三个选项中选出最佳答案。每段对话或独白读两遍。
听下面一段对话，回答第6至第7小题。

W: It says two astronauts have gone to the space station.
M: What will they do there?
W: They will get some information about the other planets.
M: When will they come back to Earth?
W: About two days later.
听下面一段独白，回答第8至第10小题。
Comets are like space travelers. They can change their shapes and looks as they get
closer to the Sun. What’s more, they’re one of the oldest objects in our solar system, so
studying them is like looking back in time.
Comets are old. They were born for billions of years. They are almost as old as
第 1 页 共 6 页our solar system. Comets are visitors. They don’t live in our solar systems forever.
They come from far away and visit the solar system sometimes. Comets are
sometimes dangerous. Because during their visits, they may lose their way and hit
Earth. This may bring great harm to lives on Earth. Luckily, we can also explore
comets when they get close to us. Scientists study comets because they carry
information about how the solar system was formed.
听下面一段对话，回答第11至第15小题。
M: I just read a report about the exploration of Mars. It’s really exciting.
W: Oh? What’s so special about Mars?
M: There are some signs saying there was water on Mars in the past.
W: That’s really interesting. So if there was water on the planet, what can scientists
prove?
M: Well, if there was water, there might be lives like us on Mars.
W: I see. But space exploration costs a lot of money.
M: I know, but it’s very important. It can help us understand the universe better. And in the
future, it may bring us many benefits, like new materials and a new planet to live on.
第三节
听下面一篇短文，根据你所听到的内容，在信息表中相应的横线上填入所缺信
息，每空限填一词。短文读两遍。
Venus is close and similar to Earth. It is often described as the sister of Earth.
Scientists have studied Venus for a long time since 1961. In the past, they thought there
was water, plants and animals on Venus. But now they find that the temperature is so high
that there isn’t any water or living things. There are only mountains and volcanoes. The
sky on Venus is yellow and orange. It’s because of its thick clouds. Until now, scientists
have sent over 40 machines into space to watch Venus and they hope to learn more about
it.

My Favorite Planet—Jupiter
Jupiter is the biggest planet in our solar system. It’s much larger than all the other planets
together.
There is one thing very special on Jupiter—the Great Red Spot. It’s a huge storm.
This storm lasts for a long time. Jupiter has many moons. One of its moons is called Europa.
Scientists think there may be liquid water on Europa. Water is very important because where
there is water, there might be life.
Scientists like Jupiter a lot. They study it all the time. They want to know more about
Jupiter and the universe. I like Jupiter too. It’s so interesting and there’s so much to learn
about it.
