During summer vacation，I went on a three-day camping expedition（远足）. We had to carry all of our own clothes and food as well as tents cooking pots and first aid kits.
On the first day，our instructor taught us how to read maps. However walking with a 13-kg backpack under the burning sun was not the most ideal situation. Each of us had to carry two liters of water to drink as well. My group set off at 9：00 a. m. full of confidence but soon found ourselves lost on a farm!Luckily，each group had a tracker（跟踪器） that allowed our instructors to see where we were. We finally got to camp at 7 p. m. Having walked 25 km over 10 hours，my body was aching.
The third day was a bit easier. You couldn't imagine how excited we were although we were very exhausted.
It is not just about learning to read maps but also teamwork and how to deal with emergency situations. It pushed me to achieve something I never thought I could do and gave me important life experience.
A. I learned so much from this expedition.
B. It's not too difficult to understand the maps.
C. We were quickly found and got back on the right path.
D. On the second day，we had to find our own way to the next campsite.
E. We successfully made it back to the car park where our coach was waiting.
