A
Forests are the lungs of our planet. They help clean the air, give homes to animals, and provide us with wood, fruit, and medicine. But in many places, forests are getting smaller and smaller. This is a very serious problem because forests are importaint to us.
Why do we need forests?
Forests are in many places on Earth. They take in bad air and give us good air to breathe. They also help keep the soil safe when it rains, and they help make the weather nice. Without forests, many animals will have no home, and the weather can get very bad.
Why are forests getting smaller?
People cut down trees to build houses, make farms, or make new roads.

Sometimes, there are also big fires in forests when the weather is too dry. If this does not stop, we will not have many forests later.
What can we do?
Many countries are making rules to keep forests safe. Students can help too. They can use less paper, plant trees, or tell their friends why forests are good for us.
Remember: Forests are not just a lot of trees. They are important to animals and us. If we take care of forests, we take care of our future.

1. 通读全文可知，文章分别介绍了森林的重要性、森林面积缩小的原因，以及我们可以采取的保护森林的相关措施，对应选项C。A选项文中没有重点讲解在森林里种树的方法，B选项仅为文章开头的局部内容，不能概括全文主旨。
2. 根据划线短语所在句"They take in bad air and give us good air to breathe"，森林将有害空气留存，释放出可供呼吸的洁净空气，可推测take in的含义是“吸收”，选A。
3. 原文第一段提到森林可以为人类提供木材、水果、药材，第二段提到森林可以产出可供呼吸的新鲜空气，对应B选项。A选项的新房、新路是人们砍伐树木后建造的，并非森林直接提供；C选项中"give homes to every animal"表述错误，原文没有提到“所有动物”的相关内容。
