Section Title: 6.文章修订

The reading passage and the lecture both discuss the topic of whether dinosaurs were endothermic or not. The passage argues that despite being classified as reptiles, there is considerable evidence to suggest that dinosaurs were endotherms. However, the lecture casts doubt on each point made in the reading passage, with the professor maintaining that dinosaurs could not maintain constant body temperatures in cold climates.

Firstly, the reading passage posits that the discovery of polar dinosaur fossils indicates their ability to survive in cold environments. In contrast, the lecturer contends that polar regions were much warmer during the time of dinosaurs and suggests that they might have migrated from warmer areas. Consequently, she believes that this argument is unconvincing.

Furthermore, the author asserts that having legs positioned under their bodies is a characteristic of endothermy in dinosaurs. The professor disputes this claim by stating that this feature merely supports a larger body size and does not necessarily indicate endothermy.

Lastly, while the reading passage claims that Haversian canals are indicative of an endothermic bone structure, the professor disagrees.

3.Task completeness The essay addresses the main points of the lecture, but some details are missing or unclear. To improve task fulfillment, ensure that you accurately summarize all the points made in the lecture and clearly explain how they cast doubt on specific points made in the reading passage. Additionally, avoid making assumptions or adding your own opinions.

Example 1: Original sentence: "Nevertheless, the lecture refuses this argument by stating that those fossils are warmth than today, therefore, dinosaurs going to polar regions probably for another reasons like they just migrate to there for hibernation." Improved sentence: "The lecturer counters this argument by explaining that during the time of dinosaurs, polar regions were warmer than they are today, allowing non-endothermic animals to survive. Furthermore, she suggests that dinosaurs could have migrated to warmer areas or hibernated during colder months."

Example 2: Original sentence: "However, this reasoning also refused by the lecture, which claims that even though dinosaur's bones have Haversian canals but they also have another material that can help them to grow quickly." Improved sentence: "However, the lecturer disputes this claim by pointing out that while dinosaur bones do contain Haversian canals, they also exhibit growth rings. These growth rings indicate periods of slow or no growth during cooler periods and are characteristic of non-endothermic animals."

4.Essay structure and organization The essay has a basic structure with an introduction, body paragraphs addressing each point from the lecture and reading passage, and a conclusion. However, it lacks clear transitions between ideas and paragraphs. To improve organization and coherence in your essay:

• Begin each paragraph with a clear topic sentence.

• Use appropriate transition words and phrases to connect ideas.

• Ensure that each paragraph focuses on a specific point from the lecture and reading passage.

Example 1: Original sentence: "Firstly, the reading claims that dinosaurs are endotherm since their fossils have been found in polar regions where animals have to maintain a stable temperature to survive." Improved sentence: "Firstly, the reading claims that dinosaurs were endothermic because their fossils have been found in polar regions, where only animals capable of maintaining a stable body temperature could survive. However, the lecturer disputes this claim by explaining..."

Example 2: Original sentence: "Secondly, the reading suggests that the structure of the dinosaur that its legs are underneath their body, which as same as modern endotherms." Improved sentence: "Secondly, the reading suggests that dinosaurs' leg structure, with legs positioned underneath their bodies like modern endotherms, is evidence of their endothermic nature. In contrast, the lecturer argues..."

5. Grammar

The reading passage presents three evidences to support the opinion that dinosaurs isare(Detects potentially wrong usage of "is") belongbelonged(Agreement: 'been' or 'was' + past tense) to endotherms. However, the lecture counts all these viewpoints, stating that are unconvincing. Firstly, the reading claims that dinosaurs are endotherm since their fossils have been found in polar regions where animals have to maintain a stable temperature to survive. Nevertheless, the lecture refuses this argument by stating that those fossils are warmth than today, therefore, dinosaurs going to polar regions probably for another reasons like they just migrate to theretheir(Detects potentially wrong usage of "there" instead of "their") for hibernation. Secondly, the reading suggests that the structure of the dinosaur that its legs are underneath their body, which as same as modern endotherms. However, the lecture disputes this theory and claims that dinosaurs' daily activities require a higher energy, they need legs underneath their bodies to support more weight due to they have big size. Finally, the reading assumes that dinosaur's bones include high dense structures called Haversian canalscanals,(This rule identifies whether commas are missing in a sentence.) which is a strong indicator that they are endotherms. However, this reasoning also refused by the lecture, which claims that even though dinosaur's bones have Haversian canals but, but(comma between independent clauses) they also have another material that can help them to grow quickly. These body material can help them have a better adaptation in a cool environment. For all these reasons, dinosaurs are not endotherms.

