一、阅读理解
Passage 1
The concept of space tourism,once confined to science fiction,is rapidly becoming a reality.In the past
few years,private companies such as SpaceX,Blue Origin,and Virgin Galactic have made significant
strides in developing reusable rockets and spacecraft capable of carying civilians beyond Earth's
atmosphere.While the cost remains prohibitively high-tickets range from $250,000 to tens of millions-
the number of wealthy individuals willing to pay for a brief experience of weightlessness is growing
However,the environmental impact of frequent rocket launches is a growing concem.A single launch of
a large rocket can emit hundreds of tons of carbon dioxide and other pollutants into the upper atmosphere
Scientists warn that the accumulation of soot and particulate matter could affect cloud formation and even
contibute to global warming.For example,a 2022 study published in Earth's Future estimated that the
global space industry's carbon footprint could increase by a factor of 10 by 2030 if no regulations are
implemented.
Proponents argue that space tourism could fund further technological innovations,such as more efficient
propulsion systems and cleaner fuels.They also point to the potential for spin-off technologies that could
benefit Earth,like water recycling systems and advanced materials.Nevertheless,critics call for sticter
environmental standards before the industry expands further.Some propose a"space carbon tax"to offset
emissions,while others advocate for bans on suborbital flights that serve no scientific purpose.
As the debate continues,one thing is clear:the dream of ordinary people traveling to space is no longer
absurd.The question is whether we can manage the costs-both financial and environmental-before it
becomes widespread.
()1.What is the main topic of the passage?
A.The history ofspace exploration.
B.The environmental challenges of space tourism
C.The advantages of reusable rockets.
D.The future of interplanetary travel.
()2.According to the passage,one negative aspect of space tourism is that
A.it is only available to the rich
B.it causes pollution in the upper atmosphere
C.it has no scientific value
D.it makes space exploration less important
()3.What did the 2022 study predict?
A.The space industry will become carbon-neutral by 2030
B.The carbon footprint of space industry may increase ten times by 2030
C.Rocket launches will be banned after 2030
D.Private companies will dominate space tourism by 2030.
()4.Which of the following measures do critics suggest?
A.Encouraging more suborbital flights
B.Reducing the cost of space tickets.
C.Imposing a carbon tax on space activities.
D.Developing new space stations.
()5.What is the author's attitude toward space tourism?
A.Strongly supportive.
B.Completely opposed.
C.Objective yet cautious.
D.Indifferent.
Passage 2
When astronauts live aboard the International Space Station (ISS),they face unique physiological
challenges that scientists are only beginning to fully understand.Among the most serious is bone density
loss.In microgravity,bones that normally bear weight on Earth-such as those in the legs and spine-
begin to weaken at a rate of about 1%per month.Without countermeasures,an astronaut on a six-month
mission could lose up to 6%of bone mass,increasing the risk of fractures.
To combat this,astronauts follow a strict exercise regimen.They spend about two hours each day using
specialized equipment like the Advanced Resistive Exercise Device (ARED),which uses vacuum
cylinders to simulate weightlifting.Treadmills and stationary bicycles with hamess systems also help
maintain cardiovascular fitness.However,even with intense exercise,bone loss is not entirely prevented.
Researchers have found that the bone mineral density of long-duration astronauts often does not fully
recover even after returning to Earth.
Another major issue is the effect of cosmic radiation.Unlike on Earth,where the atmosphere and
magnetic field provide protection,astronauts in space are exposed to higher levels ofionizing radiation.
This can damage DNA,increase the risk of cancer,and affect cognitive function.NASA is studying the
use of shielding materials,such as water or polyethylene,and investigating pharmaceutical
countermeasures.
The psychological toll is also significant.Confinement,isolation,and separation from family can lead to
mood swings,depression,and anxiety.Crew members on the ISS undergo regular psychological
evaluations and maintain contact with loved ones via video calls.Some future missions,such as a tip to
Mars,which could take over a year each way,will require even more robust mental health support.
Understanding these risks is not only crucial for the safety of astronauts but also for future plans oflong-
term space habitation and colonization.As we venture deeper into space,the human body will remain the
most critical-and perhaps the most fragile-component of any mission
()1.What does the passage mainly discuss?
A.The equipment used on the ISS.
B.The physical and mental health risks faced by astronauts.
C.The benefits of space travel for human health.
D.The history of the ISS construction.
()2.How much bone mass might an astronaut lose during a half-year mission?

D.12%
()3.What measure is mentioned to counter bone loss?

()4.Why does the passage mention water or polyethylene?
A.To compare different materials for spacecraft construction

C.To explain how astronauts get drinking water in space.
D.To show the cost of space equipment.
()5.What can be inferred about a potential Mars mission?
A.It will be easier than ISS missions
B.It will require better mental health support.
C.It will cause no bone loss.
D.It will last only a few months

三、阅读短文回答问题
Space exploration has brought about countless technological spin-offs that we now take for granted.One
of the most famous examples is GPS (Global Positioning System).Originally developed by the U.S
Department of Defense for military navigation,GPS relies on a network of satellites orbiting Earth.
Today,it is used in smartphones,cars,and even farming equipment
Another innovation is memory foam.This material was invented by NASA in the 1960s to improve seat
cushioning and crash protection for astronauts.Now it is widely used in mattresses,pillows,and hospital
beds,providing comfort and support.
Water purification systems developed for space missions have also had a huge impact on Earth.The need
to recycle water on the International Space Station led to advanced filtration technologies that are now
used to provide clean drinking water in remote areas and disaster-stricken regions.
Even the humble ear thermometer owes its existence to space research.NASA invented infrared
thermometers to measure the temperature of stars and planets.Later,this technology was adapted to create
the instant-read ear thermometers used in hospitals and homes today
These examples show that the benefits of space exploration extend far beyond scientific knowledge.They
improve our quality of life and solve real-world problems.As we continue to explore the cosmos,we can
expect even more surprising inventions that will shape our future.
1.What is the main idea of the passage?
2.How does GPS originally relate to space exploration?
3.What was memory foam originally developed for?
4.Why are water purification systems mentioned in the passage?
5.What does the author imply about future space exploration?

In my opinion,it is worthwhile to invest in space exploration.First,space research leads to technological
advances that benefit our everyday life,such as GPS,satellite communication,and medical devices.
These innovations improve the quality of life for millions.Second,space exploration helps us better
understand our planet and the universe.For example,studying other planets can provide insights into
climate change and the origins of life.Although some argue that the money could be used to solve
problems on Earth,I believe that space exploration is not a luxury but an investment in our future.It
inspires young people to pursue science and pushes the boundaries of human achievement.Therefore,we
should continue to support space exploration wisely.
