The world’s longest 3rd deepest railway underground passage, the Gotthard Base Tunnel, opened on 1 June 2016 after many years of construction. Trains can travel at speeds of up to 250 km an hour through the 57 km long tunnel. It took 17 years to complete and cost $12 billion. A total of 2,600 workers involved in building the tunnel had to excavate more than 28 million tons of rocks. Nine people died during the construction. The engineering milestone will bring southern Germany and northern Italy closer together.

    Gattardino shuttle trains will be running between the two endpoints of the tunnel and make a stop at Sedrun, a mountain station in the middle. 65 passenger and 240 freight(货物) trains are expected to travel through the tunnel every day. The Gotthard Base Tunnel will reduce the time it takes trains to pass through the Alps, which have been a natural barrier to travel. In the past traders and merchants had to use mountain passes to travel from north to south. The first Gotthard rail tunnel opened in 1882, but as time went on, it could not handle the growing traffic.

    In the 1990s, Swiss citizens approved of a government plan to build a new tunnel. The main purpose of the Gotthard Base Tunnel is to increase local transport capacity(容量) through the Alpine barrier, especially for freight. This not only significantly reduces the danger of deadly road crashes involving trucks, but also reduces the environmental damage caused by the ever-increasing amount of freight carried by heavy trucks. The new tunnel is expected to reduce road traffic crossing the Alps as more and more truck companies will put their freight on Swiss trains.

1.Which of the following can replace the underlined word “excavate” in Paragraph 1?

3.What can we learn from the text?

A. Gottardino shuttle trains will run through the tunnel without stopping.

B. More passenger trains will travel through the tunnel than freight trains.

4.Where is the text probably taken from?

A. A travel guide.    B. A fiction story.    C. A fashion magazine.    D. A news report.
