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 illustrates the procedure of production of ethanol (a biofuel).The process is approxiately of about 9-10 steps.

It can be clearly seen that the production of ethanol is a process which takes place in a cycle that keeps on repeating. The making of ethanol begins when plants that grow in their natural environment and absorb sunlight as well as CO2 in form of energy. These plants and tress are then harvested by farmers which are futher sent for pre processing. Followed by this step, cellulose is attained from plants which is processed later to turned in form of sugars.

The nest step is to introduce other microbes to the sugars processed from cellulose. This gives us our desired product which is Ethanol, however the procedure does not stop here.

This ethanol if further used as fuel in cars, trucks in fact in airplnes, which produces CO2 .These machines are then used by humans and release CO2 which is again absorbed by the plants and trees , subsequently the cycles goes on.

Task Achievement / Task Response: Band 6.0

You identify the diagram as a repeating cycle and cover the main stages from plant growth through processing to ethanol use and carbon dioxide returning to plants. This gives the reader a relevant overview, and the references to cars, trucks and aeroplanes reflect the diagram. Some details, however, are less fully or precisely reported: the opening says there are “9-10 steps” without clarifying the stages, and “plants that grow in their natural environment” adds information not shown. The account also does not clearly explain that sunlight and carbon dioxide support plant growth, or that the three transport modes release carbon dioxide into the cycle. A more precise overview and clearer description of these relationships would make the key features more complete.

Coherence and Cohesion: Band 6.0

The response follows the process in a generally logical order, and the paragraph break before “The next step” helps separate the production stages from the later use of ethanol. Linking expressions such as “Followed by this step,” “however,” and “subsequently” also show an effort to connect ideas. At times, though, these links are mechanical or unclear: “Followed by this step” does not smoothly introduce the next stage, while “These machines” could refer to the vehicles or to something else. The first paragraph also contains several stages in one long sequence. Use clearer stage-to-stage transitions and divide the process into more balanced sections so that progression and reference are easier to follow.

Lexical Resource: Band 5.5

You use relevant process vocabulary, including “harvested,” “cellulose,” “microbes,” and “absorbed,” which helps communicate the diagram’s stages. There is also some useful variation in referring to the product as “ethanol” and “biofuel.” However, several word choices and collocations are imprecise, such as “the procedure of production,” “attained from plants,” and “processed later to turned in form of sugars.” Spelling errors, including “approxiately,” “tress,” “futher,” “nest,” and “airplnes,” also reduce accuracy. Aim for concise, standard process language and proofread carefully; more precise verbs such as “converted” and “released” would make the description clearer and more natural.

Grammatical Range and Accuracy: Band 5.5

You attempt both simple and complex sentence forms, including a relative clause in “plants that grow in their natural environment” and a contrast introduced by “however.” The sequence remains understandable overall, but some grammatical errors affect clarity. For example, “The making of ethanol begins when plants … absorb” is followed by a sentence fragment, and “which is processed later to turned” has an incorrect verb pattern. There are also agreement and article problems in “the cycles goes on,” as well as punctuation issues where sentences run together after “biofuel)” and “CO2.” Check that each sentence has a complete main clause, use the correct verb form after “to,” and review subject–verb agreement and sentence boundaries.
