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 process charts given information about geothermal energy by used to produce electricity.

Ovrall, it can be clearly seen that it has 5 step process started with splya to cold water and ending with current passed to generator.it has somecmplicated process.

Bening with, storenged to cold water afther that cold water down to earth by pumped.and that type of zone is geothermal zne and afthe that time water is hot nd this water is eart o condner this is 4 th step at tht time water covted by steam and it is steam passed tunale in turbin and turbine is used steam so turine is roteted faially producee current storeg in generator amd this type of genertor get cueernt in vairy type compain ns city.

Task Achievement / Task Response — Band 5.5

The response fails to meet the minimum word count requirement of 150 words, which significantly impacts the task achievement score. While the student attempts to describe the geothermal energy process, the explanation is fragmented and lacks the necessary detail to fully cover the stages shown in the diagram. Key features, such as the specific role of the condenser or the cooling tower, are either omitted or described in a way that is difficult to follow. The summary is underdeveloped, and the lack of length prevents a comprehensive overview of the process. To improve, the student must ensure all stages are clearly identified and described in sufficient detail to meet the word count requirement.

Coherence and Cohesion — Band 5.5

The organization of the response is weak. While there is an attempt at paragraphing, the logical flow is disrupted by frequent grammatical errors and poor sentence structure. Cohesive devices are largely absent or misused, making it difficult for the reader to follow the progression of the geothermal process. The transition between steps is often unclear, and the lack of cohesive links between sentences results in a disjointed text. To improve, the student should focus on using clear linking words (e.g., 'subsequently,' 'following this,' 'as a result') to connect ideas and ensure that each paragraph has a clear, logical focus.

Lexical Resource — Band 5.5

The vocabulary is very limited and often inaccurate, which frequently impedes communication. There are numerous spelling errors throughout the text, such as 'Ovrall,' 'splya,' 'storenged,' and 'tunale.' The student struggles to use technical terminology correctly, often resorting to vague or incorrect phrasing like 'vairy type compain ns city' instead of describing the distribution of electricity. The range of vocabulary is insufficient to describe a technical process accurately. To improve, the student should focus on learning and correctly spelling technical terms related to energy production and practice using more precise verbs and nouns to describe mechanical processes.

Grammatical Range and Accuracy — Band 5.5

The grammatical control is poor, with frequent errors in sentence construction, verb tense, and word order that make the text difficult to understand. Many sentences are incomplete or lack proper punctuation, such as 'Bening with, storenged to cold water afther that cold water down to earth by pumped.' There is a lack of complex sentence structures, and the basic structures used are often faulty. The frequent errors in subject-verb agreement and word formation significantly hinder the clarity of the writing. To improve, the student needs to focus on basic sentence construction, ensuring every sentence has a clear subject and verb, and work on consistent verb tense usage.
