3.Task completeness The essay does a good job of addressing the specific requirements of the task by summarizing the points made in the lecture and explaining how they cast doubt on specific points made in the reading passage. However, there is room for improvement in terms of language use and clarity.

Suggestions for improvement:

• Avoid repetition of phrases or words, such as "the reading material" or "the speaker."

• Use more precise vocabulary to convey your ideas more effectively.

Examples:

1. Instead of writing "the reading materials believe," you could write "the reading passage argues."

2. Instead of writing "hardly find any dead sea otters," you could write "few dead sea otters have been found."

4.Essay structure and organization The essay has a clear structure with an introduction, body, and conclusion. Each paragraph focuses on a specific point from the lecture and provides supporting details. However, transitions between ideas and paragraphs could be improved for better coherence.

Suggestions for improvement:

• Use clear transition words or phrases to connect ideas within paragraphs.

• Make sure each paragraph has a clear topic sentence that introduces the main point being discussed.

Examples:

1. To improve transitions within paragraphs, you could use phrases like "on the other hand" or "in contrast" to show a shift in perspective.

2. For clearer topic sentences, instead of writing "Firstly, the reading material claims," you could write "The first argument presented in the reading passage is that pollution is causing sea otter decline due to known sources along the Alaskan coast."

5. Grammar

The reading and listening passages debate the reason for the decline of sea otter population. The reading materials believe that environmental pollution is the main reason for the declinedecline,(This rule identifies whether commas are missing in a sentence.) providing three reasons, which are contradicted by the following lecture.

Firstly, the reading material claims that there exist some known sources of pollutionpollution,(This rule identifies whether commas are missing in a sentence.) such as oil rigs and other industrial chemical pollution. It is the increased levels of chemical that can decrease the otters' resistance to life-threatening infectionsinfections,(This rule identifies whether commas are missing in a sentence.) which will finally result in their deaths. However, the speaker contradicts the reading's claim by pointing out they are hardly findfound(Agreement: 'been' or 'was' + past tense) any dead sea otters along Alaska beaches. The reason is that predator can eat otters immediately, thus it cannot wash off up on shore.

Secondly, the reading material argues that environmental pollution affects the entire ecosystem rather than a single species. The reasons are twofold. For one thingthing,(This rule identifies whether commas are missing in a sentence.) other sea mammals such as seals and sea lions are also declining. For otherthe other(This rule identifies whether the article 'the' is missing in a sentence.) thing, widely occurring predators, such as orcas, can result in the same consequence. But orcas prefer to eat larger prey like whales. However, the speaker holds the opposite opinion. He believes orcas, under the huge survival pressure, will start hunting smaller sea mammals since wheals are killed by human hunters so that orcas have to change their diet to survive.

Thirdly, the reading material points out that the pollution theory can explain that the ocean environmental factors may cause uneven concentrations of pollutants along the coast. However, according to the speaker, the reading' sreading's(space after apostrophe in contraction (e.g. I' m)) claim does not hold water. He argues that orca predation theory can explain the uneven pattern of otter decline because at some placesplaces'(Possessive apostrophe error) predation can access to theto(Detects potentially wrong usage of "to the") where sea otters live, therefore the number of sea otters will decline greatly. When orcas can't access shallow or rocky locations, sea otter population will keep stable.

Section Title: 6. Revised Essay

The reading and listening passages discuss the reasons behind the decline of the sea otter population. The reading passage posits that environmental pollution is the primary cause, providing three supporting arguments. However, the lecture casts doubt on these points by presenting contradictory evidence.

Firstly, the reading passage asserts that known sources of pollution, such as oil rigs and industrial chemical pollution, contribute to increased levels of chemicals that can weaken otters' resistance to life-threatening infections, ultimately causing their deaths. In contrast, the lecturer argues that this claim is undermined by the scarcity of dead sea otters found on Alaskan beaches. This observation supports the predator hypothesis since predators would consume otters immediately, preventing them from washing ashore.

Secondly, the reading passage contends that environmental pollution affects not only sea otters but also other sea mammals such as seals and sea lions. It suggests that widespread predators like orcas could have a similar impact; however, orcas typically prefer larger prey like whales. The lecturer disputes this argument by stating that orcas have likely adapted their diet to include smaller sea mammals due to a scarcity of whales caused by human hunting activities.

Lastly, the reading passage proposes that ocean currents and other environmental factors may create uneven concentrations of pollutants along the coast, explaining the irregular pattern of otter decline. However, the lecturer counters this claim by asserting that orca predation offers a more plausible explanation for this phenomenon. According to him, locations easily accessible to orcas experience significant declines in sea otter populations while those in shallow or rocky areas inaccessible to orcas maintain stable populations.

20. 3.Task completeness

The essay does address the specific requirements of the task by summarizing the points made in the lecture and explaining how they cast doubt on specific points made in the reading passage. However, there is room for improvement in terms of clarity and accuracy. The essay should more clearly explain how each point from the lecture contradicts or weakens a point from the reading passage.

Suggestions for improvement:

• Clearly state each point from the lecture and directly relate it to a specific point from the reading passage.

• Use more precise language to explain how each point from the lecture casts doubt on a point from the reading passage.

Examples:

1. Instead of saying "the professor retorts that people never find the dead seals," you could write, "the professor argues that no dead sea otters have been found washed up on Alaskan beaches, which would be expected if pollution were causing their deaths."

