2. He will start his space travel. The news sounds      ( excite).

1. We were      ( real) moved by what he said.

If you watch the sky about an hour after the sun sets，you may see some " moving stars”. But they're not real stars. They're man-made satellites. A nd the biggest of all is the International Space Station ( ISS). The ISS is the biggest man-made satellite because scientists want to live on it. Thf'y think that the [>est way to learn moiv about space is to live there.

When humans finish the space station，it will be like a city in space. People will stay and study there witli many of the things like at home. There are many lahs for space tests. The ISS is the most expensive space station. People will spend billions of dollars on it.

Scientists hope that the ISS will be a stepping stone(跳板)for future space exploration (探索).

"The ISS will help us better understand the human body, the space and the earth. It can help make our life on earth better," said Kathryn Clark, an ISS scientist.

Sixteen countries are part of the program： the US, Russia, Canada, Japan, Brazil and 11 European countries. China is not among them, but it helped with some of the experiments. In 2003 ，China sent some rice to the ISS to find out what space would do to it.

When scientists finish the International Space Station, more than 90% of the world's people can see it. So keep looking up, and maybe you'll see it get bigger.
