They can do many things that we can't. One of the most amazing things about plants is photosynthesis. Photosynthesis is the process that plants use to make their own food. They use sunlight, water from the soil, and carbon dioxide from the air. During this process, they produce oxygen, which is what we need to breathe. Another amazing thing about plants is that they can adapt (适应) to different environments. Some plants can live in very cold places, like the Arctic. Some can live in very hot and dry places, like the desert. For example, the cactus has thick stems to store water, and it has spines (刺) instead of leaves to reduce water loss. Plants also have ways to protect themselves. Some plants have thorns to keep animals away. Some plants can produce a bad smell to drive insects away. And some plants, like the Venus flytrap, can even catch and eat insects for nutrients. Plants are not only important for us to live, but they also make our world beautiful. We should love and protect plants. （ ）1. What is photosynthesis? A. The process that plants use to make food. B. The process that plants use to take in oxygen. C.

They provide us with food, oxygen, and many other things. But do you know that plants can also help us fight pollution? Some plants can absorb harmful gases from the air. For example, the spider plant (吊兰) can absorb formaldehyde (甲醛), which is a harmful gas found in many homes. The peace lily (和平百合) can absorb benzene (苯) and ammonia (氨). These plants are often called "air purifiers (净化器)" because they can make the air cleaner. Plants can also help reduce noise pollution. Trees and other tall plants can absorb sound waves, making our environment quieter. This is why many cities plant trees along the streets and in parks. In addition, plants can help prevent soil erosion. Their roots hold the soil together, so it doesn't wash away when it rains. This is very important for keeping the land fertile (肥沃的). So, plants are not only beautiful but also very useful. We should plant more plants and take good care of them. 1. What can plants provide us with? 2. Why are some plants called "air purifiers"? 3. Which plant can absorb formaldehyde? 4. How can plants help reduce noise pollution? 5. What do plants' roots do to prevent soil erosion? 参考答案： 一、语音辨别 1. A 2.
