IELTS Writing Task 1 question
The diagram below shows how a biofuel called ethanol is produced.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
Student answer (Band 5.5)
Given illustrations explains the whole cycle of ethnol production. Which is bassically a biofuel.
From growing plants till the fuel making, and again how emitted gases from the vehicles will helps plants to regrow. Diagram explains the whole concept.
First of all, we have to grow plants, after this harvesting proccess will starts, farmer take that cutted leaves to the crushing machine, it converts them in to a cellolose. Chemical proccess will happen after this stage, and converts cellulose in to sugar molecules afterwards, with the help of microbes ethanol production starts.
Ethanol is biofuel means, it doesnot harm the enviorment, when we use this fuel in to cars, trucks and planes etc. Then this fuel become CO2 after burning. This gas is helps plants to regrow because, we all know leaves extract co2 and ommitt oxygen. In this way the cycle of ethanol production starts with nature and end with nature.

Task Achievement / Task Response: Band 6.0
You identify the diagram as a cycle and cover its main stages, from plant growth and harvesting through processing, sugar production, microbes and ethanol, then fuel use and carbon dioxide returning to plants. This gives the reader a relevant overall account. However, some details are inaccurate or unclear: the diagram shows pre-processing producing cellulose, but it does not specify crushing leaves; nor does it say ethanol is harmless or that the fuel itself becomes CO₂. The overview could also state more precisely that sunlight and carbon dioxide support plant growth and that CO₂ released by transport completes the cycle. These points make some parts of the process less fully and accurately reported than others. Focus on describing only what the diagram shows and avoid adding scientific claims.
Coherence and Cohesion: Band 5.5
The response follows the process in a broadly logical order, and the paragraph break separates the production stages from the fuel-use cycle. Linking phrases such as “after this” and “afterwards” help show sequence. However, the opening is fragmented (“Given illustrations explains…” and “Which is…”), and the final sentence repeats the idea that the cycle begins and ends with nature rather than adding a distinct summary. Some connections are also unclear, particularly “Then this fuel become CO2 after burning,” which makes the relationship between fuel use and emissions difficult to follow. Use a clear introduction and overview, then group the stages into a production paragraph and a transport/emissions paragraph, with precise transitions between them.
Lexical Resource: Band 5.0
You use some relevant process vocabulary, including “harvesting,” “cellulose,” “microbes,” “ethanol,” and “CO2,” so the topic is generally identifiable. However, the range is limited and several word choices or spelling errors reduce precision, such as “ethnol,” “cutted leaves,” “crushing machine,” and “sugar molecules.” The diagram’s labels offer more accurate terms, including “pre-processing,” “processing,” and “sugars”; using these would make the account more faithful and appropriately formal. Informal or imprecise expressions such as “we all know” and “etc.” are also unsuitable for a concise academic process description. Aim for accurate process terminology and check spelling before submitting.
Grammatical Range and Accuracy: Band 5.0
There are attempts to connect stages in longer sentences, for example, “Chemical proccess will happen after this stage, and converts cellulose in to sugar molecules afterwards.” However, control of sentence structure and verb forms is inconsistent, and several errors make the description less clear. Examples include the opening “Given illustrations explains,” the fragment “Which is bassically a biofuel,” “harvesting proccess will starts,” and “This gas is helps plants to regrow.” Articles, agreement, and tense also need attention. Practise forming complete sentences with a clear subject and verb, and use the present simple consistently for a process: for example, “The material is processed into sugars, and microbes are then added.” More accurate sentence patterns would improve clarity.
