逻辑图
P1: food intolerance研究的起源
1、引出话题(it must be rare)
2、Food intolerance研究追溯到N...的发表(yet,trace their interest back)
3、M提出概念(but)
P2:讲述M发现food intolerance的过程
P3:讲述M做实验
P4:food intolerance概念被广泛接受,也被质疑
1、被广泛接受,也被质疑(has much wider acceptance & one of scepticism)
2、被质疑的原因(stems from & moreover)
3、研究这一领域的医生意识到需要研究潜在的机制(realise)
P5:研究的结论
1、研究的结论转变(historically linked with...and until relatively recently)
2、过敏的原因(the cause of)
Simple story
P1:
1、引出话题(it must be rare):introduce a radical new idea into medical thought
2、Food intolerance研究追溯到N...的发表(yet,trace their interest back)
3、M提出概念(but)
P2:讲述M发现food intolerance的过程
P3:讲述M做实验
P4:
1、Food tolerance has much wider acceptance & scepticism
2、The cause of the scepticism--lack of mechanism & cannot answer the question (why should symptoms appear in every patient)
3、研究这一领域的医生意识到需要研究潜在的机制
P5:研究的结论
1、研究的结论转变:food intolerance以前跟食物过敏有关→跟免疫系统的mechanism有关
2、过敏的原因(the cause of):抗生素→binding to antigen→释放mediators→dramatic effect on the body(小量、大量)
