The diagram shows six sequential stages at a Vietnamese recycling plant that turn used plastic bottles into reusable pellets, from collection through to storage and distribution.该图展示了越南一家回收工厂将废旧塑料瓶转化为可重复使用颗粒的六个连续阶段，从收集一直到储存与分发。
This 6.5 answer covers all six stages accurately but relies on a simple 'because' clause and generic details like 'dirt or labels' rather than the technical vocabulary ('sterilisation', 'contaminants') and combined sentence structures the 7.5 answer uses.这篇6.5范文准确覆盖了全部六个阶段，但依赖简单的 “because” 从句和 “dirt or labels” 这类笼统细节，而没有使用7.5范文中的专业词汇（“sterilisation”、“contaminants”）和组合句式。
The diagram shows the process of turning used plastic bottles into reusable pellets at a recycling factory in Vietnam, from collection to storage.该图展示了在越南一家回收工厂中，废旧塑料瓶被转化为可重复使用的塑料颗粒的过程，从收集到储存。
Overall, this is a linear process with six stages. It starts with collecting and sorting the bottles, and it ends when the finished pellets are stored and sent out for use.总体来看，这是一个包含六个阶段的线性流程。它从收集和分拣塑料瓶开始，到成品颗粒被储存并送出使用时结束。
First, plastic bottles are collected and then sorted. After that, they are washed and sterilised to remove any dirt or labels. This step is important because it makes the bottles clean before the next stage. Next, the clean bottles are shredded and ground into small pieces of plastic.首先，塑料瓶被收集起来，然后被分拣。之后，它们被清洗和消毒，以去除污渍或标签。这一步很重要，因为它能让瓶子在进入下一阶段之前保持洁净。接着，洁净的瓶子被粉碎并研磨成小块塑料。
Then, these small pieces are melted, and they are also filtered at the same time to remove any remaining dirt. After this, the melted plastic is turned into small pellets and left to cool down. Finally, the pellets are stored and then sent out so that they can be used again in manufacturing.然后，这些小块塑料被熔化，同时也被过滤以去除残留的污物。之后，熔化的塑料被制成小颗粒并冷却。最后，这些颗粒被储存，然后送出，以便再次用于制造业。

- TR“Overall, this is a linear process with six stages. It starts with collecting and sorting the bottles, and it ends when the finished pellets are stored and sent out for use.” — Correctly identifies the process type, stage count, and the first and last stages, though in plainer wording than the 7.5 overview.准确说明了流程类型、阶段数量以及首尾两个阶段，但措辞比7.5范文的总览句更为朴素。
- LR“they are washed and sterilised to remove any dirt or labels” — "Washed and sterilised" is accurate but the supporting detail ("dirt or labels") is more generic than the 7.5 answer's technical term "contaminants".“washed and sterilised” 用词准确，但所给的细节（“dirt or labels”）比7.5范文中的专业词汇 “contaminants” 更笼统。
- GRA“This step is important because it makes the bottles clean before the next stage.” — A simple "because" clause is grammatically correct but far plainer than the 7.5 answer's appositive-plus-relative-clause construction.简单的 “because” 从句语法正确，但比7.5范文中同位语加定语从句的结构简单得多。
- CC“After that, they are washed and sterilised to remove any dirt or labels.” — The basic sequencing marker "After that" links stages clearly but is repeated rather than varied across the essay.基本的顺序标记词 “After that” 清晰地衔接了各阶段，但在全文中重复使用而非有所变化。
- TR“Finally, the pellets are stored and then sent out so that they can be used again in manufacturing.” — Correctly closes at the diagram's final stage, matching the process's actual endpoint.准确地在图表最后一个阶段收尾，与流程实际的终点相符。
This 7.0 answer introduces technical vocabulary such as 'contaminants' and a passive time clause with an appositive ('a process which breaks them down...'), but its sentences are still slightly less densely packed than the 7.5 answer's appositive-plus-relative-clause construction.这篇7.0范文引入了 “contaminants” 等专业词汇，以及带同位语的被动时间状语从句（“a process which breaks them down...”），但句子密度仍略逊于7.5范文中同位语加定语从句的结构。
The diagram illustrates how used plastic bottles are converted into reusable pellets at a recycling facility in Vietnam, covering the six stages from initial collection to final storage.该图展示了在越南一家回收设施中，废旧塑料瓶如何被转化为可重复使用的塑料颗粒，涵盖从初始收集到最终储存的六个阶段。
Overall, this is a linear process consisting of six stages, beginning with the collection and sorting of used bottles and finishing with the storage and distribution of the finished pellets for reuse.总体来看，这是一个由六个阶段构成的线性流程，从收集和分拣废旧瓶子开始，到成品颗粒被储存并分发以供再利用时结束。
In the first stage, plastic bottles are collected and sorted, before being washed and sterilised in order to remove contaminants such as labels and food residue. Once this cleaning stage is complete, the bottles are shredded and ground, a process which breaks them down into smaller, more manageable fragments of plastic ready for further treatment.在第一阶段，塑料瓶被收集和分拣，随后被清洗和消毒，以去除标签和食物残渣等污染物。清洁阶段完成后，瓶子被粉碎并研磨，这一过程将它们分解成更小、更易处理的塑料碎片，为进一步处理做好准备。
