3．In 1969，when Neil Armstrong first landed on the Moon，many people thought soon we would be regularly visiting other planets.（1）
The reality is that space exploration is extremely difficult and dangerous.Some people believe it is a waste of the public purse and does nothing to improve our lives.Why do we continue to explore space，then？
（2）From the very early days of human life on the Earth，our curiosity about the unknown has kept us adventuring into new places.While space exploration is a reality，we remain curious about the mysteries of the universe.With each space mission comes greater insight，thus motivating us to continue along the same path of adventure.
With technologies developed for space exploration，we can solve some big problems facing mankind，making our lives safer and easier.（3）Originally applied to the space shuttle launch，they have also been set up in the cities with a high frequency of earthquakes to protect buildings and save lives.
Although space exploration demands huge investment，it can actually bring great economic value.The global space economy is increasing by billions of dollars every year.（4）Jobs in the space industry go far beyond the astronauts.There are many support staff on the ground，such as engineers and research assistants.
Moreover，the amazing work can provide education and inspiration for the next generation.Such wonders as a space shuttle launch or astronauts walking on the Moon are incredibly inspiring to witness.These moments shape children's lives forever and motivate them to become the scientists and engineers of the future.（5）
A.This is clearly not the case.
B.It is in our nature to explore.
C.The universe is too mysterious to explore.
D.One of these is earthquake shock absorbers.
E.It can also provide a variety of career opportunities.
F.These scientific and technological advances can benefit societies in many areas.
