring by turbine and produce electricity and right sideof generator we have Turbine which powring by Steam basically Steam is the connection beween Turbine and Condencer. And finally the most important thing the Generator connected with tower and producing electricity to tower.

Task Achievement / Task Response: Band 5.0

You identify the main stages, including cold water being sent underground, heated in the geothermal zone, and returned to the surface before steam powers the turbine and generator. The 4.5 km depth is also reported accurately. However, the account is only partly effective as a process summary: there is no clear overview of the overall transformation, and some relationships are unclear or inaccurate. For example, you call the geothermal zone a “connector” and describe the generator as connected to a “tower,” rather than clearly explaining that the generator produces electricity and is linked to the transmission pylon. Focus on the key stages and their functions, using precise descriptions rather than adding unclear details.

Coherence and Cohesion: Band 5.5

The response has a basic sequence, moving from the underground wells to the equipment above ground, and phrases such as “So, now we move ouside of ground” signal a change in focus. However, the progression is not consistently clear because the writing is divided into conversational sections rather than a concise process description. Several ideas are crowded into long sentences, especially the paragraph beginning “Here we can see inside the ground,” and references such as “the left one” and “the right pump” make it difficult to track which well is meant. Organise the stages in a clear order and use accurate labels— injection well, production well, condenser, turbine and generator—to make the links between steps easier to follow.

Lexical Resource: Band 5.0

You use some relevant process vocabulary, including “injection well,” “production well,” “geothermal zone,” “condenser,” “turbine” and “steam.” This gives the reader a basic understanding of the diagram. However, the range is limited and several word choices or collocations are inaccurate, which sometimes makes the description difficult to interpret. For instance, “connector” does not describe the geothermal zone, and “powring by” is not an appropriate way to explain how the turbine or generator operates. Spelling errors such as “definately,” “seceond” and “beween” are also noticeable. Learn and use precise process verbs such as “pump,” “heat,” “convert” and “drive,” and check spelling before submitting.

Grammatical Range and Accuracy: Band 5.0

You attempt to connect several stages in longer sentences, but the structures are often faulty, and simple sentence patterns dominate. For example, “Here this diagram about how geothermal energy is used” lacks a main verb, while “there are two pumps one is left side” joins clauses without suitable punctuation or grammatical linking. There are also recurring problems with articles, prepositions and agreement, as in “a tank of cold water” and “Generator which is powring by turbine and produce electricity.” These errors can make the process relationships unclear. Practise writing one complete sentence for each stage, using accurate passive forms such as “Cold water is pumped down” and “Hot water is pumped up,” and check sentence boundaries and verb agreement.
