NASA’s Mars detector (探測(cè)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 flowing 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 on Mars 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(wù)) 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.”
【小題1】________ prove 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
【小題2】Which of the following is TURE 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.
【小題3】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.
【小題4】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 a good news or bad new

Technology: Taking the good without the bad?
Very soon, unimaginably powerful technologies will remake our lives．This could have dangerous consequences, especially because we may not even understand the basic science underlyi ng them．There’s a growing gap between our technological capability and our basic scientific understanding．We can do very clever things with the technology of the future without necessarily understanding some of the science underneath, and that is very dangerous．
The technologies that are particularly dangerous over the next hundred years are nanotechnology （納米技術(shù)）, artificial intelligence and biotechnology．The benefits that they will bring are beyond doubt．But they are going to be very, very dangerous．I’m working in the field of artificial intelligence．I have a model design for something that might be 50,000 million times smarter than the human brain．Target date is 2010．The only thing that's not possible in the film Terminator（終結(jié)者） is that the people win．If you're fighting against technology w hich is 50,000 million times smarter than you, you probably will not win．
Nanotechnology．We've all heard of the grey glue problem, that self-replicating nanotech devices might keep on copying until the world has become sticky glue．And certainly in biotechnology, we've really got a big problem because it's converging with nanotechnology and IT．Once you start mixing nanotech with organisms and you start feeding nanotech-enabled bacteria, we can really go an awful lot further than the Borg in Star Trek（星際迷航）．And those superhuman organisms might not like us very much．
Eventually these technologies will become routine．That’s a threat to humanity．I don’t think it’s possible to slow it down．So what we need to do is accelerate the scientific research and try to get some extra tools．The problems facing us in the future are getting bigger and bigger．I think if we don’t get some proper science done, the future is hopeless indeed．
【小題1】From the text, we know that the author’s greatest concern is         ．

A．our lack of technological understanding of the process involved
B．our lack of technological capability
C．creating technology without really understanding the basic science
D．Our refusal to face the consequences of the technology we create
【小題2】It can be inferred from the text that the author         ．
A．thinks people overvalue the capabilities of technology
B．is not optimistic that artificial intelligence will always be used positively
C．thinks that we should take science fiction movies more seriously
D．believes artificial intelligence is the greatest threat we face technologically
【小題3】Why does the author say it is not possible in the film Terminator that the humans win?
A．Because the power of the technology is exaggerated（夸大）．
B．Because the strength of the machines is much greater．
C．Because machines with that much intelligence can easily defeat humans．
D．Because human beings are not courageous enough to win the battle．

科目：高中英語(yǔ) 來(lái)源：2014屆四川省高二下學(xué)期期中考試英語(yǔ)試卷（解析版） 題型：閱讀理解

Holidaymakers who are bored with baking beaches and overheated hotel rooms head for a big igloo. Swedish businessman Nile Bergqvist is delighted with his new hotel, the world’s first igloo hotel. Built in a small town in Lapland, it has been attracting lots of visitors, but soon the fun will be over.

In two weeks’ time Bergqvist’s ice creation(作品) will be nothing more than a pool of water. “We don’t see it as a big problem,” he says. “We just look forward to replacing it.”

Bergqvist built his first igloo in 1991 for an art exhibition. It was so successful that he designed the present one, which measures roughly 200 square meters. Six workmen spent more than eight weeks piling 1,000 tons of snow onto a wooden base; when the snow froze, the base was removed. “The only wooden thing we have left in the igloo is the front door,” he says.

After their stay, all visitors receive a survival certificate recording their success. With no windows, nowhere to hang clothes and temperatures below 0℃, it may seem more like a survival test than a relaxing(輕松的) hotel break. “It’s great fun,” Bergqvist explains, “As well as a good start in survival training.”

The popularity of the igloo is beyond doubt: it is now attracting tourists from all over the world. At least 800 people have stayed at the igloo this season even though there are only 10 rooms. “You can get a lot of people in,” explains Bergqvist. “The beds are three meters wide by two meters long, and can fit at least four at one time.”

1. Bergqvist designed and built the world’s first igloo hotel because ________.

A．a(chǎn)n art exhibition was about to open

B．he wanted to make a name for the small town

C．he believed people would enjoy trying something new

D．more hotel rooms were needed

2. When the writer says “the fun will be over,” he refers to the fact that ________.

A．hotel guests will be frightened at the thought of the hard test

B．a(chǎn) bigger igloo will replace the present one

C．holidaymakers will soon get tired of the big igloo

D．Bergqvist’s hotel will soon become a pool of water

3.According to the text, the first thing to do in building an igloo is ________.

A．to gather a pool of water

B．to prepare a wooden base

C．to cover the ground with ice

D．to pile a large amount of snow

4. When guests leave the igloo hotel they will receive a paper stating that ________.

A．they have had a taste of adventure

B．they have had an ice-snow holiday

C．they have had great fun sleeping on ice

D．they have visited Lapland

5.Which of the following pictures below is closest to the igloo hotel as described in the text?
