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 figure illustrates the ethanol cycle and how it produced in the laps and it use .

overall, the ethanol mainly produced in the laps from the sugar that extract from t the trees, and used as fuel in the most of the transportation vehicles that produce carbon dioxide which the tee consume it.

The process begin in the tress that use carbon dioxide and sunligh to make their nutrition and grow. Second, farmer harvest the crops and put it in special machine which break it into cellulose.

After that, the cellulose is moved to laps and goes through many chemical process to become sugar. With some microbes added it will become Ethanol and it used as fuel in cars , trucks and aircrafts. these vehicles will produce crabon dioxide emissions and the cycle continue.

Task Achievement / Task Response: Band 5.0

You identify the main stages and the circular relationship between plant growth, ethanol use and carbon dioxide, which gives the response a relevant overview. However, the account is incomplete and some details are inaccurate or unclear: the diagram shows pre-processing to produce cellulose, followed by processing into sugars, but your description says a machine breaks the crops directly into cellulose and then refers vaguely to “many chemical process.” The role of sunlight and carbon dioxide in plant growth is mentioned, and the transport uses are included, but the return of carbon dioxide to the plants could be explained more precisely. The response is 15 words below the required minimum, which limits the detail you can provide. Develop the stages more fully and report them in sequence.

Coherence and Cohesion: Band 5.0

The response has a basic overall structure: an opening overview followed by a description of the production cycle. Sequencing expressions such as “Second” and “After that” help the reader follow the stages, and the final sentence returns to the cycle. However, progression is not consistently clear because several stages are compressed into long, loosely connected statements, particularly the sentence beginning “After that, the cellulose is moved to laps.” The overview also repeats information about carbon dioxide without clearly distinguishing its role in plant growth from emissions after fuel use. Paragraphing is limited, and punctuation and spacing sometimes interrupt the flow. Use one paragraph for the overview and separate paragraphs for the stages, with clear links between each transformation.

Lexical Resource: Band 5.0

You use some relevant process vocabulary, including “harvest,” “cellulose,” “microbes,” “fuel” and “emissions,” so the reader can identify the topic and several key stages. However, the range is limited and some word choices or spellings make the description difficult to interpret. “Laps” appears to be an inaccurate term for the processing facility, while “crabon” and “sunligh” are spelling errors; “nutrition” is also not the most suitable description of what plants produce. Phrases such as “special machine” and “many chemical process” are vague and repetitive rather than precise. Aim to use the diagram’s labels consistently, such as “pre-processing,” “processing facility” and “sugars,” and check spelling and collocations before finishing.

Grammatical Range and Accuracy: Band 4.5

You attempt both simple and linked sentences, and the sequence can generally be understood. However, grammatical errors are frequent, and attempts to connect several stages often produce faulty structures. For example, “how it produced” is missing an auxiliary and uses an unsuitable tense, while “The process begin” has incorrect subject–verb agreement. In “farmer harvest the crops and put it,” the singular/plural forms and pronoun reference do not agree. Articles and sentence boundaries are also inconsistent, as in “With some microbes added it will become Ethanol and it used as fuel.” Use the present simple consistently for a process, check agreement and articles, and divide long sentences into complete clauses. These changes would make the stages easier to follow.
