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)

In the given figure demonsrates, the process of producing electricity by using the steam of the water.

overall, in this process we are poducing electricity with the help of steam, in which eject the steam on the turbine blade and the turbine moved at high speed to generate the electicity.

Initially, the process starts from cold water, it below down 4.5 km with the help of pump and then injection wall inject the water into the geothermal zone.At this stage, the temperature of the water is gradually rising.Then, the hot water transfer to the condensor with the help of pump and make steam. The steam pass through the small path and the speed of steam is high, diectly inject on the tubine blade. The enrgy transfer from steam to the turbine blade, it start moving and they ar produce electricity and they tansfer to electricity grids.

This is the complete process of generating the electricity.

Task Achievement / Task Response: Band 5.5

You identify the main purpose of the diagram and give a general overview that steam drives a turbine to generate electricity. You also report the 4.5 km depth and describe the broad sequence from cold water to hot water, steam, and electricity. However, some important stages are unclear or inaccurately described: the water is pumped down the injection well and then rises through a separate production well, but this distinction is blurred. The diagram shows steam powering the turbine, which drives the generator; it does not show steam being injected onto turbine blades at high speed or electricity being transferred to “grids.” To strengthen the summary, describe each stage precisely and include the generator’s role in the process.

Coherence and Cohesion: Band 5.0

The response has a basic structure: an introduction, an overview, a sequence of process details, and a closing sentence. Sequencing words such as “Initially” and “Then” help the reader follow the stages. However, progression is not consistently clear because several steps are compressed into long sentences, and the links between them are sometimes faulty. For example, “Then, the hot water transfer to the condensor with the help of pump and make steam” combines the water’s movement and steam production without clearly showing how one stage leads to the next. The final sentence repeats the idea that the process is complete rather than adding information. Use one clear sentence per stage and connect them with accurate, varied transitions.

Lexical Resource: Band 5.0

You use some relevant process vocabulary, including “geothermal zone,” “injection,” “steam,” “turbine,” and “generate electricity,” which helps communicate the topic. However, the range is limited and several word choices or collocations are inaccurate, sometimes making the process difficult to picture. Phrases such as “eject the steam on the turbine blade,” “small path,” and “transfer to electricity grids” are not natural or precise descriptions of the diagram. There are also noticeable spelling errors, including “poducing,” “electicity,” “condensor,” and “tubine.” Build a more accurate set of process verbs and technical terms, and check spelling carefully so that your meaning is consistently clear.

Grammatical Range and Accuracy: Band 4.5

You attempt both simple and longer sentences, and the response uses sequencing clauses to describe the stages. However, the range is limited, and attempts to combine several actions often produce faulty sentence structures. For instance, “the hot water transfer to the condensor with the help of pump and make steam” lacks correct verb forms and does not clearly identify who or what makes the steam. There are also recurring problems with agreement and tense, as in “the turbine moved” and “they ar produce electricity,” as well as missing or incorrect articles and punctuation. These errors can make parts of the process hard to follow. Practise accurate present-simple passive forms, such as “water is pumped down” and “steam is produced,” and separate complex stages into controlled sentences.
