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 diagram char illustarts how a biofuel called ethanol is produced and how ethanol is made.

Overall, it is clear that there are about 9 main process for made ethanol in the biofuel production, a large number of plants and trees are at the start point and finishe by supplying ethnol for transporation and gas mission.

At the first stage in the process of making ethnol a local number of trees and plants are grow at the start line and its safety to cover with sunlight and carbon dioxide.From human, transform by tricter in trees and plants to cutting at two machine.there machine trying to make pieces which called pre-processing to cut plants for made ethanol.

In the following stage, the second step is that strock some cellulose for strive to reach out processing. the figures showed mix some spieace to made sugar. subsequently, that attached with microbes that is added from craitiea. in addition, after that the final stage of process which that tranfer for three different electronic machiners such as, car, airplan and track for easily to tranfer ethanol.that is bottom part of process to over end.

Task Achievement / Task Response: Band 5.0

You identify the subject and give an overview of the cycle, noting that plants and trees are at the beginning and ethanol is ultimately used for transport. However, the account only partially covers the diagram and several stages are unclear or inaccurately described. For example, the diagram shows sunlight and carbon dioxide supporting plant growth, followed by harvesting, pre-processing into cellulose, processing into sugars, and the addition of microbes before ethanol is produced. These links are not reported reliably: “mix some spieace to made sugar” does not explain the processing stage, and the return of carbon dioxide from transport to the plants is largely omitted. Focus on accurately describing the main stages and the cycle, rather than adding unclear details.

Coherence and Cohesion: Band 5.5

There is a basic attempt to organise the response into an introduction, an overview and two body paragraphs. Sequencing phrases such as “At the first stage” and “In the following stage” help signal movement through the process. However, progression is difficult to follow because several sentences contain unclear or disconnected ideas, including “From human, transform by tricter in trees and plants” and “that is bottom part of process to over end.” Some linking expressions, such as “in addition” and “subsequently,” do not make the relationships between stages clear. Improve cohesion by giving each paragraph a clear purpose and describing each stage in order, using simple links such as “next,” “then” and “finally” accurately.

Lexical Resource: Band 4.5

The response includes some task-related vocabulary, including “biofuel,” “carbon dioxide,” “cellulose,” “microbes” and “transportation,” showing an attempt to describe the process. However, the range is limited and many word choices or spellings make the meaning difficult to recover, for example “ethnol,” “tricter,” “spieace” and “electronic machiners.” Some phrases are also unsuitable or unclear, such as “a local number of trees” and “gas mission.” Use the labels in the diagram directly and choose precise process vocabulary: for instance, describe plants being harvested, processed into sugars, and converted into ethanol. Careful spelling and natural collocations would make the account much clearer.

Grammatical Range and Accuracy: Band 4.5

You attempt to use both simple and longer sentences, and the overview begins with a suitable structure: “Overall, it is clear that…”. However, control of sentence structure is inconsistent, and errors frequently make relationships between ideas hard to understand. Examples include “there are about 9 main process for made ethanol,” “plants and trees are grow,” and “that attached with microbes that is added.” These show problems with plural forms, verb forms, agreement and sentence construction. Punctuation also needs attention: several sentences run together without spaces after full stops, as in “carbon dioxide.From human” and “ethanol.that is.” Practise building accurate short sentences first, then connect them with a clear subordinate clause where appropriate.
