The archeology class

Yesterday I took part in the archeology class outside.We took 45 minitutes to drive.And arrived there, Professer asked us to take protective actions because there are some poisonous plants and insects.After watching professor dug soil in special area,we started dug by ourselves.However,the bad weather seem to be rain,we left there right away.It's my first experience to attend this kind of class, I think it's meaningful and different from Chinese class.
