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 supplied process diagram shows the Geothermal power plant which is providing full process of producing electricity.

First and moreover the process starts from cold water which is pushed down in basement which is 4.5 dig and than its forwarded through geothermal zone where hot rocks makes the water hot. The hot water is pulled back from next dig which is called production well and than there is condenser which pulls steam of water and gives to the genrator turbine.

Secondaly there is a turbine which is powered by steam that is supplied from basement and than it transfers that power to genrator which is the main production of electricity , it is powered by turbine and last stage of process.

The lastest part of process genrator which produce electricity and supplies to the tower from where the whole city and each houses gets the electricity.

Task Achievement / Task Response: Band 4.5

You identify the main stages: cold water is sent underground, heated by hot rocks, returned through the production well, and used to generate electricity. However, the account is incomplete and sometimes inaccurate. The diagram shows water entering a condenser, where it becomes steam; the steam then powers a turbine, which drives the generator. Your phrase “condenser which pulls steam of water and gives to the genrator turbine” blurs these separate stages. The claim that electricity is supplied to “the whole city and each houses” is not shown; the diagram only indicates transmission via a pylon. The response is also four words below the required minimum. Add a clear overview and describe each stage accurately and in sufficient detail.

Coherence and Cohesion: Band 5.5

The response has a basic sequence, moving from water being pumped down to electricity being transmitted, and the paragraphs broadly separate the underground process from the machinery. However, progression is not consistently clear: “First and moreover,” “Secondaly,” and “The lastest part” are awkward or repetitive signposts, and the final paragraph repeats the generator’s role rather than adding a distinct stage. Some links between steps are unclear, particularly the sentence about the condenser and turbine. Organise the description into a brief overview followed by the stages in order, using precise links such as “Next,” “Once heated,” and “Finally.” This would make the sequence easier to follow without relying on mechanical transitions.

Lexical Resource: Band 5.0

You use some relevant process vocabulary, including “geothermal zone,” “production well,” “condenser,” “turbine,” and “generator,” so the reader can recognise the topic. However, the range is limited and several word choices or forms are inaccurate, sometimes making the process difficult to understand. For example, “4.5 dig” does not clearly express the depth, “pulled back” is imprecise for water rising through the well, and “pulls steam of water” is not a natural description of steam production. There are also noticeable spelling errors, including “genrator,” “Secondaly,” and “lastest.” Use accurate process verbs and check spelling; for example, say water is “pumped down,” “heated,” and “pumped back up.”

Grammatical Range and Accuracy: Band 5.0

You attempt to connect stages in longer sentences using “which,” “where,” and “than,” but these complex structures are often faulty, and sentence control is inconsistent. For instance, “hot rocks makes the water hot” has a subject–verb agreement error, while “the process starts from cold water which is pushed down in basement” has problems with articles and sentence construction. The sentence beginning “there is condenser” also lacks an article, and the comma splice in “electricity , it is powered by turbine” makes the relationship between clauses unclear. Most sentences rely on a similar pattern, so the range remains limited. Practise accurate simple sentences first, then combine stages with controlled clauses and correct punctuation.
