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 map shows that the process of the geothermal power plant which is produce the electricity from water .

Furthermore, the starts from entering the cold water is pumped in the injection well of 4.5 cm length . Water passes from geothermal zone where hot rocks are placed after that water entered in the production well where hot water in pumped to the condenser . In the condenser puts very high pressure on water . Water starts boiling and formed stream . Addition Stream transferred to the turbine ,turbine starts rotating in clockwise direction and charged after that produced electricity . The electricity is transferred to the towers .

Moreover , in geothermal power plant starts from cold water , pumped to injection well water goes through the geothermal zone that is placed where hot water turned into hot water and pumped to condenser through production well water is streamed and helped to rotate the turbine , The electricity goes to town , shops , rural and urban areas .

Task Achievement / Task Response — Band 6.0

The response covers the main stages of the geothermal energy process, from injection to electricity distribution. However, the description is repetitive, particularly in the second paragraph, which essentially restates the first without adding new information. The summary lacks a clear overview of the process as a whole, which is a requirement for a high band score in Task 1. While the main features are identified, the lack of synthesis and the inclusion of redundant information prevent a higher score. The mention of '4.5 cm length' appears to be a misinterpretation of the diagram, which likely refers to depth or distance, indicating a slight inaccuracy in reporting the data.

Coherence and Cohesion — Band 5.5

The response is divided into paragraphs, but the logical flow is hindered by significant repetition. The second paragraph repeats the sequence described in the first, which creates a disjointed reading experience. While some cohesive devices are used, such as 'Furthermore', 'Moreover', and 'after that', they are often used mechanically or incorrectly. The referencing is sometimes unclear, and the overall progression of the report is circular rather than linear. To improve, you should focus on describing the process once, clearly and sequentially, without restating the same steps.

Lexical Resource — Band 5.5

The vocabulary is somewhat limited and repetitive. Words like 'water', 'pumped', and 'electricity' are used frequently. There are also errors in word choice and collocation, such as 'formed stream' (should be 'steam') and 'charged after that produced electricity'. The use of 'stream' instead of 'steam' is a recurring error that impacts clarity. While the vocabulary is sufficient to convey the basic meaning of the process, it lacks the precision and variety required for a higher band score. You should aim to use more specific technical terminology related to energy production.

Grammatical Range and Accuracy — Band 5.5

The response contains frequent grammatical errors that occasionally impede communication. There are issues with verb forms ('which is produce', 'water is streamed'), sentence structure, and punctuation (e.g., unnecessary spaces before commas). Many sentences are simple, and attempts at more complex structures often result in errors, such as 'the starts from entering the cold water is pumped'. The misuse of articles and prepositions is also common. While the meaning is generally understandable, the high frequency of errors in basic sentence construction limits the score in this criterion.
