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 given flow chart illustrates the steps to produce electricity by geothermal energy. overall, this process include five steps such as cold water, the injection well , the production well , condenser , and last step turbine .

To commence with , the proccedure starts from first step containing cold water which will be pumped down through pipe of 4.5 km , secondly the water transfer to the injection well will convert into hot water in geothermal zone by hot rocks present there , in third step the hot water will move towards the production well to get pump upwards.

Then the water which move upward from production well will enter in condenser which is the fourth step , helps to convert warm water into steam as steam plays major role in generating the electricity , last but not the least , steam enters with high pressure which in torn rotates the turbine resulting in the production of electricity in the generator. which is then suplied to towers for usage.

Task Achievement / Task Response — Band 5.5

The response provides a clear overview of the geothermal energy production process. You have identified the main stages, such as the injection of water, heating by rocks, and the generation of electricity. However, the description of the process is slightly inaccurate in places; for example, the condenser is described as converting warm water into steam, whereas the diagram indicates the steam is produced by the heat of the rocks and the condenser is used to cool the steam back into water. To reach a higher band, ensure that the technical details are interpreted precisely from the visual data provided.

Coherence and Cohesion — Band 5.5

The essay is organized into three paragraphs, which helps the reader follow the sequence of events. You use some cohesive devices like 'To commence with', 'secondly', and 'Then' to link ideas. However, the flow is occasionally interrupted by awkward phrasing and punctuation errors, such as the sentence fragment starting with 'which is then supplied'. The use of cohesive devices is sometimes mechanical, and the paragraphing could be more balanced to separate the introduction from the body of the process description.

Lexical Resource — Band 5.5

You have used a sufficient range of vocabulary to describe the process, including terms like 'geothermal zone', 'injection well', and 'turbine'. However, there are several spelling errors ('proccedure', 'suplied') and minor word choice inaccuracies ('in torn' instead of 'in turn'). While the vocabulary is adequate for the task, it lacks the precision and sophistication required for higher bands. Focusing on accurate spelling and more natural collocations will improve your score in this area.

Grammatical Range and Accuracy — Band 5.5

The response contains a mix of simple and complex sentence structures. There are frequent grammatical errors, particularly with verb tenses and sentence boundaries. For instance, 'the water transfer to the injection well will convert' should be 'the water transferred to the injection well is converted'. Additionally, there are issues with article usage and punctuation, such as the unnecessary capitalization of 'Overall' and the misuse of periods. While these errors do not completely impede communication, they are frequent enough to limit the score.
