2023中学生英语词汇辨析：worth, worthy 与worthwhile思维导图

worth价值，可贵之处，作形容词时与worthy和worthwhile都是"值得……"的意思，但用法不同，如：This book is worth reading./This book is worth 3 yuan?./It's wort hwhile to visit (visiting) this place./This place is worthy of a visit (visiting ).

worth只作表语，它后面一般接动名词，也可接名词，但只限于钱数，不接不定式。如果用不定式或动名词作主语，则要用It's worthwhile…结构，把不定式、动名词放在句末;

worthy是形容词，worthy可作表语，也可作定语，作表语时，后跟of接名词或动名词，也可以接不定式。

worthwhile和worth虽均有"值得的"意思，worth只作表语，用于be worth sth.短语中，如：It's worth the trouble.麻烦一点值得。This watch is worth this much money.这 块手表值这么多钱;而worthwhile意为"值得一做的(worth doing)"，既可作表语，如：T hese results were not worthwhile. 也可用作定语。
