5. Grammar

The lecturer opposes the reading material's assertion that dinosaurs are endotherms by presenting research results and explanations, arguing the points given in the reading are not convincing enough to support the assertion. In the first place, the reading material posits that dinosaur fossils have been discovered in polar areas, indicating that dinosaurs are endotherms capable of living in cold environments. However, the lecturer points out that during ancient periods before the extinction of dinosaurs, the polar areas were much warmer than modern climate. In fact, climates might be warm enough for animals that are not endotherms to live. Additionally, even though dinosaur fossils were found, that doesn't necessarily mean they live in polar area all the time. They may migrate to warmer environments during specific seasons like current animals do. Secondly, as for the leg position and movement suggested in the reading material, the lecturer disputes the claim that having legs positioned underneath the body means rapid movement and being endotherms, and puts forward another reasonable explanation. The lecturer reckons that this leg position may have close connection to supporting more body mass. As a matter of fact, larger body size and mass entail a great many advantages for the dinosaurs, which proves the correctness of this perspective further. Last but not the least, the reading material suggests the existence of haversian canals in the dinosaurs' bodies shows a connection between endothermyendotherm(misspelling) and bone structure. But the lecturer challenges this assertion with research results. Although it's true that many dinosaurs had haversian canals in their body, research shows that there exists growth rings in the dinosaur fossils, which means alternating periods of slow or even no growth and rapid growth. This provides strong evidence that dinosaurs are not endotherms because the steady body temperature of endotherms enables them to grow rapidly all the time even during cold weathers. To summarize, the lecturer objects the reading material's claims with detailed explanations and solid research results, strongly contending that dinosaurs are not endotherms.

6. Revised Essay

The lecturer challenges the reading material's assertion that dinosaurs were endotherms by presenting research results and alternative explanations, arguing that the points given in the reading are not convincing enough to support this claim.

Firstly, the reading material posits that dinosaur fossils discovered in polar regions indicate that dinosaurs were endotherms capable of living in cold environments. However, the lecturer points out that during the prehistoric era when dinosaurs existed, polar regions were much warmer than they are today, potentially warm enough for non-endothermic animals to survive. Moreover, even though dinosaur fossils were found in these areas, it does not necessarily mean they inhabited these regions year-round. They may have migrated to warmer climates during specific seasons or hibernated like many modern reptiles do.

Secondly, regarding leg position and movement suggested in the reading material, the lecturer disputes the claim that having legs positioned underneath the body implies rapid movement and endothermy. Instead, they propose another plausible explanation: this leg position may be closely related to supporting increased body mass. In fact, a larger body size and mass would confer numerous advantages for dinosaurs, further substantiating this perspective.

Lastly, while the reading material suggests a connection between endothermy and bone structure due to the presence of Haversian canals in dinosaur bones, the lecturer challenges this assertion with additional research findings. Although it is true that many dinosaur bones contained Haversian canals, studies have also revealed growth rings within these fossils. These growth rings indicate alternating periods of slow or no growth and rapid growth—a pattern characteristic of non-endothermic animals. This provides strong evidence against dinosaurs being endotherms because true endotherms maintain a constant body temperature year-round, enabling them to grow rapidly even during cooler periods.

In summary, the lecturer counters the reading material's claims with detailed explanations and robust research results, strongly contending that dinosaurs were not endotherms. (311 words)

Firstly, the listening say when dinosaurs was there, the cold places was not so cold. So, maybe dinosaurs not need to be warm-blooded to live there. They could move to hot places or sleep like snakes in winter. This mean finding them in cold place not prove they warm-blooded.

Second, about legs under body, listening say it's not for running fast but for holding more weight. Dinosaurs waswere(Detects potentially wrong usage of "was") very big, so they need strong legs under them to hold up. It not mean they have to be warm-blooded.

Yes, dinosaurs bones have canals, but they also have rings that show they grow slow or stop in cold times. This is like cold-blooded animals, not like warm-bloodedblooded,(This rule identifies whether commas are missing in a sentence.) who grow same speed all time. So, this also not a sure thing for warm-blooded.

Section Title: 6.文章修订

The reading passage presents arguments supporting the idea that dinosaurs were endothermic, or warm-blooded, like modern birds and mammals. It cites evidence such as their presence in polar regions, leg position and movement, and the presence of Haversian canals in their bones. However, the lecture casts doubt on these claims by providing alternative explanations for each piece of evidence.

Firstly, the lecture contends that during the time when dinosaurs existed, polar regions were much warmer than they are today. This would have allowed even non-endothermic animals to survive in those areas. Furthermore, it suggests that during colder months, so-called polar dinosaurs could have migrated to warmer regions or hibernated like many modern reptiles do. This undermines the argument that their presence in cold climates is definitive proof of endothermy.

