【題目】Superfast doubledecker (雙層) trains will be taking passengers from London to six big cities in the UK by 2033. The first phase (階段) linking London to the West Midlands with a connection to HS1 is expected to open in 2026, and the second phase to Manchester and Leeds in 2032.

The government set out a plan for the highspeed rail network in 2012. When the project is finished, it will take less time to get to London from major cities like Birmingham, Manchester and Leeds. Traveling at a speed of up to 250 mph, passengers will be able to come and go from Birmingham to London in 49 minutes, reducing the journey time by almost half from one hour and 24 minutes.

A journey from Birmingham to Leeds will be reduced from two hours to 57 minutes and a journey from Manchester to London will be reduced from two hours and 8 minutes to one hour and 8 minutes.

“HS2 is an important part of transport's lowcarbon future,” Transport Secretary Justine Greening said. Some people aren't happy about the plan, though. HS2 will cost around £33 billion. It will also be built near some towns and villages, disturbing the people that live there.

A. To buy some doubledecker trains.

B. To take passengers to Manchester from London.

C. To build a highspeed train network.

D. To collect £33 billion for the highspeed train network.

【2】How long does it usually take you to travel from Birmingham to London by the ordinary train?

A. 49 minutes.B. One hour and 24 minutes.

C. 57 minutes.D. Two hours and eight minutes.

【3】What can NOT be inferred from what Justine Greening and George Osborne said?

A. HS2 is more important than HS1.

B. Not all British people are happy about the plan.

C. The British will benefit from the project in the future.
