“Choo，Choo！”Here comes the Chunnel train. Get aboard if you want to learn more about this underground transportation system. This is an unusual form of transportation, because it is a tunnel that trains travel through and not an actual form of transportation.
The Chunnel is actually the English nickname for the Channel Tunnel. In French，it is called le tunnel sous la Manche. It is a rail tunnel beneath the English Channel at the Straits of Dover. It connects Cheriton in Kent, England with Sangatte in northern France. It is the second longest rail tunnel in the world.
Did you know that the British and the French had a race while they were building the Chunnel? The race was to see who could get to the middle of the tunnel first. The British won by a little bit. It took 15,000 workers over seven years to dig the tunnel. The tunnel was finished in 1994.
The completed Chunnel cost about $21 billion. But it all paid off, because it became very popular, very quick. Millions of people use it. Now it is getting even more popular.
There are three complete tunnels in the Chunnel. The two outside ones are the passenger trains. The small inner one is a guidance train. The guidance train is not used for transportation. Each track is exactly parallel to each other.
There are four different train systems in the Chunnel. The Eurostar is a high speed passenger service that connects London, Paris, Brussels and Lille. The Eurotunnel shuttle is a rail ferry service. These shuttles carry cars and vans. These are railcars that allow drivers to drive their vehicles on and off. There are also two Eurotunnel goods service trains.
Now you know more about the Chunnel. Everybody off，this is the last stop.

“Yes, ladies and gentlemen, welcome aboard NASA’s Space Elevator. We’re going to leave soon. The entire ride will take about five hours, so sit back and enjoy the trip. As we rise, be sure to look out the window. You’ll see the sky change from deep blue to black. It is one of the most wonderful views（景色）you will ever see! ”
Does this sound like the Sci-Fi Channel? Well, it’s not. Scientists are thinking that a “space elevator” will be possible toward the end of the 21st century. A space elevator will consist of a long cable (电缆) from the Earth’s surface into space to an altitude(高度) of about 35,786 km. “Elevators” will travel along the cable and move people and loads between Earth and space. One of the greatest advantages is that the cost will be much less. Researchers estimate (估计) that a passenger with baggage at 150 kg might cost only $222! Compare that to today’s cost of around $3.3 million for the same weight. It would make “cheap” space travel possible. Scientists believe carbon nanotubes (纳米管) may be used to make high-strength materials for the cables, although they are still being studied.
It was Arthur C. Clarke who brought this idea to the general public. In his science fiction novel Fountains of Paradise, engineers build a space elevator on top of a mountain peak on an island. One day, Clarke was asked a question by a student during his speech. The student asked when the space elevator would become a reality. Clarke answered, “Probably about 50 years after everybody stops laughing.” He’s got a point. When we stop thinking of something as impossible, then we start working on its development.
小题1:Why should passengers in a space elevator look out the window while they are moving into space?

A．Because the blue sky is very beautiful.

B．Because the view outside is wonderful.

C．Because the sky changes from black to blue.

D．Because the trip will take about seven hours.

小题2:Which of the following is NOT true according to the passage?

A．Scientists haven’t used carbon nanotubes to make the cables.

B．Traveling in space elevators will cost much less in the future.

C．Passengers will be able to travel in space elevators with baggage.

D．Space elevators will travel for 35,786 km around the Earth’s surface.

小题3:What is the best title for this passage?

A．Possible Now: Space Travel	B．Cheap Space Travel
C．Going into Space in an Elevator	D．Space Travel — Impossible
