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)

This is ethanol cycle. it is illustrate information about production of biofuel and their different stapes of transfer and back to basic one like frist satpe.

Overall, energy use by trees as a sun light and carbon dioxide.it is most important part of cycle.Second one is ethanol burn as a fuel and return back in environment.

Grew plant or crop harvesting by farmers and go for pre-processing.After that cellulose convert into sugars through main chemical processing. Now microbes addition in sugers and ethanol retrival from them. That stape know as a farmentation.Ethanol use in vehicals and jet plans as a fuel.That fuel burn and make carbon dioxide which use again by trees and plants.

Task Achievement / Task Response: Band 5.0

You identify the main stages, from plant growth and harvesting through processing, the addition of microbes, and ethanol use in transport. You also recognise the cycle’s key feature: carbon dioxide released when the fuel is used returns to support plant growth. However, the account is partial and underdeveloped: it does not clearly explain that sunlight and carbon dioxide enable plant growth, and it omits the three transport modes and the repeated carbon-dioxide links. The overview is present but vague (“energy use by trees” and “return back in environment”), and the claim that ethanol is “burn” does not clearly describe its use as fuel. The response is also 36 words below the required minimum. Add a fuller overview and explain the stages and cycle more precisely.

Coherence and Cohesion: Band 5.5

The response follows a broadly sensible order, moving from plant growth to harvesting, processing, ethanol production, and fuel use. The opening overview also signals that the process is cyclical. However, the organisation is not consistently clear: the first paragraph is difficult to interpret, and the second paragraph’s “Overall” statement does not clearly summarise the whole process. Connections between stages are often abrupt, as in “After that cellulose convert into sugars,” while “That stape” does not clearly refer to a specific stage. Paragraphing is present, but the progression would be easier to follow if you used a clear introduction, a concise overview, and a step-by-step description with accurate linking phrases such as “Next,” “Following this,” and “Finally.”

Lexical Resource: Band 5.0

You attempt relevant process vocabulary, including “pre-processing,” “cellulose,” “microbes,” and “carbon dioxide,” and these terms help convey the general subject. However, the range is limited, and several inaccurate word choices or spellings make the description harder to understand: “stapes,” “frist satpe,” “sugers,” “retrival,” and “farmentation.” Some phrases are also unnatural or imprecise, such as “energy use by trees” and “return back in environment.” Use the diagram’s labels accurately and choose standard process terms, for example, “fermentation” and “ethanol is used as fuel.” More precise verbs such as “is converted,” “is harvested,” and “is released” would also make the account clearer and more suitable for an academic process description.

Grammatical Range and Accuracy: Band 4.5

You communicate the general sequence using mostly short statements, and you attempt to connect stages with phrases such as “After that” and “which use again by trees and plants.” However, the range of sentence structures is limited, and frequent errors in sentence formation, verb forms, articles, and agreement sometimes make meaning difficult to follow. For example, “This is ethanol cycle” needs an article, while “it is illustrate information” has an incorrect verb construction. In “cellulose convert into sugars,” the verb form and passive structure are missing; “microbes addition” is not a complete grammatical clause. Practise writing complete sentences with accurate passive forms, such as “Cellulose is converted into sugars,” and check punctuation and capitalisation between sentences.
