      It was already dark when we left for the next town,which according to (根据) the map was about
fifteen miles away on the side of the hills．There we felt   1   that we would find a bed for the night．
Darkness fell soon   2   we left the village, but luckily we met no one as we drove quickly along the
narrow winding (弯曲) road that   3   to the hills．As we climbed higher,it became colder and rain
began to fall,making it difficult   4   to see the road．I asked John,my friend,to drive more slowly．
       After we had traveled for about twenty miles,there was still no   5   of the town which was marked
on the map．We were beginning to get worried．Then,without   6   ,the car stopped．A quick   7   
showed that we had run out of petrol (汽油)．Although we had   8   food with us,only a few biscuits
(饼干) and some chocolate,we decided to spend the night in the car．
       Our meal was soon over．I tried to go to sleep at once,but John,who was   9   ,got out of the car
after a few minutes and went for a walk up the hill．Soon he came running back．From the top of the
hill we had seen,in the valley (山谷) below,the  10    of the town we were looking for．We at once took
all our things out of the car,and tried hard to push the car to the foot of the hill．Then we went back for
the things,put them back into the car again and left the hill．In less than a quarter of an hour we were in
the town,where we found a hotel quite easily．
