I watched from the back door and saw a strange door on the side of the flying saucer.Then I saw a strange man walk out.He had two bright green eyes and he was moving towards me.Oh,he must be an alien(外星人)!He was tall.He didn't look scary(受驚的) but had a smile on his face.He looked so f(106)riendly.The alien saw my cat and played with it happily.Then he walked to the garden.He p(107)ickedsome flowers and took some with him.He smelt and made a big noise.That woke up my parents and also my n(108)eighbors.Everyone came to see what h(109)appened.When they saw the alien,they were a little scared.The alien was happy,and then he turned around and walked into the flying saucer.Then it flew away and we couldn't see it any m(110)ore. Suddenly my mum saw some strange flowers that she had never seen before in the garden.My mum said they must be the alien's special p(111)resentsto us.
