The debate regarding decreasing the salinity of the Salton Sea is addressed by both the author and the professor. In the reading passage, the author presents three solutions for desalination. Nevertheless, the professor effectively casts doubt on each solution made in the reading passage by providing alternative perspectives and highlighting potential negative consequences, indicating it is neither practical nor realistic. To begin with, in contrast to the author’s claim in terms of the direct removal of salt from the Salton Sea’s water by means of desalination facilities, the professor contends that it will present serious problems, specifically health risks. In detail, he points out the wind is going to bring toxic chemicals into the air, which are formed through water evaporating. Consequently, people breathe the polluted air in, leading to health problems. Moreover, the professor further challenges the author’s assertion that it is effective to dilute the salt level with water, using pipelines and canals. He argues that although it may work out, the expanse of constructing pipelines and canals is prohibitive, which the government could not pay for. In addition, the expanse of construction for such a long distance, 100 kilometers, to be more specific, is costly. Furthermore, while the author implies the way of constructing walls to separate the lake into several sections to control the salinity, the professor presents a dissenting view. He emphasizes that it is unlikely to work for a long time because there are frequent geological activities in the region, such as earthquakes, which are able to destroy the walls easily. As a result, the dividing walls are only effective for a short while before they collapse due to earthquakes.

The debate regarding the Salton Sea's salinity is addressed by both the author and the professor. In the reading passage, the author presents three solutions for desalination. However, the professor effectively casts doubt on each solution by providing alternative perspectives and highlighting potential negative consequences, indicating that they are neither practical nor realistic.

Firstly, in contrast to the author's claim of utilizing desalination facilities for direct salt removal from the Salton Sea's water, the professor contends that this approach would present serious health risks. Specifically, he explains that the desalination process would produce toxic chemicals like selenium, which could be spread by wind and pose a health risk to people who breathe them in.

Additionally, regarding the second solution proposed in the reading passage—diluting salt levels with ocean water using pipelines and canals—the professor argues that although it may work theoretically, its implementation is financially prohibitive. He emphasizes that constructing pipelines or canals over such a long distance (100 kilometers) would be costly and beyond local government resources.

Lastly, while the author suggests constructing walls to divide the lake into several sections as a means of controlling salinity levels, the professor presents a dissenting view. He emphasizes that this solution is unlikely to be effective long-term due to frequent geological activities in the region, such as earthquakes. Consequently, even if dividing walls were built successfully initially, they would likely collapse during an earthquake and render this solution ineffective in controlling salinity levels.

In light of these counterarguments presented by the professor during his lecture, it becomes evident that each of these proposed solutions has significant drawbacks or limitations that make them impractical or unrealistic for addressing salinity issues in California's Salton Sea. (283 words)

In the lecture, the professor casts doubts on several solutions to reduce the salinity in Salton Sea mentioned by the reading passage. The professor asserts that these solutions are not realistic or practical at all. Firstly, contrary to the belief in the passage that salt in the lake can be removed directly by heating the water to leave salt and other materials behind, the professor asserts that this practice could result in serious problems because those materials left behind including some toxic chemicals, if spread into other areas and breathed in by people, would be dangerous to people's health. Secondly, the author of the passage points out that ocean water could be delivered through pipelines or canals to dilute the salt level, while the lecture notes that the governments don't have enough resources to bulidbuild(misspelling) the device because it is too expensive to establish such long pipelines or canals, over 100 kilometers, (Two consecutive spaces)between Pacific Ocean and Salton Sea. Lastly, opposing the author's belief that constructing walls to divide the lake into several sections could control the lake's salinity, the professor contends that this solution would just work in a short period, considering the lake is located in the region where geographic activities like major earthquakes happen frequently, posing a significant threat towards the walls.

6.文章修订

The lecture casts doubt on the solutions proposed in the reading passage for addressing the increasing salinity of the Salton Sea in California. The reading passage suggests three potential solutions: desalination, bringing ocean water into the lake, and dividing the lake into sections with walls. However, the lecturer argues that these solutions are not realistic or practical due to various reasons.

Regarding the first solution of desalination, the lecturer contends that this method would pose significant health risks. Although desalination would reduce salinity by evaporating water and leaving behind solid materials, it would also produce toxic chemicals such as selenium. These hazardous substances could be dispersed by wind and inhaled by people, causing serious health issues.

The second solution proposed in the reading passage involves diluting the lake's salt levels with ocean water delivered through pipelines or canals. The lecturer disputes this solution by highlighting its financial impracticality. Constructing pipelines or canals over long distances would be prohibitively expensive, and it is uncertain whether local governments possess sufficient resources to fund such a project. Furthermore, the nearest shoreline of the Pacific Ocean is 100 kilometers away, exacerbating construction costs.

