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.

To make more members of their group, plants spread (传播) their seeds to other areas. 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. When there is enough water, Up, and the right temperature, the seeds in the fruit start to come up. Sometimes animals will pick up the fruit and drop it in another area. That helps move the seeds even farther away. Apples spread this way.

Other plants use wind to spread their seeds. Dandelions (蒲公英类) are a good example of this. Dandelion seeds are so light that when wind blows, it carries dandelion seeds to new places. Maple seeds also use wind. Their seeds have long, thin leaves. When the seed falls from the tree, the leaves help it fly farther from the tree.

Some animals help plants to spread their seeds. The animals eat the seeds. When some of the

seeds leave the animals' bodies, they are in a new place. Some animals and the seeds come so close together that when they leave, the seeds stay on their bodies, and they take the seeds to other places.

Ants also help spread seeds. They bring some seeds back to their home. They only eat part of the seeds. They leave the rest of the seeds underground. After that, the seeds can start growing.

How Do Plants Spread Seeds?
The gravity	The fruit  1  so much that it falls to the ground. The seeds in it then start to grow or are moved to another area.
The  2  of the wind	Some plants' seeds are so light that the winds can carry them to new places.
The animals’  3	       Some animals eat the seeds and excrete (排泄) them in other places.        Some  4  the seeds and the seeds stay on them so they carry them to other places.        Some animals  5  the seeds underground and some of them start growing at last.

Do you know bamboo? It's a kind of amazing and useful plant. In China, people started using bamboo thousands of years ago. We can make many useful things from bamboo, such as chopsticks, paper, musical instruments, and even clothes. And guess what? Now bamboo is helping to make the earth a better place.

Every year, the world makes about 400 million tons of plastic (塑料) waste. Bamboo is a
