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 5.0)

The diagram describes the information of producing the biofuel called ethanol.

Overall, there are serval stages of producing ethanol fuel, the process is began from harvesting trees and plants after that is goes next for pre-processing, morever after circulating in different stages the ethanol is produce.

The intial step is harvesting plants and tress and the next stage is pre processing in which plants are goes into the mixture, while than the next process is cellulose after that is sents to processing.

After processing sugars is the next task of the procdure, in the very next step is the adding microbes in sugers, and finally the ethanol produce. And the biofuel ethanol is use for carbon dioxide in cars, Trucks and also for the plane.

Task Achievement / Task Response: Band 5.0

You identify the topic and give a basic sequence, including pre-processing, cellulose, processing, sugars, microbes and ethanol. However, the account only partially covers the diagram: it omits the initial growth stage powered by sunlight and carbon dioxide, and does not explain that carbon dioxide from vehicles returns to support plant growth. The overview is also unclear and inaccurate: “the process is began from harvesting” misses the true starting point, while “ethanol is use for carbon dioxide” misrepresents the relationship between ethanol, transport and emissions. Some details, such as plants going “into the mixture,” are not shown in the visual. The response is 25 words below the required minimum, which limits the opportunity to report the main features fully. Include the complete cycle and a clear overview.

Coherence and Cohesion: Band 5.5

The response has separate paragraphs and generally follows the production stages in sequence, so the reader can recognise a basic progression from harvesting to ethanol. You also use linking expressions such as “the next stage,” “after that” and “finally.” However, progression is weakened by repeated, sometimes inaccurate transitions, and the overview does not clearly organise the whole cycle. The final sentence introduces transport and carbon dioxide without explaining how these connect back to plant growth. Some links are difficult to follow, as in “after circulating in different stages the ethanol is produce.” Group the stages into a clear beginning, processing sequence and end-use/recycling stage, and use precise connectors to show the relationships.

Lexical Resource: Band 5.0

You use some relevant process vocabulary, including “harvesting,” “pre-processing,” “cellulose,” “sugars” and “microbes,” which helps communicate the subject. However, the range is limited and several word choices or collocations are inaccurate, sometimes making the process unclear. For example, “describes the information of producing” is unnatural, “the next task” is not a suitable label for a process stage, and “ethanol is use for carbon dioxide” confuses the fuel with the emissions. Spelling errors such as “serval,” “intial,” “tress” and “procdure” are noticeable. Aim for accurate process language such as “is converted into,” “is then processed” and “is used as fuel,” and check spelling before submitting.

Grammatical Range and Accuracy: Band 4.5

You attempt to connect stages in longer sentences, but the range of sentence structures is limited and these attempts often contain errors that make relationships difficult to understand. Examples include “the process is began,” “plants are goes into the mixture,” and “the ethanol produce,” where verb forms and agreement are not controlled. The sentence beginning “Overall” also has faulty construction: “the process is began from harvesting trees and plants after that is goes next.” Articles and plurals are inconsistent, as in “adding microbes in sugers” and “for the plane.” Use a reliable passive pattern for this process—“Plants are harvested,” “the material is processed,” and “ethanol is produced”—and separate stages into shorter, correctly punctuated sentences.
