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 Diagram provides information about how with the help of water we produce electricity. It illustrates the working system of the Geothermal power plant.

In this Diagram we see how electricity produce in the geothermal plant. First cold water goes into the pipes and become hot and with the steam of hot water it makes electricity.

Intially the cold water comes down in the hot rocks. By crossing these rocks the water becomes hot and than the steam of water it goes to the condenser. Condenser is a container that stores steam.

Secondly the process of making electicity with the help of turbine. The Turbine swings and it goes to the generator which is powered by turbine and the generator hold the electricity and it gives to the electricity towers and than the electricity into our homes. tis is the process of geothermal plant.

Task Achievement / Task Response: Band 4.5

You identify the subject as a geothermal power plant and mention several relevant stages, including cold water, hot rocks, a condenser, a turbine and a generator. However, the account is incomplete and contains important inaccuracies: the water is heated underground, then pumped up the production well; it is not described as becoming steam before reaching the condenser. The condenser is said to store steam, whereas the diagram shows it releasing steam. The overview is also unclear, and the final claim that electricity is sent to homes is not shown. The response is six words below the required minimum. To improve, give a concise overview and accurately describe the full sequence, including the 4.5 km injection well and the generator’s role.

Coherence and Cohesion: Band 5.5

The response has a basic sequence, moving from cold water underground to the turbine and generator, and paragraph breaks help separate parts of the explanation. However, progression is not consistently clear: the second paragraph gives a compressed summary, while the next paragraph returns to the early stages. “First” and “Secondly” do not reliably guide the reader through the process, and the transition from the condenser to steam and the turbine is difficult to follow. Some references, such as “it” in “it goes to the generator,” are unclear. Organise the stages in one continuous order and use precise links such as “After being heated” and “The resulting steam then drives the turbine.”

Lexical Resource: Band 5.0

You use some relevant process vocabulary, including “geothermal power plant,” “condenser,” “turbine” and “generator,” so the topic is generally recognisable. However, the range is limited and several choices are imprecise or repetitive: “makes electricity” and “hold the electricity” do not describe the equipment’s functions accurately, while “swings” is not an appropriate description of a turbine. There are also noticeable spelling errors, including “Intially,” “electicity” and “than” where “then” is intended. Use accurate process verbs and check spelling carefully; for example, say that steam “drives” the turbine and the generator “produces” electricity.

Grammatical Range and Accuracy: Band 5.0

You attempt both simple and joined sentences, and the overall meaning can usually be understood. However, errors are frequent, and attempts at longer structures are often faulty. For example, “how electricity produce” is missing the passive verb form, and “cold water goes into the pipes and become hot” has a subject–verb agreement error. In “By crossing these rocks the water becomes hot and than the steam of water it goes to the condenser,” the clause structure and reference are unclear. Articles, verb forms and sentence boundaries also need attention. Practise accurate passive constructions such as “Cold water is pumped down” and “The water is heated,” then build longer sentences around these forms.
