修正后的回答（140字）：

The example from the lecture demonstrates evolution in action through the adaptation of mint plants. Initially, these plants grew in grassy fields and woods with long stems standing straight up. However, when people started building houses with front lawns, mint plants began to grow there as well. The invention of the powered lawnmower led to a rapid change in the environment, as homeowners wanted to keep their grass short. Consequently, mint plants on lawns adapted by growing sideways in a flat horizontal position instead of an upright vertical one. This allowed them to avoid being cut down by lawnmower blades. This rapid adaptation, occurring within the last hundred years, is a clear example of evolution in action.

Original: Well, the reading passage talks about the evolution in action concept of evolution in action(为了使表达更自然，添加“概念”一词), which means that evolution process the evolutionary process(使用更准确的词汇) of some species may happen more quickly than before. And for example, the mint plant, which is usually grows on woods or grassland, and after to grow lungs, it also provides perfect places for them to grow. And so they not just grow in the woods or fields. And after the invention of the moss, it cuts the grass, but also it cuts the mint. So to avoid this, they began to grow horizontally instead of vertically. So all of this evolution happened relatively in a short period of time. So it explains the concept of evolution.

Revised (140 words): The reading passage discusses the concept of evolution in action, which means that the evolutionary process for some species may occur more rapidly than previously thought. For instance, the mint plant typically grows in woods or grasslands. However, when lawns became popular as a result of urbanization, these plants found a new habitat to thrive in. Consequently, they began to grow not only in woods and fields but also on lawns. With the invention of lawnmowers, which cut both grass and mint plants, these plants adapted by growing horizontally rather than vertically to avoid being cut down. This rapid adaptation demonstrates the concept of evolution in action and highlights how species can evolve quickly in response to environmental changes.

Original: The concept of evolution in action is precisely that plants or animals evolve or change in response to sudden or rapid environmental changes. The lecturer takes the mantis mint (发音错误，应为mint) plant for example. The plant always grows in a grass field or in a wood. It always caught a long stem that stands straight up on the ground. People started to build houses in front of them. There are also some perfect places for them to grow. About 100 years ago, a long mother cut the cross to be short. The plants were also getting cut by this machine, so they did not straight up, but also grow sideways in a flat horizontal position.

Corrected: The concept of evolution in action is precisely that plants or animals evolve or change in response to sudden or rapid environmental changes. The lecturer takes the mint plant as an example. This plant typically grows in grassy fields or woods and has a long stem that stands straight up from the ground. As people started building houses with front lawns, these areas became suitable for mint plants to grow as well. About 100 years ago, the invention of the lawnmower led to shorter grass on lawns. Consequently, mint plants adapted by growing sideways in a flat horizontal position instead of straight up, allowing them to avoid being cut by lawnmowers.

Revised (140 words): The concept of evolution in action demonstrates how plants and animals evolve or adapt in response to sudden or rapid environmental changes. The lecturer uses the mint plant as an example to illustrate this phenomenon. This plant typically grows in grassy fields or woods and has a long stem that stands straight up from the ground.

This example showcases how species can rapidly adapt and evolve in response to human-induced environmental changes, highlighting the concept of evolution in action.
