[单项选择]Passage 2

A great horned owl hoots across the quiet water-and then glides through the stand of bald cypress along the eastern side of the swamp. Whip-poor-wills call; bullfrogs croak; mosquitoes hum. Darkness creeps across the swamp. (71) Offering a different set of treats every season, the refuge attracts a wide variety of visitors during the hunting season, during the fishing season, and during the bird-watching season. (72) Canada geese far outnumber other waterfowl, but snow geese, blue geese, and occasionally white-fronted geese winter there, too. Nearly every variety of duck, diver and puddle, reside in the quiet, smaller sloughs. As a result, the swamp attracts hunters in ’early winter, goose hunters to the pits and duck hunters to the blinds. The hunters’ closely regulated success is the result of hundreds of acres of corn left standing by Pose County farmers, who rent the rich bottom land between the lake and the river

Across the English Channel

To swim across the English Channel takes at least nine hours. It’s a hard work and it makes you short of breath. To fly over the Channel takes only twenty minutes (as only as you’re not held up at the airport), but it’s an expensive way to travel. You can travel by hovercraft if you don’t mind the noise, and that takes forty minutes. Otherwise you can go by boat, if you dreams of being able to drive to France in his own car. "Not possible", you say. Well wait a minute. People are once again considering the idea of a Channel tunnel or bridge.
This time, the Greater London Council is looking into the possibility of building a Channel link straight to London. A bridge would cost far more than a tunnel, but you would be able to go by rail or by car on a bridge, whereas a tunnel would provide a rail link only.
Why is this idea being discussed again Is Britain becoming more conscious of the need for links wi
A. Swimming across the Channel takes less than four hours.
B. The idea of a Channel tunnel or bridge is a very new one.
C. It is considered to be more difficult to swim across the channel than any other means.
D. A tunnel or bridge would only reach as far as the coast.
