This summer, I was lucky to have joined an archaeology summer camp, which lasted ten
days. During the summer camp, we visited several museums which many valuable cultural relics
were displayed. Even more excited, we got a chance to go to an archaeological site. It was the
first time that we had been very close to ancient civilization that I could witness how the digging
was carried out. The speeches were made by famous archaeologists informed us on much
knowledge about this field. Besides,I make many friends who are interested in archaeology and
we are still in constantly touch now, talking about how we like.