These fragments are then melted, with filtering carried out at the same time to eliminate any remaining impurities. The resulting molten plastic is formed into small, uniform pellets during the pelletisation stage and subsequently allowed to cool. Finally, once cooled, the finished pellets are stored before being distributed for use in manufacturing across Vietnam.这些碎片随后被熔化，同时进行过滤以消除任何残留的杂质。所得的熔融塑料在造粒阶段被制成均匀的小颗粒，随后被冷却。最后，冷却后的成品颗粒被储存，然后被分发用于越南各地的制造业。

- TR“Overall, this is a linear process consisting of six stages, beginning with the collection and sorting of used bottles and finishing with the storage and distribution of the finished pellets for reuse.” — A well-formed overview that names the process type, stage count, and bookends it with first and last stages, close to the 7.5 model.一个结构良好的总览句，说明了流程类型、阶段数量，并用首尾阶段将其框定，接近7.5范文的写法。
- LR“before being washed and sterilised in order to remove contaminants such as labels and food residue” — Uses the technical term "contaminants" accurately, showing stronger topic-specific lexical resource than the 6.5 answer's generic "dirt or labels".准确使用了专业词汇 “contaminants”，比6.5范文中笼统的 “dirt or labels” 展现出更强的主题词汇能力。
- GRA“Once this cleaning stage is complete, the bottles are shredded and ground, a process which breaks them down into smaller, more manageable fragments of plastic ready for further treatment.” — A passive time clause followed by an appositive and relative clause packs two ideas into one sentence, echoing the 7.5 answer's structure.被动时间状语从句后接同位语和定语从句，将两层意思组织进一句话中，与7.5范文的结构相呼应。
- CC“These fragments are then melted, with filtering carried out at the same time to eliminate any remaining impurities.” — The "with + -ed clause" device links two simultaneous actions smoothly, a more sophisticated cohesive tool than the 6.5 answer's plain "and they are also".“with + 过去分词从句” 的手法流畅地衔接了两个同时发生的动作，比6.5范文中简单的 “and they are also” 更为高级。
- TR“Finally, once cooled, the finished pellets are stored before being distributed for use in manufacturing across Vietnam.” — Correctly closes at the diagram's final stage, with the added subordinate clause giving slightly more cohesion than a 6.5-level closing sentence.准确地在图表最后一个阶段收尾，所加入的从句比6.5水平的结尾句多提供了一些连贯性。
This 7.5 answer is distinguished by its precise technical vocabulary ('sterilisation', 'contaminants') and by packing a passive relative clause into an appositive noun phrase ('a process during which they are also filtered...'), giving it noticeably more sophisticated sentence construction than the lower bands.这篇7.5范文的突出之处在于精准的专业词汇（“sterilisation”、“contaminants”），以及将被动定语从句嵌入同位语名词短语中（“a process during which they are also filtered...”），使其句式结构明显比低分档更为精致。
The diagram illustrates the process by which used plastic bottles are converted into reusable pellets at a recycling facility in Vietnam, such as those operating in the industrial zones of Binh Duong and Dong Nai province.该图展示了在越南回收工厂（例如平阳省和同奈省工业区内运营的工厂）中，废旧塑料瓶被转化为可重复使用颗粒的过程。
Overall, the process comprises six distinct, entirely linear stages, beginning with the collection and initial sorting of used bottles and culminating in the storage and distribution of the finished recycled product.总体而言，该过程包含六个不同的、完全线性的阶段，始于废旧瓶子的收集与初步分类，最终以成品回收产品的储存和分发结束。
Initially, plastic bottles are gathered and subsequently sorted, presumably by type or colour, to prepare them for further processing. Following this, they undergo a thorough washing and sterilisation procedure, which is crucial for removing any contaminants such as food residue or labels. Once cleaned, the bottles are subjected to shredding and grinding, transforming them into smaller, more manageable plastic fragments.最初，塑料瓶被收集并随后进行分类，可能是按类型或颜色划分，以便为进一步加工做好准备。接下来，它们经过彻底的清洗和消毒程序，这对于去除食物残渣或标签等污染物至关重要。一旦清洗干净，这些瓶子就会被切碎和研磨，转变为更小、更易于处理的塑料碎片。
The subsequent stage involves melting these plastic fragments, a process during which they are also filtered to eliminate impurities. This molten plastic is then moved to the pelletisation and cooling phase, where it is formed into small, uniform pellets and allowed to solidify. Finally, these newly formed recycled plastic pellets are prepared for storage and distribution, making them ready for reuse in manufacturing across Vietnam's growing plastics industry.随后的阶段涉及将这些塑料碎片熔化，在此过程中它们也会被过滤以去除杂质。然后，这种熔融塑料被转移到造粒和冷却阶段，在这里它被制成小而均匀的颗粒并使其固化。最后，这些新形成的回收塑料颗粒被准备好进行储存和分发，以便在越南日益发展的塑料产业中被重新利用。
