another would enter and ask for a price lower than the first. In this way, each of the others would offer a price lower than the one before, and the last of his friends made a great effort to attempt to get it at the lowest price. Before long Balzac himself would return, offer more than the last two or three persons made and trust to luck. The plan worked--- Balzac got the vase at his price!

A telescope (望远镜), called Gaia, is being designed by astronomers in Europe, and it couldn’t be

more different from Pan-STARRS, which is another telescope being designed. While Pan-STARRS will be looking for asteroids (小行星) and comets headed for Earth, Gaia will be looking at our entire galaxy (银河系).

Gaia is designed to draw a map of the Milky Way, our home galaxy. Just as a map of your town

gives you a picture of where things are located, Gaia’s map of the galaxy will tell astronomers where the stars are. Over five years, Gaia will observe (观察) about a billion stars and other objects in our galaxy. Each object will be observed about 70 times.

Gaia will be sent into space connected to a rocket. It contains two telescopes, each focused at a

different angle (角度). These two telescopes act like Gaia’s “eyes”. The reason why humans can see things in 3D is that we have two eyes focused on the same object, at slightly different angles. By using two telescopes like eyes, Gaia can produce the first 3D map of the positions of the stars it views.

Gaia, which is to be sent into space in 2011, will be a powerful telescope. If you were to use it on

Earth, for example, you could stand 600 miles away from your best friends and still get a clear picture of their hair.

Gaia is one of more than a dozen telescopes being designed by scientists right now. with all its planets, stars and other strange objects, is a puzzle with pieces that we can see by using powerful telescopes.

32. How many different angles can Gaia focus at each time?

A. 2. B. 3. C. 4. D. 5.

33. The map to be drawn by Gaia ______.

A. can show every building on Earth

C. will just show the stars around Earth

D. will show where the stars are in our home galaxy

A. What Gaia will do in space. B. When Gaia will start to work.

C. How powerful Gaia will be. D. What Gaia will do to Earth.
