Title: The Role of Water in Plant Growth
Water plays a crucial role in the growth and development of plants. It is essential for several key processes, including nutrient uptake, photosynthesis, and cell expansion. Plants absorb water through their roots, which then travels up the stem to the leaves. This movement of water is facilitated by a process called transpiration, in which water evaporates from the surface of the leaves, creating a pull that draws more water up from the roots.
In addition to transporting nutrients, water also helps maintain the structure of plant cells. When cells take in water, they become turgid, which provides support for the plant. Without sufficient water, plants may wilt or even die. Therefore, understanding the importance of water in plant biology is vital for both agricultural practices and environmental conservation.
听力文本（Listening Passage）
Professor:
Okay, so we were talking about how water is important for plant growth, right? Well, let me give you an example of how this works in real life. Imagine a farmer who’s trying to grow crops in a dry region. He knows that without enough water, his plants won’t thrive. But what he might not realize is that it's not just about giving the plants water — it's about how the water is distributed and when it's given.
For instance, if you water your plants too much, especially during the day, the water can evaporate quickly, and the roots won't have time to absorb it properly. On the other hand, watering them early in the morning or late in the evening can be more effective because the temperature is cooler, and the evaporation rate is lower. That way, the water has more time to reach the roots and be absorbed.
Another thing to consider is the type of soil. Some soils hold water better than others. If the soil is too sandy, it drains away quickly, and the plants may not get enough moisture. In contrast, clay soils retain water longer, but they can also become waterlogged, which is bad for root health. So, farmers need to understand these factors to optimize water usage and ensure healthy plant growth.
题目（Question）
Describe the main points of the reading passage and explain how the lecture expands on one of these points.
满分回答示例（Sample Answer）
The reading passage discusses the importance of water in plant growth, explaining that it is necessary for nutrient absorption, photosynthesis, and maintaining cell structure. It also mentions transpiration, which helps move water from the roots to the leaves.
The lecture expands on this by focusing on how the timing and method of watering affect plant health. For example, the professor explains that watering plants during the hottest part of the day can lead to rapid evaporation, making the water less effective. Instead, watering in the early morning or late evening is more efficient because the cooler temperatures reduce evaporation. This shows that while the reading emphasizes the necessity of water, the lecture highlights practical considerations for applying this knowledge in real-life situations, such as farming.
