TOEFL TPO -1 Writing Task 1 Sample: The article insists that device called an Ocean Cleanup Array could collect and remove the plastic debris from the oceans efficiently and lists three explanations how it will work. However, the speakers respectively contradicts the article by using three specific points as supports. Firstly, the passage contends that comparing with other ocean cleanup method, the OCA is about 30 times less expensive per unit of plastic removed which cost less. Contrarily, the speaker rebuts that 400 million dollars is only start, we need to put more since there are thousands of plastic going to ocean every year which means we need to buy more than 1 device, may be hundreds or thousands. What's more, the chemicals substance on the ocean do damage to the device, we need put a huge budget to repair it. There is no way the OCA can be the cheap way. Besides, the passage points out that due to the floating barriers of the OCA are solid and fixed, they won't catch any marine animals and hurt them. However, the speakers holds an opposite opinion. He states that natural ocean currents not only will carry the plastic toward the barriers but also the plankton a tiny ocean marine life.Since many marine animals prey on the plankton, the decline of the plankton would have negative impact on the ocean ecosystem. Last, the passage deems that Plastic collected from the ocean can be recycled and be sold to recycling facilities. Still, the speaker thinks differently, he argues that plastic debris already mixed up with the ocean organism, they need to be separated which cost lots. The recycling facilities won't buy the debris since the separation procedure is expensive.

22. 3.任务完成度

你的文章在任务完成度方面表现不错，基本上涵盖了阅读和听力材料中的主要观点。但是，你可以更加明确地表达出阅读和听力材料之间的对比关系。例如，在提到成本时，可以强调听力材料中提到的维修费用以及购买多个设备的必要性。

改进建议：

• 更明确地表达出阅读和听力材料之间的对比关系。

• 在提到成本时，强调听力材料中提到的维修费用以及购买多个设备的必要性。

示例：

1. Instead of saying "There is no way the OCA can be the cheap way," you could say, "The speaker argues that the initial cost of $400 million per device is just the beginning, as additional expenses for frequent repairs and the need for multiple devices would make it a costly solution."

2. Instead of saying "The recycling facilities won't buy the debris since the separation procedure is expensive," you could say, "The speaker points out that recycling facilities may not be interested in buying ocean plastics due to the high costs associated with separating and cleaning them."

4.文章结构与组织 在文章结构与组织方面，你需要加强段落之间的衔接和逻辑性。尝试使用更多的过渡词汇来连接不同的观点。此外，你可以在文章开头写一个简短的引言，总结阅读和听力材料的主要观点。

改进建议：

• 使用更多的过渡词汇来连接不同的观点。

• 在文章开头写一个简短的引言，总结阅读和听力材料的主要观点。

示例：

1. In the introduction, you could write, "The reading passage presents the Ocean Cleanup Array as an efficient and environmentally friendly solution to remove plastic debris from the oceans, while the listening passage challenges this view by highlighting several concerns."

2. To improve coherence and cohesion, you could use transition words like "Furthermore" or "On the other hand" to connect different points. For example, "Furthermore, the speaker disagrees with the claim that OCA has minimal impact on marine life."

Section Title: 6.文章修订

The article presents the Ocean Cleanup Array (OCA) as an efficient and cost-effective solution for removing plastic debris from the oceans. It highlights three main advantages of the OCA: cost, minimal impact on marine life, and recycling potential. However, the speaker in the listening passage raises several concerns that challenge these claims.

Firstly, the article asserts that the OCA is a relatively inexpensive method for ocean cleanup, costing around 400 million dollars per device and being 30 times less expensive per unit of plastic removed compared to other methods. In contrast, the speaker contends that this initial cost is just a starting point, as thousands of devices may be needed to effectively clean up the vast amount of plastic entering the oceans each year. Additionally, he points out that due to corrosive chemicals and strong mechanical forces in ocean waters, devices like OCA are prone to damage and would require frequent repairs at significant expense.

Secondly, while the article argues that solid floating barriers of OCA would have minimal impact on marine life since swimming animals can easily avoid them without getting caught or trapped, the speaker disagrees. He emphasizes that natural ocean currents would not only carry plastic towards these barriers but also plankton - tiny marine organisms that many sea animals rely on as a food source. Consequently, removing large amounts of plankton from oceans could have detrimental effects on entire ocean food chains.

Lastly, regarding recycling potential, the article suggests that plastics collected by OCA can be sold to recycling facilities as they are primarily composed of polyethylene and polypropylene - materials easily processed by such plants. The speaker counters this claim by explaining that plastics collected from oceans are often mixed with sea organisms and broken down into small pieces which need to be separated before recycling. This separation process adds considerable costs for recycling facilities, making them less likely to purchase ocean plastics.

In light of these counterarguments presented by the speaker, it becomes evident that the Ocean Cleanup Array may not be as efficient, environmentally friendly, or cost-effective as initially suggested by the article. (353 words)

Revised essay: Section Title: 7. Article Revision

The article presents the Ocean Cleanup Array (OCA) as an efficient and cost-effective solution for removing plastic debris from the oceans, highlighting three main advantages of the OCA: cost, minimal impact on marine life, and recycling potential. However, the speaker in the listening passage raises several concerns that challenge these claims. (Changed "文章修订" to "Article Revision" for a more accurate translation.)

Firstly, the article asserts that the OCA is a relatively inexpensive method for ocean cleanup, costing around 400 million dollars per device and being 30 times less expensive per unit of plastic removed compared to other methods. In contrast, the speaker contends that this initial cost is just a starting point, as thousands of devices may be needed to effectively clean up the vast amount of plastic entering the oceans each year. Additionally, he points out that due to corrosive chemicals and strong mechanical forces in ocean waters, devices like OCA are prone to damage and would require frequent repairs at significant expense.

Secondly, while the article argues that solid floating barriers of OCA would have minimal impact on marine life since swimming animals can easily avoid them without getting caught or trapped, the speaker disagrees. He emphasizes that natural ocean currents would not only carry plastic towards these barriers but also plankton - tiny marine organisms that many sea animals rely on as a food source. Consequently, removing large amounts of plankton from oceans could have detrimental effects on entire ocean food chains.

The speaker counters this claim by explaining that plastics collected from oceans are often mixed with sea organisms and broken down into small pieces which need to be separated before recycling.

In light of these counterarguments presented by the speaker, it becomes evident that the Ocean Cleanup Array may not be as efficient, environmentally friendly, or cost-effective as initially suggested by the article.
