Satellites go up,die in space,and stay there for a long time.They become junk that might crash into other objects,making more metal pieces.And at the speed of about 20 thousand kilometres an hour,even a tiny piece could cause significant damage.
Dr.Moriba Jah has been working on sounding the alarm.Guided by traditional ecological knowledge,he’s exploring a new path for responsible space exploration.
From a young age,he decided to find a way to serve people.Maybe he’d help find the cure for AIDS.He considered it at the time.The dream agreed with his love for biology,but instead,he was enlisted in the army for four years,where the night experience in nature introduced him to satellites and turned his attention toward space.
Now,Jah is a professor at the University of Texas at Austin.As a space environmentalist and scientist,Jah is working on solutions to the junk in the space—a problem growing more quickly than ever since the late 1990s,with the development in commercial space exploration launching rockets more often than ever.Later,he mapped the human-made objects in the Earth’s orbit (轨道) and helped launch a satellite and space junk tracker application available to the public.
About millions of space pieces are in the Earth’s orbit,and some of which are large enough to be tracked.
“The best solution is to transport it to the Earth and have it burnt up in the atmosphere,” Jah highlights,but it pollutes the atmosphere in the process.
Despite the junk in the space is growing, Jah is optimistic about the way forward.“Mother Nature is very resilient (有弹性的).We can see evidence of that,” he says.

Scientists have for the first time discovered a cave on the Moon.It could be an ideal place for humans to build a permanent base,they said.It is just one in probably hundreds of caves hidden in an “underground,undiscovered world”,according to the researchers.
Countries are racing to establish a permanent human base on the Moon,but they need to protect astronauts from radiation,extreme temperatures,and space weather.And the newly discovered cave looked like a good place for a base which will provide good protection for astronauts,and humans could potentially be living there in decades.
The cave has yet to be fully explored,but the researchers hope that radars,cameras or even robots could be used to map it.“We have very good images of the surface—we can see the Apollo spacecraft landing sites—but we know little about what lies below the surface.There are huge opportunities for discovery,” said a researcher.
The Moon cave might be useful to humans,but the scientists also stressed that it could help answer fundamental questions about the history of the Moon,and even our solar system.
The rocks inside the cave were not as damaged by space weather as other rocks,so they can provide an extensive geological record going back billions of years.

[D] It provides a new tourist destination.
(　　)2.What makes the Moon cave a potential site for a human base
[A] Its temperature.
[B] Its length.
[C] Its protection.
[D] Its width.
(　　)3.What can be inferred about the exploration of the Moon cave
[A] It is affected by lack of funding.
[B] It holds great potential for scientific discovery.
[C] It has been completed using advanced technology.
[D] It is focused on finding evidence of life on the Moon.
(　　)4.What is the scientists’ attitude towards the Moon cave

New invention to get astronauts moving in space
NASA says that astronauts can lose as much as 10% of their bone density (骨密度) when they’re in space.That’s because there is no gravity for their bodies to push against.1.　　　 It is a machine that allows them to jump in zero gravity.
Jumping in zero gravity would help build up bone density and muscle mass rather than astronauts losing this while in space.2.　　　　This is to maintain a healthy lifestyle and prevent them from losing too much muscle and bone density.An engineer of this project,says that his machine would cut workout time down to just six minutes a day!It will allow astronauts to take part in a short but intense workout designed to build both muscle mass and bone density.
The engineer says that jumping is important to maintain good bone density.3.　　　So he thinks his invention is the perfect solution.
A former NASA astronaut says that exercising in space is very important for a successful recovery once back on the Earth.He says he would welcome shorter workouts to ensure other duties on the spacecraft can still be completed.4.　　　 “When you’re jumping on this you can really feel it from your toes right through your shoulders,” she says.
Experts say this machine could also save much-needed space on board.5.　　　　And it’s expected that it will join some astronauts in space in recent years!
A.However,jumping in zero gravity is really hard.
B.Now,astronauts don’t spend much time exercising.
C.Next year the machine will be tested in zero gravity.
D.Some people wonder whether the machine will work in space.
E.At the moment astronauts spend up to two hours a day,six days a week exercising.
F.An engineer from London has found the solution to keeping astronauts fit and healthy in space.
G.Tess Morris-Paterson,who has been testing the machine,says the workout gives her full-body benefits.

