三、提升题课后，Mike 查阅了一些月球的相关资料。请阅读短文，回答下列问题。
The Moon is Earth's neighbour in space. There is no air or water on the Moon, so no living things can live there. There is no wind or rain, so people's footprints(足迹) can stay there for a very long time. The Moon looks bright at night, but it has no light of its own(自己的). It gets light from the Sun. Sometimes we see a round full moon, and sometimes we see a crescent moon(新月) like a banana. The Moon changes its shape(形状) because it moves around Earth.
1. Why can't living things live on the Moon?

2. Will people's footprints stay on the Moon for a long time? Why?

3. Does the Moon have its own light? Where does the Moon get light from?
