托福阅读长难句：食用绿色食品

　　As a result，claims that eating a diet consisting entirely of organically grown foods prevents or cures disease or provides other benefits to health have become widely publicized and form the basis for folklore.

　　(同位语从句claims that…)

　　结果，那些认为只食用绿色食品就能防治疾病或增进健康的观点广为人知，并成为一些民间说法的基础。

　　分句1： that eating a diet consisting entirely of organically grown foods prevents or cures disease or provides other benefits to health

　　分句2： claims have become widely publicized and form the basis for folklore

　　分句1作为分句2主语 "claim" 的同位语从句嵌套在分句2中。因此本句的主句就是分句2. 同位语从句是that eating a diet consisting entirely of organically grown foods prevents or cures disease or provides other benefits to health：吃有机食品就能防治疾病或增进健康。
