     With a growing number of people in San Francisco choosing not to own a car,German carmaking company BMW has decided to branch out into car-sharing services with 70 cars spread around the city,first in 14 locations,with a further 100 being added gradually.

    “This is not an A-to-A service A-to-B” says Richard Steinberg,chief executive of the DriveNow scheme(方案) ，pointing out that members can pick up a car downtown for the half-hour drive to the airport for only $12,compared with about $40-50 for a taxi.

Whether that is possible in real life depends on traffic,of course. A midmoming drive from Union Square down Highway 101 to the airport takes just 22 minutes; however,driving back during the rush hour takes twice as long.

    Most of the cars that are stuck in San Francisco's traffic jams are giving off all sorts of harmfiil gas. But not DriveNow’ s BMW ActiveE cars.

    “All the cars in San Francisco are electric,” Mr Steinberg says.

     In San Francisco,handing back the car to DriveNow is easy — just pick one of its drop-off points,park and walk away. There are no forms to fill in,no time-consuming(耗時(shí)的) rules.

Several other carmakers and other players within the motor industry are experimenting with similar schemes,for example Daimler,s Car2go scheme,which is operated in many cities around the world.

    “We picture a future where car-sharing members outnumber car owners in big cities around the world” says Car2go spokesman Andreas Leo.

    Franck Leveque,from company Frost & Sullivan,agrees. 

    “Car sharing is growing at a pace we have not seen before,” he says. “By 2020 we believe there will be 15 million members of car-sharing schemes in Europe alone,Nyith 140,000 vehicles in operation."

28. What does the underlined part “branch out into” probably mean?

   A. Start offering.        B. Stop improving.

   C. Make use of.          D. Take control of.

29. The DriveNow scheme .

   A. works better in rush-hour traffic

   B. makes city driving less dangerous

   C. encourages people to buy a cheap car

   D. allows drivers to pay money to use a car

30. What' s special about BMW ActiveE cars?

   A. They drive much faster than other cars.

   B. They never get stuck in heavy traffic.

   C. They don't harm the environment.

   D. They need less gas to run.

31. What does Franck think of the future of car sharing?

   A. Worrying.           B. Hopeful.

   C. Uncertain.          D. Disappointing.

      I learnt to fly in a balloon in a race across the Atlantic Ocean in 1992 and became extremely interested in the sport. In the same way that a mountain climber dreams of climbing the world's highest mountain,I dreamed about flying non-stop around the world.

       I spent six years planning the flight and failed twice before I and my team managed to succeed. For some reason,we had to go first to North Africa to catch the right winds. That added 10 ,000 kilometres,and another week,to our journey. But because of this,our flight broke all the records for distance and time spent in the air.

      The most memorable part of the trip for me is that we lived in the air for 20 days and that the rising sun was the most amazing thing we saw. We had to go out of the balloon’s capsule (艙) , in which we were transported,three times while in the air to repair the fuel(燃料) system. We didn’ t have any safety equipment but when you are in a situation like that,you just do what you have to do without thinking about feeling afraid.

      Landing was a fantastic moment. I remember that when I got out of the capsule,I looked at my footprint in the sand. I remembered the astronaut Neil Armstrong,who was so happy to put his footprint on the moon,so far away from Earth. At that moment,I was so happy to have my foot back on Earth! 

21. The author became interested in ballooning because of .

   A. a cross-ocean race

   B. a mountain climb

   C. a childhood dream

   D. a long sea journey

22. What can be inferred from Paragraph 2 about the author and his team's flight?

   A. They set a new record.

   B. They shortened their flight.

   C. Their flight went very smoothly.

   D. Their flight covered 10,000 kilometres.

23. Why did the balloonists get out of the capsule during the flight?

   A. To fight their fear.

   B. To do some repair work.

   C. To admire the rising sun.

   D. To check safety equipment.

24. The author mentioned Neil Armstrong to show his .

   A. regret         B. surprise

   C. respect        D. pleasure