Lastly, the reading passage suggests controlling salinity by constructing walls to divide the lake into several sections. In smaller sections, salinity would be allowed to increase while freshwater from nearby rivers would flow into a larger main section to maintain lower salinity levels. The lecturer challenges this solution due to its vulnerability to geological activity in the region. Earthquakes are frequent occurrences near Salton Sea; thus, any constructed walls are likely to collapse during seismic events, causing high-salinity water from smaller sections to mix back with low-salinity water in the main section.

In summary, although well-intentioned, each of these proposed solutions faces significant challenges as presented by the lecturer. Desalination raises health concerns due to toxic chemicals produced in the process, bringing ocean water into the lake is financially impractical, and dividing the lake with walls is vulnerable to the region's geological activity. Consequently, alternative solutions must be explored to address the Salton Sea's increasing salinity and preserve its fish and bird populations. (353 words)

5. Grammar

The reading passage outlines three ways to reverse the trend (Two consecutive spaces)that the lake become too salty for fish and bird to live in, while the lecture refutes each of them sequentially. Firstly, the passage claims through the action directly removing salt from lake's water with special equipments and making water evaporate would solve the problem. However, the speaker challenge this notion, stating that after pumping and heating salty water, salt left behind might be toxic chemicals. If wind bring them into the air, they would be danger to the health. Secondly, the passage asserts that another possible solution is to dilute the salt level in the lake with water from the ocean as water in the ocean is 2o percent less salty than lake's water, decreasing the salinity of the lake. The speaker disputes this method by arguing that it is too expensive for the local government to build constructions to pump water from the Pacific Ocean because the distance is over 1000 kilometers away from the lake and the government cannot builtbuild(Non-infinitive verb after modal verbs) such long pump way. Lastly, the reading states that controlling lake's salinity with walls in several places can stop the trend continuing. The walls allow salinity in small area increase, while the salinity would be controlled in most large sections. Contrarily, the speaker maintains that the wall can't work long due to frequency and intense earthquakes which would damage the walls and water would run back into the main section.

6. Revised Essay

The reading passage presents three potential solutions to prevent the Salton Sea from becoming too salty for fish and bird populations to survive, while the lecture casts doubt on each of these proposals.

Firstly, the passage suggests that directly removing salt from the lake's water using special desalination facilities could resolve the issue. However, the speaker challenges this idea, arguing that after pumping and heating the salty water, toxic chemicals might be left behind along with the salt. If wind carries these chemicals into the air, they could pose a significant health risk.

Secondly, the passage proposes diluting the lake's salt levels with ocean water as a viable solution since ocean water is 20 percent less salty than lake water, thus decreasing salinity. The speaker disputes this method by pointing out that constructing pipelines or canals to transport water from the Pacific Ocean would be prohibitively expensive for local government due to its distance of over 100 kilometers from the lake.

Lastly, according to the reading, controlling salinity by constructing walls in several areas could halt this detrimental trend. These walls would allow salinity to increase in smaller sections while being controlled in larger areas. In contrast, the speaker asserts that such walls would not be effective long-term due to frequent and intense earthquakes in the region which could damage them and cause high-salinity water to mix back into main sections of the lake.

5. 语法批改

The mounting salinity, arising from water evaporation, is the focus of both the writer and the professor. In the writing, three solutions, involving processing by desalination facilities, diluting with ocean water and erecting walls, are elaborated. The professor, however, does not regard them as pragmatic methods. As opposed to the measure of separation, the professor points out that leaving solid stuff may undermine our general wholesomeness. To be more specific, such materials as selenium are probably toxic, leading to respiration health problems once enterit enter(This rule identifies whether the preposition 'it' is missing in a sentence.) the atmosphere. She continues to discredit the dilution method with the consideration of high expenses. She states that the distance between lakes and seas is long, hardly below 1 km, thus contributing to a major expenditure in the construction of pipelines and canals. It is the professor’s third argument that the walls, used for dividing lakes, may not last long, which are especially vulnerable to earthquakes. In this way, it is not a sensible choice to separate lakes with walls in the long term.

Section Title: 6.文章修订

The increasing salinity of the Salton Sea, resulting from water evaporation, is a concern for both the author and the lecturer. In the reading passage, three potential solutions are proposed: desalination facilities, diluting with ocean water, and constructing walls to divide the lake. However, the lecturer casts doubt on these solutions as being impractical.

Contrary to the desalination solution presented in the reading passage, the lecturer highlights that solid materials left behind during this process could pose health risks. Specifically, toxic substances such as selenium may be released into the atmosphere and cause respiratory health issues when inhaled.

Furthermore, the lecturer challenges the feasibility of diluting lake water with ocean water due to high costs associated with this approach. She emphasizes that constructing pipelines or canals over long distances (at least 100 kilometers) would require significant financial resources that may not be available to local governments.

Lastly, the lecturer disputes the effectiveness of building walls to divide sections of the lake as a long-term solution. She argues that since Salton Sea is located in an area prone to frequent geological activity like earthquakes, these walls would likely be destroyed by such events. Consequently, water from high-salinity sections would mix back into low-salinity areas, rendering this solution ineffective in maintaining distinct salinity levels within different sections of the lake.

