题型描述: 阅读理解When I lived in Canada, many people asked me about Chinese customs. I was happy to talk about our many lovely traditions, such as Spring Festival. But I was unprepared for the number of people who asked me about Japan, Korea, and India! It seemed unbelievable to me that so many people were unaware that China is a nation with its own tradition and history. Recently, while working on a new textbook at a publishing company, I asked a foreign colleague about weddings in Nigeria. She looked at me as if I were crazy, and said, ″How would I know? Iˊm from Canada.″ I told her that all foreign cultures are alike, so she should know. She threw her head back and laughed. ″Xiao Li,″ she told me. ″I donˊt mean to hurt your feelings, but all countries have customs different from one another! Didnˊt you tell me how angry you were when Western people asked you about Japan? Itˊs not just nations that are different: country people have different ways of celebrating from city people. Celebrations are different from family to family as well.″ At first, my feelings were very hurt, but then I realized she was right.
