　　B

　　Around every Lunar New Year holiday，China becomes a country on the move.The holiday crush(客流量)this year is estimated to be even heavier than before.

　　Government officials suggest that Chinese people will take to the air，roads and railways 3.62 billion times over a 40­day period around the nation's most important holiday this year as people push their way home for family gatherings or to satisfy their new­found passion for travel.

　　Getting tickets to all those would­be travelers is a discounting challenge that tries your patience annually.And the pressure for the railway system is always the greatest.Railways are the transport of choice for low­cost long­distance travel，and that's where the ticketing system regularly falls down.

　　Much of the criticism has focused on the railway's online purchasing system，which has been unable to keep pace with the huge demand and also failed to stop scalpers(票贩子)from easily getting many of the hard­to­find tickets.

　　Railway officials believed that online sales were the fairest way to get tickets for travelers，and told reporters that the public need to be patient.While by now the railway service is far from satisfying，efforts are being made to provide online identity checks that would reduce the ticket scalping problems，and the situation is expected to get better in a few years.Meanwhile，for those traveling by car，good news is that the country's extremely expensive highway tolls(通行费)will be removed for the period of the official holiday.
