The plan: turn Mars into a blue world with streams and green fields, and then fill it with creatures (生物) from the earth. This idea may sound like something from a science fiction (科幻小说), but it is actually being taken seriously by many researchers.
This suggested future for the “red planet” will be the main topic for discussion at an international conference hosted by NASA (美国宇航局) this week. Leading researchers as well as science fiction writers will attend the event. It comes as NASA is preparing a multi?billion?dollar Mars research programme. “Turning Mars into a little earth has long been a topic in science fiction,”said Dr Michael Meyer, NASA’s senior scientist for astrobiology (太空生物学). “Now, with scientists exploring the reality, we can ask what are the real possibilities of changing Mars.”
Most scientists agree that Mars could be turned into a little earth, although much time and money would be needed to achieve this goal.
But many experts are shocked by the idea. “We are destroying our own world at an unbelievable speed and now we are talking about ruining another planet,” said Paul Murdin, of the Institute of Astronomy, Cambridge, UK. Over the past months, scientists have become increasingly confident they will find Martian life forms. Europe and America’s robot explorers have found proof that water, mixed with soil, exists in large amounts on the planet.
In addition, two different groups of scientists announced on March 28 that they had found signs of methane (甲烷) in the Martian atmosphere (大气). The gas is a waste product of living creatures and could be produced by microbes (微生物) living in the red planet’s soil.
But scientists such as Dr Lisa Pratt, a biologist at Indiana University, say that these microbes will be put in danger by the little earth project. “Before we have even discovered if there is life on Mars, we are talking about carrying out projects that would destroy all these native lifeforms, all the strange microbes that we hope to find buried in the soil,” said Dr Pratt. This view is shared by Monica Grady, a planetary scientist at the Natural History Museum, London. “We cannot risk starting a global experiment that would wipe out the precious information we are looking for.” she said, “This is just wrong.”
5. The passage is about________.
A. a plan turning Mars into a little earth
B. the necessity of changing Mars
C. Mars supporting life
D. finding water in the Mars
6. Which of the following is NOT the reason why some scientists are against the plan?
A. The project would wipe out all the native lifeforms on the Mars.
B. The project will cost too much money and work.
C. We would ruin Mars.
D. We are destroying our own world at an unbelievable speed.
7. We can infer from the passage that________.
A. water is a crucial factor for life
B. the project will have little effect on the native lifeforms supposed to live on the Mars
C. Monica Grady is in favour of carrying out the little earth project
D. the idea turning Mars into a little earth is nothing but a science fiction
8. Which of the following supports the conclusion of microbes living in the Mars’s soil?
A. Scientists found liquid water in the Mars.
B. Scientists found signs of methane in the Martian atmosphere.
C. Scientists found a lot of good soil on the Mars.
D. Scientists found some creatures living on the Mars.

The world is not coming to an end on December 21, 2012, the US space agency insisted on Monday in a rare campaign to dispel widespread rumors fueled by the Internet and a new Hollywood movie.
The latest big screen offering from Sony Picture, 2012, arrives in theaters on Friday, with a 200-million-dollar production about the end of the world supposedly based on myths (虚构的故事) backed by the Mayan calendar. It is claimed that the end of time will come as a Planet X—or Nibiru—heads toward or collides with the Earth.
Some websites accuse NASA of hiding the truth on the planet’ s existence, but the US space agency denounced such stories as an “Internet hoax(恶作剧) ”. “There is no factual basis for these claims,” NASA said in a question-and-answer posting on its website. “If such a collision were real, astronomers would have been tracking it for at least the past decade, and it would be visible by now to the naked eye. Obviously, it does not exist. Credible scientists worldwide know of no threat associated with 2012,” it insisted. “After all, our planet has been getting along just well for more than four billion years.” added NASA.
There is another planet, Eris, floating in space. But the small planet similar to Pluto will remain safely fixed in the outer solar system and it can come no closer than four billion miles to the Earth, according to NASA.
Initial theories set the disaster for May 2003, but when nothing happened the date was moved forward to the winter in 2012 to coincide with the end of a cycle of the ancient Mayan calendar.
NASA insisted the Mayan calendar in fact does not end on December 21, 2012, as another period begins immediately afterward. And even if the planets were to line up as some have forecast, the effect on our planet would be “negligible”, NASA said.
“And while comets and asteroids (小行星) have always hit the Earth, big hits are very rare, ” NASA noted. The last major impact was believed to be 65 million years ago, resulting in the end of dinosaurs.
“We have already determined that there are no threatening asteroids as large as the one that killed the dinosaurs,” the space agency said.
61._______ played a key role in the spread of the rumors.
A. A new book B. The Internet and a new Hollywood movie
C. NASA D. An Indian calendar
62.The film 2012 is _______.
A. about the end of the world B. based on the scientific prediction
C. well accepted in the science field D. about a romantic love story
63.We can infer that _______.
A. people didn’t take the rumors seriously
B. Planet X—or Nibiru does exist
C. astronomers have been tracking Planet X for over ten years
D. the rumors caused a panic among some people
64.NASA thinks that Eris _______.
A. might pose a threat to the Earth B. doesn’t pose any threat to the Earth
C. is too far away to be visible D. is similar to our planet, where life might exist
65. Which of the following is the best title?
A. New Hollywood movie 2012 B. December 21, 2012, NOT the end of the world
C. End of the ancient Mayan calendar D. How rumors came into being
