worth用作形容词时在句中只能作表语，后接名词或v.ing形式。worthy既可以作表语也可以作定语。作表语时常与of连用，后接名词或v.ing被动形式，还可以接不定式的被动语态。即be worthy of sth.“配得上，称得起”；be worthy of being done或be worthy to be done“值得做”。worthwhile既可以作表语也可以作定语，后面可以接v.ing形式或动词不定式，即be worthwhile doing/to do sth.“值得做某事”。amazing survival from praising designed from in belonging for being considered less than in their search for It is worthwhile designed for old people belongs to my brother Thank you!
