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)

In this Chart We can Clearly see the process in which geothermal energy used to generate Electricity.

Under this picture we have different components and parts to performe this cycle

firstly, we have cold water and push his pressure 4.5Km down with very narrow path to the injection walls, while passing through geothrtmal zone that can increase the temprature of water with hot shild of rocks.

In The Upword senerio, Third Important part is to pull back that hort water toward the codenser, In this point water produce it's max steam to the tubes at the edge of that tube have set of turbines that convert it into the form of Electricity.

In the End wave of current Pass to the Big Atnetas and pass it to the comercial world

Task Achievement / Task Response: Band 5.0

You identify the general purpose of the diagram and describe several stages, including water being sent underground, heated by hot rocks, and returned to the surface. However, the account is only partial: it does not clearly explain the full sequence from the production well to steam, turbine, generator, and electricity transmission, and it gives no concise overview of the process as a whole. Some details are inaccurate or unclear, such as saying the water is pushed down “with very narrow path” and that it produces “max steam” at the condenser. The response also falls 20 words short of the required minimum, limiting the detail you can provide. To strengthen the report, cover each main stage accurately and include a clear overview.

Coherence and Cohesion: Band 6.0

The stages are presented in a broadly sensible order, moving from cold water underground to the return of hot water and then electricity. Sequencing phrases such as “firstly,” “In The Upword senerio,” and “In the End” help signal progression. However, the response is written as one continuous block, so the stages are not clearly grouped, and some links between them are difficult to follow. For example, the transition from the condenser to the turbines is compressed into a confusing sentence, while the final reference to current and antennas is not clearly connected to the generator. Use separate paragraphs for the overview and process details, and connect each stage explicitly with accurate references such as “the heated water then rises” and “the resulting steam drives the turbine.”

Lexical Resource: Band 5.0

You attempt some relevant process vocabulary, including “geothermal zone,” “injection,” “condenser,” “turbines,” and “Electricity.” These terms show awareness of the subject, but the range is limited and several word choices or spellings make the description difficult to understand. Examples include “hort water,” “codenser,” “hot shild of rocks,” and “Big Atnetas”; the last phrase does not accurately describe the transmission pylon. Some expressions are also imprecise, such as “pull back” for water rising through the production well and “max steam” for steam being produced. Aim for standard technical terms and check spelling, collocation, and word forms before submitting.

Grammatical Range and Accuracy: Band 5.0

The response attempts to combine stages in longer sentences, for example, “while passing through geothrtmal zone…” and “In this point water produce…,” but these structures are often faulty. There are frequent problems with sentence boundaries, verb forms, articles, and agreement: “geothermal energy used” needs a passive verb, “water produce” needs subject–verb agreement, and “that convert it” does not agree with “turbines.” Capitalisation and punctuation are also inconsistent, with unnecessary capitals in “Chart,” “Clearly,” and “Electricity,” and several sentences lacking clear punctuation. These errors sometimes make the process hard to follow. Build accuracy first with clear simple sentences, then add subordinate clauses once the basic verb forms and sentence boundaries are secure.
