假定你是李华，正是英国牛津参加短期语言培训，计划星期天去伦敦旅游。互联网上一则广告引起了你的注意，

　　Dear Sir/Madame,I’m writing for more information about the day tour to London.As a student at Oxford University, I’d like to know if you have any special price for students. As for the money you charge, does it cover the entrance fees for visiting the places listed? What about lunch? Is it included? Or do I need to bring along my own food?How long will the tour last? Since I need to prepare my lessons for the nest day, I’d like to know the time to return. Besides, is there any time for shopping? I really want to have a look at the big stores in London.Yours,Li Hua[名师点评]
