专题 03 完成图表 unit 4 Amazing Plants and Animals 【基础训练】 难度:★★★ 一、根据短文内容,完成图表中所缺信息。 How do you know when summer is near Is it the sweet smell of gardenias Or maybe the sounds of cicadas Did you know there's a science to understanding the timing of these seasonal events or their changes It's called phenology (物候学). Phenology is a key part of life on Earth. Many birds time their nesting (筑巢). They make sure that their eggs hatch (孵化) when many insects appear so that they can feed their babies. Many farmers and gardeners use phenology too, often without even realizing it. For example, they plant carrots and cabbages when the first lilac leaves appear. Phenology affects many things in nature, including water and carbon cycles (碳循环). These cycles play a key role in deciding the Earth's climate. But because of climate change, many phonological events are now changing. Spring events are taking place earlier now than in the past, and fall events are happening later. Scientists aren't sure what these changes mean for biological systems. But many problems could come. One of them is called phonological mismatch. This happens when animals and plants respond (作出反应) differently to climate change. Animals and plants that depend on (依靠) each other can even lose their lives. For example, if a plant flowers before the pollinators arrive, both the plant and the pollinators might have trouble living. If you're interested in these cycles of cause and result, you can take a closer look at some phonological events. Record the weather every day and when different plants bud and flower. After several years, you'll notice that these events don't happen at the same time every year. At the very least, you'll get a better understanding of how climate change is affecting the world around us.

And they have different kinds of ways to do this. The simplest way is gravity (重力). When the fruit gets too heavy, it falls from a tree to the ground.
