It is        to read the books our teacher recommended , for they are well _____ reading.
A.worthy ; worthwhileB.worth ; worthwhile
C.worthwhile ; worthyD.worthwhile ; worth
D
此题重点考查三个短语的区别。worth只作表语,表示“价值…”或“值得…”,多接名词、代词、或动名词的主动语态;worthy表示“值得、相称或配得上”时,作表语,接不定式被动语态,或of加名词、动名词被动语态;It is worth (one’s) while to do sth [doing sth] 结构必须用it作形式主语,其中的不定式或动名词做句子的真正主语。
