     The train I was travelling on was already half an hour late. I had to arrive in Vienna at 7:15 in time to

catch the   7:25 train  to Paris,  but there  was  no hope of  that now. I told the conductor about it . He

advised   me  to  get off  two stops  before Vienna  station and take a  taxi .  When the time came,  the

conductor even helped me with my bags. He wished me good luck as I jumped off. And a few minutes

later, I was racing towards the centre of the city in a taxi.   It was almost 7:25 when we stopped outside

the sta?tion. I paid the driver quickly, took hold of my bags quickly and hurried inside. "Paris train" was

all I had time to say to the official (铁路职工) I saw.  You can guess how  I feel when he pointed  to a

train that was just moving out of the station.
