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 6.5)

THE PRESENTED DIAGRAM EXPRESSES THE TECHNIQUE OF ENERGY PRODUCTION BY USING VOLCANIC HOT ROCK. PROCESS IS PERFOMED ON LOW COST.

OVERALL, PROCESS GENERATE ELECTRICITY WITH THE HELP OF TURBINE. ENERGY GENERATION COMPLETE IN 5 STAGES. COLD WATER REACHED AT DEEP INSIDE THE EARTH AND CAME OUT IN HOT FORM AND THEN CONVERT INTO STEAM. THEN STEAM PASS THROUGH TURBINE AND GENERATE ELECTRICITY.

FIRSTLY, CHILLY WATER PASS THROUGH GEOTHERMAL ZONE OR VOLCANIC AREA. WHICH CONTAINS HOT ROCKS. HOT ROCKS CONVERT REFERESHING WATER INTO WARM WATER. BOLING WATER TRANSPORT INTO CONDENSOR BY USING HOT WATER PUMP. CONDENSER IS TRANSFORMED HEATED WATER INTO GASEOUS WATER. WATER VAPOR IS DIRECTED TYO TURBINE AND CAUSING IT TO ROTATE.

IN THE FINAL STAGE, SPINNING TURBINE GENERATE ELECTRICITY AND TRANSMITTED FOR THE USE. GEOTHERMAL ENERGY IS TRANSFROMED INTO ELECTRICAL POWER THROUGH SERIOUS OPERATIONS INVOLVING WATER STEAM TURBINE AND GENERATOR. AND ELECTRICITY TRANSFERED TO CITY PEOPLE'S HOME FR THEIR DAILY USEGE.

AI examiner evaluation

Task Achievement / Task Response — Band 6.5

The response covers the main stages of the geothermal energy production process, identifying the key components such as the cold water injection, hot rocks, condenser, and turbine. However, the description is somewhat mechanical and lacks a clear, cohesive overview of the entire system. While the main features are reported, the comparison between stages is limited, and the explanation of the process is occasionally imprecise, such as the description of the condenser's function. The response addresses the prompt adequately but lacks the analytical depth required for a higher band score.

Coherence and Cohesion — Band 6.5

The essay is organized into paragraphs, which helps the reader follow the sequence of events. However, the use of cohesive devices is somewhat mechanical and repetitive (e.g., 'Firstly', 'In the final stage'). There are instances where the logical flow between sentences is disjointed, particularly in the second paragraph where the transition from the overview to the process description feels abrupt. Referencing is generally clear, but the overall progression of ideas could be smoother with more varied linking words and better integration of the process steps.

Lexical Resource — Band 6.0

The vocabulary is adequate for the task but lacks the precision and variety expected at higher levels. There are several instances of awkward word choices or non-standard collocations, such as 'chilly water', 'refreshing water', and 'gaseous water'. Additionally, there are spelling errors throughout the text, such as 'perfomed', 'boling', 'condensor', and 'usege'. While the meaning is generally clear, the limited range of vocabulary and the recurring spelling mistakes prevent the response from reaching a higher band.

Grammatical Range and Accuracy — Band 6.0

The response contains a mix of simple and some attempted complex sentence structures. However, there are frequent grammatical errors, including missing articles ('process is perfomed', 'pass through turbine'), incorrect verb forms ('convert into steam', 'electricity transfered'), and issues with subject-verb agreement. Punctuation is also inconsistent, with some sentences being fragmented or run-on. While these errors do not completely impede communication, they are frequent enough to demonstrate a lack of control over complex grammatical structures.
