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 diagram represents that how geothermal energy is used to make electricity.

Overall, we see the steps from start to end and check that how the cold water is used for producing electricity. There are alot of steps and we follow this process step by step.

First of al, the cold water is pumped dowward under the earth about 4.5 km deeply and then in second step, the injection well pushed the liquid towards the geothermal zone(hot rocks). The water is pumped upward by the production well and it becomes hot water due to heat of the rocks.

The water is goes to the condnser and become steam in forth step. The steam are go into turbine and rotate it in one direction. The turbine powered the generator to produce electicity. In the last, the electricity produced by generator are go to the geothermal power plant and then is distributes it.

Task Achievement / Task Response: Band 5.5

You identify the main sequence, from cold water being sent underground to electricity being generated, and include the important depth of 4.5 km. The description of water passing through hot rocks and returning via the production well is also relevant. However, the overview is vague: “we see the steps from start to end” does not clearly summarise how the process works. Some details are inaccurate or unclear. The diagram shows the water becoming steam in the condenser, but “The water is goes to the condnser and become steam” does not explain this clearly. The final electricity is sent through power lines for transmission, not “to the geothermal power plant.” A more precise overview and accurate account of the final stages would make the response more complete.

Coherence and Cohesion: Band 6.0

The response follows the process in a generally logical order, and the use of “First,” “then,” and “In the last” helps the reader track the stages. The paragraphing also separates the introduction and overview from the process description. However, some linking is mechanical or unclear, particularly “in second step” and “in forth step,” and the overview repeats the idea of following the steps rather than summarising the process. The final sentence is difficult to follow because it combines electricity generation and distribution without a clear connection. Use a small number of precise sequence markers and organise the stages into clear groups, such as underground heating and surface electricity generation.

Lexical Resource: Band 5.0

You use several relevant process terms, including “injection well,” “production well,” “geothermal zone,” “turbine,” and “generator,” which help communicate the subject. However, the range is limited and some word choices or forms are inaccurate, making parts of the description awkward: “the injection well pushed the liquid” and “the steam are go into turbine.” There are also noticeable spelling errors, such as “alot,” “condnser,” and “electicity.” Choose precise process verbs and check spelling carefully. For example, describe water as being pumped through the hot-rock zone, then converted into steam, which drives the turbine. Avoid vague phrases such as “in one direction” when they do not add useful information.

Grammatical Range and Accuracy: Band 5.0

The response attempts both simple and longer sentences, and the sequence is mostly understandable. However, errors occur frequently in verb forms, agreement, and sentence construction, sometimes making the process difficult to interpret. Examples include “The water is goes,” “The steam are go,” and “the electricity produced by generator are go.” The opening phrase “represents that how” also uses an incorrect clause pattern. Practise using passive forms for process descriptions, such as “Cold water is pumped down” and “The water is heated as it passes through the rocks.” Check subject–verb agreement and keep each stage in a complete, clearly structured sentence.
