六、阅读短文，回答下列问题。
In the future, humans may live on the Moon. It is very different from life on Earth.
There is no air or liquid(液态的) water on the Moon. People will live in strong closed homes. These homes make clean air and keep warm inside. When people go outside, they have to wear spacesuits to breathe.
People will get water from ice under the Moon’s surface. They will build special greenhouses to grow food. Plants grow with help from machines, because there is no good soil on the Moon.
The Moon has weak gravity. People can jump much higher than on Earth. They can see our blue Earth hanging in the black sky.
Scientists will work there. They study stars and our solar system. Life on the Moon will be hard. But it helps humans learn more about space. Maybe one day, this dream will come true.
