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 illustrations shows the process of elcetircity production from the geothermal energy . Overall, electricty is produced form energy when the winds of turbine are moved it produced electricity .

Initially ,the stored cold water is pumped downward 4.5 kilomter towords the injection well right to thr geothermal zone which also called hot rocks then to production well which is pumped up the water is hot as well after all are collected in the condenser which comes out as a steam .

Similarly , these steam are then used by the turbines which is powered by steam as well . After these turbines are moved in the circular motions then it will stored in the generator powered by turbines which such produces electricity which after all this process it automatic connected to electricity supplier

.The main role in the production of electricity is the geothermal energy which first colled as cold water then after processing done moved to turbines which results in powering electricity .

Task Achievement / Task Response: Band 5.5

You identify the main stages, including cold water being pumped underground, heating in the geothermal zone, hot water returning to the surface, and steam driving a turbine and generator. This gives the reader a relevant account of the process. However, the overview is inaccurate: “the winds of turbine” do not produce electricity; rather, steam powers the turbine, which drives the generator. Some stage relationships are also unclear, particularly “after all are collected in the condenser,” and the final connection to an “electricity supplier” is not shown—the diagram shows transmission lines and a pylon. To strengthen the response, give a concise, accurate overview first, then describe the stages in order, including the 4.5-km depth and the conversion from water to steam.

Coherence and Cohesion: Band 5.5

The response follows the broad sequence of the diagram, moving from water injection to heating, steam, and electricity generation. The paragraph breaks also suggest an attempt to separate the overview from the process details. However, progression is weakened by long, loosely connected sentences, such as the sentence beginning “Initially” and continuing through the production well and condenser. Connectors including “Similarly,” “After these,” and “after all” are either imprecise or repetitive, and references such as “these steam” and “it” make it difficult to track the process. Use one clear stage per sentence and link stages with precise sequencing language such as “Next,” “At the surface,” and “Finally.”

Lexical Resource: Band 5.0

You use several relevant process terms, including “injection well,” “geothermal zone,” “condenser,” “turbines,” and “generator,” which help identify the equipment. However, vocabulary control is limited by frequent spelling errors and imprecise or unnatural expressions. “Winds of turbine” does not describe the process, while “moved in the circular motions” and “stored in the generator” misrepresent how the equipment works. “Electricity supplier” is also not the feature shown in the diagram. Aim for accurate process collocations and consistent spelling; for example, describe water as being “pumped down,” steam as “driving the turbine,” and the generator as “producing electricity.”

Grammatical Range and Accuracy: Band 5.0

You attempt to combine stages using clauses, for example, “which is powered by steam,” and you use some passive forms appropriate to a process description. However, the range of sentence structures is limited, and attempts to build longer sentences often lead to faulty grammar that makes relationships unclear. Examples include “The illustrations shows,” “these steam are,” and “then it will stored”; these involve agreement, number, and verb-form errors. Punctuation and spacing also make sentence boundaries difficult to follow, especially in the long “Initially” sentence. Practise writing shorter, complete sentences with a clear subject and verb, then check agreement and passive forms, such as “The water is pumped down” and “The steam drives the turbine.”
