十、阅读理解（判断对错，对的写T，错的写F）（15分）
Passage 1
The Amazon rainforest is the largest rainforest in the world. It covers most of northern South America. The rainforest is home to millions of plants and animals. Many of them can only be found in the Amazon.
The Amazon rainforest is also called the “lungs of the earth” because it produces about 20% of the world’s oxygen. It helps to control the world’s climate and keep the air clean. However, the rainforest is in danger. People are cutting down trees to make space for farms and factories. This is called deforestation. Deforestation is causing many animals and plants to die out. It also contributes to global warming.
Many countries and organizations are working to protect the Amazon rainforest. They are making laws to stop deforestation. They are also teaching people about the importance of the rainforest. We can also help by reducing the use of products that come from deforestation, such as certain kinds of wood and paper.

Passage 2
A survey was conducted among 500 middle school students about their knowledge of the natural world. Here are the results:
Only 30% of the students know that the Amazon rainforest is called the “lungs of the earth”. 45% of the students can name three or more endangered animals. 60% of the students have participated in environmental activities, such as tree planting and rubbish collection. However, 70% of the students don’t know how to save energy in daily life.
The survey also found that students who often watch nature documentaries or read nature books have better knowledge of the natural world. They are also more willing to take part in environmental protection activities.
Most students said they want to learn more about the natural world. They hope their school can organize more activities related to environmental protection, such as field trips to nature reserves and lectures by environmental experts.
