问： just because you've been working in a field for many years doesn't mean you have to turn that parrern fo work into your career. 这句话里有because引导的主语，但好像because不是主语引导词，所以，这句话有错误， 对巴
because是不能引导主语从句的，这一点是肯定的。 其次呢，这句话确实有错误，如果想表达同样的意思可以说成：It's true that you've been working in a field for many years, but it doesn't mean you have to... 虽然改动有些大，但是应该还是比较符合英语习惯的，原来的那句话感觉好像是从中文语感来的：仅仅因为你……，呵呵，中文说着舒服，但是英语方面是不对的。 反正，because就是不能引导主语从句啦！我太罗嗦了！
