[C]摘要；文摘►digestionn[U]&[C]［常用单数］消化；消化能力digestv.知识拓展Somebooksaretobetasted,otherstobeswallowed,andsomefewtobechewedanddigested.书有可浅尝者，有可吞食者，少数则须咀嚼消化。这句话出自弗朗西斯·培根的《培根随笔》。原句为：书有可浅尝者，有可吞食者，少数则须咀嚼消化。换言之，有只需读其部分者，有只须大体涉猎者，少数则须全读，读时须全神贯注，孜孜不倦。指出了“粗读、泛读、精读”三种不同读书方法。弗朗西斯·培根（FrancisBacon）是英国文艺复兴时期散文家、哲学家。英国唯物主义哲学家，实验科学的创始人，是近代归纳法的创始人。
