原文：Exhortation Exaptation(这里应该是“异化适应”，而不是“敦促”) is a phenomenon while where(这里应该用“where”而不是“while”) wild animals use their body parts designed for an old purpose and use them to cope with a new situation to improve their survival. For example, the bird heron, which eat fishes fish(“fish”在这里作为复数形式更自然) in shallow waters, they are hard to see the fish below the water surface because of the sun glare. So they use their wings, which were initially used to fly, and use the wings as an umbrella to create a shade, which enables them to see the swimming fish more clearly and more easily, so that their rate of survival improved.

修订版（140词）：

Exaptation is a phenomenon where wild animals repurpose their body parts, initially designed for one function, to adapt to new situations and enhance their survival chances. A prime example is the heron, a bird that feeds on fish in shallow waters. Due to sunlight glare on the water surface, it becomes challenging for herons to spot fish swimming beneath. Ingeniously, herons have adapted by using their wings, originally meant for flying, as a makeshift umbrella to create shade. This innovative adaptation allows herons to see fish more clearly and easily, consequently improving their survival rate.

Original Answer: Well, in the reading passage, Acceptation Exaptation(接受改为异化，因为这是原文中的正确词汇) is described as a feature on some animal species to meet the environment and increase the chance to survive. In the lecture, the professor gives an example of a kind of bird which lives by rivers and marshes and eats fish under the water. But it's pretty hard for them to see the fish under the water by the sunshine on the river because there is sun reflection and the glare stops them from seeing the fish. So they use their wings to block the sun. Just like the umbrella and eliminate the disturbance of glare and reflection. This movement well and nicely illustrates the expectation.

Corrected Answer: Well, in the reading passage, Acceptation Exaptation(接受改为异化，因为这是原文中的正确词汇) is described as a feature in some animal species that adapts to their environment and increases their chances of survival. In the lecture, the professor provides an example of a type of bird that inhabits rivers and marshes and feeds on fish beneath the water's surface. However, it is quite challenging for these birds to spot fish underwater due to sunlight reflecting off the water's surface, causing glare that obstructs their view. To overcome this issue, they utilize their wings to block out sunlight, similar to an umbrella, effectively eliminating glare and reflections. This adaptation aptly demonstrates exaptation.

Revised 140-word Answer: In the reading passage, Exaptation is described as a feature in some animal species that adapts to their environment and increases their chances of survival. The lecture provides an example of a type of bird that inhabits rivers and marshes, feeding on fish beneath the water's surface. However, spotting fish underwater is challenging for these birds due to sunlight reflecting off the water's surface, causing glare that obstructs their view. To overcome this issue, they utilize their wings to block out sunlight, similar to an umbrella, effectively eliminating glare and reflections. This adaptation aptly demonstrates exaptation, showcasing how animals can repurpose existing features to address new challenges in their environment. The heron's ability to use its wings for both flying and blocking sunlight highlights the concept of exaptation and its role in enhancing an animal's chances of survival.

Acceptation Exaptation(接受改为适应，因为这是正确的术语) is defined as a phenomenon sometimes animals use existing physical features for new purpose. For instance, there is a kind of bird which called heron a heron(加上定冠词'a'，使句子更自然). They are waiting wading(等待改为涉水，因为这是正确的描述) birds and they always find fish to eat during the day. However, because of the reflection of the sun, it is hard to see the fish. So they find a solution that using their wings to block the sun. Before they use the wings to fly, it is their old purpose. But now they use it to block the sun, it is the new purpose. When looking for the fish, their wings form an umbrella which could block the sun. And they are able to see the fish much better than before, so they could find the fish easily.

Revised Answer (140 words):

Exaptation is defined as a phenomenon where animals sometimes use existing physical features for new purposes. For instance, there is a type of bird called a heron. Herons are wading birds that primarily feed on fish during the day. However, due to sunlight reflections on water surfaces, it can be difficult for them to see the fish. To overcome this challenge, herons have adapted to using their wings to block sunlight. Previously, their wings were solely used for flying; now they serve a dual purpose by also providing shade when searching for fish. By forming an umbrella-like canopy with their wings, herons can block sunlight and reduce glare on the water, allowing them to see fish more clearly and catch them more easily. This example demonstrates how the heron's wings have undergone exaptation, adapting to serve a new function in addition to their original purpose.
