四、(跨生物·物种适应性)(2025·青岛模拟改编)阅读表达。
Welcome to the Amazon rainforest. As the largest rainforest in the world,it plays an important role in keeping the balanced ecosystem on earth. With an area of around 6 million square kilometres,the Amazon rainforest is more than half the size of China. This area has a great many species. Actually,one in ten known species in the world can be found here.
There are different levels in the forest. At the bottom is a system of roots under the ground. Above that is leaf litter on the dark forest floor. The next level is made up of shorter plants with large leaves. Then there are the towering ancient hardwoods,and finally the tops of the trees which are taller than any other level of trees in the forest. Each level of the forest forms its own little world,home to different kinds of living things.
More than 1,300 species of birds and over 400 species of mammals(哺乳动物) hide among the forest's plant life. The jaguar is one example. While a large number of jaguars survive here,they are only one part of this forest's food chain. They feed on at least 87 species,including frogs. These frogs,in turn,feed on insects which eat leaves and fruit.
$The Amazon rainforest is a treasure house of species that can be used for food or medicine. What's more,the Amazon rainforest breathes life into the planet by producing over 20 percent of all the earth's oxygen(O_2). So it is often known as the "lungs of the planet".$

五、书面表达。
苏州作为新晋“国际湿地城市”,其湿地保护成果显著。请以“Protecting Suzhou's wetlands：our green treasure”为题,描述苏州的湿地的生态功能、目前面临的问题及其解决办法,鼓励人们采取行动。
Protecting Suzhou's wetlands：our green treasure______

答案： One possible version：
Protecting Suzhou's wetlands：our green treasure
Suzhou's wetlands，known as the "green lungs" of the city，play important roles：they purify water，provide homes for birds and fish，and reduce floods.
However，pollution from factories and trash left by tourists threaten these fragile ecosystems. To solve these problems，stricter laws should be enforced，and everyone can help by joining in clean-up activities. It's also a good idea to spread awareness of protecting wetlands.
Wetlands are not just nature's gift but our shared responsibility. Let's act now—reduce waste， protect wildlife，and cherish every drop of water. Together，we can ensure Suzhou's wetlands remain a vibrant treasure for generations！
