An experimental solar-powered plane landed safely Thursday after completing its first 24-hour test flight, proving that the aircraft can collect enough energy from the sun during the day to stay aloft(在空中) all night.

       Pilot Andre Borschberg eased the Solar Impulse onto the runway at Payerne airfield about 30 miles southwest of the Swiss capital Bern at exactly 9 a.m. (3 a.m. EDT) Thursday. Helpers rushed to stabilize the pioneering plane as it touched down, ensuring that its massive 207-foot wingspan didn't scrape the ground and topple(傾倒) the craft.

       The record feat(壯舉) completes seven years of planning and brings the Swiss-led project one step closer to its goal of circling the globe using only energy from the sun. ‘We achieved more than we wanted. Everybody is extremely happy,’ Borschberg told reporters after landing.

       Previous flights included a brief ‘flea hop’ and a longer airborne test earlier this year, but this week's attempt was described as a ‘milestone’ by the team. The team said it had now demonstrated that the single-seat plane can theoretically stay in the air indefinitely, recharging its depleted batteries using 12,000 solar cells and nothing but the rays of the sun during the day. But while the team said this proves that emissions-free air travel is possible, it doesn't see solar technology replacing conventional jet propulsion(噴氣推進(jìn)) any time soon. Instead, the project's overarching purpose is to test and promote new energy-efficient technologies.

       Project co-founder Bertrand Piccard, himself a record-breaking balloonist, said many people had been skeptical that renewable energy could ever be used to take a man into the air and keep him there. ‘It’s a matter of time that people come to believe and understand about renewable energies,’Piccard said, adding that the flight was proof that new technologies can help break society's dependence on fossil fuels.

       The team will now set its sights on an Atlantic crossing, before attempting a round-the-world flight in 2013, making only five stops along the way. ‘It's absolutely not time to relax,’ said Piccard.

閱讀下面短文，回答后面的問(wèn)題。(共5小題；每小題2分，共10分。)

[1]The cigarette industry began in the 1870s with the development of the cigarette manufacturing machine. This made it possible to produce great numbers of cigarettes very quickly. And it reduced the price.

[2] Today cigarette smoking is a wide –spread habit . About forty percent of the adult men and thirty –one percent of the adult women in the US smoke cigarettes regularly. It’s encouraging to note, however, that millions of people have given up smoking habit. Seventy-five percent of the male population and forty-six percent of the female population have smoked cigarettes at some time during their lives, but twenty-six percent of these men and eleven percent of the women have stopped smoking. The number of the persons who have given up smoking is increasing.

[3]Income. education, and occupation all play in determining a person’s smoking habit. City people smoke more than people living on farms. Well-educated men with high incomes are less likely to smoke cigarettes than men with fewer yeas of schooling and lower income. On the other hand. If a well-educated man with a higher income smokes at all, he is likely to smoke more packs of cigarettes per day.

 [4]                     . There are slightly more smokers among women with higher family incomes and higher education than among the lower incomes and lower education group, These more highly educated women tend to smoke more heavily,

 [5]Among teenagers the picture is similar. High school students who are preparing for college are less likely to smoke than those who do not plan to continue their education after high school. Children are most likely to start smoking if one or both of their parents smoke.
