For hundreds of years humans have dreamed of finding life on distant planets.Now the hope of discovering real evidence of life has greatly increased.
NASA's Mars detector（探測器）,Opportunity,succeeded in finding signs that water once existed on the planet.Opportunity landed on Mars in January.Scientists now believe that the planet could once have supported life.
This discovery was chosen by ?Science?,one of the world's leading magazines,as the most important scientific achievement of 2004 last Friday.
“This little,wheeled,one-armed box went around another planet and has done something no human has ever managed,” according to ?Science?.“It has discovered another place in the universe where life could once have existed.
“Although we still can't say that life could have existed in this environment,it is now certain that there was water on Mars,”said Steve Squyres,one of the scientists working on the Mars mission.The evidence comes from pictures and chemical readings taken by Opportunity.It includes marks on rocks like those caused by following water on Earth and salty chemicals like those found in dried-out sea-beds.Scientists said the new evidence proved beyond doubt that water has existed on Mars.But it is still unknown whether the water was like an ocean or just ice.
While Opportunity has not found any signs of life,the presence of water means life is possible.“In everything we know about life on Earth,there is no example without liquid water,” Squyres said.“So water is important for the search for life on Mars.”
Researchers agree that a future mission（任務） should bring back physical samples（樣品）.But some scientists worry about the risk that this could introduce dangerous foreign creatures to Earth.“The problem here is how to get the samples back,”Squyres replied.“I think it is our responsibility to limit any risk.”
What proved that water existed on Mars?
A.The physical samples with salty chemicals.
B.The marks on rocks and salty chemicals.
C.Scientific achievements of 2004.
D.Creatures from Mars.
Which of the following is true according to the text?
A.It is now certain that there was water on Mars.
B.The water on Mars was like an ocean.
C.Evidence of life on Mars has been found.
D.Search for life on Mars is a great risk to humans.
How did scientists draw the conclusion that there was water on Mars?
A.The world's leading magazine has announced the fact.
B.Scientists have taken many pictures and chemical readings on the Mars.
C.Astronauts have got some rocks from Mars.
D.Scientists have made a study of the pictures and readings sent back by Mars detector.
It can be inferred that,if the creatures from Mars came to earth,_________.
A.they would be kind to humans
B.they would be cruel to humans
C.they would be a great danger to Earth
D.it would be hard to say whether it would be good news or bad news

B
The year was 1985. Ronald Reagan was president. Mikhail Gorbachev became leader of the USSR. Back to the Future was boffo at the box office. “Born in the USA” was climbing the charts. Philanthropy(慈善業(yè)) and pop culture
combined with LiveAid and “We Are the World.” And “.com”, which few people outside of the military or universities knew, came into this world.
Looking back, few could have predicted “.com” would become one of the biggest cultural touchstones of the century. In March 1985, the Information Sciences Institute at the University of Southern California assigned the first .com domain address to symbolics.com. That seemingly nominal（象征性的） event set into motion forces that would change our world forever.
.com wasn’t the birth of the Internet, but it was the budding computer network’s coming-out party. It made it pretty and inviting. It did away with the need to have complex “maps” that were the equivalent of writing a phone number on your hand, and opened it up for a mainstream audience.
After 1985, all it takes is a simple .com name to get into business. “.com” became part of our daily lexicon and drove its own economic boom and depression. It helped create a whole new family of industries, facilitated global commerce and connected people around the world in ways never before possible.
It’s now 2010. Barack Obama is president, thanks in part to his smart use of the Internet. There is no USSR. A computer-generated Avatar has set new box office records. “TiK ToK” tops the charts. We’re sending robots to find water on Mars. And that once-obscure computer communications system is one of our civilization’s most prominent features.

Sometime early in the next century, human beings will move to Mars. They will live there for about a year, and then will be replaced with another group of pioneers. Building the base on Mars will advance our knowledge of the solar system and aid in our understanding of the earth.
We already know that Mars resembles the earth in many aspects: general size, presence of water, length of day, range of temperatures. These resemblances have caused many people to consider a centuries-long project: to terraform Mars. Terraforming means altering a planet’s surface so that Earth’s life forms can survive there. This concept, previously found only in science fiction is now being seriously considered by scientists.
Terraforming Mars is theoretically simple: add nitrogen and oxygen to the atmosphere; pump water to the surface; and add the earth’s plants and animals in the order in which they developed on Earth. But it will take at least 300 years.
Some people think that such a project is too huge for humans to undertake, but there are very good reasons to make the attempt. The earth now contains some 6 billion people, and no one has any idea of how many humans the earth can support. Our very existence and numbers are threatening many other species. We also have had some experience with terraforming our own planet: altering the landscape, the atmosphere and the climate. Currently terraforming earth has become a wiser activity as we try to control global warming, air and water pollution, and preserve some natural living places.
While the possibility of such a project is small, it is not impossible .Even if earth –bound societies come and go in the next 300 years, the project can continue through the work of the Mars settlers without the need for constant backing from the earth.
The future existence of all the people in our world may very well depend upon our ability to terraform Mars.
1.What would be the best title for this passage?
A．Terraforming Mars. B．Saving the Earth
C．Travelling to Mars. D．A Newly-found Place
2.What does the underlined word “altering” mean in the second paragraph?
A．Warming. B．Changing. C．Planting. D．Building
3.According to the passage the main purpose of terraforming Mars is to ________.
A．do some scientific research work
B．find out its similarity to earth
C．a(chǎn)void the dying away of many other species
D．find on Mars living place for the increasing human beings
4.The main reason for causing many people to consider terraforming Mars is that _______.
A．there are some resemblances between Earth and Mars.
B．terraforming Mars is theoretically simple
C．we have had some experience with terraforming our own planet: Earth
D．the development of science and technology is very rapid
5.What’s the author’s attitude towards the project?
A．Optimistic. B．Negative
C．Sceptical（懷疑的） D．Objective.

