阅读理解An elderly woman died and several other passengers were critically injured when a crowded Virgin express train crashed in Cumbria last night. A huge rescue operation involving RAF helicopters and dozens of ambulances arrive. After passengers were trapped in the train for more than four hours because fallen power line poles made access for emergency workers difficult. Authorities reported up to 80 injuries. Thirteen people were taken to hospital in a“critical or serious condition.” Between 180 and 200 passengers were on the 5:15pm Virgin service from London Euston to Glasgow Central when all nine carriages left the rails between Oxenholme and Tebay. Witnesses said that the train shook violently before toppling(倾斜) over into an embankment(筑堤)with at least four carriages overturning. Early this morning, authorities confirmed an elderly woman had died and some other passengers had suffered injuries including back strains, head wounds and broken bones. Ruth Colton, a passenger on the train, said she was reading a book when the journey became unfortable. It seemed that the train was being beaten by heavy winds,“as if we were on a plane”. The accident brought concerns that Britain's busiest rail route would be crippled(瘫痪)for some time. The line between Preston and Carlisle was postponed as Virgin Trains promised a rapid investigation into the “serious incident”—the pany's first big crash. It is understood that the investigation will examine whether there was an obstacle on the track and the possibility of speeding or mechanical breakdown. The driver, who was injured, will be interviewed and a black-box recorder installed in the train will be examined.1.What made the rescue e so late?A.It's not accessible to reach the accident spot.B.No enough helicopters and ambulances could be found at that time.C.It was too far from hospital to Cumbria.D.No one called the emergency center.2.According to the passage, the busiest rail route in Britain is          A.From Preston to CarlisleB.Between Euston and GlasgowC.From Oxenholme to TebayD.Between Virgin and Pendolino3.What does the underlined word “critical”mean?A.Important.B.Careless.C.Dangerous.D.Surprising.4.Which of the following is the possible cause of the accident?A.Careless driving.B.Heavy wind.C.Over loading.D.Obstacle on the track.5.We can learn from the passage that Virgin Trains               A.made no quick reaction to this accidentB.seldom had so serious an accident beforeC.had made full preparations for the accidentD.didn't mind how many passengers the train can hold
