5.Language Use

Original: According to the lecture, there are two reasons why some plants avoid light. The first reason is that some plants may depend on some objects to support themselves to live. A good example of this is the winged vine plant. Some wings may live in shadow until they reach the trees or buildings to support their life. Another reason is that some plants may avoid exposure to the sun's ray. To illustrate, if the sunlight is too intense, the plants will lose so much water, thus get dried out. Therefore, to avoid the intense sunlight, the plant will change their position of leaves. A good example of this is the bean plant, which turns their leaves away when exposed to the strong sunlight.

(The word "winged" was replaced with "vine" for accuracy and clarity.)

Revised (140 words): According to the lecture, there are two primary reasons why certain plants avoid light. The first reason is that some plants rely on external objects for support in order to grow properly. A prime example of this is the vine plant, which grows in shadows until it reaches a tree or building for support. The second reason is that certain plants need to minimize exposure to sunlight in order to conserve moisture. For instance, when sunlight becomes too intense, plants risk losing excessive amounts of water and consequently drying out. To counteract this issue, these plants adjust the position of their leaves to reduce exposure. A notable example of this adaptation can be observed in bean plants, which rotate their leaves away from direct sunlight when exposed to harsh conditions. By employing these strategies, both vine and bean plants effectively avoid light for their respective reasons.

Original Answer: The lecture explains two reasons that some plants avoid light. The first reason is they need other objects to grow on for support. So they are attracted to a dark shadow. For instance, vines grow in dark shadows until they reach a tree or a building. After they reach there, they are grown to climb up and grow on that object. The other reason is that the plants need to conserve moisture. When they are exposed to intense sunlight, they will lose water. So they need to change their position of leaves for retaining moisture. Take a sort of bean plant for instance. When they sense the strong sunlight, they are going to change their leaf to the side way. In this case, they can avoid being dried out. These are two strategies plants use to avoid light.

Corrected Answer: The lecture discusses two reasons why some plants avoid light. The first reason is their need for other objects to grow on for support. As a result, they are attracted to dark shadows. For example, vines grow in dark shadows until they find a tree or a building. Once they reach it, they climb up and grow on that object. The second reason is the plants' need to conserve moisture. When exposed to intense sunlight, they lose water and must adjust the position of their leaves to retain moisture. Consider the bean plant as an example; when it senses strong sunlight, it changes its leaves' orientation sideways so that only the thin edge faces the sun, preventing them from drying out. (原文中的“they are grown”改为“they climb”，因为这样更自然。另外，将“a sort of bean plant”改为“the bean plant”，以保持一致性。) These are two strategies plants use to avoid light.

5.Language Use

Original Answer: In the biology lecture, the professor talks about two reasons that some plants avoid light. The first is they need other objects to grow up, and so before they touch another object, they just grow in the dark shadow. For example, some kind of vines, they grow in the shadow until they reach the object, and then they grow straight on. Also, the second reason is that they need to conserve the moisture because the intense sunlight will decrease the water contained in the in the plant, so it is dangerous for the plant to dry out, so they usually change position. For example, a kind of bean, when they sense that the sun is too strong, they just change their side of the leaf to make it face to the sunlight, and it helps to avoid to dry out and to contain the water, so this is two reasons that some plants avoid light.

Corrected Answer: In the biology lecture, the professor talks about two reasons that some plants avoid light. The first is they that these plants need other objects to grow up support their growth(to make it clearer), and so before they touch another object, they just grow in the dark shadow dark shadows(to maintain consistency). For example, some kind of vines types of vines(to sound more natural), grow in shadows until they reach an object and then grow straight on. Also Additionally(to improve transitions), the second reason is that they need to conserve moisture because intense sunlight will decrease the water contained in the plant, making it dangerous for the plant to dry out. To prevent this, they usually change position. For example, a species of bean plant senses when the sun is too strong and adjusts the position of its leaves to face away from the sunlight, helping to avoid drying out and retain moisture. These are two reasons why some plants avoid light.

Revised Answer (140 words): In the biology lecture, the professor discusses two reasons why some plants avoid light. Firstly, these plants require other objects for support during growth. They grow in dark shadows until they find a suitable object, such as a tree or building. For instance, certain types of vines follow this pattern, growing in shadows until they can climb an object for support. Secondly, some plants need to conserve moisture due to intense sunlight causing water loss. To prevent drying out, these plants adjust their positions accordingly. A species of bean plant exemplifies this behavior by changing the orientation of its leaves when sensing strong sunlight, allowing it to avoid excessive water loss and maintain moisture levels. These examples demonstrate two key reasons behind certain plants' tendency to avoid light.

Original Answer: Many plants were willing to be seek the sunlight to get enough shine, and there are many plants that will avoid the light. In the lecture, the professor used two reasons to illustrate it. The first one is that some plants need some objects like trees to support themselves. Even though the lights under the trees are dark, these plants will grow along the tree. This is one example. It is a kind of plant that is growing in a shadow under the trees or under the building. The second reason is that the dark environment helps the plants to conserve their moisture. When it is exposed to the sunlight, it is dangerous for some plants because they will lose some moisture. But under the dark environment, it is more safe. Take the bean plant as an example. Under the middle of the day, it will still live in order to protect itself.

