(原文中的“talks”改为“discusses”，使语言更自然。将“talks about the price will change depends”改为“refers to how the price changes depending”，使句子结构更清晰。删除“The professor,”，因为它在这里没有必要。将“changes is depend”改为“change depends”，使语法正确。将“accomplish”改为“has limited availability”，使句子更清晰。将“will be little”改为“are scarce”，以提高词汇水平。将“will rise”改为“can raise”，使语法正确。将“boat”改为“book”，纠正拼写错误。将“observe”改为“compare”，以提高词汇水平。)

Revised (140 words): The lecture mainly discusses dynamic pricing, which refers to how the price changes depending on various factors. The first factor that affects dynamic pricing is the availability of goods. For instance, if an airline has limited seat availability on a specific day and time, consumers are more willing to pay for the seats due to scarcity. Consequently, the company can raise the price and earn more profit. Another factor influencing dynamic pricing is competition among sellers offering similar products. For example, when purchasing a book online, customers can compare prices across different stores. By monitoring competitors' prices and adjusting their own accordingly, businesses can attract more customers and increase sales. Overall, dynamic pricing is a strategy that allows companies to maximize profits by considering factors such as product availability and market competition.

Original Answer: In the lecture, the professor discussed certain online marketing techniques, which is pretty questionable. The first technique involved pre-checking mail-list box during online purchase. Commonly, SEPTO encourages customers to join their marketing communication without explicit consent. While that often leads to unintentional sign-up, they do that in turn to increase their sales of their product. The second technique concerns the challenge of unscribing services like online magazines. While companies often make sign-up for them very easy, but unscribing is intentionally complex. For example, when you buy online magazines, which require you to make phone calls during specific hours to cancel their subscription, which is pretty exhausting. In conclusion, this technique, while that isn't illegal, but raises very concern.

The first technique adaptation involved pre-checking mail-list box during online purchase using body parts as natural flotation devices.

The second technique concerns the challenge of unscribing services like online magazines adaptation is the ability to remain partially alert while sleeping underwater. Dolphins are an example of this; even when their bodies are asleep, a section of their brain sends signals to swim to the surface occasionally to take breaths. In conclusion, these technique adaptations allow aquatic mammals to sleep and breathe in the ocean.

Revised Answer (140 words): In the lecture, the professor discussed the fascinating adaptations of aquatic mammals, such as whales, walruses, and dolphins, that allow them to sleep in the ocean while still being able to breathe. The first adaptation involves using body parts as natural flotation devices. For instance, walruses have large pouches or air sacs on both sides of their necks that help them float and keep their heads above water while sleeping. The second adaptation is the ability to remain partially alert while sleeping underwater. Dolphins exemplify this; even when their bodies are asleep, a section of their brain sends signals to swim to the surface occasionally to take breaths. In conclusion, these adaptations enable aquatic mammals to sleep and breathe in the ocean, showcasing their remarkable ability to adapt to their environment.

Revised Answer (140 words): In the lecture, the professor discussed certain online marketing techniques that are quite questionable in nature. The first technique involves automatically checking mailing list boxes during online purchases. Companies often encourage customers to join their marketing communications without obtaining explicit consent. This frequently leads to unintentional sign-ups, as many consumers overlook the pre-checked box, potentially resulting in increased sales for the company. The second technique pertains to the difficulty of unsubscribing from services such as online magazines or newspapers. While companies make it easy to sign up for their services, unsubscribing can be quite challenging. For instance, online magazines may require customers to make phone calls during specific hours to cancel their subscriptions, leading to ongoing charges. In conclusion, although these techniques are not illegal, they raise ethical concerns and should be carefully considered by both companies and consumers.

4.话题发展 从话题发展方面来看，这位同学的回答内容基本上是连贯和有条理的，观点之间关联明确，举例也比较充分。但在描述第一个能力时，“a vine can locate other plants by sensing their orders”这句话可以进一步完善为“a vine can locate other plants by sensing their odors and then grow towards them”。此外，在描述第二个能力时，“some plants can sense sounds that are produced by some caterpillars”可以改为“some plants can detect the sounds produced by caterpillars”。总体来说，同学可以在表述上更加精练和准确。

5.语言使用

Original Answer: The listening talks about two abilities that help plants to survive. The first ability is that some plants can sense orders odors (发音错误，应为odors). For example, a vine can locate other plants by sensing their orders odors (发音错误，应为odors), so they can smell a potato plant and move toward it and then get nutrition from it. The second ability is that they can react to some sounds and protect themselves. For instance, some plants can sense sounds that are produced by some caterpillars, and when the plants get these sounds, they can produce some chemicals and prevent some caterpillars from coming and eating them. So these are two sensory abilities that help plants to survive.

Corrected Answer: The listening discusses two abilities that aid plants in their survival. The first ability is that certain plants can detect odors (发音错误，应为odors). For example, a vine can locate other plants by sensing their odors (发音错误，应为odors) and subsequently grow towards them, enabling the vine to obtain nutrients from the potato plant. The second ability allows plants to respond to specific sounds for self-protection. For instance, some plants can detect the sounds produced by caterpillars; upon perceiving these sounds, the plants generate chemicals to deter caterpillars from approaching and consuming them. These two sensory abilities significantly contribute to plant survival.

Revised 140-word Answer: The listening discusses two essential abilities that aid plants in their survival. Firstly, certain plants can detect odors, allowing them to locate other plants. For example, a vine can sense the odors of nearby plants and grow towards them, obtaining nutrients from a potato plant in the process. Secondly, plants possess the ability to respond to specific sounds for self-protection. For instance, some plants can detect sounds produced by caterpillars; upon perceiving these sounds, they generate chemicals that deter caterpillars from approaching and consuming them. These two sensory abilities play a crucial role in ensuring plant survival by enabling them to locate resources and protect themselves from potential threats.

6.思维导图

• Main Topic: Plant Survival Abilities
  • Ability 1: Detecting odors
    • Example: Vines locating other plants
      • Obtaining nutrients from potato plants
  • Ability 2: Responding to specific sounds
    • Example: Plants detecting caterpillar sounds
      • Generating chemicals for self-protection
