【题目】 With China’s large population and increasing urban(城市的)space, the cost of electricity is rising in cities. So the Chinese government is preparing to send the world’s first artificial(人造的)moon to space.

The man-made moon is, in fact, a satellite. It carries a huge space mirror so that it can throw back sunlight to the Earth. The moon will fly about 500 kilometres above Chengdu, a south-western city of China, and work like the Moon at night. Since it runs much closer to the Earth than the Moon, it’s much brighter and there will be no need to use street lights in the city. According to scientists, Chengdu can save around 174 million dollars in electricity if the man-made moon brightens 50 square kilometres of the city.

For now, the artificial moon is still going through testing. Although it has many advantages, quite a lot of people think that creating more artificial light is harmful to the environment, as light pollution is a growing problem in our modern world. Actually, there is no need to worry. Chinese scientists say the mirror on the moon can be controlled, so they can decide its direction, brightness and so on. They can even turn it off when needed. Moreover, when the man-made moon works, people will see only a bright star above. It won’t be a giant moon as imagined.

Several countries, including China, are all looking to use energy from space, and artificial moons have been under discussion for some time. In 1999, Russia tried sending a space mirror into space, but it failed. And later the project was cancelled, according to the New York Times. And now, it seems that space light has come closer.

1China will send the man-made moon to space to __________.

A.study the MoonB.explore spaceC.save energyD.protect the Earth

2What is the second paragraph mainly talking about?

A.How the man-made moon works.B.How the man-made moon was created.

C.How scientists control the man-made moon.D.How the man-made moon throws back sunlight.

3What can we learn about the man-made moon from the passage?

A.It looks huge from the Earth.B.Three will be sent to space in 2020.

C.It is designed to work at night only.D.China is the first country to send it to space.

4In which column(专栏)of a newspaper can we probably find the passage?

A.NATURE.B.ENVIRONMENT.C.SOCIETY.D.SCIENCE.
