通读下面短文，掌握其大意，然后从短文后各题所给的四个选项中选择能填入相应空白处的最佳选项。
        Andy Barton worked in an office. He was in a     1     mood (心情) this Friday.
        At six o'clock his favourite programme "Travel with it!" was on TV. Andy liked to get home in good time
for that, so he was leaving the office a little     2    .
        "I can get home in time if I hurry." Andy told himself when he     3    out of the office. But when he drove
off in his car, he    4      that he was almost out of gas (汽油). "I'll have to stop at Fenton's." Andy thought. He
     5     Fenton's because it was a self-service gas station. You do all the work yourself, but you pay     6    for
the gas. Fenton's pump (泵) was not working properly and it     7     too much time to get gas.
        So when Andy got home, it was already two minutes past six. Just then the phone rang. "Shall I answer
it?" Andy thought. He tried to fix his attention on the programme and forgot the phone. But it kept on ringing and
finally he picked it up.
         "Mr. Barton?"     8    said, "Fenton's Garage here."
         "Fenton's?" said Andy, "      9     , I was at your place only a few minutes ago, getting some gas. Did I
    10      something behind or what?"
         "No, you didn't. Mr. Barton." the voice went on. "That's just the point! You didn't leave anything behind!
You went off without paying for your gas, you see! When that happened, we usually ring up the police. But 
    11      I recognized you and I know it was a mistake."
         "I'm really very sorry." Andy said. "
         Oh,    12     , Mr. Barton. But could you come round now and pay for your gas? And please hurry! We
close at half past six!"