2. Instead of saying "hunting will change the survival mode of these mammals," you could write, "the professor explains that orcas have likely started hunting smaller sea mammals like seals, sea lions, and sea otters due to a decline in their preferred prey, whales."

4.Essay structure and organization The essay has a basic structure with an introduction, body paragraphs addressing each point, and a conclusion. However, there is room for improvement in terms of organization and transitions between ideas.

Suggestions for improvement:

• Use clear topic sentences at the beginning of each body paragraph to introduce each main point.

• Improve transitions between ideas and paragraphs to create better coherence.

Examples:

1. For your second body paragraph's topic sentence, instead of writing "Second, the author claims that most of the seal and seal lion are decline, or endangered," you could write, "The second point made in the lecture is that the decline of other sea mammals can be attributed to orca predation rather than pollution."

2. To improve transitions between ideas, instead of writing "While the professor asserts that the reason of the decline is not because of the pollution, is the human's hunting," you could write, "The professor counters this argument by explaining that human hunting has led to a decrease in whale populations, forcing orcas to change their diet and prey on smaller sea mammals."

5. Grammar

The reading passage and listening discuss about whatdiscuss what(Collocation: consider (about)) cause the decline of the sea otter, and then experts put forward 2 theories, whether the pollution or predator theory. According to the reading, the author asserts that the pollution hypothesis seemed better. However, the professor of the listening refutes that and stand on the predator theory.

First of allFirst(first of all (first)), the writer points out that there were known sources of the pollution, such as oil rigs and chemical pollution. This pollution will destroy the resistance of otters, even cause their death. On the contrary, the professor retorts that people never find the dead seals, which is unexpected. Therefore, pollution is not the most reason. The seal is consistent to predator hypothesis.

Second, the author claims that most of the seal and seal lion are declinein decline(This rule identifies whether the preposition 'in' is missing in a sentence.), or endangered. The pollution already affects the entire ecosystem. While the professor asserts that the reason of the decline is not because of the pollution, is the human's hunting. Hunting will change the survival mode of these mammals, consequently, others seal and sea lion, even otter will be affected by hunting.

At last, the reading passage indicateindicates(punctuation + singular noun + plural verb) that the Alaskan location occur the uneven pattern of otter decline. Because the otter of Alaskan decline quickly but others' region is stable. Instead, the professor explains that the phenomenon indicate that the reason is predators rather than pollution. As a result of the Alaskan is large, and pollution cannot access to the shallow and rockets, but these areas of populations are not decline. Therefore, the predator theory is more convinced than the pollution theory.

Section Title: 6. Revised Essay

The reading passage and listening discuss the cause of the sea otter's decline, presenting two theories: pollution and predation. While the reading passage supports the pollution hypothesis, the lecture casts doubt on this theory and favors predation as the primary cause.

Firstly, the author of the reading passage highlights known sources of pollution, such as oil rigs and chemical pollution, which could weaken otters' resistance to infections and ultimately lead to their death. However, the professor counters this argument by pointing out that no dead sea otters have been found washed up on Alaskan beaches, which would be expected if pollution were causing their demise. Instead, this absence of dead otters supports the predator hypothesis.

Secondly, the reading passage claims that declines in other sea mammals like seals and sea lions indicate that pollution is affecting the entire ecosystem. In contrast, the professor argues that human hunting has led to a scarcity of whales in the area, forcing orcas to change their diet and prey on smaller sea mammals such as seals, sea lions, and otters. This shift in predation patterns is likely responsible for declines in these species rather than pollution.

Lastly, while the reading passage suggests that an uneven pattern of otter decline across Alaskan locations points to pollution as a cause, with some populations declining rapidly while others remain stable; the professor offers an alternative explanation. According to her argument, accessibility for orcas determines whether or not otter populations decline. In areas easily accessible to orcas, otter numbers have dropped significantly; however, shallow and rocky locations where orcas cannot reach have seen stable otter populations. This evidence lends greater credibility to the predator theory over pollution as a primary cause for declining sea otter populations. (293 words)

5. 语法批改

The lecture supports the predation theory, while casting doubts on the pollution hypothesis asserted in the reading passage. Firstly, the lecture notes that environmental pollution will lead to lethal infections, and yet dead sea otters can't actually be found on the Alaskan shores. This fact challenges the passage's statement that pollution is the most likely cause of the otters' decline. Secondly, according to the lecture, whales are basically extinct in that certain region due to human hunters. Thus, although the orcas may have a favor to whales, they had to change their diet under current circumstances and hunt smaller sea mammals instead. Therefore, the decrease of sea lions, seals and otters can be explained by the predation hypothesis, which contradicts the passage's claim that environmental pollution is the reason of the decline of various species. Lastly, the lecture contends that the vital factor that decides the pattern of the otters' decline is whether or notwhether(the question whether (whether) etc.) their dwelling locations are accessible to orcas. Specifically speaking, in areas that can be easily accessed by orcas, the number of otters dropped significantly. In the opposite situation, it remained stable. This argument refutes the passage's opinion that the pollution hypothesis is the best explanation to the uneven pattern of the otters' decline.

First, the lecture highlights that despite pollution causing lethal infections, dead sea otters are not found washed up on Alaskan shores. This fact contradicts the reading passage's assertion that pollution is the primary cause of otter decline. Second, the lecture explains that due to human hunting, whales have become scarce in the region, forcing orcas to change their diet and hunt smaller sea mammals. Consequently, the decline of sea lions, seals, and otters can be attributed to predation rather than environmental pollution as suggested in the reading passage.
