三、阅读理解
The Amazon Rainforest is the world's biggest. It is in South America. It is so wide that it covers a little more than the half size of China! The Amazon River runs through the rainforest. It's the world's second longest river. The Amazon covers much of Brazil. The green colour on the national flag(国旗) of Brazil stands for the rainforest.
However, climate change and human activities make it "sick". Usually, the rainforest can fix itself. But now, it feels too "tired" to get better. According to a new study, many trees there may die, and the Amazon Rainforest may turn into hot, dry grasslands in a few years.
Why is the Amazon Rainforest "sick"? The Amazon is one of the world's wettest places. But since 2005, three droughts have hit the rainforest. That was because of climate change. The trees don't have enough water to grow. What's worse, as they become dry, they can easily catch fire. Besides, people cut down rainforest trees for wood. They burn the forest to make farmland. All these kinds of activities made about 17% of the rainforest disappear.
The Amazon Rainforest is like the "lungs" of our planet. The rich plants there take carbon dioxide($CO_2$) out of the air and make oxygen. They make more than 20% of the planet's oxygen. If the Amazon Rainforest "dies", there will be more $CO_2$ and our earth will become even hotter. The Amazon Rainforest is also home to over 3 million animals and plants. Many of them can't live anywhere else. They would very likely just disappear.
1. According to the passage, what is NOT the reason that makes the Amazon Rainforest "sick"?
A. There are many forest fires.
B. Climate change.
C. People cut down trees.
D. Too many animals and plants live there.
2. What will happen if the Amazon Rainforest dies?
A. People will lose their lungs.
B. Many animals and plants will die.
C. We will feel colder.
D. There will be more oxygen.
3. The underlined word "droughts" means "" in Paragraph 3.
A. too little rain
B. too cold weather
C. too much cloud
D. too much fire
4. Choose the best sentence to fill in the "" in the passage.
A. Where is the Amazon Rainforest?
B. Who lives in the Amazon Rainforest?
C. How can we protect the Amazon Rainforest?
D. What will happen if we lose the Amazon Rainforest?
