问题   Throughout history,people had dreamed about joining England and France together.Even Napoleon had a plan to dig a tunnel(隧道)and reach England.One of the first people who tried to dig a tunnel under the Channel(英吉利海峡)was a French engineer called Albert Mathieu.His tunnel failed.
  In 1 88 1,Colonel Beamont and Captain English from Britain also tried to dig a tunnel.Their tunnel went six kilometers into the Channel.Queen Victoria stopped them and said it was dangerous to connect with France.It was a very good tunnel,and it is still there today.
  The new tunnel(ready in 1993)is,in fact,three tunnels—tw0 for trains and a“service tunnelfor fresh air to go in and for men who take care of the tunnels.The tunnels are fifty kilometers long,forty meters under water.Forty kilometers of tunnel are under the sea itself.They are the longest undersea tunnels in the world.Trains travel through the tunnels at 160 km/h.People drive their cars onto trains and the trains take them through the tunnel.Each train takes 1,500 people and there are trains every ten minutes.
  A special radio station called Channel Channel has started,because it is impossible to receive normal radio signals(信号)when you are under the sea.The station sends news to keep people up—todate with the“world outside”while they are in the tunnel.
What’s the traveling like in the tunnel?

选项 A、Trains and cars can travel at 160 km/h
B、People can travel by trains through two tunnels.
C、It takes ten minutes to go through the tunnel by train.
D、People can drive their cars or hake trains through the tunnel.

答案B

解析 由“in fact,three tunnels--two for trains and a‘service tunnel’for fresh air to go in andfor men who take care of the tunnels”可得知。
