Why should mankind explore space? Why should money, time and effort be spent exploring and researching something with so few apparent benefits? Why should resources be spent on space rather than on conditions and people on Earth? These are questions that, understandably, are very often asked.
Perhaps the best answer lies in our genetic makeup as human beings. What drove our ancestors to move from the trees into the plains, and on into all possible areas and environments? The wider the spread of a species, the better its chance of survival. Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible.
Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for. Without knowledge, we may be completely destroyed by the danger. With knowledge, we can lessen its effects.
Exploration also allows minerals and other potential resources to be found. Even if we have no immediate need of them, they will perhaps be useful later. Resources may be more than physical possessions. Knowledge or techniques have been acquired through exploration. The techniques may have medical applications which can improve the length or quality of our lives. We have already benefited from other spin-offs including improvements in earthquake prediction, in satellites for weather forecasting and in communications systems. Even non-stick pans and mirrored sunglasses are by-products of technological developments in the space industry!
While many resources are spent on what seems a small return, the exploration of space allows creative, brave and intelligent members of our species to focus on what may serve to save us. While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers.The danger exists, but knowledge can help human being to survive. Without the ability to reach out across space, the chance to save ourselves might not exist.
While Earth is the only planet known to support life, surely the adaptive ability of humans would allow us to live on other planets. It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future.
1.Why does the author mention the questions in Paragraph1?

高二英语单项填空简单题查看答案及解析
China was a latecomer to space exploration, and in the movies, it has been a latecomer to science fiction, too. That is about to change. The country's first blockbuster (大片)set in space, The Wandering Earth, opens Tuesday with great expectations that it will represent the dawning of a new age in Chinese filmmaking. The film also opens with the Lunar New Year, the beginning of an official,weeklong holiday that is traditionally a peak box-office period in China. It has a limited show in the United States, Canada,Australia and New Zealand.
The Wandering Earth, shown in 3-D, takes place in a distant future in which the sun is about to expand into a red giant and destroy the Earth. The approaching danger forces the world’s engineers to make a plan to move the planet to a new solar system using giant thrusters (推进器).Things go very badly when the Earth has to pass the Jupiter, setting off desperate disturbance to save humanity from ruin.
The film comes as China reached a milestone(里程碑)in space : the landing of a probe (探测器)on the far side of the moon in January. Although decades behind Russia and the United States, China has now put astronauts in orbit and has ambitious plans to join or even lead a new age of space exploration.
''I think there is a very close connection between Chinese cinema and the nation's fortunes,'' said Sha Dan, a leader at the China Film Archive, ''When we have the ability to rescue our people abroad, we can make movies like Operation Red Sea. Only when China can enter the space age can we make works like The Wandering Earth. ''
The Wandering Earth takes for granted China's central role in future space exploration,but it also has a vision of the international teamwork necessary to deal with the threats facing the planet, a theme that runs deeply through the film.
1.What does the author think of The Wandering Earth?
A.It is a success in science-fiction films.
B.It is a hit in the oversea film markets.
C.It is the beginning of Chinese filmmaking.
D.It is only a present for the Lunar New Year.
2.What causes the Earth to wander in space?
A.A new solar system.
B.A new planet like the Earth.
C.The expanding sun in a distant future.
D.A deadly disease for people on the Earth.
3.What is reflected throughout The Wandering Earth?
A.The importance of heroes.
B.The threats from explorations.
C.The nation's power of China.
D.The international cooperation.
