Read the following passage and choose the correct answers. Amy Tan, the American-born daughter of Chinese immigrants, received the Commonwealth Club Gold Award in 1989 for her first work of fiction, the best-selling Joy Luck Club. The sixteen interrelated stories that constitute the work alternate between the tales of four Chinese immigrant mothers and their Americanized daughters, in an exploration of the generational and cultural tensions experienced by first-generation daughters of immigrants. Tan’s parents, like many, immigrants, had high expectations for their children and often .set confusing standards, expecting Amy and her two brothers to think like Chinese but to speak perfect English, excel academically, and take advantage of every circumstance that might lead to success. Tan, however, rebelled against her parent's expectations, which included such exalted professions as neurosurgery and devoted herself to being thoroughly American and dreaming of being a fiction writer. Tan obtained a bachelor’s degree in English and linguistics and a master’s degree in linguistics and eventually established herself as a highly successful business writer. Tan, however, was not satisfied despite her material success. Turning to her lifelong dream, she wrote her first short, "Endgame”; and then a second, "Waiting between the Trees". In 1987 Tan visited her half sisters in China with her mother, a trip that proved to be a turning point in her life and career. Tan felt a sense of completeness, a bonding with the country and its culture that she had never expected. Returning from China, Tan was surprised to learn that on the strength of her short stories she had received an advance from the publisher. Tan closed her business and wrote the remaining stories for the Joy Luck Club. It was a resounding success, well received by the critics and appearing on the New York Times bestseller list.
