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 6.0)

The diagram illustrates the production process of a biofuel called ethanol.

Overall, the procedure consists of several distinct phases. It starts from the cultivation of plants and trees and after passing it throught different steps ultimately making it accessiable for transportation.

Initially, the process starts when plants and trees take sun light and carbon dioxide for germination. When the plants and trees grow up they are harvested by using agriculture machinery. The pre-processing task is completed in third stage. In forth step the process of making cellulose is accomplished. The cellulose are shifted to next step were chemicals are mixed in these cellulose for producing sugars.

Moreover, the sugars are sent to next step where microbes are added into the sugar for making ethanol. Ethanol is used in different transportation moods including cars, trucks and aeroplanes. Therse transport sources exhale carbon dioxide in atmosphere and the process starts again and again.

Task Achievement / Task Response: Band 6.0

You identify the diagram as an ethanol-production process and include its main stages, from plant growth and harvesting through processing, sugar production, microbial action and transport use. You also note the return of carbon dioxide, capturing the cycle’s key feature. However, some details are inaccurate or unclear: the diagram shows sunlight and carbon dioxide supporting plant growth, not plants taking them “for germination”; it does not specify that chemicals are mixed in during processing; and cellulose is produced after pre-processing rather than being “made” in a separate numbered step. The overview is also general and does not clearly summarise the conversion from plant material to fuel and the carbon cycle. More precise reporting of these stages would make the account more complete.

Coherence and Cohesion: Band 6.5

The response has a clear overall shape: an introduction and overview are followed by the early production stages and then the later stages and transport. Sequencing expressions such as “Initially,” “In forth step” and “Moreover” help the reader follow the process, and the final sentence returns to the cycle. This meets the lower-level expectation of coherent organisation and shows some progression beyond it. To make the flow more consistently smooth, avoid relying on numbered transitions when the diagram does not number the stages, and connect related steps more explicitly—for example, explain how pre-processing yields cellulose and how processing converts it into sugars. The phrase “the process starts again and again” is also a vague ending rather than a precise link back to plant growth.

Lexical Resource: Band 5.5

You use relevant process vocabulary, including “harvested,” “pre-processing,” “cellulose,” “microbes” and “carbon dioxide,” so the reader can identify the main subject and stages. There is also some attempt at more formal wording, such as “distinct phases.” However, several noticeable spelling and word-choice problems reduce precision: “accessiable,” “Thर्सe,” “sun light,” and “transportation moods” are inaccurate, while “exhale carbon dioxide” is not the natural verb for emissions from vehicles. “Agriculture machinery” is also an awkward collocation. Aim for accurate process terms and check spelling; prefer “available for use as fuel,” “modes of transport,” and “release carbon dioxide.” This would make the vocabulary more dependable and appropriate to an academic process description.

Grammatical Range and Accuracy: Band 5.5

You attempt both simple and more complex sentences, including a relative clause in “where microbes are added” and a time clause beginning “When the plants and trees grow up.” The sequence is generally understandable, but some grammatical errors remain. For example, “it starts from the cultivation … and after passing it … ultimately making” has an incomplete, awkwardly joined structure; “The cellulose are shifted” has subject–verb disagreement; and “in third stage” and “In forth step” omit the article. The sentence about chemicals also has an unclear grammatical relationship between the material and the action. Use complete clauses with consistent subjects, check singular/plural agreement, and include articles where needed. These revisions would improve accuracy while preserving your attempts at varied sentence forms.