September 21, 2050----At a press conference today it was announced that the first tourist heading for Mars will be the 38-year-old US businessman Patrick Clifford. He will leave the earth in the launching window of June 2052 and set his foot on the surface of Mars in November, together with the other 6 astronauts assigned for the mission to further explore the planet.
Patrick has now two years of training ahead of him to get ready for the trip. Not only will he spend five months in getting to Mars, but another 600 days there before he can go back home. Patrick was of course very excited, “ This has been my dream since I was four, and seeing the first man on Mars 20 years ago made me realize that it was possible.”
To be able to pay the $ 1. 3 billion for his ticket for the trip Patrick sold his majority stake (股份) in the company his father had built. “I know that my father would have been proud of me if he had still been alive today, he knew what this means to me”, says Patrick. There is no risk though that you will find Patrick begging in your street corner when he comes back, but it is said that he was paid twice as much for his part of the company.
So, how is he going to spend his 600 days on the red planet? “Well, since I don’t have a job when I get back after selling the company, I have plenty of time to come up with a new business idea”, he says and laughs. If he brings a shovel（鐵鍬）he can start building the first hotel there, but maybe he shouldn’t expect too many guests until someone can offer a cheaper ticket.
1.How long will Patrick Clifford be away before he comes back?
A．About five months B．About two years C．About 600 days D．About 750 days
2.The underlined part in Paragraph 3 means that .
A．the trip will turn Patrick into a beggar
B．Patrick will get much money from the trip
C．we needn’t worry about Patrick’s economic condition
D．it’s likely that Patrick will be very poor after he comes back
3.What can be inferred from the passage?
A．Patrick is an optimistic man
B．A total of six people will go to Mars
C．Patrick’s father felt excited at the news
D．Patrick will spend all his money on the trip

The US space agency NASA is looking for people to go to Mars, and stay there. This attractive career is for people who want a huge change of scenery and planet. The project is called the Hundred Years Starship, which aims to colonize (開拓殖民地) other lands such as the red planet Mars.
Settlers would travel to the red planet and live there forever. NASA says it would be too expensive to bring humans back to Earth. The space agency can afford, however, to send supplies to the astronaut pioneers from Earth. Astronauts would be landed on the planet's surface and would never be able to return home due to the cost.
NASA has started the project with $1.6 million, and hopes to attract investment from space-living billionaires. Google co-founder Larry Page told NASA he would be interested if the cost of a one-way ticket can go down from $10 billion to $2 billion.
The journey to Mars could take 4 months. Setting on the red planet would be extremely dangerous, especially given the freezing temperatures there. The thin atmosphere would be another problem as it is mostly carbon dioxide, so oxygen supplies are a must. A director in NASA said that he believed the trip might start with visiting Mars's moons first. He claimed that humans could be on Mars's moons by 2030.
Many scientists think colonizing space is absolutely necessary. Steven Hawking believes we must move to other planets to survive as a species. He said: “Once we spread out into space and establish independent colonies, our future should be safe.” Scientists Dirk' Schulze-Makuch and Paul Davies also call it a “desirable goal”, though there surely are huge risks to explore new lands.
1.Which of the following is TRUE about the Hundred Years Starship?
A．It has cost NASA around $10 billion.
B．It is expected to be conducted on Mars in 2030.
C．It aims to explore new lands in the universe.
D．It is a project first raise by Steven Hawking.
2.We can infer from the passage that Google co-founder Larry Page _______.
A．used to be an astronaut B．is no longer rich now
C．is a fan of space travel D．is a generous man
3.What would be the best title for the passage?
A．One-way trip to Mars
B．Mars's another moon is found.
C．Human landing on Mars.
D．NASA's first cooperation with Google.
