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 illustrate the process of making ethanol.

It is evident that there are thirteen stages of proudcing ethanol,Beginning with planting and growing trees and ending with the many differents sacteors where ethanol are used.

At the begnning of the process, energy wa collected from plants and trees,after that this trees are harvest by harvesting machine.Next process is the harvesting plants put on ore processing and here the plants is being cellulose and than the cellulose transfer in a lab where its start to processing ,and it come out as a form by sugar .

In the remaining stages, in sugar mrcrobes are do add and finally it come out by ethanol ,after that it transfered in many companies and here they use it in many transport ,such as carbon dioxide

Task Achievement / Task Response: Band 4.5

You identify the general subject and describe several central stages, including harvesting, processing cellulose into sugars, adding microbes, and producing ethanol. However, the account is incomplete and contains important inaccuracies: the diagram begins with sunlight and carbon dioxide supporting plant growth, not energy being collected from plants, and it ends with carbon dioxide returning to the plants rather than ethanol being transferred to companies. The overview also gives “thirteen stages,” which is not a clear or accurate summary of the process. The transport uses are mentioned, but the carbon cycle is not explained. The response is also below the required 150 words, leaving little room to report the full sequence and its main features. Describe the cycle accurately and include a concise overview.

Coherence and Cohesion: Band 5.5

There is a basic attempt to organise the response into an introduction, an overview, and two stages of description. Phrases such as “At the beginning” and “In the remaining stages” help signal sequence, so the reader can follow parts of the process. However, progression becomes difficult to track in the long middle sentence, which combines harvesting, pre-processing, cellulose, and processing without clear boundaries. Some links are also inaccurate or unclear, such as “after that this trees” and “after that it transferred.” Use one sentence for each group of stages, and connect them with precise sequence markers such as “Next,” “Following this,” and “Finally.” Clearer paragraphing and references would make the process easier to follow.

Lexical Resource: Band 5.0

You use some relevant process vocabulary, including “harvesting,” “processing,” “cellulose,” “microbes,” and “ethanol,” which helps convey the topic. However, the range is limited, and several word choices or spelling errors make the description difficult to understand: “proudcing,” “begnning,” “sacteors,” and “mrcrobes” appear in key parts of the response. Some phrases are also unsuitable for describing the diagram, such as “many companies” and “they use it in many transport.” Aim for accurate process terms and natural collocations, for example, “is converted into sugars” and “is used as fuel in vehicles.” Proofreading spelling and choosing precise verbs would improve clarity.

Grammatical Range and Accuracy: Band 5.0

The response attempts both simple statements and longer sentences, and the sequence is sometimes expressed with clauses such as “after that.” However, the longer structures are often faulty, and errors in verb forms, agreement, articles, and sentence boundaries frequently make the meaning hard to follow. For example, “The diagram illustrate” needs subject–verb agreement, while “the plants is being cellulose” does not form a correct passive construction. “Ethanol are used” also has incorrect agreement, and several sentences run together without appropriate punctuation. Practise accurate passive forms for process descriptions: “the plants are harvested,” “the material is processed,” and “ethanol is produced.” Shorter, correctly punctuated sentences would help establish control before adding complexity.
