7、One possible version

 Good evening，ladies and gentlemen，

    My name is Li Hua．I have the honor of being your guide tomorrow, Now I'd like to give you a brief introduction to our tour．   

    We’ll meet at the school gate at 8：00 am and set off by bus．As the old Chinese saying goes，“He who does not reach the Great Wall is not a true man”．The first place we will visit is that world famous spot．When you are standing on the wall，you will feel amazed at this man-made wonder on earth．After two hours there，we’ll leave for a snack street where varieties of foods will be waiting for you to try．The afternoon tour will begin from the Summer Palace at about 2：00 pm．You can take a boat to enjoy the beautiful scenery in the garden and feel free to look around there until 4：00 pm．In the evening，we will watch a wonderful Beijing opera which will let you experience a real Chinese culture．After the show, we'll return to the school at about 9：00 pm．

    Thanks for your listening and I hope you can enjoy your tour tomorrow．
