My classmates and I went to the mountain behind our school to play yesterday.Suddenly, we discovered a spaceship.And two aliens were standing beside it.They felt surprised when they saw us.They were not tall and did not have any hair.They were aliens with two long ears.Then,they used a strange language to shout at us angrily.We answered but they didn't understand us as well.After a few minutes,we have thought a good idea to communicate with them.We had no choice but to use body language.We tried smiling at them to make them feel friendly.They appeared friendlier than before and didn't shout.Next,we spread our arms to hug them.They didn't refuse to hug us.After half an hour,we and aliens became friends although we didn't understand each other's languages.It was late.Finally we arrived home. What a exciting day!
