6.文章修订

The reading passage explores the issue of lowering the salinity in the Salton Sea, while the professor's lecture casts doubt on the practicality and feasibility of the proposed solutions. The lecture provides three specific points that contradict the suggestions in the reading.

Firstly, although the reading passage proposes using desalination facilities to reduce salinity, the professor argues that this method may cause other serious problems. She explains that during evaporation, dissolved materials and harmful chemicals could be released into the air. When wind blows, these chemicals may pose a threat to people's health. This argument from the professor undermines the solution presented in the reading.

Secondly, despite the reading's suggestion to use canals and pipelines to bring ocean water into the lake, the professor contends that local government may lack resources to fund such a massive project. She supports this point by highlighting that constructing canals or pipelines over a 100-kilometer distance between the lake and ocean would be prohibitively expensive. In other words, this solution is not practical.

Lastly, while the reading claims that constructing walls would help separate different sections of salinity within the lake, the professor asserts that these walls would not be a long-lasting solution due to frequent earthquakes in that region. She points out that even if this method proves effective for a short period of time, walls are likely to collapse during an earthquake, causing water with varying levels of salinity to mix again.

In light of these points raised by the professor, it becomes evident that she has identified weaknesses in each proposed solution from the reading passage and convincingly demonstrated their impracticality or ineffectiveness in addressing Salton Sea's increasing salinity problem. (280 words)

3. Grammar

The reading and the lecture are both about solutions to reverse the trend of salinity. The author of the reading passage provides three waysways,(This rule identifies whether commas are missing in a sentence.) while the lecturer identifies weaknesses of them all.

To begin with, the author argues that one method is to remove salt of the lake directly. However, the professor rebuts in the lecture that it might cause dangerous chemicals which are probably blown into the air and do harm to people's health.

Secondly, even though the author suggests that we can dilute the salt level by bringing ocean water into the lake, the professor mentions the unaffordable enpenseexpense(misspelling) of pipulinespipelines(misspelling) in result of the one-kilometer distance between the ocean and the sea, which contradicts the possibility for the local government to tale this advice.

Finally, the author posits that, aiming at directing all the freshwater in the area into one main section of the lake i the use of consturctingconstructing(misspelling) walls, dividing the lake into several sections can control the salinity whereas the professor asserts that it is not a long-term solution since there may be geological activities such as earthquake destroying the walls, convincingly displaying that this means does not make sense.

6. Revised Essay

The reading passage and the lecture both discuss potential solutions to address the increasing salinity of the Salton Sea in California. The author of the reading passage proposes three methods to combat this issue, while the lecturer casts doubt on each of these solutions by highlighting their weaknesses.

Firstly, the reading suggests that desalination facilities could be employed to remove salt directly from the lake's water. However, the lecturer contends that this approach might lead to hazardous consequences. The desalination process would leave behind solid materials, including toxic chemicals such as selenium. If these chemicals were dispersed into the air by wind and subsequently inhaled by people, it could pose significant health risks.

In addition, the author proposes diluting the lake's salt levels by introducing ocean water through pipelines or canals. The lecturer challenges this solution by emphasizing the prohibitive costs associated with constructing such infrastructure. Given that the nearest Pacific Ocean shoreline is located 100 kilometers away from the Salton Sea, building pipelines or canals over such a vast distance would be extremely expensive and likely unaffordable for local government resources.

Lastly, dividing the lake into sections using walls is presented as another potential solution in the reading passage. This method aims to control salinity by directing all freshwater from nearby rivers into one main section of the lake while allowing salinity levels to increase in smaller sections. However, the lecturer disputes this approach's effectiveness as a long-term solution due to frequent geological activity in the region, such as earthquakes. These natural events could potentially destroy constructed walls, causing high-salinity water from separated sections to mix back with low-salinity water in the main section.

Overall, although each proposed solution in the reading passage appears promising at first glance, their feasibility is undermined by various concerns raised during the lecture. Consequently, alternative strategies may need to be explored to effectively address and reverse increasing salinity levels within California's Salton Sea. (323 words)

Section Title: 6.文章修订

The passage introduces the issue of increasing salinity in the Salton Sea, which could potentially turn the lake into a dead zone, and proposes three solutions to address this problem. While the lecturer agrees that reducing salinity is essential, she casts doubt on the effectiveness of these solutions as presented in the reading.

Firstly, the reading passage suggests that salt can be removed using special desalination facilities which heat the lake water, leaving salt behind. However, the lecturer contends that this approach has significant drawbacks. She points out that although these facilities could reduce the salt levels in the lake, they may not restore its overall health. This is because during desalination, solid materials containing toxic chemicals are left behind, posing a danger to both humans and wildlife. Thus, instead of benefiting the lake's health, this solution may have negative consequences.

Secondly, according to the passage, diluting the lake's salinity with ocean water is another viable solution. The lecturer disputes this claim by arguing that implementing such a solution would be prohibitively expensive for local government resources. She explains that since the nearest ocean shoreline is approximately 100 kilometers away from the lake, constructing pipelines or canals over such long distances would be financially unfeasible.

Lastly, building walls to divide up sections of Salton Sea is proposed in order to control salinity levels within its main section. The lecturer casts doubt on this solution's long-term effectiveness by highlighting potential issues with geological activity in the region. She explains that earthquakes are common occurrences in this area and could easily destroy these walls causing them to collapse and allowing high-salinity water from separated sections to mix back into low-salinity water from main section.

In conclusion, while all three solutions presented in reading passage aim at addressing increasing salinity levels in Salton Sea they are not without their drawbacks as pointed out by lecturer making them less feasible and effective than initially suggested. (324 words)

Section Title: 6.文章修订

The reading passage and the lecture both discuss potential solutions to prevent the increasing salinity of the Salton Sea in California. The reading passage presents three proposals: using desalination facilities, diluting the lake with ocean water, and constructing walls to separate sections of the sea. However, the professor systematically refutes each of these points in the lecture.

Firstly, contrary to the writer's idea that desalination facilities could help slow down the trend of increasing salinity, the professor states that this approach would yield additional problems. While water from the sea evaporates in desalination facilities, toxic solid materials are left behind. These chemicals pose a health risk when people breathe them in.

Furthermore, the professor discredits the reading's assertion that diluting Salton Sea water with ocean water through pipelines and canals is a viable solution. The professor explains that local governments likely lack sufficient resources to construct such infrastructure due to its high cost and long distances involved.

Lastly, while the author suggests that constructing walls to divide sections of the lake could be helpful, the speaker highlights an issue with this approach. The region experiences frequent geological activity, such as earthquakes. Inevitably, these events would cause wall collapse and lead to mixing between high-salinity sections and low-salinity main sections.

A clear divide exists between both perspectives regarding approaches to prevent further salinization of Salton Sea. (228 words)

Lastly, while the author puts forward that the suggests that constructing walls dividing to divide sections of the lake could be helpful, whereas in view of the speaker, the speaker highlights an issue with this approach (revised for natural tone). The region are suffered from active experiences frequent geological activities, activity, such as the earthquakes. In the long run, the walls will be collapsed ande the section divided by the walls earthquakes (revised for clarity). Inevitably, these events would converge to the cause wall collapse and lead to mixing between high-salinity sections and low-salinity main sections as well. ¶ An apparent (revised for clarity).

A clear divide exists between both perspectives regarding the approach to avoid the sea to be more salty.approaches to prevent further salinization of Salton Sea (revised for natural tone).
