Scientists think that there has been life on the earth for hundreds of millions of years. However, we haven't found life on other plants yet. Why not?

The Earth is a planet and it goes around the Sun. Seven other planets also go around the sun. None of them has an environment with air, so people and living things cannot grow. The Sun and its planets are called the solar system(太阳系). The solar system is a small part of our galaxy（星系）.

But scientists have discovered many other galaxies in the universe. But they are far away and their light has to travel for many years to reach us. It is hard to understand how large the universe is.

So far, scientists have sent lots of spaceships to look at other plants in our solar system, and some spaceships have gone beyond the solar system. However, no one has discovered any life in space yet.

But why has no one from other plants sent us a message? Have they tried to send information to us? With so many stars in the universe, are we alone, or is there life out there in space? We don't know yet.

1.How many planets go around the sun?

A.Seven B.Eight C.Nine D.Ten

2.In order to look at other planets in the solar system, scientists have sent many________.

A.e-mails B.planes C.spaceships D.messages

Scientists think that there has been life on the earth for hundreds of millions of years. However, we have not found life on any other planets yet.

The earth is a planet and it goes around the sun, which is a star. Seven other planets also go around the sun. None of them has an environment like that of the earth, so scientists do not think they will find people and things on them. The sun and its planets are called the solar system (太阳系). The solar system is a small part of our galaxy (星系). There are billions of stars in the Galaxy, and our sun is only one of them.

Scientists have also discovered many other galaxies in the universe (宇宙). They are very far away and their light has to travel for many years to reach us. So how large is the universe? It is impossible to imagine.

Scientists have sent spaceships to the planet Mars (火星) to take photos. They have even sent spaceships to travel outside the solar system. However, no spaceship has travelled far enough to reach other stars in our Galaxy.

Scientists have always asked questions: with so many stars in the universe, are we alone, or is there life out there in space? Have there been visitors to the earth from other planets? Why has no one communicated with us? We do not know the answers… yet.

根据短文内容，判断下列句子正误。正确的用“A”表示，不正确的用“B”表示。

1.There are eight planets in the solar system.

2.There is more than one galaxy in the solar system.

3.The light from the stars in other galaxies has to travel for a long time to reach the earth.

4.Spaceships have visited most of the universe.

5. Scientists have received many messages from space.
