After a shaky start, the Martian flotilla that has arrived over the past few weeks is getting down to business. Two of the five craft in it seem to be working perfectly. Two are lost. And a fifth is sick, but undergoing treatment.
The most spectacular pictures so far have been provided by Mars Express, the European Space Agency's contribution to the fleet. On January 28th this reached its final working orbit (which takes it over both poles, and thus allows it to see the whole of Mars over the course of a few days as the planet revolves beneath it). It has, however, been sending back data since shortly after it arrived, and a few days ago its controllers released a series of beautiful photographs, including a stereo image of Valles Marineris, a huge canyon that may have been formed by flowing water.
The most scientifically significant result, though, has come from Opportunity, America's second Mars rover. One of Opportunity's cameras has photographed evidence of stratification in nearby rocks. Such stratification indicates that the rocks concerned are sedimentary. The layers could be repeated wind-blown deposits, or consist of ash from successive volcanic eruptions. But the terrestrial rocks they most resemble are ones that have formed under water.
The reason everyone is getting so excited is because there is a widespread assumption that any form. of life which might dwell on Mars would need liquid water to live—or, even if it could now subsist by extracting moisture from ice, would have needed liquid water to evolve to that stage. Mars has seen more probes launched towards it than all of the other planets put together precisely because of this hope that it might harbour life. So there is a lot riding on the answer—not least the funding of future missions.
Besides its scientific significance, the success of Opportunity has also helped to distract attention from the sudden refusal of Spirit, the first American rover to arrive on Mars, to talk to its controllers. This craft had tentatively, but successfully, nosed its way off its landing platform, and was about to drill its way into a nearby rock prior to doing a spot of chemical analysis, when it went silent.
However, the engineers at NASA, America's space agency, are nothing if not resourceful, and they have a good record of carrying out running repairs on spacecraft that are millions of kilometres away. In the case of Spirit, they think that one of the craft's memory chips has got cluttered up with files created on the journey to Mars. That caused another chip, which manages the first, to throw a wobbly and to keep rebooting the computer. They are currently testing this idea by loading a diagnostic program on to the computer. In addition, as a precaution, they have deleted excess files from the equivalent memory chip on Opportunity.
Spirit's spirits may thus revive. As to the failures, the Japanese abandoned their fly-by craft Nozomi in December, and the British team in charge of Beagle 2, which is presumed to have landed on December 25th but from which no signal has been received, also seems to have called it quits. Still, a 40460% success rate (depending on whether Spirit is brought back into commission) is not bad by the historical standards of missions to Mars. Now, the real science begins.
Mars Express is mentioned because______.
A．it has been sending data back to the Earth
B．it illustrates Europe's contribution to the project
C．it is the first craft to have ever landed on the Mars
D．it can help researchers see the whole of the Mars

That cold January night, I was growing sick of my life in San Francisco. There I was, walking home at one in the morning after a tiring practice at the theater. With opening night only a week
away, I was still learning my lines. I was having trouble dealing with my part-time job at the bank and my acting at night at the same time. As I walked, I thought seriously about giving up both acting and San Francisco. City life had become too much for me.
As I walked down empty streets under tall buildings, I felt very small and cold. I began running, both to keep warm and to keep away from any possible robbers (抢劫犯). Very few people were still out except a few sad-looking homeless people under blankets.
About a block from my apartment (公寓房间), I heard a sound behind me: I turned quickly, half expecting to see someone with a knife or a gun. The street was empty. All I saw was a shining streetlight. Still, the noise had made me nervous, so I started to run faster. Not until I reached my apartment building and unlocked the door did I realize what the noise had been. It had been my wallet falling to the sidewalk.
Suddenly I wasn't cold or tired anymore. I ran out of the door and back to where I'd heard the noise. Although I searched the sidewalk anxiously for fifteen minutes, my wallet was nowhere to be found.
Just as I was about to give up the search, I heard the garbage truck (垃圾车) pull up to the sidewalk next to me. When a voice called from the inside, "Lily Smith？" I thought I was dreaming. How could this man know my name？ The door opened, and out jumped a small red-haired man with an aroused look in his eyes. "Is this what you're looking for？" he asked, holding up a small square shape.
It was nearly 3 a.m. by the time I got into bed. I wouldn't get much sleep that night, but I had gotten my wallet back. I also had gotten back some enjoyment of city life. I realized that the city couldn't be a bad place as long as people were willing to help each other.
How did the writer feel when she was walking home after work？
A．Cold and sick.
B．Fortunate and hopeful.
C．Satisfied and cheerful.
D．Disappointed and helpless.

