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 below image shows how geothermal energy is used to porduce electricity . In this pitucer we see how to use cheap methods to porduce electricity .

First we use cold water send to the earth around 4.5km and injected into hot rocks ,these rocks convert into steam and push on the surface . Then the pumped throw condenser with high pursers.

Second this hot steam go into the turbine to routate high speed and this turbine attached with a large generator ,these generator porduce the electricity and send to the gread station.

Task Achievement / Task Response: Band 4.5

You identify the process as geothermal electricity production and include several relevant stages: cold water is sent underground, heated by hot rocks, and the resulting steam drives a turbine and generator. However, the account is very brief and omits or misrepresents important details. The diagram shows water returning to the surface through a production well before entering a condenser; it does not show the rocks turning into steam underground. The condenser produces steam, and the generator sends electricity to a transmission pylon, not a “gread station.” There is also no clear overview of the process as a whole. The response is 57 words below the required minimum, which limits how fully the stages can be reported. Add a concise overview and describe each stage accurately.

Coherence and Cohesion: Band 5.5

The response has a basic sequence, signalled by “First” and “Second,” and the reader can follow the broad movement from underground water to electricity production. The two short paragraphs also provide some separation between stages. However, the progression is incomplete: the condenser, steam, turbine, and generator are not linked clearly in the correct order, and the second paragraph begins with “this hot steam” without a clear antecedent in the preceding description. Some ideas are joined in long, loosely connected sentences, making the relationships between actions less clear. Organise the account into a clear introduction and overview, followed by stages in sequence, and use precise references such as “the heated water” and “the resulting steam.”

Lexical Resource: Band 4.5

You use some relevant process vocabulary, including “cold water,” “hot rocks,” “condenser,” “turbine,” and “generator,” so the topic is recognisable. However, the range is limited and several inaccurate or misspelled words make the description difficult to interpret, such as “porduce,” “pitucer,” “pursers,” and “gread station.” Some word combinations are also unsuitable: water does not “convert into steam” in the hot rocks in this diagram, and “routate high speed” does not describe the turbine naturally. Use accurate process terms and collocations, for example, say that water is heated underground, pumped to the surface, and converted into steam in the condenser. Proofreading spelling would also improve clarity.

Grammatical Range and Accuracy: Band 5.0

You attempt to connect several actions in longer sentences, for example, “First we use cold water send to the earth … and injected into hot rocks,” but the structures are often incomplete or faulty. The opening also shifts awkwardly between “shows” and “we see,” while “these generator porduce” has a subject–verb agreement error. Articles and sentence boundaries are frequently missing or misplaced, as in “this turbine attached with a large generator,” and commas join independent ideas without clear punctuation. These errors sometimes make the process relationships hard to follow. Practise forming complete passive sentences for process descriptions, such as “Cold water is pumped down the injection well,” and check agreement, articles, and punctuation.
