They have roots that grow above the ground, which help them survive in salty water. These unique trees are incredibly important for both wildlife and people. Mangrove forests are home to many species of fish, birds, and other animals. The roots provide shelter for young fish and protect them from larger predators. Birds nest in the branches, and monkeys and snakes live among the trees. Mangroves are also breeding grounds for many marine species. Mangroves protect coastlines from storms, floods, and erosion. Their strong roots hold the soil together and reduce the impact of waves. During tsunamis, mangroves have saved many lives by absorbing the force of the water. In some places, mangroves are more effective than man-made barriers. Unfortunately, mangroves are being destroyed at an alarming rate. Many have been cut down to make way for shrimp farms, tourist resorts, and coastal development. Pollution also harms them. In the past 50 years, the world has lost about 35% of its mangroves. Conservation groups are working to protect and restore mangrove forests. They plant new trees and educate local communities about their value. When mangroves are protected, they continue to provide food, shelter, and protection for both wildlife and people. 1. What makes mangroves able to survive in salty water? A. Their leaves. B. Their special roots. C. Their flowers. D. Their fruit. 2. How do mangroves protect coastlines from storms? A. They block the wind. B. They hold the soil and reduce wave impact. C. They grow very tall. D. They attract birds. 3. What percentage of mangroves has been lost in the past 50 years? A. About 25%. B. About 35%. C. About 45%. D. About 55%. 4. What is one reason mangroves are being destroyed? A. They grow too fast. B. They are not useful to people. C. They are cut down for shrimp farms and development. D. They attract too many insects. 八、阅读还原 The Importance of Nature Reserves Nature reserves are protected areas where wild animals and plants can live safely. 1.______________ They are like homes where animals can live without fear of being hunted or losing their habitats. There are many reasons why nature reserves are important. First, they protect biodiversity (生物多样性). 2.______________ Second, they help scientists study wild animals and plants in their natural environment. 3.______________ Nature reserves also help people. They protect forests, clean water and fresh air. 4.______________ They also provide opportunities for people to enjoy nature and learn about wildlife.

Many people are afraid of them, but bats are actually amazing creatures that play a vital role in our ecosystem. They are the only mammals that can truly fly. How Bats Help Humans Bats are natural pest controllers. A single bat can eat up to 1,000 insects in one hour! This helps farmers protect their crops without using harmful pesticides. In fact, bats save farmers billions of dollars every year in pest control. Some bats also help pollinate flowers and spread seeds. Fruit bats, for example, eat fruit and spread the seeds to new areas, helping forests grow. Challenges Bats Face Despite their importance, bats are in danger. One of the biggest threats is a disease called white-nose syndrome. This disease has killed millions of bats in North America. Habitat loss is another serious problem. When forests are cut down, bats lose their homes. Wind turbines can also kill bats when they fly into the blades. In some places, people still kill bats because they are afraid of them or think they cause harm. Why We Need Bats Without bats, ecosystems would be seriously damaged. The number of insects would increase dramatically, damaging crops and spreading diseases. Forests would not grow as well without bats to spread seeds. Scientists estimate that bats contribute about $3 billion to the US economy every year just through pest control. How to Help Bats There are many ways we can help bats. We can build bat houses to give them safe places to sleep. We can protect caves where bats live during the winter. We can also support conservation organizations that work to study and protect bats. Learning about bats and sharing our knowledge with others can help reduce the fear that leads to their harm. Small actions can make a big difference. A. 选择填空 1.
