　　The study of law has been recognized for centuries as a basic intellectual discipline in European universities. However, only in recent years has it become a feature of undergraduate programs in Canadian universities.
　　几个世纪以来，有关法律的研究一直被看成是欧洲各国大学的一门基本的知识学科。不过，只是在近几年有关法律的研究才成为加拿大大学本科课程的一个专题。
　　①首句较为简单，主干为主谓宾的被动形式 = the study of law/ has been recognized as / a basic intellectual discipline. =有关法律的研究一直被看成是一门基本的知识学科。for centuries 和in European universities 为句子的时间状语和地点状语。
　　②二句为倒装结构，语法规则为:only 状语位于句首或主语之前时，主句半倒装（has it become a …）。如果对待倒装理解困难时，可将句子的主干和修饰成分进行拆分之后，将半倒装句改写会正常的语序，则整个句子重组为：only in recent years it has become a feature of undergraduate programs in Canadian universities. = 只是在近几年 它才成为加拿大大学本科课程的一个专题.
　　概念解释：半倒装句，即：部分倒装句：只把谓语的一部分（如助动词、情态动词等）移到主语之前,或把句子的强调部分提前.
　　例：only once was John late to class. 这里只是将助动词(be动词)was移到主语John前面,而实意动词late仍在主语后面,所以是部分倒装,即半倒装句.注意：以否定词开头的句子要“半倒装,如：no, not, never, seldom, little, hardly, at no time, in no way, not until等词在句首,句子要倒装.例：Not until yesterday did little John change his mind.直到昨天小约翰才改变了主意.Never have I seen such a performance. 如果否定词不在句首,则句子不倒装. 例：I have never seen such a performance.