On April the 18th, 1960, it was a few minutes after 5 o'clock in the morning. Most people in San Francisco were a-sleep, but the rattling of the milkmen's carts and bottles meant that the city was waking to another busy day.
At that moment the land suddenly moved. The vibration was so strong that great buildings fell down, including the new seven-million-dollar City Hall, which the community had good reason to be proud of. Main water pipes burst. Cooking stoves overturned and electric wires flashed. The fires which started caused damage in large areas of the city.
What had happened.'？ The rocks had broken apart along nearly three hundred miles of a crack in the earth of California, a feature of the physical map of that region known as a "fault".
The damage was greatest in San Francisco which was near the center of the fault. Many buildings were destroyed by fire or by the earthquake itself, and hundreds of people were killed. Many people also died from diseases which broke out in the dirty camps later occupied by homeless people. The fires got out of control and, before they died out, four square mi-les of the city were burnt out.
The loss of property was serious. The loss from fire alone amounted to 400,000,000 dollars, more than nine-tenths of the total damage. In those days this was an enormous sum.
The effects of the earthquake were widespread. Rivers and streams began to run in new directions and their flow pat-terns were changed. Trees six feet in diameter were uprooted within half a mile of the central break. An area of wet fields on the side of a hill actually moved half a mile downwards. A road which crossed the fault burst apart and a gap of 21 feet remained between the broken ends.
The California earthquake is remembered because it was so sudden and because it occurred in a city, where the dam-age and destruction were plainly visible and where many people were killed simultaneously. Actually, deaths on American roads from car accidents are now greater in almost any week of the year, but we are so accustomed to road accidents that we do not pay much attention to them.
Scientists and engineers studied the effects of the San Francisco earthquake. The city was rebuilt, and new features were introduced to strengthen buildings and maintain a constant water supply in the event of. another earthquake. The water mains were fitted with control values which would enable water to travel by different routes round broken places. Large underground tanks were constructed to supply water if normal supplies could not be tapped. Special measures were taken to prevent fires, which often do more damage than earthquakes themselves.
The San Francisco earthquake provided scientists with valuable information, since the effects of the break were visible and reports of the incident were an important contribution to the world's store of knowledge about earthquakes.
The main cause of the great loss of property 'after the San Francisco earthquake in 1960 is______.
A．falling buildings
B．broken pipes
C．fires
D．floods

听力原文： Like hundreds before them, a team of 10 Americans arrived at the second of four base camps on Mt. Everest this week. But tike few others, this one had a goal of making history.
That' s because one of its members is 32 - year - old Erik Weihenmeyer, who hopes to become the first blind man to clear the famed 29,035 -foot peak.
Weihenmeyer has been blind since age 13, having lost his sight to a rare disease called retinoschisis. But despite his lack of sight, the Denver, Colo. , man has still managed to turn himself into a world - class adventurer -- a certified sky and scuba diver who also competes in long - distance bi king and marathon running, as well as skiing and mountain eering. In 1995, he scaled North America' s highest peak, Mt. McKinley; in 1997, he topped Mt. Kilimanjaro, and in January 1999, he summited Argentina' s Aeoneagua, the tallest mountain in South America. Weihenmeyer has climbed mountains using a system he devised himself. He works with two long adjustable trekking poles -- leaning on one and scanning in front of him with another. He' ll also use his sense of hearing, listening to footsteps around him and a hell tied to the climber ahead of him. But Weinhenmeyer says he' ll also be a real part of the team. He says he's strong, and can contribute by carrying loads, setting up tents and building up snow walls. Weihenmeyer says he wants to climb the highest peak on all seven continents -- but he says he' s no daredevil. Still, Weibenmeyer admits to sealy moments. One of the worst was on an open ridge on Mt. McKinley, where a miscalculation of a few inches could have meant death. The lessons are only part of the reason Weinhenmeyer wanted to climb Everest. He says he' s wanted to take on the mountain for a long time. The folklore surrounding the mountain, all the famous tales --" You read a bout it from such an early age. It' s cool to be part of it," he said.. There' s the bonus of feeling of the sun on your face, and sensing the height of where you are, from the sound and the space around you. That blindness is also a reason he' s climbing. He' s being supported by the National Federation for the Blind, an activist organization seeking to change the way people think about blindness. But Weihenmeyer also recognizes that a good part of his climb is for himself.
Weibenmeyer' s team will attempt to summit Everest via the southeast ridge route pioneered by Sir Edmund Hillary and Tenzing Norgay 47 years ago. The team attempted to summit the 22,486 foot Mount Ama Dablam, in the Everest region in Nepal last year, but had to withdraw because of bad weather. In May 1998, a disabled American climber, Tom Whittaeker, who has an artificial leg, climbed Everest.
Why did the team of 10 Americans had a goal of making history？
A．Because it is the first team that topped Mt. Everest.
B．Because all of the members of the team are blind men except Erik Weihenmeyer.
C．Because one of its members is Erik Weihenmeyer, who hopes to become the first blind man to clearthe famed Mt. Everest.
D．Because all of the members of the team are old men who are eager to climb the famed peak.
