Aperçu de la Tâche

Texte de Lecture

Exaptation The physical features of an animal's body usually serve a specific purpose-they function to increase the animal's chances of survival. But over time in response to a particular challenge in its environment an animal species will sometimes use one of its existing features for a new purpose. This is known as exaptation. By finding another use for one of its physical features exaptation allows animals to respond to additional challenges in their environment. The animal may continue to use the physical feature for its older purpose while also using it for the new purpose.

Question

23. 3.Delivery

The speaker's delivery is generally clear and fluid, with a consistent pace and only occasional pauses. However, there are some pronunciation issues that need to be addressed, such as "exception" instead of "exaptation" and "Aran" instead of "heron." To improve, the speaker should practice pronouncing these words correctly and work on enunciating more clearly.

4.Topic Development The response is coherent and well-organized, with clear connections between ideas and sufficient support or examples from both the reading passage and the lecture. The speaker successfully explains how the heron's use of its wings to block sunlight illustrates exaptation. However, there is room for improvement in providing more accurate details from the lecture, such as specifying that the heron lives near rivers and marshes in Africa. Additionally, the speaker could work on using more varied vocabulary to avoid repetition and enhance their explanation.

5.Language Use

The reading passage introduces a topic exception exaptation(corrected for accurate terminology) that describes an existing physical feature of an animal body to use for a new purpose and that is basically to increase their survival and they can use it for the older purpose as well as the newer purpose as well. And the professor dives deeper into the subject and where he mentioned about an example of a rung wading(corrected for accurate description) bird which is basically a bird to hunt fishes but because of the sunlight reflecting on the surface of the ocean it's become harder for the bird to catch the fishes but over time the Aran heron(corrected for accurate pronunciation) developed this feature of their wings they basically hide the sun because of their wings and then it just eliminates the glare from the sunshine and they can easily see the fishes.

Revised Answer (140 words):

The reading passage introduces exaptation, a concept describing how animals use an existing physical feature for a new purpose to increase their chances of survival. They can use this feature for both its original and new purposes. The professor elaborates on this concept by providing an example of a wading bird, specifically a heron, which hunts fish in rivers and marshes. Due to sunlight reflecting on the water's surface, it becomes difficult for the heron to spot fish. However, over time, the heron has adapted by using its wings to block sunlight, creating shade that eliminates glare from the water's surface. This allows the heron to see fish more easily, demonstrating exaptation as it continues to use its wings for both flying and shading purposes.

从表达方面来看,发言者的语言流利度和语速基本一致,仅有少量停顿。但在某些地方,发言者的停顿不太合适,导致了标点问题。此外,发言者在发音上也有一些不准确之处,导致了拼写错误。建议发言者在练习口语时注意提高发音准确度,并适当调整停顿,使语言更加流畅。

4.话题发展 从话题发展方面来看,发言者的回答内容基本上是连贯和有组织的,观点之间的联系也比较清晰,并给出了一定的支持或例子。但是,在描述鹭鸟如何利用翅膀遮阳的过程中,发言者使用了“halloweens”这个词汇,这是一个错误的词汇选择。建议发言者在练习时注意词汇的准确性,并尝试提供更多相关细节以支持观点。

5.语言使用

Original Answer: Acceptation is that an animal uses its existing features for new purposes. Take the halloweens herons (词汇错误,应为herons而非halloweens) as an example. Halloweens are fed on the fishes in shallow water, and it is hard for them to see fishes while the sun is gone. As a solution, they use wings not only to fly but also block the sun by putting them above their heads and use the wings as well as the body to create a shelter over the water so that they can see the fish on the surface of the water clearly and catch the fish to feed themselves. Thank you for watching!

Revised Answer (140 words): Exaptation refers to animals using their existing features for new purposes. Take herons as an example. Herons feed on fish in shallow waters, and it can be difficult for them to see fish when sunlight creates glare on the water's surface. To overcome this challenge, herons use their wings not only for flying but also for blocking sunlight by holding them above their heads. This creates a shaded area over the water, allowing herons to see fish more clearly and catch them more easily. In this way, herons have adapted their wings for a new purpose, demonstrating exaptation in action. Thank you for listening!

