五、Read and choose. Lily 读了一篇有关地球和火星趣味知识的短文。请你读一读，根据短文内容选择正确的答案。
Earth is our beautiful home in space. It is a blue planet with lots of water and air, so people, animals and plants can live here. Earth travels around the Sun every year, and it has only one natural neighbour — the Moon. We can see the Moon in the dark sky at night. The Moon travels around Earth every month, but there is no water or air on it. That's why no living things can live on the Moon.
Mars is a red planet far from Earth. People call it the "red planet" because of its colour. We can sometimes see Mars as a small red spot in the night sky. Scientists（科学家）find that there is water and soil on Mars, but the air is thin for living things to breathe. So there are no aliens, animals or plants on Mars. China is interested in Mars too — we put a rover on Mars to take photos and collect（收集）information. Every year, we learn more about this amazing red planet.
