四、阅读理解（每小题 2 分，共 10 分）
When we talk about Earth and Beyond, we need to think both about protecting our home and exploring the universe.
The earth is facing many problems now: air pollution, water shortage and global warming. These problems make our planet less suitable to live on. So we must take action to protect it. We can use renewable energy like solar power, recycle waste and plant more trees.
At the same time, humans keep exploring outer space. We have sent spacecraft to Mars and discovered many exoplanets. Space exploration helps us learn more about the universe. It also teaches us how precious the earth is. Every space mission requires teamwork and careful preparation. Astronauts and scientists work together to overcome difficulties like weightlessness and radiation.
Some people wonder if we can move to other planets one day. But so far, no planet has been found to be as suitable as the earth. So protecting our home is still the most important task.
Space exploration and earth protection are not opposite. They can help each other. The technology used in space exploration can also help us solve earth's problems. For example, satellite technology helps us monitor climate change and natural disasters.

八、任务型阅读（每小题 2 分，共 10 分）
Earth and Beyond is a topic that connects our home planet with the universe. Protecting the earth and exploring space are both important for humans.
First, the earth is our only home. It provides us with everything we need to live. But now it's facing serious problems like air pollution and global warming. We must take action to protect it. Small acts like turning off lights when leaving rooms can make a big difference.
Second, space exploration helps us learn more about the universe. We have sent spacecraft to the moon, Mars and other planets. These missions help us understand how the universe works. They also teach us how precious the earth is.
Third, space technology can help solve earth's problems. For example, satellites can monitor weather changes and natural disasters. This helps us take action early to reduce damage.
Finally, many teenagers are interested in space science. They dream of becoming astronauts or scientists. These dreams encourage them to learn more about science and technology.

Earth and Our Space Dream
Earth is our warm home, but the universe outside is also mysterious. Protecting the earth and exploring space are equally important.
Scientists launch spacecraft to explore distant planets, and every space mission needs people to cooperate closely. They make full preparations in case unexpected problems happen. While exploring space, we realize how fragile the earth is, so we should cherish it more.
My dream is to become a space scientist. I want to join a space mission to explore unknown planets, and also use space technology to protect our earth. I will study hard to make my dream come true.