在修改后的回答中,我们纠正了词汇错误,将“halloweens”改为正确的“herons”。同时,我们对句子结构进行了调整,使其更加自然流畅。此外,我们还添加了一些高级词汇,如“glare”和“overcome”,以提高回答的质量。通过这些修改,我们希望能够帮助学生提高口语回答的语言使用水平,从而获得更高的分数。

Exemptation Exaptation(应为 Exaptation,而非 Exemptation) is a technique used by some animals that you they(用 they 替换 you,因为这里指的是动物) can use one of their existing physical features for another purpose to respond to the additional challenges when it's necessary. In the lecture, the professor used the type of hiron heron(应为 heron,而非 hiron) as an example. Such hiron heron will always walk in the shallow sea and will eat the fishes at their daytime. It is always hard to see those fishes because the sunlight will always glaring glare(应使用动词形式 glare,而非名词形式 glaring) and no reflection. So they find out a cool solution which is using their wings. At past, they will use their wings to fly as most of the birds. However, they will always use the wings as an umbrella to block the sunlight and create a shade to find the fish. More specifically, the hiron heron will use their wings to block the sunlight and will eliminate the sun so they can see the fish better in the sea.

However, it is difficult to see the fish due to sunlight glare and lack of reflection. The heron has found a solution by using its wings. In the past, the heron used its wings primarily for flying, like most birds. Now, it also uses its wings as an umbrella to block sunlight and create shade, making it easier to spot fish. By holding its wings above its head, the heron effectively eliminates glare and can better see fish in the water, demonstrating a clear example of exaptation.

原文:Exhaptations Exaptations(应为 Exaptations,而非 Exhaptations) is when animals use existing physical features for new purposes. The professor illustrated this with the example of harem heron(应为 heron,而非 harem) birds who live around African rivers. They often walk around the shallow waters and find fish in it to eat. But the problem with that is that it's difficult for them to see the fish with the reflections of sunlight, and they found a solution that involves the use of wings. So the birds first use wings to fly, but in this circumstance, they also use their wings to block the sun to create a shade. So they put their wings over their head and hold it there and look down, which the wing will help them to block the sun and all those illuminate reflex illuminated reflections(应为 illuminated reflections,而非 illuminate reflex),which will help them to see the fish clearly and catch them for food.

修订版(140词):

Exaptations occur when animals utilize their existing physical features for new purposes. The professor illustrated this concept using the example of heron birds living near African rivers. These birds often wade through shallow waters in search of fish to eat. However, they face difficulty seeing fish due to sunlight reflections on the water's surface. To overcome this challenge, herons have developed a solution involving their wings. Initially used for flying, herons now also employ their wings to block sunlight, creating shade. By holding their wings above their heads and looking down into the water, herons effectively block sunlight and eliminate illuminated reflections, enabling them to see fish more clearly and catch them for food. This example demonstrates how herons have adapted their existing physical features to address new challenges in their environment, exemplifying the concept of exaptation.

5.语言使用

Original: This example of the horn heron (原文中的“horn”应为“heron”,因为这里讨论的是鹭鸟,而非角) illustrates a competition exaptation (原文中的“competition”应为“exaptation”,因为这里讨论的是物种利用现有特征进行新功能适应的过程,而非竞争) because it involved the bear heron (原文中的“bear”应为“heron”,因为这里讨论的是鹭鸟,而非熊) using its existing physical features, its wings, for a new proposal purpose (原文中的“proposal”应为“purpose”,因为这里讨论的是物种利用现有特征进行新功能适应的目的,而非提议). Originally, the horn's heron's wings were used for flight, but over time, the horn heron started using its wings to block the sun and create shade when looking for fish in the water by holding its wings above its head. The horn heron for formed (原文中的“for”应为“formed”,因为这里讨论的是鹭鸟如何形成遮阳的动作,而非为了什么目的) a canopy that blocks the sun's glare, allowing it to see the fish more easily. So in this case, the horn heron ecopter adapted (原文中的“ecopter”应为“adapted”,因为这里讨论的是鹭鸟如何适应新环境,而非某种设备) its wings using them for both flying and creating shade, also adapting to the challenge of finding fish in the presence of sunlight. These demonstrate how animals can repurpose their existing features to respond to additional challenges in their environment.

Revised (140 words): This example of the heron illustrates exaptation because it involves the heron using its existing physical features, specifically its wings, for a new purpose. Originally, the heron's wings were used for flight; however, over time, the heron began utilizing its wings to block sunlight and create shade while searching for fish in the water. By holding its wings above its head, the heron forms a canopy that effectively blocks the sun's glare, enabling it to see the fish more easily. In this case, the heron adapted its wings for dual purposes: flying and creating shade, thereby addressing the challenge of locating fish in sunlit waters. This example demonstrates how animals can repurpose their existing features to respond to additional challenges in their environment, showcasing the concept of exaptation.