(将“were willing to be”改为“seek”，使句子更自然。)

Revised Answer (140 words): In the lecture, we learn that some plants seek sunlight while others avoid it for various reasons. The professor provided two examples to illustrate this phenomenon. Firstly, certain plants require objects like trees for support and grow towards darker areas where these objects cast shadows. For instance, vines grow in shadows until they reach a tree or building, then climb up for support.

Secondly, some plants avoid light to conserve moisture as intense sunlight can cause them to lose water and dry out. For example, a species of bean plant changes its leaves' position during intense sunlight in order to minimize exposure and retain moisture.

In conclusion, while many plants seek sunlight for growth, others like vines and bean plants avoid light for reasons such as finding support or conserving moisture.

Original Answer: The biology lecture discusses the reason why some plants avoid the sun. First, some plants need to find other objects like trees to cling to, attracted by the shadow of tall objects. These plants grow along the shadow of tall objects. For instance, why plants grow up in shadows until they reach tall objects like trees or buildings, so that they can grow up less objects? Second, certain plants conserve their moisture by avoiding the sun, because intense sunlight makes these plants lose water. During the day when sunlight is strong, some plants change their direction of leaves, decreasing the exposure to sun. In the example of bean present, when sunlight is too strong in the middle of the day, bean plants will turn leaves into sideways, avoiding drying out. These three examples illustrate the reason why.

Corrected Answer: The biology lecture discusses the reasons why some plants avoid light. First, some plants need to find other objects(原文中的表达不够清晰，改为更自然的表达方式) like trees to cling to, attracted by the shadow of tall objects. These plants grow along the shadows cast by tall objects. For instance, vines grow in shadows until they reach tall objects like trees or buildings, so that they can be supported by them(修改了原文中的疑问句，使其更符合语境). Second, certain plants conserve their moisture by avoiding light, because intense sunlight makes these plants lose water. During the day when sunlight is strong, some plants change the position of their leaves, decreasing the exposure to light. In the example of the bean plant, when sunlight is too strong in the middle of the day, bean plants will turn their leaves sideways, avoiding drying out. These two examples illustrate the reasons why(修改了原文中的数字，使其与问题相符).

The speaker's delivery is mostly clear and fluid, but there are some occasional pauses that disrupt the flow of speech. To improve, the speaker should practice speaking more consistently and work on reducing unnecessary pauses. Additionally, the speaker should focus on accurate pronunciation to avoid any spelling errors that may arise from mispronunciation.

4.Topic Development The response is coherent and well-organized, with clear connections between ideas and sufficient support or examples. However, there is room for improvement in terms of providing more specific details about the vine and bean plant examples. The speaker could also work on refining their language use to make their explanations more concise and precise. Overall, practicing and refining these aspects will lead to a stronger topic development in future responses.

5.Language Use

Original: The professor goes into a tonlot ("ton" is informal, use "lot" for a more formal tone) of detail about the plants which are avoiding the sunlight. Many plants want to get sunlight because they want to grow taller, while on the other hand many plants don't want to meetreceive (use "receive" instead of "meet" for clarity) the sunlight during the day. For one example is the vines. Vines grow in dark shadows which are covered by tall trees. They grow on tall trees and grow taller. Secondly, the professor said many plants don't want to get sunlight because sunlight can lead to the evaporation in the plant's leaves. Plants want to retain their moisture, such as the bean plant. When they think the sunlight is too strong, they put their leaves sideways, therefore it can retain their moisture.

Revised (140 words): The professor provides a lot of detail about plants that avoid sunlight. Some plants seek sunlight to grow taller, while others prefer not to receive excessive sunlight during the day. One example is vines, which grow in dark shadows cast by tall trees. These vines rely on trees for support as they grow upward. Another example mentioned by the professor is that many plants avoid direct sunlight to prevent excessive evaporation from their leaves and conserve moisture. The bean plant serves as an illustration of this strategy; when exposed to intense sunlight, it adjusts its leaves' position sideways, reducing exposure and retaining moisture more effectively. By understanding these examples, we can appreciate the diverse ways in which plants adapt to their environment and optimize their growth.

Original Answer: There are two reasons that some plants avoid light. The lecturer elaborates the first reason by the example of the vine. The vines just live in the dark shadow of the trees to climb on the tree and finally reach the top, which in order to grow up in a higher place to reach more sunlight later. The second reason that some plants do this is to conserve moisture. The lecturer takes the bean plant as an example. When in the middle of the day, the intense sunlight may cause the bean tree to lose water, the bean plant just changes the position of the leaf and lets it side post the sun to avoid the service of self-exposure to the sun to conserve more moisture, which avoids them from drying up.

