［1］To most Chinese students, studying abroad could be hard work. There are lots of difficulties they should face every day—the language barrier, culture shock, gaps between Eastern and Western lifestyles, expensive tuition fees and endless research projects.
　［2］To Song Yinan, a 19-year-old Shenzhen girl, however, studying abroad was an unforgettable experience. In her book, “Kiki’s London Diary”, she tells her stories in an optimistic way.
　［3］Probably the biggest difficulty Chinese students will meet is ___________. For example, in a story written at the beginning of her first term in London, Song suffered some embarrassment during a welcome party, where she was introduced to some dizzy drinks. However, she found that she couldn’t read most of the English names of the drinks and drank only cola and fruit juice. She described how red her face was and also the impatience of some other students as they stared the poor girl.
［4］Song says in an interview that it is still a good experience for her anyway. Although it sounds like “losing face” to most Chinese students, she says it is normal when you study abroad and she is happy to share the story with others.
　［5］During her stay in Britain, Song was like an explorer. She discovered happiness in London everyday. She found happiness in a computer on which she could search for information on Chinese websites, at a low-price grocery, and form making friends with Britain students.
　［6］Song was a high school student then and had never traveled abroad alone before. This is why Song’s parents say in the book’s forward that they were a little bit worried about their daughter.
　［7］However, throughout the book, readers can feel the optimism and persistence of this strong-willed girl. Her study and life experiences in London are to delight any Chinese studying abroad or who plans to do so.
