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 4.5)

THE DIAGRAM SHOWS HOW GEOMATRICAL ENERGY IS USED TO PRODUCE ELECTRICITY.

FIRSTLY, SHOWS THE COLD WATER IS IN THE TANK AND THE COLD WATER PUMPED DOWN IN THE INJECTION WELL AND THE COLD WATER PIPE LINE IS 4.5 KILOMETER LONG DOWN TO THE EARTH AND THE COLD WATER IS GONE GEOTHERMAL ZONE (HOT ROCK)

THIRDLY, THE PROJECTOR WELL PUMPED WATER TO THE 4.5 KILOMETER LONG PIPE LINE TO THE FORTH STEP CONDENCSER AND THE CONDENSER PRODUCE STEAM AND THE STEAM PUSHED THE FIFTH STEP TURBINE IS ROAMING FATLY AND SEND POWER TO THE GENERATOR WHICH IS POWERD BY TURBINE AND THE GENERATOR PRODUCE ELECTRICITY AND THE ELECTRICITY GONE GENERATOR TO THE TOWER AND THE TOWER SUULY ENERGY TO THE TRANSFORMER AND THE TRANSFORMER SUPPLY ELECTRICITY TO THE FACTORIES AND HOMES AND SHOPPING MALLS THIS STEP IS USED TO PRODUCE ELECTRICITY ALLMOST ALL COUNTRIES USED THIS STEP TO PRODUCE ELECTRICITY BUT ANOTHER SOURSE IS TO BE USED IN MANY COUNTRIES FOR EXAMLE SOLAR ENERGY

I SUMMARISE THE INFORMATION AND GIVE ME GOOD BANDS PLEASE!

Task Achievement / Task Response: Band 4.5

You identify the main process and include several accurate stages: cold water is sent down an injection well, passes through hot rocks, and is brought back up before steam drives a turbine and generator. However, the account is only a partial description of the diagram. The sequence is unclear at points, and “projector well” is not identified accurately as the production well. You also add unsupported details about a transformer, factories, homes, shopping malls, and how widely the process is used; these are not shown. There is no clear overview of the process as a whole. Focus on the diagram’s actual stages and summarise the key transformation from cold water to electricity without adding outside information.

Coherence and Cohesion: Band 4.5

The response attempts to follow the process in sequence, using markers such as “Firstly,” “Thirdly,” and “the fifth step,” so the reader can recognise a basic chronological structure. However, the numbering skips stages, and most of the information is packed into one long paragraph and sentence. This makes relationships between steps difficult to follow, especially in the section beginning “the condenser produce steam.” The final comments about other energy sources also interrupt the process description. Use separate paragraphs for an overview and the stages, then connect each step with clear, accurate transitions such as “Next,” “After this,” and “Finally.”

Lexical Resource: Band 4.5

You use some relevant process vocabulary, including “injection well,” “geothermal zone,” “condenser,” “steam,” “turbine,” and “generator.” This shows a basic ability to name parts of the diagram. However, vocabulary is repetitive and several inaccurate or misspelled choices make the description harder to understand: “geomatrical” for geothermal, “projector well” for production well, “condencser,” “powerd,” and “roaming fatly.” Phrases such as “the electricity gone generator to the tower” are also unclear. Choose precise terms from the diagram and use standard collocations, for example, water is “pumped down,” steam “drives” a turbine, and the generator “produces” electricity. Avoid adding unrelated vocabulary about factories and shopping malls.

Grammatical Range and Accuracy: Band 4.5

The response communicates a few basic process relationships, but sentence structures are very limited and errors are frequent enough to obscure meaning. Several clauses lack a clear subject or verb pattern, as in “Firstly, shows the cold water is in the tank,” while “the condenser produce steam” has incorrect subject–verb agreement. Verb forms are also problematic in “the steam pushed the fifth step turbine” and “the electricity gone generator to the tower.” The long sentence joined by repeated “and” makes it difficult to see where one stage ends and another begins. Practise writing short, complete sentences in the present simple, such as “Cold water is pumped down the injection well” and “Steam drives the turbine.”
