Life on Mars could become a reality and it could happen in your lifetime.
A welcoming planet
Scientists say Earth’s neighbor Mars, a bright red planet about half Earth’s size, is the most likely to support human life. Mars even has frozen water on its surface.
Since the late 1990s, NASA has been exploring Mars using remote-controlled vehicles(装置). Most recently Curiosity, a car-size vehicle, traveled through space on an unpiloted spacecraft(航天器) and landed on Mars in August 2012. Directed by NASA scientists , the vehicles move on the surface, taking pictures , collecting and analyzing soil, and looking for signs of life.
But what about human explorers? Plans are already in the works to send astronauts to Mars as soon as the mid-2030s.
_____________________________________
But before you start packing your bags, let’s consider the challenges. For starters, Mars is far away. Just getting there could take up to 10 months.
Scientists already know that time away from Earth’s gravity harms the human body. Bones and muscles get weaker. The body produces less blood. What damage would months and months of living in space do?
And then there is the matter of water, oxygen, food and fuel. Scientists will have to find solutions to these problems, or the first humans on Mars won’t survive very long in their new home.
Tiny Dangers
There’s another tinier risk. It’s so tiny that you can’t even see it: germs.
Some scientists believe that our germs could pollute the whole planet of Mars. Potentially killing Martian life before we have the chance to discover it. Worse, there is a small but terrifying chance that any microscopic life already there might be harmful to us .
Worse still, if any of those Martian germs(火星细菌) were brought back to Earth, the result could be disastrous. Animals, plants, and people could be wiped out.
Worth the $$$?
A more practical concern is the cost. The price could approach $ 1 trillion(万亿). How can we justify spending that much when so many problems—poverty, disease—could use the cash here on Earth?
1.Which of the following is TRUE according to the “A welcoming planet” part?
A. Mars is a little bigger than Earth.
B. There are flowing rivers on Mars.
C. People haven’t been to Mars so far.
D. Scientists have discovered signs of life on Mars.
2.Which of the following can best fill in the blank in the passage?
A. Living in space. B. Limited resources.
C. Extreme conditions. D. Interesting challenges.
3.By “Tiny dangers” the author means ________________.
A. there is no serious danger
B. people won’t be in any danger
C. it’s difficult for people to realize the danger
D. the danger may be caused by very small things
4.Which may cause the biggest danger?
A. Martian germs may be different from those on Earth.
B. Martian germs may be brought back to Earth.
C. People may carry germs to Mars.
D. There may be germs on Mars.
5.Which section of a newspaper is the passage most probably taken from?
A. People B. History C. Science D. Business

I love science and science fiction. Like many science fiction fans, I am fascinated by the possibility of time travel. However, one must combine romance with reasoning and look into the chances of time travel critically.
First of all, we must remember the whole universe is in motion. If we want to go back to yesterday, our "time machine" has to move back in time and space. If someone claimed he was at home when he suddenly travelled 200 years back in time, he either had an illusion or made the story up. Two hundred years ago, Earth was in a different place in space, so how can you travel back 200 years without moving in space? Don't get me wrong. I am not knocking the genius of science fiction writers. H.G. Wells's "The Time Machine" is a great work of fiction, but that’s all. I have read many other time travelling science fiction stories since reading H.G. Wells, but none address this problem of displacement.
My own argument for the impossibility of time travel is that physical states of the past no longer exist and those of the future are not here yet. To be able to move back and forth in time requires everything that has happened, is happening, and will happen everywhere in the whole universe at every single moment in time-past, present, and future-to be stored as a "reality" somewhere-like the save game file of a computer game that contains every single byte of information of the game at the point it was saved, but you would need an almost extremely large file and almost extremely many of them-so it can be re-entered and communicated with, and not just light signals for viewing. To me, I don’t buy it.
1.Which of the following can be the best title?
A. How to make time travel possible?
B. Why am I fascinated by time travel?
C. Why do I think time travel is not possible?
D. How to explain the possibility of time travel?
2.What’s the meaning of the underlined word “illusion”?
A. success B. dream C. switch D. support
3. According to the author, which of the following is RIGHT?
A. We can go back to the past by time travel.
B. People can travel to the future by moving in space.
C. “The Time Machine” is nothing more than a science fiction.
D. Everything that happened, is happening and will happen can be stored somewhere.
4.In the author’s opinion, time travel might be possible if .
A. people could combine romance with reasoning
B. people could stop the movement of the whole universe
C. people could use time machine under the instruction of H.G. Wells
D. people could “save” everything in the past, present and future in a certain space