Secondly, regarding leg position and movement, the lecture argues that having legs underneath their bodies does not necessarily indicate that dinosaurs were high-energy endotherms built for running. Instead, this body structure could have evolved to support more weight, allowing dinosaurs to grow larger—a trait which would have provided them with significant advantages. Consequently, endothermy is not required to explain why dinosaurs had legs positioned under their bodies.

Lastly, while it is true that many dinosaur bones contain Haversian canals—an indicator of endothermy—the lecture points out that these bones also exhibit growth rings. These rings represent periods when dinosaurs experienced slower growth or stopped growing altogether during cooler times. This pattern of periodic growth is characteristic of non-endothermic animals rather than true endotherms who maintain constant body temperature year-round and continue growing rapidly even in cooler environments.

In conclusion, the lecture challenges the reading passage's assertions by offering alternative explanations for each piece of evidence presented. As a result, it remains uncertain whether dinosaurs were indeed warm-blooded or not. (300 words)

3.Task completeness The essay does a good job of 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 providing more detailed explanations and elaborating on the contrasting perspectives between the reading and listening passages.

Suggestions for improvement:

• Expand on the reasons why each argument from the reading passage is not convincing, based on the information provided in the lecture.

• Provide more specific examples or evidence from both passages to support your explanations.

Examples:

1. Instead of just mentioning that "large size could bring myriads of benefits to dinosaurs," explain what those benefits are and how they relate to endothermy.

2. When discussing growth rings, provide more context about how they indicate periods of rapid growth followed by slow or no growth, and explain why this pattern is not consistent with endothermy.

4.Essay structure and organization The essay has a clear structure with an introduction, body paragraphs addressing each point, and a conclusion. The organization is logical, with each paragraph focusing on a specific point from the reading passage and its corresponding counterpoint from the lecture. However, there is room for improvement in making transitions between ideas smoother and ensuring that each paragraph has a clear topic sentence.

Suggestions for improvement:

• Use transition words or phrases to guide readers through your arguments more smoothly.

• Ensure that each paragraph begins with a clear topic sentence that outlines what will be discussed in that paragraph.

Examples:

1. Use phrases like "Furthermore" or "In addition" when introducing new points or arguments to help guide readers through your essay.

2. Instead of starting a paragraph with "Firstly," begin with a more specific topic sentence, such as "The first argument presented in the reading passage is that the discovery of dinosaur fossils in polar regions suggests they were endotherms."

Contrarily, the lecturer contends that the climate of Polar RegionRegions that dinosaurs lived was much warmer than todaytoday, which were habitable for non-endotherms to live. In addition,Additionally, when the temperature went down, the dinosaurs could migrate to warmer areas or hibernate to keep body heat. Therefore, the fossils found in Polar Region doesRegions do not prove that dinosaurs are endotherms. Secondly, the author suggests that the legs of all modern endotherms are underneath the body, and so were the legs of dinosaurs. This strongly suggests that dinosaurs were endotherms. The lecturer disputes this point by highlighting that the leg position was not only built for running but more importantly, legs were built to support more weight, inweight. In other words, dinosaurs were thus able to grow larger. It is clearlyclear that large size could bring myriads of benefits to dinosaursdinosaurs, thus there is no need to improve the speed of running.

6. Revised Essay

The author in the reading passage presents three pieces of evidence to support the view that dinosaurs were endotherms. However, the lecturer in the listening part offers a contrasting perspective on this issue, casting doubt on each point made by the author.

Firstly, the author claims that dinosaur fossils discovered in polar regions indicate that these creatures could maintain a temperature well above that of their surroundings, which is a characteristic of endotherms. In contrast, the lecturer contends that during the time when dinosaurs lived, polar regions were much warmer than they are today and were habitable for non-endothermic animals. Moreover, when temperatures dropped, dinosaurs could have migrated to warmer areas or hibernated to conserve body heat. Consequently, the presence of fossils in polar regions does not definitively prove that dinosaurs were endotherms.

Secondly, the author suggests that since both modern endotherms and dinosaurs have legs positioned underneath their bodies, this strongly implies that dinosaurs were also endothermic. The lecturer disputes this point by emphasizing that leg position served not only for efficient running but more importantly for supporting greater weight. This allowed dinosaurs to grow larger and gain numerous advantages from their size; thus, there is no need to assume enhanced running speed as an indicator of endothermy.

Lastly, the author asserts that Haversian canals present in dinosaur bones are a strong indicator of endothermy because these structures enable rapid growth—a characteristic feature of endothermic animals. The lecturer challenges this notion by stating that growth rings found in dinosaur bones reveal alternating periods of rapid growth followed by slower or even no growth when environmental conditions became cooler. In contrast, true endotherms can maintain rapid growth even under cool conditions. (284 words)
