     Saturday,                                                                                   June 16th  

     In the morning, we went camping along a path in Green Natural Park. We were happy because it

was a sunny day. We were expecting an enjoyable two-day holiday. On the way, we kept singing and

making jokes.

     However, in the afternoon, when we finished our picnic at one o'clock, it was dark and windy.

Soon, there was a shower. Unluckily, none of us brought an umbrella. We ran about but we could find

no place to hide.

     Twenty minutes passed and it was still raining, There were hours to go before we reached the

campsite (野营地). It was even worse that our small compass (指南针) showed that we went to the

wrong way. We had lost our way!  

      We had to make a quick decision as it was raining heavily. Chris said we could set up a tent to hide

in, so Mary and Tom helped to set up the tent. Chris and I tried to make a fire to keep us warm. But we

were unable to light the fire, as everything was wet. We dried ourselves, chatted and waited inside the

tent. At about five o'clock, it stopped raining. We decided to give up the camping trip because all of us

had been very tired.

     This camping trip may not be very successful but we know each other better. And the most

important thing I've learned from this trip is the importance of team spirit.