The mounting salinity, arising increasing salinity of the Salton Sea, resulting from water evaporation, is the focus of a concern for both the writer and the professor. author and the lecturer (Changed "mounting" to "increasing" and "arising from" to "resulting from" for clarity). In the writing, reading passage, three solutions, involving processing by potential solutions are proposed: desalination facilities, diluting with ocean water and erecting walls, are elaborated. The professor, however, does not regard them water, and constructing walls to divide the lake (Rephrased "elaborated" to "proposed" for better word choice). However, the lecturer casts doubt on these solutions as pragmatic methods. being impractical.

As opposed to the measure of separation, the professor points out that leaving Contrary to the desalination solution presented in the reading passage, the lecturer highlights that solid stuff may undermine our general wholesomeness. To be more specific, materials left behind during this process could pose health risks (Changed "measure of separation" to "desalination solution" for clarity). Specifically, toxic substances such materials as selenium are probably toxic, leading to respiration may be released into the atmosphere and cause respiratory health problems once enter the atmosphere. issues when inhaled (Rephrased sentence for better readability).

Furthermore, the lecturer challenges the feasibility of diluting lake water with ocean water due to high costs associated with this approach (Changed "discredit" to "challenges" and rephrased sentence for clarity). She continues to discredit the dilution method with the consideration of high expenses. She states that the distance between lakes and seas is long, hardly below 1 km, thus contributing to a major expenditure in the construction of emphasizes that constructing pipelines and canals. ¶ It is the professor’s third argument that the walls, used for dividing lakes, or canals over long distances (at least 100 kilometers) would require significant financial resources that may not be available to local governments (Clarified distance measurement and rephrased sentence).

Lastly, the lecturer disputes the effectiveness of building walls to divide sections of the lake as a long-term solution (Changed "third argument that walls...may not last long, which are especially vulnerable to earthquakes. In long," to a more concise phrase). She argues that since Salton Sea is located in an area prone to frequent geological activity like earthquakes, these walls would likely be destroyed by such events (Clarified reasoning behind vulnerability). Consequently, water from high-salinity sections would mix back into low-salinity areas, rendering this way, it is not a sensible choice to separate lakes with solution ineffective in maintaining distinct salinity levels within different sections of the lake (Clarified outcome of walls in the long term.being destroyed).

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)

The passage introduces the topic issue of how to remove the salt from the lake , increasing salinity in the Salton Sea, which could make potentially turn the lake become into a dead zone, and lists proposes three solutions to handle that. 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 (The lecturer counters agree agrees with the point that the level of salinity should be reduced , reducing salinity is important, but she counters these solutions the lecturer states in the reading. disagrees with the proposed solutions).

Firstly , Firstly, the reading passage makes clear that the suggests that salt can be removed by some using special desalination facilities which could heats the water of heat the lake so that the water, leaving salt would be left behind.The lecturer , however , behind. However, the lecturer contends that this approach has significant drawbacks (the lecturer believes that there are flaws in the author's solution. he this solution). She points out that even though although these facilities could reduce the salt level of these lakes , it can levels in the lake, they may not restore its overall health (the facilities cannot bring these lakes back to health , for the reason that when these health). This is because during desalination, solid materials containing toxic chemicals are left behind (the facilities work , they will leave some solid material which might make the lake toxic material), posing a danger to both humans and the chemical compound left behind can be very dangerous. so wildlife. Thus, instead of benefiting the lake's health, this solution may have negative consequences (the facilities actually have negative instead of positive affect to the health of these lakes. effects on these lakes' health).

Secondly , Secondly, according to the passage ,the lecturer claims that people can use passage, diluting the lake's salinity with ocean water from the ocean to dilute the salt level of these lakes. is another viable solution. The lecturer , on the other hand , disputes this claim by arguing that implementing such a solution would be prohibitively expensive for local government resources (the lecturer rebuts this claim and argues that this solution can so it would be very expensive that the government can not afford this .He goes to say that expensive). She explains that since the nearest Ocean ocean shoreline is approximately 100 kilometers away from the lake (the nearest ocean is about 100 km away from these lakes away), which makes constructing pipelines or canals over such long distances would be financially unfeasible (this solution impossible. is impossible).

Thirdly, the reading passage says that people can build Lastly, building walls to divide up these lakes , what can controll the salinity sections of the Salton Sea is proposed in order to control salinity levels within its main section of the lake.Casting section. The lecturer casts doubt on that claim , this solution's long-term effectiveness by highlighting potential issues with geological activity in the region (the lecturer argues that this solution can not cannot work for a long time . she finds the weakness of this solution that some intense activity like earthquake time). She explains that earthquakes are common occurrences in this area and could easily destroy these walls causing them to collapse (earthquakes can destroys these walls and make them collapse destroy these walls), which means allowing high-salinity water from separated sections to mix back into low-salinity water from the main section (they can just work for a while.while).

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