放言高论 meaning in English

have a highflown talk

She could not help but measure the professors , neat , scholarly , in fitting clothes , speaking in well - modulated voices , breathing of culture and refinement , with this almost indescribable young fellow whom somehow she loved , whose clothes never would fit him , whose heavy muscles told of damning toil , who grew excited when he talked , substituting abuse for calm statement and passionate utterance for cool self - possession
而马丁呢，是个几乎难以描述的年轻人，而她却不知怎么爱上了他。他的衣着从来就不称身，一身暴突的肌肉说明做过沉重的苦役。一说话就冲动，不是平静地叙述而是咒骂，不是冷静地自律而是激动地放言高论。
