I chose to study engineering at a small liberal-arts university that doesn't even offer a major in electrical engineering. Obviously, this was not a practical choice; I came here for more noble reasons. I wanted a broad education that would provide me with flexibility and a value system to guide me in my career. I wanted to open my eyes and expand my vision by interacting with people who weren't studying science or engineering. My parents, teachers and other adults praised me for such a sensible choice. They told me I was wise and mature beyond my 18 years, and I believed them. I headed off to college, feeling sure I was going to have an advantage over those students who went to big engineering "factories" where they didn't care if you had values or were flexible. I was going to be a complete engineer: technical genius and sensitive humanist all in one. Now I'm not so sure. Somewhere along the way my noble ideals crashed into reality, as all noble ideals eventually do. After three years of struggling to balance math, physics and engineering courses with liberal arts courses, I have learned there are reasons why few engineering students try to reconcile engineering with liberal-arts courses in college. The reality that has blocked my path to become the typical successful student is that engineering and the liberal arts simply don't mix as easily as I assumed in high school. Individually they shape a person in very different ways; together they threaten to confuse. The struggle to reconcile the two fields of study is difficult. The author chose to study engineering at a small liberal-arts university because he ______. A．intended to be a sensible student with noble ideals B．wanted to be an example of practicality and rationality C．intended to be a combination of engineer and humanist D．wanted to coordinate engineering with liberal-arts courses in college 此题为多项选择题。
