[问答题]So many high school graduates have no clues what they want to pursue as a career as they head off to college. So, here’s the question: How many times have you changed your major(s) while in college and what prompted the change(s)? The following are opinions from all walks of life. Read the excerpts carefully and write your response in about 300 words, in which you should:　　1. summarize briefly the opinions in the excerpts;　　2. give your comment.　　Marks will be awarded for content relevance, content sufficiency, organization and language quality. Failure to follow the above instructions may result in a loss of marks.Never Changed　　Claire | High School Teacher: I actually never changed my major. I declared elementary education immediately and stuck with it. I thought I wanted to minor in math, but before I even took a single math class, I ended up switching to English. Aside from student teaching and a long term sub position in 5th grade immediately following graduation, I’ve actually NEVER taught elementary school. I went ahead and took the Texas exam to get certified k-12 and I’ve only taught high school since. Sometimes I wish I had just done secondary education. Sadly, I don’t actually think any of my education classes in college affected the way I teach—experience has really been the best class I’ve had.　　Kevin | Accountant: I never changed my major in college! I knew exactly what I wanted, where I was going, and what I ultimately hoped to achieve after graduation with my AAS Degree in Business Management/ Accounting, I went directly to work in my chosen profession and never looked back! It served me well for about twenty-five years.　　Murphy | Middle School Teacher: I never changed my major in college, but I did not declare a major until the university forced me to. I majored in Political Science simply because it interested me. Of course, when I did declare this major everyone, especially my patents, asked me what I was going to do with it and my answer was always that I wasn’t sure. I ended up receiving a teaching credential two years after receiving my B.A. in Political Science and have been teaching for the last 26 years.　　Changed　　Dastice | Clerk: I changed my major from Psychology to Sociology. I still minored in Psych, and also in Women’s Studies. My only drive in changing majors was that I enjoyed the classes more. I figured if I stuck with what I enjoyed then a career would somehow emerge from it once I got my degree. Knowing what I know now, however, I probably would have majored in something like business or law. After graduating with my degree I ended up working jobs that didn’t even require a college education. Experience was far more valuable, I was told.　　Jenny | College Student: I, for some reason, never knew majors were a huge deal and could be almost as important as your life. I started out as an arts and Spanish major. I then realized the program my school offered for the education major took care of 4 classes I would have to take for my MA. I dropped the art major and went into the education major. My last semester came and I was at a crossroads: take the final course to complete my major in education or the class to complete my Spanish major. I do get a little upset thinking I was only one class away from another major.　　Gaha | Writer: I changed it once. I started college at eighteen and a little naive as to the working world. I chose to major in Business, not sure why, in fact I don’t think I really even knew what it entailed. It wasn’t until the onset of my junior year that I came to an epiphany that I had only take a couple of business classes because they bored me out of my mind. After taking a look at my transcript, realizing that I was totally into foreign languages and literature, I decided to get into writing. And a new writer was born!
