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 given diagram presents the process of a biofuel, named ethanol is made.

Overall, the ethanol process is consist of eight different steps, starting from the photosynthesis action of the plants and tress, and ending with the emission of carbon dioxide from multiple kind of transports such as car, truck and plains.

In detail, the plants and trees use sunlight and carbon dioxide as an energy source, and by their photosynthesis action they grow in number and size. Next to it, thses tress and plants are harvested by machinary like tractors and cutters and transported to factories. After this, through pre-processing these items converted into cellulose, a intial stage of suger. In 4th step, this cellulose underwents different chemical procedures and adapted the form of suger. Finally, with the addition of some microbes into suger, the ethanol is made and this is used in all kind of transportation. During the burning of this biofuel ,the carbon dioxide is discharged into air by cars, buses and airjets, and this gass is again used by plants and trees for their growth. In this way this process continue works.

Task Achievement / Task Response: Band 6.0

You identify the process as cyclical and give a clear start-to-finish account, including plant growth, harvesting, conversion to ethanol, its use in transport, and carbon dioxide returning to plants. This covers the main stages, but some details are inaccurate or unclear: the diagram shows cellulose being processed into sugars, whereas “a initial stage of suger” suggests the reverse relationship, and it does not show transport to factories or buses and cutters. The overview also calls the process eight steps, although the diagram presents more stages, and “photosynthesis” is an interpretation rather than a labelled stage. To strengthen the report, describe the cellulose-to-sugars conversion precisely and distinguish the production stages from the later fuel-use and carbon cycle.

Coherence and Cohesion: Band 6.0

The response has a recognisable structure: an introduction, an overview, and a detailed sequence. Sequencing expressions such as “Next,” “After this,” and “Finally” help the reader follow the process, and the final sentence returns to the cycle’s starting point. However, the progression is sometimes mechanical, and the phrase “In 4th step” interrupts the otherwise chronological account. Some links between stages are unclear—for example, the sentence about pre-processing and cellulose does not clearly show what happens before the separate processing stage. Organise the body around the production sequence, then the fuel’s use and carbon return, and use precise references to connect each stage.

Lexical Resource: Band 5.5

You use relevant process vocabulary, including “pre-processing,” “cellulose,” “microbes,” “ethanol,” and “carbon dioxide,” which allows you to cover the diagram’s subject. There is also some attempt at more formal phrasing, such as “emission” and “chemical procedures.” However, several word choices and collocations are inaccurate or awkward: “the process of a biofuel,” “grow in number and size,” and “adapted the form of suger” do not express the stages naturally. Spelling errors such as “thses,” “machinary,” “suger,” and “gass” also reduce precision. Build a more accurate process vocabulary and check spelling; prefer direct terms such as “are converted into” when describing material changes.

Grammatical Range and Accuracy: Band 5.5

You attempt both simple and complex sentences, including clauses linked with “and,” “after,” and “during,” and the overall meaning is generally understandable. Some grammatical errors remain, particularly with verb forms, agreement, and articles. For example, “the process … is consist of” should be “consists of,” while “these items converted” needs a passive verb form (“are converted”). “This process continue works” also has an incorrect verb construction, and “a initial stage” has an article error. Sentence boundaries and punctuation are mostly manageable, though spacing around commas is inconsistent. Practise accurate passive forms for process descriptions and check each sentence for a complete, correctly formed verb.
