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 presented figure demonstrates the method for recycling plastic bottles.

Overall, it can be witnessed that bottles recycling process quite lenghty. Which is consist of nine specific steps.

To commence with, in first step plastic bottles are throw in basket. Where heavy vechile transported these bootles from basket to recycling centre. Furthermore, at this stage bottles are seprated into two boxes, in one box perfect bootles keep and other container damage bottle placed with the help of human power. In addition, these good bottles compress and these are formed into blocks shape.After that, blocks kept in crusher and converted into small pieces and wash these pieces with water in seprate container.

Further analyzing the process, it can be noticed that small pieces are changed into plastic pellets with the help of machine. Moreover, these pellets are heated and send to next stage to form of raw material. Finally, the raw material is ready to produce end products.

Task Achievement / Task Response: Band 6.5

You cover the main sequence from putting bottles in a bin through sorting, compressing, crushing, washing, pellet production and heating. The overview also identifies a nine-step process, and the details about sorting bottles into acceptable and rejected groups and turning them into blocks are relevant. This gives the reader a sound account of the early and middle stages. However, the final part is less fully reported: the diagram shows the raw material being used to make several end products, and the process then loops back to the recycling bin. Your response stops at saying the material is ready to produce products, so it omits both the examples and the circular return. Include these features to make the coverage more complete and precise.

Coherence and Cohesion: Band 6.5

The stages are presented in a generally logical order, and phrases such as “To commence with,” “After that,” and “Finally” help signal progression. The division into an overview and process description also gives the response a recognisable structure. This is a coherent overall arrangement, although some links are mechanical and a few sentence boundaries interrupt the flow. For example, “Overall, it can be witnessed that bottles recycling process quite lengthy. Which is consist of nine specific steps” separates a dependent idea into a fragment. The transition “Further analyzing the process” is also unnecessary because the sequence itself is clear. Use fewer formulaic transitions, connect related stages within complete sentences, and add a final link showing that end products return to the start of the cycle.

Lexical Resource: Band 5.5

You use relevant process vocabulary, including “recycling centre,” “separated,” “compress,” “blocks,” “crusher,” “pellets,” and “raw material,” so the stages are usually identifiable. There are also attempts to vary wording, such as “To commence with” and “Further analyzing.” However, spelling and word-choice errors are noticeable and sometimes make the description less natural: “lenghty,” “vechile,” “bootles,” and “seprated” are misspelled, while “basket” and “heavy vehicle” are less precise than “recycling bin” and “collection truck.” Some combinations are awkward, including “perfect bottles” and “with the help of human power.” Build accuracy with the diagram’s specific terms and practise spelling them; choose natural collocations such as “acceptable bottles are retained” and “the truck transports them.”

Grammatical Range and Accuracy: Band 5.0

The response attempts both simple and more developed sentence patterns, including a sequence joined with “Furthermore” and a passive construction in “these pellets are heated.” However, control is uneven, and several errors affect sentence completeness and clarity. “Which is consist of nine specific steps” is a fragment and combines an incorrect verb form; “plastic bottles are throw” also needs a correct passive form. Other examples include “these good bottles compress” and “the raw material is ready to produce end products,” where the intended subject-action relationship is unclear. Articles and sentence boundaries also need attention. Practise forming accurate passives for process descriptions—for example, “the bottles are sorted” and “the blocks are crushed”—and check that each sentence has a complete main clause. More reliable control of these patterns would improve readability.
