    阅读理解。
         My friend Matt and I arrived at the Activity Centre on Friday evening. The accommodation wasn't
    wonderful, but we had everything we needed (beds, blankets, food), and we were pleased to be out of the
    city and in the fresh air. 　　
         On Saturday morning we met the other ten members of our group. Cameron had come along with
    two friends, Kevin and Simon, while sisters Carole and Lynn had come with Amanda. There were some
    other members I didn't know. We had come from different places and none of us knew the area. 　　
         We knew we were going to spend the weekend outdoors, but none of us was sure exactly how.
    Half of us spent the morning caving while the others went rock-climbing and then we changed at
    lunchtime. Matt and I went to the caves (岩洞) first. Climbing out was harder than going in, but after a
    good deal of pushing, we were out at last. Though we were covered with mud, we were pleased and
    excited by what we'd done.
