As we all know,almost everyone has many unforgebbable moments in his memory..So do I.If there is one single word can describe it,it must be surprised.
Last summer holiday,I went to Shanghai.I had not been there for a long time.I was surprised to see the quick development in Shanghai.I saw mordern highrises here and there.The public traffic was orderly and safe.Nanjing Road Walkway was crowded with visitors from other places.They could buy all kinds of goods from the whole world.What’s more,I saw that the Shanghainese who had good manners helped the old cross the road and give others a hand.
What great changes the beautiful city has!Every time I think of the visit to Shanghai,I always feel very happy and proud.