Corrected Answer: There are two reasons that some plants avoid light. The lecturer elaborates on the first reason using (用)the example of a vine(一种藤蔓植物). Vines grow in the dark shadows of trees(树的阴影处), climb up them, and eventually reach their tops(最终到达顶部). This allows vines to access more sunlight at higher elevations later on. The second reason some plants avoid light is to conserve moisture. The lecturer uses a bean plant as an example. In intense midday sunlight, bean plants risk losing water. To prevent this, they change the position of their leaves, turning them sideways to minimize exposure to the sun and conserve moisture, thus preventing them from drying out.

Original Answer: Should professor use the examples of the wine vine and the bean plant discussed two reasons that some counsel white lies? One is the wine vine tree, it can make the shadow and conserve the moisture, and it's too awkward. And the bean plant, it is dangerous to dry and it can maintain the moisture.

(原文中的 "wine" 应改为 "vine"，因为这里讨论的是藤蔓植物。)

Corrected Answer: The professor discussed two reasons why some plants avoid light using the examples of the vine and the bean plant. One reason is that plants like vines grow in shadows to find tall objects for support, eventually climbing up these objects. Another reason is that some plants, such as bean plants, change the position of their leaves to reduce exposure to intense sunlight and conserve moisture.

Revised 140-word Answer: The professor explained two reasons why certain plants avoid light by using examples of vines and bean plants. Firstly, some plants like vines actively grow in shadows to locate tall objects like trees or buildings for support. Once they reach these objects, they climb or grow upwards along them. This behavior allows them to find a stable structure to grow on while avoiding direct sunlight. Secondly, other plants such as bean plants have developed mechanisms to conserve moisture by reducing their exposure to intense sunlight. They achieve this by changing the position of their leaves during periods of strong sunlight, turning them sideways so that only the thin edges are exposed to the sun's rays. This adaptation helps them retain moisture and prevents them from drying out due to excessive sunlight exposure.

These plants are attracted to dark shadows cast by tall objects, allowing them to eventually reach these objects and grow upward along them.

The second example is the bean plant, which changes its leaf position during intense sunlight to conserve moisture. When exposed to strong sunlight, plants tend to lose water and risk drying out. To prevent this, bean plants turn their leaves sideways so that only their thin edges are exposed to the sun, reducing water loss and helping them retain moisture.

In conclusion, plants like vines and bean plants avoid light to either find support for growth or conserve moisture, demonstrating their adaptability to different environmental conditions.

4.话题发展 回答内容基本上是连贯和组织良好的，但在解释植物避光原因时可以更加详细。例如，在解释藤蔓如何寻找支撑物时，可以提到它们是如何被高物体投射的阴影所吸引，并沿着阴影生长直至找到支撑物。在谈到豆类植物保持水分时，可以强调它们是如何通过改变叶子的位置来减少阳光暴露面积。总之，在练习中尝试提供更多细节和例证以增强话题发展。

5.语言使用

原文：In the lecture, the professor discusses two reasons why plants grow away from sunlight. In the lecture, the professor explains two reasons why some plants avoid sunlight.（将“grow away from”改为“avoid”，使表达更自然。）

原文：The first reason is that plants would grow in the shadow and find some tall object to cling to. The first reason is that certain plants grow in shadows to find tall objects for support.（将“would grow”改为“grow”，使句子更简洁；将“some tall object”改为“tall objects”，使表达更准确。）

原文：For example, the vine always grow in the shadow of trees or buildings until they can climb up the trees or buildings to grow away from sunlight. For example, vines typically grow in the shadows of trees or buildings until they can climb up and be supported by these structures, thus avoiding direct sunlight.（将“always”改为“typically”，使表达更自然；将“grow away from sunlight”改为“avoiding direct sunlight”，使句子更连贯。）

原文：The second reason is that the plants can conserve their moisture. The second reason is that some plants avoid light to conserve moisture.（将“the plants”改为“some plants”，使表达更准确；添加“avoid light”，使句子更完整。）

原文：If the sunlight is too strong, the plant would turn its side to another round to decrease the loss of water. If the sunlight is too intense, the plant adjusts its position to minimize water loss.（将“too strong”改为“too intense”，使表达更准确；将“turn its side to another round”改为“adjusts its position”，使句子更简洁。）

原文：For example, when the sunlight is too strong, the bean plant would turn its side to another round to avoid drying out its leaf. For instance, when the sunlight is too intense, the bean plant repositions its leaves to prevent them from drying out.（将“too strong”改为“too intense”，使表达更准确；将“turn its side to another round”改为“repositions”，使句子更简洁；将“its leaf”改为“them”，使表达更自然。）

Revised Answer (140 words):

In the lecture, the professor explains two reasons why some plants avoid sunlight. The first reason is that certain plants grow in shadows to find tall objects for support. For example, vines typically grow in the shadows of trees or buildings until they can climb up and be supported by these structures, thus avoiding direct sunlight. The second reason is that some plants avoid light to conserve moisture. If the sunlight is too intense, the plant adjusts its position to minimize water loss. For instance, when the sunlight is too intense, the bean plant repositions its leaves to prevent them from drying out. Therefore, these are two reasons why some plants avoid sunlight.
