Unit 4 Astronomy: the science of the stars

话题：职业选择

【场景背诵】－－体会黑体表达并背诵全文

When I graduated from high school, I wanted to major in comparative literature. But, once I found out my friends were going into “real” majors, like marketing, nursing, and engineering, I figured I needed to do the same to ensure a good career. So I changed my mind and chose Business Management as my major. I forced myself to believe that I would enjoy it and succeed in the future, but eventually I exhausted myself understanding the economy and trying new marketing techniques. Coming out of this experience, I realize it is OK to be different from others and to study things like classics, art history and other majors offered in the College of Humanities (人文学科)!