Section Title: 6. Revised Essay

The reading passage presents three pieces of evidence supporting the idea that dinosaurs were endotherms. However, the lecture counters each of these points, arguing that they are unconvincing.

Firstly, the reading claims that dinosaur fossils found in polar regions suggest they were endotherms since only animals capable of maintaining a stable internal temperature could survive in such cold climates. The lecture refutes this argument by stating that during the time when dinosaurs lived, polar regions were warmer than they are today. Consequently, it is possible that dinosaurs migrated to these areas for reasons such as hibernation rather than being endothermic.

Secondly, the reading highlights the similarity between dinosaurs and modern endotherms in terms of leg position and movement, with both having legs positioned underneath their bodies. The lecture disputes this theory by asserting that dinosaurs required a high-energy body structure to support their large size rather than being built for running like endotherms. Thus, having legs under their bodies allowed them to carry more weight and grow larger.

Lastly, the reading posits that the presence of Haversian canals in dinosaur bones is a strong indicator of endothermy since these structures are characteristic of rapid growth associated with endothermic animals. The lecture challenges this reasoning by pointing out that while dinosaur bones do contain Haversian canals, they also exhibit growth rings indicative of periodic growth patterns. This pattern of rapid growth followed by slow or no growth is characteristic of non-endothermic animals that do not maintain a constant body temperature year-round.

Taking these counterarguments into account, it becomes evident that the claim for dinosaurs being endotherms is not as convincing as initially presented in the reading passage. (281 words)

According to the material offered above the writer and the speaker show different attitudes towards whether dinosaurs are endotherms. In the article, the writer mainly lists three reasons to demonstrate that dinosaurs are endotherms. However, the narrator strongly refutes his opinion by giving further explanation.

At first, the writer holds the view that dinosaur fossils have been discovered in polar regions. To be more specific ,, (Use of whitespace before comma and before/after parentheses)only endotherms that can maintain a temperature could live in polar regions. On the contrary, the professor contends that the polar regions were much warmer than today. The dinosaur would migrant to the warmer area. So living in the warm region prove the dinosaur are not endotherms.

Secondly, it is mentioned in the article that the legs of dinosaurs are under the body. In other words, the legs of all modern endotherms are underneath the body. Instead, the speaker disagreedisagrees(punctuation + singular noun + plural verb) with this statement. He says that this structure of dinosaur can support them have more weight. If the dinosaursdinosaur's(This rule identifies whether there is a missing apostrophe before an 's'.) leg under the body, they can grow to large size.

Thirdly, the writer supports that dinosaur fossils usually have Haversian canals, which is to say, the endotherms include structures called Haversian canals. Instead, the lecture points out its weakness. He explains that dinosaur havedinosaur has(Plural verb after 'this' or 'that') the growth ring which show their growth start or grow slowly. That is the evidence dinosaurs are not endotherms.

Section Title: 6.文章修订

The passage and the lecture present conflicting views on whether dinosaurs were endotherms. The author provides three main arguments to support the idea that dinosaurs were endotherms, while the speaker refutes each of these points with alternative explanations.

Initially, the author argues that the discovery of dinosaur fossils in polar regions indicates that they were endotherms, as only animals capable of maintaining a constant body temperature could survive in such cold climates. However, the lecturer disputes this claim by stating that polar regions were considerably warmer during the time when dinosaurs lived. Furthermore, she suggests that these so-called polar dinosaurs could have migrated to warmer areas or hibernated during colder months, much like modern reptiles do. Thus, their presence in polar regions does not necessarily prove they were endotherms.

The second point made by the author is that the leg position and movement of dinosaurs resemble those of modern endotherms, with legs positioned underneath their bodies rather than at their sides like crocodiles and many lizards. The lecturer challenges this argument by explaining that having legs under their bodies allowed dinosaurs to support more weight and grow to larger sizes, which offered them certain advantages. Consequently, this leg structure does not necessarily imply that they were high-energy endotherms built for running.

Lastly, the author cites the presence of Haversian canals in dinosaur bones as evidence for their endothermic nature since these structures are typically found in endotherm bones and allow for rapid growth. In contrast, the speaker highlights that dinosaur bones also exhibit growth rings – thickened areas indicating periods of slow or no growth during cooler times. This pattern of periodic growth is characteristic of non-endothermic animals rather than true endotherms which maintain constant body temperatures year-round and continue growing rapidly even in cooler environments.

In summary, while the author presents several arguments supporting the idea that dinosaurs were endotherms, the lecturer effectively counters each point with alternative explanations, casting doubt on the passage's claims. (329 words)
