听力原文： Many scientists today are convinced that life exists elsewhere in the universe. Life probably much like that on our own planet. As far as astronomers can determine, the entire universe is built of the same matter. (26) They have no reason to doubt that matter obeys the same laws in every part of the universe. Therefore, it is reasonable to guess that other stars, with their own planets, were born in the same way as our own solar system. What we know of life on earth suggests that life will arise wherever the proper conditions exist.
If we suppose that every star in the universe has a family of planets, then how many planets might support life？ (27)First, eliminate those stars that are not like our sun. Next. eliminate most of their planets; they are either too far from or too close to their suns. Then eliminate all those planets which are not the same size and weight as the earth. Finally, remember that the proper conditions do not necessarily mean that life actually does exist on a planet. It may not have begun yet, or it may have already died out.
This process of elimination seems to leave very few planets on which earthlike life might be found. However. even if life could exist on only one planet in a million, (28) there are so many billions of planets that this would still leave a vast number on which life could exist.

Any good mystery must eventually uncover a villain, and in a recent documentary, "Who Killed the Electric Car？", the filmmakers duly pointed the finger at General Motors. The【C1】______ is not so simple, but there is little doubt that when GM pulled the plug on its EV1 battery-powered car a decade ago, other【C2】______ followed the Giant carmaker's lead.
Yet GM has now 【C3】______ its enthusiasm for electric vehicles — or at least for their close cousins, hybrid cars (混合动力汽车). At the upcoming auto show, the company is expected to【C4】______ a prototype that overtakes existing hybrids，【C5】______ Toyota's Pruis.
Today's hybrids capture energy normally【C6】______ during braking and coasting and use it to power an electric motor that can provide extra bursts of【C7】______ when needed. The Pruis and other hybrids can also run【C8】______ battery power alone at low speeds over short distances, such as in stop-start traffic.
But GM's new car is expected to be a "plug-in" hybrid, which, as its name implied, can be recharged by 【C9】______ it into the mains (干线). Together with a big battery pack, this provides a much larger range in all-electric【C10】______ , after which the petrol engine kicks in. GM's car is expected to go around 50 miles (80 km) in all-electric mode，【C11】______ enough for American commuters, who would need to use the 【C12】______ engine on longer trips only. The【C13】______ is that plug-in hybrids need a much larger and more costly battery pack．【C14】______ a Pirus to operate as a plug-in hybrid, as some enthusiasts have done, costs around ＄12,000.
GM bosses have hinted that his company planned to put a plug-in into mass【C15】______ . It is an indication of how the pace is 【C16】______ in the race to develop more eco-friendly cars.
Others are more【C17】______ . Carlos Ghson, the boss of Renault and Nissan, who is 【C18】______ for his skepticism towards hybrids, said he still had doubts that hybrid technology is【C19】______ for the mass market, stressing that plug-in hybrids will have to wait until battery technology improves. Toyota has also been【C20】______ about plug-ins, insisting the Pims' approach is more convenient.

At first there may be good feelings too. A new and better job is just around the corner. It's nice to be able to lie in bed in the morning or spend more time with the children; have more time to think. But, unless a better job does turn up, the chances are the days start getting longer. and time becomes harder to fill. (31) Many people pass through periods of difficulty in sleeping and eating. They feel irritable and depressed, often isolated and lonely.
Despite all these problems though, unemployment can be a chance for a fresh start. You can discover that (30) it provides an opportunity to sort out or rethink what you want from life and how best you can get it. (31)You can use the time to plan how to field a new job, learn a new skill, develop your hobbies or see if you can run your own business.

The authors' research led to a new and telling discovery: that every leader, regardless of age, had undergone at least one intense, transformational experience -- what the authors call a "crucible" (severe test). These events can either make you or break you. For emerging leaders, they do more making than breaking, providing key lessons to help a person move ahead confidently.
If a crucible helps a person to become leader, there are four essential qualities that allow someone to remain one, according to the authors. They are: an "adaptive capacity" that lets people not only survive inevitable setbacks, heartbreaks, and difficulties but also learn from them; an ability to engage others through shared meaning or a common vision; a distinctive and compelling voice that communicates one's conviction and desire to do the right thing; and a sense of integrity that allows a leader to distinguish between good and evil.
That sounds obvious enough to be commonplace, until you look at some recent failures that show how valid these dictums (formal statements of opinion) are. The authors believe that former Coca Cola Co. Chairman M. Douglas Ivester lasted just 28 months because "his grasp of context was sorrowful". Among other things, Ivester degraded Coke's highest-ranking African-American even as the company was losing a ＄200 million class action brought by black employees. Procter & Gamble Co. ex-CEO Durk Jager lost his job because he failed to communicate the urgent need for the sweeping changes he was making.
It's striking, too, that the authors found their geezers (whose formative period, as the authors define them, was 1945 to 1954, and who were shaped by World Wm' Il) sharing what they believed to be a critical trait -- the sense of possibility and wonder more often associated with childhood. "Unlike those defeated by time and age, our geezers have remained much like our geeks (who came of age between 1991 and 2000, and grew up ' virtual' , ' visual' , and ' digital' ) -- open, willing to take risks, hungry for knowledge and experience, courageous, and eager to see what the new day brings", the authors write.
The passage indicates that leadership research ______.