If you look up at the sky on a clear and dark night,you’ll see more stars than your eyes can count.Most of these stars have planets,similar to our own,orbiting them.With so many celestial bodies floating out in space,you can’t help but question whether other forms of life exist in the universe.And if that’s the case,is it possible to contact them
Science is still somewhat divided on this issue.Currently,no evidence exists to suggest that intelligent life exists elsewhere in the universe.Yet with an estimated one trillion planets in our galaxy alone,it seems highly likely that Earthlings aren’t the only intelligent creatures out there.Some claim that life can only develop under perfect circumstances,and the Earth is perhaps the only example of this.Other scientists object to this claim,and point out that even on the Earth,life can find a way under the most extreme circumstances.
Some people believe that aliens have already visited our planet,but this information is being kept secret by governments.The most famous incident of this kind occurred in Roswell,New Mexico in 1947.On that date,many residents reported seeing an unusual flying disc streak through the sky,before it crashed in a field.When the military heard about the crash,they quickly sealed off the area.A few hours later,the army base announced that it had recovered a flying disc.Shortly after,this statement was retracted and it was said that it was a weather balloon that crashed.However,years later one local mortician even claimed that the military had him secretly perform an autopsy on a dead alien body.
Others believe that there certainly are other life forms out there,but the distance between us is too great.Even if we could somehow create a spaceship that travels at the speed of light,it would still probably take several lifetimes to reach them.Then again,we might never have to do this if aliens reach us first.

[A] Because an unusual flying disc was ever witnessed.
[B] Because life exists despite extreme conditions as those on the Earth do.
[C] Because the government’s statement seemed suspicious.
[D] Because there are a great number of planets in the universe.
【答案】 D
【解析】 细节理解题。根据第二段中“Yet with an estimated...the only intelligent creatures out there.”可知,有些科学家认为其他星球上有生命是因为宇宙中有大量的行星。故选D。
(　　)2.What does the underlined word “retracted” in Paragraph 3 mean
[A] Examined again to guarantee the correctness.
[B] Emphasized again to persuade people.
[C] Formally took back what had been said.
[D] Seriously criticized due to poor evidence.
【答案】 C
【解析】 猜测词义题。根据画线词上文“A few hours later,the army...statement was”以及下文“it was said that it was a weather balloon that crashed”可知,该军事基地宣布他们发现了一个飞碟。不久之后,这一声明被撤回。据说此“飞碟”是一个坠毁的气象气球。故画线词意思是“正式收回说过的话”。故选C。

Satellites go up,die in space,and stay there for a long time.They become junk that might crash into other objects,making more metal pieces.And at the speed of about 20 thousand kilometres an hour,even a tiny piece could cause significant damage.
Dr.Moriba Jah has been working on sounding the alarm.Guided by traditional ecological knowledge,he’s exploring a new path for responsible space exploration.
From a young age,he decided to find a way to serve people.Maybe he’d help find the cure for AIDS.He considered it at the time.The dream agreed with his love for biology,but instead,he was enlisted in the army for four years,where the night experience in nature introduced him to satellites and turned his attention toward space.
Now,Jah is a professor at the University of Texas at Austin.As a space environmentalist and scientist,Jah is working on solutions to the junk in the space—a problem growing more quickly than ever since the late 1990s,with the development in commercial space exploration launching rockets more often than ever.Later,he mapped the human-made objects in the Earth’s orbit (轨道) and helped launch a satellite and space junk tracker application available to the public.
About millions of space pieces are in the Earth’s orbit,and some of which are large enough to be tracked.
“The best solution is to transport it to the Earth and have it burnt up in the atmosphere,” Jah highlights,but it pollutes the atmosphere in the process.
Despite the junk in the space is growing, Jah is optimistic about the way forward.“Mother Nature is very resilient (有弹性的).We can see evidence of that,” he says.
【语篇导读】 本文是说明文。文章主要介绍了科学家Moriba Jah博士为解决太空垃圾问题所做的研究和努力并向读者普及了太空环保的知识。

Scientists have for the first time discovered a cave on the Moon.It could be an ideal place for humans to build a permanent base,they said.It is just one in probably hundreds of caves hidden in an “underground,undiscovered world”,according to the researchers.
Countries are racing to establish a permanent human base on the Moon,but they need to protect astronauts from radiation,extreme temperatures,and space weather.And the newly discovered cave looked like a good place for a base which will provide good protection for astronauts,and humans could potentially be living there in decades.
The cave has yet to be fully explored,but the researchers hope that radars,cameras or even robots could be used to map it.“We have very good images of the surface—we can see the Apollo spacecraft landing sites—but we know little about what lies below the surface.There are huge opportunities for discovery,” said a researcher.
The Moon cave might be useful to humans,but the scientists also stressed that it could help answer fundamental questions about the history of the Moon,and even our solar system.
The rocks inside the cave were not as damaged by space weather as other rocks,so they can provide an extensive geological record going back billions of years.
