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 5.5)

The diagram illustrates a procedure about an important biofuel called ethanot . overall it faces different kind of stages start from planting tress to finally produced ethanol and using at vast number of transportation and back again to the nature .

first of all , it start it's journey from giving the sunlight and carbondioxide to the nature . Meanwhile ,help of this people plant tree and crops . beside eating these crops going under a pre processing unit and extract its cellulose . after that this cellulose go through a processing factory where not only its going under a chamical reaction but also sugars are finally came out

to be specific , these sugers are pre stage of ethanol . before it convert with an ethanot only one ingridient is left which called microbs , these microbs make ethanol and these ethanol is used as a fuel for car , truck and many others purposes

compareing this diagram , it is clear that the procedure is make a huge role in our nature and it helps us to continue our living .

Task Achievement / Task Response: Band 5.5

You identify the process as ethanol production and mention several central stages, including plant growth, pre-processing, cellulose, processing, sugars, microbes and transport use. However, the account is only partial: it does not clearly explain that carbon dioxide released by the vehicles returns to support plant growth, which is essential to the cycle shown. The opening overview says the process starts with planting, whereas the diagram begins with sunlight and carbon dioxide enabling plants and trees to grow. Some details are also unclear, such as what happens during pre-processing and how microbes contribute to producing ethanol. To strengthen the response, give a precise overview of the circular nature of the process, then describe the stages and the carbon-dioxide loop accurately.

Coherence and Cohesion: Band 5.5

The response has a basic sequence, moving from plant growth through processing to ethanol use, and paragraph breaks provide some organisation. However, progression is not consistently clear: the first paragraph gives a broad overview, while later stages are compressed into long sentences, making the relationships between them difficult to follow. Connectors such as “first of all,” “after that” and “to be specific” help signal order, but some are awkward or do not clarify the process. The final paragraph begins “compareing this diagram” without making a comparison, and it does not complete the cycle back to plant growth. Use one paragraph for the overview and separate paragraphs for production and the return loop, with clear stage-to-stage links.

Lexical Resource: Band 5.0

You use some relevant process vocabulary, including “cellulose,” “processing factory,” “sugars,” “microbs” and “fuel,” so the topic is generally recognisable. However, the range is limited and several spelling and word-choice errors make the description less precise, including “ethanot,” “tress,” “sugers” and “ingridient.” Phrases such as “giving the sunlight and carbondioxide to the nature” and “make a huge role” are not natural collocations. There is also repetition of “ethanol” and “these crops” where more exact references would help. Build a reliable set of process terms and use accurate verbs such as “release,” “convert” and “return” to describe the stages and cycle.

Grammatical Range and Accuracy: Band 5.0

You attempt some longer structures, for example “where not only its going under a chamical reaction but also sugars are finally came out,” but the construction is faulty and obscures the relationship between the ideas. Errors in verb forms and agreement occur throughout: “it start,” “these cellulose go,” “these microbs make,” and “these ethanol is used.” Sentence boundaries and punctuation are also inconsistent, with spaces before commas and several run-on sentences. These problems sometimes make the process difficult to follow, despite the reader being able to infer the general topic. Practise accurate present-simple descriptions of processes, checking subject–verb agreement and using passive forms where appropriate, such as “the cellulose is processed” and “sugars are produced.”
