Conservation-reliant species means a type of species which depends on human's conservation efforts for survival. Conservation-reliant species refer to those that depend on human conservation efforts for their survival. (修改了句子结构，使其更自然) And in the professor's example, he says that there are a lot of bird species that are struggle for survival and close to extinct, and they need to eat mass amount of vegetation for survival. In the professor's example, he mentions numerous bird species struggling to survive and being on the verge of extinction, requiring a large amount of vegetation for sustenance. (修改了句子结构，词汇和语法，使其更自然) Therefore, conservationists keep wilds out from the forests and build fences around the forests and keep repairing them, which undoubtedly is quite expensive. As a result, conservationists exclude wild animals from the forests by building and maintaining fences around them, which is undoubtedly costly. (修改了句子结构，词汇和语法，使其更自然) However, if the conservationists stop the program, it's really difficult for these bird species to survive without human's effort. Nonetheless, if conservationists cease their efforts, it would be extremely challenging for these bird species to survive without human intervention. (修改了句子结构，词汇和语法，使其更自然)

Revised Answer (140 words):

Conservation-reliant species refer to those that depend on human conservation efforts for their survival. In the professor's example, he mentions numerous bird species struggling to survive and being on the verge of extinction in Hawaii's forests, requiring a large amount of vegetation for sustenance. The introduction of domesticated pigs and goats, which escaped into the forests and destroyed the birds' habitat by consuming massive amounts of vegetation, exacerbated the situation. As a result, conservationists exclude wild animals from the forests by building and maintaining fences around them, which is undoubtedly costly. These efforts have proven effective in some areas, but they require continuous financial support. Nonetheless, if conservationists cease their efforts, it would be extremely challenging for these bird species to survive without human intervention.

Original: Conservation-reliant species refers to animals whose survival depends on human conservation efforts to their habitats. Conservation-reliant species are animals that depend on human conservation efforts for their survival in specific habitats. (保护依赖物种是指依赖人类保护努力在特定生境中生存的动物。)

Discontinuation of these efforts can lead to extinction of these animals. If these efforts are discontinued, it may result in the extinction of these animals. (如果停止这些努力，可能导致这些动物的灭绝。)

The professor gives an example of bird species struggling for survival in the forest in Hawaii. The professor cites an example of bird species struggling to survive in Hawaiian forests. (教授举了夏威夷森林中鸟类努力生存的例子。)

Due to the introduction of domestic pigs and goats into Hawaii and their escaping into the forest, the vegetation environment of the birds living in has been destroyed significantly. Owing to the introduction of domestic pigs and goats in Hawaii and their subsequent escape into the forests, the birds' habitat has been significantly damaged. (由于家猪和家山羊被引入夏威夷并逃入森林，鸟类的栖息地受到了严重破坏。)

Therefore, people started their conservation of the bird species by setting specific areas and keep the pigs and goats out. As a result, people initiated conservation efforts for these bird species by designating protected areas and excluding pigs and goats. (因此，人们通过划定保护区并排除猪和山羊来保护这些鸟类。)

This strategy is very effective but also expensive due to the high cost of establishing equipments and repairs. This strategy is highly effective but also costly, as it requires significant investment in equipment installation and maintenance. (这种策略非常有效，但由于设备安装和维护成本高昂，也很昂贵。)

However, if these efforts were stopped, then the birds can become extinct. Nonetheless, if these efforts were to cease, the birds could face extinction. (然而，如果这些努力停止，鸟类可能面临灭绝。)

5.语言使用

Original Answer: The reading is about conversation-related species. The reading discusses conservation-reliant species. (将“conversation”改为“conservation”，因为这是正确的词汇。) It states that human beings will help some specific species to recover their habitats to make sure they can survive there. The professor used specific examples. In Hawaii, there were birds living in a forest. However, when pigs and goats moved there and became domestic there, the forest was damaged drastically. So those birds lost their families. To help those birds living there, humans just built some fences to prevent those pigs and goats out of the habitats of birds. To assist the birds, humans constructed fences to keep the pigs and goats away from the birds' habitats. (改进了句子结构，使其更自然。) However, the issue is this program is very expensive because people have to build the fence and also keep the fence. So it's hard to see that it's good or not.

Revised Answer (140 words):

The reading discusses conservation-reliant species, which are dependent on human efforts for their survival. The professor provides a specific example of bird species in Hawaii's forests that are struggling due to habitat destruction caused by invasive pigs and goats. To assist these birds, humans have constructed fences to keep the pigs and goats away from the birds' habitats, allowing them to recover. However, this conservation program faces challenges due to its high cost, as building and maintaining the fences require significant financial resources. As a result, it is difficult to determine whether this approach is truly effective or sustainable in the long run. Overall, the professor's example illustrates the concept of conservation-reliant species and the challenges associated with implementing and maintaining such conservation efforts.

4.话题发展 The response provides a coherent and well-organized explanation of the concept of conservation-reliant species, using the example from the lecture. However, it could be improved by providing more specific details from the listening passage, such as mentioning the impact of domesticated pigs and goats on the bird species in Hawaii. Additionally, the response could benefit from clearer transitions between ideas and more varied sentence structures to enhance overall clarity and coherence.

5.语言使用

Original Answer: The professor notes that in Hawaii, America, some birds are struggling to survive near extinction because some animals like goats and pigs, they eat a lot of vegetations and destroy the forests. The professor mentions that in Hawaii, the United States, certain bird species are facing the threat of extinction due to animals such as goats and pigs that consume large amounts of vegetation and devastate the forests. (将句子结构进行了调整，使其更自然流畅。同时，用词更准确和丰富。)

So conservationists build fences around the forest as a habitat to prevent pigs and goats. Therefore, conservationists construct fences around the forests to protect the birds' habitat from pigs and goats. (改进了句子结构和语法，使表达更清晰。)

The program is really effective for protecting the birds in the forests, but it spends a lot of money repairing the program, and if this stops, the birds are difficult to survive. The program proves to be effective in safeguarding the birds within the forests; however, it requires significant financial resources for maintenance. If these efforts cease, the survival of these bird species would be jeopardized. (优化了句子结构，增加了过渡词，使表达更自然。)

Revised Answer (140 words):

The professor mentions that in Hawaii, the United States, certain bird species are facing the threat of extinction due to animals such as goats and pigs that consume large amounts of vegetation and devastate the forests. These invasive animals were introduced to the region and have since caused significant damage to the birds' natural habitat. Therefore, conservationists construct fences around the forests to protect the birds' habitat from pigs and goats. This conservation effort aims to recreate and maintain the original habitat conditions for these bird species, making them conservation-reliant. The program proves to be effective in safeguarding the birds within the forests; however, it requires significant financial resources for maintenance. If these efforts cease, the survival of these bird species would be jeopardized, illustrating the concept of conservation-reliant species as discussed in the lecture.
