IELTS Writing Task 1 question

The diagram below shows the process for recycling plastic bottles.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

How plastic bottles are recycled

Student answer (Band 6.0)

The given below are the process recycling plastic bottles.

Looking from an overall perspective it is crystal clear that, the diagram below, contain 9 steps starting from throwing plastic bottles to dustbin and ended with the production of new products from waste bottles.

When people throw plastic bottles into dustbin then the collection truck collect all that waste plastic bottales, and sent to a recycling centre where the bottales get sorted onn the bases of there conditions. After sorting done the plastic bottales are compressed into block then that block is sent to crusher machine for crushing.

After the crushing has done the pieces than washed and sent to a machine for producing plastic peliets, after formation of peilets, they are heated to form a raw material. At last, the raw material is converted to a new products. Here this process ends and to form more new products, this process repeats.

Task Achievement / Task Response: Band 6.0

You cover the main sequence from disposal and collection through sorting, compression, crushing, washing, pellet production and heating into raw material. The overview also identifies the nine stages and the circular nature of the process, which is important. However, some features are less fully reported: the sorting stage separates acceptable bottles from rejected items, and the final products include several examples, such as containers, clothing and bags. The ending, “the raw material is converted to a new products,” is also less precise than the diagram, which shows raw material being used to produce end products before the cycle returns to the bin. Include these details to make the account more complete.

Coherence and Cohesion: Band 6.5

The response follows the process in a clear chronological order, and the paragraphing separates the overview from the detailed stages. Linking expressions such as “After sorting,” “After the crushing” and “At last” help the reader follow the sequence. The final sentence also signals the return to the start of the cycle. This is a coherent overall arrangement, though some connections are mechanical or unclear: “After the crushing has done the pieces than washed” makes the transition difficult to follow, and “Here this process ends and to form more new products, this process repeats” is awkwardly joined. Use clearer sentence boundaries and refer explicitly to the cycle returning to bottle disposal.

Lexical Resource: Band 5.5

You use relevant process vocabulary, including “compressed,” “crusher machine,” “washed,” “pellets” and “raw material,” so the stages are generally understandable. There is also some useful variation in describing the sequence. However, spelling errors such as “bottales,” “onn,” “peliets” and “peilets” are noticeable, and several expressions are imprecise or unnatural, including “dustbin,” “on the bases of there conditions” and “new products.” Prefer accurate diagram-related terms such as “recycling bin,” “sorted according to condition” and “end products.” More precise collocations and careful spelling would make the description clearer and more appropriate for an academic process report.

Grammatical Range and Accuracy: Band 5.0

You attempt both simple and complex sentences, for example, “When people throw plastic bottles into dustbin then the collection truck…” and the sequence beginning “After the crushing…”. The overall meaning can usually be followed, but some sentence structures and verb forms are faulty. In “the collection truck collect … and sent,” the subject–verb agreement and verb forms do not match; “After sorting done” needs a complete passive construction, and “the pieces than washed” lacks a correctly formed verb phrase. Articles and plurals also need attention in “into dustbin” and “a new products.” Practise accurate passive forms for process descriptions, such as “the bottles are collected” and “the pieces are washed,” while checking agreement and sentence punctuation.
