1 . It sounds like something from the field of science fiction — a space exploration into vast outer space, heading towards the Red Planet While we’re not quite ready to put a person on it, the question we ask today is:     1    

The space race saw the USSR (the Union of Soviet Socialist Republics) and USA compete to achieve firsts in spaceflight. The USSR released Sputnik 1, an artificial satellite, before anyone else,     2     Now it appears that Mars is the body of desire. While to be the first nation to land on it is an obvious draw, there are other reasons why we want to get there.

    3     You only have to look at the fossils of the dinosaurs to see the benefit of finding another habitable planet. While Mars doesn’t have the right conditions to call it home just yet, there's always the concept of terraforming-changing the environment of a planet to suit our needs.

However, not everyone agrees. Leading astrophysicist Neil deGrasse Tyson has said the concept of changing habitability of a planet is not always practical.     4    

It seems that the main reason at the moment is the search for alien (外星的) life.    5     Now seemingly dead, the potential fossils could answer questions about our own evolution and that of our planet. One theory is that bacterial life on our planet didn't start here, but was brought here via asteroid from Mars.

A．and the US landed on the moon first.

B．Instead, it makes no sense when we can simply terraform Earth because of the damage we have done to it.

C．One of these could be the survival of our species.

D．Why are so many countries interested in going to Mars?

E．It has been believed that, at one time, a certain form of life did exist in this red planet.

F．Surely inspiring a new generation to visit the stars is reasonable enough.

G．May landing on Mars inspire more people to become interested in exploring space?

2 . After decades of exploring the moon, a dramatic vision is finally becoming reality. The Guardian recently reported that a project called Lunar Codex is planning to send and store over 30,000 works on the moon from artists, writers, filmmakers, and musicians from over 150 countries and regions. The goods to be stored range from novels and paintings to music, films，and even soil from Earth.

In fact, this is not the first time that people have tried sending human legacies (遗产) to outer space. In 1969, the Apollo 12 mission carried a ceramic piece with drawings. In 1971, the Apollo 15 staff left a sculpture to honor those who had died in space exploration. What’s more famous is the Golden Record carried by spacecraft Voyager 1 and 2 from NASA in 1977, which contains human language, music and images. For example, a piece of Chinese guqin music, called Flowing Streams was included in it.

Although we don’t know who determines which symbols of human legacy get sent out to space in most projects, it’s obvious that the criteria keep changing. In the past，space heritage products only focused on space-related works; but gradually, more human-related contemporary goods which held great importance in their respective eras have been added to the list. In the Lunar Codex, films, diverse art and literary works produced by women, disabled artists, and even AI have been collected for the first time to be sent to the moon.

These changing criteria also leave space for ordinary people to imagine and think. Many people are now trying to store their DNA information digitally. Will people be able to find even more surprising and inventive ways to preserve their legacy in the future? Only time can tell.

1. What is the goal of the project?

A．To make the moon livable.	B．To show respect to artists.
C．To enrich the life of astronauts.	D．To preserve human legacies.

2. How is Paragraph 2 mainly developed?

A．By explaining reasons.	B．By giving examples.
C．By making comparisons	D．By analyzing previous data.

3. What does the change of the criteria reflect?

A．AI technology is amazing.	B．The selective rules are strict.
C．Human civilization is inclusive.	D．Space-related works are popular.

4. Where does the text most probably come from?

A．A magazine.

B．A textbook.

C．An advertisement.

D．A poster.

8 . 根据句意和提示用正确的单词把句子补充完整。

The astronauts aboard China’s Tiangong space station have given a live science lecture to Chinese students on earth. They showed     1     they worked and lived in the station. The lecture was interactive as the students on the ground were able to communicate     2     them in real time.

The space environment has many special     3     (condition) that are not available on the ground, and there are many scientific experiments that can only be done there. Although the experiments     4     (explain) by the astronauts are not unusual, they can help motivate young people to have enthusiasm (热情) for science.

With the     5     (construct) of the Tiangong space station, Chinese astronauts are able to stay in the station for a long time     6     give lectures from space. Tiangong can become a long-term classroom in space,     7     (open) the door of knowledge to people at home and abroad.

In 2013, the astronauts of Shenzhou-10 manned spaceship     8     (give)the first lecture from space to Chinese students. Now the signal is     9     (clear) and more stable thanks to the advancements in Chinese telecommunication technology.

It’s predictable that more space lectures of various forms     10     (deliver)from the Chinese space station in the future. It’s hoped that more astronauts, scientists and engineers will emerge (出现) from the students watching the lectures to carry on the exploration of the unknown.

9 . Nowadays, everyone seems to hope to go into space and live on new planets. Instead of depending on another pre-existing planet, could we make a new planet by ourselves?

First of all, if we were to live on it, we should find a good place in space to put the new planet. We would want it to be in a habitable zone, which means the planet should be at the right distance from its star to make sure there would be perfect temperatures and most importantly, liquid water.

We’d also need the right materials to make the planet. Our Earth is made up of many different elements (元素). If we made our own new planet, we’d probably want it to have similar elements and a similar structure (结构). We’d also want enough water to form some oceans.

But even if we get all of the materials, creating a new planet like Earth could have many troubles. It might be something more like a huge space station. It would be pretty expensive if we wanted it to be super big.

We would probably also need a lot of food because there is going to be many scientists and astronauts out in space working on this project!

According to NASA, each astronaut uses about 0.83 kilograms of food per meal, including 0.12 kilograms of packaging (包装) material. Without the weight of the packaging material, we’d need about 780 kilograms of food just to feed one astronaut for a year.

Putting all these together could make it possible to make our own planet one day! In fact, creating a new planet would probably require a very modern technology and there would be tons of other things to think about. And if this is possible, it won’t likely happen within a very long time.

1. To create a new planet, which of the following should we first do?

A．To collect materials similar to Earth.	B．To prepare plenty of food for astronauts to eat.
C．To design its inner structure.	D．To find a proper place to set it.

2. How much food will an astronaut really eat for each meal?

A．About 0.12 kilograms.	B．About 0.71 kilograms.
C．About 0.83 kilograms.	D．About 0.95 kilograms.

3. What does the author think of making a new planet?

A．It is a waste of time and money.

B．It may be a dangerous thing for humans.

C．It is impossible to come true in the near future.

D．It should be one of NASA’s next plans.
