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 image represents the process involved in production of biofuel called ethanol.

overall, manufacturing of eathanol is a circular ongoing process which involves , for instance procurment of raw material from nature , processing the harvested material in factories by adding certain microbes which leads to ethanl formation and fuel cumbustion leads co2 production which aids the plants for photosynthesis.

firstly, plants and trees are harvested from cultivated lands then the remaining raw material witness pre - processing which breaks up the wood molecule into cellulose . moreover, the cellulose are then goes for further processing which converts in sugar molecules . certain microbes are mixed with sugars that resultant in formation of ethanol.

secondly, after etnanol production this cycles repeats it self naturally by cumbustion process. in detail, when fuel gets burned by vechils which results in formation of biproduct co2 and this co2 is helpful for plats .

Task Achievement / Task Response: Band 6.5

You identify the diagram as a circular production process and include its main stages: harvesting, pre-processing, cellulose, processing, sugars, microbes and ethanol. Your overview also captures the important link between carbon dioxide from fuel use and plant growth, so the response addresses the task well. Some details, however, are less fully or accurately reported. The diagram shows sunlight and carbon dioxide supporting plant growth before harvesting, but this opening stage is omitted. It also shows ethanol being used by a car, truck and aeroplane; describing only fuel burned by “vechils” is less specific. The claim that pre-processing “breaks up the wood molecule” is not stated in the diagram. Include the full cycle and avoid adding unsupported process details to strengthen the report.

Coherence and Cohesion: Band 6.0

The response has a recognisable structure: an introduction and overview are followed by two paragraphs describing production and fuel use. The sequence within the first body paragraph is generally easy to follow, and “firstly” and “secondly” signal the two broad parts of the cycle. However, these connectors are somewhat mechanical, and “secondly” suggests a separate stage rather than the continuation of a circular process. The overview sentence is also crowded with several stages, making the relationships harder to follow. Some links between ideas are unclear, particularly “this cycles repeats it self naturally by cumbustion process.” Use clearer stage-to-stage transitions such as “Once ethanol is produced” and “When it is burned,” and give each paragraph a focused purpose.

Lexical Resource: Band 5.5

You use relevant process vocabulary, including “pre-processing,” “cellulose,” “microbes,” “formation” and “photosynthesis,” which helps convey the subject. There is also some attempt to use more formal wording, such as “manufacturing” and “biproduct.” However, spelling and word-choice problems are noticeable and sometimes make the description less precise: “eathanol,” “etnanol,” “cumbustion,” “vechils” and “plats” recur or obscure meaning. Some combinations are unnatural, including “raw material witness pre-processing” and “microbes are mixed with sugars that resultant in formation.” Choose standard process collocations and check spelling carefully. More precise terms for the diagram’s stages and transport uses would make the vocabulary more controlled and appropriate to an academic process description.

Grammatical Range and Accuracy: Band 5.0

You attempt both simple and complex sentences, including a relative clause in “fuel gets burned by vechils which results in formation…” and a longer overview linking several stages. This shows some range, but control is inconsistent, and errors sometimes make relationships difficult to understand. For example, “the cellulose are then goes” combines incompatible verb forms and has an agreement error; “which resultant in formation” is also not a grammatical clause. Other problems include “this cycles repeats it self” and missing articles in phrases such as “in formation of ethanol.” Sentence boundaries and punctuation are also uneven. Build accuracy first with clear subject–verb patterns, then add subordinate clauses only when their structure is secure.
