IELTS Writing Task 1 question

The diagram below shows how electricity is generated in a hydroelectric power station.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

Student answer (Band 5.0)

The diagram illustarte the how to produced the electricity in a hydroelectric power station .

Overall , there have a several stage , it is linear process , . The process begins with river pressure the dam and terminate with produced the power lines .

Initially , river followed the own route they after water going into the dam . The water intake in only opened in day and this closed in night . The water is flow in to generate the electricity in a day and water flow to up in night time they pumping the water .

Secondly , the water get the more pressure in the power station in they produced the generator after they provide the power lines in different national grid . Subsequently , In day the water going to down and night time they preserve the water . And low level reservour flow the own river .

Task Achievement / Task Response: Band 5.5

You identify the diagram as a hydroelectric process and include several central features: the intake is open by day and closed at night, water moves down to generate electricity, and it is pumped back up at night. However, the account only partly covers the process and some stages are unclear or inaccurate. For example, the overview calls it a “linear process,” although the diagram shows a cycle, and the ending does not clearly explain that water returns from the low-level reservoir through the turbines to the high-level reservoir. The generator, power lines and national grid are mentioned, but their relationship to the water flow is not clearly described. A more accurate overview and a complete, ordered account of both daytime generation and nighttime pumping would strengthen the response.

Coherence and Cohesion: Band 5.0

The response has a basic paragraph structure, moving from an introduction and overview to stages of the process, and sequencing words such as “Initially,” “Secondly” and “Subsequently” show an attempt to guide the reader. However, progression is difficult to follow because the stages are not consistently connected and some references are unclear. For instance, “they after water going into the dam” and “they preserve the water” do not make clear which component or action is meant. The sequence also shifts between daytime and nighttime operations without clearly separating the two cycles. Organise the body into a clear day sequence followed by the night sequence, and use precise references such as “the water,” “the turbines” and “the low-level reservoir” to make the relationships easier to follow.

Lexical Resource: Band 5.0

You use some relevant process vocabulary, including “intake,” “power station,” “generator,” “power lines” and “national grid,” so the reader can recognise the topic. However, the range is limited and several word-choice or word-form errors make meaning difficult to interpret, such as “river pressure the dam,” “produced the power lines” and “preserve the water.” Spelling errors, including “illustarte” and “reservour,” also reduce accuracy. Aim to use precise process verbs and collocations: water “flows” through a conduit, turbines “drive” a generator, and electricity is “transmitted” to the national grid. Reusing accurate technical terms is preferable to choosing a word that does not fit the process.

Grammatical Range and Accuracy: Band 4.5

The response attempts to describe stages using both simple statements and longer clauses, but the range of sentence structures is limited and errors are frequent enough to make several relationships hard to understand. Examples include “there have a several stage,” “The water is flow in to generate” and “the water get the more pressure,” where verb forms, agreement and sentence construction are not controlled. Articles and punctuation are also inconsistent, as in “in a hydroelectric power station .” Practise building clear present-simple sentences for process descriptions, for example, “During the day, water flows through the turbines and drives the generator.” Then connect stages with accurate clauses while checking subject–verb agreement, articles and sentence boundaries.
