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

"Equal pay for equal work" is a phrase used by the American women who feel that they are unfairly treated by society. They say it is not right for women to be paid less than men for the same work.
Some people say men have more duties than women. A married man is thought to earn money to support his family and to make the important decision, so it is right for them to be paid more. Some are even against married women working at all. When wives go out to work, they say, the home and children are given no attention to. (80) If women are encouraged by equal pay to take full-time jobs, they will be unable to do the things they are best at doing: making a nice home and bringing up children.
Women who disagree say they want to escape from the limited place which society wishes them to fill and to have freedom to choose between work and home life, or a mixture of the two. Women have the right not only to equal pay but also to equal chances.
The women use the phrase "equal pay for equal work" to ask society to _________.
A.pay men less than women
B.give Women harder work
C.pay men and women the same amount of money for the same work
D.pay people more who do harder work

听力原文: When people succeed, it is because of hard work, but luck has a lot to do with it, too. Success without some luck is almost impossible. The French emperor Napoleon said of one of his generals, "I know he's good. But is he lucky?" Napoleon knew that all the hard work and talent in the world can't make up for bad luck. However, hard work can invite good luck..
When it comes to success, luck can mean being in the right place to meet someone, or having the right skills to get a job done. It might mean turning down an offer and then having a better offer come along. Nothing can replace hard work, but working hard also means you're preparing yourself opportunity. Opportunity very often depends on luck.
How many of the great inventions and discoveries came about through a lucky mistake or a lucky chance? One of the biggest lucky mistakes in history is Columbus' so-called discovery of America. He enriched his sponsors and changed history, but he was really looking for India. However, Columbus' chance discovery wasn't pure luck. It was backed up by years of studying and calculating. He worked hard to prove his theory that the world was round.
People who work hard help make their own luck by being ready opportunity knocks. When it comes to success, hard work and luck are always hand in hand.
